Are Modified FPDM's a joke?

[Zack]

I know of several Marauders and Mustangs running around with dual GT pumps and the stock FPDM....never had a FP issue, never had thermal shutdown.

How many actual documented cases of failure have been reported?

Seems like a hoax to me, thoughts?

I was just trying to research the same thing Zack. I have been for the past few days now. It seems like i keep hearing and seeing people running without them and havent had any issues. I just picked up some GT Pumps and with all this talk about thermal shutdown its scaring me into spending 225 on a modded FPDM and i really dont want to lol...

I see a lot of guys are cutting and splicing in dual stock FPDM's but then your altering the factory shit and IMO thats hack and will only hurt the resale of your car.

Hopefully some more people will chime in.

Good question. I have a stage 2 FPDM. I was told that my GT Pumps and KB Boost a Pump require more amps and voltage then my stock FPDM can handle. That's just what I was told. I hope that's correct, or I wasted money.

Interesting, I never believed what I read, but GNXS and I ran KB BAPS with stock pumps and 60# injectors and it supported both cars up to 650 hp. I can't remember if Larry ran a updated FPDM, but I didn't. Datalogs showed no major issues, but when you get to the higher point, upgrading at that point would be recommended.

I could see it needed in a road course event or standing mile when the engine is at WOT for extended lengths of time.

Normal driving with occasional bursts of speed is not gonna put stress on the FPDM, IMHO

I've been running stock FPDM on my car all the time , I just removed the plastic cover so it doesn't get hot inside there.It was on the car with twin SVT focus pumps and KB BAP for 3 years no problems, I have twin GT pumps with KB BAP still running stock FPDM now , have this set up for over a year ,never had any problems. I have spare FPDM and FRPS sitting inside the truck all the time ,just in case you never know.

I took the cover off my friends stage 2 FPDM and I didn't seen any difference between his and my stock one , looked like nothing was ever touched in there.
