rotrex supercharger

Pin that against the current claim of 30 million Corollas ever produced. That's strict economics my friend! [ok, end Off Topic]

yea my thread has been hijacked. wtf, all i wanna know is if can be done, and if yes how much will it cost. if you wanna talk engines make your own damn thread. thank you

Hey there,

Sorry for continuing the OT.

To directly answer your questions, yes it can be done with some money and determination. In Chicago, there should be loads of shops that can do mandrel bending. Look in your yellow pages at exhaust shops. Usually there are only a few around (mandrel anding machines are expensive), but they should be there. If not, you can always buy universal bends and silicone couplers off of ebay. Just make sure you get good T-bolt clamps to hold back that newly found pressure you will be making!

As others have indicated, the S/C route is a good option if you want moderate, low end torque increases, but limits ultimate the ease of future power upgrades.

You could have a pulled milled from stock aluminum, but that will cost you big bucks. You might want to try out an xA or xB (??) pulley, I can't remember which was mentioned earlier to see if it will fit our needs.

Cheers and good luck with your project.

Carvin: Bending pipes is the least of you worries. Read my previous post, our engines pulley system is not enough to support the Rotrex pully requierments. Why are you speculating or guesing if the Rotrex will work?

Basically, our Yarii use a single pulley system while the xA/xB use a double pulley, hence it may be possible to use the extra pulley groove to run the supercharger. But the best bet would still be a custom-made one.

so i guess its just a pipe dream for now. i will just play the w8n game til companies make some serious products for our car. like i said just wanted to hit close to the 200 mark, with a better low end reponse. so the rotrex was the way i wanted to go.

The single pulley is not the problem, its the amount of grooves our pulleys have. A minimal of 5 is needed but 6 is what Rotrex suggest

200HP to the wheels or flywheel? Do you realize that the turbo kit that ZPI has available did 175hp to the wheels? That is over 200hp @ the flywheel. Plus 170LB of torque. As for low end response, turbos have advanced 10 folds in the last 5 years. Lag is almost a thing of the past. If you pick the proper turbo built specifically for the size of the engine.

well how about the heat dissapation?

I think you are trying to reinvent the wheel. Run a intercooled 5-7lb of boost kit & you get 175hp to the wheels. What more do you want? More power? Install a set of lower compression pistons & a set of rods. Now you will be over 200hp. In a 2300lb car that is 11.5hp per pound. That is better than a new Z06 Vette.

s/c cool, but its more stress on that tourqe struglin 1.5. Would rather boost off the exhaust rather than put more stress on the crank

Dear Underdog Racing,

+1 interest

[RShatchback]

+2 - I've got the money, I'm just waiting on someone to release a supercharger or maybe even two different companies, so i can make a comparison before buying it. But I'm waiting...

[sdmf]

so ur saying there's a chance couldnt someone just modify the rotrex pulley to 3 groove?

Anything's possible... If you don't believe it, go grab a DVD of that TV show Monster Garage...
