If you plug it in
here, it looks like it is 57.2, that was a little more than I expected, but it is still not a lot. Nor do I fully believe those numbers. Without actual flow data from the injectors it is all somewhat of an estimate.
It is also significant in keeping proper spray pattern, especially under boosted conditions.
Where does this come from?
The injectors will see a fuel pressure difference of 20psi regardless, so if there is one optimal point (which I don't argue) what does it matter if I hit that at 4#'s boost or vac?
I really just made that comment before to state the fact that it will not run out of fuel at 39.5psi because the motor would be at a vac (ie part throttle), whereas I am worried about WOT.
I do appreciate the link, I should read up on more of this stuff.
Paul, nothing on my car is "ideal". Hell I have been driving around with the ar on now for 5 months or so, pegging the maf by 2k, and 100% duty on the injectors by 5k. I am not saying any of this is right at all, but I also refuse to dump 20k into a car to ideally hit 350rwhp. I'll just slow the blower down if I need to make the car safe.
Non-the-less, this is all good discussion and something new for a change.
Hell, I remember before I ordered the AR kit that I told DD if I was going to need to buy bigger injectors right any and run a second fuel pump that I didn't think it was a wise decision for me to make at the current time.
Well, it turns out that I do need that stuff to keep it "ideal"...
And I get such great gas mileage right now as it is.
I don't remember when exactly I went from 26mpg highway,17city to 20hw, 11 city but it sure does it. And now my idle is stuck ~1500 which I am sure helps. Nothing like holding the brake to drive under 45mph.
Sorry, I am venting now, most of that stuff I should be able to take care of next week. These damn finals and hw are just pissing me off. I just want my damn degree already.
So to sum up, the 60's are going on, my thermostat housing still leaks, idle sucks, pia to drive the car, it is dirty and torn apart, swaping injectors is going to be an 6hr job with the ar (new kits will be easier) got a system dynamics final tomorrow morning (DD that is the class about transfer functions etc, which I am kickin as in), this dam english report that is due tomorrow and a complete was of my time is pissing me off, but I have a date on friday so it is all good.
Cheers,
