Parameters:

93 Octane PUMP GASOLINE
Supercharger Pulley: APR 2.7" Upper, Stock Lower
Room Temperature: 72*F
Fan: No fan, someone knocked it off the dyno and broke it lol.
Dyno: Dynojet
Tune: VERY conservative - pulled timing and ran a tad rich for nitrous use.

The stock engine is the limitation.

I was losing fuel pressure bad on top so these numbers were obtained under 5800.

Dont you have dual pumps? Is one pump just for the extra needed for the no2?

yes but the second is being done a little differently, I have a pretty nice dual in dual out filter setup going that im in the middle of installing.

I did the filter install last night and kind of hob kobbed it up there with fittings I had so i could dyno today.

Once I get the fittings I need it will be good to go again.

so the single 255 is not big enough for what application? i thought it was going give the 4.0 enough fuel for stock motor limitations

No, Ive witnessed pressure drop for a long time now which is why I went duals.

 

[blastap]

are you going to run them in series?

 

[5H4D0WD347H]

are you going to run them in series?

No.

The primary is run all the time while the secondary is kicked on under load.

They are parallel.
