Went to the track again last weekend with sad results....13.17 at 99 on 18psi

Mods are .030 4.3 L35 heads, stock intake, 75lbs injectors, 412 cam, log manifolds, 58mm turbo, 3" downpipe. Art carr convertor.built 700r4. Stock gears and tire sizes.... Just seems like it doesnt run like it should....I think it needs tuning help more than i can give it....

Any help appreciated

Re: Whats wrong with my setup?

what kinda 60' did you cut? Whats the stall of your convertor? Are you locking it?

More details on the turbo? AR size?

Re: Whats wrong with my setup?

biggest question should be the tune. Then converter size and 60' times

What does the run look like on a scan tool, any knock retard?

I am not quite sure what your running for a turbo, beside its 58mm, but ti still would expect better than your times.

Its a 10.5 convertor. 1.90 60ft, the convertor stalls 3800 in boost. The turbo is a T4 garrett with a .81 A/R thats all i know about it. No knock retard that pass

Its seems like a lot of stall, but I am not 100% sure on that. You should be doing better than 1.90 60' Whats your transmission shifting at? What do use for a chip? How are your Intake tempratures?

Shifting at 5200-5400 my 60ft kind sux as im not used to the building boost on the line yet....The chip is/has been burned by my and the previous owner...Intake temps are about 130-150 on that night. Seems like im doing the least with the most.

What are you tuning with? Sounds like it's all in the tune... maybe a good time to do Code59 if you haven't looked into it yet.

Yep, your 60ft is not good at all, and MPH is showing stockish HP level. You got a WB installed you can monitor?

What timing are you running. What gas are you using? Your stall is to much for your cam and turbo. How far down the track are you before you hit 18 lbs boost on the data log?

I had my MT2500 scanner on it...I can data log with that but only the sensor outputs.

What kind of fuel are you using? You really need a good datalog setup.

Re: Whats wrong with my setup?

get a cheapy laptop. get datamaster on it, with dig's wbo2 patch. youll be able to monitor better then the scan tool you got. but with ur combo, you show be going alot faster then that.
