Does anyone have a recommendation on who makes the best Dual Stage Wet Nitrous kit? (Cold Fusion, NOS, Nitrous Express, ZEX, etc...)

What's the optimal sized kit as well for a C55? 75-125hp, 100-300hp.

I am leaning towards the ZEX dual stage at this point.

Ive run the NX kit on a few of my old cars...IMO a 100 wet shot is plenty on a stock C55

I think 100 shot might be pushing it. I had a hard time tuning it for a 50 shot. Maybe a 75 shot is as much as I would go on this engine.

While most manufacturers can assemble a kit to work for you, please spend some time/$$$ making it safe with electronics.

A progressive controller like the NX Maximizer or Jacobs Nitrous Mastermind will help tremendously with delivery.

A wideband tied in to the system to cut nitrous on lean-out is a good idea too.

J&S safeguard will do the job for knock.

If you're not adjusting timing retard for the spray, you'll need an extra fuel cell/pump to run race gas for the fuel enrichment on the bottle.

Good luck. Post pics.

Well I am NO expert and NOT even a novice but AMG-Jerry has a 30 shot I doubt its a double type kit...I was told about a year ago that a 30 shot going into a S/C is like a 100 shot...I say this cause you do have a S/C in your car...do as ChicagoX stated do a decent amount of research...

The C55 isnt supercharged, so it'll be a little different...you are correct though about N20 and forced induction cars...it does give you more for less...I havent done any setups, so have no experience, just experience with the kits themselves.

The OP has a kleeman S/C on his C55...that's why I said it.
