Hi Paul,

Great looking piece of kit that you have developed, I have a 13BTT REW
Series 6 racecar, these may well be what we need to reach higher revs, with
factory manifolds power begins to drop off at around 7000-7300rpm.

Does the lower manifold flange suit these 13BTT rew engines, obviously
drilled to suit as required, wondering more about port alignment etc.

Cheers,

Mark

We don't make that stuff anymore. We are now focused on P-ports only.
