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.

Nice!!!

25951, WOW... Posted by Skrilla, Jul-08-02 09:25 AM
...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...
