Race systems FAST EFI systems allow you TOTAL fuel control from hot street/strip cars like the Turbo Buicks, blower Mustangs, NHRA Sock Eliminator cars, 8.90 & 9.90 Super racing, Fast brackets, all the way to 2500 Horsepower Pro-Mod type cars.

For nitrous engines the XFI can control your nitrous system activation (external timer or RPM and/or Throttle Position) and timing retard for up to 3 stages.  It supports wet and dry systems. In the dry mode the FAST ECU adds the fuel and the nitrous system does not require any fuel solenoids etc.

Based on MSD crank trigger ignition - works on GM Ford, Mopar

Team Kelley EFI Installation

The FAST system is really cool. It picked me up about a tenth over a well worked Rupert alky 1250 with a ported Edelbrock Super Victor and 2" super sucker. I would expect most folks to pick up 2 tenths. My car is a 540" BB chevy RED with a best of 7.47 @ 179 on a super nice day.
 
Over the July 4th  3 race weekend at Atco, I made 13 runs and when I throw out a couple runs because of high winds and 1 tire spin, I have 10 time slips with the 1000' within .02. This is with 75-98 degrees temp, humidity from 40-90, track surface temps above 150 and the wind.  I think that is very consistent. There are several slips identical and 5 within .009!
 
I am using alky, the belt drive Enderle pump I had, a Areomotive regulator set to 60#, a Holley Manifold, 160# injectors, the 2200 CFM throttle body, and fuel table from my supplier - Advanced Performance.
 
It went on easy  - the only pain was reworking part of throttle linkage mount (which was odd-ball because I had the 2" super sucker on top of my scoop mount plate) and with the fuel table I received I went right out and went a .05 faster than the previous week while my son and brother slowed up .05. Subsequent weeks validated the .10.
 
I tried Super Comp two weeks ago after not playing throttle stop for 4 years and in two runs I went 8.91. With the carb I had to hunt around for a month to stop it in a spot where the fuel curve was pretty flat. With EFI you just total flatten it when the stop is on. You bring up the screen and its like a Excel spread sheet with the injector pulse-with in cells separated by 500 rpm increments.
 
So, needless to say I am quite happy. The price tag on my system is about $4100 without the pump.
 
Although it's expensive, I'll never outgrow it. It will work on everything from small block to big-chief gas or alky. In fact I intend to put N2o on the car in September using the FAST to trigger the stages and add the fuel (Alky only). I will switch to gas in October and back to alky for the Florida races simply by changing the fuel table with my laptop.
