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

The 'Profile' concept car(based on CDW27) had a Rootes style Eaton blower and the initial set up had the same probs as Vortec re driveshaft etc.It was mounted above the trans and picked up on the the same intake manifold position as stoc...but did have a large intercooler...!!

Your right Rara the m112's are what I have, as well as the M90's and the M45's. The M90 would be my choice for the SVT as well. The install I am looking into does not mount on the intake or beside a head nor does it mount anywhere that it will need a jackshaft. There will be no jackshaft! You can also produce as much as 22 lbs. of boost with one properly set up. The hardest part of the install will be the ECU work, and since Ford has done it before and is doing it right now it can be done.

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.

Jusk to keep the facts in line also the owner of the intrgra in question wanted me to post the below comments

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.

don't even think about running an eaton without an intercooler... you might be able to get away with running the kenne bell twin screw blower for the escape (sans the intercooler) with low boost (twin screw run cooler then roots, giving more hp at the same boost level) the only data i saw to prove this was provided in a test "sponsered" by kenne bell, and was probably slightly "skewed". the kenne bell kits are fairly resonable, and the cost of the extra r&d would still keep it below what the turbo kit is going to run u. i think this would be cool for someone to try.

lol 151cube engine with a 112cube eaton... there is a guy with a "eaton takeoff" that is 160cubes.... lol the blower would have more displacement then the engine... hehe...

i think the m90 would even be a bit much for the duratech... maybe the m62 would be more appropriate...

i am offically a troll... so take my information and advice with a grain of salt.

I'll take your OWN word of advice on this one Bret. :p

What is the diff between an Eaton unit and the one by Kenne Bell?

i can't find that temp article... but here is something i found on the web...

"Screw type superchargers are derived from the Roots type concept but with vast improvements for street use. Although from the out side, screw type superchargers may look a lot like Roots type superchargers, on the inside you will find a twin-screw design that compresses air unlike Roots type superchargers which pump the air into the motor. Screw type superchargers have an axial-flow design that compresses the air as it moves between the screws to create positive pressure without creating the heat that Roots type superchargers can create. The Screw type supercharger's ability to produce a dramatic increase of power from idle and through out the rest of the power curve make them a great choice for heavy vehicles, towing or commercial use. "

not a whole lot in concept, the lobes on the kenne bell blowers are "twisted" more to make it more like a screw, hence the nick of "screw-type"

I have seen some empirical evidence that the units Kenne bell uses are a bit more efficient than a comparable size eaton, but I have yet to run across any indisputable test results. On the plus side for eaton, they have a rock solid reputation for durability.

no offense bret, but Muscle Mustangs and Fast Fords is hardly an ideal source for technical information, lol.

fwiw, the lobes on the modern eaton blowers are also "twisted" to be more screw-like, though not to the extent of the ones that kenne bell uses.
