Check DP1's proposed engine-V8 Busa
The motor is based on two Hayabusa top ends joined together. 360hp, 210 lb-ft, about 220 lbs weight.
more details at

For those on here who dont't know the site, it has a lot of cool stuff, including a detailed build diary of a Busa Westfield in the
"past"section

Just for clarity, he's not developing the engine himself. He had some earlier posts about it on his site and if you find them it'll
probably identify the company doing the work - he's not involved financially AFAIK.
About the engine, I'm curious about the specs. I don't believe one can take two Hayabusas and expect to see double the power. With the
increased rotational mass I can't see how it could have the original redline, and because of that I'd expect the real power to be maybe
1.8X a stock 'busa.
Then there's development. 1000s of miles and many teardowns are needed to verify cooling and especially oiling is up to the task. Anyone with
a CNC machine can make a V8 from bike parts, making one live is completely different. A proper development program costs millions.
Speaking for myself, this engine will be so expensive it's useless other then something interesting. Kind of like being offered a date with
Angelina Jolie for $1 million... yeah, whatever.

what are you saying kb58 is that the engine will last about as long as any of us with angelina jolie

Not sure I agree with your theory... IMO if done correctly there could be less rotationa mass than 2 separate Busa engines due to shared crank....
also internal crank rotation energy would be shared to further increase its efficiency.
Of cause developing a crank and block thats as strong and effiecient as the original would be a huge challenge considering the busa is already almost
untouchable for Power per litre.

First time i've seen that site and I was very impressed. Great looking and engineered piece of kit, would love to develop something like that
for myself in the future.

From the Radicalmotorsports website:
quote:
"Radical's new lightweight motorcycle-derived Powertec V8 engine, which is due to be track-tested this summer prior to its launch at
Autosport International next January, is set to open important markets for the innovative Peterborough-based sports racing car constructor.
The ultra-compact engine, which shares some components with the Suzuki Hayabusa 'four' used in Radical's SR3 and Prosport models, is
expected to develop 350bhp in its 'standard' 2.6-litre form, for a target price of £14,000 + VAT .
Radical Sportscars co-founder Mick Hyde said "That will make it a sure-fire option for speed hillclimbers, and we have already had some
unexpected interest from leading grass-track racers who have recognised it potential."
By changing the crankshaft throw and pistons, which will increase the cost, 2.0 and 3.0 litres capacity versions of the engine will also be available,
to suit different applications and class structures.
Designed by Steve Prentice, the V8 carries its in-line oil and water pumps low down, and features a Formula 1-Style cellular dry-sump scavenge system
for maximum reliability. Prentice reckons it will sound "like a slightly out of tune Cosworth DFV".

Didn't the same firm from Peterborough do a V8 based on 2 R1 cylinder blocks a few years ago? They had one on a stand at Donington maybe in 2000
or 2001. The crankcase looked like it was machined from a solid aluminium casting with the pistons sharing crank journals on the opposite banks. It
didn't have any fuelling equipment fitted and it looked very compact.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
