Default NOS tubo spooling system

Has anyone else heard about these turbo spooling systems that use a small shot at low RPM to spool up the turbo faster? Are they actually effective in cars with noticable turbo lag or is it just a load of BS. Normally I wouldn't use a fogger to save my life but in this limited role I might give it a try, say on a Baja Turbo. Thanks

yeah, there are systems out there like you described. They break down into 2 basic groups, the cheap and scary and the expensive and good.

The cheap scary kind are basically a standard nitrous kit with a boost activated swith that cuts the nitrous at a specified boost limit. The problem with this is that at some point you are running a very large nitrous hit and alot of boost at the same time. Which on very stout motors isn't a problem, but if your motor can handle that, then why not just run the full n20 hit all the time? and ABSOLUTELY avoid these kits like the plague if you are using a RRFPR as most of them use a fuel return clamp to increase fueling. The power delivery on these systems is also pretty violent and wierd.

The good kind use a variable nitrous delivery system to phase out the nitrous as the turbo spools, most of these systems work very well and have a really nice power delivery and they modify injector pulsewidth for the extra fueling. Some higher end standalone systems also offer this type of functionality.

In the end... if you are running a turbo so big your motor won't spool it properly you might want to get out of the 4 cylinder world unless you have LOTS of money and an engineering degree

ESX, and DSS-racing make such applications...
ESX 9 sec. WRX with NOS/turbo, one time they forgot to pre-fog, and it ran 12s... , heard they were using the 100 shot application

DSS, 1g DSM block made 9s on a turbo application, while with NOS it hit 8s.

I would imagine they were using turbos as big as TD10 or T-76 Garrett or something, but the turbos were custom made so its secret.
