My car dynoed a 189.4whp on a hot day (corrected). Though I suspect the car has more but because of the SRI it only show this number. Another reason I suspect my car has higher number is because I've raced a modded type S (apparently i/e, don't know if he has header) and I walked all over him. I know someone who has i/h/e put out a 183 whp, he dynoed his car the day before I dynoed mine, so his number could also be affected by the temp.
