Solutions for heatsoak

Anyone had any noticeable results from this stuff from DEI?

I'm about to take off the intake to put in some Accel 48's and was thinking of wrapping the intake and fuel rails, fuel lines, fuel dist. block...heck I was thinking of wrapping the intake tubing and when I put the roots SC, make a shield for that as well since it sits under the exhaust.

the question is do I need reflection of heat or insulation of heat if I used header wrap?
because on a 90+ day I can literally burn my hands touching the intake and fuel lines which are anodized al., any input

I wouldn't do that as an intake on a stock SHO will be hot to the touch. If you wrap the intake it will keep the heat inside driving up temperatures. It only works on things like exhaust piping. Right now the intake is acting like a gain head sink for the motor.

If its an issue get some thermal spacers from Josh and that will be enough to cool the intake as it would no longer be attached to the engine.

I wouldn't wrap the fuel rails either.

Yea, I was thinking most of the heat would transfer from the intake connection to the heads, so i think the only good place would be on the fuel dist. block and connectors, air intake piping if its metal.

On a side note, what suggestions would you have for the water-to-air intercooler setup w/ water cooler, ignoring the pump and lines, I'm trying to figure out how I would keep the reservoir tank cool, which would be in the trunk.

I plan to run coolant/water mix so i don't want to keep adding and draining it with coolant, ice and water so I was thinking to put the reservoir inside a regular beer cooler, and then packing the beer cooler with ice around the resevoir, I think the heat transfer through the aluminum reservoir would be a lot less that the heat transfer if I put ice directly into the coolant/water mix but what I'm confused on is the water cooler, if its worth putting one on, give me some feedback on that

After thinking about this on my way home, putting ice around the reservoir would probably melt within a few miles, since the water would be stagnate<spelling, anyways

As stated by LOUDSHO92, insulating the intake or runners will only keep them from dissipating heat. Phenolic spacers between the intake and heads and finding a way to extract heat from the eingine compartment(exhast wrap and some sort of cowl/vent) is probably the best thing. As far as keeping the rails cool, I'd look at cooling the fuel that goes into them.

I have used the DEI stuff with great sucess.
The best wat to get rid of heat soak, naws!!!

No need for the phenolic spacer is you just do the TB coolant bypass (assuming you don't live in N Minnesota where it might freeze up)
I can put my hand on the intake after driving and it is barely warm to the touch. THat wrap would be good for sealing up headers though.

Short of running a refrigerant system it wont last long. The only thing you can really do is an air to water cooling system and it will help a lot.

I'm no engineer but I'd have to say the intake will absorb more heat from the heads than the relatively small cavity in the TB area. Point being, phenolic spacers would help.

 

[shobote]

You would think so, but I can touch the runners and surge tanks after running it and they are not hot at all; before the TB bypass, it was way too hot to put my hand on either, so the heat transfer from the heads is apparently insignificant; the intake charge itself must be cooling the tract.

the coolant doesn't heat the intake through the metal; the coolant in the TB heats the air up (a lot; you'd be surprised), which heats the intake up. I've noticed quite a drop in intake surface temps after doing the coolant bypass mod too.
