2004 R T 10 How do you mininize heat generation in passenger area

[daddyo]

I am in FL and am looking to purchase a 2004 R/T 10 with a Paxton supercharger. I have read that a common complaint for this model is the engine heat getting into the passenger compartment. Can this be minimized with the addition of heat/sound deadening material beneath the carpet (both floor and firewall)? Any other suggestions for how this can this be minimized?

Thanks for any guidance!

Get rid of the exhaust cross over and you are set . PS It's an SRT-10..........lol !

Hi Flow cats also help.

My bad! Was trying to differentiate between the convertible and coupe. Will learn quickly! Have owned and restored Mopars for 40 years and more familiar with the older muscle cars. Just sold my 2005 SRT-10 Ram. Is the cross over is an H pipe or X pipe and is it located that close to the firewall?

Thanks!

Ask one of the bigger Dodge dealers that repair Vipers for a GEN IV exhaust, that will reduce cabin heat and last a long time too.

Thanks for the input! I did a little homework and found a pic. of the crossover. Looks like the stock setup is parallel pipes (very close together - center of car) with an H pipe. Guess this is too close to passenger cabin. Sounds like some easy fixes to this matter.

The 2004 (gen3) goes along the sills, crosses over behind the driver/passenger then out the opposite sides (see picture). The later models (gen 4&5) do not cross over which is cooler but living in Florida with an ‘04 too its hot and humid in the summer no matter what you do :)36701

Installing high flow cats, or going catless, and putting in a Gen IV or aftermarket exhaust will greatly reduce heat.

However, if you are still not satisfied, then installing a FatMat or Dynamat will definitely help with heat reduction. Sound deadening will help more with sound and is installed on top of the FatMat/Dynamat.

Just for reference here is what the corsa system for a G3/4 looks like. On a G3 it eliminates the crossover and on a G4 slightly changes the sound.

A Gen 4 hood will also eliminate much of the engine heat from wrapping around the A pillar and coming into the car.

My approach on my Gen 3 was to retain the crossover but remove the cats. A simple test to check if your cats are working is to measure inlet and outlet temperature of the cat at idle with an IR thermometer. On a functioning cat the inlet temp will be ~300F, the outlet ~500. By removing the cats I get a 50% drop in heat (from ambient).

When I did this I did one side at a time. After a test drive, the side with the cats was hot, the side without not.

Thanks again for all the input! The current owner said he has already eliminated the crossover and has straight pipes without converters. He also suggested it's a bit loud! I should find out soon.

Cheers!!!

If it is too loud for your liking let me know. I have my old GenIV factory exhaust with only 2,000 miles on it stored in my basement. It
is full with cat's. Not sure what it is worth but it is in like new condition.

Why is your basement full of cats?
