Fastest with completely stock motor (internally) ?

[Turbosix6]

I have run a best of 11.51 @116 with 120k and the original valve springs. I am only running 22lbs of boost with 100 octane and my mv at 800's through the traps in third.

I honestly believe that with a full race suspension, slicks and skinies (currently Et streets on 16" gta wheels with stock suspension) with 25lbs of boost and 110 gas, she will break the 10's.

The only problem I can forsee is either getting a taller tire or switching into 4th gear cause shes all out of rpm in 3rd already.

Gotta love these cars...

You're running the same wheel/tire combo I used to.
You're out of rpm through the traps????? I always go through at 5200-5300.

Ooops, forgot, I always have the TCC locked, maybe you dont?

i don't use a manual lockup on my tcc...i have the switch set up for it but i don't think it works...i don't think my tcc locks up anymore...

anyways i am switching to a taller slick next spring to the 28's...maybe this should help me along with high octane and cranking the boost!

Well, Stangbanger has me covered but I like to see my boost gage still reading below 30 psi . I typically limit myself to "only" 26-27 psi for the times shown in my sig. No race chip either, just 22 deg spark to help keep the head gaskets in the motor at high boost.

Full weight TTA, 13k miles, valve covers never been off, TE44, OE injectors, OE turbo exhaust elbow and exhaust (turbo back), ATR 2.5" DP, Walbro 340m, powerplate, stretch IC, and an adjustable FPR..... No boost launch on Nitto's, 24-25 psi through the traps, 50/50 mix of 114 and 92 with an SMC alky kit = 12.13 @ 119.84 mph on a 1.91 short time! I believe this combo has yet another 3 mph in it.

All stock cept springs.stock IC,TB,cam etc..My IC still has the screen on it

Sig was done last thursday nite..ran 11.69 then 11.622..low 20's for boost

I can see low 11's on upping the boost and getting more aggressive timing
