This may come across as a rather stupid question, but it's one of my options. I have an Eaton M-90 off of a T-Bird SuperCoupe. Has N E 1 fabricated 1 into their 13B, or N E other blower? I'm thinkin' I can mount it somewhere like where the battery is and run the belts from there. It has a maximum of like 10 lbs. of boost, so it won't be a whole lot. Probably 7 or 8. Would I need to change N E thing? Injector sizes, fuel pressure regulator, fuel pump, etc.? Can U just "pipe it up" to the AFM and go from there or will there be a computer problem? I've seen a couple of other cars that had a roots type blower mounted somewhere besides on the intake and it worked really well 4 them. N E 1 else have suggestions or comments?

A lot more fuel than a na engine trim can supply. At least get bigger secondaries like 720cc, up grade the fpr with after market, bigger fuel pump like TII or better and get a SAFC to contrl the injectors. You'll run into trouble with pinging with the higher compression rotors so you have to be carefull. I only know of a few Nas supercharged.

If you are going to go supercharger on a NA do it the right way and get the atkins rotary carburated supercharger



i know a couple guys with it and its a bolt on application and works pretty good, with a weber carb i heard you can boost up 13 or 14

Atkins also sells the supercharger for fuel injected applications now. They are currently working on a setup that will use the stock injection system. I would imagine it will be a kit that comes with the afformentioned stuff: bigger injectors, fuel pump and some kind of computer upgrade. They have some info at www.camdensuperchargers.com

CrazyAssRX7 03-14-2003 01:32 PM

yeah i heard of that

it could be more affective but the carbed one will defently give you more power



so you will also not worry about injectors and all that other stuff

needa86NAat 03-14-2003 04:08 PM

I have looked for the atkins kit online but I cant seem to find anything on it? Is it something I need to call on?

rx7machine 03-14-2003 04:15 PM

Why not turbocharge? I'm guessing it's alot easier to convert..

Why not turbo AND supercharge?

1Revvin7 03-15-2003 10:06 AM

Here is my take on it:

The car is already setup to be turbocharged, it already has a t2 model, No point in wasting your time SC, unless you just want to be different. Why spend thousands to have supercharged 220rwhp? You could be there in a second with a t2 at alteast half the cost. The setup is also akward, a rotary engine with its high redline can easily overspin SC, and wear out their bearings, SC are made to run on low revving engines. Rotaries and turbos are made for each other, since they have such a high exhaust output they can spool larger turbos and spool them faster.

needa86NAat 03-15-2003 01:10 PM

Good point......and another thing... to compensate for high SC speed you can change pulleys... but the downside is it will take more RPM to get to sustained boost ie you cant change boost pressure with pulley change you only change how fast the max boost is achieved

needa86NAat 03-15-2003 01:14 PM

One thing I forgot.... this only pertains to roots type blowers not screw type...(ie Whipple Charger) which are far more efficient and do not heat the intake charge as much upon compression and can turn more RPM

I hate to say this, but that's not possible. I'll just leave U with this.....'think about it'.







And about the cost (between inatalling a turbo or SC), well this became my option because I already had a blower. I bought it to put on my truck, but I put a V-8 in it instead and the blower would have been too much for it. The only price that is a factor now is the accessories and some new parts. Just wonderin' if someone's done it.

I've seen it done on an 85 MR2 in an article in Car and Driver. With the way he had it set up he had 0 turbo lag. It was pretty sweet!

needa86NAat 03-16-2003 01:40 AM

i have seen it on a small block but It was a magazine car and the write up said the car never ran right..... twin intercooled as well.............but anything is possible

rx7machine 03-16-2003 12:17 PM

Just sell the supercharger and go TII.

Lancia's group B rally car from the mid-80s was super-turbo charged....all it takes is money! https://www.nopistons.com/forums/pub...1047683827.gif

could you take a supercharger like that, put a really big pulley on it, and run like 3-4 psi boost with only minor support mods? I want to do something like that to make up for the loss of power at my altitude.

Wouldn't be worth the cost, but to answer your question yea, you could probably get away with just a bigger fuel pump, a dyno/widebando2 could tell you what you need.

If I was in your position I would just get some nitrous.

how much has your swap cost you so far with a used engine,turbo

and drivetrain and not even a FMIC?

needa86NAat 03-17-2003 07:17 PM

I agree SC is not worth it...The turbo motor is the only logical choice to SC but why take off the turbo to SC... BTW in the fastest classes of sportsman drags... IE NOT NHRA... the turbos are kickin NOS & SC cars ass.... Ask Pat Musi... He when from BB Chevy on NOS to TT... and is faster and more reliable.... Turbos are " free horsepower"... IE no Sc to turn... It robs power
