RJ MFG Supercharger kit Feeler...

Thats what im thinking

-But does reducing the number of laminova cores lower the overall height a bit?

RJ MFG

no it does not. we will supply blanks in the location of missing cores. Saves you money in the event you want to upgrade.

Will you take sexual favors in exchange for one of these systems?

Ok thanks for that - When will you be announcing the various stages and corresponding power levels?

I wouldn't expect any stages and pricing for several weeks. RJ MFG is working with laminova directly about the intercooler core. the design there isn't finalized and that will affect some of the other parts. I can say they are looking into mezeire (sp?) 55gpm pump that has a 3000+ hour pump life! That's a huge leap up from the bosch pumps stillen uses. Also after reviewing the cooling capacity I believe they have decided to stay twin pass on the heat exchanger.

The current idea is to run a 4" crank pulley and a blower pulley ranging from 4"-2.5" for stage one. Now the stage 2 guys I think they are bumping the crank pulley up to a 5"-6" crank pulley. So far I believe they are trying to limit the drive ratio to 2.0. At least for those looking to rev to 8.5k-9k. If you stick to lower revs you can get more of a drive ratio (2.4 if your stock rev limit).

It's definitely going to be interesting to see what they come up with. But if I had to guess I would guess that the price per hp will be competitive. The stillen kit is about $19/whp averaging 420whp on 8psi. The GTM/gamma kit is more expensive at $22/whp averaging 410whp on 8psi. This is based on their retail pricing. So if RJ MFG are able to make 450-500whp on 8psi they would be competitive pricing wise with what they have stated thus far.

I am stoked!

500 wheel @8psi would be mega - Dont think thats out of the question with a 2.9L unit, hopefully torque will also be close to 500ft/lbs.

Stage 2's 600whp @12-13psi anyone?

I think most are looking for flat or at least linear, increasing, torque. To make 500 hp and 500 hp, you will have peak torque before 5252 rpm with a sharp drop in torque after that. You only need 350 ft/lbs at 7500 rpm to make 500 hp.

nice correlation of torque and horsepower.. rare to see an understanding of that. while this blower makes instant boost, it doesnt make instant full boost.. at least it doesnt tend to in the applications i am used to watching it work. on my coyote the boost somewhat ramps in, so the peak torque can occur some higher and stay flatter.

but i still dont think we will see this blower make both 500 HP and 500 torque from the same pulley, probably going to have to pick one or the other. 500 torque is too much for the stock engine for 90% of users IMHO anyway... reserve that much for the risk takers.

heres the whipple 2.9 in action on my coyote, which as a 11:1 v8 DOHC. not all that mechanically dissimilar to a VQ + 2 cylinders. Notice the boost curve. I bet if you take the numbers and multiply x 0.75, that is probably rather close to what you could expect to see in VQ performance with it.
