6speed & big single (75mm) best way to spray no2 for spooling

TRUBBS

Can You Keep Up?
im planning on running a s475 as a single on my truck with my 6 speed. im thinking tell i get my bigger injectors im going to need to spray it a little to keep on top of the charger when i launch and shift down the track. what would be the best way to hook the no2 up to do so?
 
You should not need it on the launch with a manual trans. So just rev it up and launch, then activate nitrous.
 
i used a toggle switch and would flip it when letting the clutch out.. but that was 3rd gear hi launching at mud bogs..

agreed, hands were typing faster then my brain was thinking, i know with the stroker i could side foot it in 3rd and leave the line at about 10pounds but that was just with a 38r.

i thought it was bad to have the no2 spraying DURING the shifts?
 
i used it at the track with my 5sp for a few years a long time ago but only a smallish 100hp shot and i never had a problem shifting through gears then running a 14.2 or so

what mods was you running? might be a silly question but for spooling do you tap into pre-turbo,hot or cold side?
 
Kind of an old thread but been thinking about it myself. Is there a way to hook up a WOT switch with a progressive controlled? U let off it stops for the shift, then back in it at a certain lower percentage to help spool it but not make things go boom with a low boost level?
 
i went into the hot side. i used to make a bit more power than at the time a guy (nowel thomas) that would use a bit bigger jet on the cold side.. anyway i would rev it to about 28-3000 and flip the switch and let the clutch out at the same time.. back then i was only making about 425hp and would not turn it off until the end.. anyway that worked fine and it was about 14 years ago..
