Don't knock something just because it's out of your price range
The 62mm tb's boast little to no tuning and stock driveability...
And we are really not talking bigger here, its more just matching the stock/aftermarket manifolds sizes to the tb size. Ford knew what they were doing when they made the manifold bigger than the throttle body opening, $ for them to make on aftermarket upgrades.
I did do some searching and saw that on the 10 psi stock long block average setup gains were small and it mostly moved the peak curve to the right with the jpc intake, which makes sense since thats not what its designed for. And as the same for the other intakes can be argued that its due mostly to the cmc deletes. I do agree its a nice, well made piece and should work nicely if you ever build the block up and up the boost. My point is at your level the stock manifold with deletes and a port matched tb would show the same if not more gains than the jpc intake for alot less $. I agree calling jpc is great idea, straight from the horses mouth.
I still wonder how you think a bigger than stock tb wont have gains due to others reccommendations, yet decided on your own that a racing intake manifold was a good investment at your power level. That money could have went towards some forged internals! Just my opinion man, not trying to piss you off.
A larger TB can in some cases lead to driveability/tune issues that aren't worth the gains. For a street car or even a street/strip car, alot of time is spent at tip-in and part throttle rather than WOT. It's not only the cost of the TB - it might mean extra time and cost in tuning or less enjoyment of the car on the street. Bigger isn't always better and a good understanding of the costs and performance tradeoffs in any build can maybe help avoid unanticipated consequences.
Where did I say once that they were a bad idea? I just said that there's more to consider than just the cost of the TB. Depending on funds availability and build objectives they might be worthwhile or not. My point is that someone should go into the decision with all the information - not just a "bigger is better" mentality.
You need to stop getting a fucking attitude with everyone.
I have no drivability issues what so ever with my JPC manifold, and I built it myself, and I paid less for it than most people pay for a monoblade throttle body.
JPC kicks ass.
This manifold on my car gained me 40rwhp. It was covered in MARCH 2010 MMFF and it was with the stock TB. Mike Dez (our tuner) has no problem with tuning as does many other tuners that post on this site. Their used to be an issue with tuning these cars because of the poor TB internals but times have changed and it's easy now and most companies fixed their issues. The FRPP that is made by ACCUFAB pretty much nailed it on the sport with the 62mm and the CJ for the shelby's.
There are a lot of people in here with a lot of knowledge; but as it stands, the question asked was which throttle body works best with the JPC manifold.
So naturally, the people who have JPC manifolds should be the ones posting in here.
The answer is that it's impossible to answer the original question without knowing the goals and budget of the particular build in question. There is no one right answer for all applications.
Only if you've tested every possible TB on your JPC manifold.
When trying to chose the best part for a particular application it's important to define:
- what you're trying to achieve;
- how much time, effort, and money you're willing to spend; and
- what other performance tradeoffs you're willing to suffer.
It doesn't make sense to answer a question like the OP's with an absolute without considering the above.

The goal for choosing a TB is to optimize the advantages of the JPC intake without hurting driveability.
