#279, "fuel needs are different for each turbo (revisited)" In response to In response to 4

I can't se this as true, Hoot.
I think we've already spoken to his one time, but I just wanted to get your grasp on it.

So, are you saying a Super 20g and a T-25 both pushing 10 psi are giving the same amount of hp? That's in effect what I think you're saying if they need the same amount of fuel per level of boosted psi. Fuel = hp. Simple truth is that each turbo has different flow rates called CFM's. The T-25 has a ridiculously low flow rate, whereas a race turbo such as the Super 20g has a laggy high, high flow rate. Each would hit 10 psi at different rpm's, but the difference in hp and needs for fuel would be enormous.

All of these things are contributing facts to what makes a turbo different and unique to someone's turbo application, but I would add that fuel ALSO needs to differ uniquely to every single turbo application as well.

That's true and also the turbo and compressor capacity(the amount of air the turbo can hold and push through it's compressor) Since a T-25 needs only a little bit of air to fill up it's compressor and turbine blades, it spools quickly and needs smaller amounts of corresponding fuel at a certain level of psi to create your car's most efficeint stoichiometric(sp?) ratio.

I respectfully disagree b/c of my previous comments. I look forward to your take on this Hoot.
Therefore, it's my opinion that the T04/03 turbo would need a "different" amount of fuel than does the S-16g. Albeit maybe a small amount, if each turbo has different flow rates, in which I'm sure they do, they will also need different fuel pressures.
