Notice a loss in low end power?

 

ummm i dont think so. it pulls good at 2k at light acceleration. but its seems like it gets up past 3k alot easier.....not sure if that constitutes as a loss of low end.

 

Does it pull better at 2 grand then it did before?

 

yeah.

 

I would like to get TB this summer but can't decide which one I want. Theres a person on dak-dur that will port the stock one, which is supposably really good. Then there are 68mm and 70mm ones...

Bigger is not always better when it comes to TB's.

 

what is a ported throttle body? what advantages does it supply?

 

i thought Dan from fastman did a ported tb? its the stocker but just bored out to 68.5 i think. he claims that the 68.5 bore is the best for the 4.7. spending 400 on an f&B or 300 on a BBK is not worth it.

 

isn't porting what they do after they bore it to shine it up real good.
looked shiny in the pic. i guess it helps air flow a little more.

 

Yeah, they bore it first.

And from what I've hear, a bored stock TB is the best for the 4.7 as well. And they are only $100 as opposed to $300 or so. It's kinda like exhaust. Having a 3" exhaust all the way back will kill your low end and so will a TB that is too big.
