maf and throttle body diameter

[Homeboy981]

Here's a pic or two. Will have to compile parts list.

You start with a HUGE CONICAL filter…(this was Stage1-notice MAF is by the filter)


Then move the MAF so that it is practically sitting on the Throttle Body (Stage2) - using the Honeycomb to straighten the airflow before the MAF & TB.


It is 4" until it drops to 3.5" at TB.

Enjoy! I sure am!

homeboy - do you have that filter enclosed yet? otherwise it's drawing hot air from the engine compartment. I did a quick search and here's some math for you:

cool with the half second increase in zero to 60 times. also like the idea of filing the TB; the 1/8" lip on that thing always seemed wrong to me.
