There are turbo Hayabusa’s out there but none of them on the level of this beast built by Hass-Serafini Racing. As far as I can find, it is the first to use a compound turbo system. Now I’ll be honest, I wasn’t completely certain what compound turbo system meant but when I saw it produces 564 horsepower to the rear wheel, I had to know what was going on here.
The basic idea is that a compound system is two turbos that are usually different sizes working together to produce boost. One turbo will feed the other before sending boost to the motor. This dramatically reduces things like turbo lag. Where with most twin turbo setups each turbo works independently from each other producing boost. If you are familiar with the terms “parallel and series” from electrical work, the twin turbo system would be ran in parallel where the compound would be series. Now that the lesson is over, back to this incredibly feat of engineering.
The plan is to be the first motorcycle to break the 300mph barrier in the standing mile. This seems absolutely bonkers really, having gone close to only 150mph on a superbike before and being blown away as to how much “tunnel vision” you experience. I can’t even imagine going double that. But I guess that is why I’m writing about it and not riding it. The first thing you notice is the huge turbo set up right where you would expect a headlight to be, which is so badass really. How cool must it sound when that thing gets spooled up at what appears to be less than a foot away.
When you first see the bike it doesnt really seem like much, but when he puts this thing on the dyno and opens it up everything changed, now my interest had peaked. 564 horsepower on a bike that weighs 650lbs. How in the world could you ever get that power to the ground. Drag bikes are able to do it so I’m sure it’s gotta be theoretically possible. The guys took the bike out for a couple test passes and reached speeds over 220mph which is very impressive in the standing mile. The only vehicles hitting those speeds are usually the twin turbo Lamborghini and GTR’s pushing over 2000hp.
Hass-Serafini Racing is still in the testing phase with the bike and there is not a set date where they will attempt the 300mph run. One thing is for sure, the bike most definitely seems like it is capable of reaching the 300mph mark. Its just a matter of getting enough traction to let Hass really open it up, what a ride that’s gonna be.
