How much nitrous can a stock 5.0 handle?

bill87 · 12-21-2009, 09:56 PM

I just purchased a 81 mustang coupe with a freshly built 306 and 5 speed. I don't plan on doing anything to the car except for suspension and a 5 lug swap/gears. I want to throw some nitrous at it but unsure how much it can handle before it would go boom!!! It will be kinda a weekend street/track car. So it wont be driven a lot. Whats the best shot for the block?

there are too many factors to tell for sure. But in stock form 200 seems to be the a good stopping point.

be sure to have a good tune and to back the timing out 1* fot every 25hp of nitrous you have on it.

I have a 200 on mine I've dont everything to 100-200. 150 is a good stoping point just don't ever jet up or you'll never want to go back lol. I did over 20 bottles through my stock motor with 188,000 mile befor i had to yank it and freshen it up and I'm still spraying 200 with zero issues. Just don't get greedy with the timing the extra ten horses from more timing just isn't worth it.

whats so bad running your car more advanced? i know it will eat a hole in the piston after a long period of time. but what other reason?

Nice to know what they hit in the 1/4 ball park with the 150 and 200 shot?(with drag radials)
