I am not sure that most folks understand the amount of experience and knowledge both Tom's posses. They have done more then we will ever do.
On another note we have an engine builder down in Texas that installed a Procharger D1Sc on a 462 Pontiac build. Spinning the motor to 5300 rpm, with an 8:1 compression ratio, at 7 lbs of boost with a Sniper EFI it made 610 ftlbs/600 Hp. This had E-heads. Based on these numbers it would be a similar outcome.
With that said the boost is very consistent as far as boost pressure and power gains in the Pontiac engine platform.
As far as centrifugal (belt driven turbo) supercharger compared to a exhaust driven turbocharger system, the supercharger has many benefits:
1. Ease of installation (A customer can bolt this kit on in 1.5 hours)
2. Can utilize existing headers and or exhaust system
3. Can use a BT carburetor versus going directly to fuel injection
We have been working on a turbocharger system with "cost effective" manifolds. Even in this case the development cost and time to make a complete ready to bolt on kit to date has doubled the development for the supercharger kits. And it is still not a reality yet.
We won't give up but we also will not compromise the cost factor as well as the quality and reliability. Stay tune...it is going to get really interesting in the "boost" world for our beloved Pontiac's! 
If anyone has a question please feel free to ask on this thread or call or email us. We have nothing to hide and there is no black magic, just good ole physics in play. |
It wasnt you Mark. I miss read it. When i saw 22--26 i thought you were going to go higher then 13 psi. Plus i really thought with the smaller runner size that it would go higher with the boost then last time .. 750 pounds of torque from a 4" stroke is unbelievable ! Great job! Thats alot of torque for a street car.Would love to see you go 20 psi with it one of these days though.. haha..
Good luck with what you're looking too achieve..
