TURBO BLAZER @ THE TRACK- 8psi 30" tires

[02vortec]

this is on a otherwise bone stock blazer- 8psi & 30" tall tires-

I RAN IN THE 1/8TH MILE ITS OUR ONLY LOCAL TRACK-

8.8 @ 77mph-

1.96 60ft.- no spining just up and went-

THIS IS ON 8LBS OF BOOST AND 30" TALL TIRES (heavy as hell)

boost launch 8lbs- hammer it right before i let off the brake and right after the 3rd light turns on- and ended up with that- ran a 9.2 @ 76mph with a 2.3 60ft when i launched @ 4psi and bogged

what motor is this?...sounds like an LS/LQ motor since your using that software and all...if so you need to figure out what the hell is wrong..255 is worse than stock.

[02vortec]

its 4.3L running 8psi......... read the sig again

[SnowMann]

You may want to read your sig again since it makes no mention of a 4.3

It is an 02 Blazer and he did mention is was otherwise bone stock :|

[02vortec]

lol its 2002 blazer- i said it was stock- AND IT SAYS LATER 5.3L- which means it doesnt have it yet

[SnowMann]

Oh noes...Ninja edit of the sig FTW!

and your TR garage is contradictory since is lists a L30 which is a 305 V8

Anyway IIRC from when I had my ZQ8 Sonomas...the stock bottom end on the L35 is good for almost 325-350whp on a safe tune. You mention being untuned, so what are you using for fuel managment/timing adjustment?

[02vortec]

it has not been dyno tuned- it has a base tune from a well known 4.3L tuner- i put it on the dyno so i could get the a/f ratio checked out and make sure it was otay- its a 10:1 a/f ratio-

im running an adjustable cartech fmu and procharger inline fuel pump-

BTW it has been proven many times that the 4.3L bottom end can take 400whp in stock form.... you just have to get the fueling and tuning dead on- im gonna be going with a full MPFI set-up sooner or later so i can start pushing the boost up to 14+

Its cool they've been able to push the envelope that much since I had mine. Try to understand that I got rid of my last Sonoma over 4years ago and back then the people running over 350whp risked cracking pistons...thats why I asked what you were using to control timing/fuel?

[02vortec]

yeah- we have even started to put 4-bolt mains in bs block- thats what i plan on doing- im gonna be going to a MAF-translater pro and run speed density- also gonna start building a custom MPFI set-up for her
