Look I m not trying to be a butt LOL,its just that nitrous is dangerous,especially f used wrong.Now stanglover,read my post again I was giving the nitrous car an avantage with 250 RWHP just to be nice,but it still did not compare to the KB in PEAK power.But I know how nitrous power curves are,in that your peak power is USUALLY at whatever RPM you first spray it at,so if you have traction and spray it off the line,you will have some crazy times.Now mustangman,yes if you put only a 100 shot then yea it will last a little while,but look a 100K engine is already worn and has lost a lot of compression,so in a way its a little easier on it,but the egine is also weaker.Now joel this isnt ricer math,it is just facts.The only ricey posts are from you,when just like a ricer you starded digging up past posts on DIFFERENT subjects cuz you didnt have anything else on me.AND also there is really no false information there,just I am pretty sre,not too shure,may do this,kind of posts so thats not false due to the fact that never set it in stone.Yea Gino I did dissregard things like raceweight because even right now the N20 guys are crying for more weight peneltys on SC cars because they want their ETs to be closer in BRs so we will not go there.Nitrous gets beat hands down in highend racing.Now about reliability,if your motors built for N20 it will last quite a while,but a stock engine is not designed for it,nor for SCs and both WILL cut engine life.In lower shots of 50-75,a stock motor will be almost unaffected and will last a long time,but when you start being a man and go past 100-150 then you stock engine is in danger,and besides like KIRKYg said,it is way easier to mess up with N20 and ruin your engine.All it takes is for the N20 solenoid to screw up,and your engine is SHOT.Personally I dont want to take that kinda of risk with a perfectly good motor.
