Thank you Andy. That was very helpful.andybond wrote: ↑Fri Jul 17, 2020 1:52 pm From my research there are a couple of reasons for heat soak.
1 ) Location of the actual air to air intercooler. Its directly above the block which has limited airflow so naturally the heat rises and dissipates some of its energy into the A/A intercooler
2 ) The supercharger is running towards the upper limits of the design for the MP62 anyway so generates a lot of heat for the A/A intercooler to dissipate, but
3) The actual mohawk or even the smaller air ducts on the top of the roof are not very efficient due to size and location. The radiator exhausts are releasing warm air into the intake tract for the intercooler hence not cooling as well as it could.
There are some solutions
1 ) A better core with some cooling ducts as seen with the pro alloy kit
2 ) Chargecooling.
You will note the shortcomings when pressing on and then stopping in traffic and sustained WOT on tracks. For general road use I would wager that you will find it hard to notice any degredation. This is more due to the fact that its a gradual change rather than a somewhat digital change..
I did suspect that the longer roof scoop may suck up the hot air 'better' than the shorter scoop.
Oh, well....more things to investigate, but now I really need #138 in my possession, and to drive it, before thinking any further.
This is probably the only time in my car-owning history that I know more about a car than how it actually drives!
