However, I prefer an independant gauge EGT for reading that stuff.

I got a curious question, that I don't know if was asked about this mod from before... Could I go back to stock relays in case of one of those relay's going out? I mean if that happened, my car wouldn't have any problem running on the stock relays with the aftermarket modification on would it?
I'm not really afraid of this happening, I guess I really just don't understand how that metal L placed in the coolant line relates straight to the fuse... Does it just have some temp. sensor?

no tools required... i had mine in and out several times while testing the product...

Generally, though it is better for power, an engine that runs cooler, runs dirtier.
203°F coolant temps would probably yield the cleanest exhaust.
The CAT temp wanders back and forth depending on load. It can be anywhere from 1100°F to 2000°F and still be in nominal operating range (with different life expectancies, of course).

Higher Coolant temps equal more complete combusion of the fuel (especially under heavy load) and it also serves to keep the cats at the minimum operating temp.

This mod looks the equal of any Cold Air Intake mods and is cheaper.
I would like to see if there is any HP increases with this mod. Anybody???
I know there should be an HP increase, but I'm curious on how much. If the mod can show a confirmed 3 HP or more, it would just put it in a stronger position against the CAI mods ( AEM and Mazdaspeed CAI would be good to compare to) and may make itself one of the 1st mods an RX-8 owner should do.

This MOD was not designed to be a HP increase! It will let your engine run cooler in extreme temps much longer than the factory setup! Fans will come on alot sooner= lower temps.
How can you notice a 3 HP gain anyway?

Reported Side Effects:
1. Better starting after short-term parking.
2. More consistent idle due to higher compression and lower heat soak levels.
3. Better low rpm throttle response and horsepower increase due to higher engine compression.
4. Colder air-conditioning temperatures.
3 HP is an arbitrary number that I used, interested if anybody tried to see if there was a little HP increase.

it does what it says it does... keeps coolant temps down...

Just installed this mod. Extremely simple, installed in like 20 minutes taking my time and not trying to rush anything. Going at a fast pace it could probably be done in about 10 minutes.

Well heck I was eyeballing this piece but I still dont know if the new flash changes the fan's activation. Plus the weather is a little cooler here in Ga--mostly in the 80's. Funny how 10 degrees F will make such a change in the car. Big differance between 85 and 95 ambient temps.

it makes sense for this mod to increase hp... I doubt that it would be enough for a dyno test to reassuringly notice, but I'm sure in some sense it does increase it in some respect. If the whole engine bay is cooled by some 10-20 degrees then wouldn't the air going into the engine have less heat to deal with? In turn allowing more condensed air to enter into the engine?
Wouldn't it be like the difference of dynoing a rotary in 70 degree weather compared to 90 degree weather? Are any changes even temperature even noticable under the hood?
None the less I didn't buy this modification for hp reasons, I mostly bought it for A/C reasons... Before I bought this my A/C was questionable at 90-100 degrees outside... Now it is cold and only that!

Although this product is not marketed as a horsepower upgrade here are some real world dyno results. The thumbnail below is an automatic trans. Interceptor-X tuning session from ~2 weeks ago.
During this session all the runs were started only when water temp dropped to 82c. At the end of the session I suggested we install the cooling fan control kit and do another pull, nothing else.
Without the cooling fan control kit the Interceptor-X temp. gauge would consistantly rise to 94c and the majority of the time flash 98c by the end of the run. With the kit installed the highest water temp. was 88c. Just goes to show you a cooler running rotary engine will make more power!

My understanding is that the RB reflash does something very similar to this Mod, but this mod is permanent and will not be lost due to any future factory reflashes like to RB flash will.

It should say "Free's up HP lost do to heat" instead of "horsepower increase".
Your not really increasing HP considering the car would have the same "increased hp" value when it was cold.

well then wouldnt it work better since the rb will allow only 1 fan at a time..

Brillo has had the RB flash. He's had the Interceptor installed although he removes it so much for testing purposes on other things it's like a change of underwear. He also has Scott's mod. His car cools best with Scott's mod. We've taken the car out under different circumstances to test that specifically. That should take care of that question.
