quick question.

do the under injector noszles or whatever system (i know there are several diff manufacturers now) affect your daily driver tune?
from looking at these it looks like they stand the base of the injector up from its seat.

does this affect the injector spray patterns?
normal driving habits?
tune?
any issues to be concerned with?

thanks.

 

if the fuel injectors are not lined up perfect then yes. the fuel hits the walls, and drips. if you aline it correct. your good

 

What Noyzee said. We carry the NX style and the Cold Fusion style. These kits can be a very trick/inexspensive way to add DP without drilling up your intake.

thanks guys.

im working on a v6 fbody.
it has upper and lower intake manifolds.
i attempted installing a "regular" direct port setup, but because of the way the mani's come together, thier mounting points, and the limited space due to other engine components i had min room/space available.
i thought i had it figured out (after my 3rd set of intaked mani's, thier cheap), it cracked while tightening up the upper intake to the lower..

i found 4 of the NOS styles, but during mock up it seems like the injectors might have issues with flowing thru the noszle.
shooting or brushing the injector spray on the inside of the noszle concerns me, hence the reason i posted the question.

the quest hasnt stopped, just on pause until i can feel that the DD aspect wont be affected.
peace,
dan

 

So is drilling the intake and lining everything up tough??I have a 96 t/a that im getting ready to drill direct ports and we were wondering about fuel dripping of the nozzles....how do you if they are right without starting the car??
