I was wondering if any of you have jethot on your turbos, Headers, or exhausts. I would go with the black High temp stuff. Do the whole system. Thoughts on this? I would be doing it for mostly for looks.



Thanks

excuse my ignorance...

Whats Jethot

 

It's a ceramic coating that keeps heat from being dissapated while traveling from motor to turbos. I would think that with the location of the turbos on the porsche it wouldnt do much for spool up time or anything because they are already right there. My turbo vette benfited greatly from the coating because the turbos are rear mounted and the motor is in the front of course.

There is a better company, slightly more expensive cant think of the name I'll look it up for ya.

 

Not a porsche, but on my 87 mazda RX-7 turbo I have had my turbo manifold and downpipe coated already.
Going to have the turbine housing coated as well when I get my hybrid turbo built.

Still haven't put it all together and ran it so can't give you any feedback.

here is a picture though

downpipe was coated in the wrong color and have had it recoated black, even though I'm about 75% positive that I'm going to scrap that downpipe and redo it w/ a different angle on the wastegate (added this and welded the internal wastegate shut) and run a far better wastegate reroute into the downpipe, further down the downpipe and far less of an angle instead of that 90.
That was my friends way of saving me money, before I went nuts on everything, ended up costing me more in the long run :-\
Oh well, that is life, and the cost of being picky.
Fix it once, Fix it twice, Fix it a third time. D'oh

The shop that coated these is www.turblown.net and they go w/ a coating company called polydyne, polydyne is supposed to be very good.

I have heard mixed reviews between the many different coating companies and polydyne seemed to be one that everyone was nothing but happy with.

My car is a turbo rotary, and if you know anything about rotaries they run higher EGTs than pretty much any other car.
This is supposed to be a high temp coating that holds up great on rotaries.
Downpipe is a gold color, manifold is a satin black.

The internals of the motor are coated by them as well.
Should be interesting to say the least, hopefully not tragic.

oh, and another thing
if you coat only the outside, that traps heat inside the material.
cast is very strong, but tubular steel sometimes can be damaged from extreme heat.

My coatings are both inside and outside.


Oh and just to throw this up. I'm having my intake manifolds and turbo inlet duct ceramic coated inside w/ a teflon like coating inside. Supposed to increase CFM airflow. And the ceramic to keep heatsoak to a minimum

 

VRalexander has it done too......

 

Had my headers sent out for the jet hot treatment, just got them back and on recently. It really is a great touch, it is somewhat of an attention grabber for me, people see the headers and take a second look at what might be under the hood. I would go for it definetely....

I have done several sets of headers and a few catbacks, but never a turbo housing. I just bought KPG's k16/k24 z/c turbos. So they would need tore down for this to be done? I would go with the extreme temp matte black. On turbo cars the chrome coating does not stay looking good for ever. It can discolor. I may do the exhaust in the chrome coating. Then do the turbo's in and ported headers in matte black. Comments?

 

swaintech????

 

yep that's it......swaintech.

 

those were from UMW, so they should already be coated if i am not mistaken.

 

Kevin at ultimate motor werks said do not have the inside of the headers coated. Out side is fine but inside can come off and ruin turbo. I had an older camaro and had headers coated inside and out and it is supposed to help the steel headers last longer. Our manifolds are stainless steel so there should be no reason to do the inside. I would however port the stock manifolds and clean them up a bit.

 

It is my understanding that one SHOULD NEVER CERAMIC COAT the INSIDE of the headers. The coating has a tendency to flake off and go right into the turbo and could cause severe turbo damage.

 

I was thinking of only doing the outside. Is a DYI on header porting snd polishing?
