so 3.5lbs of aluminum removal ... would be curious if anyone else tried this and got the same outcome, I was curious as I could feel it when I picked up the stock vs ported plenum

My garage floor certainly knows there were 3.5lbs of aluminum... pretty sure my wife noticed it too lol

Added bonus. Less weight equals more speed.

Old rule of thumb: 10 pounds removed equals +1 horsepower

So this rule of thumb should apply to driver too? [emoji38]

So the best way for me and my Z to have more pep is to lose 40 pounds. How can I make an appointment to be ported?

See your doctor, but he'll refer to it as a colonoscopy.

Great post. This is win/win weight reduction.

as graham chapman says " I don't chase, hp, I chase power to weight"


I lost 40 lbs this year, and my Z isn't faster, but my zero to off my @$$ time plummeted.


Secret to the weight loss, pretend the fork is too heavy to lift and you are too tired.
