you wanna know how to do it????
Heres what I did....I was racing my dad in his 01 Cobra....on the track. This was a long track. We started the race at 80mph...I started in 2nd, and immediately hit the N2O...I kept it on for at least 20 seconds....and then off, and then on a bit more, and then off, and then...you get the idea...we kept racing for a good ways, when all of a sudden, my car wouldn't go past 140mph anymore?????I was like what the heck?
Slowed down, gave it gas without the nitrous, and the car was sputtering really badly.
Drove it home, pulled the plugs, and cylinder numbers 1, 4, 5, and 8, the plugs in those cylinders, the ends were melted....even the porcelain.
So, I change plugs, start the car....still runs like crap. Do a compression test and lost compression in all 4 of those cylinders.
Long story not so short, when I pulled the heads, looked at the pistons, they were fine...perfect...finally checked the valves on the heads, those same cylinders were not sealing(the valves)....
So, after all the hell and abuse I put my 4.6l through, all it needed(before I swapped the 351W), would of been a valve job...if I knew what I know now, I probably would not have done the swap.
So theres kinda a way to kill the motor(which I really didn't)...
