Pressure is controlled by the regulator on the fuel rail. It diverts excess fuel back to the tank.
I figured so but just wanted to make sure. That then simplifies things a bit.
Here’s the story on that; in order to make more power, your engine needs to burn more fuel. A small power increase can be realized with the stock fuel system by raising the volume efficiency as well as the thermal efficiency of the engine. Assuming that you had those things optimized, your engine would still need to burn a half pound of fuel, to make one HP, per cylinder, per hour. With your stock 14 lb. per hour injectors, you’re governed to roughly 105-110 HP max.
Ok, so following along with that little equation, the 24lb injectors that Mikel89us suggested before should work just fine along with leaving room for more power in the future.
Your ECU was calibrated for 14 lb. injectors, but it has the ability to compensate for slightly larger injectors. I think most of us 2.3 Mustang folks agree that 19lb. injectors are at that limit for stock calibration and maybe a bit on the rich side of things.[/B]
I had read that before as well, I was considering 17lb before I decided I was gonna go all out.
I think the injectors from the Ford Contour V-6 SE are the best match I've tried. They will give you enough fuel for 130 or so HP. I've built a few Lemons engines for racers and managed to eek out 136 HP with the right mod’s “mostly stock motors” with the contour injectors, but the same engines with a proper tune and larger injectors made over 150 HP.[/B]
So I would want larger injectors than the Contour? Well that gives me somewhere to start.
“The Quarter Horse is by far the cheapest legitimate tuning software+ tuner that I know of. It takes a little effort to learn, but I think if you start with the tuning stuff first, you will end up with a better running car with enormous potential to make power.
You can buy a chip and a J3 adapter for less( $60)and have a shop tune your car (most charge $100/ hr) But every time you make changes top your engine, you will have to go back to the shop. I would save up for the Quarter Horse. Once you have it, you can still take your car to a tuning shop to have an initial tune put on it, then learn about tuning and buy Binary Editor 2012 later.
Ok, so Quarter Horse first, Add all needed mods, then find a place to do a tune, and then if still needed buy the editor? sounds like a plan. Now off to do more research on the correct injectors.
Edit: Well I found some 24lb/hr injectors, but I seem to have hit a bit of a dilemma. I found these injectors from Holley EFI that are sold individually for 47.95... so all 4 would clock out to 191.80 with free shipping.
Fine, fine, but I also found these from Ford Racing, which honestly, sound like a better injector. The price of these is 179.99 plus free shipping as well. the kicker is that they are only sold in sets of 8. I can not for the life of me find them in sets of 4.
So I guess the question is, would the ones from Ford Racing fit? or should I go with the ones from Holley? If the ones from Ford Racing do fit I can just sell the other 4 I suppose or just keep them as spares if that doesn't work, so I am not to concerned on that front. However I may have missed some and there may be better ones out there.
