Description

Important – To receive the maximum performance from your Offenhauser Turbo-Thrust manifold it is very important that you do not modify the top in any way.

Our reason for suggesting this is that after hundreds of hours of testing with many types of flow systems we finalized with the design that is incorporated in this unit. The center space bar is very important in this unit. The center space bar is very important to stabilize the internal flow of this manifold through all stage of R.P.M. To modify in any ways will definitely be detrimental to the efficiency of this engineered manifold throughout all R.PM. ranges.

PLEASE NOTE THAT THIS PART IS OUT OF PRODUCTION.
