What header tanks are you LET boys running?? I have the standard one on mine, trouble is the filler cap doesn't seal very well, so when the pressure builds up high the header tank lets out air and doesn't pressurise. So if I stop after a hard run the coolant has started boiling.
Also I noticed (don't know if its related to the coolant boiling) but my header tank is splitting on the seam.
What are other peoples experiences/ideas?
For peeps who run digi dashes, how many bars do urs sit on? Mine is 3, is this right?
