Speed Density High-Flow Intake Setup OK guys, I need some advice here...
My car is tuned in speed density and has the LS1 PCM. It is a ram air WS6 with a K&N filter and still has the stock MAF on it. The baffles have NOT been cut out of the hood.
My car is making good power to over 7400rpm. I want to make sure I am getting everything I can out of the intake setup. I have a feeling that my current intake setup is a restriction, and I also want to remove the MAF becasue it isnt being used.
What kind of high flow setup should I look into? How effective would cutting the baffles out of the hood be and making a one piece coupler from the throttle body to the airbox be?
Thanks

No restriction, baffles, or turns. Of course it wont be worth anything without following the path upstream - TB, Elbow, Manifold, and Heads all have to be high flowing and spinning a lot of revs for that setup to make a gain.
Do your MAP readings support your suspicion of restriction???
You could put a small piece of PVC or pipe in place of the MAF as a cheap simple test.
FWIW I also believe that the MAP location coupled with large TBs and moving some air results in a Bernoulli effect causing some reading of vacuum when there really is none.This is based on being around some cars that saw "MAP restriction" with a 58mm and the same restriction with a monoblade.

It's not a cheap setup, but on my build I will be running the following intake setup:
-MAFless SD Tune
-Fast Toys 104mm lid
-Chris1313 Ram Air

I guess my next question is: how efficient would it be to cut the baffles totally out of the hood and just run the stock WS6 airbox with a one piece coupler? Is 3.5" the right size coupler I need?
I'm not really sure how you expect to see power if the engine isn't asking for air (vacuum). Ram air setup... sure run 4" heater ducts from the foglight openings and Y into the throttle body with no filter.
