H2o cooled pipe

[water dog]

I am using a cen composite pipe and it is getting so hot that it is melting a little .Is there a chance I can hook up a waer line and cool it with water.Maybe I can run my engine cooling line from the head to the pipe and out the back .I dont want the water going into the tank pressure line .This is a nitro setup.

I thought you were running a macs pipe. A pic would help. Most of the time people say not to water cool the pipe because it is surposed to get hot and that does something for performance. Also there is the chance of water getting into the pressure line.

I had the macs pipe on but I think the cen pipe worked out better ,but I think that I may need to shorten the macs pipe a little more .The macs pipe is thinner so I would think it would let the engine wind out more , than give more power.I dont need more power ,I want more top end .I could probably go with a differant prop but I dont know much about props .

The macs pipe will give more top end the more you cut it down. The longer the pipe the more torque, the shorter the pipe the more top end and rmps. What prop are you running now??? Ask steve what to use at offshoreelectrics.com

I am running a carbon fiber 40mm upgrade prop .Its not bad but I think I can go alot bigger.
