is it possable to increase my 383 with more boost or do i need a ls or a big block? any body know of one and the combo?

 

is it me or are you saying you wanna get 1700hp from your 383...


i may not know allot but i do know this: that is rocket science right there my demented friend !

 

The sky is the limit, if money is not a problem. Check out this post. http://forums.corvetteforum.com/show....php?t=1435800

He has ran a 6.87 at 210 mph. Id be happy just to run a 6.87 in the 1/8!!!

 

your turbo wont run out of breath until 1300hp. You should easily eclipse 1000rwhp @25psi with your combo, perhaps with a bit more camshaft. I'd bet my paycheck on it. Did you get the email? I was having trouble 'cause the file was huge.

 

Holy f***ing crap!!!

2,400HP street legal car????

That thing sounds like a jet taking off!!

 

If you seriously want to achieve 1700hp, your gonna need a Worldproducts block or equavalent. I'd just give shafiroff or someone a jingle and tell him what your up to. They should be able to set you up with the proper shortblock.
Heads will need to flow 300+. The new AFR eliminators should do. The better the head flow, the less boost pressure it will take to get your hp #. camshaft should be 248ish/240ish with .650 lift solid roller,240lbs on the seat
Two Gt4508R's will easily push those lbs/min thru the motor. Or if big single's do it fer ya honk a GT55 or GT60 on there.
Anyway you slice it your looking at a $20,000 motor. Back it with a powerglide or lenco and you got about $4500 in trans. If the rearend survives the launches you put it thru (it wont) you'll ride the rocket thru the traps at 180-200 mph. If you backhalf it (Id go dana60) and can get your 60ft down to 1.2's you'll be on your way to 7's consistently.

 

I'm looking for a 300 mph bonneville salt flats car............BGT..........It's got to come on slow but I can do that with throttle...........I don;t want to match the record I want to destroy it(266mph or so)............I've been supercharged for 5 years so I understand and can tune them..............just looking for most hp you guys are running so I can copy them................also I don;t what to destroy the vet I have so I;m looking for some thing with a roll bar already in it.................just an idea at this time,..............I go out every year and check out the vets.............some will talk to you, some are super dip sh@ts and hide everything.,,,,,,,,,,,,,,lots of money four runs a year.

 

Well that makes it sorta easier. Huge acceleration breaks parts.
Lotsa cage to go 300+ safely.
The motor will have to sustain long blasts. I'd say 5 or more stage drysump is in order, with underpiston cooling, oil cooler is nessicary.
20+quarts of oil, a great radator with a tiny opening in the frontal area.
Your going to need some external cooling on your trans, probably a liberty or jerico out of a nascar.
Honestly buying a Ex-nextel cup motor and changing pistons would be a good way to go. Hopefully the 1.88 rod journal will be okay with the sustained loading.
The most wonderful thing about the turbo over supercharging is that a nice electronic boost controller can roll in the hp based on mph.
I like my Eboost2.

 

If it blows up trying to get that 1000 rwhp that Bruce wanted to see, im going to need your paycheck to put it back together!!

Rick, I never received the file. If it would be easier for you to load them to a CD, I can send you a mailer to send it to me with. I really appreciate you taking your time to get the pictures for me.

 

I really believe that combo capable to making that hp level. I also know that it needs the BS here there to dial it in and fixing minor misc and you should be good to go. Good luck with it rich.

Hey Bruce, its good hearing from you!! Are you back in the states? I am pretty conserative about the hp output of these motors. I am basing my statement on a 383 shortblock I purchased from Golen engines, and they build it for 750 flywheel hp. It has the same crank, rods, but they use SLP pistons. It has 4 bolt billet main caps as well.
I found the oil pump that I believe STS uses for their kits. I purchased it and have it mounted, but that is about as far as I have got with the car. I ordered a throttle cable to bypass the ASR control and I ordered a 3 bar map.
There seems to be something drianing the battery. I need to check for shorts, or something staying on all the time.
I will edit this post with a link to the pump I purchased.


here is the link http://www.rbracing-rsr.com/oilsystems.htm

 

How did you actually purchase it?

I was on the web page that was posted in your other thread, and I cannot figure out how to purchase it.

How much is it?

 

Bill, here is a link to the page. http://www.rbracing-rsr.com/oilsystems.htm

If you notice, some of the pictures are the same as STS are using.
I ordered the one for $275.00 since there is no return pressure on it. Also I ordered the 1 psi valve to prevent the supply oil from draining into the turbo when shut off.
Total price was around $320.00 with shipping, and I received it about 4 days after ordering.

 

Will do on the CD. Its not uploading cause the total file was 150mb including videos. DOH prolly shoulda looked at the size
It's all in the tune. Make sure the WB is zero'd start at low timing, But resonable A/F. No sense in drowning it in fuel. Your Iat's will likely not go much over ambient, providing the chiller system is still functioning properly.
As long as the boost is cold, the a/f is 12-1, you don't knock it (I'd hazard to guess somewhere around 12-14 deg total @25psi), w/116 in the tank it will take it. Just don't expect it to do it everyday. Duty cycle my friend, duty cycle.
Just take your time, start at 5 psi and 30ish deg total timing, and work your way up slow. Make sure the sensors are all reading correctly, esp the knock sensor. you'll learn what your individual combo likes for timing
I have a slightly smaller trim compressor, but the same turbine on my own car. It made 710 hp at a relativlely low 180kpa but I rev the ***** out of it to (7400rpm) to get that # at the low psi.
You shouldnt have to rev it that hard. Without the dry sump, I prolly wouldnt try it, you'd have a oily mess from the breathers. Lt's,sbc's hell even lsx's have enough PCV trouble with high rpm. add a buttload of boost and you got case pressure makin' a damn mess.
Seriously though, I can tell you that once you get around 700wheel you prolly will be satisfied. Without DR's it's an wild ride. With them it's a faster,starighter ride that starts breaking ship halfshafts,D44's.

 

Yes I am back home. it was a awsome trip. take your time to work on the car and once it done you will be happy with it. As BTF says, you will probably will be happy with 700whp. 1000whp is useless on the street any way. just for bragging right. All I can say is it scared the craps out of me when BFT and I doing tuning on the street yrs ago that was only at 14psi first time out testing and lost a head gasket (felpro gasket then) 14psi @28 degree. to much timing. I believe then I post up some pics of the detonated head gasket.


Bruce

 

all right you guys........ your getting a little side tracked on this post............what is the max hp any one on this board is getting? black bart claimed 1000 HP..........I think aarons up there also......but if you use race gas, o-ring head gaskets and up the super-turbo charger to 25 or 30 psi.........I'm thinking 1500 hp could be had...........by the way Bruce I also have some head gaskets that didn't work with supercharging and NOS..........kept them to show anyone interested

 

Monty's 427 with 18 degree heads and twin turbos at 20 psi gave him 1200 hp and 1000 tq at the engine.

Look at nelsons racing engines F-bomb car. If my memory is correct, it is a 406 with twin turbos that is making somewhere around 1500 hp in a early 70's style camaro

thanks guys....just what I'm looking for............engine spec's would be even better.........cam, intake, boost# would be even better...........don't want to re invent the wheel.

 

here is a tid bit on the engine build up for that F-bomb car.
on a tv show he had the car featured on, he will not tell what spec the turbos are.
