EB fueling.
Since the Livernois thread was getting jacked by this I figured I'd start a new one. I was around a group of mazdaspeed guys (2.3 DI turbo) this weekend and was able to see some of the development on that platform. All of these guys had larger turbos than stock (GT3071R to GT3582R) but fueling was handled by upgraded HPFP and "5th port" injection. The Mazda guys upgrade their pumps for higher pressure however they only get to *barely* over what the EB 3.5 is at stock. Also, one of the guys who distributes a TON of turbos / turbo kits took a hard look at the turbo on my EB. They all came to the conclusion that it is most likely a Borg Warner EFR (or derivative). They were also impressed that a 4x4 SCREW could easily pull 120mph (GPS on private ranch road) with a lot left.

The idea is to keep the injectors somewhere around 75% duty cycle. All of these injectors will go above 100% duty but it's not that great of an idea to rely on it. You can count on having turbo upgrade option(S) by the end of the year.....and when that happens, gonna need more fuel.

JMS says its out of fuel pump at about 60 rwhp over stock.
Upgraded HPFP's aren't an option at the moment because the lack of availability and the likely high cost if one ever does become available.
7th injector kits were all the rage a few years ago in the turbo Buick world. I think something like this would be easily adaptable to the EB. However, in the turbo Buick world, the Methanol kits have largely replaced the 7th injector idea. You get the extra fueling you need, plus a lot of detonation resistance. You can run 30 instead of 20 psi boost with supplemental Methanol.
I personally don't like the Methanol kits because problems with the fuel system don't show themselves until it's too late.

We claim the quickest Gen IV SHO, which runs 12.1 @ 117 mph and it's not even close to being out of fuel system with 390 WHP. This car was tuned with less than 200 miles and has over 35,000 with a lot of track passes. Keep in mind, these make a lot less power in stock from than an EB F150... We have another that we recently finished with upgraded turbos that makes over 400 WHP and again isn't close to maxing out the fuel system. This car has over 70,000 miles and a lot of track passes and was also tuned when new.
