you want the gss342, so 11142

 

Thanks ^^

 

OK, installing the aeromotive 340 fuel pump right now. im doing the normal trimming and shaving to make it fit. The directions say the factory wiring may not be sufficent to handle to current draw of the aeromotive. says i need to use the new wires that come with it. (which I have) and then goes on to say that i need a direct alternator supply point. wtf is that. kit came with a new filter. small rubber fuel hoses, and the wire pin connector. and does the polarity need to be changed or did they fix that issue? thanks

 

I used the aeromotive pump and ID1000cc injectors in my 370z with E85. I made it to 528rwhp DJ with no signs up the pump falling off yet. This was at 52psi static fuel pressure. I ended up running a little more boost later on after the dyno, probably another 20-30hp.. my only fuel pressure gauge is under the hood so I couldnt watch the pressure to see if it dropped... but my AFs were staying completely in check without having to dump fuel on the top. So the Aeromotive pump itself is definitely adequate for your power goals.

The 370z does have a little better of a fuel pump housing. I would say that there is a chance that an Aeromotive 340lph and especially a Walbro 400lph *may* have trouble hitting their full potential when being held by the 350z fuel pump housing. While power in the 600s is easy done with that housing on gasoline.... I am not so sure about 500 on E85.. you might be the first one to try as far as I know.

Last week I spoke to a customer using our Stage 0 RFS. He was unable to make more than 520rwhp on, IIRC, straight gasoline. He tried upgrading to a Walbro 400lph, and it did not solve his problem. You did mention that you have a CJM RFS, I did not see if you mentioned which one. If you are on a Stage 0 kit, I will have to say that I dont think you will be able to achieve 500rwhp with E85 due to restrictions in the stock plumbing, basing this off the results of the customer I just mentioned. But if you have, say, a Stage 2 kit... than the only chance of being stopped short of your goals is if the fuel pump housing is too restrictive.

edit: If you do run into that... at that point it would be cheaper to get yourself a 370z fuel pump housing versus switching to our twin walbro setup. I have not seen it done yet, but I will guarentee that a 370z fuel pump housing can fit a 350z with a hour or two of simple modifications. If you sent me one, I would be willing to make the alterations to it for you to make it a drop in assembly. That offer stands for anyone.. well anyone who is the first to ask me to do it.

also BTW in my 370z i did not upgrade the wiring. If I were in your shoes, I would try it on the stock wiring first. If it became an issue while tuning it wouldnt take long to do a hack job power wire setup off the battery to finish tuning and then do it proper off the dyno.

 

I have a stage 1 system

 

I have a 4 liter surge tank that I'll be selling soon. My original plan was to run a fuel line from the OEM fuel tank to the surge tank, and then an external fuel pump to push the E85 up to the front. PM me if you're interested in tackling the E85 project in a different way.

 

you should post pics of that surge can.

 

I'm waiting on my FS thread to be approved and then i'll post the link to it

 

might be beneficial to run an 8an supply line to remove that stock hard line. that will help your flow rate to maximize the pump as well.

also, with just running a single walbro 255 on my car those stock 20gauge wires got VERY hot to touch when i would let the pump run and the car idle while doing some wiring. 20gauge ran that far back to the pump will have some considerable voltage drop off. Not saying it won't work but 10 feet of 10g wiring back to the pump with a relay is worth the 30-40$ you will have in parts.

 

Here's the link to that surge tank I had built

I made another thread about the problem I've been having at 5500rpms at 550 hp. I don't think using the aero motive was a good choice for e85 lol. Shoulda went twins but My tuner said I had enough pump for my goal around 600 hp. I hit 550 and then it starts to break up and misfire around 5500 rpms. I'm not sure but I'm guessing its a fuel problem. I'm prolly just run 91 and stay around 500 I guess. I just want my car back lol

 

hmm, not sure what your tuner is used to working with but 600hp on a single pump with e85 is just plain crazy talk. I'm shocked you managed to get up to 550hp with it. If it's running out of fuel how does he not know? It should be showing up on the a/f easily.

 

I have no idea...I'm calling tommarow to figure this all out. I just want my car back. Ci don't even care about 600 hp anymore. Il run 91 and deal with high horse after deployment.
