MAF sizes 73 vs. 76mm, etc...

Hozer 88GTConv · 02-18-2002, 10:53 AM

Are there any clear advantages to upping MAF sizes (i.e 73mm to 80mm for example) that anyone knows of?
Also, I was wondering if anyone knows of air velocity benefits using a smaller MAF with a bigger Throttle Body to utilize the Venturi principle to increase airflow. I can't find anything on the subject, except that bigger is better. Thanks for inputs...

If someone knows the answer to your question, they're not telling. Try it on a track or chassis dyno and tell us what you find. I'd love to know the answer.
