Ok, whats the real story behind the high flow injectors?

[GPR/STX-15F/RXT]

Glen Perry from PPG say that they are a little "overkill" for rec riding, your thoughts?

thanks

He never mentions a size, I think he is refering to the new Riva Stg III that uses 50 lb injectors. Sometimes you have to fill in the blanks on what people say and have to be aware that sometimes it's multiple choice!

Do you know what the real flow rate and at what duty cycle the stock injectors are rated at. Also do you know the firing sequence of the stock injection system like batch or sequential and how may squirts per 720 degrees of crank rotation Sea-doo uses. Do you know if the stock system is Speed-Density or is it Alpha-N like the Rotax Racing setup appears to be looking at the software. I will admit it is possible that the software could have MAP in the fueling equasions and as such have some sort of hybrid.

I'm just installing the 42 lb injectors today and saw the nozzle length is about 1/2" shorter than stock? Is that right? Stopped until I get an answer.

I dought that it will matter assuming the o-rings wind up in a location that everything works. The injectors should be able to rotate but not move in and out more than a very little amount.

the body of the injector is the same - where the orings are - but the nozzle protrunds a 1/2 " further on the stock one much like an extended spark plug tip... The nozzle position will be higher in the cylinder injector cavity. Doesn't seem right.

I've got 12 hours or so on the new impeller with 42's and no problems. Yes the injectors are a bit shorter. The fuel will have no place to go but into the intake even if the injectors are shorter.

are you guys seeing a big difference in fuel mileage??
