What is a Plenum Chamber?
Turbochargers deliver air at a relatively constant rate, while cylinders demand it in a varying manner, as the valves open and as piston speed varies through the stroke. Simple direct ducting would give problems where the nearest cylinders received more airflow. The pulsating demand from the cylinders would also show problems of either pressure waves in the duct, or a shortage of inlet air towards the end of the inlet phase.
The solution is to provide a large-volume plenum chamber between the inlet and the cylinders. This has two benefits: it evens out the difference in path restriction between cylinders (distribution across space), secondly it provides a large-volume buffer against pressure changes (distribution over time).
Custom Billet Plenums
While we don't make full turbo kits for many bikes we have turbocharged quite a few different models & therefore have made custom billet plenums to suit certain bikes.
We can replicate these as required. (Please note these are made to order & can take 2-3 weeks for production)
This model is for the Suzuki GSX1400.
Modifications to the design for placement of inlet or BOV can be made as requested.
We can also supply it with a Turbosmart Blow off valve (BOV) pre fitted.
