I have an A&A T-trim centri on a mostly stock C6 Z06. The blower made a bit more boost than I expected, so I kept the timing very modest at 10* with ~11.2:1 AFR. I'm used to the power now, and am curious if I can upgrade injectors, add FlexFuel sensor, retune and run E85 to try to get another ~40-50 rwhp.

A trusted friend and shop owner told me that the stock Z06 pump + BAP won't support ~700 rwhp on E85. I've tried searching but I haven't found conclusive evidence that he's either right or wrong. Has anyone here tried it?

I want to avoid meth if E85 is an option without upgrading the fuel system.

No chance. You need 30% more flow with e85

Why not just drop the BAP idea and run a second pump inline? Buy an ECS Stage 2 fuel system, injectors, and be done with it.

I've already done that sort of research. I'm just unaware if there is any headroom in the current pump + BAP.

Tech

It's an option, but it's another thing to leak or fail. Granted, the BAP could fail now. It's not off the table but I'm just curious if it's actually necessary.

So a shop owner and your researches have suggested it won't work but your wanting to hear what you want to hear? Last thing you with want to be cheap with is a fuel system. I wouldnt use a bap period. It's a band aid solution but it's your vehicle. What's the worst that could happen? Lol

Tech

You've jumped to a conclusion that isn't accurate. I'm asking if anyone has tried it. I don't plan to be the first one to try it, but if others have done it with good results, it's worth considering. I didn't argue with you or anyone else.

People on the internet loooove to regurgitate information they read somewhere else and pass it off as their own, so forgive me if I don't take your word as gospel without soliciting more opinions. Any random person can create an account on this forum and give advice. You didn't tell me if you had experience with a BAP and stock pump. If not, your opinion has much less value.

I do trust the shop owner but I also do my own research. Shame on me?

Or stage 1 so you don't have to drop the tanks

I've had experienced with bap n stock pump. Put it in the bin before I had to put my engine in the bin. Fitted a fore dual pump drop in that can grow with future mods. Bap's are a band aid solution to a fuel system that isn't up to the job required. I won't risk 15k of engine on a band aid fuel system

From my experience the stock pump won't withstand the corrosive properties of E85 anyway. You need a pump rated for E85.

Ethanol friendly pump and injectors

Was out of pump at 700rwhp on stock pump and bap on 91. Pressure was dropping good and making up for it in injector.

Yet...here you are, asking for opinions on the internet...





A BAP is a band aid and a shtty one at that. Get a pump and be done with it, or run the BAP till it fries your stocker and then buy a real pump anyway.

Always get more fuel than you need.. Fuel is like a condom, better to have and not need than need and not have.

I made 747rwhp on heads,cam,exhaust, ls7 with a d1 procharger. Hit 7lbs at 6800 rpm. I had id1300 stock fuel pump with a bap. Held fine until i ran it dry when i was lost and it over heated. Then i ran a intake walbaro 450, that was fine until it wasnt. Now i have a tripal pump from fore.

I spoke with Andy and Josh @ A&A and both of them said it's time for a fuel system upgrade or meth. Andy was slow to respond to my initial inquiry (like 3 weeks slow), or perhaps this thread wouldn't even exist. I pinged him again today and he replied.

In any event, I have enough feedback to make up my mind. I need a pump but I'm not sure if I'll choose one for meth or one for fuel.

Tech

That was on pump gas or corn? Sounds pretty strong for 93, but I don't think a BAP + stock pump would do 750 rwhp on E85.

Unreal

Guarantee he was out of pump, and just making up for it in DC with the large injectors. FP was probably dropping like a rock.

southspeed

If it was me I think I would do the ecs stage 1 and run a meth kit as well. And just stick to 93. Or do the e85 setup and the meth if it was readily available down here.

Money grow on trees in Mississippi?

Great question. I just talking my performance shop last week on this subject. My plans to upgrade the fuel pump to A&A Twin Pump and go E85 as well.
