Final Pump gas numbers from FMS
MY dyno reads .7-.8 lean so the 12.6 A\F is actually 11.8-11.9 A\F. I can run this kind of A\F due to the combustion chamber design,cam design and the big *** intercoller up front along with the efficient turbo. The intake air temp is located in front of the T\B and in these dyno test only gets 5-10 deg over oustside temp. If I was to dyno at 11.0-11.2 I would be blowing out black smoke like a diesel. This motor was built as a pump gas setup from the beginning. My N\A motors make the best power at 13.8-14.0 on my A\F display.
Now this is JUST a dyno test for now and IS NOT the final tune for the customer!
Do any of you that preach 11.0-11.2 actually READ the spark plugs to see what is going on in the motor?
Now I know why its hard to post up results without everyone jumpin in

TTT
Like Allan said, at 11:1 my car looks like a diesel going down the track, and runs like one too.
Thats some great numbers, congrats.
You gotta be stoked to have that beast headed your way

Ive been stoked for the past 1.3 years

Man, its been a long time waiting, but it sure as hell will be damn worth it.
I mean realistically, its a brand new car.
new motor
turbo kit
tubular k member
weld on sub frames
rebuilt tranny
new 12 bolt
He has surpassed what I had asked from the get go and I am very pleased with the setup, despite the wait.

Yes, I read my spark plugs and the last set looked like a perfect burn, my car is tuned 11.0-11.2 and then I add meth on top of that for higher boost.
My car makes very little smoke tuned in the low 11 range, not even close to a diesel. If I run low 10's/9's a/f I get some good smoke though.
The reason for tuning on the rich side is it has very little effect on power and provides a lot of extra cusion fuel wise. Tuned 11.8:1 there is very little room for error. I never let my car go leaner than 11.5:1 on race gas. If it's tuned for 11.0 it will lean out to 11.4 if the gas i'm using has a really low specific gravity.
I'd like to see what this thing does on 20 psi

My car tuned 11.0 on the street in 4th gear will read 10.6 on the dyno. I've tuned several cars on the street to 12.5-7 a/f and had them dyno 12.2-3 on the dyno. N/A cars are not affected as much as turbo cars are is what i've seen.
I've also played with a/f on the dyno with my car and from 10.5 a/f to 11.3 a/f I only got a 15 rwhp gain which really surprised me, but I've repeated the results on a few other turbo cars in town here.
Sorry for the hijack, but I thought I had this figured out, and now I'm reading the opposite of what I thought.

However once I get all the paperwork sorted through ill post up all mods that have been done.
lets just hope ls1tech's bandwith is large enough


.....sweet setup too. That thing is going to be tough. (make that IS tough)
