Overheating and Detonation Warning Sighs

WHOA who told you 1 bar? definately not, you will pop out your crank seals. very neat tester you built, remember to spray soapy water all over it as well if you find your motor doesnt hold air. I used a pool filter gauge as I couldnt find anything which had incrememnts small enough to show 0.4 bar
 
Ok will have to get a different gauge then cause my one go's up to 10bar and I don't think I will be able to read what I need on there. I went back and checked what the guy wrote, I miss read he said your gauge should read up to a 1bar. My bad. :-[ Thanks for the info guys! I:I
 
ha the pool gauge was the cheapest and best i could find. R80 from the pool shop :) as opposed to something R400 from the engineering suppliers.
