Hi
At the suggestion of Ricola I fitted another tap in the intercooler plumbing to close of the H, so when not in ice cooling mode all of the water goes to the front cooler.
All this go faster stuff is making me think about a brake upgrade.
I have 996 rears on the front with 930 rotors which work really well.
I saw some Boxster fronts on eBay and got them at really good price, just sourcing some rotors now.
Bought some more parts for my brake upgrade, some 944 hubs, thanks to Wayne Penrose for these and I bought some DBA Boxster front rotors from Tyler at 999 Automotive.
