looking for Fuel Rails

BlueSatty · 02-24-2004, 04:29 AM

I am looking for a aftermarket hi-flow fuel rail. when I upgrade to a performance motor, it will suck in a lot more fuel, a lot quicker. Oh, and I am also looking for some larger injectors. any one have some ideas, or a something to point me in the right direction?

the injectors you can buy from summitracing.com

What kind of shot are you going to be running and what are you doing to the block? What else are you going to be using to control the larger injectors, or are you just going to go 10% higher or something?

10% is exactly what I am looking for....it will be running a 250 shot on the track...the block is just be bored 20 over. I was not aware that I needed to have a different/more powerful control for injectors.

For 10% you should probably be okay. Are you running a wet or a dry kit? I am assuming since you have NX Nitrous EFI listed that it is wet, but just want to be sure.

If you're just going up 10% in size, then some 21# (220cc) injectors should work fine. Just double-check the fuel pressure assumed in the injector flow rate specifications to be sure that you're not just getting the same size injectors.

Running a 250 shot, I would definately recommend some form of fuel control computer that will allow some tuning. Tuning with just an adjustable FPR isn't really the best way to go about it. Go to turbosaturns.net and go to the forums. Down at the bottom they have a room for discussing the MegaSquirt -- a standalone fuel injector controller that you can tune the maps on. I'd also check into replacing the fuel pump and getting a better FPR, since with a 250 shot on a built engine, you're probably reaching the upper limits of the pumps capacity and just begging for pump failure.

Also, keep a close eye on your spark plugs -- even two stages colder might be detonating at that level. Have you given any thought to direct port? Saturn Motorsports may not have the direct port KIT ready, but they do have everything you would need to run the injector rings and such. Direct port will be much safer at that level (and much more consistant).

blue, you should get some pics up, id be interested to see some-- and video would be awesome too

I will be going for direct port after I break in the motor and all that. I have not even finished building the motor yet...I still have a way to go.

it is a wet kit.

I have some videos...but they are a little old...where can I post them? here is a picture.
