nitrous
 

I love this message board. I'm going to the track tonight and racing a '68 Camaro with a built 350 and 125 shot of nitrous. Just in case I needed a little extra boost, I too was looking into stepping up my 150shot to a 200. I called NOS (which is owned by Holley now) today and asked their tech. guys. They said the most you can go up to with that dry system is a 175hp shot. A size 37 flare jet goes in the vacuum T and a xize 73 flare jet goes in the nozzle at the throttle body. They mentioned having to have that shim in the nitrous regulator to boost the flow of nitrous into the motor. I already have that. But that part# 17933-S. Although P.A.W. & another speed shop near my house could not pull up that part#. Kind of strange since the NOS dry kit 5115 has been around for many years. Hope this helps some.
