Hey guys wondering if anyone has tried them? ?Looks like the offer sizes from 90mm to 102mm. In the pictures the look pretty good (look like FAST copies to me), also there are much cheaper.

 

Cable driven?

 

I use one on my engine test stand, works fine for the test stand lol

Yep cable driven.

 

A car I tuned had one. It did the job. I had to slot the tps to get the right voltage.

 

Some guys over on Ls1tech talked about these as well. They are decent as long as you are N/A but i wouldnt run one with boost because the spring is too weak. Some had problems with the IAC motor fitting but others didnt. Guess its kindof a hit or miss.

 

I am sure the spring could be changed out the price difference is huge. I wonder if these will turnout like the eBay headers.

 

I've read and heard good and bad about those.

 

One way to find out.

 

Wow, doing a quick ebay search resulted in the Chinese knockoffs ranging from $107-$1200. I would imagine if the cnc programs were correct, the physical differences between the FAST, NW, PTM offerings aren't much different from the knockoffs. However, with the name brand US tb's I am sure you are paying more for a more conscientious assembly of the unit and a good bit of liability insurance. There is a lot that could go wrong with a poorly constructed tb that failed to open/close properly.
