Sup all.

I'm installing a T-78 kit, but i just purchased some heat wrap, tape, and tubing to do my engine bay in. I notice that a lot of tuners wrap near everything in tape,wrap, tubing when installing a larger turbo.

My question is, how many of you have done this also? Have you noticed any differences in underhood temp? power?

I'm wrapping my manifold and downpipe in thermotec headerwrap, using DEI heat tape to do the paint/firewall/strut tower, and a/c lines as well as other vacuum lines and such. Also using DEI heat tubing to do all related electrical lines/wires running around that area.

Just seems worth doing it.

I haven't wrapped my mani/dp.

But I have been using the ThermoTec Cool-Tape to wrap all my wire looms.

I like the Cool Tubes that they have too, but the Tape is more heat resistant (2000F. Sure its overkill, but what the hell.)

Post some pics of when you are done...

hey u might also try ceramic coating of ur exhaust ports.. and all ur intake/ exhaust pipes

I just did a search on this a couple of days ago. It seems everyone agrees that it greatly reduces underhood temperatures, but I don't recall anyone claiming a difference in performance. It's not uncommon for people to say that the wrapping retains moisture, leading to corrosion and rust.

Someone suggested applying 1500* paint to everything before it's wrapped, then painting again after wrapping. Whoever it was that said that claimed he'd had that setup for some substantial period of time without any negative effects. It definitely sounds worth it to me. Really, the paint couldn't look any worse than the flat brown tape.

Another chief complaint is that wrapping the manifold robs it of necessary heat dissipation, leading to increased engine temperatures. No one has really been able to confirm or deny this with proof. It would be VERY nice if you could supply us with water temp and EGT numbers.

Anyone have thoughts on wrapping the INTERCOOLER Piping?

I've seen a few people to it.

RickBusarow

Well, which is warmer, the air outside the intercooler piping, or the air inside? I'd wager that the charged air going to the intercooler is warmer than the ambient air, and the piping allows for a very small amount of that heat to dissipate. I'm not as sure about the cooled air, though...

i don't plan on wrapping my turbo, just the things around it to "reflect" the heat. I'm wrapping my downpipe and spraying it with the silicone, which avoids the rusting and dirt..

sigh....... why not dont worry bout the tape... and ummm CERAMIC COAT... no worries bout corrosion... and as to wrapping the intercooler piping... if u have a cold air system... then coat those pipe... im coating all my exhast and intake pipes

Wrapping the exhaust housing and downpipe/exhaust will increase the exhaust energy (marginally) and improve turbo spool due to less exhaust energy being dissipated into heat.

The abuse on the components involved is probably not worth it though. I would think a vented hood is one of the best ways to reduce under hood temperatures.

I'm with you Dougie!! I've ceramic coated EVERY single intake/exhaust part between the intake filter and the catback (except for the shortblock of course.)

Pete give me a call and stop by to see what I'm talking about. It'll make a believer out of you!

heh PM me your phone # again carlos.. my phone got ran over by a truck a while back.. thanks

twinturborx7pete post some pics of your engine bay when your finished. I in the process of doing the same thing.
