Contour Enthusiasts Group Archives Forums Modifications Forced Induction Roots S/C on Duratec?

Kenne Bell uses Whipple superchargers in his kits. Whipple twist's the rotors in the blowers on a much steeper helix than Eaton does, However Eaton superchargers are also a twisted helix design only not as much twist. Hope this helps.

oh yeah... lol, that is where i read that about the kenne bell vs eaton.

i was gonna say the same thing about eaton being rock solid as far as reliability...

still... the kenne bell unit does run considerably cooler then the eaton does at the same rpm.

I couldnt agree with you more about rock solid durability of the Eatons. They are solid as a rock, thats why I like them so much. 3 of my freinds put whipples on their vehicals, 2 PT Cruisers and 1 Chevy dualy truck. All 3 had some pretty sizable issues with there kits that took several months to work out, and the Cruisers are still having some small problems. I'd rather not go through all that. So for me its Eaton.

Thats to bad about your buddies SC install. He should have gotten a kit from Endyn, there cheaper and from the sound of it create far more performance than he got. [/QUOTE]

That would be nice except that ...

(a) there is no such thing as the Endyn supercharger. There's only one, hand built prototype in existence, on a 1989 Civic si 1.5 SOHC. It's a monster though.

(b) cheap is relative. All the bits n pieces to support a 400+ whp FWD car safely will easily run you $15K (trans, brakes, suspension, etc).

(c) some other dood on the Forced Induction Integra board sent his entire engine + Jackson supercharger to Endyn to build it to hell (forged pistons, pNp head, Eagle rods, reworked Eaton SC, etc. Long story short: At 17 psi and $10K later, it barely runs better than it did at 11 psi.[/QB][/QUOTE]
(A) I never said there was a Endyn supercharger. Larry uses Eaton superchargers in his kits, of course he does some work on them. The prototype you refer to is one of Larry's testmules its a car not a supercharger, there are several other testmules as well. (B)Thats interesting. {C} That dood on the Integra board should contact Endyn and express his displeasure with there service and products. Endyn has a policy that if your not satisfied and there products dont perform as advertised you get your money back. I've never had any problems with them, but then again I'm just one person.

Huh..the T-bird SC's are pretty cheap if you go used. That might be a viable solution if fabricating the brackets and other materials is available. I am still going to assume that hood clearance would still be an issue.

take a look at the cuogar eliminater it used a roots blower mounted were the battery is with a custom adapter. and that was on a 3.0l as well.

uhm... a roots blower bolts on to the lower intake manifold and runs directly off the FEAD... how could u put it anywhere but "on top" of the engine?

I thought they can go anywhere as long as the drive pulley is aligned with the crank. By having it over near the battery does not sound like it's near the crank.

I was just going to say, hasn't anyone heard of or seen the Cougar eliminator!?

bret it works the same way as the vortec, except it's a roots type SC. Basically some custom plumbing to get the air into the uim. I don't think it makes much of a difference whether or not the blower is on top of the motor, as long as the air gets there.

Hopefully some people will copy what's been done with the cougar, really cool stuff

i dont realy think the r&d cost would be that high. not any highet than developing a turbo kit, and that has been done. i believe it is just a matter of someone taking the plunge and deciding to do it. i believe that mounting it on top of the engine is the best route. the hood is the real problem here. i am not an expert by any means though. keep in mind that the eliminator cougar was put together to look almost stock from the outside and to use a basicly stock engine set up. also they are running alot higher boost levels than has been applied to our cars yet so the internals have been upgraded to handle it. but i still think that with mild amounts of boost this could be done for about the same price as the turbo kit.
