Fitting a G50 in a bug chassis....

Haven't I seen this cab somewhere else Rich LoL

Very nice! That is becoming one very strong chassis.

Nice German Cabrio project!

Ricola,
What tires are you running on those wheels.
I have just picked up my wheels (same specs) and am wondering about your tire choice. Currently I have mounted up a setup of Pirelli Pzero Rosso 275/40/19 & 245/45/19 but they are feeling pretty "big". Your pics look a little more streamlined so I wonder about your setup. I was worried about how these would look being 19" rims but your images have confirmed that it will look just fine...

This car is coming together amazingly well, thanks for the great images and sharing the build with the world.

jmd, all specs are on my website for wheels/tyres as well as a hell of a lot more pics!

Here's last night's job:

Air filter intake...

Nice job! I like the widened fenders, and intake.

And a couple more...

I really like that solution!!! Well done Richard!

[ricola]

Thanks Wally, I was going for something like a Ruf intake...

Yeah, thats what it looked like to me and why it probably appealed to me as well

That opening there would probably work better than my current 'behind the car' air intake don't you think?
Will there be some sort of air box (where to put it) where you can locate the air filter?

[ricola]

Should work well, some guys in Australia have reported very good results from cold air intakes in the wing like this, boost coming on a few psi earlier at speed and really nice cool intake temps.
Other people have ducted to a sealed box around a cone filter but I will be building a panel filter airbox into the inner wing, hence why I needed to get my final choice of wheel in to see how much space I have.
I'll be fitting a mesh at the back of this short section of pipe to stop people/nature chucking stuff down it, my main problem to solve is to get a water drain in there somewhere without losing the ram-air pressure..

[Wally]

Thanks, good thinking!
Waterdrain hmmm, yeah, we don't want any water in the engine of course
Waterinjection would work though

Rich, I wouldn't have thought that a 6mm (1/4") drain would have caused a measureable loss in ram pressure. The ram pressure is a f(speed & air flow) and as the amount of lost air through the drain is directly proportional to the X-sectional area of the drain compared to the intake the loss will be very small. Besides, there will be a much greater loss as soon as you open the throttle!

You could of course work out the volume of air passing through the engine at the ram pressure and then through the drain at the same pressure to see the comparison

A couple of drain holes are my fall back solution, there is also the risk of them getting blocked by road dirt which leads to shielding them etc etc.. Not a big issue, just something I have to consider. Pressure drop wouldn't be as bad as a direct relationship, boundary layer effects on such a small holes would make the real pressure loss much less...

I have used this type of grommet to provide a drain that is less likely to block with road dirt from the wheels:
