i'm looking to convert the car to e85. during race season, the car could be sitting for a month or so. and a few months over the winter. who make makes stainless injectors and what's the largest size

 

Fic 1650cc high z

 

thanks.

looks like ID1300 are also all stainless internals.

but for the Price you may as well get the Fic 1650.

 

I have connections for Injector Dynamics

 

Well Then have them hook you up with the new 1700cc that i have heard about!

 

Depending what power you're making, the ID1300's don't actually flow 1300cc. I think it was mrfred that did some testing that showed there were really close the FIC 1100 Hi-Z injectors.

I currently have FIC 1650 Hi-Z in my car, and they work very well.

 

the ID2000 is only $50 more than the ID1300.

 

hows the drivability and idle with the big injectors? SD conversion or not? i'm not planing to make more than 500 whp on e85. most of the time i'll be at 320 whp ish for nasa TT3 class.

 

500 whp on e85 is right at the limit or a little beyond for fic1100s and id1300s running stock 3-bar base pressure. i really wish someone would offer a true 1300-1400 cc/min high-z injector. with that said, fic2150s are an amazing injector for drivability. it took a bunch of work, but i now have my evo idling at 875 rpm at least as good as my fic1100s did. they're not stainless, but the point is that the bosch high-z injectors set a new standard for combining high flow with drivability. i've heard good things about the 1650s, but i haven't bothered to try them yet because dialing in the 2150s wore me out.

 

If one has upgraded his fuel system such that it supports higher pressures and has sufficient flow capacity, this issue is solved simply by raising the pressure.

Remember what Tony of ID clarified on more than one occasion, that being much of the benefit of the Bosch EV7 injectors with respect to atomization, driveability, and fuel efficiency (and power) comes with running them at increased base pressures.

 

Mostly agree, and that's what I did when running my FIC1100s at 500 whp. They worked even better at 4-bar than 3-bar, and at 500 whp, I was hitting ~90% IDC.

Of course you know there is one limit - higher base pressure moves the pump(s) into lower flow territory. Depending on the boost level, it can be possible to reduce flow to the point of not being able to support the target whp. It was right at that limit for my E85 Walboro 400. It was running into the high pressure relief valve. With the right parts, it can be managed, but wanted to point it out.

 

The FIC 1650 Hi-Z's have been great on my car so far. It didn't take much work to get them idling at +/-2%. And then your low pulse width linearization table made them a touch more stable after tweaking the latency.
