HOW HOT is your FD ??
 
Once I drive my FD for any length of time , a lot of heat comes into the car through the fire wall (under the dash) , if I have a passenger , they always remark about how hot it it , also sometimes my car radio switches off and displays "HEAT" on its screen ! Has anyone done any type of custom heat shielding in an attempt to cool things down ?

Mine bakes too. In the summer its nasty. Even up here in washington. I also noticed it comming from my feet. Reminded me of my friends 427 AC Cobra, except his floor boards get so hot your heels literally start to burn through your shoes.

what are all the underhood temps? (water,oil, etc..)

Driving my FD in 110+ heat in Las Vegas summer months is absolutely BRUTAL. The heat from the floor and center console kills me.

hardly drive the 7 in mid July to mid September...AC works but not worth seeing coolant temperature increase as much as 5*C. Hopefully the Scoot hood willl do good this year...

Love driving the Titan in Texas summer mths...ice cold AC

Funny you mention that. I just took some steps to decrease the heat radiated into the interior last weekend.

Besides the heat in the foot well area, I have always noticed how warm the tranny tunnel gets. I had some leftover DEI heat shielding stuff from another project on another car and I had the center console out while I was relocating my battery so I figured I'd put the heat shielding stuff to good use.

I attached a pic of what I did with it. I basically eyeballed the size and cut a length of the material that I thought would work. Better to start with a larger piece and trim down if its too large. I cut a slit over the shifter in the middle of the sheet. Then using my hands (wear gloves) I just pushed the material down under the carpet on each side of the tranny tunnel making sure to keep it straight. Then, using a box cutter, I cut some slits where bolts stuck through and voila.

Makes a nice difference. I'm going to experiment with some of the stick on heat shielding at the foot well area too on the firewall.

This was the stuff I used for this project:

Oh and header wrap on the down pipe and mid pipe help also.

I noticed an increase in underhood temps after I installed the koyo and the Greddy SMIC. I still had the stock airbox but the crossover wouldnt fit any more so it was just pulling air from the bay.

My center console would get hot enough for me to have to pull my leg away. One day I cut the bottom out of the airbox installed an aluminum scoop and capped the hole that went to the crossover. I haven't been toasted since. Still can be warm when driving all day but nothing like before.

when I first brought my FD ( stock ) it used to toast me up real bad after driving around for a while.
Then I did all my mods, FMIC, custom alloy air dam intake, twin pod filters and changed the trans fluid and now I get no heat on a cold day and hardly any on a hot day. I've got a 2hr drive down south tommorrow so this will be a good test.

BTW, I've removed my AC as well but I think the elimination of the AC Rad has helped my air and water temps heaps.

My oil and water temps are better than most since I put in my EWP and tripple pass Koyo rad , I dont think the heat is coming from the rad , I think its the exhaust side of the motor ,although my whole exhaust system up to the down pipe is coated with a thermal barrier , and both down pipes are also wrapped , my exhaust tepperatures never go more than 1200degF at any time though !

I don't have much of a problem with heat, it gets a little warm on the pass side sometimes but not excessive. I use heatshields on the downpipe and cat. Additionally, the tranny bottom cover/shield has not been on the car in at least 10 years, which probably helps air circulation in and through the tunnel.

Note that some of the heat[soak] inside the cockpit comes from the heater core which always receives hot water and always makes the dash area seem warm.

Check you shifter (seals?) The black pieces between the shifter and tunnel. I replaced 2 of them and it made a huge difference. The large one is around $50 from Ray. My car only had 65,xxx miles and mine was rotten.

Get some heat shielding material and place it under the center councel. The adhesive sheet type would work well for this. Ceramic coating exhaust components will also help.

Just wrapping the DP back to the cat eliminated much of the underhood heat in my car. I split a roll with a friend, but a full roll should do well past the cat.

Damn your nuts for driving the FD in the summer in vegas lol

I was there last october and i though i was gonna die. My relatives there told me when you come visit again, DONT come during summer months, come like nov-feb. March and it will start getting warm again. He said in the summer, you dont even want to step outside your house to get your mail. haha

I truely miss that place.

You FD guys are babies, quit your boohooing and deal with it

in scottsdale it was 118 in summer w/ windows down, heater on to keep car from overheating
drink lotsa water and grow a pair :)

Sounds like your FD has a Feva...


And the only cure is more COW BELL!!!
