Anyone use nitrous to spool turbos off the line and how does it work or wouldt it be better to use it at the carb off the line till the boost comes in.
Never together but I have run each individually. I do know several guys that do it. You set it up in the exact same way as if you didn't have a turbo. Think of a lazy spooling turbo as a tight converter that doesn't want to get up on the brake if you are using it to spool. Same goes for going down the track which also yields a charge cooling effect. It all has to do with triggers, window switches, ramps, and delays. Your question was sort of vague, hence my vague answer. What specifically is the problem that you are having or are anticipating?
I have a TT blow thru setup , would you run it in to the turbos or in the turbo discharge tubes or under the carb , someone told me to run a fogger nozzle 6" befor the carb hat.If you are using it to spool and not to cool the charge, you'll want it as close to the runner as possible and I'd do it wet. Then I imagine you can kill the system with a hobs switch at X psi.
I did it. Foot brake turbo setup using a 100shot on a NX boost referenced controller. would spray until i reached 6psi and shut off. Total on time of the nitrous system was about 1 second per pass. 1.41 sixtys in a 4000lb truck this way.
worked very well for me. occasionally 1 would run the 100 hit the whole pass as well. truck picked up 8mph on a 100 hit the whole pass at 17lbs it went from 145mph to 153 on a 100shot.
