My DIY Throttle Body Sync

[bullfighter]

It's always fun to be a MacGyver, so I thought I would share pics of my latest project: a home-made manometer for DIY balancing of throttle bodies.

Baby's running MUCH smoother now, especially in the 3-4,000 rpm range!

Nice
We used to use a similar contraption on the 4 cyl Hondas back in the day.

This is off topic but nice R. I have an 04 just like it. Not many out there with that color combination.

Be carful if you use mineral oil in that they may think it's a medical device and hit you with the medical device tax!

Do you mean mineral oil or castor oil?

Very nicely done!

I used one of these for years on my airhead but it way too sensitive/jumpy for the oilhead so had to buy a real one one.

Okay bullfighter, how about a materials list?

Cannot make out what the clips holding the tube next to the yard stick are in the picture or what the anti-kink radius piece is at the bottom.

And what was the liquid? ATF?

Need to run down to the hardware store now it looks like.

Many Thanks

I used one for years on my R1100RSL, as a final fine-tune after getting a rough balance with mercury stix. Since you are working one side against the other, all differences are magnified by 2 so yes, it can seem jumpy or sensitive. That can be fixed by adding a small restrictor in each line, like a fitting with a smaller hole.

Best,
DG

I don't recall the diameter of the tubing, but I bought 15 feet of it at the local DIY Center (used to be "Do-It Center"). I looked at a few YouTube videos for inspiration, they said to make sure the length of the tubing is equal on both sides from the radius out.
The clips are leftover cable clips I had for running cable up a wall.
For the anti-kink at the bottom, I used a plastic cap from a jar of vitamins (super high-tech, I know!)
And yes, the liquid is ATF (which is vegetable-based oil, so not subject to medical equipment tax, LOL!)
And to top it off, I screwed a couple of eyelets into the top of the 2x4 to hold the tubes when not in use.

Perfect. The close up picture was what I needed. Thanks.

The tubing is all I need to pick up. Have everything else already.

I will be fashioning one very soon.

Thanks! I love this color combo too, it was quite the find

I thought I'd post my version of this instrument.
Can easily checked to see if the gauges 'match' ( accuracy not important if they concur with each other. ), doesn't use any liquid, can be damped easily enough and is robust, although its a bit more work to build.

Also one has to source econo gauges out of 80's Ford Falcons..... Not too much of an ask in Australia( see them on Ebay a bit ), but maybe harder in other parts.
I think VB/ VC Commodores use something similar.

The valves are the 'needle' type so they can be throttled.
