meth even with low 10-ish lbs of boost ?

junk c5

No, not necessarily. I think it might come down to your tuners capabilities. what it makes on 94 octane and an a/a cooler before detonate begins. If he's happy with it then meth isn't necessary. If he wants to push the envelope then add meth.

sweet. fast cars are vegetarian drug addicts (E85 from corn, METHanol )

junk c5

That's a nice example of a pumpgas street car

richincanada

nice !
Thats an LS3 (6.2L), correct ?

junk c5

Yup. A better foundation. I believe it's around 10.5:1 comp as well. That ls1 probably wouldn't like 700 RWHP for very long either. I burned a piston in my ls1 at 600 RWHP

richincanada

Too easy to get carried away...500-550 at the wheels is PLENTY for a 3200LB vette driver.
(Although the Gen 4 aluminum L33 5.3 would be my budget 'gooder' engine )

junk c5

Keep your eyes open for an L33 just in case to tuck away in the corner. This turbo stuff gets out of hand quickly. Lol. I got 2 solid years out of my ls1 at 565 RWHP and it was a blast.

richincanada

No doubt lol
Hey, whats the clutch to get, there's everything from the $500 LS7 clutch to the $1000+ Monster ones. Again, 99% street car, Might put some DRs on and run it down the 1/4 on occasion. what about the "rearend" ? bracing etc.

junk c5

The clutch is beyond me. I've got a level 7 4L65e. Crawl up under it an see if it has a 3 rib differential. That's a big plus. A couple vendors sell trans braces which are always recommended.

junk c5

You want the 3 rib on the right

richincanada

awesome...thanks !!!

junk c5

Depending on which gear it has, you will probably find that it's cheaper to find a 3 rib differential with a 3.42 gear is quicker and cheaper to swap out than changing a corvette diff gear set. I couldn't believe the cost from a rearend shop in Chicago. My car came with 3.15's and I got a 3 rib diff from a low mileage 03 Z06 for around $550.

Then I was able to sell my 3.15's to a guy running 1/2 mile events to recoup some money

richincanada

That's the awesome thing, not only is he a class-A mechanic, he's also a car guy and a damn good fabricator, he's worked in Tranny shops, built motors, turbo kits, changed gearsets,can do awesome body work, etc. He'll definitely find the most cost-effective way to do things.

I just want to get it all figured out so when I get my C5, it'll be easy, 2nd nature !

[QUOTE=richincanada;1594213254]found this :

stock LS1. stock heads stock cam on 10 psi tuned on 87 octane. 60 injectors 340 fuel pump with hot wire kit.

Stock heads cam and 87? Im not buying that.

I have an STS setup w upgraded turbos, dead stock, 10# with meth and 534/556ft/#

[QUOTE=StatmanRN;1594218216]I'm ALWAYS skeptical on dyno numbers when somebody posts a number which seems higher than normal. I always ask what is the cars ET. In lots of cases guys say they don't bring their car to the track. LOL

richincanada

[QUOTE=StatmanRN;1594218216]I agree, that sounds like a very "generous" dyno.
534/556 seems more realistic...and "even" that is outstanding. Any track et/mph ?

A post from when I 1st put the turbo kit on my stocker.

Wow, that's awesome on 8-9PSI !!! How has it held up over time ??

crap, just checked and the 2015 Z06 is like 570/590RWHP
you made 525/577 ! what RPM do you shift it at ?

Turbo-Geist

The stock engine lasted about 4.5 years and was over 800rwhp at the end. It would have lasted a very long time at the 500rw power level. It got me into the 9s with a 6-speed.

I think with the stock cam, I typically shifted around 6200 rpm.
