History: |
| Dodge introduced the 4.7
engine and started with a 65mm Throttle Body. In 2001 Dodge enlarged the
Throttle Body to 68mm and is the size still used today. |
|
| IMPORTANT! |
| Both the 65mm
and 68mm TB's are really 3mm smaller than advertised because of the restriction
above the throttle blades. |
| The Fastman
4.7 TB's remove this restriction and are a
True 68.50mm bore all the way through. |
|
| Recommended
sizes: |
| Working with
the 4.7 motor has shown 68mm to be the optimal size for street performance use.
This is the size I recommend. I can machine both the Dodge 4.7 99-2000 65mm and
2001-present 68mm TB's to a
True 68.50mm
bore. |
|
| Other
sizes: |
| I can
machine the 2001 and newer 4.7 TB's to bigger sizes of 69, 70, 71mm. Testing
has shown the gains to be minimal and do not recommend them but I will build
whatever you want. My 68.50mm TB breathes all the air your 4.7 TB will ever need.
This includes a Kenne Bell blown 4.7. |
