Are you really getting full throtle?
 

While doing some maintenance on the car today, I removed the intercooler and decided to check the throtle opening, to find out that at full throtle (pedal to the floor) I was getting about 3/4 opening. Lots of looking around and probing here and there to find out that the pedal itself has a rubber stud on the back which limits the travel. I cut the wood floor pannel to allow more travel and WOW what a difference at full throtle. Guys check the throtle opening in your car, you might get a surprise, and realize what you're missing.

The linkage itself has a top limiting the travel w/o damage to the system, and the the pedal rubber stub was not allowing to go all the way through, now the linkage goes all the way to the stop, how it supposed to be.

Thanks for the advise.

Still, the way you've done it is a kludge. There are reasoons why the linkage is adjustable.

How do you adjust the linkage on a 930?

There are a variety of places all along the course of the linkage, from where it fastens to the gas pedal to where it finally reaches the engine, where there are threaded rod ends with stop nuts that allow you to lengthen or shorten each piece of the linkage.

I'm not saying it's easy...frankly, I tried to adjust mine (like you, I was getting about three-quarters throttle) and finally gave up and took it to a shop...but you're right, it is important and there are probably a lot of 911s out there that haven't for many years experienced full-throttle acceleration.

You might also do a search here. I'll bet this subject has come up before.

Thanks.
The link aft the pedal (easy one) is max'd out already, others are - as you say - a PIA to reach.
I'll keep working on it, meanwhile enjoying the full throtle experience :-)

Check the bushings in the throttle thingy ma diddle that is on the motor itself ( the little piece where the throttle body linkage meets the rod coming up from the transmission, I have seen many worn, and will limit the ammount of travel in the throttle

Ditto.

He's talking about the throttle bell crank bushings on top of the motor. They are plastic, and eventually break apart and fall out. New bushings will give back full throttle. They are tricky to replace when the motor is still in the car though.

Bell crank, thats the word I was looking for , I am good for an occasional brain fart. Thanks

It is common for the accelerator cushion to break the rubber inside the steel safety housing. This dramatically limits full throttle to something much less.
