Pump and injector capacity
I am curious as to how much flow the stock fuel pump and injector can handle? I am thinking of switching over to alchohol for my new build and im pretty sure ill have to change injector but dont know if the pump can handle flowing twice as much fuel(alky burns roughly twice as much fuel than gas).
Anyone know? thanks guys

Well your op pressure is regulated @ 51 psi, look on the pump for flow rate. We run E-85 needs more flow w/blue next size up from stock BRP injector. You may need two sizes up run some test.

e-85 is pretty similar to alcohol after i break in on gas ill buy a few galllons of alcohol and see what it does. with different injectors what is needed to be done to the throttle body? and pc3/5 can still tune without a problem correct?

We have a BRP 50mm TB and PC5 tunned the E-85 right in works fine, watching rubber lines for deteriation and there is no bare magnesium and al to break down I know of. Getting read to inspect the lines and fuel pump in the next few days will let you know. We been running it about 25 hrs now, won several high level races., no probs easy on the wallet too.

we are trying to go the e-85 or e-98 route, we spoke to can am race development , they suggested we use an injector out of a renegade 800 " green injector" my cost under $100.00 new, { nobody seems to know flow rates but they all agree that it will work} ordered it today for the new bike build, cant wait to get it on the dyno to see what the e 98 does...HE HE HE
looking foreward to NOT buying $76.00 5 gallon race fuel

I was told that it will work on nine to one we are going to thirteen point six to one which is what most are going to to maintain dependability
