Crank Trigger
Wondering what the pros and cons are of using a crank trigger over a billet distributor? Does one make your car faster than the other, or is one just better for the valve timing, etc.
Thanks! |
Re: Crank Trigger
The crank trigger should give you more stable timing than dist.. I have dynoed w/both I never have seen real power difference,however if you have mechanical advance in dist. and timing is not stable,can see timing marks moving around bouncing,not staying steady when advanced it will hurt power,and can be fixed usaully by locking advance,take dist gear off ,shaft out,under where weights are there is nut that takes 11/32 wrench remove it w/bushing and rotate 180 degrees where there is hole that stud will fit through and reinstall nut and reassemble dist.
One advantage I see w/crank trigger is when using alot of retard,like with nitrous is that you can phase rotor when timing is retarded. There maybe some power in crank trigger,but have seen alot change and not go any faster. Crank trigger or dist. won't have any effect on valve timing,they will only effect ignition timing.

Re: Crank Trigger
I am no expert on this subject, but I can give you feedback when I changed to one. Mike is right when it comes to the stable nature of the crank trigger. The marks were very stable, which allowed for small adjustments to be made. The other change I made at the same time was installing a Jessel Belt drive. You cannot believe how stable the entire valve train was. Quieted the noise and vibration completely. No numbers to back it up but the engine was making more power. This was a big block Mopar.

All I can tell you is claims of more stable timing aside, my 950HP engine, turning 8000 in the lights in my nearly 3200 lb. ride that makes 250+ passes a season, prints time slips WITHOUT a crank trigger and no belt drive either.
