Nitrous Dyno Thread....
heres an old dual stage using two rpm window switches on my 385 iron block from a several years ago. It made a 715 rwhp and 720 tq on a later dyno but I dont have that one. It was dual stage dry

Here is one on a 408 with a dual stage Progressive dry/wet direct port as controlled by the FJO mini controller. Note the rpm when the run was ended. we were tuning at this point and it was too lean. Also note the HP the 408 made with the nitrous tune NA.
Here is the same car after tuning. There is no Tq or rpm because we couldnt get the pickup to read right through a run and it makes the RPM grapgh nearly unusable. So it must be put in MPH.
here is my old 415 ci motor and nitrous dyno. The nitrous was using the NX Maximizer in rpm mode from 0% ramping to 100%. It was a 200 shot direct port. Pretty damn smooth.

Now you see why I've been preaching the progressive controller. Makes your power curve look more like a turbo curve. Much easier on the engine and driveline when you don't shock it with 100% all at once. Nice graphs!

It's not half as impressive as the big boys. But this was a 350 dollar NX wet kit using standard 150 shot jets on a 2000 Corvette M6 with only a VaraRam. Everything else was exactly how GM built it.

Here's some video to go along with that dyno sheet for JeffT 
If I remember right, the specs on the cam were in the 224/230 range
Dyno + 1/8th - Dyno
1/4 - 5 dollar milk shake

Was it a direct port or a TNT ring. I didn`t think you could go bigger than a 200 shot and be safe? Let me know, Thanks!
