I like it. But we will have to figure out how to make more boost out of it, right now it only make 1psi. But there is hope I guess.

I'm going to guess that the above engine pictured is a 1.8.

I think the toughest thing for that system is manufacturing the modified intake manifold. I bet a design like that could fit under our hoods.

They said in the article it was a 2.5. It has an electric clutch that disengages when the manifold pressure exceeds 1 psi. So, I guess, someone could fab a smaller pulley to spin it faster to try and reach 5 psi, and just ditch the electric one. The whole point was to keep the motor making 165hp at high altitudes. I think the price is $2995 for the supercharger. I might check into this a little more. I won't turbo charge my car, but I would supercharge it if the price was right.



By the way, isn't this in the wrong forum.

Looks like a 2.5L SOHC to me. The supercharger is just to keep the manifold pressure up to 1 lb for high altitudes. It is an airplane application after all.

Pretty cool if you ask me. Makes me want to go fly my RS. The wing is too small though!

They already have a pretty good twin-screw setup that fits nicely in the engine bay. It sits beside the engine. There are people running plenty more than 1 lb of boost. I think the stage 1 kit costs 2499 and makes like 3 or 5 lbs. no IC.

Hey Igg...who is "they"?

And about that supercharger...where is the intake and the throttle body?

basically, you replace the intake piping and stock filter box, leaving the rest just the way it was. I'm not sure who makes it. Rimmer? or do they do the roots type blower? can't remember. its just a box and some pipes that blow straight into the stock throttle body, and its driven off a fab'd dual pulley on the power steering pump.

Do a search in AFI or on RS25.com. something'll come up. Its aerotech or something like that. I always get the name wrong .

I thought that this was intersting, thats why I posted it. If it is usable or not, I will leave that up to the NA guys.

I suppose it could be used on a honda with a fart can and a big rear wing. you could get thrust from the can and prop and fly on that stupid wing.

I want a subie motor in my plane after driving the one in my car.

Just trying to be helpfull here, not off topic.

Ah yes....the Rimmer.

[old school] I was actually on the board back when Rimmer was selling stuff here. Even back before they had the "Sidewinder" and it was a top mounted S/C that required hood modifications. Ugly! Several people here had problems with that company... [/old school]

I am curious about this new one though. Of course if you did want to install it you'd have to move the alternator...probably put it where the A/C compressor is (and axe A/C)...or possibly move the alternator out to where the battery is and relocate the battery...

But where is that one getting it's air from? Where is the throttle body?

Personally I think a centrifugal type blower (a la vortec) where the A/C is would be better...that way you could run the pipe along the side of the motor to a top mounted intercooler...but I am just talking out of my a$$.

Red arrow is intake piping, yellow is the throttle body(I think). I had to enlarge a very small pic, sorry it is blurry. The article says it is a 2.5 motor. Hell, just the article alone is excellent without the supercharger info. Thanks for sharing this with me, schmleff.

Here's a pic of one system:



Its run off the crank, it seems. This guy's on RS25.com. Running 8lbs IIRC. Nothing relocated. air comes from the fenderwell.

Admittedly, the top mount system pictured up there is sexier. if it had more boost I'd get it. It just looks damn cool.

I'd still prefer to run a centrifugal vs screw type...but that's me. I'm sure he has a quality setup...but I don't know if Rimmer even exists anymore.

And about that intake...I wonder where in the world it is going? (on the airplane supercharger).

No worries, stuff to think about while working on a glorious Friday.

IIRC MadMax has a custom kit based on a Eaton unit from a Benze.

These two kits should be ready by June 01, 2002. Note I said "should" not "would".

Screw type (Eaton or Autorotor) from Suby Sports

Centrifugal type (Rotrex or Holset???) from Templar (aka Kent) DNT Performance

Do tell do tell!!! I've been looking at forced induction and think a super is less invasive than a turbo, but I can't find anyone who sell one. Rimmer doesn't have any contact info again. Someone told me that they have gone under because of shady buisness practices. ...DARN!!!


So where'd you get your's?

If I could find a old Paxton SN92 Blower I could build a custom one.But paxton killed that line so I have to look for used and they are all screwed up.
