I have a with a 935 motorsports y-pipe/downpipe, afc neo, old school hks bov, greddy profec type s (wasnt installed as the time of the dyno) running 10 psi boost, and my car put down 236hp and 244tq does that sound right? sounds kind of low to me
Here is a pic of the dyno sheet http://myspace-381.vo.llnwd.net/01267/18/30/1267490381_l.jpg

236 is an awesome hp rating. Especially if you have an n/a wich you don't.

So you should be around 300 to the 350 range IMO.

i wasn't there but just by the dyno it looks like you were a little lean on the fuel which is not a good thing (no shit dizahl) the profec i'm sure helps but i would really keep an eye on your a/f ratios you might be able to squeze some more ponys there.

yes it was running lean at first, i think it was at 14 afrand then we tuned it down to a 11 with the afc neo. I was thinking it should be higher but not that high, i was more thinking about 240 or 245 with tuning.

dude a completely stock 1jz puts down about that same hp on stock boost, something's wrong somewhere.

one of my buddies has an rx7 with a 1jz. the only thing he has done to it is standalone fuel management. after market BOV, and a bigger turbo. he was running 16psi with out the standalone and he was hitting 330 to the wheels with like 316 torque. they are rated at like 370 crank stock so that 245 you were hitting there has to be something wrong. and with his standalone and running 20 psi hes hitting 376 to the wheels but not sure about the torque
