long story short...

Besides a very cool machining into your manifold 16% greater flow to the combustion chamber from the turbo. The mod is not the best first mod but is more a stage II mod in preparation of a bigger turbo. Actual VAG readings will be forthcoming and it will be dynoed as well to document the HP improvements.

The retail cost is around 1,500 for both the manifold and throttle body work. Although a group buy could well be arranged. The manifold by itself is about 800.

Re: 16% greater flow to the combustion chamber from the turbo
Not exactly, 16% greater from the entrance of the intake manifold to the exit of the manifold, with a similar gain on throttle body.

Increase is less.
Take a 1/2" garden hose and measure the flow rate, then take same length 5/8" hose and measure. 5/8" will flow more. Compare flow increase. Now add 1/2" hose to it and measure, flow rate will be less than either alone. Then measure 2 lengths of 1/2" hose flow will be even lower. Compare flow increase. Increase when going from 1/2 + 1/2 to 5/8 + 1/2 will be less than increase from 1/2 to 5/8.
No change from turbo to throttle body and no change from manifold outlet to combustion chamber. So increase is less than 16%. Data so far shows 10% increase including other mods.

It might be a bad influence on me
