I am planning on doing this myself and I know a few people were interested so I'll be the Guinea pig again

I am $950 deep into the setup and will update this thread as I install it within the next week as well as document its ability to sustain my goals. This unit is good till 900 on e98 and 950 on e85 to the tire and well over 1k with ms109/race gas.

Nice will definitely be looking at this thread in the future after I go FI. Will definitely be wanting to go E85.

Ask your inside source where my Lambda was on my last log with this system on E85.

You need lower base fuel pressure and id1300. Trust me I have fought this for the last 2 weeks.

I have the ID1000 for now. Was hoping to not need the 1300's until I go full retard.

Did you switch to a triple pump or do you still have this system?

This is similar to what I installed on my car in 2014. ;)

For me it has worked great.

I did swap to ID1300 and a VMP BAP set to 17V a while back though, and that has helped steady out the fuel supply at high RPM.

I am updating the system with VMP Rails, -10 feed and -8 return with (3) 465s soon though.

Well shit I was going to sell my JMS BAP but Sai said I didn't need it. Should I refund this guys money that bought it? Lol

I am not going to make that call for you, but I will say that my system with the ID1300 and the VMP BAP made it work better. I was running out of fuel before I swapped to those. I have never dynoed my car, but without the BAP I was able to go about 147-148 MPH at 3900lbs.

Well fuck me sideways I just sold my extra VMP BAP LOL

My car is 138-140 right now and I plan on keeping it at 140-144 for now. I was hoping to start funneling money into a forged rotating assembly.

With base pressure at 55 and 15 psi boost it wouldn't work. Sai told me the pumps bypass at 70 psi so try lower base pressure. When I went to lower base pressure to increase fuel flow the injectors came up just short. Very close .83-.84 lambda with more commanded and no response. I put in twin 465 pumps at 55 psi base and the problem was solved with id1000 still in.

Fore says twin 465 support 1000+ on E85 depending on injector.

Did you try wiring up a BAP to give yourself a little more room? I just asked him about my goals and he confirmed it will work. Goals are 700-725 on 11.6psi daily and 825-875 on kill mode. I wonder if something is different with our FPDM vs the outgoing 11-14 unit

With this kit you are only signaling off the fpdm. It does not come into play. In my experience 700-750 was ok. When I turned it up it came up just short. IMO you better have a BAP close by to reach the kill mode goals you have.

It will make 900+ on turbo cars. It depends how much HP the blower is eating up for the limits of the kit on supercharged applications.
