Radical Sports Cars in England built a custom crank case and crank, and bolted the cylinder bores and heads from a, get this, Hayabusa to it.

They bolted it all together with little issue. The right head is on backwards, with reground stock cams to keep the intake side on the inside, and the exhaust ports on the outside. They built it as a flat-plane V8 (think Ferrari 360 Modena and Lotus Esprit TT).

It was in the most recent Sport Compact Cars Technobabble section of the magazine.

I did some searching, and holy cow, this thing is ridiculous.

On stock grind cams, the 2.6L Hayabusa V8 (named the RPA V8) put out 383hp at 10,000 RPM, with 8-throttlebodies. With the twin throttle body setup that will go in a race car, the engine made 372hp at 9,800 RPM and 207lb-ft at 6,800 RPM. Doesn't seem like a lot of torque, but it makes more than 150lb-ft from 4000 RPM until redline.

Not to mention it sounds... impressive. Scary at best.

That is the engine dyno. Impressive. I can only imagine what it would be like with some different cams, and maybe some FI.

Pretty cool, eh?

Shit shit shit!

I need to get home from work so I can hear those!!!

It's amazing. I've never heard something rev so fast. It's neat That's an amazing power band for an engine like that too.

sounds like a bike. :p

But it's a V8!!!!!!

I read about that.. Thats just crazy, like a mini F1 engine!

Remind me of my old rocket. God, I loved her when she screamed.

I read about that a little while ago. They make the perfect cars to go with it.

Yea they do! I would kill to get one of those in something like an Elise though. That'd be a hell of a ride.

Haha, it does sound like a bike or F1 car. Pretty neat.
