I had a '98 SuperCab with the 4.2L and I now have a '01 SuperCrew with a 5.4L and I have to tell you, the 'Screw makes WAY more power and gets the same mileage around town and 1-2 MPG better on the highway.

The 4.6L is even better on gas than the 5.4L, unless you are Neal...

 

Hey, this is not exactly fare, I have not sold a single kit to anyone on this board, the system is still a project, I am only seaking help with its use on f150. The starter of this forum has intentions on sale of his product, just like me I don't see a reason why I should be punished for doing exact same thing!!!!!

Besides, I was planning on offering help and experience with his project!!!!!

 

The person that started this thread makes no mention in any of their posts that they intend to sell it. When and if they do, our terms of service that you and he/she agreed to will be enforced. If you do not want "to be punished" follow the rules that you agreed to when registering to use our forums.

 

Please oh please, tell me who told you life was fare!

 

Ya know, I was sitting here reading the threads and got an idea. If someone would come up with an upper intake for our 4.2L motors that would mount the Eaton M-90 supercharger (the same one on the T-bird, and I think the Pontiac Bonneville) wouldn't there be quite a few people interested? I know I would invest in it. I have always liked the Roots look, and appreciated the fact that if the SC failed the engine could still run. I'm not sure if the same is true about the centrifugal SC. Does anyone out there have any tech data (specs, drawings, tech details, etc) about the Eaton M-90 and/or the 4.2L engine? I know that a complete setup would take more than the upper intake (wiring harness, control electronics, pulley, belt, etc) but an intake would be one heck of a start. Really, I'm tired of digging and digging for performance parts for this great engine and coming up with next to nothing nothing. Any takers?

You wouldn't have to do anything with the upper intake other than, get rid of it. To let you all know on my progress. I've got the supercharger, along with all the intake tubes, intercooler, and throttle body. Tubes and intercooler won't be used, but wanted it so I knew how everything went on the Supercoupe.The 3.8 Supercoupe top has been raised 1" for a taller top and I modified the 3.8 casting in the top to say 4.2. The lower intake manifold plate is being machined now, then I'll be working on the riser and mounting plate for the supercharger. All of the supercoupe tubes bolted on with flanges, but they all had a problem with leaking. I have modified all of the hookup points so I can use silicon couplers and stainless piping to the intercooler, so I shouldn't lose any boost. As far as what else I may need is: Chip, aftermarket header (I'll probably get a MAC for the 3.8), Tom Morana says he can come up with a belt for it. The tough part now will be relocating some of the AC lines (have to be custom made). I'm also going to a narrower aluminum radiator, but it will be thicker so I won't have cooling problems. The radiator will be shifted to the passanger side then I will have room for the oversized intercooler. It's slow going, but this is a project that will get done. Also one more note to your post the other supercharger is off of the Bonnaville SES (I think I mis-spelled that) but anyways that is similar, but the air intake on that comes in the rear and straight into the intake manifold on the motor. I think it has some sort of internal intercooler, where the supercoupe comes in through an intake tube from the side, through the back, out the top and through the external intercooler, and into the the top of the lower intake manifold. It is really a simple set-up after you look at it. The temps of the compressed air can get up to 425 Degrees so I'd like to know I have a sufficient intercooler to get the temps down. Keep posting I could use some ideas on this project so it will be successful. I'll keep you all posted, thanks for any input.

 

Howdy,

hey curry....I'm doing basically the same thing as you are doing. Planning on bout 300hp. No need to squeeze it too hard, I just want a little more power.

Hey chilo6.... You need to back off on the and a little bit bud!

A real easy way to get a blower is to remove the upper intake, get a GMC 3-71 blower ( bout $700 rebuilt), make ur own blower to lower intake adapter out of 1/4" al plate, and a custom drive using an off the shelf belt and pulleys. Not too hard for a gearhead w/ some skills. Run 'bout 6psi and smoke any stock truck except a Lighting!

Get with me on what you are doing and how. I'm going with the SuperCoupe Charger. I got the whole assembly: Throttle body, intake plenum, charger, charger top, upper intercooler tube, intercooler, lower intercooler tube, and manifold plenum. I gave $300, and Wulff Pumps says he'll rebuilt it for me and put a protective coating internally to help the charger last and operate smoother. I was looking at the GMC, but I didn't know if there was enough room for that because it comes straight out the back. But anyways e-mail me we may be of some use to each other on this conversion.
