FINALLY....
one of the negatives to having an "in" at a race shop... sometimes when they have their own clients work... I wait....
If your eyes are real sharp you can see where the seat cutter contacted the chamber to provide enough clearance to add that top cut...
The good news... the intake side took its 3 angle quite well - 30 degree top cut, 45 seat cut, and radius throat cut.
The white arrows point out the area where the seat cutter came in contact with the chamber, I'll be blending these, and the area around the seat (green arrows) to get the best flow.
The less than perfect news... the exhaust seats didn't come out as nicely.
Do to the thin seat (OD to ID), and the new guide, the throat cut came out less than concentric... not perfect, but the remedy here is replacing the valve seats with a better(bigger OD to ID) seat - more material - so the throat cut can have as nice a concentric radius as the intake. This is a costly task and the benefit is minimal
The throat cut will work... and to prove it.... my client has requested me to get this on the flowbench... so next week I will have some flow #s!!
For the remainder of this week, I have blending to do.....
More to come.....
