I keep hearing rumors that people have blown their motors on NOS, but I haven't seen any postings and have done searches. I am running a 55 shot and have had many people PM me worried about running it. I thought I'd ask to see if anyone really had or not. If by chance someone has, can you list the circumnstance?
There was a post in the drag racing forum about a svt focus blowing its engine with 75 shot of nitrous. The guy it the rev limiter, which is bad. I would be worried about putting nitrous on the svtf since of the dual stage intake manifold. I think it might poddle up easier.
If there's one thing that people won't be regularly admitting to, its that the reason their engine blew was because of them using nitrous. Especially since 99% of those people are probably getting the work done under warranty with a "uhh.. it just blew up on its own. I didn't do anything sir" excuse.
So are you guys saying that since the svt has different pistons (stronger right?) that they should handle nos a little better than regular zetec pistons? With in the next year I want to do a real small shot. I will be adding a JRSC, and with that would want to do like a 25-35 shot.
I just completed a NOS install lastnight currently running a 30 shot. I have a full review with install photos coming today but long story short.... I love it! I wanted to pass some jerk swerving on the highway in his fourrunner so I armed the system and before I knew it I was crossing 110mph.
Just went to the dyno and tried a 65 shot. Way to lean. Glad I had them check the air/fuel cause it didn't ping. Otherwise I would be posting that I had blown my motor! As far as pistons, they are cast aluminum and the rods are forged-steel.
