welp, time to face the music. i haven't scanned the sheet yet, but the numbers were.... 255 rwhp, 300 rwtq. owie The curve was roughly where you thought it would be... pulled until 6000 with a peak at 5800. However the torque curve peaked really early... about 3500 there's a spike and then it falls back... the owner of the shop was somewhat surprised.
however, there were some easy fixes (well, some of the fixes are easy). One, its running ridiculously lean. About a steady 14.5 AFR after 2500 rpm. If I get that down to 12.5-13 with a new jet kit, that has to help. Also, the timing still isn't right... the dyno shop owner said he could tell it wasn't idling right and didn't think it was advancing far enough once it got rolling. I might need some sort of more accurate distributor etc.
One other minor thing... the parking brake was on
Which was the final issue, and one that can't get fixed quick... it is burning a ton of oil. Right now it has some high mileage synthetic blend stuff in it (10w30)... I'm goign to have to change that to 10w40 pure dino oil, because the amount of oil burnage was ridiculous. Kinda bummed about this because it wasn't going through much if any oil very long ago, really hope my heads don't have a messed head gasket or anything and its just a worn out block. Hopefully heavier oil will slow it down some. Can't imagine this helps with compression either.
In any case, I'll be tuning it and going back, hopefully with slightly better results.
One cool thing... there were some pretty mean cars at this place. The owner had an AWD 07 or 08 Trailblazer SS that had a Vortech on it making 600+ to the wheels, and right before my car he dynoed C6, also supercharged, that put 509 to the wheels and he was disappointed with it.
So yeah, I suppose 68EFIVert owes TD68302 a 6 pack. Get on that
