Question re: changing from SMC system to Razor system

[Rayk]

I'm removing my old SMC system and installing a new Razor system. I haven't removed the up pipe yet but would like to know if the hole I drilled in it for the SMC nozzle can also be used for the nozzle in the Razor system? Or, is the Razor nozzle a different diameter? :smile:

should be the same 3/8 hole as the nozzles are same type of mister nozzle though they might have different GPH rating
the thing to be aware of is you don't want the nozzle on the underside of the pipe which was common with the intank smc kits , with the razor it needs to be higher than the level in the reservoir which is the rad coolant tank filled to the top step (not the fill line)

I hadn't thought about that. So, there is a siphon effect if it's installed too low? Does it need to be installed close to the throttle body and on the side or the top of the up pipe? Any pics?

on the side , if single nozzle it goes on passengerside , about three inches in on the upipe allows for the hose coupler and makes getting a wrench to the nozzle easier

3 inches from the intercooler or, 3 inches from the throttle body? That location isn't too close to the turbo inlet?

maybe a pic is easier

Gracias, my friend. :smile:

Old Hole

You can take the pipe and weld the old hole shut at any welding shop for a few bucks. Instead of replacing the pipe.

Yes Paul is correct. I typically install above the turbo inlet/maf pipe. The distance doesnt matter as air velocity through the pipe is 150+ MPH at WOT. So a few inches back or forth is no biggie. Just a height issue to worry about to eliminate any chance of siphoning.

Thanks, Julio. Since the old hole will be in the back of the pipe, I think I'll take your suggestion and have it welded. Appreciate it. :smile:
