Hi guys. Went to the dyno today to tune my setup - had a little problem. For those curious, numbers are in the sig.

Problem 1: On my second run my NOS Super Pro shot nitrous noid stuck open after I shut down - did a great job or freezing my entire intake tract. Luckily no damage was done since most of it sprayed out the air filter lol.

Should I try to rebuild this noid (since it's supposedly a good one - rated to ~400 rwhp) or throw it out and go with an NX noid?

Problem 2: Right after the initial nitrous hit, I get a 50 rwtq dip which quickly disappears and the TQ curve returns to normal within 400 rpm. This happened on both runs. Could this be another Nitrous Noid problem, or maybe a NOS remote opener issue?

 

i've never talked to anyone yet who didn't have to throw out their NOS brand solenoids. scrap them and go with something else.

 

You could sell it on ebay because people by used ones and sell them after they rebuilt them all the time.

 

did you check and see that there wasn't a tiny piece of crap stuck in it? That has happened to me before. Just clean it out and it worked fine...do you have a clean filter on the kit??? Shouldn't need rebuilding until it gets lots of use.
