AMP Built 427 F1X C6 coupe - PICTURE WARNING!!!!
 

Well, its been a long road and i am finally at the point where for now i am happy with the car.
Ill first say Thanks to Sam and Bryan @ Advanced Modern Performance out of arlington TX. They have been the only shop to touch my car since i went from heads/cam through all my combos.
The pictures do not do this build justice. The attention to detail that the AMP crew showed is incredible. The car drives so smoothly you would not think it has near the power it does.

Car started as a heads/cam car.
Then added a 175 Wet shot.
D1SC+ stock motor
F1R+stock motor.
f1x+434
f1x+427.
And here we are today.
The build as it sits (and Sam or Bryan Feel free to jump in and correct me.)

LME build ~9.9:1 427 with Mast 305cc Black label heads.
DP Fi cam
ARH 2" headers
Procharger F1x with DP HD J bracket and DP direct drive.
AMP all custom Cold side piping.
AMP moddified Base Procharger FMIC(from my d1 kit) with modded inlet and outlet ,3" in 4" out, and outlet End tank.
Dual Tial Q bovs on the end tank.
All pulls made through a DP Big mouth intake + filter.
93 octane pulls have a restricter in the intake to restrict boost.
LG drag spindles.
Spec Super twin ST trim clutch.
ID2000 Injectors.
AMP custom fuel system.
AMP custom Catch can setup.
Precision Metalcraft Ls7 intake.
10 rib pullys
8" IW crank
4" Blower pully.
all the dynos im going to post for the f1x and the old F1r were with the same pully combo.
I am sure im forgetting something.. but time to post a BUNCH of pictures.
AMP also clearenced my front calipers so that i could fit the weld 18x7s up front with out spacers.

And now the power numbers.
here is 93 Vs c16
http://i526.photobucket.com/albums/c...ps74d77ff3.jpg

This is the 434 f1x VS the 427 f1x . The old setup i had 1000cc injectors and was just out of injector @6700. The old setup was unrestricted. the new setup we had to restrict it down a bunch to keep it down to 1200.

This is the f1x on KILL(c16) vs the old f1x 434 setup
http://i526.photobucket.com/albums/c...psccebfb26.jpg
Finally this is the 434 f1R 8"/4" setup vs the 427 f1x 8"/4" setup

quick Start up and idle video. (keep in mind its in a closed shop so its actually not AS loud as it seems in the vid:))

Looks slow.

Holy moly doughnut shop! That's killer man congrats.

for tx is is.. Maybe C team power:(

Thanks!!

That's crazy to see the power difference

Not bad at all. :) Wish I knew how much the intake added.

here is some of my spreadsheet bench racing.. @ Ti on my F1r @ 6600 rpm shift point the car was down to 854/676. the shift would drop it to 4700 which was 801/877.
on the new setup. 7500 rpm shift point.. im @ 1320/943 @ 7500 and when i shift it drops to 5200 which is 923/930.. should make a nice diffence in trap speed:)

Congrats on the amazing amazing build......

Things to take note.... F-1X's are wicked power makers.

And to think people said, you can't make over 700hp with the ProCharger tensioner. :)
Even though their are plenty 800,900HP cars, this thing is belting out nearly 1,500+ at the motor. Just awesome!


Can't imagine the difference in the way it sounds after 5,000rpm compared to the old combo....!!!!

one thing to keep in mind:) the blower is 100% NOT out of power.. we still have a 3.8" we could throw on there. but right now i want to be able to rev it out to 7500 rpm..

Congrats man. It's a complete package. Now do yourself a favor and leave it the fuk alone and drive the thing. :thumbs:

This is the math that can put a smile on your face! wow!
:flag:

Actually you are out of gearbox, (just not impeller).

The older R's and other blowers, really hit a CFM cap up top, and even though you can spin them harder, the dyno curve will flatten out because lack of CFM change, and drive load power increase. So most people really didn't overspin the older blowers.

As you can see people are finding out the difference between the F-1X's and older F-1R's, the faster you spin them, the more power they make.
But the gearbox's still have their limits.

However, many people are ignoring the MAX RPM limit of the F-1X (72,000rpm) due to how much power they keep making with the new impeller designs, and are running into gearbox failures. (The blower is only rated at 1,300HP of Crank HP worth of CFM. And you are now making that to the wheels)

I mention this because you stated you are running a 8"/4" pulley combo, and 7,200 engine rpm. Which means you are at 77,760 impeller rpm, thus a good distance over the redline. (And the 3.80" pulley, would push that even farther into the 81,000 range)

Enjoy the power! But if you can keep her "happy" and at or under the 72,000rpm redline, your blower will thank you :)

Back when blowers were smaller, there was much more buffer in that redline, but with the massive load force these impellers are putting on the bearings, over spinning is not a good idea.

If you are over the redline of the blower (as you currently are) thats when things like, intercooler pressure drop come into play. Make sure you have the least amount of pressure drop across the core, instead of putting that 3.80" pulley on and risking a gear box failure.

Can't wait to see real world results of this new combo. :)

im shifting at 7500:) which is closer to 80k:) i have a spreadsheet i made that will calculate and plot blower vs engine rpm for any pully combo:)

btw.. street duty i will still shift at 7000.. 7500 is reserved for "special occasions":)

I just looked at the 7,200ish on the dyno sheets, don't make me cringe even more knowing its really 7,500. Honestly, your saving grace is likely going to be that serp. belt. Cause hitting a revlimiter at high RPM, with a gearbox that over spun with a cog belt, easily would end in disaster.

But as long as you know, then its all good. Just being honest and stating that with all the hype around the f1x, and that 99% of it is people raving about the power it makes, those few that keep complaining about gearbox failures are likely in the same rpm range you are. If they break, its pretty easy to tell why, the bearings have very tell tale signs of what load they have tried to live at.

Now if we could just spin it to 100k ;)

Congrats man this is one clean build... Good luck w/ all that power it must pull like a fright train on the highway... Id like to see how much $ you have into this car holy **** between all the set-ups... Was it worth it? (:

That's crazy power WhiteLightening.... You guys did a killer job on that car!!

How much boost were you seeing on the 1324hp ballz out pull? How much on the pump gas/meth pull?

Are still using 3" pipe from the blower to the intercooler?

I've been contemplating an X for a while, but I don't want to re-do all my piping again.. I'd just like to make 1k to the wheels thru the auto on pump/meth...

Looks like the F1R was stronger up til 5k and then the X takes off and slaughters it from there. Mine is never under 5k at wot anyway...

I'm thinking an X with a wastegate setup would be killer..

Youre making over 1500 crank HP right now...:eek::cool:

Lol ppl just ratte off 1200whp like it's a corolla these days. Insane numbers

Shift point is 7500.. rev limiter set to 7650. so unlikely that ill hit it.
Also i dont rely on the factor sluggish tach. i have a digital tach with a BRIGHT shiftlight..Also, the time it will see over 7000 will be very limited
http://i526.photobucket.com/albums/c...2/DSC_0133.jpg

honestly. less than you would think. I sold my previous blowers and any other things i swapped. When i bought the car an 08 z0 was going for 55-60k and i bought my coupe for 37.So i could have had a z0 with a d1 or my coupe as it is setup right now.

c16 pull 30#.. 93 pull 25-26#.
i think the piping from the blower to the IF is 3.5" and then 4" from fmic to TB.

AMP Really made this build awesome. I wish i had more photos of the car coming together.. so many cool things you cant event see..

Back in the day
 

I will agree . You know how many people start by adding a cai and headers and end up years later with a street monster . I like your car too my friend .

here is the sad thing.. even with 1300 rwhp.. im not even competitive in the Texas Speed Syndicate Texas Invitational lol... there will be 5-6 cars over 2000 hp TO THE WHEELS!!

Crazy huh . That was outlaw class power when I started back in the day lol . Now you say it's class c . Well it's a nasty street car . Class A .

thanks!! the AMP guys really knocked it out of the park.. i HIGHLY recommend them to anyone who can make the trip to DFW!

Great results, every combo I've seen with those heads have made huge #'s my car has the same cubes boost and compression and on c16 made 1025 rwhp with a 4l80-e. It just went 8.80 @ 162 I could only imagine what another 300hp would do ! Gives me the motivation to change my top end. Good luck with everything and I'm curious on what belt life will be it's clearly not slipping or enough to care about anyways.

Awesome build! Congrats

David car looks killer, hopefully I will get to take a peek at fall Ti. It should make a hell of a pass. The boys at AMP did a killer job.

Monster! Car has to feel like a rocket up there

me too!!!

there are only a few small things left.
(1) get new Stock front lowering bolts to bring the front of the car back up a little.
(2) Some more drivability tuning. Every time Sam @ AMP has returned the car to me he has made sure Drivability is as awesome. I can not express how timid and mild the car drives till you put your foot in it.
(3) Updated Procharger Tensioner.. Mines oooooooooold from my original d1 build :)
It felt pretty good @ 1100 on the old setup.. i cant imagine 200+ rwhp hp more and almost 1000 rpm of more power band.

That is one of the reasons we are still producing the older blowers.
The "x" trims, and newer race versions of the F-1C (believe it will be named F-1Cr) really shine in racing applications, where high RPM power is where they live at. The older blowers do still shine in the lower/mid rpm/hp range.

Its all about having the right blower, for the correct application. (cam/motor size/ect)

yup.. for me 10-20 rwhp under 5000 didnt really mean a whole bunch to me. most of my racing is above 5000.. and the difference between the R and the X was Crazy. keeping in mind im using the exact same pully combo on the R as i did with the X...

i cant wait to get my new procharger tensioner in so i can go drive my car:)

I have to wonder what kind of top speed you can get with power like that!? Think you'll ever get the chance to find out?

im on 15" mickey thompsons.. my goal is to shoot for 165-175MPH at events like the Texas invitational. i know @ 760 rwhp it pulled over 200 mph with ease on a "closed test track " :) .. but i dont feel comfortable throwing 5th in the Stock trans @1300 rwhp:) maybe with a zr1 trans or a built trans. but for now.. 180 mph which is were my 4th gear ends.

i havent done the math of what the possible top speed is with the power and gearing though.

Very nice build!

Amazing results! This has to be the most power with a supercharger using an lsx platform in a vette?

i THINK there are a few f2 cars running around.. im pretty sure they should make more than an f1x... last one i know that made 1400 was more of a Dyno spike.

Also.. this wasnt a " all for show dyno pull".. for that we would have put the 3.8" pully on and put down 100-150 rwhp more:)

this is the power level i plan to run on a daily basis rather than a shoot for the stars number.

Thats ****ing sick... 13XX is NO JOKE.... The number up top from before and after are insane... New engine should pull like a freight train compared to the old one... Congrats:thumbs::thumbs::thumbs:

Thanks!! it seems all the bigger power f1X cars i have seen went to Air 2 water.. where as im running the FMIC core that came with my d1 kit with modded end tanks..

Congrats!!!! That's a badXXX setup right there.

Congrats David. Can't wait to see this thing at TI.

Super clean build. That's some serious power you're putting down. Congrats and looking forward to some vid's.

MEH, kiddy ****......

Or atleast pull the air filter/pipe off and throw a 5" velocity stack on it..You dynoed it in a true "street" trim.... Killer numbers..


No concerns about 25-26 psi on pump gas/meth? That's a lot of squeeze, especially on a big motor with big heads and big cam...

I see 21-22 psi with the F1R at 6600....At 7k its around 23 psi and I CRINGE everytime I look at the log... And this is on a small 402 with a baby cam.... I'd be over 30 psi easy with and an X and your dialed down combo.... I seriously doubt 93/meth will support that more boost, or anywhere close to it..

we didnt have a stack laying around. but Filter/no filter made minimal difference.. keep in mind its a 4.5" or something pipe on there already.. its HUGE.. Also, i wouldnt run it with no filter.. so what ever it made wouldnt be a real indication i have cases of torco in the garage:) ill just add 1 bottle per tank for safetey Torco :)

Also.. if i know im going to be doing a lot of racing.. i can always just dump a few gallons of C16 in and leave it on my 93 tune "just incase"

Amazing numbers and work Congrats man.
What's the engine compression? Any reason for going from 434ci to 427ci?

I can't imagine shifting at 7600-7900rpm :eek:

the 427 is around 9.9:1..

Would rather not talk about the 434 .. it was build by a reputable engine shop who apparently did a piss poor job at assembling it.

Hector.. you look like you lost weight in that picture :)

very nice build and excellent thread!

With F1X, how much boost and power it makes with restrictor and with kill mode (c16)?
since all of the runs you used DP big mouth with filter, right?

Good luck with such crazy power...

c16 Kill is just below 30#(no restrictor)
93/meth is 24#(with restrictor)
We have not dynoed c16 with restrictor since i will never run like that.
I have 2 DP Big mouth setups. one with a restrictor in it and one with out. that way i can just undo one bolt and swap the intakes and then flip tunes.

almost 6# boost difference! that is a big difference in boost and I assume in power also!

I have also similar setup with 2 DP big mouth filters and the difference between them only 0.5" diameter,,, I was planning to run on kill mode without any filter on track ,, did you try that to see how much it will make?

My car made 1060rwhp with #23 boost with restrictor...

with out the filter on kill it made minimal to no difference.. not worth for me to run with out the filter.

Are you running air to water or air to air? im still have the core from my base D1 kit with a 3.5" inlet and Custom outlet endtank 4" outlet.

Thanks for the information,,,
I'm running A2A DP core... and my transmission is 4l80e...

How much the IAT reading on kill mode? mine on track reached till 184F on track on the 3rd gear...(timing were pulled as set in IAT vs spark table)

Ill have to check with my tuner.. i know on the dyno IATs stayed pretty low owing to the Meth... are you running meth?

That is one wicked build!! Sam and Bryan are producing some impressive results down in Texas.:flag:

Thanks! Glad we upgrade to arh headers..:)

Nice 8 second car you ve got there

Wow David.... Just wow....
I remember not too long ago when I purchased your F14's that your car looked like a 4x4 over at AMS w/o engine, Drivetrain.... Not only does the car look great, but it is a beast!
Kudo's to you my friend!

at AMP :)

and thanks!

tires
 

what tire size do you have on the car

325/50/15 out back
225/45/18 up front.
Weld says you a spacer to fit the 18x7s out front.. But my builder clearenced them like a boss!!! No spacer and they look better than new.

http://i526.photobucket.com/albums/c...ps12e30cb5.jpg

nice...time to go drag some azzzzz

Im really looking forward to Ti...

Something that interests me. i saw a 1260ish f1x C6 with A2W and a Volute.. and one in the middle east making 1310 with a2W and Volute claiming to be the "highest hp f1X vette"...

i wonder who has made over 1324 with A2A and a filter..

Faster as in "capable" and actually running them are two different things. False claims of grandeur. TI is the place to show those capabilities.

Procharger tech, i wanted to shoot you a few questions.. but it seems there is no way to send you a private message.... LMK if you have any other way of contact.. i have a few questions :D

So your car started as a base c6 but you added the GS / Z06 dry sump system? After checking out the pics some more I like the breather set-up you have, so they ran in into the old oil fill for blow by reasons?

when i bought the original 434 it was from a z0 so was dry sump.

It was fairly cheap to convert my car to z06 dry sump. The original catch can system was just not adequate at the new boost level so was filling up. we went to the new system with bigger lines and all of those issues went away.

I like that setup a lot very cleanly done :thumbs:

Looking forward to dragging this thing and dumping the laundry!! Just kidding haha looks great man, awesome numbers I'm sure you're very pleased with it.

Sam tuned mine last week,did a great job .love the manifold

I have personally watched your car come together David while I had my car up there letting Bryan and Sam change my tune after the DP big mouth intake. There was no expense spaired in your build and its a car that is built to handle the power your making NOW ;) Like I was saying there custom fabrication with the piping really make a huge difference while still using the factory procharger intercooler and basically maximizing all that intercooler can provide. Bryan thinks outside the box and when Sam told me how much extra power you got just out of the custom piping blew my mind!! I have seen this car run and it sounds like a fighter jet lol. Having that much power that you can rely on is absolutely amazing and AMP made that possible for you. I saw your runs out at TI and I dont even think you were in "kill mode". Its amazing to know that you can have a 1500hp car that you can get on and get on and know it was built correctly to handle such power and torque. Congrats on your car man and start coming out to Coit and Bush on Fridays and show everybody who is boss ;) I also watched this car on the dyno after the clutch was broken in and i couldnt keep my mouth closed haha!!! And for AMP, this build is what is expected when it rolls out of the shop for delivery!! Props to AMP and there customer service!

Thanks for the kind words.. when i started on this project i had no idea where it would go. I say go instead of end because im sure we are not even close to finished :)

There is no one else besides AMP i would have trusted for this build. Every step of the way, every decision is justified and explained, and even with the power it put down now which i *THINK* is the highest boost only street centri c6 currently running around (besides maybe some race car f3 monsters drag cars).

The runs @ the Texas Invitational were basically shake down runs @ 1260 ish. so now im almost 200 rwhp higher. no nitrous... just by AMP going out of the box and making changes that made the setup more efficient.

The CRAZY part is talking to sam he said " Look, if you want i can MAKE it make 1500... but where it is at now is where i am comfortable with you taking it out and beating on it over and over."

almost 1460 rwhp BOOST only THROUGH a filter, with a stock ECU... Sam @ AMP is a freakin Rock star!!! The whole team there is. Bryan, Serg... everyone..!

Congratz on 2,000whp.

What was the boost difference from the f1r to the f1x with the same pulley? im doing that swap now and i assume the F1x would make a lot more boost.

when we just did the blower swap on my old 434, the F1r Peaked @ 20# and the X peaked @ 25.6#.

it was a jump from 926 rwhp F1R to 1130 f1X...

my current setup the same pully combo makes a peak of 29.X# and 1457

That is insane! Are you running a wide body kit on the rear while keeping the front end stock?

Thanks you... Exactly what i needed... Appreciate it... KILLER car

yup.. OEM z06 fenders out back.

Need the front fenders now David! lol!

no thanks:) i like the narrow front and big booty... :)

I finally had a friend of mine who is a photographer takes some pics of my car..

More to come after a fresh detail :)
This is what AMP Crammed all that motor goodness into:)

https://cimg3.ibsrv.net/gimg/www.cor...637a8958c0.jpg

Yep. I think I was the first one to run the 18x7 RTS up front on an Base model front fender with the 225/45/18 tire. I tried it with Z51 brakes and no go. Swapped to base brakes and still no go. My answer was a 5mm spacer which has worked well for me with ET lug nuts. My feedback eventually made it into the Weld catalog because apparently they only set up the wheels off of drawing not an actual car. This clearance also works as shown. I had planned to do that but it turned out that the 5mm spacer did not push the wheel out as far as I thought it would with that size tire and still cleared the stock caliper with a fresh pad in it so I left it alone.


Though I have to say that I get a little worried about my brakes at 8XXwhp at 1/2 mile events. I can't imagine 1300 without a better brake setup. Car looks great though and isn't helping me stay away from a rear wide body setup even though I am invested in two sets of rear wheels for the base rear fenders.

looks epic! i love the wide rear body and narrow front, makes the back look even wider than it is.

so the last roll race event my best mph was 173.. 60mph start and race for about 1400ish ft.. with the dba blanks , z51 calibers and agressive pads i had to pace my braking.. my first run i put my foot all the way into the brakes and the car started to slow down so agressively i scraped my front air dam on the ground lol.. now i lift and ease into the brakes.. i would not go below z51 caliper and the dba slotted rotos with a good pad stop pretty well..

Show, and GO... Looks great David...

What paint did you use on brakes? Looks fkn mint!! :cool:

my builder used High temp caliper paint i believe.. hell if you think i have the patience do grind and grind and grind to clearance the calipers you are mistaken:) my builder/tuner wanted to make sure it looked perfect and did it all on his own..

I have DBA 5000 slot rotors with a stock caliper and Hawk pads (not the most aggressive ones) and it stops good for normal use and drag strip runs but coming down from 170+ is a challenge with a short shutdown area. :cheers:

Very Clean Install!

in my experience the z51 brake setup with good motul high temp fluid and some pretty aggressive pads works ok for high speed stops but not repeatedly, at the track I find the first 160+mph slow down is fine and feels great but if I don't give it plenty of time to cool down the next step is big time "pucker factor" and you can certainly feel the setup degrade. I bet some bigger z06 or zr1 setup would obviously be superior but I think for street or intermittent runs the z51 is "ok". with >800whp though you can certainly overheat them just doing mexico highway runs too.


have you put this vette on the scale yet? very curious what it weighs

it's a PIG with me in it lol

3850 with my 325# ass and a full tank of gas..

top notch build Bud! cant wait to race it and get beat..

thanks man, that's about what i'd guess, full tank of gas is ~120 lbs and then driver at 325 so the car is like 3450 with a 1/2 tank and no driver.

this is iron LSX block right?

impressive how mild that cam is for the power too, in the idle clips that is an extremely streetable sounding setup for >1,300whp capable setup. badazzzzzz!

Yup.. Lsx 3lt z51 car

thanks, such a crazy awesome setup.

and how does it hook up on the street with those 15" mickey thompsons? what gear can you go full WOT at?

3rd at 60 is hooks pretty well..

Sick build David - Sam does amazing work. Congrats man!

Sick build! Do you ever have snapping ac belt problems at this power level? How did you fix?

No problems with the AC belt swapping, but i did put a new one on when i put on the 10 rib setup...

I mean snap like break? None of yours ever break? Is your Ac belt still 4 rib?

https://cimg5.ibsrv.net/gimg/www.cor...42e5d1cf30.jpg

Does the flip drive, direct drive, whatever it's called use a spring loaded tensioner on that belt or is it all solid tensioners?
