Diaphragm vs. Borg and Beck.............

I data log weed burner. But I disagree with about 98% of what you say. Not a fan of using screen door parts to control a clutch you can't adjust. And it's not just me that thinks that. Never seen a Comp guy use screen door parts. Never seen a stocker or super stocker use that crap either. Don't be offended. We just disagree.

There's a lot of "monkey see, monkey do" in drag racing. Don't expect the guys using my stuff to point it out, hard to maintain any competitive advantage if they did. I can't tell you who most of my customers are, but many make more power than a competitive single disc can hold. There's also a few record holders sprinkled in. Some stick classes have even added rules to keep us out.

Here's a link to one of my customers that does not mind being "outed". He's Hilborn's EFI tech guy, who had big problem with his '56 Chev street car breaking Dana 60's. My ClutchTamer was a last minute fix for him, he called a week or so ago thanking me for saving his Drag Week... Drag Week 2016 | Hilborn Fuel Injection

I also have an easier to hide version that does exactly the same thing as the "screen door parts", just much less convenient to adjust. It's a relatively small threaded body cylinder that was originally developed for industrial motion control, basically controlled slowing/stopping of a moving part. Easy to hide, mounts much like a clutch switch...

The threaded body version can also be mounted under the car, to control the clutch release at the clutch fork. Much harder to detect down there in the tunnel.
