Croc Posted November 30, 2011 Share Posted November 30, 2011 After educating a member by phone last night on the wonders of the internet and in particular, Blatchat....I offerred to post his technical question here as for me to go through the process of explaining how to register here would be slower. I can then print out the answers and show him.... I have already demonstrated the search function for all history, just trying to add to the existing Blatchat knowledge already posted. Anyway, here is his question: I am looking to turbocharge the Hayabusa engine in my car and would like to hear from anyone who has lived with a turbocharged seven. I have lowered the compression, installed heavy duty head bolts and adjustable cam sprockets. Other than that it is basicaly stock. I have a Garrett GT28 turbo and a big intercooler. I am hoping to run 7 or 8 psi and would be happy if I could get 250 RELIABLE horsepower. I am comfortable my formula will work well in a bike but a car application is different. The loads on the engine are greater and more constant than in a bike and I have concerns with heat buildup. Can someone with experience with boosted cars tell me where the "bodies are burried". I have a bike engined car already but I have never seen a turbo bike engined car so it is difficult for me think my way through this. I would prefer not to reinvent the wheel and would like to learn from the experience of others, rather than beat my own path and leave a trail of blown engines in my wake. I read a number of roadtests in the car magazines of a turbocharged D*x and they rave about it, but I am sure there is a downside. Surely by now enough of these fantastic engines have been boosted that the weak links are known and fixed. Thanks in advance Link to comment Share on other sites More sharing options...
myothercarsa2cv Posted November 30, 2011 Share Posted November 30, 2011 I thought Americans were all about the cubes? If I was stateside, I'd be sticking a Chevy midget motor in... here 😬 😬 😬 😬 Sorry I can't be of any help at all Link to comment Share on other sites More sharing options...
davedlr Posted November 30, 2011 Share Posted November 30, 2011 No experience - but it could be worth seeking input from Dax Rush owners, the turbo'd Hayabusa seemed a popular engine choice for them, more so than Caterhams. I would have thought the Dax Rush was similar enough to provide the same lessons learnt. Link to comment Share on other sites More sharing options...
peterg Posted November 30, 2011 Share Posted November 30, 2011 Croc, get yourself (or your 'friend') over to the WSCC Boardroom (www.wscc.co.uk - it's free to register, post a question etc) there are at least a couple of turbo Busa cars on there (from memory there's a guy with one in Greece as well) and they'll have answers to all his questions 😬 Edited by - peterg on 30 Nov 2011 15:51:53 Link to comment Share on other sites More sharing options...
robmar Posted November 30, 2011 Share Posted November 30, 2011 I only know of one caterham hayabusa turbo - that was Adam Hays, but I have not seen it or him for 3 years... rob Link to comment Share on other sites More sharing options...
Pendennis Posted November 30, 2011 Share Posted November 30, 2011 I know someone who has recently done it, he went all steel bottom (security), has had to deal with with water issues, up the primary exhausts, fuel pressure increase, think clutch was upgraded and then there is the old gearbox, that has to be addressed.

Ivaan Posted November 30, 2011 Share Posted November 30, 2011 I think Evotell ( Terry ) in Alberta, Canada has or knows of these. Edited by - Ivaan on 30 Nov 2011 20:07:20 Edited by - Ivaan on 30 Nov 2011 20:08:18 Link to comment Share on other sites More sharing options...
BBL Posted November 30, 2011 Share Posted November 30, 2011 John Hartley might know something about it, as he offers modified Hayabusa engines for sale specifically for installation in cars. I believe his pages start at www.h1v8.com, where you could locate his phone or e-mail contact info. Link to comment Share on other sites More sharing options...
The Pikey Posted November 30, 2011 Share Posted November 30, 2011 Holeshot racing in Ireland are the people to speak to. They did Adam Hays engine. Jason Link to comment Share on other sites More sharing options...
Area Representative skeetsy Posted December 1, 2011 Area Representative Share Posted December 1, 2011 A Turbo Hyabusa Seven, eh? Back at the end of October I went to the Kit car show at Exeter (and it was a bit disappointing to be honest) but while I was there I did clock a very impressive Turbo Hyabusa Seven project (sadly not a Caterham - but then nobody's perfect 😬) You can see some photos here and I'm sure if your friend gave the chap a call he'd talk him through some of the issues he's had along the way - He was telling me that he had custom made the exhaust manifold to prevent the turbo sticking out of the side of the body and he's hoping to reach 1000 bhp/ton Good luck to your friend with his project though. All the best Richard Link to comment Share on other sites More sharing options...
