I don't know how to post pics too well yet, but has anyone seen that new roots style SC from KB that goes on the side of the engine near the battery? I found it on that "dragonrace.com" site. It looks very cool!

I'ver seen it also, but I am going to wait to see what kind of bugs they come up with. It looks very interesting and they say that the numbers are very good on the stock C6

KB isn't roots, it's twin screw. Twin Screw is more efficient than roots and has less parasitic loss. KB has ability to make 800+ hp with forged internals whereas Maggie (roots) tops out at about 500 rwhp.

Well now you got me confused, I thought that any SC that was like the maggie was a roots?

Nope. Three types:
1. Centrif: Procharger, Vortech, Novi
2. Roots: Maggie(new Shelby Mustang has roots)
3. Twin Screw: Kenne Bell(Ford GT has twin screw)

See link for more explanation.

Shows what I knew! Exactly what you thought, well you do learn something new each day!!:D

forgive me for my lack of knowledge on this subject but doesn't the Maggie have (2) screws inside that spin around?

Go to the link below and you will see 9 sections that you click on sequentially to get a got overview of the specifics of SC and the various options. Below I excerpted the relevant language to answer your question:

"A twin-screw supercharger operates by pulling air through a pair of meshing lobes that resemble a set of worm gears. Like the Roots supercharger, the air inside a twin-screw supercharger is trapped in pockets created by the rotor lobes. But a twin-screw supercharger compresses the air inside the rotor housing. That's because the rotors have a conical taper, which means the air pockets decrease in size as air moves from the fill side to the discharge side. As the air pockets shrink, the air is squeezed into a smaller space.

This makes twin-screw superchargers more efficient, but they cost more because the screw-type rotors require more precision in the manufacturing process. Some types of twin-screw superchargers sit above the engine like the Roots supercharger. They also make a lot of noise. The compressed air exiting the discharge outlet creates a whine or whistle that must be subdued with noise suppression techniques."

Well now I know! Thanks for the leason in SC:D So what kind do you have on your Corvette?

I have a Procharger D1SC(8 rib set up) with a forged bottom end, patriot cyl heads, ESC fuel pump(required to make hp over 600 rwhp) and 100% alky kit. The car puts out 740 rwhp on a mustang dyno which is about 775+ on a dynojet. Engine hp is approx 850.

My SC, which is a centif type, builds boost exponentially, so it doesn't really come in until the car is around 3,200 rpm. The Kenne Bell and Maggie generate torque at low rpms. Because I am running 16 lbs of boost and have a small sc pulley, I start generating boost and therefore torgue earlier than most typicaly centrif blower set ups. Those, at 8 lbs of boost, don't really kick in until 3,800 rpm.

LOL Tom, I was just about ready to ask you what kind of a SC you had?

I wonder how it will handle the heat seeing that it is right on the side of the engine closer to the headers?

I spoke to the owner and lead mechanic of dragonracing about two months ago. They have also just finished with a (3.6 I think) Whipple twin screw blower for the C6. Horsepower was in the 600+ range on 6lbs of boost.

Yes I have looked at that SC, it seems very nice and is 200ci (if I'm correct) At almost the same price as all the others I would go with it as it will most likely produce more power!:D

I called Dragon Race up the other day and apparently this new set up is putting down about 50 more hp than the maggie and at the same boost!!! THats pretty nice in my opinion!

I am ordering the Magnuson 122 this week coming up!! I am soo pumped!! This is my first mod and I went all the way (so to speak) I will let you all know when it is completed!:D

Cool! you're going to love it. If you need any help with it give me a call, we work on a lot of Magnuson's and are a direct dealer, so we can get you through just about anything.
