I'm after some informed knowledge of how to lower the temptemperature under my hood.my car is a clio 197 turbo .
I have read all about bonnet vents only working when stationary due to air pressure over bonnet being greater than that trying to raise up and out of vents . Has anyone tried a turbo jacket? Should I wrap the manifold down pipe ? I have heard it may crack
The car has working air extractors on back edge of front wings but not efficient enough.
I know now the air filter is in the wrong place as when the rad. Fan cuts in hot air blows directly on to it .I understand how hot the turbo runs at so the effect to inlet charge may be minimal..or not?. The intercooler is 90mm thick so as big as I can get .
The management system will knock back timing and boost if inlet temps are to high and this I feel after a hard run
Any ideas welcome
