Nitrous Dyno Results

[95zsean]

Went to the dyno(Mustange) yesterday and straped the car down and did a NA run and made 333 RWHP, not bad for corrected numbers. So I heated the bottle up turned it on and got ready to give it a 100 shot. When it hit 3000RPM the car fell on its face and the opperator waved for me to stop... Hole in the nitrous line from the solenoid to the nozzle. Found another line at a local speed shop and tryed it again. This time it worked, I made 422RWHP and 498RWT, I was verry happy and the dyno opperator was supprised. I made that with 5 Deg of retard so we tryed it with 4 and it made 5 HP more but the plugs showed too much time so on the street im go to pull 5 to be safe.
It was a shit load of work to install and test everything, but when you hit it what a feeling.....:D

Thats pretty good results. Did he have a wideband sensor in your pipe? If so what was the afr and what are the jet sizes you used on the 100 shot?

[95zsean]

A/F was at the tail pipe and it was an average 11.9 and the jets where 52 N 30 F.

i bet thats a fun car to drive on the street for sure,,when you say corrected numbers what exactly does that mean,i know nothing about dynos but i kinda thought with your mods in sig that it would be more than 333hp?your sig says 371hp?can you clear this up for a dumbass like myself?

by the way im most definatly not bad mouthing your numbers just wanting to understand more

No problem, the Mustang Dyno numbers are lower than any other Dyno because it take into account elevation, aerodynamics of the car and weight. Mustang Dynos are sometimes called the "heart break dynos" because they show true HP#. The # in my sig are from one of the other Dynos so they are high. Sooo if I wanted to have fun I could add 90 RWHP to my sig numbers and say my car makes 461RWHP LOL !!! :devil:

But the # I posted are true HP # and it's the best way to compare car's around the world.

Oh and the car is a blast to drive, it spins when it hits in 1st and a little in 2nd, and thats with 315/35/17 Nitto 555R drag radials on the back!!!

That seems about right. I normally think a 55 nitrous jet can make 100rwhp. I tend to think a .063n is needed for a 150 shot. But jet sizes by them self do not show the actual flow. My digital scale and timer do. :face_shocked:

Also the actual RWHP can be changed by placement of the nozzle further than 4" from TB opening can change a 150 shot to say 130 etc. NOT EXACT #s but you can get my drift...

The jet sizing is from NX for a shark nozzle and lightening solenoids. Their jets for 150 shot is 62N 38F, I'm sure you method is more accurate.

I was told or read that the futher away from the TB you can get the nozzle the better mixture and the more even the distribution will be. This is where mine is.

Thanks. I think its the heads being able to flow more than the cam can provide, but I'm not sure?
