so could you guys help me out.i wanted to see if anyone had a similar setup to me or if some of you gurus could do a good guesstimation on how much hp and torque im possibly making at the wheels.its a pretty simple setup nothing spectacular...i have..

stock bottom end & untouched stock heads
comp cams xe 230/236 112
crane 1.6rr
k&n cai
ebay headers and y pipe
"flowsound" muffler & electric cutout before axle
pcm has been tuned

what kind of hp and torque u think im making at the wheel?
thanks

 

A4 or T56? Do you have a bigger stall converter in there and a bigger rearend? Id guess if its an A4 its in the 330-340 range and if its a T56 340-350rwhp. Pulling the heads and putting in a impala head gasket will bump the compression up will help alot.

 

car is a 96 z28 m6 with the stock 3.42 gears.i just want to get a "idea" on my hp range.and then maybe try to max out the power as much as i can before i start touching the heads and shortblock

 

You will be better off if you can get to a track and follow your improvements there. There is no standard from one dyno to another and your car can show different readings even on the same dyno depending on who is running it that day.

 

Without any head work,I would guess your around 300 rwhp..

 

I would guess that as well if it's healthy and assuming good valve springs.

 

should easily hit 330rwhp with mailorder tune. Squeak a few more ponies with a dyno tune.

I made 383rwhp/353rwtq with the same cam and a set of LE2 ported heads done 8-9 yrs ago. I was on a mailorder tune that I tweaked the A/F on.... never tweaked the timing.

 

Didnt 96 M6's come with 3:73 from the factory?

 

'93 - 3.23
'94 and up - 3.42

 

Actually 93 M6's came with either 2.73 or 3.23. After that, all M6's were 3.42.
