I am going to get a retune. I am currently making 340hp on 93 at 7 psi. I want to switch to e85 and go for 500hp. My current set up is ID1000, aeromotive 340 pump, stock line, stock fpr and stock fuel rail. I have a ilp stage 2 kit with a pte 6262bb turbo, ACT 6 puck and hdpp, and arp head studs with oem head gasket, aem boost controller and wideband. LJ from full blown motorsports did the first tune and I will be going back. He said he did a tune on a s2k and got 500hp on e85 with ID1000's at 90% duty cycle.

Just wondering if any of you see a problem with running +20psi on this setup.

 

20 psi will not work. You don't want more than 85% duty cycle Imo. Get yourself some 1300 injectors and you should see 500whp. Anything more and your going to have to go 2000 injectors or higher fuel pressure.

profile says 06, may need to convert to return.

 

I was in the same boat. Getting ready to return my id1300 for id2000 and running a walbro 450 e85 pump. I'm also aiming for 600. But didn't want to have my pressure maxed so no choice but to go bigger injectors. I would definitely get bigger injectors.

 

You will absolutely need a fuel return setup...I just ran out of fuel on my 06 at just over 400whp (Dynojet) on a stock pump and ID1000's on 93. Just bought the SOS return system myself.

 

What exactly is unsafe about running a high base fuel pressure?

 

arent there guys on here making 500+ with id1000?...why wouldnt that work? i know for sure joeyballs did it he was making 640 on 1000's

 

Well from the info I gathered if I maxed my id1300 out at say 85-90% with a single pump I would be around 500-530whp. This is the reason I'm going to id2000 so it wont Max the pump out. Higher pressure will starve the pump up top I'm told. Now with a dual pump setup I think it would be fine.

 

Joey was also running 110 octane I believe not E85. I think at 500 you will need a return system on the 06+. The reason I presume they say you don't want to be running more than 85% if you have a random problem with your injectors and it leans out because your running such high duty cycle, you risk the chance of damage.

 

Got mine just today man
