Anyone ever wrapped their crossover? Just did this mod to my 97 GTP, lowered intake temps 15-20 degrees on average.
I figure with a turbo blanket & the crossover wrapped that should help the transmission live longer also.
Any input...
Thanks. :D
I wrapped my intercooler to TBI to lower temps. That air delivery tube gets very warm and defeats the whole idea of the intercooler.
There was a thread somewhere that we all discussed wrapping the downpipe, and if you wrap it too tight it slows exhaust velocity, but I don't see how it could be a bad thing because the factory pipe came with a heat shield. Let me know if it lowers temps under the hood, I have some extra wrap laying around.
I used the reflective heat tape for BOTH IC pipes (noticed big differance). I guess I'll wrap my crossover and see what happens.
wrapping some type piping will cause condensation between pipe and tape and cause rust. Get some good tape!
Thats why they sell the protective spray to apply after you wrap it :)
I have my jeff m. crossover ceramic coated in flat black. retains heat to 1400 degrees. I had that done for about $75.00 i think, have the turbo compressor housing and upper and lower intake manifold done in chrome too but the chrome color is only good to 1100 degrees and is more expensive. powder coating (no heat retention) would have been cheaper but this guy treats me right on the prices for the quality he puts out. as for the black, i did the exhaust side of the turbo, the exhaust manifolds and the crossover for like 200.00, and the chrome colored stuff was about 300.00. the chrome stuff comes so clean you can hose it off and it looks like you detailed it.
What'd that cost you?
Do not wrap the exhaust manifolds or the crossover pipe on a turbo car if you want it to last :shock: (pro-racers don?t care how long things last, especially some headers then can replace cheap and easy so you may see pics of wrap on their pipes). This is not my opinion but a fact stated by even the manufactures of ceramic fabric wrap, and I have read this in a number of car books as well as all the SyTy and GN guys I know avoid this. Any turbo car is at risk of wrapping before the turbo. With the fabric there is no way to ensure a uniform covering and differences in temps will cause different rates of expansion fatiguing the metal, but worse is the thermal wrap works so well at holding the heat in the pipe that the metal can get too hot and crystallize, major failure then! BUT sprayed on/baked on ceramic coating is great, the thick stuff that is not shiny but is grainy and rough is the best for maximum/safe heat retention. As for a faster spool up from wrapping, with a bigger turbo for sure but think about this little T25 being feed by a big 3.1L motor, there is no lag to need higher spooling exhaust. Reduce the engine bay temps for sure and those who wrapped their intake pipes gain best there.

Good points, and well taken.
Are there any other alternatives to the pricey "jet-hot" coating? with a base price of less than $1000 for the car and already well past that in the motor.... :?
edited my post above so check that out
Thermal coatings out there run around the same price, Jet-Hot is one but their quality control is slipping a bit, not all their work is this way but I have seen too many goofs lately. Good ones I know of are Swain and High Performance Coatings, there are a few more but drawing a blank this late at night. There are many more new coating shops opening up with the Asian cars driving performance so much.

Maddux31,
Any pictures of this plating??
