Look like there is all sorts of neat new stuff on GT, including this forum. I've been so busy with our business that I've had to set a lot of my other interests to the side. Today I decided that my bike hasn't been running for waaayyy to long and got started on getting it back together. A stock 2000 Hayabusa in a good state of tune is capable of running about 194mph on top and somewhere around 144mph in a quarter in the high 9 second range. Its understandable and pretty well expected that one would want to try to improve on such a low level of performance. I put a turbocharger on mine and bumped the displacement to 1400ccs. The results were not earthshaking but it was enough to bump the power from 150hp to 300hp at the rear tire. I've gone 9.50 in the quarter at 158+mph on a worn out old street tire, spinning to half track and then starting to boogie on the second half. With a better tire the bike has gone 160, but that is at least 10mph short of where I want to be. Zero to 170 in three blocks is really about the minimum one should expect from a stock wheelbase street bike, don't you think? I split the cases at the end of last season because the tranny was starting to pop out of gear. I ordered a Motorhead undercut trans. While I was in there I decided to upgrade a few of the components that are prone to failure when the boost level goes up. The stock rods become marginal at about 320hp and the stock head bolts start to stretch at about 18 pounds of boost so those components were replaced. I also put in a better set of valve springs to offset the loss of seat pressure caused by boost pushing on the backside of the intake valves. With these mods I should be able to push the power to about 350hp before the injectors and turbo runs out of flow. Not a huge gain but it should improve reliability and at least there won't be too many people accusing me of riding what Arnold would call a "girly bike." An intercooler would be nice and could be worth 50hp but its not in my budget right now. After that the next step is an bigger turbo and bigger injectors. My old header is in sad shape too so I am welding up a new one. To accomplish this I first made a fixture from an old head to properly locate the collector so that the turbo will be mounted in the right location. Then its a matter of fitting and welding the pieces together. When the part is done I will send it to JetHot for their metallic/ceramic coating. Some pics: 1> The old and new cylinder bolts. See any difference? 2> 1397cc forged piston and a new tool steel knife edged rod. Should be good for at least 450hp. 3> The windmill and wastegate 4> My ratty old header 5> These are really helpful when building headers and other things 6> Parts used to build the new header 7> A slightly used Hayabusa head I borrowed. This is what happens when timing chains break. 8> A fixture I welded up to put the collector in the right place. Ugly but effective. 9> The collector properly located on the fixture 10> The first pipe is in place and the second one doesn't fit. Now the fun begins.
