I ask this plenum system them for last year (2006)Wotland wrote:Hi There,
May be something more suitable for your application. Triumph Rover Spares (Londsale - Australia) offers an twin 57mm throttle bodies converstion for $775AUD. This kit is based on Jenvey throttle body.
Cheer.
They say that this kit is not longer available. Because power output is "almoust" same/identical that 72mm single plenum. But doing this twin plenum is mutc more expensive that ported single plenum.
