Optimizing the TB - CEG Archives

Contour Enthusiasts Group Archives

Does anybody live near the St. Louis, MO area that knows how to optimize a TB? This is the last modification I need to do before purchasing the "chip."

I am willing to drive to the location, and pay the person $80 for their time and effort.

This is VERY important to me, and any volunteers would be GREATLY appreciated!

$80 will get you a nice Craftsman dremel, some countersunk screws, and you'll still have money leftover. And this way, you get a dremel out of it, and some experience.

I'm not taking the chance of ruining my car by having a screw back itself out and shoot down my intake manifold (yes, I've heard of this happening before).

I've already stated that I'm not a mechanic, and most major processes I've tried, have ended in a dissaster.

About the only things I concern myself with are:

changing the oil, changing headlights/blinkers, and cleaning the UIM and TB.

My own pops (who has worked on many a car in his day) won't even touch the concept of boring out the TB.

The offer is out there, and I wouldn't have put it out there if I could do it myself. After watching someone ELSE do it I MIGHT be able to attempt this. But I'm no machinist, and I wouldn't be crazy enough to pretend I am.

Your advice IS correct Mark, doing this myself would be the BEST idea. I just can't afford for something to go wrong.

These kinds of things are better left to the professionals.

You don't bore out the TB when you optimize it.

Send me your TB...$80...and I send you my optimized SVT TB.

You'd figure as I own a SVT..the TB would be off said SVT

I hope you are reffering to an SVT TB. 80 will almost buy and SVT TB and the parts needed for the install.

its really easy, just do it yourself.

Didn't buckshot used to offer these? I'm assuming not any more?

Exactly. Maybe this is why Ike thinks this is such a tough job. You remove the plate, and pull out the shaft. There are two sides of the shaft that the plate goes between. Just hack one of those sides off with the dremel. Put the plate back in, and throw in some countersunk screws. Voi-la, optimized T/B.

You can take it even further and dremel down the uneven "ridges" inside the TB. Knife edging is also an option.

Thats a little more extreme, its also prone to over dremeling and then you need a new TB

Knife edging can be. For the ridges, it's not "prone" to it. There is plenty "meat" there - unless you go absolutely crazy with the dremel. I've optimized ~6 TBs and never had a problem.

optimize mine pete?

I still do offer it, just not as a core exchange service so you have to actually send me your TB and I'll optimize it right away and send it back.

When I said "bore" I was referring to the process in general. I'm aware that it's a countersinking screw process.

"Countersinking screw process?"

Looks like I'm gonna have to find a spare TB then.

Dremeling down the edges to remove the ridges will work but will not give the best/cleanest results and can take a lot of time. I have done a few and along with modifying the TB shaft on a Milling machine (not by hand) I taper the intake side and the output side of the TB on a lathe to get a perfectly smooth finish and even transition from the 60mm bore to the outer edge. Also by doing the TB shaft in a mil you get precise accuracy and a perfect countersink on the TB plate. This is an example of what Pete is referring toâ�?�¦these are a SVT TB non-optimized and an optimized 65mm Mustang TB. Note the outer edge difference between the two (the TB shafts have not yet been done in this pic), the SVT edge is thick and the Mustang is very thin â�?��?razor likeâ�?�. This eliminates any ridges from the intake tube into the TB creating smoother airflow.

i was thinkin about doin this to my TB but can someone write specific directions that i could follow.... thank you

Search...and ye shall receive...

I optimise TB's too. If you want more info - PM me.

When I get my truck running, I will hold you to that Stazi.
