|This is the exhaust manifold. The holes are matched with the exhaust gasket. The holes from the exhaust manifold are a tiny little bigger then the holes of the exhaust runners in the head. This is made in a way that the air stream does not "bump" somewhere as soon as the air is entering the exhaust manifold.|
|Pic from the exhaust runners/ports in the head.|
|Pic from the intake runners. These are matched with the T-Vis and the T-Vis is matched with the gasket and head. Lots of work, gasket needed to be modified too, due to the intake ports from the head were to large.|
|Close up from the intake runners.|
I kept the T-Vis. In my opinion, the T-Vis is usefull for daily driving. Dyno tests have proven this. And almost all new engines designed lately are having intake runners with adjustable lenghts, special made for drive ability. So I kept it!
The T-Vis is matched with the gaskets, and the middle 'bridge' is 'knive edged'.
|Close up of the T-Vis. The T-Vis plates are matched in movement (open/close). Due to time maybe, the left two were not synchron with the right two. That was fixed.|
