Looking at increasing the size of my throttle body. Any thoughts on this topic?

why ?? you adding a blower ..

The OEM throttle body can already support big HP numbers if the engine is naturally aspirated. As techrep implied, unless you're adding a supercharger, the stock TB flows plenty of air to meet the needs of most any bolt-on mod.

The stock 75mm throttle body which has an 80mm opening flows around 800cfm. Standard calculation is it takes 1.5cfm's to make 1hp. So 800/1.5=533hp.

My truck is super charged and I found and measured restriction in front of the throttle body developed at 11psi of boost and 4000rpms up. Which would be right in the 550hp range.

That's when I ported the Whipple to match the new 90MM Ford Motorsport throttle body and went to a 4" intake setup. Should give you some idea about when a throttle body is needed.

I would add a TB spacer and a Tornado gas saver as well as a larger TB.

Good one!
I haven't seen that much misleading info since I watched a TV evangelist. Lol
You forgot the part about a chambered piece of crap Flowmaster muffler.

There is a Flowmaster rep lurking here, you may start a fight! I have a Magnaflow awaiting installation in the bed. Hopefully quiet this nasty *** down

Ha! I say bring it on. I've said it before and I'll say it again. Flowmasters belong on 80's Camaros on blocks in the trailer park. Horrible product and even worse flow. I know there are people who like them and that's fine. To each his own. These are the same people who think thier Honda and Yamaha Crusiers "sound just like Harley".
