i have had both nx and tnt, i have the tnt now, and really like it. its a little hard to try to mae the ring/lid/maf all fit toether nice. but the quality is really good.

as for the nx, i really like it too, made real good power and simple to install. my buddy has a nx kit on his car and it looks real clean when you do a little custom work on mounting the noids and mounting the shark nozzel.


like was said earlier, dont run a 150 shot without a pump, and i dot even think i would run it with a pump on a stock block for long. i broke 2 pistons running the 150 shot on my stock motor and i never even sprayed my car that much.


good luck

I am using stock fuel pump still, at idle I have 70 psi.!
The lowest fuel pressure I have seen on 150 shot was 61 psi. !

with the pump under load on a normal
wiring harness? If the pump pressure
dropout is due to electrical system, that's
a cheap fix... Something worth looking at
during a dyno run, the voltage across the
pump, and maybe the drop across the relay too.

 

I went with NX because I got the kit very cheap, they are very good quality, and you get a lifetime warranty on the solenoids. How can you beat that? I figure if you use the same size jets, you will get the same amount of power no matter what kit you use. Just my opinion.

<strong> Here is the jet pattern for the LT1cars in comparison to an NX system. This is taking into account that TNT uses two jets and calculating the effective orifice surface area of the two jets for an equal comparison.

100hp
TNT 55.1 Nitrous / 25.4 Fuel
NX 52.0 Nitrous / 31.0 Fuel

150hp
TNT 65.0 Nitrous / 35.3 Fuel
NX 62.0 Nitrous / 35.0 Fuel
