Head Hoggers ported TB test. 

Here is a example of our ported throttlebody we do. This is a SE 64mm for the Milwaukee 8 heads. The blue line is stock out of the box test. The green line is our modified SE 64mm throttlebody. There are big gains from how we design and modify the throttlebodys. We see a lot in wet flow we do, this allows us to see fuel patterns and the slower speeds through the track. After our modifications we can increase CFM while maintaining 220-240 feet per sec on velocity. This is key in making heads work right!
