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

Well, I have not really been thinking forced induction but after checking out the 03 Cobra 390 HP S/C 4.6L, well I am impressed. Looks like alot of cars are going with a Roots style blower including the awesome AMG 3.2 V6. Looks so straightforward. Wouldn't you be able to delete the upper intake manifold and put that S/C with a custom mounting bracket right on the lower IM?? No jackshaft just a belt to the drive pulleys? The S/C doesnt look more than 3-4" taller than the upper IM so a modest "hood buldge would be required. No huge packaging problems beyond a custom hood (maybe a nice carbon fiber-vented deal as part of the package). Keep the boost modest (maybe 6 psi) & no intercooler and just maybe put you up to the 250-260 HP range with nice torque & keep bottom end stock with good detonation management. Nice & simple. Did you guys really look at a kit for this route as compared with the too powerful (for stock internals) & complex turbo & vortex. I do not really know much about S/C so just throwing this out...

Exxcept someone would have to develop an adapter to secure the s/c to the LIM and properly route the air. Huge R&D budget! An alternate approach would be to try and adapt the escape supercharger to the contour somehow.

Dan, I have a couple of those superchargers that are on the new Cobra, they are made by Eaton. They measure 6-3/4 inch's from top to bottom, you would need more than just a small bulge in the hood. The lower intake would not work because it has individual runners going to the heads. With that supercharger mounted on top of the engine like you envision you need it to blow into a large open plenum first, and the Duratech manifold has no open plenum. You would need to fabricate a plenum bolt it to the lower intake then mount the blower on top of the plenum, that would add even more height to the install. I agree with you it would be nice to have one on a Duratech and I am researching that possability right now. However it will not be mounted on top of the engine.

No big R&D budget required! The Eaton superchargers are very versatile, they can be mounted a number of different ways. The hardest part of the project would be the ECU work.

the new Cobra uses an M112 (same basic blower as the lightning, which is what RedSVT has, as there is no way he has the Cobra specific one), and this would be far too large for a Duratech anyway, an M90 would be far more appropriate, one from an older T-bird supercoupe could prolly be adapted. It has been done before, even by ford, though only on Concept vehicles, IIRC the older Profile concept had an eaton blower on it (ask Terry, he would know about this car) snd the more recent cougar eliminator (trick setup on this car) had one as well.

Rara,
More feasibly would be an Eaton m62 out of the 1st gen SC'ed GM cars. The best place to mount this would be in front of(or slightly above) the front head...i think you will run into a clearance issue here though..then all you would need to do is route the output of the sc into the TB on the stock intake manifold...Also , you would probably need use a jack shaft with 2 pulleys, because I am not sure on the rotation of the m62, and more than likely you would have to mount it backwards... hmmm ok so maybe not feasibly...

Last year my buddy SC/ed his integra with a Eaton SC and just for kicks I tried to find a mount point for the unit all over engine bay. (eaton m90?? in hand) It almost felt like tetris geting the damn thing to fit in my contour.. Needless to say there is no room in any place that I could think of it working. (or find) The only way to do it is with a shaft like the vort kit or Turbo. There is just no room for the belt that the eaton roots needs. From what it sounld's like the turbo may be the way to go.

FYI: By the time he was done it cost about 4,000 to do it correctly injectors, smaller pullys, ex..ex.. + tons of tuning time and only putting down 180 t/ 220/h to front wheels and that is with a correctly built jackson kit @ 12+ psi. But then, on a light integra it's a monster.

I think that was with the upsized Jackson kit for the type-R with a m90??? In any event Eaton recomented the size of blower he had for motors up to 3.0L ish.. so it's the same one we would use on our cars.

Sorry if my memory is not 100% clear on the numbers.

I have thought about something like that for a long time. The only thing that would need to happen is this:

-Relocate the power steering pump
-CNC'ed adapter plate for Eaton SC that makes way for the injectors
-CNC'ed steel motor mount adapter that saddles the shaft.

Other than that, the intake and TB should be in the same location. Maybe that S/C to LIM plate/spacer has a built in water/air intercooler a la Lightning?

Tony,
I'm going from memory here, so don't take it as gospel (though my memory usually serves pretty well on stuff like this) but while an M62 may be made to work on the Duratech, I think it would quickly run out of breath, especially at higher rpm, given the free-breathing nature of the little 4V V6. I think to properly do it up, the M62 would need to be spun a little too fast for efficiency's sake (and durability) leading me to believe that the M90 would be a far better choice initially, as it could much more easily be spun in its peak efficiency range and make very good power. Not to mention that I believe the M90 is far more common, and less expensive to come by.
