Groundzero intake port measurements
Groundzero intake port measurements
I did some measuring up against a stock lower and here's what I came up with:
The stock secondary ports are 1.490" in diameter. There is a chamfered edge at the top, so the port is actually smaller than it looks from the top. I took the measurements down past the chamfer about half an inch into the port.
The Groundzero intake's secondary port is 1.55" in diameter, no chamfered edge.
Same chamfered edge in the primary. Stock is 1.170", Ground zero is 1.210"
Just thought I would share that with you guys.
There is plenty of metal there to extrude/hone.

Maybe you could get your hands on a RE manifold to compare?
