Pipe / Header Sleeve over fix

[Tom Foley]

Well... got tired of the coupler wear deal and even the Teflon ones over time develop bulges and slide off etc . so i started making Billet pipe extensions welded on to the pipe that sleeve over the header snd accept the 7/8 " X large silicone over top of them that is not exposed to exhaust gas temps . Testing went well and this is available as a service now for 35.00 per pipe . Check it out .

Great idea. . Great looking work.

Made something like that on my Sport 40 which would burn a coupler ever couple of runs. The only other thing I did was made it water cooled. seem to help and not effect performance. I will look for pictures and post,sold the boat so not sure I still have pictures.Jerry

Nice work Tom, on thoseare you able to move the pipe in or out? I know Dan McCormick made a couple few years back he was able to move the pipe. I check it out up close in couple weeks might be good to try on the sport40.

They will not burn couplers , they overlap near an inch . The couplers on my AB pipes on the Mac headers last over a year .

Tom;

Are you willing to do smaller pipes also, IE: 21 pipes

 

[john v]

hey tom

how about hooking up a servo to the pipe and having an inflight pipe length on a 3rd channel

 

[TimothyJones]

It looks very nice Tom, very clean look.

Tom where did you get the pipe pressure taps , do you sell them .

 

[HendricX]

Teflon-coupler with very-tight press-fit and 2 springclamps will do the job too.

Yes , any size .

Yes , nice deal there . Had those eventually loosen up and get mishapen after time but everything has some maintenance associated with it .

That's why I wrote "very tight pressfit"

Wall-thickness is 3mm or 1/8"

Teflon inner-diameter 1 > 1,5mm or 3/64 > 1/16" smaller as pipe-header and /or manifold outside-diameter.

Use heatgun to soften the teflon-coupler , and use the continuous pressure provided by the spring-type clamps.

(as the teflon-coupler will soften during running .... the spring-type clamps will lock that up.)

It will hold several years on glow-engines , and 2 > 3 years on gas-engines.
