I run a water methanol mix of 50/50 on the RX-7. It comes on at 13psi and you can watch intake temps plummet.

 

It took a while to get my Aeroquip fittings for the valve setup but they finally arrived and now the killer chiller is fully installed.

This first picture is of the drag valve. I will insulate it after i know for sure it doesn't leak.






This is the kc valve that allows you to shut off the kc and have 100 percent in cabin ac.



All installed






Next up is finishing the wiring.

 

They bolted up super easy no rubbing at all. Absolutely perfect clearence. Just disconnect the steering shaft.

I also wrapped them up in a dry bag to protect them during the installation and keep them mint.

 

Always the same, one is better than the other with no reasons given why. I have had a KC for 5 years now on my SL55, I am happy with it.

 

Ok guys a quick update on the project:

The engine bay is done and all mods fit perfectly




The 3way valve is installed and plumbed up




I reused the factory headlight sprayer routing and mounts for the valve wiring harness






These Duetch connectors are fantastic. Ive used them on past projects and are very durable, high quality and water tight.




I also ended up moving the horn to the drivers side on order to make room for the KC valve



Next task will be running water lines to the trunk and wiring up the pump.

 

You will love this setup and wonder why people keep adding more and more larger HE or for ugly top mount IC.

 

The water lines are now routed and mounted in place.

A few pics of the lines from front to back:

From the 3 way valve under the passenger front



Over the passenger fender liner


By the washer tank into 90 degree high flow bends then under the floor panel


used the exhaust hanger and a rivet nut to bolt on a hose routing clamp. This keeps the hose well away from the half shaft


Very carefully cut two holes in the single wall section of the trunk floorboard. Used touchup paint on the raw metal to prevent corrosion before installing gromets






Next up is finishing up a bit of wiring and then testing everything out and checking for leaks ect.

 

Nice job on the routing. Looks great!

 

It's been about five months since ive driven the 55 so im looking forward to crusing her this weekend.

The trunk tank reminds me of a flux capacitor now that it's installed and running.

 

Everything is installed and running well at this point.

After a half hour of idling the rear tank temp was 44 degrees Fahrenheit and still falling. Very impressed with this new killer chiller "race" setup.

I need to load up the new tune and then ill do a few wot pulls to see how she runs.

Part two

 

Watched the vids. What part of NC? I’m in SC.

Owned since 2008? Wow, your car is super clean. Love it.

Would like to do the KC one day also like you did your install. Clean and hidden, nice!

Exhaust is like mine. Love the sound it has while normal driving and plenty at WOT.

 

Thanks bud!

I'm in the RDU area.

 

I’m just more curious about the light in the tank bc I want to put a light in mine. Running out of new things to do so 🤷🏻‍♂️

These guys are great to work with. I used orings and a light layer of marine sealer to sandwich mount mine. The idea worked great and was courtesy of Beaux at boatpluglight.com.
