Steel pipes

[rumrunner]

Is there a reason that steel pipes aren't used on nitro motors ?

Thanks Shane

Weight.

 

[rumrunner]

Is that it weight ,wouldn't steel hold heat better aluminum

Maybe in the USA ... in Europe Dave Marles exhausts are steel ones.

(and yes .. he has alu too .. but the steel ones are commonly used)

do the steel work better?

Dave Marles = Awesome

As the (super) silenced nitro-pipes will clog during use .. you need to thoroughly clean it once in a while.

The stuff that gets that done .. will eat your aluminiumpipe in just a few hours (also handy becomming anodizing off)

 

The stuff used is potassium hydroxide (MSDS Number: P5887) into a high glass flower-vase , and left overnight.

Next morning put on chem-gloves , and flip it .. cleaning the other end.

In the evening ...put on chem-gloves ... and rinse in the shower (wife out of the door is needed ... ha ha )

 

New Hammerite BBQ-paint on it .. and you're good to go.

steel resonates better then aluminum.

I was wondering the same thing , I have never seen a steel pipe on a nitro outboard

 

[rumrunner]

I was thinking about using a redline gas outboard pipe on a cmb 101

 

[BigChuck]

Shane............There are Plus an minus to using a steel pipe on a 101. Enjoy testing.

BUt keep the Alu pipe close by, you will be surprised at the results.

Yes I have tested it in 04/05

 

[julianconde]

i would not want to test a 101 with steel pipes that's just me B)

My experiences;

A friend and I back-to-back tested a steel pipe vs carbon pipe of exactly the same dimensions back in the 90's on a 21 engine (Audio Resonance difference between steel and carbon = huge) We tested it on the bench with a Kavan prop chart, a scale off the side of the mount for crude torque measurement and a handheld tacho for rpm - saw practically zero difference. Not an accurate "dyno" by any menas but it's what we had to play with. Next we tried it in a boat - no difference. My friend did the same test in a different boat with different engine for the same result.

My 1.03 / 16,99cc (Evo-100 P/L in RS) runs perfectly on a PMB-CS5 steel pipe.

The main reason is that there are lots of aluminum pipes and very few steel ones. Aluminum is much easier to spin than steel, so steel pipes are usually welded from rolled rings. That's a lot more expensive process. Steel works well for one off pipes.

tested few identical billet steel and billet aluminum pipes on .21

Wall thickness steel .025 and .015

Wall thickness aluminum .030 and .020

aluminum wins

 

[rumrunner]

thanks everbody for the help ,the reason for this ? is nobody makes a big aluminum outboard pipe ,but there is a big steel outboard pipe.

[julianconde]

if you give some measurements of what you need maybe mark hopper can custom make you one just a thought

if you're talking about the gas outboard pipes... Hanson offers an aluminum sidebleed pipe setup.
