Since a stock busa makes about 155 and the stock fuel system can safely support about 225, a 60 shot should be fine. Even with that shot you are going to need to add fuel with either a PCIII or an instant rich box.I have a mini pro funny car with a stock for now busa motor. I am useing a homemade air box and stock header only. How much H.P. can i get out of this motor running racing fuel with out hurting anything. I am takeing a guess of about 60.
They make a heavy duty output shaft. It will require splitting the case to swap it out. It is 30mm instead of the 25mm the stock one is. Sprockets are readily available, but the shaft it is not cheap. Breaking a shaft and destroying a good set of cases is not cheap either.Professor do you suggest a fix for the input shaft.
Above you say you have a stock busa motor, and then here you say your injectors are maxxed? Huh?Professer never used a dry system. Other than ease of installation not sure they are the way to go. If the motor goes lean you may need a dust pan to pick it up.My injectors (stock) are maxed out with my setup. If i go nitrous i will probably go to larger injectors or as i indicated a wet setup. Keep in mind this is a drag only car, no street.
