No, acutally I didn't know about not being able to use Mugen cap...thanks, good to know. And with the EMS the "stock" temp guage doesn't work, as you know. So I have the modifry fix for that and I'll get up to 5 bars and a CEL coming in and out and will get steady over time durring a 20min HPDE event at about 90 degrees outside. At about 80, with the heater running full blast I'll typically stick to 4 bars for most of the session, bumping up into 5 occasionally.

4 bars = 205
5 bars = 220
6 bars = 235
CEL = 220

So basically the car isn't getting THAT hot...I mean I've NEVER seen 6 bars, and 6 bars on my guage would be 4 bars when using the stock ECU (obviously I'm talking AP1) but anyway, I'd feel more comfortable not having to run my heater at all and being able to stay in 20min in 90 degree temps without an issue...so Koyo here I come.

I'm also out braking the stock pads now too. In one weekend I went from BRAND NEW rear pads to COMPLETELY GONE rear pads.

Most companies come with two types of radiator caps (ex. spoon). OEM style radiator caps do not fit the koyo, but the other type should fit.

Redline's water wetter is added to coolant to increase heat transfer in and out of the coolant. It works by reducing the surface tension of the water. This allows the water to be exposed to more surface area in the engine and radiator.

I think my S is pretty much operating at 5 bars all the time (once warmed-up of course). Not entirely sure--I'll have to count next time.

Dayum--you went through a brand new set of stock pads in one event? That is crazy!

Well, ya the AP1's though only have a total of 6 bars available to show...the AP2's have 19.

With where my temps are getting to, it would be like a stock AP2 showing 9 bars...under normal driving you should show 8.

Spoon lists two types of radiator caps. Type D and Type F.




Type D fits the OEM radiator.
Type F is the same style as the Blitz Type 1 Radiator cap I believe you are using on your Koyo.

Both Mugen and J's racing also list two types of radiator caps. One that fits the OEM radiator and another that is most likely similar the Spoon Type F/Blitz Type 1 radiator cap that should fit your koyo.

Im just trying to be nice and help you out.
