System putting out way more than it should?
System putting out way more than it should? I've got a car with a nx plate system on a victor jr intake. With 41N 22F @ 1050psi N and 59psi F the car put down an extra 150 rwhp. On a 52N 35F at same pressure it is putting out 260 rwhp. Each solinoid goes through 2 jets into the plate so the jets are supposed to be for a 100, 150 shots respectively. This is with a 10 pound nos bottle, 6an feed line, and the bigger NX solinoids. The a/f for the first 100 shot pills was 11.7, and the 150 pills were 10.2 a/f. Any thoughts on why using these jets is giving way higher dyno output?

Sorry... had my jetss wrong on 100 hp shot. I edited it. We did have 41N 22F on the first one which gave 11.7 afr. We then jetted up to 52N 28F and went super lean 18-1 so backed out of it and changed the fuel jet to 35. Found out that one of the fuel jets had a small piece of rubber blocking it after running the 35 which netted a 10.1-2 afr. We ran out of time to play with the jets anymore, but with a 28F it probably would have netted a 270 gain at around 11.7-9 afr.
The exhaust is a 3" dual with an x all the way out the back with mufflers. Heads are a wcch 215cc edelbrock cnc. Cam is about the same as a trex, but not big for the motor.

I think most of it has to do with the elbow. People with the smashed down elbow run no better than an ls6, but put on a decent elbow and the gains come in. Also running a vacuum pump to help with ring seal. No porting was done to the intake. The plate is nx's newest design for these intakes. Sorry for the bad pics, but haven't got a chance to take any more with my better camera.
