What water temp to run at?
Discussion
I should stop this reading bit... Have been looking tonight at this...

bottom of page 36 onto 37 its saying max power is produced at 75 deg c?.. it so I'm going to get MA to re-do my chip and lower my temps?......
What everyone else running??

Interesting.... Mark Adams will say 'run it as hot as you can' but then you read about bearing cap issues and the obviouse liner problems... I'm assuming he's doing this to get rid of things mixing with the oil like any un-burnt fuel etc.. but my oil gets changed every 2000 miles or so anyway so is it a problem??...
I may ask him to mod my chip to take it off fuel enrichment at 70 deg?..

Yes… I guess to can read a lot into scenarios without it actually happening… as you say a reported 85 or 90 deg water temp at the stat.. who knows what it will be at the mains or what the liner will see. I may bring it down a tad or run my 82 stat with 84 otter.. I know the fans will be on a lot but not sure I like seeing 90!
I want to clean the engine up this winter so will make these changes but I think one of the key areas to preserve bearings and may be even the crank on small journal motors is the have the thing internally balanced?... That way internal harmonics are not as lightly to start up and cause problems…

Have mailed Real Steel so see what they come back with... I'm with you.. it's amazing how detrimental frequancy vibration can be... When I worked in Aerospace we did a lot of work in this area (obviously).. and you can actualy drill holes using a solid piece of steel if subjected to the right frequancy.. so what indeed could it do to a crank....
Internal balance and a good damper as you say

Mmmm Sounds like your system as you say is reading a tad high... With an 82 stat on the motorway and a cold day you will probably find the stat starting to close to keep the engine temp up... so it’s strange you are seeing 88 deg.. I would have thought more like 78 / 80 deg?
The reason for not running the engine too hot is to stop expansion especially around the crank and mains. If blocks are not cross bolted you can have gaps opening up that allow the caps to move and in turn can wear out their locations and / or crack. also you can have liner problems the hotter you go also...
It's all in the balance as to what end you support... Hot runs the risk as above... but too cold messes the oil up which in turn can then be detrimental to your engines internals....
I guess there is no right answer but if you are actually running at the temps your stating, it may not over-heat, but I would be careful as to what else it could be doing internally...
