Plus finally sorted a good spot for the front tow strap that's not going to rip off the IC piping

Looks ace Ant.
Now you just need to get some flat underbody protection to stop the turbulent air under the car.

Thanks Clay! Yes, not looking forward to sorting that out

Thanks for your thoughts on the balance / weighting, had a play raising the passenger side (1 1/3 turns on the KW's) away from symmetrical to up the load. Already noticed an improvement (less likely to chirp in 1st when the boost kicks in), or so some quick testing helped me believe.

I'm still trying to understand how the swaybar and chassis will work with an uneven balance, but how one defines 'even' when the car is not symmetrical in weight or construction, its better left to trial / error to see. I know Buller Scott was playing with the weighting balance and ended up with some odd heights going on to get it close to balanced in the TDI.

Mate, no worries. I'm glad someone found it useful!

I think we're on the right track however without the proper scales we are just going on feel and unproved theories.

I love to play, I'm almost embarrassed I hadn't thought of playing around with it myself. The car feels less bumpy on the road as well, having the passenger side higher is definitely a more balanced position.
Would someone with stock suspension care to measure the front arch gaps? I'm thinking the passenger side is a little higher in stock form.

Corner weights are the only way to sort ride height. A datum is what you need, you can fiddle to your hearts content afterwards. Surely you guys can find someone locally with some decent corner scales? I'd hit up some local club race, hill climb clubs and ask around. At worst you could roll up to a v8 garage and offer to swap the apprentice a carton of beer for his time to weigh your car while you adjust corner weights with ride height.

Fred Puhn wrote an excellent basics manual on developing stock suspension. Extract here on the topic.

That new splitter looks the part, us like you said it'll hopefully benefit you too on track. I'd be interested in the other, but I'm in the UK haha!

**noone** · 15-07-2013, 04:56 PM

Yeah, I want it as well, trying not to spend more coin on the Polo...

So been a little while but still having fun in the background

First track outing yesterday since the new snail went in and had the pleasure of lapping with some Euro royalty

Really happy with all the new power available but can see some wider and more track orientated tyres are becoming more of a must. Along with sorting the front end aero.

So giving the aero focus a rest for a bit I'm now back to airflow and cooling. Had my turbo charge pipe ceramic coated first

Massive thanks to Paul at Thermal Edge Coatings in Brendale for his support. Great guy to chat with and puts his money where his mouth is when it comes to knowing his product. He currently owns a sprint car and races it himself in top level National Sprint Cars and is now trying his hand at the insane national sprint boat comp. All his race vehicles have his very own thermal coatings which is also the same as his customers get. Can't recommend them enough.

Then added some more gauges to the mix

EGT

Air Fuel

Little dash storage tray came in handy with the help of a drill

And finally in after some much needed ale assistance (not a fan of electrics)

Unfortunately the EGT probe won't be sorted until the engine build but the air fuel should be up and running very soon.

And back to the track - well winter has finally hit with a nice ambient for the session (sorry bit blurry 12.1*C)

So mounted the probe as close to turbo as possible to see what sort of bay temps I'm dealing with and to compare after I bang the new bonnet vents in. Also the carbon sheet I had in mind to cover the grills on the top of the bumper is proving hard to cut on an angle, so some tape took its place nicely

And to my surprise here is the result

Pretty sure there's not too many cars that will allow you to do this after a 30 minute fang around a circuit

Barely warm

Anyway on the airflow side 6" stack arrived

Just waiting on the new filter, 6th week now
