Time to mod finally...going E85 and need advice!

Hey all,

I know this has probably been discussed hundreds of times...tried the search function and didn't find a good summary of info on it.

So I want to convert to E85 with full supporting mods but maintain a safe reserved tune. Don't want to be blowing anything up.

I don't really have a HP goal in mind...just convert to E85 and see where I end up.

So with that said here are some questions.

I'll probably go to Tim Barth for tuning, seems he's the most reliable person out there for remote and safe tunes and the most popular for a reason. Or am I wrong on that?

Parts list:
What pulley will I need? Suggestions?
Bigger injectors of course. What will I need?
Boost a pump or dual fuel pump setup?
Cracked PCM of course for tuning. Best source for that? I'll also need a hand held or mounted tuning device obviously, best one out there?

I think that covers it for parts? Pulley/PCM/Tune/tuning device/Injectors/Fuel Pump

Am I missing anything?

And finally I'd LOVE to have a flex fuel tune. I read a while back tuners where working on that but not sure if one's available or functional yet or not? In the event I can't find E85 anywhere it'd be nice to run it super low and fill up on premium and have the PCM do the rest of the work. Ran into this issue on my last car...Dad was driving it and couldn't find E85 so filled up on premium gas...shortly after the rod went through the engine block and out of the oil pan....ugh. lol Of course the hand held Diablo tuner was in the trunk and could have flashed the premium gas tune to it beforehand but he didn't know. lol

i went in to this upgrade dumb and came out well educated.
for what it’s worth
no matter what fuels you run there are some facts that you need to be aware of.
1 The old saying that there’s no substitute for cubic inches is only true to a certain point.
for instance the factoru crank is the strongest crank you can get. No questions no doubt. That was one I really had issues with. But Dusteroff down to the lead engine builder for HHP is in total agreement.
2 The stock pistons and rods are the weak link in these engines. Again most knowledgeable people concur.
I just bought the best bullet proof pistons and rods I could buy.
the 426 was on my mind but I’m giving up a bad ass crank to get the stroker.
a 362 built and tuned by the right guys is fricking AWESOME!!!
it’s absolutely reliable at a hp threshold that will send you screaming help me to mama.
Remember when you put a 10 over on the bottom and a 275 on the top you are approaching what the old blower on a Redeye will take. Camshaft on the Redeye was not deemed needed.
I agree after listening to the builders thoughts on that.
heads need to be solid. The proper injectors recommendation from your builder is a must. Get him what he is comfortable with.
This is where opinions matter. CAI‘S do matter when you are screaming a huffer. Again listen to your builder.
buy the best you can afford. God knows I could have saved money, even though I was givin that option a few times, I don’t want to se the inside of the mother until time to freshen it up.
get ready to buy 17” or better yet the 15” conversion so you can run the sticky street slicks. I tried the super wide street tires and they will just get you into trouble. Rear carrier lock outs, upper and lower rear control arms, aftermarket driveshaft, inter chiller spacer plate and blanket for those hot days on the street.
After you get thru this find a true E85fuel source and test every drop that you put thru your new baby. I buy nothing but E85R race fuel even though I’m allowed to be as low as E70 with a little care.
I know I’m rambling but when you start down this hp rabbit hole you open a need quiet often to keep it competitive
Good luck and enjoy!!!!!!!!
