Well went to the dyno today for the first time since the new turbos went in. Some VERY impressive results.....however late in the day I developed a MAJOR boost leak we couldn't find. SO it was short but we did manage to tune with the Motec A/F computer So anyway....we tuned at 15 PSI....made 416 RWHP and 401 torque @ 14 degrees timing. It was interesting....we richened it up 4% at 3000 and 4000 rpms....then leaned in out 6% at 5000...... Then we turned the boost up to 17 PSI and made 452 RWHP and 468 torque....NOT bad at all.
So next we set the BC at 1.55 bar and WAMMMMOOOO.....no mo boost. SOmething came off somewhere....as we were not able to hold but 15 PSI and it wanted to drop down to 10 PSI....major leak. Too bad as Im sure I would have met my goal of 530 ish RWHP Tommorrow Im off to Greg D's to figure out whats up. Then Thursday Ill make a nice clean 25 PSI run and see what she will do!
