Yup, all thanks to your suggestions that i have a cool RX8. Winter lasts here only 3 months but still never reach below 1 Degree centigrade even at night time. The rest of 6 months are summer in which AC will be on all the time and for 3 months season is medium ( around 20 Degree centigrade, so i think 180F at full speed will do best. The best part is that That cooling MOD kit will trip the fans automatically when car is cool enough so there is no issue that i have to run the fans all the time

.. Also will foam radiator from Below and corners properly when my engine under tray arrive ( which i already ordered). Already sealed upside of the radiator perfectly. Also New ignition( Plugs, wire and coils) will arrive in 2 to 3 days that will take care of that idle little missing at 1k RPM from one tail pipe as 2 plugs are not giving proper current ( mechanic showed me this on screen), so i ordered full ignition instead of just plugs. I believe there is no compression issue as car starts instantly when hot. Staying overnight, after 24 hours, it starts in 3 seconds which i believe is the plug issue. Will also Gut CAT. So, yes, all in all, i have prepared best for the summer

Again, thanks a lot, i learnt so much from you and other members about how to keep a RX8 in hot weather and also learnt the important ignition system and CAT issues

 

Great news! Glad everything is sorted. Remember, just because the fans turn on at 180F doesn't mean the temp won't go above 180F. It can get up to 210F+ in traffic. So it's still a good idea to monitor your coolant temps

Good luck and stick around in the forums

 

Yes, will keep an eye for sure

 

You might consider buying a wireless OBDII adapter for your car. The location in the RX-8 is just right so that you can keep it plugged in while driving. I bought an ELM-327 with WiFi but you can get one with Bluetooth, too. Then you download an app on your phone and connect to the adapter so you can see the actual temperature as well as some other useful/interesting information. I think mine was around $25 USD.

 

this may be a bit of a dumb inquiry but I just browsed this thread;

at what point, or what temperature, does this become an issue? Ambient temperature, I mean. You would think running in warmer climates would be something basic in the R&D of a car's cooling system, and indeed the rx8 seems a very thoughtful vehicle despite its inherent design complications.

just curious in what climates to be concerned about running the AC. It doesn't get very hot in Wisconsin, but I'd still like to be educated. :P

edit: yes i did see this post
can anyone confirm/ more importantly explain why this would be an accurate target temperature for this issue? just wanna be aware of what's going on inside my 8 to be a good owner

 

According to chris from BHR, RX8 cause heating problems after 37 degree centigrade with AC on, So its better to get prepared because i live in an area where temps are higher for 6 months

 

I cleaned my CAT today. It was choked but now it is shinny clear. The question i want to ask is that i notice a little blue smoke under the hood under the upper tray ( Where Renesis multi side port is written). this happens when car is warmed up. is this normal or should i have to worry about it?

Is it because i cleared the CAT with acid and water mix and now the acid is burning from front exhaust side under the hood?

 

You can clean cats? All I did was break everything inside it and make it an empty barrel. Not too sure about the smoke man. I'd be worried if I were you. I'm sure someone else on here can answer that question.

 

Yeah Bro, Cat was cleaned by my electrician through Acid and water mix and nothing broke off, infact the car sounds very quite and consistent. Finally got the the smoke figured out. it was the acid gas coming from front exhaust end when i cleaned the CAT.

Also bought OBD2 Bluetooth device for temps and checked today, fans starts at 98 degree centigrade and off at 94 degree centigrade

 

Imagine how much our mechanics do here without breaking anything.. Also Coolant light came on. so My mechanic just took off the reservoir bottle, cleaned it with ACID and then water, then cleaned the sensor and Boom, Light was gone.LOLS , its cheap labor here, All of cat and water bottle cleaning was done in $10.. really amazing

 

Whats the best app to download? is it free or not?

 

Cleaned the bottle with acid? Plastic and acid go great together.....

And yes you can clean a cat if it is not damaged already, it needs to be checked first. Results vary however. But a cat that appears to be in good condition can still not work correctly so just because it is not melted or broken up doesn't mean it is good. This is why the proper way to test one is to do a catalytic efficiency test.

 

He did not specify what kind of acid was used. Different types acids do not react with everything. There are acids that do not react with plastic, but will with glass, hydrofluoric for example. So it is kept in plastic containers. Chromic acid can be stored in plastic for short periods say a year or so, but will eventually begin to seep through. So it is completely plausible. Although this is the first time I have ever heard it being used in this way.

 

Those are good temps! Make sure you check the temps during the day, at noon. Specially in traffic! These cars don't do well with slow moving traffic in hot weather. You need to keep the car idling/in traffic for at least for an hour. That should give you a good idea on how high your temps get As a bonus, take it on the highway after that and see if your temps drop.

If you have an android phone, Torque is the best There's a free version but you can get the paid version for free as well. I did

If you're on iOS, you're out of luck. Buy a cheap android device. That's what I did

 

Honestly, why go thorough the hassle of cleaning it with acid and then doing a catalytic converter efficiency test? You don't know if cleaning it really did the trick. Like 9krpmrx8 said, it could be pretty messed up even though it looks good from the outside.

You don't have emission regulations over there. Gut the cat. You'll have more power, it'll sound louder, and the cat will never pose a threat to your engine, ever. It will be fine for the rest of the car's life.

Gut the cat and call it a day.

 

Yeah right,it was a mild acid which only cleaned the rust from inside of the bottle

 

How to get the paid version for free? im not on IOS

 

To get the paid version of Torque for free, simply give the developer $5 for free, and he will give you the paid version for free.



Seriously, it's $5. It's the cheaper than the adapter you are using. It's cheaper than pretty much any tool you will use on your car. It's cheaper than any part on your car. Just pay the $5. It's worth it.

This should work.

 

Monitored temps today. Max it reached with high rpm and in sow traffic is 102 Centigrade and then went down to 95 after 3 or 4 minutes

 

Thanks, installed it, it works great

 

Great. How long were you stuck in traffic? Did the temp go back down to 95c while you were idling in traffic or moving?

 

Yes, after reaching 102 degree centigrade , it slowly went down to 95 in about 3 to 5 minutes in slow moving traffic and idling mix

 

Those are good temps. But it's only around 70F over there. So keep an eye on it in the summer. Drive safe bro. Good luck!

 

Thanks. yeah its only 70f here, thats why i am doing the cooling mod with radiator foaming from sides and under this week after my engine under tray arrives. Also this week, will install the cooling fan kit from rx8performance.com

Also can anyone guide me about the front bumper grill as shown in the pic below

There is a grill behind my front number plate. on the inner side there is a shield which don't allow air to pass freely into the radiator. is it stock or should i remove it for better air flow?
