So here's the scoop. I just purchased a built inline pro motor that will be refreshed and I have my old motor which is sold. My old motor I had the Billman TCT and the new IP motor has their TCT. I was only familiar with Billlman's product so I decided to break them apart and check the differences. IMO it looks as if IP's has a better setup for tension but I'm not entirely sure. The IP TCT has a much stronger spring setup. Is that a good thing? Or is too much tension bad? I can push Billman's in a out more easily than the IP which takes a bit more effort to compress. What's your opinions on both and which one should I keep for the built motor?

Inline Pro's model
-beefier large spring
-beefier plunger thing
-smaller small spring (more tension)

Billman's GenX
-large spring isn't as thick or long
-small spring is longer (but easy to compress)
-plunger is shorter, head is smaller also.

Give your opinions on which one I should keep and vote for one above!

 

Could you post a photo of the two? Or at least one of the Inline Pro model?

Thanks!

 

I went with the Billman GenX for the hardened internals.

 

Achieving proper chain tension will come down to more that a voted opinion. It's all about the amount of chain tension for your particular engine. Specifically, the current chain guide operating depth.

My tensioners are application specific. How the engine is built will determine that. We can go over the build if you like, and I can tell you if the standard X is applicable. I don't know which one you have, but the coding on the front side will tell.

The tension they both put on the chain is very different. It is also achieved differently. Mine does not use bigger springs that raise the chain tension. It is controlled by the housing, which is also different.

I am more than happy to walk you through procedures to determine your current chain guide operating depth on the new build, and set the chain guide pressure perfectly. Can PM, or discuss here.

 

From my understanding the Inlinepro tct is more of a "drag" race setup. I.e. Lots of unneeded tension and pressure. Too much tension is not a good thing, it will wipe out the guides, the bearings and the chain. The Billman applies oem tension on the chain and compensates for wear and stretch.

For or what it's worth, my car has 5,000 track miles, over 100k on it and I just took it on a road trip of 10+ states. If your going to drive your car, get a Billman, if it's going to be a trailer queen that only sees the strip, try the inlinepro, if it wipes out their motor, they'll have to eat that right?

 

Like most of us here I don't have the knowledge or experience to evaluate most hardware so I go with recommendations from experienced vendors and users. Billman has been right on for many years and the people that use his stuff have been very happy... so I bought a TCT from him and have been very happy with the performance. It really does not make any difference to me what the internal components look like.

 

.. I know how bills tct functions .. in turn I know why other tcts malfunction ..
ill come at this another way .. if you are not smart enough to take it apart and understand why bills is right , than you can not try to conclude which is better by looking at the internals ... cause you don't know what their purpose is ..
any one who does their homework will end up with bill tct..
all others .. go with god lol or a step under him .. Billman !

 

Ohh and my car has 260 k miles boosted for 50 k.. I attribute a lot of that to Billman

 

Why does the engine need this much pressure on the timing chain, for drag racing? Sounds excessive. You'd think this would subtract potential HP, as well as cause premature wear?

Thanks!

 

Perhaps it's for guys who are doing full boost launches making over 700hp. I don't think it's common on our engines for the cams to come out of timing, but I guess it would reduce the likelihood of that.
