CT crossflow- manifold`s from England aren`t best maded rallyparts for SAAB. Casting is mostly porous and soft. Also adjustment between suctioncover and suctioncurves are mainly poor. To improve that, some welding and ”helicoil”- thread as well adjustment were necessary. Here hints how to do proper alignment.
Conc C/T manifold.
To be frankly this manifold is one of the worsed manufactured ever made to V4. We tested it early 1970 and it gavedlower hp then 2 staying carburettores. 2 of the over manifold have beeen made with smaller diameter and the flow in this manifold is terrible.
More they leaked a lot and had a very bad casting. My advise is to use something else. Sorry ;-)
You are right Rolf. I like to tested it in any way because I have good memories of CT manifold (except poor casting quality). I also think It will be much better for 1,6 liter Saab V4 than Saab´s original Cross Flow because of shorter canals to the sylinder. Let see how the engine will work
