yeah, the car ran considerable cooler before the nose went on, the the radiator is clean.. its surly a air flow issue.. barely anything is getting the the radiator.. I consider that a good thing at this point considering the underbelly of the nose is not on, it's directing air where it should quite well, around and over the car..
My hood lift should correct the air flow issue and if not a larger lower spoiler than the stock one should totally correct it.
As for where the cars pulling cabin air,, its still a total mystery to me.. cant see it getting much air from the cowl thats totally sealed .. watching bugs flow over the hood and wind shield there fly right over that are very smoothly.
Now I'm on to designing the tail.. so far its quite extreme to lessen the wake..
