Default ID1000 vs DW 1300 injectors?

I'm running a Revhard manifold with a full 3" DP and exhaust, Tial wg and genuine Garrett GT3076R. I'm looking to upgrade my current fuel injectors (RC 750s) to something that will support 450whp on E85 (preferably high impedance so I don't have to mess with a resistor box). And by 450whp I mean 450whp. I do NOT want or need something that will support tons more horsepower.

Current Fuel System:
Walbro 255 fuel pump
fixed rate FPR
stock lines
stock rail tapped with a fuel pressure gauge
RC 750cc injectors

I've done some research and the Deatschwerks 1300cc and Injector Dynamics 1000cc injectors seem to be my top two choices.

Which of the two would you guys suggest? I know the IDs would probably be slightly better, but I'm worried I might not be able to get to 450whp with only 1000cc injectors and I can't afford bigger (1600 or 2000) IDs... which has me leaning towards the Deatschwerks 1300s.

Any thoughts/input?

Well the DW is what I would go with running e85. You are right about pushing the limits of the 1000's. I was going to go with the DW 1300 but need a bigger injector with e85 pushing more than 500whp. I have not heard any negative things about these injectors.

Alanpikku made 523 on e85 on dw1000ccs on a ur kit. He was tuned on a dynapack Dyno. So I dont think you will have any problem hitting your goal with dw1300s.

I've read that they don't... which is my main worry. If I knew they'd idle as well as IDs I'd probably have already bought them, lol.

If you will be pissed if you end up at 440 instead of 450, then go bigger than the id1000s.

You should be fine with id1000s, but 450 on e85 is going to be close to the limit. Keep in mind that some people have gotten 500whp on the fb fuel pump and id1000s.

Yeah, that's true. I guess if I fall a bit short I could always upgrade to the FB340 pump.

500whp? Really? On what dyno? Seems like a LOT of people have very inflated numbers (everywhere, not just on s2ki)...

Its crazy how the price doubles when you go over 1000cc with Injector Dynamics..
they know you want big power & can squeeze extra money out of your addiction lol

Fullblown. My tuner said that wouldnt be possible on his, so who knows.
