i have a set of gotham hard intake pipes with a pettit intake and an opened up front inlet and i notice that after running the car that the pipes get F.ing HOT! in fact, i've scorched my hands several times on them. has anyone wrapped hard pipes with header wrap or had them coated w/jet hot or a similar coating? i have to believe it would help with intake temps to some degree.
thanks,
andy

 

I wraped the turbo inlet pipe, but not the intake pipes. The inlet pipe gets really close to the Y-pipe.

 

Im in the same boat considering the same thing. This article is very interesting. I spoke with the cool products guy who says he has made applications for fd race teams but does not have any templates in stock. Coating the shift tunnel to keep heat out of the car was my original thought. Now Im thinking intake, and intercooler pipes. I like the blow torch test

the turbo wrap in the second article is pretty cool too.

if you call the guy please tell him you are from the rx7 forum...I would like him to give us group buy or club pricing. I havnt decided if I am going to buy his stuff or not...If you decided to, keep me posted. I know of 3 others interested. We might have enough for him to lower the prices.

 

This is an excellent idea. So many guys spend so much time and money on expensive mods trying to bump hp, when this will bump hp, supress detonation, and increase component life and is EASY to implement.
I think it looks good also - so NASA!

I went to a fair amount of trouble (and practically no money) to ventilate my engine compartment using the stock naca vents behind the wheel wells - the difference in underhood temps is remarkable. It now literally breathes they way Mr. Chin originally designed it. (He said this in an article)

I know before I spend another nickle on go fast components this will be my next step. I especially like the idea of insulating the underside of the intake manifold. Time to find some good material and whip out the ol' industrial sewing machine and some Nomex thread........ The fabric he uses is commercially available but it is NOT cheap.

 

sort of on the same topic, has anyone used a headlight cover fresh air duct or anything similar. i see that jt imports has a knightsports cover for less than $200.00 that fits the cover on the intake side of the engine. also, ronkmiller, pics of that naca duct ventillation set-up would be greatly appreciated as i have now become completely neurotic about underhood temps since a false alarm thinking a coolant seal crapped out.

Ceramic coating really works for sealing out/in heat, but the big question is, what do you coat under the hood? Some things are no brainers like:

1. Downpipe (the air inside is a HELL of a lot hooter than outside, so the coating protects everything around it from radiant heat. Same would go for everything in the neighborhood like Turbos and exhaust manifold?

2. Intake pipes: Theoretically you're bringing in cold air, so the ceramics would protect that air from radiant engine/turbo heat... BUT:

What about turbo/IC?manifold piping? I can't imagine you'd coat the piping after the turbos, but befor the IC, because the temperature of that air wouldn't necessarily be alotcolder than the ambient underhood temps... and uncoated pipes might actually SHED some heat.

After the IC?
Maybe. Good IC's leave the outlet pipe cool to the touch, so presumably the air inside is cooler than the underhood ambient temp. Therefore the pipes wouldn't shed any heat, if anything they'd absorb it from the underhood heat (heatsoak). so the caramic would be great from IC outlet to LIM?

Engineers? Help an art major out will ya?

 

As far as our engines and most things go, heat is absorbed, so you would want to minimize the amount of heat touching the IC piping, after it has been cooled. Insulating components that give off heat, while reflecting the radiant energy would be the most logical idea; most likely including various forms of insulating the IC elbow etc. as well.

Basically, you don't know why you would wrap the Y/X-over pipe? Simply put, the Y/X over pipes will be hotter than the air temperature in the engine bay where air is roaming freely; plus it's also hot air, traveling through a confined area of space (similar to your DP, MP, and CB), which doesn't allow it to dissipate (thus cool) as well. As far as leaving it open to 'shed' heat, yes it will- but not enough to make a noticable difference. Even so, the air is traveling to the intercooler anyway, so the amount of heat it would 'shed', is in no comparison to the amount it WILL shed when it passes through the IC- and if you have a FMIC, it makes it even less of a problem (with the tradeoff of course being radiator/water temps). However, if your goal is to block radiant energy from heating other components in the engine bay (like you do with the DP), the Y/X over pipe will be one of those sources that should get attention...just touch it and you will see.
