i agree w/ that, but this guy doesn't care

 

I'm hoping to hit 450 on fuel and my mods aren't that extensive...the 14mm head is the only real trick.

 

Well I think I would like to be a P-Pump then.

 

From another sites 94-98 12V FAQ:

Is it really that simple?

 

Yup...but you're evil.

 

So I was wondering something... assume for a moment the amount of fuel injected is the same for a ve and a p-pump. Will the p-pump engine make more power because of the much higher injection pressure?

 

Don't forget horsepower is a formula where RPM is a factor. P-pumps obviously keep moving lots of fuel as RPM increase. A lot of p-pumps make peak horsepower where a typical VE wouldn't be making much power at all.

 

With a higher pressure, the fuel will atomize better. As fuel burns from the outside in, the smaller the droplet the faster it will burn. So, theoretically, the less fuel you can push through the injectors in order to get the same power.
So yes, if you were to push the same amount of fuel through each pump, and if the injector orifii, (?) were the same size, the P-pump should make more power as the fuel will burn more efficiently.
But, as JBradley pointed out, power is more closely related to rpm's than injector pressures. In saying that, it's ALL related isn't it?!

 

I'm wondering why John's evil...?

In 6 more posts you'll be the evil one!

 

That post I quoted must be for a manual transmission truck.
