my truck with everthing in my sig. only ran a 15.9 im confused shouldnt it be faster then that?

 

You running a stock transmission? Stock Turbo?

If your trans is slipping thats where all you power is going.

 

what was ur fuel pressure, cause u could also be running out of fuel. also, boost leaks will also cause slower times.

 

tranny is built with a billet triple disk and its the stock hx35. my fuel pressure is about 6 psi at WOT

 

thats to low. ideal, it should never drop below 10 psi. might look at getting that upgraded asap

 

That fuel pressure isnt good for the vp44, but it should still make power, good power.


That seems really slow to me, tell us more. What boost, EGTs? Did the motor pull hard then fall off or was it a pooch through all rpms?

 

my boost was about 35 all the down the track and it shifted great and motor ran great all the way my egts when i got to the end were about 850 so not to hot for the injectors ive got im so confused

 

boosted launch in 4hi? I went 15.06 in my 01 with edge juice and stock injectors and the hy35. But your fuel pressure is slowing you down too. Are the backdowns set low on your juice? That could be limiting you too.

 

That 850 degree egt seems really cold for 150s and the edge, either the box is defueling or that low fuel pressure is killing it.

The duelly ran 14.9 to 15.0 with the edge comp and 65hp injectors with a stock lift pump, and thats about 4psi at the pump, (I know), and we have a hard time getting it to hit 30psi boost, egts in the 1100s in the 1/4.

 

yeah, I'm with moparious...if it's a stock Edge Comp, then it's starting to defuel at 2700 RPM, so even if the truck is trying to pull past that, it's not doing anything. Tire size might have added about a second to your run too...my quickest time at the track, with a manual and my current mods, 4hi, no boosted launch, was a 16.65 at 95 mph....the tires and no launch were what killed me, but I'm running a TST Comp, which doesn't defuel until 4500 rpm, which I can't hit anyways. I did peg my pyro out at 1600 on the gauge, by the time I was getting close to the end.
