My turbo bike hits 215mph

[turbopete]

I've been building and working on my turbo system for a good few months this (and last) year. The Suzuki Hayabusa is probalbly (definately) the most commonly used bike today for forced induction (turbo and supercharger). In stock trim the engine can easily handle 300RWHP. Last year I decided to build my own system, with help and advice from many knowledgeable folk. The internet truly is a wonderful medium for sharing knowledge.

Since I was basically using stock engine internals, my target maximum HP was 300HP. I bought a new Garrett GT28-R, which is a ball-bearing design, and spools much quicker than a conventional bearing turbo. I designed and built everything (turbo headers, pipework, plenum, exhaust) myself, apart from specialised stuff like water-jet cutting and Tig welding. It's all built from stainless and aluminium. Encountered many pitfalls along the way but last weekend the bike did me proud. At our club's event (www.ultimatestreetbike.org) I was definately the underdog, up against bikes that were worth up to £25,000 (that's about $40k), but my little home-built bike did well:

Dyno: 300HP
Runway flyer: 215.7mph
Drag-race 1/4-mile: 9.4@ 158mph

I'm just doing a small web-page of the main parts of the turbo system build, if anyone is interested I'll post it in here.

YES PLEASE!

i would love to see that info.. how much parts were, plans, pics, etc.... I have toyed with the idea of a turbo on an old XL 350. Just for kicks and giggles. post your website here when you get it up!

215 mph!!!! wow. Congrats on all of your hard work paying off. The coolest thing is that you did it your self!!


I saw that turbo'd 11 on ebay too and it was mighty tempting to hit the bid button. But I have to finish my 750 SE first. I'll bet that thing gets pretty evil if its tuned right.

It was me yes. I did change the head gasket, but it wasn't blown so it turned out. What happened was this:

The tip of one of my radiator fan blades melted due to the heat of the headers, and fouled on the fan shroud. I warmed the bike up before putting it on the dyno, but with the fan stalled it blew the fuse, so the fan never turned on at all. The bike went up on the dyno, and set up for the run but the dyno operator got called away for half a minute. I left the bike running on the dyno because the fan wasn't on yet, but shut it down after half a minute or so. By then it was so hot, that when it went for the dyno pull oil was getting past the turbo oil seal and into the exhaust. At the top-end of the dyno run it blew out a cloud of smoke and it was shut down, but also boiled over, pouring water and stem over the dyno guy's foot. I assumed the gasket had let go and whipped the bike back home to change the head gasket. When I pulled the gasket there was nothing wrong with it.

Better safe than sorry though eh

The turbo bike must have had a heck of a lot of different stuff on it, like fuel pump etc. Did it have blow-through carbs or fuel injection like the GPz750turbo?
