yes i know what u guys are on about, and i fully agree with you.

And i didnt say u would see a massive drop in engine life, i said it will slightly shorten it, im meaning like a litre or 2 nothin to worry about.

Yes changing up to 30% is a much wiser decision than spending 200 US on a dodgy little nos system that lasts 8 seconds, i prefer to run 30 in my engines because of the added excitment, balistic accel and faster top end, if that means losing a few litres then so be it, i had more fun than i would of with nitrous or less nitro.

Nitrous does work, but for what, that short ammmount of time, its stupid, go buy yourself a Nova engine or a nice 12 or 18 TZ and u will have more fun than u ever would with a little bottle of nos
