I'm ordering my "parts" to improve the performance of my V-10 and have a question. I'm installing a Banks Power Pack: 3.5" exaust, Headers (TorqueTube exhaust manifolds), and Induction package, and a SuperChip.

I'm also considering installing a FRPP Hi-Flow Oval Throttle Body (M-9926-D464) and have the following question:

Q) Does increasing the size of the Throttle Body help or hurt low end HP and Torque?

I though I'd share some info I've received regarding my idea to install a larger Throttle Body on my truck.
I found out that the BBK twin 62mm Throttle Body is indeed built for both the Cobra 4.6L 4V as well as the V-10. The comment that the linkage was shorter than the V-10's is incorrect. Since it is larger the throttle plate dosn't have to open a much to flow the same air, and as such makes the accelerator more sensative.

I found out that the Ford Racing Performance Parts (FRPP) Hi-Flow Oval Bore Throttle Body (# M-9926-D464) designed for the Cobra 4.6L 4V will bolt up to and work on the V-10. A good source that was passed along is that the V-10 dosn't flow enough air to cause the production throttle body to cause a restriction and using this (Hi-Flow) throttle body would be a complete waste of time and money. The recomendation for improvement was a larger/better flowing air cleaner and air meter combination. Also don't expect to see any performance parts from FRPP, at least anytime soon.

Looks like the Banks and the SuperChip will have to do for now.
