Dyno'd my car today.
I did some tuning on it and got 345hp and 355tq. I would have thought I would have gotten more.
I know I need a larger tb and the cam is for a supercharger (see sig). I want to change the cam to a 847. What do ya think?

What kinda changes did you make on the dyno?

I also read that the 12 bolt and 4.10 will soak up about 7% in drivetrain loss, so that would bring up to 369hp and 380tq.

Re: Dyno'd my car today.
Are those just stock lt4 heads? If they are you really need to get some ported heads on there. And yes you could probably pick up some more with a cam. Stock tb might also be restriction you but not nearly as much as stock lt4 heads would.

But for this thread and what I have to work with right now, I would have thought I would be running more.

Re: Dyno'd my car today.
seems kind of low, a few people I know with fully forged 355's are making 400 rwhp NA, but the also have different heads and cam setups. With a forged 385 I would expect over 400 to the wheels

Re: Dyno'd my car today.
You probably aren't gonna get to much more out of it. There was a guy with a LT4 97 firehawk on the board and he added a cc306 and headers to his stock headed LT4 and only put down 360ish. You're cam isn't as good as a cc306 either. Why are you running a blower cam when you aren't gonna go with a blower? Your compression ratio is way to high for a blower.

Re: Dyno'd my car today.
Those numbers are extremely low even with the cam that you have. BTW, no way in hell are you losing an extra 7% drivetrain loss at your hp level because you have a 12 bolt. It may cost you 7% if you are only putting out 100hp, but definately not with 345hp.
