So I think I want to go E85 on my current setup. I'm running a Buschur FS635 with supporting modds on 93 pump. I want to do E85 and was wondering how big of injectors I would need (current FIC 1050cc) and currently on just 1 Walbro 255. I was thinking of ordering the Walbro 450 LPH (http://www.streettunedmotorsports.co..._f90000267.htm).

what injectors do you guys think I should go with to be safe?

 

If you are going to be using pump gas occasionally, I am a big fan of the FIC Bluemax 1250 and 1450 at that power level specifically because they are manageable on pump gas.

The wally 450 is a nice pump. I recenlty opted to pull mine out and build a double pumper tho. Base pressure was easier to maintain with the double, even with a fuelab fpr.

 

Only time I would be using pump gas would be just to clean out the injectors from the E85.

 

anyone else? any other input or anything?

 

You can always scale down a big injector if needed but you can not make a small injector bigger. Get the big 1650 high z's and be done with it.

 

I'm running the FIC1050's with a Walbro 400 on E85 and 91 and they work great. No need to spend any more money to upgrade unless you are built and want more than 475WHP/450WTQ

 

All im saying is if your going to purchase new ones for whatever reason buy the good big ones and be done with it. never buy another set.
