I am thinking about buying a BBK throttle body. Does anyone have any experience or knowledge about them? I believe it is a little bigger and maybe polished. I don't know if it is worth $400 though.

 

I have one and like it. I could feel a seat-of-the-pants change in performance. To get that you need a significant HP change. I have the typical sticking problem you read about in other threads and need to lightly sand/file the edges of the throttle plate but haven't yet. If you are patient you can get one off of ebay very reasonably priced. There are a couple other sources that rework OEM models with what sounds like good success. They tend to be more popular due the fact that cost less. The BBK is 80mm. I am not sure what the OEM size is. I am sure someone will post a reply with the link those threads.

 

The stock is about 77mm I believe. That is also the size of the hole in the stock intake.

Those are about $140.

I can see using an 80mm with forced induction or big cubes. Most seem to be okay with just a ported stocker.

I will add a sig when I feel like it.

Thanks, Jim

 

I saw a post in external engine where a baur TB dynoed better than a bought brand name TB the guy din't want to say which brand of TB he used to compare his ported one to... so with out forced induction or NOS they say that the ported one worx better... too bad i had already bought the BBK i am porting my own... i'm going to compare numbers at the track...

regardless from what i have read the ported ones are definately the way to go.

 

if money wasn't an issue, wouldn't the BBK be better plus easier so I don't have to loose my truck for a week or so to get it ported? or do I port it myself? What is all of this ported business about? I am also eventually going to put a 150+ nos system after I do my rebuild in a year. So would it just be better to get the BBK? Please comment.

 

Ken, I think they must be smaller on the Vortech 350's vs the 4.8-6.0 ones.

Y2K, they seem to be in good standing with the LS1 guys over on that www.ls1.com site. I have read only positive things about them there.

$140 ported or $400 BBK... like I said, unless you have internal mods you will be fine with a ported stocker. I can put that extra $360 towards something else.

Coonass... No, there is no down time. You mail the $140+core charge to Shaner. They send you a ported TB. You swap them, enjoy the gains, and mail your old one back for the core charge. Pretty easy.
