Lonnie's double pumper E85 max limit?
 

I currently have his twin pump set up with 90lb injectors on my 347 h/c/I/d1sc setup making 802/725 on 14lbs and it's supplying fuel like a champ. My question is, I want to build a new setup with a Lsx 370 or 390 with a f1a and crack over a 1000 rear wheel on e85. Will this fuel system work or do I need to do something different? I'm gonna get id1000s but I'm not sure if or what I'll need to meet my goal. Any help would be appreciated.

Maybe you should post this in the fueling section.

Are you running E85 now? I'm thinking you could add a 3rd pump to achieve those goals. There is a member on here that is running a AES 385 and s88 turbo on E85 and needed to add the 3rd pump almost right away at low boost levels......probably under 800 rwhp. You will also probably want bigger injectors too. No less than 120 lbs for what you want.

Here is a link to the car I'm talking about.

Yeah your going to need bigger injectors for that power level. I talked to Lonnie and he said his reg. double pumper kit is good to about 800rwhp, but he can upgrade those to dual aeromotives i believe, that he says would support 1k rwhp on E85.

I have the same pumps from Lonnies and 95lb injectors. If you want the head room I'd recommend looking at 1600's or even 2000's. As for the pumps I'm in the same boat as well. I need to contact Lonnie on it, but maybe a third pump or bigger set of duals is in my future. Not sure as other priorities are taking over right now so the car is running in it's current configuration.

Edit: btw, my dual pumps are keeping up with 15psi, but I've run out of injector. My gut tells me that if I put bigger injectors in I'll find myself out of pump.

My tuner said he tuned a turbo car that made a hair over 800rwhp. He ran out of injector with the 95s on the dual pump setup, then he swapped to 120s and was fine. I'm also in the same boat as you too will.
