I am not in active practice any longer and haven't been for a couple years now, I think Randy is just tired from our out of town install we did last night and the fact that he got home after 1 this morning, I am sure his usual non cryptic self will return soon

As for mine, well...

He's not...During the day he is the president of DDMWorks...At night he is the lead engineer at DDMWorks

Yesterday was only a 16 hour day for him. I had a total of 20 hours yesterday

Ok the Sky is on the road, and OMG I did pick up 1.5 pounds of boost and at WOT I am at 10.5. I have to be very careful need the clutch to last...Now I need my wife to let me play with her turbo Sky .seal9

If you work out the pulley ratio's they end up being the same as the old stage 2 setup, just that with the new setup there is little to no belt slip anymore so towards the upper end of the rev range when the engine can not breathe the air the supercharger is supplying, the boost starts to rise.

Obvious next question...what has to be "freed-up" to allow the engine to benefit from the more efficient air delivery? Are we talking head work at this level?

So, maybe things become Stage IV in the future…?!?

Ported head & larger valves; or, fresh ECM retune that works the VVT…?!?

Or both…!?!

Maybe 400whp for Stage IV…!

There not telling, just hint around.

Back on topic. Went stage I at 12k, stage II at 20k, going stage III at 32K. Cold facts:

stock: 0-60 6.8 seconds, 16.8 seconds in the quarter
StageI: 0-60 5.7 seconds, 14.1 seconds in the quarter
StageII: 0-60 4.7 seconds, never got to the track

I still run the goodyears and stock clutch. On cold roads I cannot hit it hard in first or second, but I can roll into the gas. Slapping the gas will induce severe wheel spin and smoke - lot's of fun if that is what you want.

Issues: I was a belt thrower, 3 times infact before I got the modified system. Haven't had an issue since. Next month I will get the 3 belt setup with the Stage III and I am told I will be seeing around 12-13 lbs of boost, A new clutch is going in at the same time.

I expect I will be needing tire before the summer is over
