I take exception, I posted a viable solution. I know I have seen a bracket that mounts from above but I couldn't remember who built it. I did post one that is similar. So there! NahNahTounge

Besides, I'm old and old people get a pass when they forget something!

None of that was asked about by the OP.

30 years for my dad, another 25 years with me, never had a crank trigger fail. Not even back in the day when it was a steel trigger on the wheel and a magnet on the pickup instead of the new fangled "flying magnet ones of today.

I started using crank triggers in the early 1980's.

Had one small block that had ridiculous cam walk and timing moved so far it was crazy when you revved it.

Ran the old Moroso stuff and one day a washer must have bounced up and wrecked pickup. Can't recall if I had a spare or not.

Fast forward to late '90s and my old dragster.

I went to a Terminator after a couple years on gas carb.

Mounted fuel pump stacked on top of trigger bracket.

I had the Holley Annihilator ignition in that car and it took 3 of them to get one that worked right ! And their crank trigger I believe.....


First day out with Terminator I'm going rounds but car starts to shutoff at times. I am into rd 3-4 or something like that and scrambling around trying to find whats causing the stalling.

I mess with pump and in the process the trigger pickup gets to close to wheel.

I redlight after car stalls on burnout and has me rattled....

Turns out pump pulley set screws were not real tight and drive pulley was slipping losing fuel pressure.

I find it and fix it......

The next 2-3 outings or more I am chasing phantom missing and I eventually changed the entire ignition system....wasted weeks of chasing it!

The culprit was without a doubt the crank trigger pickup. It was rubbed by the wheel and clearly damaged.

I should have checked it first but wound up overlooking it until I changed everything else. Dumb me.....

When I put my next dragster together I skipped the crank trigger but did intend to install one.

I have had flawless results without it and way prefer NO pickup that is vulnerable to outside issues.


In the business I work for the same type pickups are used as engine speed sensors that send that pulse signal to a controller. They are in close proximity to the teeth on the flywheel and we change them regularly for loss of function.......Often they are visually fine.....

It's just a matter of preference and maybe past experiences with any of this stuff on a racecar.

You get bit by something and it leaves a lasting mark.....


So the two failures you had were caused due to a "Flying washer" and you messing with a pump and let the pick up hit the wheel, but its the Crank Triggers fault?

No it was not the crank triggers fault and I never said it was.

I was just recounting a couple issues I can recall that happened to me and cost me track time and $$ that were related to using a crank trigger.

In both cases not using one would have eliminated the failure no matter who or what the cause of that failure was...

I am sure there were other issues with crank triggers in my group as well as my own.

The old style trigger was more vulnerable with the lugs sticking out.

Like I said I prefer to run without one and you and anyone else can do whatever they prefer to do....

When comparing grid runs using a crank trigger vs distributor, there is a huge difference. The crank trigger is smooth and flat, the distributor bounces around and is not smooth. Looks like it is missing the whole run (at least to me)

My car has a crank trigger, my buddies car does not. Both have the grid installed, mine using a digital 6 plus, his has a 6AL.

I was concerned we may have a problem on his car and sent the files to markemark to look at them but he assured me it was normal for the rpm graph to bounce when using a distributor.

Mine has been on my car since 2000-01.

Those who are against running a crank trigger, have you ever had one? Installed one? Used one? (I doubt it)

Wrong and SCDIV1 has already stated he has as well starting 30 years ago!

I saw SCDIV1's comments, it's pretty obvious his answer and why as he stated them above. I was asking the others who were against this.

Why do you have one on the dragster?

bought the car turnkey and to clarify, I wouldn't say I'm against it, just stating there's no benefit, therefore no need for it so why bother?

I do keep a spare pickup for it as well I change it every season because again, I know numerous racers that lost rounds and/or were chasing ignition issues due to it.

One thing is for sure, the first time I lose a round because it failed, it will be in the weeds and replaced with a race ready distributor.

Every nationally know engine builder in the country uses and installs crank triggers. And since that's the only criteria in which anything should ever be judged, Ed is wrong.

Just truth and facts

So you have both, see, I respect your opinion much more now. I still feel you are wrong though.

On the dragster, you can bolt the crank trigger on and phase the rotor on the engine stand. You should never have to put a timing light on it (Unless your one of those guys who absolutely has to check it) Once it was set up, (before you bought the car) it should never change unless you physically move the pick-up.

When you put the engine in the Firebird (I'm assuming you do this yourself) On first start up, you have to check the timing and set it. And I'm sure rotor phase is not the easiest to check with the distributor under the cowl panel. It would make more sense (to me) to have the crank trigger on the bird and distributor on the dragster due to ease of access for both.

I agree, there are no performance or consistency gains but the crank trigger is MUCH easier to work on in my opinion. Nothing we do is harder than we make it. Using a timing light is basic and simple but not having to worry about it when trashing between rounds is a bonus in my opinion. We've thrashed and had to change intake gaskets and we've changed lifters too in the staging lanes. To me, the extra cost is worth the few steps it saves you over the long run.

You can't please everyone and if every time a customer came into the shop, we disagreed, argued or refused to do it, it wouldn't take long before we didn't have any more customers.

The op wants a crank trigger, let's make it happen.

All this banter over why or why not is kind of selfish and pointless.

Just my .02 anyway.

(I type slow, this was before you updated your post just now Ed)

What Tom wrote is correct, and I agree that there is No maximum performance difference between either trigger system.

Last year I installed a crank trigger and did not purchase a spare sensor because my distributor trigger is my back-up.

The reason I installed the crank trigger was for a more accurate ignition control. With the distributor trigger I was unable to have Grid properly execute as programmed a 33 rpm window when having 4 Step Retards all activated at the same time.

I picked up nearly half a second and 12 mph by switching to a crank trigger and now I'm much more confident approaching women and all of my clothes fit better.

I like cherry vanilla and maybe you like chocolate ice cream...


Both of us are happy when we are eating it I am sure....

If my NON crank trigger equipped engine/car beats your crank trigger equipped engine/car, I won't rub it in......unless I have maybe 2-3 beers and the subject comes up and then I will......LOL Laughing Hard

Billy I just ordered a crank trigger....

If it works half as well for me as you, I will be happy...... Me too

Because you have Grid, you can use the ignition In/Out data acquisition to help quickly troubleshoot if your problem is possibly ignition related. Not saying it’s 100% but it’s much better than nothing when eliminating what might be the cause of a problem.
