I'm sort of interested in doing one, even though I don't feel like driving to Atlanta. I didn't do one prior to installing the CBE/HFCs, so I'm not sure what good it would do the community.

Yeah having a baseline would help. Don't waste your time/money.

C'mon Berk group buy people. Y'all made enough noise in the last few weeks, step up and get er done.

Oops, missed this. Yes, I am. Putting my setup on today. When I'll get to dyno, not quite sure - fairly soon. Probably in a couple weeks.

You have baseline numbers already? Say yes, lol.

I do. Unfortunately, I think the dyno got a terrible read so my graph is flawed :-p. But, it looked like I put down the normal 275ish that everyone else puts down on Dynojets.

It was my torque that was in question...

I swear, unless you go on a dyno, do a baseline, then furiously put on a modification, then run another dyno all in the same morning, you can't get a reliable read for gains.

Dyno's only measure torque, HP is calculated.

But basically you're saying that the middle of your graph is screwy and so you may have not got an accurate peak torque measurement?

Well, right. Basically everyone peaks HP somewhere around 7K and it levels off. Mine was supposedly at 7.5K and still rising, and I barely hit 275. Dynojet only registered 205ish torque or so. So, something didnt seem right. Never did get a response from Altered Atmosphere on this...

HP is calculated (continuously) as Torque * RPM / 5252.

So if your peak torque measurement is low then there should also be a dip in the HP curve between 4-5k rpm. The torque plot and HP plot always cross over at 5252 rpm provided they are plotted on the same scale.
