Ok simple one really but I don't know the answer lol.
As above really, how much heat soak is too much?

I'm running a charge cooler set up, when driving around and also when stationery the charge temps hover between 7-10 degrees above ambient. When I say charge temp I am reffering to the temp measured after the charge cooler.

However when the vehicle is stopped for a short while the charge cooler isn't doing anything so I suffer some heat soak where the charge temps are rising to around 20 degrees above ambient, is 20 degrees above ambient anything to worry about?
Cheers Ian.

 

Interesting as your charge cooler us less efficeint than my intercooler as i see ambient or 1 at most 2 degrees above ambient.(top mount) although when stationary mine can really climb to 40,50 and once or twice 70 degrees. As long as you dont hammer it straight away the temps should come down pretty quickly once on the move

 

That's good to know then I'll keep my eyes on the temps then.
As for being less efficient I didn't expect the original legacy cooler I am using to be all that good lol.
