Hello,

I search in to the forum, and in don't find what i want...


I shall will to put a super charger in my 944 2.5 of 1983.

I find a Eaton M45 (mini cooper S), i just want 200hp... It's more for the fun than the competition


I would like knowing if it's good for my car, but i dont want to revise my volumetrique rapport..

And with the SC, i put a intercooled of 944 turbo, and a regulator 3psi...+ injector of 944 S2???
And a piggyback pour fuel system!

Sorry for bad level of english, because i'm just little french student


thanks

itd be better to use a larger displacement supercharger. several people have already and i am about to use an eaton M90 off a Ford Thunderbird.

larger displacement supercharger at the same boost level will be more efficient because it has to work less. you could try an M62 off lots of late-model Chevrolets, Pontiacs and Buicks.

you will also need to have either a log intake manifold made or make something like

I haved seen lil mule project

And.. this....



It's simpler.. No???

V2Rocket

that is with a centrifugal type rather than a roots type

Flo44

what's difference for configuration???

V2Rocket

centrifugal is like a turbocharger with a belt and gear system driving the turbine rather than exhaust gas. they take a little longer to develop maximum boost pressure and are good for making peak horsepower because of good efficiency.

roots types like the eatons have two rotors that spin in opposite directions that come very close to touching and the air is forced through the small space and makes pressure. these are very good for low-mid speed but at higher rotational speeds become very inefficient. they are good for making lots of low-down torque and midrange horsepower. they are also very inexpensive and easier to find than centrifugal types.

just wondering for reference what is the largest supercharger you can put on a NA car? I know a 6-71 isn't going to fit....or maybe...lol

V2Rocket

you dont want it going too big because the volume is too big for the engine to take in.

a 6-71 is designed for a 7-liter engine lol, not a 2.5

the eaton m90 is designed for engines of displacements of about 3-5L, itll work on a bigger one but wont be as efficient as putting an M112 on there.

uhm uhm..

It is there that my English makes defaut


I know the specifications for Eaton, thanks..

And i don't see when where you want to go whise

The stock admission pipe is not compatible with Eaton??

Thanks for your efforts of comprehention

What about a side-saddle belt setup like the Jackson Racing Miata package? I'm all for it -- as long as someone else does it first.

Flo44

lol!!!

I don't want to make a BIIIIIGGGG one! My 928 (look my 1st message) will stay stock

Flo44

Potomac-Greg, you don't use a intercooled????

Is not necessary?

When is it necessary? Always with surcharged system

krystar

at low psi, u can run non-intercooled. of course it's better intercooled but sometimes it's really hard to route.

my acura rsx (honda integra to rest of the world) has a m62 eaton and i'm doing 9psi not intercooled. i don't knock and it runs smooth so adding an intercooler is alot of cost without alot of gain right now.

Flo44

The little eaton deal 0.8BAR (the conversion... 8PSI??)

it's low psi, good!!

The intercooled of 944 turbo was "big" i'm obliged to cut my radiator grill.
I don't want to, because my car is in good conservation
