I am getting ebat kit black ceramic coated so it should be good to about 2200 degrees or so. Im mainly curious as to how hot the external temp will be. Some of the hot parts are close to power steering lines and Im wondering if I should worry about em!

 

1400-1500 degrees F. Thats at the surface and worst case senerio. Anything within an inch will need to be coverd in some reflective material.

 

Yeah I agree with the post above, it does a good job of retaining heat, but its nothing close to touchable. I would protect thing's around it the same as if it was not coated.

 

Just put the protection on the things that need it as opposed to on top of the coating. The ceramic coating does not like things covering it and will quickly burn off and you will rust.

I like the Thermo-Tec insulating tape with the reflective side out, add a SS hoseclamp or two over it for extra retention. I also use pieces of Earls thermal sleeve with the orange silicon coating for hot and very close applications.

Is that 1500 degrees for the turbo itself or the hot piping?

 

Bump!

 

Thats what we were seeing about an inch off the exhaust port with an EGT sensor under full boost. Coating the hot pipes or wrapping them will greatly reduce undr hood temps. Like a post before don't do both because it will take the coating off. If you can see the pipes glow then they are at least 900 degrees F. I've had plastic harness loom melt off a harness that was 3-4" away from the pipe.
Think of it this way, what would happen if that power steering hose melted through and the fluid sprayed onto the pipe? Instant fire that will be very hard to put out as it is oil fed.

 

I understand, Im just trying to figure out what temp heat shields I need. looks like Im going to get steel braided lines for the power steering

 

You must use line rated for power steering on the high pressure side - not all braided steel lines are. And the high presure side requires special fittings that match the hose used. It would be best to have a reputable hose shop make up a custom high pressure hose for your needs. This is an area that can kill you or, as mentioned, set up a heller fire.

Do you know what rating PS lines need to be?

 

I wanna say 2000psi but check the Earl's plumbing site (www.holley.com) and look at their PS hose. Tough stuff. Remember you only need it on the high pressure side - the pump output to the steering box, and the fittings need to be rated too. The return line and fittings can be low pressure stuff like oil cooler line.
