I have a question about jet sizes on a NX hidden system on a LT1. I went to the dyno and made 407 on motor and 639 on first stage. The jets was 70N 41F at40-42psi and 1000-1050 bottle pressure.This should only be a 150 shot ? Is there something wrong? Motor is 396,ported heads,10.1 compression nitrous cam stock intake 58mm tb. I love the kit just have ??? thanks

 

I have seen the same thing with different set ups. Different combos may yeild different results..(heads cam etc) That same set up on some other set ups we do makes the suggested hp.

I had the same result out of a NX plate for a Ford mustang. The car just really responded to the juice and on a 150 picked up 2 pluss hp.

If that is more than you are wanting just back the pill sizes down to the hp you are looking to achieve.


My Solid Roller LT1 picked up 222 HP and 335 foot pounds of torque on a 200 shot directport. Every now and then you will just run into a combo that really likes the juice.

I know its hard to swallow but it happens.

I don't see a problem. Better to make 52 more hp than to make 52 less. I had a kit one time make 40 hp less than it was suppose too but made right at 87 more tq than I had ever hoped for.

I agree with Dave.

 

ohh,
Its a Nitrous Outlet hidden system.. Not a NX Hidden system We just use NX solenoids.
