Re: Crank Trigger
 

Now I am confused...I did it for the same reason and ended with an airplane! :)

Re: Crank Trigger
 

Wow! Tough crowd. I ain't an engineer, nor an electrical genius, but I know a crank trigger is more accurate then a distributor. I have never ran a back to back test to see if one is quicker, I just know one is more stable. Will he pick up if he changes to one? I truly don't know.

Re: Crank Trigger
 

Yes he was. I for one wish they would take him back so he would leave here and quit ruining threads like he has done to this one.

Re: Crank Trigger
 

It would be one thing if it were just this one...but unfortunately it's a long string of threads...:(

Re: Crank Trigger
 

For those that took the short bus to school, the op speciafically asked...

and that question has been answer honestly and accurately by myself and others...
More stable timing on these engines at the RPM they turn and the power they make does NOT result in quicker ETs that can be seen on a time slip and deteremined to be the result of a swap from a locked out billet distributor to a crank trigger.

Now what the op or anyone else decides to run/spend their coin is of no concern to me, I'll continue to spend my coin on parts that I KNOW produces quicker ETs on the time slip, NOT the trick of the week and parts whose reputation is founded in myth, rumor, hearsay and marketing!

It's for this reason why my cars always run quicker ETs as well quicker 60 foots than similar cars at similar weight despite them having more cubes and bigger everything!:p

The truth and the facts are just that.

To the op, my apologies for the nonsense and stupidity that some feel necessary to post, rather than reply to your question.

Re: Crank Trigger
 

Way to edit the question Ed...read it again. Pros and cans...is one better. Damn you'd think being an engineer would require being able to understand english unless of course it's not your native language. As usual you've misrepresented even the question to suit you. For your info a crank trigger is NOT "the trick of the week" been around a few days, what rock have you been under? Definately couldn't have a bigger EGO than you. Since you don't run one how can you state there is no gain? again simply your opinion, having absolute control over what the engine is getting for spark and fuel is how one MAKES POWER prolly why you make around 1.5 percube. Yes the OP's question has been answered....there are no cons using a crank trigger (unless your rules don't allow it) given the choice go with what provides the most stable triggering events...directly off the crank.

Re: Crank Trigger
 

more CLUELESS comments from one that thinks he knows!

1.82HP per cube!:p

Re: Crank Trigger
 

BTW Ed ignorance is having no knowledge of something...stupidity is having no knowledge but stating that you do or knowing better and doing it anyway. Sound about right? Making claims like you have without knowledge of the subject (you don't run a crank trigger so you don't actually have any REAL experience or data to back your claim) IS simply stupidity. My sons car with a STOCK 460 (with the exception of the cam shaft, bone stock heads and a dual plane intake on a 10 inch slick regularly runs 10 teens, much quicker than similar cars with much bigger engines. Does it make him special....no merely a good combo. So if he were to come on here glorifying himself as gods gift to drag racers, he'd be as full of it as you are. Still waiting for your reply of a second opinion that a dist. based ignition is as good as a crank trigger.

Re: Crank Trigger
 

Wonder what it is like to be SO impressed with your car and yourself?

Re: Crank Trigger
 

You could always ask Kyle

Re: Crank Trigger
 

Is Kyle banned again??? :) Have not seen anything lately.

Re: Crank Trigger
 

Yep. LOL

He was, don't know if still is.

Re: Crank Trigger
 

I figured that would flush him out for sure. Maybe he's grounded at home too.

Re: Crank Trigger
 

If Kyle responds to him, he might get banned for life! :)

Re: Crank Trigger
 

To js72mav, I whole heartedly apologise to you for any posts I've made that took away from answering you questions. I hope you can read the replies that pertain to your query and make a sound judgement as to the merits of each of the triggering methods you've described. Again my apologies. Joe

Re: Crank Trigger
 

Joe, you have compelled me to contribute something "on topic" for js72mav to consider while making his ignition choices.

I can easily come up with a dozen solid reasons to pick the crank trigger over a distributer ignition but consistency is one that applies to all racing types. The timing is constantly changing with a distributer type as already noted but even more than you might expect as oil viscosity or engine oil temp changes. Additionally, distributer drive component wear necessitates constant monitoring of timing throughout the season not to mention that slippery chrome clamp (never use one) letting things adjust themselves at the most inopportune times.

But I suppose if you're the kind of racer that's always holding a tenth, I guess consitency is overrated.

TP

Re: Crank Trigger
 

well I and everyone of my closest racing friends, some of which are stock and super stock racers must be the luckiest MFers to ever drive a race car cause our bracket cars are DEADLY consistent, our timing doesn't change with oil viscosity and temp:rolleyes: nor do our distributors require constant monitoring throughout the season for fear of component wear:rolleyes: not to mention the distributor hold down clamp allows "things adjust themselves":rolleyes:

CLUELESS comments doesn't close to describing this level of nonsense!

Re: Crank Trigger
 

You have experience with two cars. Tracy builds race engines. Possibly he has seen things you have not?

I hope you never develop the rotator cuff problems I have, you would not be able to reach back there and pat yourself on the back the way you always do. Congrats!

Re: Crank Trigger
 

Of course I wasn't refering to your perfect *****. You got it goin on trophy boy.

Re: Crank Trigger
 

I think his hands spend a considerable amount of time in front stroking..... his keyboard

Re: Crank Trigger
 

You are the clown prince of clueless, run off of at least 2-3 forums.

When you can make 1.89HP per cubic inch with a legal Super Stock engine, that you built, let us know.

Re: Crank Trigger
 

I have the iggy button pressed on him but everytime you quote him I can read it.
My feelings are that if a distributor ignition thats working perfectly is probably as powerful as a crank trigger setup. (If the fire is lit right it's as good as it gets) . A distributor is going to retard some due to chain stretch etc. This might be what the motor wants.
But with a crank trigger setup you can control exactly what happens and when it happens
That to me is a winning situation.

And I build my own engines, in superstock. But I only make 1.70 horses per inch...
Oh wait a minute thats at the wheels, through an automatic trans.
A 2600 pound car that can go 12.40's with an N/A 4 cylinder automatic.

Re: Crank Trigger
 

I notice your Stock / Super Stock "friends" don't seem to get on here and back you. What's up with that?

Re: Crank Trigger
 

I use a crank trigger because it gives me a " warm fuzzy " feeling.
I do like its rock steady state though.

Re: Crank Trigger
 

Thanks for the feedback guys. I understand what you guys are saying and agree. I just wanted to make sure I was thinking right. Right now I just have a locked out billet dist. but I am going to put on the crank trigger. I was just curious about if there is any actual horsepower gain or just stability in the timing. Thanks again!!!!!!!

Jamie S.

Re: Crank Trigger
 

I put one on the SS 396, and saw a considerable improvement in timing stability and some small improvement in performance, and we already had the best state of the art distributor based system MSD has.

Re: Crank Trigger
 

Jamie, you made your decision about your car and your money, good for you. Me, I must be doing something wrong when a guy with a mid 11 second car is convinced based on the opinions he reads on an internet forum that the addition of a crank trigger will reward him with quicker and or faster MPH on the time slip due to "more stable, rocky steady" timing yet I've got about 4000 10 second time slips, 1000 9.0x time slips and numerous 8 second time slips from two BBC combos with billet distributors that every time I've set the timing it too is steady at RPM. Further, the clamp has never loosened, the timing has never changed due to oil viscosity and temp and never in over 2 decades have I had to constantly monitor a distributor for fear of component wear but wait, it gets more crazy...the MSD billet distributor in my 950HP BBC has ~ 18 degrees of mechanical advance in it. Yep, you read right, it is NOT locked out yet somehow, I'm able to make pass after pass after pass where my 60 foots and ETs typically vary thousanths(.00x) on any given day. Guess I'm just lucky or maybe all this talk about more stable timing means NOTHING on the time slip with engines like yours and mine.;)

Again, Jamie, your car, your money, your time, your decision.

Re: Crank Trigger
 

Hey 1320, turn off your computer and turn on your TV! "Pinks" is on again.

Re: Crank Trigger
 

Ed , are you quoting ME? I never said I put one on because I thought it'd run quicker.
I did imply there was some timing variation ,although insignificant...............I just put one on because , well , because..........LOL

Re: Crank Trigger
 

I wasn't going to join this but I figured I would stick in my 2 cents. I had a problem with with my engine in the begining of my race season with a high speed miss above 6500. I chased the normal things, but wound up with a cam profile issue that caused destabilization in the valvetrain above the rpm stated above rpm. After a cam change my problem was solved. One of the conditions that was resolved was the timing jumping around while trying to set it. My issue is a small base circle cast cam core that was flexing with the aggressive lobe. The new cam had a different lobe and a slightly bigger base circle and cam core. I figure my cam was flexing and this was the reason for the timing variation.
I can see benifets to a crank trigger, when you are running very aggressive roller cams with alot of spring pressure causing cam flex in certain circumstances, and timing variation. With a crank trigger you eleminate a few parts that can cause an issue, nothing is more accurate than taking a signal off of the crankshaft. If you have a big enough cam core, and the right lobe design for what your trying to do, I'm sure a distributor will work well. I'm not really sure you will any ET in one over a good distributor. But I'm sure it won't slow you down. Your mileage may varry. Good luck.

Re: Crank Trigger
 

Leave your distributor installed ready to go after setting up the crank trigger. It will serve as a backup.

Re: Crank Trigger
 

Finally! you made some accurate statements, you are in fact "doing something wrong" when you flat out state that a dist. based trigger system is as good as a crank trigger. However I'm left to assume you're running a belt drive oil pump since you've stated you've never had a worn dist gear with "thousands" of runs....well you must have one of those unobtainium gears. The mere fact that you run advance in your dist. means nada, who cares but why unless you street drive it. I've not read one post where anyone stated they saw a gain in E.T. or MPH, so why do you insist on flapping your gums about that? Nearly everyone that replied (you being the one and only exception) simply stated they saw an increase in timing stability or stated their engine "seemed" to run better. Your statement that increased stability in the timing is the same as stating valve train stability is unimportant, which indicates a total lack of knowledge in the matter.Please refrain from further discussion on this matter unless of course you can supply a credible second source for your argument.

Re: Crank Trigger
 

funny that the masterbater aka tech claims his skill set allows him to be able to "diagnose and repair modern vehicles" but is clueless, no surprise, as to why I run mechanical advance in my distributor. His guess is because he thinks I drive my MPR built Super Stock car on the street.:rolleyes:

WRONG, care to try again?

Re: Crank Trigger
 

Oh Ed, first and foremost you do not posses a "super stock" car you merely have a possibly legal car with a bracket motor.....so you have a BRACKET CAR period! BTW I drive an F1 car to work...minus of course a legal engine, chassis, ect...well it could be an F1 car right? Any "claims" I've made are easily backed up by the many certificates I've earned from the general motors technical college. Yes I'm a bit mystified by your desire to have advance in your timing though the reasoning behind it I don't care to know as it's of no benefit to me. Dump truck motors may indeed run exceptionally well with a bit of advance, not sure as I have an actual LEGAL super stock engine. So the next time your "modern vehicle" breaks down on ya, please inform me of how you got out with some tape and pliers and got er going again. Good luck. Oh and 1 more thing since you have all those "freinds" including what you say include stock and super stock racers why haven't any of them come to support you claims?

Re: Crank Trigger
 

too funny and WRONG, guess again!

Re: Crank Trigger
 

The only logical reason would be for easier cranking, but they make start retards for that....

Re: Crank Trigger
 

Since you flat out refuse to answer any question posed to you I'll leave you with 2 final thoughts...first I find it ironic you use the word "clueless" adressing others as it's spot on describing yourself. Second I'll be watching to observe any and all second party input on the matter that support your statement with just 1 fact or example to back it up.Again....good luck.

Re: Crank Trigger
 

Oh I think 1 retard in that car is enough.

Re: Crank Trigger
 

Anyone in particular in mind? :D

Re: Crank Trigger
 

Now thats funny for sure.
