The positive reviews here have me looking hard at a 123Ignition dizzy replacement on my '73 2.0 w/ stock D-Jet.
But, the version they offer for the 914 that's compatible w/ D-Jet (123\PORSCHE-4-R-V-IE) has a fixed 8000 rpm rev limiter. The thought of my motor turning to shrapnel at 8000 rpm is a just tad bit worrisome. (IMG:style_emoticons/default/icon8.gif) Ed at 123 Ignition said that the OEM rev-limiting rotor won't work in their dizzy, and suggested an aftermarket stand-alone rev limiter. But, I'm not too enthusiastic about adding an extra box at additional expense, just to limit revs. Has anyone here used the 123Iginition w/ D-Jet? What did you do to limit rpm? Anyone just run without a rev limiter? Thanks. |

You want no more than a 6K redline and never use a limiter as a shift indicator.
Depends on the cam but torque drops of at 5400 rpm with most cams, some hotter street cams it's about 5600. |

I was more concerned with somebody over-revving the engine accidentally and thought the rev limiter would be a valuable (essential?) safety valve. I do know how to drive, after all.
