What is the upper limit for ID1000s?

[31BCobra]

I hear everyone talking good things about ID1000s on e85. But nobody really talks about (maybe nobody knows yet or I just missed it) where they begin to max out with a standard base fuel pressue. Anyone know?

Right now I am only planning on my 2.3l Whipple spinning as much boost as possible, high 600s low 700s. But I plan on going much larger and further in the near future and would like to only have to build the fuel system once. Anyone know a specific limit to them?

I have a feeling they'd be maxed by around 800whp on e85. sounds like some 1300's might be a better option depending on how much further you plan on going down the road. On e85 1300's would still be fine for your 6-700hp setup but will probably handle 4 digit numbers when maxed out.

My tuner told me around 800 to 850 on E85.

Maybe I will just call around 800 the limit of my future plans. :-D
Going to be hard for me to justify to myself the extra $1000 for the 1300s. Thanks for the help guys.

Have you tried using the calculator on ID's website?

Do it right and go return style. Then you will not have to worry. I am just shy of 800rwhp on E85 (Tested E92) and FRPP 80lbs with base at stock psi. Have a bit of room left and drives very stock.
