Since there has been much a do about all the BA boys getting claimed improvements on crispness using a colder thermostat I went to Coventry and got a 160 degree replacement for the standard 190.5 degree item.
I will let you know if I notice any improvement at all. I figured it was due for a flush anyway.

UPDATE

Did couple hundred K's in it some of it under load. It does run a little cooler and seems maybe a smidgen crisper but the temp guage shows it to be still within the designated "normal" range albeit in the bottom of thaty range.

Cant wait to see how this one turns out.......

Running a colder thermostat causes more engine wear as the engine won't reach its intended operating temp. Also causes your oil sludge up. But what would I know!

Everyone has an opinion, the guys I checked with say 160 degrees is enough that engine wear would not be a factor however it may affect engine management slightly with enrichment. I would tend to agree with the engine wear as it is the same temp as I ran from the start when I rebuilt my cleveland and when I changed the heads for alloys at 160000 K on the engine the bores still had honing marks on them. Besides if the engine still gets hot enough that I can't leave my hand on it without getting burnt then I'll take that to the bank and keep my fingers crossed the worse that could happen is that in a few years it may force me to rebuild it bigger and better. He also recommended that I stay with oils no higher than 10 - 40. Time will be the test we will have to see.

Well done champ. Can't wait for your results, as this would be the same thermostat for all AU V8's im guessing?

Cheap kW are good kW.

Remember when you start chasing the high end kW they cost a lot more! any kW for small $$ is a good thing (tm)

good call, might make it a nicer deal all over....

Well in the other thread apparantly it's not the 3kw that you may make on the dyno it's the extra torque that you feel while driving it all the time? And for 70bucks it's almost cheaper than getting a genuine thermostat!
