25947, Dyno results with 26psi
Posted by Greg, Jul-08-02 07:57 AM
340hp and 300lb/ft of torque is all we could get outta it for now. I was a little scared so we pulled like 8 degree's of timing and ran her around 11.5-12.0 on the wideband. I know if we give some more timing and a leaner A/F mixture I should be closer to 360-375HP. I guess well have to see in a couple weeks when I go back :-D.

...that is just sick, and you were running rich with a lot of timing retard. I think you should be able to pull way more than 340 though, we'll see...

Good god, 26psi! Lord knows I don't have the balls to test my car that high. Very nice pull though!
How much advance was the ECU running at WOT before you pulled the 8 degrees out?

BTW, Did you pull any timing when you ran your 12.8 et??

Very good numbers! 26 psi, wow! Have you ever driven on the street with that boost?

This is some datalogging I did. These were done in 3rd gear at WOT. These #'s are what the ECU see's not with my retard added in.

RPM Timing
3250 30
3415 31
3634 28
3875 29
4144 27
4458 27
4734 27
5042 23
5309 24
5591 25
5852 27
6093 28
6314 26
6520 25
6737 25
6920 25

I did a few 3rd gear pulls with 26psi right after the dyno and could get 0 traction and 4th gear takes me to 130mph :nono

damn nice run. im betting you could get up close to 380 or so with a leaner mix and timing retard. i need to get to a dyno sometime and make a run at 20psi.

interesting 26 PSI sure is a lot though cuz 5 psi makes like oh about 60 HP no X5 it should be bout 300+ that 1 psi and that's like 130 ( hehe it somewhere aroudn there on the crank) making it 430 HP. That sounds about right I suppose if you tuned it a little better you can probably hit 400. Haha don't go blowing up your engine now...
