NOS Sniper system for a m104 engine

If you got a 6 cylinder,and you want to out run V8s,a NOS Sniper universal system is a cheaper way of doing it.
This Kit is perfect. Remember use button after 3000 rpms to 6000,then let shift,or ASR will mess you up.

Hey! Have you tried to dyno it to see how much torque would it make!?
Also, did you tune it in any way to have a good mix of NO and fuel or someone did it for you!?
I'm thinking of doing it to my m120 (M104 x 2) and I think that would be more appropriate that supercharging/tubocharging and their multiple thousands investement.
I wonder how the internals are coping with the extra power!
I think a 2 x 75 shots would be enough for me to get it from 400hp upto 550 hp
Mb_Fahrer I'm surprised you didn't tried it yet on one of your 600s or 73s!

hey Mich,a M120 running NOS would be awesome.As far as my internals they are good to 500hp.Serveral forced induction M104s running in that range.
I can't get a tune with a HFM engine.I'm running a little rich,better to be rich,than lean.
Your engine will be fine with a 150 shot.That should burn off the tires.remember don't spray until you reach 3,000 rpms.

yea I see! the thing that still annoys me is not being able de deliver the N2O before a certain RPM (3000-6000) to spare the engine/tranny I guess these beast need to get moving from 1800 rpm and that's what I love about supercharged 55s engines. I'm thinking maybe 2 nitrous injection tips, one 50-75 shot as of 1800 rpm and another that kicks after 3000 and that adds another 50-75. As I can spend all day under 1800 rpm unless I'm pressed that way one could have tangible down to earth performance at low rpm starting from 1800, not only when racing above 3000 rpm which I rarely do.. matter of fact i don't recall redlining me engine more than once yet.
Well actually there are gradual delivery systems that already exist but I guess they would cost more that to double the spraying parts

I was wrong it 2000 with full throttle.Unless you purchase electronics,then you can appile at 3/4 throttle
Yes I spray from 2 grand to 6400,then let trans shift,then spray again

Are you running Dry or wet ?
Man if you're running 150 with no problem on one 6 cyl bank then on 2 banks that makes for 300 extra hp.. miammm
then with a 75% efficiency, that makes for arround 225 hp net increase.. So we're talking 625 hp !
Ohhh can't wait for a few days off.......
