Re: Metro modprod hillclimb/sprint VVC/6R4-ish thing...
Neither a Metro bonnet nor a 6R4 bonnet fit this car, so we made our own out of alloy. It includes the necessary bulge to cover the cam cover, and a set of rear holes allowing the high pressure air generated by the spinning tyres and the cooling system air flow to join the boundary layer flow over the windscreen where it ought to assist with the flow over the rear wing. Another future task is to get a single piece front end made up.

It's first hillclimb?
Raised up to let us fit the front undertray.

Well, it is not too difficult to make it ground effect. Being a road car, you could even fit side skirts, which are outlawed for track use. Getting the floor something like flat will be the biggest challenge.

hmm didint really want to fit sideskirts but surely if I just stick a sheet of Ali underneath and heat wrap the entire exhaust should be flat enough it's just the front undertray and diffuser I may have issues with

The front undertray doesn't need to be complicated, but you will have to work around the exhaust and the gear linkages. The rear diffuser will clash with the spare wheel well but you will just need to get the best length possible. You should aim for a diffuser angle of 7-8 degrees. You will also have to work round the silencer, which might need routed straight out the back if possible.

cheers bud I'll have a think about that at the front then so by the sound of it it's easier just to cut the wheel well out then? and just make sure the diffuser is as long as I can get it?

besides helping aerodynamics an engine bay undertray should also lower the engine noise in car.

very impressive build! how long time have it taken to get this far then?
the tubing on those rear trailing arms looks a bit thin to me, what do you think, did you do calculations on that material also?
the works turbos definitely used a lot larger diameter tube.
