dyno'd my coupe today.
 

all stock. 2800 miles, 2004 6MT.

1st run 4th gear. 230 RWHP 228 RWTQ
2nd run 5th gear 233 RWHP 233 RWTQ
3rd run 4th gear 234 RWHP 233 RWTQ *10min cool down time*

could i have hit 237rwhp if i did 5th gear on the 3rd run?
judging by other dyno's i can say i am quite satisfy with my results.

this was done on a Dynojet 246c i think. on the same dyno i ran my integra GSR years ago stock to 138 FWHP. which most integras run 144 to the front on this type of dyno, which i thought this dyno machine might be off. but from running my G35 in it, i guess the problem was my integra??

Can you please explain why you didn't use the 3rd gear?

using 3rd gear on a 6spd car would make it way off. you want to use a 1:1 ratio gear to determine the power. 5th gear is 1:1 but 4th is most likely used. but 5th should be used on a 6spd car, 4th on a 5 speed car. get it?
