My objection (and I would have thought it was pretty clear to anyone of average IQ) is that one person saying '440s are what you need' three times and you saying 'he's the man' does not a conclusive argument make.
If you guys can't back up your arguments then don't be surprised if I make fun of you.
Apart from some theoretical internet calculator, I haven't seen you back up your claim either.Quote:

Thats the 4th time i've stated that now, has it sunk in for you yet?
The concept is really quite trivial, I'm astonished you needed to start such an argument over something so trivial... oh thats right, you have a set of 550's for sale :p
What more do you need? And it's way more than you've presented.Quote:

As for arguing, it takes two to tango. And only one of us has tried to bury the hatchet.
I'm more than happy to bury the hatchet. In fact, I don't really qualify this as an argument. I just needed to make those few points.
back to business:
I work with formulas every day, and let me tell you, junk in = junk out.
I can probably make that formula spit out an injector size of 310cc if I tried hard enough.
Also, you are running a bigger displacement engine and much larger turbo than the specified GT28. I can see you definately needing larger injectors, agreed, however, the baby turbo in this topic won't dictate excessive injector sizing.
Another point to consider, is that (i assume) this is a stock motor, stock rods/pistons etc, and hence anything over 250whp is likely to start melting stock pistons, which leads me to conclude, the amount of boost in question here is something in the 8psi range. Perhaps the orig poster can clarify further, as per Dyno Dave's comments.
He isnt going through with the turbo conversion anymore.
Cool, let's agree to have slightly different opinions. I understand GIGO but I don't think what I entered was garbage.
With regards to melting pistons, that happens when you have too high cylinder heat. The cause of too much cylinder heat is a lean condition. The way to avoid a lean conditions is???
More fuel!
LOL Well I guess 440s will be big enough then. ;)Quote:

WTF? where can I get some of that shit you're smoking?Quote:

Why are you so aggressive? If you disagree with my post why don't you say so and explain why?
I'm running an 11:1 compression engine with 7psi so i have a fair deal of experience with tuning for NA type engines for FI. You can only pull so much timing before you are throwing out the baby with the bath water. If you've got high EGTs and your injectors are at 90% duty cycle then they are too small.
Rather than leave the topic alone, why don't you leave the attitude alone and try and discuss this like an adult?
