Had to remove the under-the-hood insulation last year. Haven't had time to replace. Don't really hear/notice any difference. I'd rather spend my money on other goodies. Do I run risk to paint or finish by running without the insulation?

 

The stuff was gone when I bought my '86 and no problems to report..Paint is untouched by any extra heat.

 

The factory didn't bother to put it on the later 951's (MY88 and 89, IIRC), so evidently they decided to spend their money on other goodies, too.

Regards,

 

The only real important job the hood insulation does is prevent the plug wires from grounding to the hood in 944S's. This was a service note in the porsche parts book. My 89 951 never had it.

Just on Rennlist, but from a number of different folks. Sorry if I can't recall exactly what cars didn't have it, but I am almost positive at least the '89 951's don't have it.

Sounds like a whole lot cheaper to pull it out and clean the inside of the hood up than put new insulation in at a $100 for the two pads?

 

My '88 Turbo S doesn't have any hood insulation. No problems with the paint to date.

Couple of reasons I replaced:
a)worried about the hood grounding out
b)insulation helps keep the heat from melting your MasterCylinder cup
c)it looks so much better with new insulation than old peeling insululation or the residue from removed insulation
d)the job is so easy and not that expensive.

Call Vertex or Paragon or even your dealer (you may be suprised by their competitive price) and find out how much they sell it for. <img border="0" alt="[king]" title="" src="graemlins/r.gif" />

SWEET Color!

 

How do you get the old glue off? Has anyone found a good solvent that doesn't affect the paint?

Edit: Found this.

Here's another tip for the removal process: Use Naphtha solvent to remove the adhesive from the hood. It is available for under $5/quart from any decent sized hardware store in the paint/stain section.
This product did not harm the paint, although it is extremely flammable. I believe that it is similar to the chemical that is used in cigarette lighters, so be sure to open the garage door for this project!

I filled up an old hairspray bottle with the Naphtha, and used it to spray a small area at a time. A plastic scraper and some paper towels were all that it took to remove the old adhesive.

It took about an hour. I put some large plastic sheeting over the engine bay and used a standard spray bottle and continuously sprayed tons of naptha on the glue. I used a plastic ~2" wallpaper scraper to remove the glue. I'd scrape some, then go back and spray more naptha. You really need to saturate it.

 

Huh...not there on my '88 951...Can't see putting it now...Or am I missing a reason...? Seems like it would maybe HOLD heat as well? Just curious...

 

ELLSSUU,
I was just wondering where you got your vented nose panel and your front spoiler. They look awesome by the way.
