I purchased a second throttle body, and I want to know who to send it to. I hear people talking about the 55mm from Howell, and people talking about the 57mm from ARD. Which one gives more results? Also, I was thinking of buying a second intake manifold so that if I do send my TB to ARD I can send my manifold to them aswell. My question on the manifold is does anyone have an extra one that I could borrow? I'll be glad to pay for shipping. Because I can get one here in my city (Jacksonville, Fl) for $70 but I don't want to have a spare manifold after mine is ported. Unless anyone is interested in buying them (stock manifold and throttle body) as well, I'll be glad to cut a deal. Not really looking to make money, but don't want to spend too much on extra parts that i won't use. I really appreciate anyone's response. Thanks

The Howell TB is 55mm and works really well so I here. ARD just started doing the 57mm ones but no one has put it on yet and posted results. Super20g got one but he hasn't got his car back together to post results and Fate is getting one this week hopefully so maybe he'll post. I am going to get my TB bored out soon pending the results of the ARDs. But the howell 55mm works good so its up to you what you wanna get.

Where does ARD do the job, whats the turn around, i live in San Diego, and i can be with out a car for a few days, if the price is right, and it's not a lot of hassle i can give it a try....I'm NA so i don't know how much of a gain i will get, and how much info i can gather, but maybe i can do something.

ARD is in houston and turn around should be about 2 weeks so I would suggest getting an extra TB then selling it back after you get yours back.
