Pipe Talk.....

[Slideblues]

Yeah that goes back to the statement I made at the first of the post of the tempering of a aluminum pipe while running it, the older the pipe the faster it was.

Gene ;D

Gene,

The Bolly pipes are reasonably thick walled too, which would help with stiffness. I wonder if there would be an improvement if I had them made with an extra layer or two of CF? ???

Ian.

 

[Slideblues]

Thats the magic question Buddy ;D What is the optimum stiffness for the best performance 8)

To me it would be worth try'n out,

Gene ;D

Gene ;D

Tempering of the alloy pipe will change every time it is heated / cooled. The cooling rate will determine the rate of temper / annealing. I mentioned on the listbot that the Crystalline structure of the metal will change depending on temper. It would be feasible that if in fact the temper is what causes the good pipe to work better - then this can be proven by looking at the structure under a microscope.

Qoute " My oldest pipe ran the best"

Why would you keep a pipe if it didn't work? ;D

Ceramic coating the inside made it perform better, could it be a more optimal size concidering most pipes are made for overall performance on a varity of timed engines?

 

[Ian Inverarity]

Tim,

I have seen OPS pipes that anneal after a bit of running, they become so soft they almost bend under their own weight!!

Gene,

The pipes are so light that a few extra layers of CF would probably only make them as heavy as an alloy pipe 8)

Mike,

I think the ceramic coat effect would be a thermal one, unless the coating is thick then the volume change will be minute! :

Ian.

 

[Slideblues]

Tim that would be one way to compair it for sure

Mikie G. Exactlly!!! ;D

The coating would be thin, dont know how thin?

Ian, yeah that one of the great things bout CF it SOOOO lite

Gene ;D

 

[Mike G]

Thin pipes RPM, fat pipes torque?

Now if they could just make a resin that will hold up to Gas temps.

I got some SS pipes coming, it will be interesting to see how they compare to the Alloy and steel pipes I already have.

 

[TimD]

Thin pipes RPM, fat pipes torque?

Mike, not always! The difference is width usually come back to cone angles which effects the pipe. The slimmer pipes are less kind when you run "over the top" of the band.

 

[Roy_Munoz]

Gene I couldn't tell you the cost of doing the coating,because we got all of our pipes coated for Free...But I understand that it's not cheep..It best if you sent it in a large lot,and split the cost...Like I said it was an expirement,for them as well as us...

 

[Anders_Martinelle]

Mike, i would say...

Slim pipes: wide range or power band.

Fat pipes: narrow range or power band.

I think it`s easier to get a boat going with a little smaller or "less cone angle" by my own experiance.

BUT big pipes generates big power if you can get it to run properly.

Hi Guy's

I always thought short and fat - wide power band

long and thin - specific power band.

related to cone angles and RPM expected.

GT ???

 

[Anders_Martinelle]

RPM range is mainly distance+ in some point volume.

AS you know you can have 3-4 different pipes that you have tested and all have been with different length but you run the same speed and rpm....

I can bet that you will have 10 opinions from 10 guys when it comes to pipes!!

It`s very difficult to get the "optimum" setup with pipes beqause some engines like some pipes and vise versa.....

Here is some of the pipes i use for testing .

How will the CF pipes run w/higher % nitro?? I hear the talk from local guys that they don't like it?? Why??

 

[Slideblues]

I ran the poop outta my CF pipe with 60% and had no problems, I did hear that some of the early versions went soft.

But they changed the resin and solved the problem,

Gene ;D

[ClayGlover]

It does sound very interesting Roy, what would a .21 size pipe cost to have coated?

i read somewhere recently that it runs US$20-25 for jet hot coating per pipe.

ah, here is the thread. a gent named Joe Hill (rings a bell?) does jet hot, and there's another guy that does Airborn aluma coating, which is apparently the same stuff. here's the link from jim's-

aw, that didn't work. click here and go to the 2nd page of the "CC racing engines steel tuned pipes" thread.

I agree - my own opinions on pipes changed with my latest engine (K67)

The pipe I thought shouldn't work very well turns out to be the best None of the other pipe's I had tested came close to it. It sure likes fuel with this pipe, but is making a lot more rev's and power and I can live with that!

 

[Slideblues]

Yeah I agree, When everyone raves about a certain pipe I wait till there is info about a few setups before spending money.

At best the manufactures have to hit a happy medium, then its up to

setup, timing, mods, and dial ins.

Gene ;D

Gene,

That's a wicked looking pipe?? What would one of those cost me??
