Ginetta G56 GT4 Intake Restrictors

We developed these intake restrictors to allow our Ginetta G56 GT4s to compete in World Racing League’s GTO class. Since this is a power to weight based racing class, we are often adjusting our pwr/wt setup to suit a particular class.  Adding weight and power for tracks like Road America and reducing both for tracks like Mid-Ohio.

The G56 GT4 is a Chevrolet LS3 powered car, using a MoTeC M1 with MAP sensors to calculate fuel. Ginetta offers a small selection of intake restrictors, but they are often too large for use in WRL (or NASA’s ST classes.)

Our restrictors are custom machined from billet 6061-T6 aluminum to exacting proportions and include a new silicone o-ring for installation (upgrade from the OE buna rubber o-ring). Restrictors are electric pencil etched with their ID for easy identification.

The MSW Ginetta intake restrictors are externally the same exact dimensions as the genuine Ginetta part and install in the same manner.

These are a made-to-order items due to the variety of sizing available.  Plan on 3-4 weeks from time of order to shipping.
