When you are talking about a 200 shot, is that 200 horsepower to the wheels or at the crankshaft?

 

Usually it's supposed to be to the crank, but alot of the time I see people's dyno number's and it ends up being closer to the wheels than the crank. So to answer your question......umm......I dunno

 

It depends on the kit Nx is at the wheels most others are rated at the crank.(I think)

 

Moving to Nitrous tech...

its an "amount" of nitrous. a 200 shot will give a car with a nitrous cam a lot more power than a motor like mine with huge overlap and not too much exhuast favoring.

also, you reach the point of dimishing returns after a 150 shot or so (depending on motor) because the nitrous begins to displace the air.

a 150 shot will give you 150hp, a 200 shot will give you 175, a 250 shot will give you 200.

the correct way to "compare" is to compare the amount of nitrous you are spraying, not a "shot"

a 75shot for an Lt1 will blow a civic apart. a 150 shot on a civic wont even phase an LT1 (or maybe i have it backwards )

Can someone clairlfy this? I guess I don't know as much about N20 as i thougth....

 

im not sure wth he means so cant clarify.

basically they bare rated in HP gains,but there is no set way to see that gain. car setup's,weather,nitrous kits all vary the effective gains. it's a rough idea of how much more power the engine should be making.

 

a 75 shot is a set amount of nitrous (ie xcfm or however they measure it)

a 75 shot is a different physical amount of nitrous when comparing a 75 of a civic to a 75 shot of a 502 big block
that "75" shot in a LT1 will yeild different gains depending on heads and cam setup as well.

 

Okay, I htink I get it now. Thanks.

GO YANKS!

 

The horsepower rating is application specific, assuming the engine still has piston rings and is in good tune. If you really want a comparitive measurement, you should compare nitrous jet sizes to see how much nitrous is actually flowing to give the said gain.

NX rates their kits at the wheels, NOS rates their kits at the flywheel. Just remember that a kit rated at the wheels will be about 20% more at the flywheel (an NX 150 horsepower shot is equivelent to almost a 187.5 horsepower NOS horsepower shot).

 

how the hell do they rate at wheels?


i'm sure a big stall TH400 with a 9'' will be losing a butt load more than T-56 alum ds 10 bolt

 

straight of NX website...

Q. What is meant by 30, 50, 100, 150, and 200 shots?
A. "Shot" is commonly used slang in the nitrous community to refer to the amount of horsepower increase provided by the nitrous system.

 

I would imagine they rate them for 18-20% drivetrain loss which is what your average street strip car sees in drivetrain loss. I see your point tho, unless its application specific like for 98-02 LS1 Cars its awefully hard to promise rear wheel numbers with so many other factors influencing the numbers that have nothing to do with the nitrous.

 

i dont get why its rated by hp.

thats like saying i have 500hp heads

 

it's rated in HP becuase the amounts are controlled. they also have test mules and dyno the crap outta em for the hp gains. not all systems use the same exact jets.

there is no other real way to quantify the gains unless they use a HP number.

also most systems say they are "approximate" gains,so it isnt an exact gain,just in the general area.
