Yes, I have considered it, but need to do more research on it. I have been getting conflicting answers on a seemingly straight forward question. First, I just wanted to know if it was mandatory to use your windshield wiper reservoir for the meth - I have heard no, but no one knows if anyone makes a separate one for the C5. Then, I hear some people just use winter blend windshield wiper fluid for their injection, but the tuner I have was saying hell no to that.

I have seen standalone meth tanks, I think snow and devils own makes them and probably many others... you could probably hide it under one of the front headlights or in the rear of the car somewhere... I would stick with alkycontrol though and just buy a separate tank and a new line... you might even talk to Julio at alkycontrol and he might be able to put together a custom kit for you... I would also run straight 100% meth if you intend to use it to make power (which is the best way in my opinion)... windshield washer fluid has a small amount of meth in it but the people that are spraying that are probably only using it as a safety measure

it's been awhile since I updated this, I tore the car down late last year to build the drivetrain and that turned into a fiasco all in it's own but it's back together and running good... here's what I added:

-built 08 z06 tr6060 with zr1 5th/6th gears
-09 z06 diff case with wavetrac diff and dss output shafts
-dss 3" driveshaft with dss poly couplers
-RKT56 conversion mounts
-went ahead and changed my headers out to 1 7/8's since they were just hanging there

put it on a dyno out of curiosity since I never got around to it after making the changes from last time... I realize they let off early and it had a little more in it but I'm not complaining, it did ok



I wanted to thank Bret again for all the tuning/advice/putting up with my sh*t along the way lol, also thanks to Jason at TDP for building the trans and going through the trouble of finding the right gears, Rick at RKT56 for the mounts and also the correct info needed for the gears, Shane/Jeremy at RPM for taking care of my diff, Anthony at LG for taking care of my headers/test pipes... it's good to have guys like this around that you can trust and count on when you need them

Fantastic results man! How do you like the trans ratios? I recently installed a Gforce t56 with C6Z 1-4 and ZR1 5-6. I like it pretty well. 6th is a bit higher RPM on the highway at cruise but its ok. I really need to change my 1 3/4 headers to a 1 7/8.

neutron82

I like the longer 1st-3rd gears, you stay in boost longer instead of shifting too often like the c5z ratios... I usually cruise around on the highway around 80 as long as traffic permits and its right at 2k rpm, maybe a hair over, but it doesn't bother me... gas mileage isn't a big concern and my exhaust doesn't annoy me so it's all good... it did take some getting used to as far as from a roll because I was used to being in different gears at a given speed with the c5z ratios and with the new ratios I can often be a gear lower at the same speed... I also picked up a set of mickey thompson et street s/s that I will try out when I wear out my nt05r's

PEETYZ

Yep I noticed same thing. Sweet spot in 2nd was 40 now its like 50-55. I assume you have the older 5-6 ZR1 ratios like me. Your trans should be 2.66 1st, 1.78 2nd, 1.30 3rd, 1.0 4th, .81 5th, and .67 6th.

I had some really good runs with my friends ECS GS that makes 640/610 vs my 715/610. That GS having the same ratios as the C5Z made things interesting because either I was in my sweet spot or he was in his. Top end wise the new ratios are much better. His car does make more low end and mid range than my car as well.

ajrothm

That sucker was still climbing.. Probably would have made 825-850 if they pulled it to 7k...

It does have a weird dip up top like the belt slipped (or tire spun) or something but... Damn good power and power band.

I bet she rolls out hard on the highway with the 6060.

Bret knows a thing or two....

TXGS507

Bad *** bro!!!!

Jason913

Very nice, well put together. I have the same trans setup in my car, love it for boost

Mike Farris

Am I reading that right? 80 hp from the header swap? Same pulleys and boost level?

I'm about to swap my 1-3/4" for 1-7/8 stepped to 2" on my maxed out D1. Would love 80 hp from that.

neutron82

on my z06 cluster the 5th/6th ratios came out to be .80/.63... it would have been a crazy amount to swap to the zr1 cluster and actually not even worth doing, it would probably be better off to buy a zr1 trans from the get go in that case... even if the gearing was to his benefit were you able to pull him up top?

yeah he told me the same thing... I have been thinking about starting on a motor, nothing crazy just something good for around 900 but I haven't decided on a plan of action yet... if I actually get that going then I might turn it up a bit and see what happens... I logged that pull and right around the dip in the graph they let off just a smidge and boost dropped roughly .5psi so that's probably what caused it

thanks

I wish!... after the first graph I added 4psi along with the other parts listed but never redynoed after that change and when I had it apart doing the 6060 swap I decided to switch to 1 7/8" headers since I was right there anyway... so the graph I just posted reflects the 4psi and header change, not really sure how to compare that since it isn't apples to apples

PEETYZ

Heck yea I pulled him up top =) Got some good vids if you PM me your cell number again.

romandian

so i have been thinking:

02 zo6 rated 405 hp (out of memory)
405 x 0.88 = 356 whp
356 x 1.83 (12 psi) = 650 whp
650 - 70 (blower loss, is probably higher) = 580
700 whp (@6250)/580 = 1.21 (21% gain from cam, headers and exhaust, makes sence)

356 x 2.1 (16 psi) = 749
749 - 90 (blower) = 659
659 X 1.21 = 797 (so new headers got you nothing)

changes in charge temp. ignored, assuming they are near zero with meth.

neutron82

I'm not really sure, I never did a fair comparison... the first dyno was with 1 3/4 and second was with 1 7/8 but I had also added 4lbs of boost along with the other changes mentioned... I did have the 1 3/4 installed and tuned with all the other changes but I never got a chance to dyno it that way before I tore it apart to do the drivetrain and just decided on a whim to try the 1 7/8... I wish I did dyno it so it would be more fair of a comparison but oh well, it picked up power all over the board so I'm happy

neutron82

it's been some time since I've updated this lol, a few things have changed over the past couple of years

-switched to e85
-swapped fic127's to fic 1650's
-added fore fuel rails and got rid of the fast rails
-added a couple pounds of boost

Bret finished up the tune and wore his dyno out, big thanks again to him for taking care of it... I'm fairly confident that my car would not be alive today after all it has been through, let alone making the power it is, if someone else had been tuning it!

well here's the graph, keep in mind this not from the same dyno as the previous graph I posted... Bret didn't have a dyno at that time so it was street tuned and run on a local shop's dyno at a later date, the graph below is from Bret's dyno


I snapped a pic of the car while cooling off on the dyno between runs


and here's the engine bay as it looks now, it's basically the same scheme but a few small things are different

silver408z

Awesome results and great looking engine bay. Still the d1sc? I see my car on the lift next to the dyno. Its making progress!

neutron82

yeah still the little old d1 lol... I'm not spinning it to max impeller speed but you can already see the power curve flattened out so adding more boost may not add much for the risk so that might be about all it has in it... I could send it out and convert to a d1x for a little more but I won't be going all out with an f1x like you... I want to see what your car does when it's all said and done, the few times I heard it run it sounded like a beast!

_zebra

sounds like mine'll be out of y'all's way this weekend, so there's a lot less frustration & head-scratching he won't have no more
are you still building boost on the top end, or is that tapering off? and are you still on stock heads? with your torque falling that much above 5500 (assuming the manifold pressure's still there), i'm guessing they could be holding you back.

...but then i don't really know much more than book stuff & theoretics when it comes to engine building.

Turpid porpoise

That's gotta be a fun car.

Which valve covers are those?

nickalltogether

Incredible engine bay- subtle and clean. Also incredible number for the stock bottom end LS6... hanging strong in there.
