How thick is the aluminum after market intake? I want to drill and tap it. Is there enough meat to hold a 1/8th pipe tap? Im looking at installing a vacuum gage so to be able to more precisely adjust the timing going down the road and also to watch the intake valves.
It's probably thick enough. All you need is 2 or 3 threads worth.
How about this?
And when you're through with the vacuum gauge you can use the tap for your Wolf Whistle.
Yes, No problem, you know not to tap too deep with pipe taps
can you explain to the uneducated (such as myself) how looking at a vacuum gauge going down the road will help adjust timing?
Nathen, The higher the vacuum the more efficient the engine is running.
no need to drill the manifold
