upgrading mass air meter
 

i have a 1994 mustang gt, and i'm planning on making 350-400 horsepower. i was wondering if changing to a 73mm meter would make any difference on a stock motor, and would it cause driveability problems. i'd like to get the c&l meter because of their adaptability with changing sampling tubes. does anyone have one of these? how's it working?

I think you will hear both good and bad concerning the C&L meters. I used the 73mm for four years and never had a problem. I even made 400rwhp with the meter in place. The only issue for me with that meter was clocking it on my powerpipe to get the car to idle and drive smoothly. Once I found the proper position, it drove great. I now use the C&L 76mm and it works great, no clocking necessary. I would say the 76 is the beter maf but I'm not sure how much of a difference it would make over the 73mm on a stock car. Good luck.

what is "clocking it on my powerpipe"? how do you do that?

Think about looking at the meter head on and using clock position to determine the top of the meter, the electronics. Normally, the electronics would be on top, 12 o'clock position. Then turn the meter left or right. Turning it 90 degrees to the right would be 3 o'clock. That's what I meant by clocking. My 76mm maf works fine in any position.

ok, thanks. that should help if i have idle problems.
