A member here sent me a PM asking me what EFI system I had and why. I wrote this answer but his inbox was full so I decided to post the answer here.
Well I have 3 of them currently and will be buying #4 in the not too distant future. Here is a rundown with reasons;
1. Cuda:
Intake - Mopar 6 pack modified for a fuel rail
Throttle body/s - F&B 6 pack
Ignition - MSD 6 AL and Billet Distributor
EFI controller /harness - FAST EZ 1.0
Fuel System - Modified original tank, 1/2" steel lines (feed and return), external pump (came with the F&B system)
WHY - I went with this system because I wanted EFI and I wanted a 6 pack system. I built the car as a modern AAR type road race car. It has a ton of fabrication in it and I wanted a very exotic yet familiar intake system. When I bought this system, it was very new on the market and was a bit unproven, however the FAST system advertised that it was essentially "plug and play" and since I didn't know anything about EFI at the time it seemed like a good idea.
NOTES - The system functions as advertised and there is little to modify or manipulate which in the EFI world is a little bit limiting if you are trying to "fine tune" the system for performance, easier starting, etc. It does learn on its own and gets better every time you drive/run it.
2. Challenger
Intake - Mopar 6 pack modified for EFI fuel rails
Throttle bodies - F&B 6 pack
Ignition - MSD 6 AL box, Holley duel sync hall effect distributor
EFI controller/harness - Holley HP
Fuel system - Tanks Inc. EFI tank with internal fuel pump and filter, 1/2" aluminum lines (feed and return)
WHY - I built this car the first time in 2004, its an original 440 4BBL AT AC RT car. I had a traditional Mopar 6 pack system on the car since I built it but since I do not drive it frequently it was always a royal pain to get running with the carbs. I rebuilt them at least 4 times yet it never lasted and to be blunt it ran like crap. While I was about 3/4 of the way done with the Cuda I came to the conclusion that I had never finished the Challenger or at least got it to a drivable state. I decided to install the E&B system and thus I would have a BB and SB version. While I was looking at the F&B systems I stumbled upon FASTMAN EFI (Rich Nerdahl), I called him and it turns out he is an old school Mopar guy, more specifically a Hemi guy. He told me that Holley was the way to go and that he would sell me the controller system (I purchased the intake and TBs directly from F&B) and that he would assist me in any way needed to get it set up and working correctly. Therefore I ordered the distributor and computer/harness from him (drop shipped from Holley).
NOTES - This system with the Hall Effect distributor and HP computer is far more controllable than the FAST system but requires a lap top and an understanding of EFI systems/program to a degree. I got a very intense education on this subject after I got it but to be honest I really prefer it because you can control timing, fuel, idle, etc. through the laptop. Once you get your head around it, it is not near as difficult as it appears. Currently I do not drive the car any more than before but it starts, idles and runs better than it ever has not to mention that power is WAY up.
3. 52 Dodge B3B w/Desoto 330 Hemi
Intake - Hot heads 4BBL
Throttle body/s - Fitech go street
Ignition - Mopar electronic
EFI controller/harness - Fitech (comes with the TB)
Fuel system - Tanks Inc. tank with internal pump and filter, 3/8" fragola HP series 8000 lines (feed and return)
WHY - When I built this truck I installed a brand new Hollry 600 CFM carb; initially it ran great but like the others sits more than it runs. I took it out a couple of years ago and went and got gas. Upon leaving the gas station it began stumbling and puking; clearly the carb had issues. I got it home and messed with the carb a little and then it ran ok, however I was so upset that I ordered the Fitech system the next day. This was the cheapest EFI system you could buy at the time ($795). When it arrived I bolted it on, connected the 4 wires, installed the O2 sensor, installed the fuel system and fired it up.
NOTES - The trunk will start and run any time I want it to, it has a tremendous amount of power and runs great.
Bottom line here is that if I can help it I will never have another carb, EFI is so much better. Yes, it is more expensive to get set up but once you have it you will not regret it.
Hope this answers your questions, don't hesitate to ask me any questions you may have. Oh BTW, I intend to run a Fitech system on my 426 Hemi I am putting into my 70 Road Runner.
