Aight so I got this JRSC manifold for an ITR laying around, I might just pick up a used blower and the tensioner puller and relocation bracket, and have the teg supercharged for very little money. I have been looking at an M90 blower, it flows more than a M62 and it has the same bolt pattern as well. Its 12mm wider not from pass side to drivers side) than a M62, and 13mm taller. heres a pic to show you:

anyone with JRSC, how much clearance do you have to be block/head? i think with an M90 it should pull quite well, it flows 550cfm opposed to 450cfm the M62 pushes.

I have looked into this extensively. Here are the problems you will run into. Jackson racing hold the patents for the counter rotating nose drive. so first you have to get over that hurdle. Next the distance from the center of the drive pulley to the first set of hole that bolt it to the manifold are longer so you will have to shorten the nose drive or modify the intake manifold because your blower nose drive would be into your shock tower. Next you have the issue of the oil filter. You can fix this pretty easy with a relocation kit. Lastly to do this whole thing you will have to install the blower on the engine off the car and then stick it in the car. this is because of the clearance between the blower and the intake manifold to actuall get to the bottom manifold bolts to tighten them. Now if you are really considering doing this do it I would love to see the Huge numbers that this setup would put down. @8-9 psi on a gsr motor I would believe 300WHP is a very easy goal.

damn I didnt even think about the JRSC rotating counterclockwise. I really wanna do this but I dunno how I will overcome that...

i wonder.....assuming, say, 8 psi on the m62 and m90, if the charge temps are the same, or if the m90 would be more efficient and produce lower temps.

<edit>i checked the charts and it looks like temps would be the same

This sounds awesome, leave it to JR to screw it up with a patent!

BTW - any of you have a 6psi (4") nose pulley you want to sell or trade for my 8psi one?
