One is significantly larger than the other, so what are you comparing them on?

 

Apples vs Oranges

 

Completely dependent on if the ID1300x will get you to your power goal. If it will, then it is a no brainer.

 

question for everyone... I am upgrading my Turbo set up.. going with a FullRace twin scroll and a GTX3582r running E85,,, I currently have ID1300 with a 450lhp fuel pump and inline pro fuel rail... what kind of numbers should i expect with my fuel set up? 700HP out of the question?

 

On 1300cc inj and e85 i would think 700 would be its uppermost limit. I would imagine 100% duty cycle would be hit in order to reach 700hp

 

so it would be a injector issue not a a fuel pump??

 

We have a really badass fuel flow calculator on our website you can play with to help here.

You will 100% be smart in stepping up to the ID1700's. Rough guesstimates show a fuel pump supply issue as well though. Looking at needing roughly 346l/h at 9,000rpm. The single 450 at 72.5psi (43.5psi base and 29psi boost) only flows 286l/h.

 

anybody use the 1050x ID's over the ID 1000? any difference?

 

I see.. what if i keep the 1300 and just get a dual fuel set up? or just a bigger fuel pump..

 

The ID1000's are no longer available, nor are the ID850's. The ID725's will soon be good too. We phased them all out in favor of the ID1050x. It actually has better low pulse width behavior than any of the outgoing three, and obviously flows more as well. It's also capable of 10bar pressure, which is ridiculous.

In short, its better than the ID1000 in literally every way. Like the rest of our stuff, in stock and ready to ship.
