Ok well the break in is done on the new engine & last night i got to beat on it for the first time. & I NEED more fuel! the truck is making great power but on the mid to top end you can feel the engine is just wanting more fuel. My egt's are way low (1050*) & ther is NO smoke once the boost is up, Not that I want smoke, but there should at least be a haze... My last dyno on the old engine with the same fueling and turbo it made 430 RWHP & 960 RWTQ on a NON loaded dyno, After the header I was barly able to hit 1380-1400* on the egt's Now Its making more power with the cam, CR head & head work but as you know flow goes up boost goes down. Im now down about 8 psi of boost from befor & down over 300* on egts & it wants more fuel. Should I start by putting a SO injection pump on or just buy some mach 5 or mach 6 injectors? IMO i think the injection pump is just not being able to keep up with the fuel needs of the engine. Please give your thoughts TIA

 

You could always stack a Smarty in there...

 

I could, but if im at the limits of the HO injection pump I dont think that would help me at WOT mid to high RPM range.

 

A 2000 5spd shouldn't have a HO pump. Did you put one on? I'm kinda confused.

 

Yes it had a HO pump put on it (not my choice)

 

Life begins at Mach 6's.

 

Ya im thinking SO pump to start with and than Mach 5 or 6 injectors.

 

any other sudgestions?

 

Would a hot rod VP help at all?

 

would a p-pump conversion be for you?

you could get some pretty darn good fuel out of those things!!!

 

yes a hot rod pump would help, But im leaning tord a SO pump bec they will support 600+ RWHP and would help with low rpm/boost smoke out put

I really want to do a P-Pump but at this time cant bec of the tree hugging state of CA that im in at this time.
