3 Lug ALS valve
3 Lug ALS valve
The 3 Lug ALS valve was originally designed in 2011 and has been on race and championship winning cars in RallyX, WTCC, WRC and others.
Featuring a 33.75mm (1.3287”) outlet port, air from the plenum or compressor (depending on the plumbing used on your engine) is fed into the primaries through 4 tubes with a bore of 12.70mm (0.500”).
Cold air is fed into the ALS through a Wiggins style aluminium fitting with a bore of 23.00mm (0.905”).
Designed to cope with the extreme conditions experienced during racing, the 3 Lug ALS Valve was designed with high performance and exceptional quality parts, so as not to compromise reliability:
- Stainless steel casting
- Steel 214N forged valve
- Austenitic Stainless Steel spring - this is available in many different spring rates, depending on your boost requirement.
- Aluminium billet machined valve guide housing
- Colsibro valve guide
- Viton Quad Ring seal to valve stem
- Top-hat style Nomex-reinforced fluoropolymer rolling membrane
- #2 JIC Boost connectors – different colours to ensure reliability of plumbing
- 3 Lug plate mounting system, supplied plate (stainless steel) and inlet air (Aluminium 6082 T6) adaptors
