Woot!! V8 Hayabusa!

[Turbo5Speed]

For years people have unsuccessfully tried mating a 4 cylinder Hayabusa engine to things with 4 wheels.A company in England took another approach: They used 2 four banger 'Busas to make a V8. They fabricated a custom crankcase/etc for it and reset the firing order so it doesn't fire 3-7-2-4-1-etc, but fires in a more even order for the new design.The best part.. 383hp@10,000 RPM (Yes, ten grand rpm) and the ft lbls are 200-something (I want to say 270, but I don't remember the exact number) @6000 RPM.They're producing 2.0, 2.4, and 3.0 variants of the engine. Imagine THAT in a Vibe

Those Busa's are mean, people in Vettes try to race them...

Oh, I forgot to mention: The engine weighs only 204 pounds, and is 2 foot by 2 foot and is only 18 inches deep.The company producing this V8 'Busa is Radical Sports Carts in Peterborough, UK, and I believe they're calling it the Powertec RPA V8.With the firing order, a chevy V8, for example, fires 1-8-4-3-6-5-7-2, in the 1-3-5-7 bank the order is 1-wait-wait-3-wait-5-7-wait, and the 'busa engine couldn't be ran like that.The Powertec engine has a flat plane crank like a Ferarri or Lotus Esprit. A flat-plane V8 crank looks just like a 4 banger crank except each rod journal is wide enough for 2 rods. The same odd-numbered bank on the Powertec fires 1-wait-5-wait-7-wait-3-wait, so it's nice and even. Instead of sounding like a V8 rumble it sounds like 2 high-strung 4's firing in harmony with each other. (They had to do some more work since on the 'busa engine the intake manifold is on the back and the exhaust manifold is on the front, and the timing chain is on the right. To solve this they put the right head on backwards, with the timing chain on the back. This resulted in the turning the right side cam lobes in the wrong direction, but grinding new cams is nothing considering they already made custom crank/crankcases for it.Quife is making 2 gearboxes for it, a front engine rear-drive transmission, and a longitudinal transaxle for midengine cars.The numbers (I checked them again) are:383hp@10,000207ft lbls@6,800Offered in 2.0, 2.6, and 3.0, although the 2.6 is the only one up and running at this time.383 HP that revs up to 10500 RPM's? Turbo that, please You want one, don't you? Before you shoot yourself in the head to end the crushing weight of your jealousy, just remember, it rains a lot in England and the food sucks.

[Turbo5Speed]

I know, just give it some wings (Or hold your arms out) and you'll make it to China.

[ragingfish]

Call me ignorant too:What is the deal behind the randomness that is called the firing order on an engine? Why not just fire, for example in the Vibe, 1-2-3-4? Why is it whatever the random firing order it is set at?

[Stang2Vibe]

Firing orders are never random. Engines are designed to fire in a goofy order for a particular reason. I can't say for sure what the exact reasoning is, but there are probably several reasons why firing orders aren't sequential and they likely involve things like stress on the block and internal parts, heat dissipation, intake and exhaust flow, power output, and smoothness/quietness of the engine.

[Turbo5Speed]

I'd have to go with the heat disapation one. If an engine fires 1-23-45-67-8then it would be heating up the ones about to fire next, which would increase engine temps, which wouldn't be very good
