Description

A flawless reproduction of the 1974 RSR slide valve induction system. Fits all classic 911s.

This German-made system has several improvements over the original factory parts, including higher quality bearings and tolerances.

The slide throttle intake system is track-proven and requires little maintenance, nowhere near as prone to the sticking throttle issues of the original parts. This system is run by both EB Motorsport FIA Masters Hsistoric cars, and also the Glenn Janssens’ Belgian Historic Rally Championship-winning 911 with sealed and FIA inspected engine.

The standard system has 46mm bores, but can be supplied with other sizes on request, to suit engines including 2.3, 2.8, 3.0 and above.

Remember: these throttles produce winning power on fully legal, FIA-sealed engines in Masters Historic, and in open regs engines as per Belgian rules. They are proven to work, and to win!
