Well I ripped all my interior out to install all new, and I am working on dynomatting the whole inside. I thought I would run the car for 15 minutes since I parked it for 2 weeks and have had the interior light on and off frequently. After about 15 minutes I noticed the floorpan near the gas pedal and on the passenger side same area getting so hot that I could not even keep my hand on it for 2 seconds! Looking underneith this is exactly where the collectors are from the Hedmann Headers below.
What can I do to correct this? Exhaust Shield of some sort maybe? Thermal Coat the inside of the headers/collectors to reduce heat? Anyone else have this problem?
Obviously I am touching Fatmat which in turn touches the floorboard directly and I am sure with the Jute padding and Carpet on top of this all that it won't be as hot as touching it directly but there is alot of heat entering this car thru these floorboards that I'd like to prevent if possible. Also I was parked in the garage so I am sure they don't get as hot while cruising on the road with a flow of air.

A sheetmetal shield should do the trick if there is enough space to install it . Space it away from the collector so as to not allow the heat to telegraph to the shield . Good luck man.

I wouldn't worry about it. I'd imagine any similar car with headers would do the same thing under those conditions.

I had a set of Hooker Comps on mine once and took them off after 20 minutes of run time because of the same reasons. The #8 tube was just too close to the floorboard.

A heat shield will go a long way. The foil-fiberglass sandwich type work well. If you have any exhaust header wrap you can use a sheet metal shield wrapped with the header wrap. Keep as much of an air-gap to the firewall as possible. If the headers do not have an external ceramic coating I would highly recommend getting it done.

If you have electric fans on the car have them running while the enging is on to keep the airflow moving. Also, if the hood is off the headers are not getting full airflow and more heat will transfer to the firewall and surrounding areas.

Just an observation.....
If you were running the car in the garage for 15 minutes...I'm surprized you can still breathe, let alone type!!!

Before you go to all the trouble of adding heat sheilds, removing/replacing stuff, take the car out for a 15 min spin and see if it really is an issue. Even stock cars will heat the floors a little. If it is excessive, then check for clearance. The header/collector should not actually touch the floor. And I'd try the wrap first. Just a thought.

Talking

Along the same lines but to change the subject.

My Mom bought the only new Ford she ever got which was an early '80's, 4/D Maverick. The converter caught on fire while still under warrantee and the Dealer didn't do anything about it except give her a new set of cheap floor mats to hide the burnt rear carpet!

Needless to say, that's why she NEVER bought another Ford!!
