42s and the intercooler is on the way. Very Happy

Only 42s?

iansane · Posted: Wed Dec 07, 2011 9:51 pm Post subject:

Yup. Got a great deal on them and they'll be okay for my goals...

For right now... Laughing

2psi?

With injectors that small I figured 2psi was a safe bet on your goal!

iansane · Posted: Thu Dec 08, 2011 10:47 am Post subject:

When factory injectors are only 28s and not close to maxed out, I think this is a good start. Besides, I can always upgrade later. Very Happy

Why you gotta be crapping on my dreams, man!? Laughing

Cause I was running 30lb ford injectors (rated at a lower pressure) at 48psi and was at about 95% duty cycle for 330hp.

These are fords as well. LS car typically run around 58-60psi though...

Twilightoptics · Posted: Thu Dec 08, 2011 12:53 pm Post subject:

So maybe 400hp. LOL so 2PSI? LOL

OK, I know you are right Paul, your numbers just needed a little explanation I think. Very Happy

Everything you were running does take lots of power, and engines don't read books. Smile

95% at 330RWHP just seemed a little unrealistic without the additional qualifications. I was flipping Ian crap too.

Fact of the matter is, despite all we're saying, he'll probly be able to run close to or more than 400RWHP with those 42s. Which is nothing to sneeze at. Smile

Thats assuming he isn't running a raising rate fuel pressure regulator. If the fuel pressure is raised at a greater to 1:1 ratio to the boost pressure, then he has the potential for more power.

Of course...if he isn't boost referencing the fuel-pressure, then his injector size will actually go down once boost is introduced since the fuel pressure will have to overcome the air-pressure.

Rising rate is a must, but I don't know about running 75+ PSI on those injectors.....

So yeah, bigger injector to start, to overcome the pressure difference.

Have you guys seen the rising voltage fuel pump controller? Takes a manifold reading and accomplishes the same thing as a regulator by increasing the voltage to the pump to increase the pressure. Pretty slick and stealth.

That sounds like it may be hard on the fuel pump, overclocking it like that. Sounds like a pretty cool way to boost fuel pressure if your pump can handle it.

Variable resistor fuel pump relays have been out since the 80's. They are unreliable, and the slightest bit of corrosion or bad connection and suddenly you're lean.

Bad idea.
