How does Octane affect my bike's power and performance?
I have a 07 Hayabusa I’d like to wake up a bit, my last bike was a stock 05 GSX-R1000. I'd like to also think reliability as I've got a touring set up for it to take 5 and 6 hour trips. From suggestions I'm looking at the intake cam for exhaust, your Gen3 pipe, Power Commander. And local guy mentioned removing a gasket that would bump the compression a half or so. ? got me... he is reputable wrench/builder though. Does any of this sound as good reliable set up for my 07 Hayabusa?
What is the highest compression ratio you guys have run milling of head to achieve it and what power gains for the Busa? (JE Flat Tops). What are the tightest piston to valve numbers you would be game to run? I will certainly be rechecking my MAC numbers when I take the lid off, my initial measurements were taken perpendicular to the pin with a .037 and .036 so I guess that averages to .0365?
I am looking at your "Top End engine package" or the "piston kit with cams" for my Hayabusa. Assuming that these packages increase compression ratio, what octane fuel is needed to assure reliable operation? The best fuel I have around here is 90 octane at the pump.
I had a few questions about the '08 Busa pistons. I was wondering what compression ratio your pistons are. How high can the compression be for a stock exhaust? We plan on doing cams and modifying the exhaust cans internally. I also have the thin Cometic head gasket if needed.
Can you tell me what approx comp ratio my Busa Race motor would be running? Your 84mm JE pistons, 10 thou off head, 36 thou piston-head, stock base and head gaskets. (02 Busa)I am getting the head built with 1mm oversize valves and I also want to get as much comp into the motor as “safely” possible. What are the tightest piston-head and valve-piston numbers you have seen used reliably? I realize that you might feel the need to give me fairly conservative numbers to cover your arse but I accept that if I bang my motor it is MY FAULT entirely.
Can I use VP MR12 gas in my 1397 Busa?
