is efr IWG or EWG?

 

Ive heard about waterless coolant. I don't doubt its pros however I am just a chicken switching over something new.

I have the IWG

Howard, appreciate the breakdown. I'm sure either my IAT calibration is off. I purchased a fast reacting IAT years ago details of which I don't recall.

Very interesting to see my peak tq occurring at such a low RPM. Aside from my IC design or overlooked boost leaks I don't see anything else being the root cause...yet. I will dig into it.

 

Happy to chat with you live about Evans NPG+ and why I love it

Shoot me a PM if interested, it's an easy conversion and IMO you won't regret it

 

me too, despite some rotary pros telling me not to bother

shutting the car off after a hot lap with absolutely zero boil-over on otherwise OE housings (coolant passages not machined/grooved) was enough for me, though imo it has additional advantages

getting any previous water out to the appropriate amount is a pitb and added cost though if it’s ever had any water in it prior or needs to be added in an emergency situation.
