180hp 1.8t in Bug

[volkdent]

I ordered a new radiator yesterday. The old one had suffered too much at the hands of vicious pavement, and finally the leaking would not self repair. The new one will be 3" wider and about 1" shorter, so I'll gain and inch of clearance. I'll also be fabricating a sort of cage to protect it from future damage and finally get on to making the duct system to feed it air, although so far airflow hasn't seemed to be an issue.

Yep, after your tales of temperature, I was a little worried. I have to tell you though, I suspect an air bubble is the culprit in more situations that airflow or water volume or radiator size. I had originally bled the air with the car just sitting. After I hit a few things, I was losing coolant rapidly so I was adding on the fly and BLEEDING on the fly, engine running. Bubbles were all over the system. Once I just let it sit there for a bit then bled it, no troubles at all. I couldn't keep the temps right before I bled it properly, it was always running a little hot, but not too hot, once the bubble were gone, perfection!

I just hope the new one will be able to cope with 300hp...
