Just figured i'd post up my numbers.. also wanted to know if the Air/Fuel ratio is where it should be.

Mods are pretty much just intake/cat-back.

Dyno graph - Difference between 1st run was with cutout closed and 2nd was with it open.

 

Air/Fuel seems pretty lean...
You should want it around 13:1, and your 14:1 and above....

Damn! A 13.3 with just a k&n and borla. Please tell me you have gears or something. I have an slp intake and shorty headers(the crappy duel cat ones) with a cut-out and i hope to make it out of the 14's. Look like you have a good running lt1.

 

Yeah, looks pretty lean to me.

 

Those are impressive track numbers for that power. I make about 30rwhp more and am a tenth slower, but a few mph quicker.
Once you get headers that cut out will be more effective. Mine went from a 2hp difference when i had just a cat back to a 10hp difference when i had headers and a ory.

 

My dyno numbers are also w/ 3.73's, ls1 drive shaft, and tune. But the 13.3 was just with the intake and catback.

Went to the track w/ these mods but now i'm having tranny problems, hitting the rev limiter on 1-2 and 2-3 shifts but still went 8.50 @ 84.5 (i'm impressed by the trap speed) 1.90 60ft.

I'm pretty confused about the dyno numbers... figured i'd have a good bit more.

 

Nice man, I don't plan on racing mine any time soon but I'd be happy if I hit a 13.75

 

8.5 in the 1/8th? .. i strongly dislike you... all i can manage is an 8.8 at ~79mph on a 2.1 60'... and similar mods granted it was spinning the 2nd gear shift.. still low mph lol.. oh well pretty ncie runin car ya got
