Heat in the footbox is a real issue, and always has been. In a street Cobra, the exhaust is directly under the floorboards. In the S/C configuration, the header tubes are directly in front of the foot box. Of course some heat will end up in the foot box. Everyone who drives a Cobra knows this.

Fortunately, there are a number of simple ways to mitigate that fact. As said, shoes would be the first step. But there are lots of other options if you like to drive without shoes.

Even though the BDR has stainless skins riveted in the foot boxes, mine were bleeding a tar like substance in the areas nearest the headers.
While I had the headers and sidepipes out for recoating this last time I installed Aerogel XTC 5mm insulation,https://spinoff.nasa.gov/Spinoff2010/cg_2.html

LOVED THIS :

After reading these posts, you would not believe that statement!

Much thanks for actually stating that what my original question was, was in fact VALID!

1. ADMITTING HEAT IS AN ISSUE! thank you Lord!

I have never driven without shoes so need to go there.

I now know there are options should it be a problem when I buy a car.

CASE CLOSED!

I have five plus years and over 11,000 miles in my SPF 289 Street Roadster (I too hate the "slabside" moniker). Yes, as the exhaust runs close to the pedal box under the car heat will radiate to the pedal shaft and thus to the alloy plate that covers the floor opening. We found that either DEI or Dynamat heat mat will reduce the heat. Lizardskin spay heat treatment also will help. Still if you are in socks it will be warm but not nasty. A big block roadster is even worse, a friend that owned CSX3327 has imprints of the "AC" pedal logos on his sneakers after a trip to Watkins Glen (about 125 miles). Also some cars need some sealing of the outer footboxes to the body to prevent engine compartment heat infiltrating the cockpit. Regardless, the SPF insulation is far superior to the AC non-existent heat treatment.

The optional footbox vents are very effective and if equipped you can run the heater blower with the heat valve closed to circulate air in the footboxes. My wife has never complained and believe me she would.

Bottom line: We have several 289s running around have had no complaints of heat from the owners.

Appreciated.

Once I purchase something I can do a further investigation if needed

Drove a 427 with under floor exhaust at 40°C (floor mounted pedals), stop-go. No issues. Colder even at speed. I also had a S/C with 2" primaries. The secret is to get air flow under the hood.

That video is click-bait. I didn't watch it. "1" dom - "NIL" video.

Whoever that dude is, I am jealous - that he makes money with this BS.

Having driven my 289 roadster 270+ round trip miles on a 85-95 degree, hot humid day a few months ago while headed to and from a charity Shelby/vintage airplane event, I can tell you that the interior heat was not an issue as the factory heat shielding and carpeting worked as it should. Car ran well, even in stop and go traffic in the construction zones on RT85 south. I of course ran out of cold fluids about 20 miles from home, and had to stop to top myself off as I was feeling the heat (no pun intended). Otherwise, an uneventful, fun trip, and a great event.

Ok guys this is my $.03, Now I've only road raced for 40+years, drove tanker trucks for 30+ years, spent most of my adult life behind the wheel of something. NEVER, NEVER drive in just socks (sheeeeh) come on guys, if you have to hit the brake pedal HARD!!! Try it just sitting in your driveway, SEE IT HURTS (HUH??), and you don't have the control you would with shoes. Anyone that has heat issues with the footbox after trying these fixes (Shoes, heat shield, Nomex , etc) maybe shouldn't be a Cobra owner. Not trying to talk you out-of-one, but Cobras are LOUD, Smelly, rattly, and HOT. I hear Corvettes are nice, and comfy. Cheers TommyRot. P.S. this guy in the video, is a punts

Seriously, What is the obsession with beating this stupid mention of driving without shoes to death?

That has absolutely nothing to do with my question which has been completely deflected and ignored by most for some reason.

Let's get a few facts here:

The individual is a popular auto reviewer, note, I did not say "respected" because we know that his million subscribers are all posers right?

2. He said, he was NOT wearing shoes due to the fact he could not heel-toe due to the pedal placement in the CAR THAt SUPERFORMANCE GAVE HIM TO REVIEW! - Maybe read that twice.

3. Note: He did not say his normal pattern before every review is to remove his shoes since he is some kind of monk perhaps.

I have posted comments several times from real people who were WEARING SHOES that stated the dam heat build-up in the footwell can be a problem for some, extreme for some, and not even present for some.

Some of you I see really took this personally and have embarrassed yourselves by making his foot attire the issue!

IT AINT!!!

I'll drive a few and buy one or two and report back.

I am sorry that asking a simple question was met with far more attitude than helpful information.

And my fav is the judgemental comment about me being a newbie. Really?

I would love to share some pics but cannot seem to get posted.

Good thing I didn't ask a political question!

thx again for the guidance.

So some newbie just discovered this? Geez.

The driver's footbox is hot. I wore sandals most of the time.

The passenger side is even hotter.

When someone asked me if the Cobra had a heater my response was "yes, 427 cubic inches worth".

I'm surprised no one has mentioned Matt Farah's review of a car he claimed to be a real Ferrari 250 GTO that was actually a replica built on a Datsun 240Z: https://www.ferrarichat.com/forum/th...50-gto.286464/ He claimed he saw the 12 cylinder motor right up until the time he was murdered by a cruel gang of facts on a few forums. Regarding heat protection, I've used the DEI stuff on my Healey, it really protects against the muffler heat.

The video is 17:37 minutes long, and if you take out the key fiasco, and the complaint about his flaming socks, it is at least 16 minutes of pure praise of the small block Cobra!

@chupee, I have to agree with most of the rest here, I truly believe you have a chip on your shoulder, whether before the first post or after, (Remember) you came to us. You asked a question and we answered it. DONE. As far as the Puntz, on the video, if he couldn't drive it safety, he should have never taken it out!!! But like most of the FREELOADER'S, he would never pass that chance up, to drive a car he could never afford!! TommyRot.
