snowmobiles.

there are PLENTY of 440's out there with fuel injection - Artic cat uses Suzuki technology. Skidoo uses bombardier which is also good.

A few comments. You MUST inject the oil into the crankcase to lubricate the crank and rods.

You want to inject the gas into the transfer ports, and you want to inject starting at BDC, then delay from there.
For WOT, they often run a second injector into the crankcase just to get enough fuel at WOT.

Also, the 440's I am talking about run 8500 to 9000 rpm, and make easily over 100 horsepower. for your order car, you can probably use the low RPM circuit only.
