the motor's pretty much stock except for a k&n filter and a single pipe 2 1/4" exhaust, which is more restrictive than stock. these numbers are after light tuning with an s-afcII. i had some miss or break-up past 5500 so...

hp: 109 @ 7100rpm
tq: 101 @ 3700rpm

wait for the rb road/race header and no cat numbers...

 

those numbers are pretty low even for a stock car, what dyno was it?

 

5th and 6th ports are probably stuck or something.

 

it's a dyno-mite chassis dyno.

up past 5500rpm i started to miss really bad, i haven't tracked it down yet. i'am throwing a pressure sensor code also. so, that's got to kill the numbers a little bit.

i know the exhaust is cutting it down too. i'am putting together an exhaust made up of a racing beat road/race header w/ extra long primaries, then y'd into a 3" pre-silencer, then y'd back to two mufflers. it might sound iffy, but we'll see what it makes.

oh yes, i believe you are correct about the 5th and 6th ports sticking. the rear port particularly.

anyway, i'll get that stuff fixed (hopefully my lm-1 will have gotten here by then) and then we'll see what it puts down.

i will also be removing the front plates off the throttle body and then porting it... should be fun.
