so my friend just got his gsr tuned and his numbers were pretty surprising.

its a stock bore and crank gsr with itr pistons
stock head stock cams and skunk2 IM with 68mm throttlebody. 4-1 itr ebay replica header
tuned on crome. 137tq/182whp

when I had a similar setup I made 184whp/127tq
81.5mm b16 pistons gsr head skunk2 IM 68mm TB and buddyclub spec3 cams with try-why replica and full exhaust

I was at 137tq when I hit 200whp after upgrading few things.


but im looking at in@rr numbers they are all different..

just wondering if its something to do with engine ( both were fresh rebuilt) or tuner tweaking the dyno numbers to make him happy

Depends on what the torque curve looks like. He might be producing torque early and having it fall off, which would explain the 137tq and 182hp. The lower you make hp the higher the required torque to produce that power

oh yea lol I forgot I had a massive breakdown from vtec to about 7000 rpm then it was smooth...
his torque peaks at around 6500
mine peaked at 7400 because of that weirdness between 5800 to 7200 rpm it would be higher than 137 if it went normal curve and not dip down
