Adjustable thermostat
OK this is not completely my idea: it's just an improvement of what I saw here ZR-1 Forum
I'm not debating about the optimal engine temperature, I just wanted a lower 'stat.
Here what Hypertech sent me: a so called 180F.
The lower temperature I saw in winter has been 195F (WTF!), so I decided to make a little modification...
The housing has a 4M thread exactly in the middle of the seat for the wax motor.
With an external screw it is possible to adjust the opening temperature almost on the fly: just replace the screw with a longer or shorter one, depending on your needs (do it when the engine is COLD!)
It's important to put a seal betwee screw and housing, also the housing has to be flatten around the hole to accomodate the seal.
It's better to lubricate the thread with some anti-seize.
The point of the screw should be flatten for fine adjustments.
The crappy Hypertech 'stat doesn't closes copletely (metal-to-metal seal) and it's a real pain to set the desired temperature. At the end I decided to modify the stock 'stat which has a rubber seal - much much better!
