yes, another side sill repair question

[JST2CRZY]

I need to have both side sills repaired and have read through nearly every thread on this subject. My 96 gts has headers, Borla, and no cats. The stock insulation is in pretty good shape except for an area on each where the cat was.

I will be adding vents front and rear. Has anyone tried a high temp paint or coating on the inside of the sills? Also, I was thinking about going without the insulation. I read that several people have done this with good results. If any of those individuals are reading this, how are the sills holding up?

Thanks, Bill

I used Jet Hot coating on the Borla exhaust where it goes through the side-sill. This has worked very well, even on the stock cats, which were opened to 3 inches. I have not had a heat problem for 15,000 miles.

is the jet hot a DIY thing or did you send it off somewhere

Thanks, Bill

where are you planning on placing the rear vents? i thought the fronts is all you need to get flow going

i dont see the reason to take the insulation out. why do it ? whats the point ?

My brother painted the inside of his sills with a heat resistant coating but left the insulation in. His main concern was to lower the heat so that white paint would not yellow. His was a 96 White RT/10.

Do not take out the insulation. It needs to be there.

 

[ViperGeorge]

I'm pretty sure dave6666 vented his sills. Do a search there are pics posted somewhere.

I agree with above.

So why does it need to be there on a car with no cats? I've been happy with my gen1.. no insulation sills w/ no cats.... They don't get hot, just warm.

why? because the pipes behind em get over 600degrees. Sure it might be no prob when your crusin and have airflow, but when your sitting in traffic or a long light its basically cooking em.

Jet Hot coating needs to be sent out and is not a DIY.

Check it out:

JETHOT The Hottest Header Coatings! Jet-Hot, jet coat, hot jet, headers, coatings, sterling,Header coating, Ceramic coating, corrosion protection, Metallic Ceramic Coatings, MCCI, metallic ceramic, exhaust coating, performance coating, temperature re

I plan to do this to my headers, flex pipes, and intermediate pipes.

OK, I give.... You're right!! I just don't sit in traffic I guess?? I'll be putting the insulation back in later this year since I need to install the cats for emissions. The insulation is a must if cats are installed!!

(I look at it like this: I'm only 160lbs if I leave it out..)

Side sill heat has been an issue with the Viper from the start. Visit our website, we have many solutions. Venting the side sills really helps.

Feel free to call, I can give lots of advice.

 

[RTTTTed]

Main problem being the Government required Cats.

Thanks for all the input so far. Dan, I will call you next week. Bill

I recommend considering a procedure called Flame Spraying. It's a procedure done by industrial coating shops. To put it simply, they can use any type of metal alloy, and from a powdered form, it combines with super hot gasses as it passes through a spray gun and onto the surface of whatever your spraying. It has the same benefits as jet coating, but some would argue it also has better at both containing and dissipating heat. The finished product on the surface is thick and coarse, preventing heat from getting through. In addition, the coarse surface has more surface area for heat to dissipate from. I had this done on a custom exhaust system I had built for my Corvette ZR1, and even when they are as hot as they can get, I can still touch the header's primary tubes without burning my hand. This might be a good option for you.

FYI - Flame spraying is not designed to be pretty and shiny when done, but if your spraying pipes behind the sills, it shouldn't matter. You can easily find more info on this online.

Just my $.02.

on my 2002 RT/10, I got rid of the stock cats, replaced with high flow cats from Roe racing with their thermal wrap (which is good for temps up to 1200 degrees). front and rear of the side sills are now vented. sills still get warm but will not burn you. new paint on the sills is holding up quite well.

when I pull into my garage, I can feel the heat pouring out of the vents, more so the front than the rear.

red heat: Did you still use the stock insulation?

 

[plumcrazy]

has anyone answered why you feel the need to remove the OE insulation ?

is it weight savings ?

especially on a light colored car, be careful of yellowing without it

 

[red heat]

red heat: Did you still use the stock insulation?

Yes! the hi flo catalytic converters are much skinnier than the flow restricting stock cats. everything fits in the side sill (stock insulation and the new thermal wrap)
