Excerpt from post on RC Tech.net

Porsche Cup is a simple format for racing. A Tamiya F103GT kit ( or any 2WD 190mm chassis that can run touring car tires and rims ) and a 190mm HPI Porsche 911 body (#7335) with the Silver Can 540 Mabuchi motor. It's patterned off the real Porsche Carrera Cup series that offers a one-make series with serious performance.

What are the races like?
Two races. Starting order for Race #1 is the finishing order from previous round. Race #1 - 15 min "Sprint" race. Finishing order reverses the grid for Race #2 meaning race #1 winners will have to run from the back of the pack in the "Feature" or Race #2. The Feature race is 45 minutes long. Current batteries including the lipo's might make this distance if geared properly but a mandatory pitstop in the Feature Race forces all competitors to stop. Pitstops add to the excitement and open up chances to gain positions on the field.

How many cars can run a per race?
If you have AMB scoring and timing your software and system allows for 20 cars on the grid. Running 20 cars is non-stop action and a lot of fun. The series has points for all 20 cars on the grid.

What are the regulations on the chassis?
A Tamiya F103GT kit ( or any 2WD 190mm chassis that can run touring car tires and rims ) and a 190mm HPI Porsche 911 body (#7335) with the Silver Can 540 Mabuchi motor. Those who choose to run Lipo will add 4 ounces of ballast to the chassis to compensate weight differences between lipo and NiMH. BBS or spoked rims only (sorry, no dish rims in real racing... or you could sharpie spokes on the rims). Cars should appear scale in appearance to make the series attractive to the newcomer. We will provide a template to anyone to add number stickers in a very affordable way to each car. The kit motor (540 Mabuchi) is the series motor plus replacements are around $15.
