Nitrous Experiment How Much Can You Add

 

We wanted to carefully upsizing jets to see how far we could go without blowing the engine. We were careful. We added considerably fuel visavis the Power Commander and this worked well. We could tell from behind the bike videos of burning gas with it too rich at some points and some jets. However, once we got a handle on that we moved to the next jet giving what we figured to be 310rwhp and bang we throught we blew the bottom end of the engine. But fortunate for us, it was just the clutch

After a new HD clutch was put in the bike, the bike ran fine and continues to run fine, however we have backed of the hp to 280. We feel this is a happy optimum to keep the bike in good shape. Keep in mind this is 280rwhp. 

So with our new clutch we could return to the jetting to give us the 310rwhp but we are at the tipping edge for an older bike that has had nothing done to the engine and with mileage.

Naturally if we were going to spend a summer doing some serious racing, we would strip and rebuild the engine properly and maybe add a supercharger or turbo along with some nitrous...and hell we still may do it, not to go after track records, but rather to study our times vs what we have done to the engine itself.

One thing I and we have come to realize is that the suzuki hayabusa engines are extremely well built and really tough. We know this from the grandfather of the hayabusa, the GS1150, which was one of the most common drag bikes at any track and still continue to hang on.
