Question about M90 intake manifolds

[fivepointhustla]

I would be totally interrested. The price would be my only deteriming factor. I thought that the 3800 gm M90 was more efficient than the M90 from the ford?

[geldartb]

id be all over this. already got an m90 from a tbird sitting in my garage. definately interested.

Azreal, I definitely wouldn't use an M62 for this. I have one... it's pretty much maxed out. It's only good on an engine this size for about 9psi of boost before it starts getting out of it's efficiency zone. With an M90 it's a larger blower so technically it will take more power to turn, but it will also create more boost at lower rpm which=higher efficiency and less heat. Plus it's nice to have the option of running higher boost before maxing out the blower.

This would definitely be a more interesting setup than most peoples idea of just putting them on top of the UIM. It might just clear the stock hood, and certainly the aftermarket hoods many people already have. Might change if u add an intercooler, but hey that would be an option right?

The only two things that concern me would be the PS pump and the belt drive. I wouldn't want to eliminate the PS on a street car and there's really no place else to put it unless you eliminate the A/C maybe? On a drag car it wouldn't matter. For the belt drive I wouldn't run it off the same serpentine belt as the other accessories or it's gonna have problems slipping. It needs a seperate pulley and tensioner like the GTP's have. Depending on which other pulley it gets driven off of, that could cause frame clearance issues in some cars. It'll be interesting to see how you approach that. As always, you come up with the coolest stuff.

If the price is less than $1,500 I would get one.

kflo - As Brad was saying, it isn't extremely tall. I am planning to build a billet prototype in Jan/Feb and will have a better idea of how to proceed when that is finished.

Brad - Thats good to hear about the Beretta hood clearance. As you can see in the pic, only a small section is at the highest point and the rest is about 3/8 less.

I appreciate your offer and keep it in mind. Sounds like a good idea with the embedded viewer. A week long convention in Vegas also sounds good to me. Must be nice.

Phil - If all goes as planned, they will be cast. In the beginning, I will build some from billet and compare the extra machining cost to the cost of tooling to make the castings.

The SC does ave a bypass but it is part of a larger casting. I am planning to employ a bypass but just not sure where it will be yet.

I think the L67 SC is too wide for sure. Space is really tight with the 60 degree layout and the location of the injectors. If you could take a couple of pics and some rough outer measurements of the M62, I would love to see them. Although I belive the M90 would be better for a non intercooled application, some people may want to use the M62.

I am assuming that you plan to have these manifolds cast correct?

Also I am not sure if the super coupe used a bypass valve, but I would highly recommend using one for this setup. http://www.magnusonproducts.com/bypass.htm

Also, a few other cheap eaton superchargers are as follows

M90 from the GM 3800 engines (down side is that the way it mounts might be too wide for the 60*v6 heads.

M62 from a nissan frontier/xtera very cheap and easy to find. If you are interested I can take measurements as I have on in the garage.

Or the M112 from a Ford mustang or lightening pickup would be awesome, they are currently running around $350 - $500

If how it sits right now is only 1.5" above the height of a standard 3100 plenum, then it would only pop through the hood (of a Beretta) 0.5". When I had my 1" spacers on my 3100, the plenum hit the hood (and pushed it up slightly due to the sound-proofing ont he hood), so any cowl used to "hide" the SC would be minimal.

Oh, and Marc, if you need any help on the CAD side of things, let me know. I am actually looking into a way to be able to embed a DWF veiwer into a site page for all the current CAD files I have on the side, and hope to start making more files soon. I am just now wrapping up a week in Las Vegas for an Autodesk (aka AutoCAD for those that don't know) convention, so I've learned a few things that I want to try to put to use.

This would really encourage me to build a hybrid. I could deal with having a 2" cowl hood to clear a supercharger. I can't deal with it killing my view of the road though. What kind of timeline would be on this do you think? This would also eliminate the need to getting 3500 upper manifolds, I'd only have to source the heads then.

I think this is pretty kick ass. I'd love to see it go through.

[CNCguy]

I can understand wanting to use an M90 since they're used everywhere but if clearance is an issue why not use a slightly smaller supercharger? An M62 is supposedly sufficient up to 4L engines and will save 0.4" vertically in this setup.

The T-bird SC M90s are cheap, plentiful and are more effecient than the M62s. But, with the manifold design that I am planning will have a seperate top plate. This would allow addition of an intercooler, moving location of blower for pulley setup (FWD/RWD), possibly a M62 to fit, etc.

[CNCguy]

Yeah, swap the 3500 top end on it:P Thats the best route to go anyway.

The cost of development and tooling are high so I figured that if it only fits one style, it should be the 3500 heads. They are the best flowing and will fit older engines.

[montess408]

cool set up man any way to get it done on a 3.1L mpfi gen2 ??

[ihatemygrandamg]

Maybe in the future I would be interested. My grand am is my daily now but with 132k miles, in another year or so when I turn 18 I plan to take it off the road and make it a race car(lol thats not something you see everday). But yea Id be interested if its for the 3500 heads cause Im gonna be doing the 3500 swap when I get a new motor.

So what all would be included in the kit?

[Young Whitey]

I agree, this kit would sell.
