I hope they figured out another way to get better belt wrap.... But they got the impossible done with the injector bosses.

Umm, I just checked out zzp'* site and I see nothing other than mention of the M90 kit as "Coming Soon". :(
Anyone have a link to the pics?

yeah 95naSTA, like you said in there...

there is gonna be crazy belt slippage with that setup...

there is only like 3" of belt touching that fat *** pulley...

chain drive

still cool as hell though...

besides loss of performance, what are the other negative aspects of the belt slipping? that would scare me if i heard it fly off when i was cruising down the road. kinda funny in a way too, like a jacket being zipped up.

i wouldnt be worried of it slipping off that pulley..that thing is like 4 times wider than mine!

belt slip is just gonna kill ya in performance...and its gonna chew the belt up

It might be a cheap kit, but it looks like a lot of work installing that thing.

nice setup there
about the belt slippage problem i've been toying with an idea but i am wondering if Mr Intense/ Intense has thought about using a 4+ inch dia SC pulley with a planetary gear settup to stepup the SC shaft speed.
the best of both worlds no/minimal belt slippage and the associated power loss,
as well as being able to gear the SC at 2-3 inches diameter equivalent overdrive for great low end boost or gear it for high rpm boost.

I started playing with the idea when i was rebuilding a chrysler 413 3spd FWD tranny and one of the planetary setups behind the forward drum looked perfect for a 2:1 steppup ratio if adapted right. these are probably even more compact and efficient planetaries out there of course.

two developmental isues would be the bracket for holding the ring gear still, while the belt can drive the planets to overdrive the sungear (SC)
the other is sealing/lubrication having a sealed design is probably a little creative work with an o ring or two.

centrifugal supercharges have been designed with similar planetary overdrives to drive the compressor wheel, one of these may be a perfect solution.

I am curious though if this has been worked with at Intense, would be one of the best ways to improve an eaton setup.

That sounds really interesting but i'm not 100% clear how it would work. Could you draw something simple in paint to help me understand better?

here'* a real simple drawing but it should get the idea across

http://img.photobucket.com/albums/v4...drivesetup.bmp
damn i cant get the pic to work but hope the link works ok

any twisting loads caused by the belt tesion pulling it to one side will be negated by driving the planet gears by ataching them to a pulley that will cover the ring gear (remember it'* atached to the SC snout/case-some creative brackets or tig welding a plate at the corect spot of the snout to bolt the ring gear to) and place the belt load directly on the ring gear (in axis eith the planetary)
I wonder if i could get a CAD file from Eaton and play with it some
strength is not a huge issue as the supercharer couldnt take more than a reasonable amount of torque to spin twice as fast
I need to play in Cad to see what options for sealing the unit (or dry lubricated/grease fitting lol)
i still wonder if Intense has thought of this, i mean it can be something i could make (my plasma cutter/MIG-and my buddy'* Bridgport mill/TIG) but i would think that Intense would be able to pull it off and make it look nicer lol
