So here is the before and after dyno #'s

This is with only 17 lbs and NO METH on 91 octane. We will be switching out to a 88 T crank pulley and a larger intercooler from bell this fall. Shooting for 1100 to the tires.

Here are more pics.

Here is the engine dyno graph. This is without the supercharger. Not to bad for low compression and a boost friendly cam.

Here is some pics of this car in our booth and this years Camaro 5 Fest.

Wanted to let everyone know that we are offering what we did on the car as a package deal and can even offer a 3 year limited warranty on it as well.

Feel free to call or PM me with any questions.

Nice work Mike and Mark!! And to think, you did all that in just three weeks!! Unlike other shops in the area. RMCR, you do great work!

Mike@RMCR · 06-27-2011, 04:23 PM

It was brought to my attention that the dyno graph was in speed. Here is one with RPM.

taz · 08-25-2011, 12:22 PM

Ive never had a cog drive on my supercharger. Is it alot louder than belt drive? With that kind of power, figure you had to go cog drive to eliminate belt slippage.

Thanks

jrpxxii · 08-25-2011, 03:36 PM

Yes a COG drive is louder but in a good way as it screams at you. You have to COG drive for more boost and to eliminate belt slip.

Why a 9.6:1 compression? Most builders are using 9.1:1 on an LSX 427ci. with boost.

My understanding of this is less compression equates to less power / heat, but more boost to make up the power loss.

I dont like going lower on street cars. This way the car still has a good feel at lower RPM's. I have never had an issue running them here.
