wow excellent thread and quite a digest for a night and a morning

a couple of ideas

1st idea reduce cd: flat bottom and dimple it like a golf ball used by VAG in most of their cars the dimple effect helps with air speed under the car

2nd idea: thermal wrap everything you won't believe the change it makes we did in our race car (a honda civic 1998) you reduce engine temps by A LOT and you increase exhaust velocity we used thermal tape in header and exhaust and intake to isolate it from heat and cold side radiator hoses to isolate them and everything we could keep cold to lower temps.

those are my 2 cents

love the rims, love all the effort you have put into this and I would love a pic of the truck hauling that baby if you have one.

sorry for my english not my first language

thanks for reading and commenting - your english is fine! headers are already wrapped... have started adding more thermal barriers in other places too for safety, but will put some more thought into what else can be done to optimize the engine... I've noticed that at the track I always run my fastest time during my second lap and times fall off by a tenth or so each subsequent lap... there is definitely a heat soak issue with the drivetrain or possibly the tires

the aero underneath the car is pretty bad, so I will be looking at ways to create a flatter profile... the dimpled surface under the car makes sense, I'll do some more research there
