So heres the deal. I went to go dyno my sr this weekend at a local shop here. they were having a dyno day and i was the first one to dyno my car that day. last time my sr was dynoed (at the same shop) it made 203hp/205tq on a dynojet with the stock t25, 11psi, fmic, intake, dp and exhaust.

This time it was dynoed with the following upgrades GTiR T28 @ 18psi, enthalpy tuned ecu, sti injectors, a greddy elbow(had stock one last time) and my car dynoed at 211hp/207tq.

Everyone i know thinks that is bs. my car feels a whole heck of alot peppier. and ive Almost cut a second of my 1/8th mile times(8.2@87mph vs 9.0@75 or so) i was told by scott at enthalpy that it should be making close 300whp.

so i went and took the car for a couple pulls once i got off the dyno and it feel as strong as ever. the next car to dyno after me was a stock s2k that made 195whp, which seems dead on.

Either something was seriously screwed up with my car for those 3 pulls or the dyno was wrong. I dont know much about dynoes but i think something was up with theirs. the shop guys werent even attempting to help out, i guess they were too busy or something. does anyone know if a dyno has to be calibrated or something before a car is dynoed. either way, i think im going to give them a call monday and try to work it out.

 

Going out on a limb here since I'm completely new to the S-chassis and don't know exactly how these cars react to upgrades, but could it be an increase in area under the curve that you gained? Not much of a peak gain, but gains in other parts of the curve? I'm probably wrong here but coming from an american V8 im used to looking at gains under the curve more than peak numbers.
