Cliff notes at the bottom.
Hello - I would like your expert opinions on the following setup. I am trying to put together a list of what I am going to need to meet my goals using E85 and I would rather not buy parts twice if possible. The "Endgame" plan is to be pushing a max of about 550RWHP on E85 Via turbo boost on a built bottom end. But, I am starting with my stock bottom end and around 450RWHP as the goal. So I am trying to calculate the fuel injector size close enough to meet both my requirements if possible. Should the following setup be OK at 450RWHP on E85 and still provide me with enough fuel for 550RWHP on E85?
Stock Rails
Stock Lines (May just bite the bullet here and go bigger)
New (stock) Fuel filter (If I go with bigger lines I'll get a billet filter)
2 x Walbro GSS342 on stock hat (W/ FPDM "Wiring Mod")
Ford Racing or Siemens 80lb/hr injectors
The boost will be provided by a as yet underdetermined turbo kit with a PT6262 Precision turbo. The reason I picked a relatively small turbo is because this car is a street car first and a race car second. So I would like as much response as I can get without "maxxing" the turbo out when I reach for my future goals. I think this turbo with a billet wheel will give me what I am looking for and still be "in the meat" of the compressor map.
So far I've done a good bit of homework and the most accurate number I can come up with, given a BSFC of .5 and that E85 generally requires about 40% more fuel, is that 60's are going to be maxed out at 460 crank HP at stock rail pressure. So, this means to give myself a 15% margin on the injectors I'm going to need at least 80lb/hr injectors. I would rather keep injector duty cycle at or under 85%. Will I be able to crank rail pressure enough, given that I’m using twin GSS342's, to support 550RWHP or am I going to be stuck buying another set of injectors when its "go time"?
(Calculator I used: http://www.injector.com/injectorselection.php I also used Cokry Bell's "Maximum Boost" to find the original calculations I was using, but the online calculator was much more simple.)
Cliffs: Will the small parts list after the first paragraph provide me with enough E85 to make 450RWHP on the stock bottom end and then 550RWHP on a built bottom end in the not to distant future?
Thanks!
