Springless Wastegate

The Springless Wastegate is based on the ultra-successful DW1 wastegate and has been on race winning cars in RallyX and Rallying, as well as on some Pikes Peak single seaters.

Very similar to the DW1 wastegate in construction, the main difference is that there is no spring – the valve position is controlled by boost.

The main advantage is a significantly lower height, as the cap does not have to house a spring.

Designed to cope with the extreme conditions experienced during racing, the springless wastegate was designed with high performance and exceptional quality parts, so as not to compromise reliability:

  • Inconel casting
  • Nimonic 80 forged valve
  • Ti 6Al4V billet machined valve guide housing
  • Sintered valve guide
  • Internal Inconel heat shield to protect valve guide and membrane
  • Top-hat style Nomex-reinforced fluoropolymer rolling membrane
  • #3 JIC Boost connector and 1 breather fitting.
  • Can be supplied with a screened fitting as well, if required – this is an option.
  • V-band clamp mounting system, supplied with 304 stainless weld-on adaptors
