What performance benefits, and associated data/proof, do the vendors who offer them tell you to expect?

I'm running a fastman modified stock throttle body ( 95mm + 4mm shaft) . The first thing I noticed was increased throttle response . I never did a before/after dyno . A throttle body in my opinion is a supporting mod .

I haven't seen any reputable data, that's why I wanted to hear what other owners have to say.

That's because there isn't any. More snake oil - when you need a 105mm throttle body, you'll know it.

I don't believe it's a huge power increase but when you are chasing every little bit you can get it definitely helps . I have no regrets and I notice it if I put a stock TB back on.
There was someone on the other site who dyno the fastman on his car . It was worth 5-7 rwhp and 25-30rwtq.
I will see If I can find the tread .

I don't think it's snake oil . It comes down to how much are you willing to spend on $$$/HP .

On a stock blower a 105mm TB definitely qualifies as snake oil. Your 95mm most likely suits your mods better, as you stated it is a supporting mod. But, on a stock car there is little reason to look past a mildly ported stock TB.

You'll know you need to address the TB when the datalogs indicate a restriction - this is very evident on NA motors when they are not at barometeric pressure at WOT (meaning there is a restriction in the intake manifold forward).

Don't mind me if I see more opinionated than normal - I am on cold meds and should probably stay off the internet. ;)

I'm definitely not talking about 100mm or larger TB. I agree that is to large for mods I have or will ever have . I can only comment on what I have . A modified stock throttle body that is 95mm(plus I like the stealth look) .As I stated it's a supporting mod . I'm not telling anyone to run out and buy one the OP asked who is running a larger throttle body so I answered. I wish I access to a dyno at a reasonable price . I would love to add that to some testing . Flow numbers, drag strip, and dyno testing would be nice .

Nah your not opinonated . Your more of a hard facts kind of person in my opinion. I like to test things for myself . Sorry but I don't trust a lot of people and stuff on the internet so it's the only way I can find out for myself. Sometimes I win..... Sometimes I don't.

Shiiiiiiiiiiiiiiiiiiiiiiit... 105mm was never mentioned in this thread, I must have had a mental layover from Facebook earlier(?).

Damn meds.

But, yeah - port the snout and add a matching TB is just good practice.

Lol . There was another thread on a 105mm throttle body. That might be stuck in your brain. . Now excuse me while I run out and install my new 1150 dominator on my slant 6 ......

Engineered Automotive down the street from my shop has a nice dyno setup. We did some runs there with some members with my 16 cat. It was like $75 for 3 runs.
