Building a racecar

[dugmar]

I've been photographing various stages of our BMW M3 racecar.
This is how it looked when we got it from BMW. A bare shell...

I'll post more as the car progresses and photos are "cleared." Can't give away too may secrets to the competition. :)

Does the shell and chassis come in like that from BMW? I see its got suspension fitted, What else comes with it? Does the engine have to be the original?

Does the engine have to be the original?It comes from BMW Motorsport with a rollcage, that is it. It comes with no suspension at all. The chassis is also modified / reinforced for racing in certain spots. The sheet metal is identical to the street car. We threw a stock M3 suspension in it and some random wheels/tires on it just so we could roll it around the shop.

In our series it has to run the original engine, yes.

Thanks Doug, what sort of engine mods are you allowed & what kind of power:weight ratio do you end up with?

Interesting Stuff, Thanks :thumb

Engine mods are basically not allowed. That engine stock makes 333HP, but we should be making more than that since we can run different electronic management which lets us fine tune it quite a bit. The final power numbers won't be known until the car is on the dyno. The car can weigh no less than 2950 LBS, according to the rules.

Brakes & Suspension are in...

Sorry about all the questions Doug, but what's that in the right hand corner of the boot (trunk), a dry sump tank??

That is exactly right, it is a dry sump.
