Default Switching injectors, should I just go E85?

Well long story short, swapping to a FAST 102mm/NW 102mm combo to replace my LS6 and 78mm TB. Also had the converter restalled to 4000 from Yank, and swapped my old TR224 224/224 .563/.563 for a custom grind 231/234 .617/.612 from EPS.

Due to my old setup being an LS6 intake, I was able to use 30lb SVO redtops and put down 378/361 on a Dynojet in 90°+ heat. Not sure what duty cycle the injectors were running at but according to multiple sources I've seen those injectors are good for quite some power.

I ended up picking up a set of 42lb SVO's but then switched to a fast, so sold those and picked up some Bosch 36lb skinny injectors.

Now everyone's got me thinking about switching over to E85 considering the car has to get retuned, injectors need to be swapped, and I already have an Aeromotive 340 intank pump along with a fuel pump hotwire kit and the whole system plumbed with -6AN line with a C5 regulator in the line.

My question is, is it really worth the hassle of switching over to E85. Mods in my sig just add the new cam and 102mm intake and tb.

I looked it up on a couple different calculators and for 450 flywheel hp, 36's should be enough. However with E85 it says I will need at least 53lb injectors.

Anyone have any input for this?

Thanks everyone

that sounds about right, as going from gasoline to alcohol you basically need double the injector

To give you an idea, I am running 60lb injectors on my stock LS1 with boltons on E85.

Youre gonna need a bigger injector than a 36 for sure.

I have seen multiple cases where E85 eats away at fuel lines. Make sure your lines can handle ethanol.

I think I'm going to stick with 93 for now and see what the car does on the dyno/track. I contacted my tuner and he's fluent in tuning with E85 so it's always an option later down the road.

Thanks for the replies everyone

I wouldnt run e85 unless you're running on high enough compression or Forced induction. Just my opinion. But you can make it work forsure.

My deal was just the fact that it's not always available in any gas station I may go to. I drive the car all over the place to cruise nights and I'd hate to have to lug around a gas tank in the trunk.

But I've seen people who are gaining quite a bit on E85 with just minor mods and heads or cam cars
