mac 2.5/.12 pipe length?

[ClayGlover]

to save time, im hoping someone can give me a pipe length to start with (plug to pipe's max diameter thru center of pipe). it's a rear exhaust mugen/nr .12 with an associated header and a mac #1110 2.5 pipe. maybe i'll get lucky and get a suggestion

With that pipe on my NR, I am running it at 8-1/2". It runs kind of sluggish until it gets on the pipe, then hang onto your hat! I set up my RE Fantom .12 with the length but haven't had it on the water enough to get it up to speed.

ron,

i appreciate the info. in your above description, what prop was that you were running, the V937 / 3?

just so i hopefully can get close with one pipe mount hole in the hull, that 8 1/2" measurement is from the center of the cylinder thru the center of pipe to the rearmost of the widest point of the pipes belly? lol, no weld line makes it a lil tricky. thanks for your help

 

[Ron Olson]

As a matter of fact, yes, I did have the V937/3 on it at the time and that's where I took the measurement at. If you place your pipe mount on the stinger, it can give you a little flexibility for your length. You might want to go maybe 1/4" shorter to get it on the pipe quicker. I like this length because I like hearing it come on the pipe, a sound that I don't get with my other boats. It's like cruising along then sticking your foot ot the floor of a 4 barrel carb.

Hey Ron,

In looking at the trinity engines at Tower Hobbies, which Novarossi are you running?

Don

 

[Ron Olson]

The side standard exhaust, rotary carb, non-pull start version. Part # TP095.

If I can get my boat running good with the OS TR, I sure would like to try this one. The specs look great but most of all I just like the looks! 8) The description says threaded but the picture shows SG crank. My biggest problem with this engine is how to get it past the wife! ;D

 

[Ron Olson]

I used to get a lot of stuff delivered to work. I worked in shipping so I was always there when the Big Brown showed up. Now that I'm on 3-11 and the wife is on Days, it's a lot easier to get things delivered at home. Going back to 7-3 in another week.
