E85 on 42.5# injectors?

for the love of god pulley size doesn't mean dick for the injector size. X.X pulley doesn't mean X size injectors are required. Its been covered a few times before and im about 99% sure people have run a 3.2 or 3.0 on 42s # injectors and rockers with headers on E85. That's a pretty simple common setup.

Boost is an arbitrary number and means little IMO.

Putting some 42s in is an ease way to switch to e85 now how far you can pulley down of course will depend on if the cars knocking or not, plus what other mods are done aka cam choice, rockers?, ported heads, exhaust mods?......

Also fuel pump, a rewire and fuel pressure make a huge difference for injector flow......

X injectors can are only good for X.X pulley size makes me cringe soooooo many variables left to address.
 


Ive already rewired my fuel pump with the casper's kit. Screw it, i have a wideband, lets see if i can use corn on 42.5's with my cam
 
screw draining the tank do it at the fuel rail into a bucket or whatever let the pump do it for you then once its a bit lower than 1/4 go put some corn in it.
 


Yeah, I just took it to little under 1/8th tank and topped it with e85. Just don't worry about really dialing in the tune until you get a couple tanks through. You won't be waiting long seeing how you'll be lucky to get 16 mpg in town. I'm averaging a little over 14 with a heavy foot.
