Jdm's Fuel Rails
 

Can anyone vouch to any performance increase using JDM's fuel rails with a boost senesitive regulator? I would suppose the regulators are adjustable allowing for increased pressure for nitrous applications. Any performance gain?

stock is boost sensitive also, the only thing you gain is a stock fuel rail with an adjustable boost sensitive FPR. Been there done that.

The fuel pressure regulators we use are adjustable, Genreally for most all high horsepower applications (nitrous, Built motor, KB,etc..) we set them at 32lbs idle and take care of the rest dyno tuning. You can set them higher if you please but thats how we do it here. This setup is suggested for high horsepower applications.

I've been debating buying an adjustable reg for @ 3 years now,
The one I've had my eye on says: You can safely adjust the fuel pressure, upwards from 40 lbs. static to 42 lbs. I liked it because it simply bolts on to the stock rail.

But over the years I've come to realize you can run well up to and over @500 HP and have no fuel issues with our stock system, if your running an Eaton and the late model MAF. My A/F was 10.1 at 5500 RPM, well over 120 MPH on the Dyno and made 500/600 +, so I guess I was right.

HOWEVER I believe for aftermarket S/C users and built Motors pushing well over 15 lbs of boost, it's a smart and prob needed mod to go to larger pumps, injectors and or an adjustable reg.
BUT when making power with Nitrous (instead of a Big S/C or major Boost), and spraying 2 to 1 ratio of Nitrous to Fuel, I've proved that there is plenty of fuel available with the stock system. Next time out I will be @ 525 + RWHP and approaching
650 ft lbs of Torque, if I make it through the run I guess we'll know it can take even more :lol:
If not, I hope you guys are in a giving mood, comes the Holidays hehehehehehe.......

just thought it was funny that he basically stated the obvious.

"The fuel pressure regulators we use are adjustable, Genreally for most all high horsepower applications (nitrous, Built motor, KB,etc..) we set them at 32lbs idle and take care of the rest dyno tuning.

Generally for most all................

Just got a laugh at this overall general blanket statement. :devil: Any detail on this product?

Generally for most all is JDM speak for:

sometimes always most (maybe)


:lurk:

exactly
 

:thumbsup:

Oh yeah, and JDM fuel rails are the greatest.......or something

Why is it that everytime someone asks a question about something from JDM, everyone automatically jumps in and bashes them? The guy didn't ask for a f'king commentary about what happened between Jim and Gregg.. so answer his question or move the f'k along. :thumbsup:

JDM did answer the question........kinda maybe most all some of it.:devil:

Re: Re: exactly
 

You mean the part JDM is selling is a stock F150 part
available at any parts counter nationwide for prolly
less? Wow! Will wonders never cease!

Who woulda thought to make money of off Lightning
"Brothers" that way?

One way Jim could stay outta trouble is to tell the truth.
As far as I know, the "I used to work for Ford" is the Big One
still to this day. A FoMoCo W-2 woulda put that one to rest
years ago.

Tackling one of the experts in his own area of expertise
did seem a bit odd to me. But then every time Jim gets the
chance to rail against the competition, he never misses it.
Gregg just had YEARS of frustration built up, and I totally
understand that. :)

Re: Re: exactly
 

So the JDM fuel rails come with a removable Aeromotive regulator rather than a non-removable Ford regulator? Any benefits in this other than the former being boost sensitive? How much is the Aeromotive unit and can it easily be added to the Ford part fuel rails?

Also, how about some part numbers?

Re: Re: Re: exactly
 

Yea theres benefits. JDM making the cost back 2 fold. :devil:

Re: Re: Re: exactly
 

Your missing the point. Both are boost sensitive. The Ford one is NON ADJUSTABLE. Nor can it be removed. You can probably buy the Older model Ford part, and a regulator and achieve the same results, if you must squeeze your nickels. I have no problem paying a couple bucks to have a tuner install his set up. Just like the traction bars....you can buy vendors rancho bars, that they have put time money into developing brackets for, or you can buy racho bars and make your own brackets. I am to the point where I make a decent amount of money, so I don't mind paying for something that I know to work. When I was in high school, I would have monkey'd around and made my own parts. Thats cool, its just not for every one.

Re: Re: Re: Re: exactly
 

I'm not squeezing nickels here. I'm also not *****ting money away either. If it's a big hassle and something that isn't easily done, fine. I'll pony up the funds. For instance, I run JLP lift bars. I wasn't out to fab up my own brackets. But if it's something more along the lines of a $25 boost bypass-type job, then why would I pay my hard-earned money towards it? I'm not running a charity here.

And last time I checked, being a car enthusiast meant having fun with your car, not just buying everything and then paying someone to install them. If I wanted to do that, I would've just bought a Viper and been done with it. I wouldn't have chosen a vehicle I knew had an extensive aftermarket and a great enthusiast community. I love being able to get together with fellow gearheads and have a few beers while working on some cars. Seems to me like some rather sit in a Starbucks and browse over parts catalogs, then give their local mechanic a call. Doing your own work and fabbing your own parts doesn't make you a miser and it doesn't make your achievements seem like a high school hackjob. Looks like someone needs to sell their truck and go buy a Saleen or Roush....:beers:
