How I check to make sur my 5/6 ports are opening past 3500 rpm's?

 

you could get someone to rev the engine past 3500 and sit there any watch them, I'm not sure if it needs to be under load or not.

 

That will not work. The engine needs to be under load.

Aux port testing: http://www.aaroncake.net/rx-7/6porttest.htm

This has also been covered about 100 times this month. A search for "port test" would have turned it up.

 

sorry, thanks tho.

 

if u have an s4 just put a dap of grease right on the rod at the actuator end. when they open the grease will move up the rod..

btw with my new racing beat header my ports open when the car is NOT under load...

I can rev it and watch them open from under the hood
