I am in the process of making a prototype hand throttle much like those that were used on 914-6 cars. For those of you who are not familiar with them it consisted of a lever mush like the heater lever that used a rod that ran through the tunnel up to the pedal assembly where it pushed on the accelerator lever to manually open the throttle for cold warm ups.
I think I can make the modified lever rod, bracket and modified accelerator piece and sell it for about $150. For all of you guys running carbs do you think there is a need for it? Bruce |

I am interested but you knew that... You are using my partial to reverse engineer I assume (IMG:style_emoticons/default/biggrin.gif)

Rod that pushes the pedal assembly doesn't seem like the most efficient approach.

It seems to work OK on the original -6s! I only wonder how many people actually would need one these days, more and more of the newer conversions will be injected and the carbs are probably going away.

Even with an FI engine, you could use it as a crude cruise control. Even with a -4 engine!

They're definitely cool, and I've thought about making them. I can't say that I'd be ponying up to get one personally, but I would definitely promote the use of them to other people.

I think it's a great idea... the hand throttle is invaluable to me when starting and warming up the 911 on a cold day.

I'm interested, my right leg become very unconfortable on long drives, it would be good to be able to change positions without having to stop-and-rest. I have a Rennshifter and would need to have a slit cut in hte base for the handle to fit.

I might be interested. I have one on my 911 with PMO carbs and I'll be honest I don't use it much. Now keep in mind Florida generally doesn't get very cold and my PMO's I only have to feather the throttle for 15-20 seconds and they settle into a smooth idle. I'm guessing Webers may need a little more help. I have Webers on my GT clone.

The hand throttle sounds like a nice tool for warming-up a cold engine, but quite frankly sounds dangerous as a "cruise control" as mentioned above. If your'e cruising down the road and have to react quickly, having the motor physically reved at cruising speeds is asking for disaster to strike. Perhaps I don't understand how the hand throttle works...does is release if the brakes are applied?
Another option for the "warm-up" idea, is using an "idle compensator" (on every junk 80's car) or Edlebrock sells them as well. Mount it to push your throttle linkage and put a on off switch in the cabin. It's throw is adjustable as well. Here's a pic from my v8 application. It also works well for you teeners that have added AC....great way to increase the idle speed (if needed) when the AC is on. (IMG:http://www.914world.com/bbs2/uploads/post-4253-1234157582.jpg) |

If your'e cruising down the road and have to react quickly, having the motor physically reved at cruising speeds is asking for disaster to strike It's only dangerous if you aren't paying attention. (IMG:style_emoticons/default/poke.gif) That means 99% of USA drivers are out! (IMG:style_emoticons/default/lol-2.gif) Anyways, i've done a few long distance roadtrips in the 914 and every time i wished i had some sort of cruise control. Hwy 80 goes straight through the desert for almost 600 miles with absolutely nothing between Reno and Salt Lake City. A hand-throttle would have been a soooooo nice ...

(IMG:style_emoticons/default/popcorn[1].gif) Andy Thank to all for the comments. I would not recommend it as a cruise control either. I wonder if the original 914-6 owners manuals commented on that use? I have see how much work it is to build one. Rob, (conedodgger) Since you gave me the idea you will get the first trial. The part you sent me is not needed and I will return it. Bruce |

Those of us with very early CIS/6 conversions ['73-'74] should be interested, too. Each morning, to start my CIS/6 conversion, I have to crack the throttle pedal slighty to fire it up, then hold the pedal at fast idle for about a minute to keep it running. After about a minute, it will idle without stalling.
A hand throttle would be 'nice to have' each cold start. |

I like the idea Bruce, my carbs spit for 30 seconds or more. It is always a bit of a chore for me to keep my idle uniform during warm up. I am interested to see what you put together.

I had to reengineer mine so i could retain the center console, worked great for setting the break in RPM on the engines first start.
