Contour Enthusiasts Group Archives Forums Modifications Forced Induction direct port possibilities.....

wow man. i saw half that movie. it was horrible BTW.

and yeah, do this. hold your main feed line in your hand. open the bottle wide open. its pretty hard to hold still. 1000 PSI. it does make a diff. direct port gains are minimal but its still a gain. the main reason for me to do it is to run more nitrous than is recommended and further reduce the chance of puddling in the UIM. i'm going with the plates, because i dont have to ruin my UIM or LIM to do it. thanks for the input guys! i'll have pics as soon as csvt49 helps me build these things!

I see what you are both saying, but Stazi is right about blowing te nozzle...no way,..

if your one single fogger will withhold the 100psi...then 6 spread out and screwed into the manifold should be plenty...

But it would be less risk of puddling. It would be something new nonetheless.

actually the nozzle fits into a steel threaded 2 piece bolt that bolts on each side of the intake so it cant blow off. im just worried about soft aluminum threads. we'll see how it goes, when i try to mock up a set of LIM's

This is the only direct port picture I've ever seen on a CSVT. I have no idea the details behind the picture. IMO, this is the 'best' and 'easiest' way to go.

its not bad. its the easiest, for sure. but its not the best. you still have to pass through about 8" of intake manifold (very hot, aluminum intake manifold) my setup may put down a whole 10 HP more than that setup with teh same jets in it, but it will also be very clean considering i will have the black coated race lines on it and all the nozzles will be under the UIM so the only thing to be seen by the untrained eye is nitrous solenoids. which i will probably leave out in the open for looks oh and big red and blue anodized "shower head" distribution blocks haha


EDIT: maybe not 8" of intake manifold.... at a second glance. the only thing that sucks is (correct me if im wrong im real tired right now) he has the nozzles in the secondary runners correct? so it can puddle right up if he hits the nos before the secondaries open, or if the IMRC fails it'll puddle too.

I can't remember which is which. But wouldn't puddling not be an issue, if he weren't spraying until his secondaries were open? (Which is pretty much just for a second or two in 1st gear during a drag)

The short runners are the secondaries. Long tubes help low-rpm, remember?

With a window switch it's a non-issue.

thats what i would do probably. i was also thinking about making vacum secondaries from this SE that i saw in the scrapyard wheni was looking for used boxes. either way, i could just tap into the long runners too that works just the same
