47# injectors with e85 - bolt ons/spray

[MGT2009]

Alright, I did a search and couldn't find really anything so I figured I'd make a post.


I'm looking to run e85 here soon on bolt ons and eventually bolt ons + 125 shot and have a chance to buy 47# injectors for a really good price.

My question is, is this too much injector for the set up or should I go ahead and get them?

I know NA wise, they're not going to help much but I'm more concerned with when I put the 125 shot on.

I assume you are talking a 125 dry shot?

125 plate kit

If it is a wet kit, then it doesn't matter your fuel injectors as long as you have a fuel pump. A wet kit supplies nitrous and supplemental fuel. If you are running a dry kit, then you need big enough injectors to provide the extra fuel the nitrous needs to maintain proper A/F.

As far as 47lb injectors, they will be plenty for a bolt on 3v switching to E85. What does your fuel system consist of and what specific nitrous kit are you looking at?

I haven't purchased anything yet, but i'd be looking at the gt500 fuel system, those 47# injectors and a nitrous outlet plate kit.

Their off the shelf plate kits for 3v's are wet kits, like this one.

What's your mod list consist of? Are you basic bolt on, or do you have heads cams or other mods at this point? I just want to be sure the GT500 system will be enough on E85. It SHOULD be, but I wouldn't want to steer you the wrong way.

JLT series III, CMCV delete, pypes LT's, off road x, stainless works a/b

down the road i'd like to add the frpp manifold and some 127500's aswell.

Too much? I've run 47lb injectors na before, they work fine. Plus you have to figure that the gt500 isn't always running wot, for normal driving it's not using much more fuel than what you have.

I've also ran 47s with E85 and boost. They started to fade at around 525rwhp.

Thanks for the advice guys.

I went ahead and picked them up. Scored 47lb/hr for $80. Not to shabby if you ask me.
