[QUOTE="Catmonkey, post: 16538281, member: 124025"] Most of the modded cars here are running a MAF in the 120mm range. On the later cars, it should be good for a bit over 800 at the wheels. The tube size has more to do with air flowing through a bigger tube that slows down the air signal sucked through the tube for the MAF sensor to meter airflow. You change the flow rate through the MAF transfer function. It's just a matter of changing the resolution of the sensor. A 123mm MAF will hit the higher end of the table approaching 850 hp, so a bigger tube is need to extend that range. What you gain up top you lose on the bottom. You're not going to find a throttle body that will outflow the tube, so the tube size is somewhat irrelevant in the grand scheme of things. My mods are in my signature. I'm running a Whipple 123mm MAF meter. My air tube is a used JLT 123mm that I cut to size to work with the MAF. [ATTACH=full]1676746[/ATTACH] [/QUOTE]
