trapping mid 120's help

So am going to start looking into my Nitrouse system to reach my goals. Am hoping N/A she will be around 118ish. Engine specs in sig.


How big of a shot will i need? What systems do you guys recommend? I will be shooting it in second not out of the hole, i need to be easy with the rear untill the new one goes in

thats what i think lol
i dont have too much experience with nitrous. i ran about 2 or 3 weeks with my nitrous motor on a 500 ish shot on a WOT switch and ran a 10.3X n/a and 8.9X with the shot.

Re: trapping mid 120's help

with your setup now I can see you trapping around 115-120. To get into the mid 120's, a 75-100 shot would do just fine

Re: trapping mid 120's help

I don't know why this is that hard a question, making some guesses, a 3500 car will need around 450 hp to go 118, and 540hp to go 125. In most cases when you're talking about numbers like that you're talking about NA powerbands, where you only have all the power at the peak. N2O gives you all the power at any point that you spray, so you can usually do it with a little less power then you expect, so I'd say that you'll need around 75-85hp worth of spray to do it.

Re: trapping mid 120's help

My 383 went 118-119 on a good day. 150 rated hit I went 128 full bottle. 4th or 5th shot on that bottle with the pressure alittle lower than I wanted, 126.xx.

Some respond better to the hit than others. 125-150 shot is all you will need and likely exceed 125mph.

its common for 11-12 second cars to pickup 10mph on a 150 shot. Some pick up as much as 15 but most I see tend to be 10-12mph or about that. Faster cars wont pick up as much. Slower cars may pick up more.
