I purchased the 5/16 motordyne spacer with ISO kit. I have read the majority of posts regarding the spacer, however my question is with the ISO kit and specifically the Coolant Control Valve.

How many of you have this with your spacer? Any issues? I live in South Texas thus 97% of the year the valve would remain closed. That being said does it really make a difference to add this or should I simply gone with the spacer? $25 wasn't a big deal so I got the ISO, but didn't really investigate...just assumed that this would be best for us folks in warm climates.

Thanks in advance!

 

ya the iso thermal spacer is for very vold weather. not for us texans bro but i dont think it will matter, but wait for more feedback because im only sure of the iso thermal being for cold weather, im not sure if it will matter about the valve or w/e

 

The ISO Thermal Kit consist of the gaset for between the Lower Intake Manifold and Plenum (upper intake manifold) make sure you fallow the instructions and either WD-40 the Gasket or soak it in oil before installing (this will help seat the gasket and allow it to expand evenly in heat)... The Coolant Control Valve taps into the Coolant to Throttle Body Line before the throttle body. You'll install this valve and it'll probably remain CLOSED throughout the year.. The only time you would need this on would be the days you see ICE form on your roofs..

On Motordynes website it states the ISO will help reduce heat stroke...so wouldn't I want to install this then since it's always hot here?

If the gasket and CCV will not really do anyhing for me I have this hot/cold thing backwards I just plan to install the spacer and sell the other items to someone who could use them.

 

This is not correct. Its actually for any type of weather hot or cold, but the Copper version is better optimized for cold weather.

In any case the plenum will run cooler with it. And a cooler plenum is always helpfull for hot (or even cold) weather.

I'm curious though, where did you hear this or come to this conclusion? I ask because this often comes up on the discussion boards. Maybe I need to clairify the descriptions on the MD website?

Thanks,
Tony

 

Tony- Thanks for the clarification. I'm not sure why I got confused and this thead may have made it worse.

So...long story short, the ISO is benefical to us in warmer temps as it helps keep the plenum cool. And in colder weather (below 55) we simply open the CCV to keep things running as they should. Either way..hot or cold the ISO is more beneficial then just installing the spacer alone and the copper ISO is best suited for cold weather folks.

 

Correct, the Iso Thermal is good in hot or cold weather.

But, I am curious, there have been several people who thought the same thing you did. I wonder if its the way something is worded on the website that is confusing people.

Thanks for mentioning it here. I'll go over the descriptions again.

^ hey tony how r u doing =PP

 

Doing good and staying very busy.

BTW can you do carbonfiber? Pimp?

 

CCV is not as necessary, just leave it how it is stock or get the throttle body heater if you are worried about it.

It will void your warranty if you cut the coolant line.

 

Tony, it's typos and miss-reads... it happens all the time. I've seen people debate over things they have no personal knowledge of because they misinterpret what has been posted - or they miss-read it all together... often times people post quotes out of context and that perpetuates the misunderstandings... One small example is that your product prevents heat stroke (see post #5)… I know you are a brilliant engineer, but I thought MD was MotorDyne, not Medical Doctor … ha, ha – I realize that’s an extreme example but we all know the kooky things that go on out here and how **** gets misconstrued.

I believe your website explains everything very well… and the majority of post out here sum it up well… unfortunately there is no way to weed out the bad info – but most people that take the time to research should be able to find the correct info.

 

Why would you want a TB heater?... The CCV doesn’t heat it, it helps keep it cool... if you want to keep it stock the TB is already heated. As far as voiding the warranty – just install a new hose and there is no issue, they wouldn’t even know what you did. This mod has not voided any warranties that I am aware of and its on hundreds or thousands of Gs and Zs…

 

The Copper throttle body heater is advantageous in areas where it gets really cold.

1) You never have to switch it on or off depending on the weather conditions.
In places like Buffalo NY, where it gets really cold for most of the year, switching a valve under the hood, in the morning before going to work is the last thing anyone would want to do.


2) If a CCV is used, it must be turned on when it gets cold outside. And that means the whole plenum assembly will be heated rather than just the TB. And that means all the cold air inhaled by the engine is being warmed & expanded as it flows in. So in cold weather, the Copper TB heater makes more power and cooler air to the engine.

 

the guy is in TX and mentioned that his CCV would stay shut 97% of the time... I was asking slobo7x why he was suggesting the OP use the heater plate and implying there would be warranty issues using the CCV. In TX I would think the CCV would be the correct choice, and cutting the coolant line isn't (shouldn’t be) an issue
