Current setup on my 2000 vp drag truck is:
Edge Competition juice with attitude
.093 connecting tubes
Stock lines
Stock sovp (possibly cracked diaphragm)
Fass 150
Fuel cell
Industrial injection 6x.016 injectors
Htt htb2 62 over a bullseye s480 with a race cover
On3 performance inter cooler
Head studs
Stock head gasket and internals
Dropped rear end 6.5 inches with a leaf under the axle conversion (trying to dial in my launch and take off at the track and get better 60' times)
Ats 2wd trans with a modified dtt fuel manual valve body with a ratchet shifter
Truck last weekend went 11.93 @116 mph in the 1/4 (1.9 60 foot)
And have dynoed a best of 749 hp last year
Truck weighed 5800 pounds with me in it last weekend when I ran the 11.9
Trying to push a stock vp as far as possible before upgrading it it seems like going down the track it would clean up out of the hole and stay clean the rest of the track is my vp limiting the fuel or is my lines injectors etc. limiting the fuel seems like I'm pushing plenty of air for the setup currently and would like to squeeze out anything possible IF possible. Just currently picked up locally a set of .093 connecting tubes set of .093 vp44 lines and a set of 6x.018 injectors all industrial injection products ....... My question is changing the injectors or lines to a little bigger am I going to see any changes........ Looking for guys that have possibly ran bigger lines with possible stock vp..... I've been told not to run them that you make more power with stock lines and the truck doesn't like to idle with the bigger lines and you need a bigger vp pump to feed the bugger lines..".....I've read more things that say don't run them over people saying to run them , anyone got personal experience with anything similar and care to share there experience /pros vs cons
On the injectors I've been told I'm running too big of an injector as is right now for a stock vp and that a 6x.018 won't help anything .....anyone tried or had good luck with a bigger setup like this with the limitation of a stock vp? Again pros vs cons
Any expert vp guys out there can explain what the vp 44 is doing IF it truly does have a cracked diaphragm...... I have hard to start issues more so when the truck I'd hot or been ran hard he se the reason I think I have a cracked diaphragm is this returning fuel that normally would be being pushed to the injectors through the crack? In other words am I loosing power/fuel to the injectors because of the cracked diaphragm?
