Has anyone here installed the vented cowl or cur out a hole under the driver's side "speaker grill"? If so, did you observe any noticable reduction in cockpit temps? Does any of the heat roll around the windshield and in through the side windows?

Before I decided to invest in a windsheild cowl, I just pulled mine off all-together to see if it got any cooler. The temps seemed about the same with the thing sitting there. Granted thats not raw data gathered from datalogging with thermocouples, I dont think it did much. I have HEARD that cutting a hole in the hood of the drivers side "speaker" works. As with any viper owners, I would love to see anything that would cool the cockpit. I think if a tuner came out with a shielding kit that WORKED at a reasonable cost, people would buy it. Im not talking about the couple of GRRRR that craigin markets, but somethign signficantly less. Has anyone insulated the foot boxes? Would be kinda ugly though....

I don't think it does much Matt. If it did, the factory prolly would have cut that hole out already, or its the first mod that everyone would do.

The only option I know of is to add some thermal insulation to the firewall, but you have to do that pretty much with the motor out, or at least most of the motor out.

I cut the hole in the "speaker" vent and it's the best and cheapest mod I've done! Immediately I noticed a lot less heat in the footwell. Usually in 80 degree and higher outside temps I had to turn on the a/c to keep my feet from frying....not any more. It's amazing how much heat you can actually see coming out of the vent while sitting at a stop light. I listened to every way to do it..from a dremmel to a fine saw, but I got a tip from another Viper pwner to use a 4" hole saw. Went out and bought one and it was really easy and looks clean. Used black epoxy on the inside of the hole to seal where the hood and undercover of the hood meet. It looks great! /images/graemlins/headbang.gif

My aftermarket computer is mounted there and I believe many people put their VEC2's, MSD boxes there as well. If you get caught in the rain, those boxes might get, well...FUCKED?

You used a 4" hole saw? Medium or fine tooth? How did you keep paint from chipping? Im assuming you went outside to in. Fast or slow drill speed?
I'd probably use masking tape over the are and go from the outside in. I think this would minimize the chances of chipping the paint.

It would be tough for me to take a hole saw to the Viper though.

What I want to do is open up the plastic over the wheel well to let the heat vent through the gills over each wheel. If I remember right, I saw a pic of GTS Dean's car and he did that.

Its the brake heat I worry about. Once you have a helmet and nomex suit on, you don't notice the cockpit heat so much.

Where the hell do you find a 4" hole saw? I think you would need a fine tooth one made of a thin material like spring steel.
4" hole saws are available at almost any good tool store. Not that uncommon. I've seen them up to 6" and larger.

Use a variable speed drill and start off slow.

I couldn't do it. I'd just give it to my dealer (Tator) and have him do it.

I heard those things are dangerous to use. Since its easy to apply more pressure on one side than the other, especially if you arent using a drill press and its on an uneven surface, one bit can grab and send the whole assembly walking even with the pilot hole drilled.

Did I ever say you don't need to know how to use your tool? /images/graemlins/supergrin.gif
