  • Dyno Numbers for the 88' TGPSE

    First I want to thank Lorenzo and Adam for helping me with all the work needed to bring this car to what it is today. I could not have done it without the garage space and time volunteered by Lorenzo to help me select all the right parts and install most of them on this little beast. And thanks to Adam for all the tuning help and stuff on the boost end of things.

    Anywho we went to a dynojet outside Scranton, PA. Not the most how would you say organized shop by any means (multiple issues just getting on the dyno and once we were on there the WB on the dynojet was measuring 16 AFR as compared to my LC-1 in car reading 11.5-11.9 AFR) but once we DID get setup they were super cool and let us do many more pulls than originally stated. Ended up doing 8 pulls for $120 basically had the dyno from 1:30-5pm to dyno and tune. So mixed feelings but probably would go back again since they were easy going about it all.

    Basically the car was running strong in the morning but Adam wanted to add some timing.......so on the way down we stopped and reburned a few times.

    First pull was 251 hp and 297 ft-lbs at 14 psi. Not bad I thought out of a little 2.8.

    Well look below for the final numbers.......I'm sure there is more in the car, exhaust was limiting boost to 14 psi so need to free that up. Mods are in my sig......I do have LS1 valve springs in there as well.

    Car feels great! Lets see how long it lasts!
