Yes, there’s a permanent in-ground high performance dyno located in downtown Pottstown year round! And thanks to their kind owners, there are special deals for dyno pulls during L’oe Show weekend, adnd now there’s even 2 show awards available for VW Group cars to have some fun competing for.
Miller Mountain High Performance is a brick and mortor performance shop located on Pottstown High Street, in the heart of the show weekend,. Their permanently installed Dynojet 2 wheel drive dyno is available throughout the show, with their permanent and weekend leaderboards.

For 2025, we will have be giving two of our German Gewurz Ketchup trophies to owners who take their cars for pulls – highest horsepower by a VW Group Engine (yes, if it’s swapped into something else, that’s okay, but a Hemi V8 in a VW Beetle doesn’t qualify, sorry…), and Miller Mountain’s personal choice (we’re all hoping it’s a Rabbit with a 1.6L diesel, or some Bosch CIS injection fuelled turbo something from the 1980s).
You can book your dyno pulls by calling ahead, or visting the shop:
