Forget the LS1 I want this!!! 383hp 2.6L V8 Naturally Aspirated. Oh this motor is the hotness, gonna be a rev monster for sure though. Probably be Ass in a heavy car, but in a Radical you know it would be hot hot hot. If I'm reading th specs right this motor weighs 250 pounds less than an LS1, Fark that's Light! ...And a Gixxer motorcycle Block would make an LS1 "small block" look huge. Radical Sportscars RPA V8 engine
Steve Prentice Design Limited have designed this engine for Radical Sportscars & their in-house engine builder Powertec. The RPA engine uses cylinder heads from Suzuki GSXR1300 motorcycle, the rest of the engine & transmission has been purpose designed for this project. Steve Prentice & Radical have worked closely with Quaife to design the sequential 6 speed transmission. http://www.stevepdesign.demon.co.uk/...ight%20web.jpg The RPA engine will be launched in USA at Performance Racing Industry show, Indianapolis on 9 - 11 December 2004 and in UK at Autosport International, NEC Birmingham on 13 - 16 January 2005. http://www.stevepdesign.demon.co.uk/...nals%20web.jpg Check out these links to Radical, Quaife, Autosport , PRI 325 hp Run http://www.pistonheads.com/gassing/t...?f=83&t=128671 Info on the Quaife Sequential manual 6 speed geerbox (quoted at 383hp run) http://www.quaife.co.uk/catalogue/download/84.pdf Info from Radical's website http://www.radicalmotorsport.com/new...a_v8/index.php RADICAL LAUNCH ‘RADICAL’ NEW SR8 - 2nd October 2004 https://www.radicalmotorsport.com/ne...images/sr8.jpg In 1997 the 1100cc Clubsport was launched, two years later the 1300cc Prosport, then the 1500cc SR3 and the SR3 Turbo, and finally this year the SR4. But just when you thought that Radical couldn’t get any more extreme; we go and do it. Enter the SR8, powered by the all-new RPA 2.6-litre V8 motor manufactured in-house by Radical’s engine company Powertec Engineering. Run on the dyno for the first time this week, the RPA – Radical Powertec Series A - put out an impressive 363bhp at 10,300rpm, with 196 ft lbs of torque at 7,000rpm. Powertec boss, Ted Hurrell, is very confident that his target of 350bhp at 10,000rpm will easily be surpassed. Hear the RPA V8 starting | Hear the RPA V8 running (audio files are MP3 format) The SR8, which weighs in at under 600kgms, is based on the hugely successful SR3 Turbo spaceframe chassis and suspension, but with an all new aerodynamic package. A new integral front undertray venturi, crashbox and side vents gives increased downforce at the front of the car, while a revised airbox layout at the rear gives improved air flow to the new high downforce bi-plane rear wing. A new six-speed sequential transaxle has been jointly developed by Powertec Engineering and Quaife. The transverse gearbox incorporates a reverse gear and the Quaife, torque based limited slip differential. Many of the car’s new features such as 280mm floating discs, 8½” wide front and 10½” wide rear BBS wheels fitted with specially developed Dunlop tyres, have been proven on the SR3 Turbo.

Each round will comprise two 50-minute races for two driver teams. Four rounds will be held overseas, provisionally at Spa, Nürburgring, Dijon and Anderstorp, with two in the UK at Silverstone GP and the Radical Cadwell Park festival.

That release should read GSX1300R. :judge: One Hayabusa engine for 2 wheels Two Hayabusa engines for 4 wheels. Makes sense to me! So if the current Turbo Busa dyno is mid 500's, I wonder what a twin turbo busa based V8 would do. :devil: |
