I finally found a shop who'll weld in my SFC for me.

to start with, I have a 91 RS v6 auto trans.
single cat and as far as it seems to me, should be a simple welding installation.

but the shop told me that since I dont want them to take the carpet out(caz they wanna charge me more if i did),
the carpet might burn.
I sait "its ok caz im getting a new carpet soon so I dont mind a burnt spot"

and here's what he said..
"no, I mean, it might catch fire and ur whole interior could fire up"

OKAY... is this really possible or what?
I really dont care for a whole or burnt spot caz I really am changing carpet,
but I dont want fires either, is it possible to catch fire?

Just wet it down if you're worried about it.

When I was doing mine I had a squirt bottle ready and the door sill plates off to get under the carpet. The padding smoldered a bit and created smoke but never got any bursts of flames. Gave the spots a few squirts of water and called it good. The carpet itself was untouched, just the padding got damaged (which will be replaced anyway like you're doing).

I've had 2 cars done, no fires.

I'd say the danger is pretty high.

Think of the liability the shop is taking, but doing that job. Would they really want to chance it? If they did start a fire, and had to lower the car (takes 30 seconds say), get a jug of water, and put it out, by that time you're steering wheel and seats are charred, and you're PISSED OFF!

remove your carpet for them. When you get the car back, put it back in. Inspect your wiring guides (the black plastic wiring router thingies) after you get it back, will probably be smoked).

No fire here. I removed the door sills and lifted the carpet away from the floor pans where the welds would occur. I didn't have a water bottle, but the idea is a good one.

I also never was even asked to remove the carpet. They just welded away. I think they pulled a sill and slid a piece of fire retardent mat in there or something. Kinda like those "stop fire" blankets that they have in labs. Slip it in there and do what you want, no fire is getting through those things. If you havea highschool neer by or are in highschool, I remember seeing them in the labs that we had, or any science class that had a lab. "borrow" it or just ask.

There is no need to have to take out all the damn carpet. I am a firm believer in doing a job the right way, but I am also a firm believer in not wasting time if you don't need to. Shove some fire retating thing in there and you will be just fine.

When I welded mine on...I got fire. That stuff under the carpet goes pretty fast if you arent careful. The only place I had an issue was when I welded the cross braces to the floor board. Not even sure if you have to do that...but I did it. Just so you know it CAN happen. I used pieces of 2x4 and jambed it under the carpet to keep it off the floor. When it would catch, Ide just do as suggested above. Hit it with some water. But for welding to the pinch seam...no...you wont have much trouble. But if you are welding along the floor as well...Ide atleast take off the rocker covers and try to move the carpet away some.

Better safe than sorry right??? For the 5 minutes it takes to remove the screws and get the rocker covers off... better than replacing seats or more if something goes wrong.

I agree with Sonix,
When I had my sfc installed I pulled the interior, but if that is too labour intensive, pull the sill plates off, and at least pull the front seats - roll the carpet up towards the centre consul - this isn't hard or really time consuming. You'd be surprised how that little flame can spread! Another thing to consider - if you pull the carpet or at least roll it up out of the way, you can spray a light coat of rust preventive paint over the fresh welds - this will help slow and or prevent any rust from forming.

For unknown reasons, I have heat damage to the floor on my car, posted about it here

The insulation showed no signs of catching on fire but was pretty seriously discolored. The paint was not stuck to the metal anymore, it was burned to a crisp. I'd have to say it would have to get REALLY hot to set the insulation on fire.
