Out of curiosity, what do they normally put down?

Also, the file for Joe W. seems corrupted on the ImageShack server. Anyone else see that? Look at his A/F!!

 

goldenfri's looks to be running a little lean, no?

 

He's also putting those numbers down without the aftercooler.

 

That means he's running more boost than you will. The aftercooler loses about .5-1.0 psi. With cold temps though, he wouldn't have needed it yesterday, but the numbers are about right as a Comptech is good for about 80-90whp.

 

So if we dyno again in the summer, the gap will widen back to where it normally would be? Jim dyno'd just as well as Jorge who is running the aftercooler which seemed odd to me even with the cooler weather. I did not realize that you lose boost with the aftercooler either.

 

Yeah man, 522 ft/lbs of torque is aight...I was hoping for a bit more.

 

Yeah, you lose a bit of boost with the aftercooler due to the extra piping. Congrats Jim! He made 289whp with an exhaust and stock cat. I made mine on a test pipe.

 

I would have liked to see the rpm's run along the bottom of the graphs instead of speed. Thanks for the nice day, Peter!

So the question remains why there wasn't a larger gap between them. Where is the incentive to run the aftercooler if the gains it nets you are offset by loss from losing boost?



I think I need to head over to the FI forum and read more old threads about this stuff.

 

Jorge: test pipe and the aftercooler = 287 peak
Jim: no aftercooler and stock cat = 289 peak

Even more now...
