When I purchased my '90 C4 a few years ago I discovered that the wide open throttle cam gear was missing. I fabricated a temporary fix using a RC servo bell horn which works great BUT I'd prefer to install an OEM part or mill a new one.

If anyone is willing to sell me their WOT switch please drop me a PM.

Or, if anyone could send me the part dimensions I'll mill one myself.

Thanks!

Will do! If anyone else has a switch please still reach out to me. Thanks.

Your RC bellhorn idea saved my scheduled dyno time, thanks!
I built a 3.6 for my 911 track car, but the throttle body was apparently from a Euro ‘95 993 which had a potentiometer on the full throttle side instead of a full throttle microswitch. I’ve been trying to find a correct TB but was able to remove the pot and install the correct full throttle switch and fab a bellhorn to trigger it to get on the dyno. Took at most 15 minutes to modify the bellhorn and install it, Works great!
Good news is that with the ECU able to access the Steve Wong custom full throttle maps the engine put 268 hp to the rear wheels on a Dynojet set to SAE with smoothing factor 5 to satisfy NASA requirements, and 276 rwhp set to standard.

I have these available if you need one.



They are aluminum and attach with a set screw.
Pm me if you need one. The plastic oem piece always breaks (eventually)...
