"nos" turbo spool up kit??????

[The_Baldman]

I've heard a little about nos brand making a spool up kit for turbo cars. Anyone know how this works? Does it change compression or does the nos enter into the ex maifold? It sounds like a great idea. I've got a 97 gst spyder that is an auto. If I could spool up faster...well, 5 speeds would be in big trouble. I already jump a car length when 5 speeds shift. I am getting a 2800 billet stahl to add to my fully built auto tranny with translab shift kit. This should be fun. Any input will be greatly appreciated.

Get one of their wet kits and spray like 75 to it. Get a transbrake too

Nitrous is always injected before the throttle body, or in direct-port systems, straight into the ports on the intake. It would not do any good to inject it at the exhaust, then you would just blow it out the tailpipe with no perfromance gain whatsoever... There has been discussion about running a small shot at low RPM using a window switch to deal with turbo lag... With your car, if you're drag racing, can't you simply stall up your convertor against the brake when you are staged, and then launch under boost anyway? That's basically what I do with my 5 speed. I will use the right foot heel-toe method on the brake and the throttle and feather the clutch with my left foot and this gets the RPM's up and spools the turbo. Its not very nice to the stock clutch, however Then I can launch under boost and feather the clutch to try to minimize wheelspin (which there is alot of, my GS-t is relatively stock) I can whup my buddy's auto Talon turbo every time... but he doesn't know how to launch. If you're pulling a car length on a 5-speed car every time the guy shifts, then I would say the driver doesn't know how to power-shift his car. I wonder if you could beat a 5 speed (assuming everything else on our cars was the same) piloted by by a driver who knew what he was doing? Whatever the outcome, it would be a fun race, too bad you're not near me!

Nitrous oxide kit + pressure switch = Turbo spool up "kit"

Basically you wire in a pressure switch to turn off the nitrous above a certain boost level. So let's say you need to get up to about 15psi, then you'll be able to WOT launch with the nitrous and once it hits 15psi, it'll cut off and the turbo should be spooling nicely by then.

But since you have an auto (and I'm assuming stock T25 turbo), I wouldn't suggest running nitrous to "spool" that little guy up. The key to a quick launch with ATX is a higher stall torque converter and stronger end clutches. Not only will it flash up to a higher rpm, but each shift would be more crisp. My brother's 97 GSX auto builds about 15psi on the launch. It'll actually chirp all 4 tires on a nice cold turbo friendly day.

Get a transbrake too

A brake is an expensive option if they are even made for our cars. You need a new valve body that is only a manual valve body and a special converter plus the solenoid. A bit pricey and probably not a good idea on a FWD car, unless he has a good tire and suspension setup.

If your going too spool up your turbo with nitrous there is absolutly no point to turning it off after 4000rpm or something stupid like that. If your going to spray, then spray right though the entire RPM band and pick up the HP. Trying to use a spray kit to spool the turbo up then turning it off once it spools is retarded. If you don't believe me do it on a dyno and look at your plot and tell me what looks wrong.
