Cooling above 90 degree ambient

Thanks for all the replys guys. 

I have contacted Jon at PE to ask if they do a compensator for the 230F gauge.

Marlin are you saying replace the stock WP pulley with the OD unit from someone like Ipsco.  I have the Flowcooler water pump fitted and there was a new core fitted in the rad last year.

I have bled the coolant system several times as you describe, doubt there is any air in the system now  though I am going to give the vacuum system a try now I have bought it.

No the system is not overheating but I would prefer all the gauges including the temp to give accurate readings.

Marlin, I forgot to mention I do have the Sacc reduction pulley on there as well. I've had it for a while that's why I beginning to believe I didnt have the car high enough to bleed the block properly.  

I now have a pressurization tool as well, will try it the next time.

FYI; the SACC water pump pulley is an overdrive pulley.

For those people who now have a vacuum filling device; it's not a bad idea to pull a vacuum in your cooling system, then leave it like that for a few hours before you fill the system with coolant. If the vacuum drops, you have an improper seal somewhere. It might be so minor that it probably wouldn't leak coolant but it's still worth investigating.   

...Yes! You Do Want to  Use The Little Pulley!  BUT!! This 4.9" Diameter Pulley OVER-DRIVES the WP RPM by 11%...How is THAT a 'Reduction'?? Oh, By the Way...NO Teflon Tape or Sealer on the Sender Threads, It Can Mess with the Grounding.
