Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

The surface area measurement includes both sides of the plate. A 10cm by 10 cm piece would do the job for two modules (that's 200 square cm surface area for two modules). But it needs to be able to sit flat against the module to ensure proper heat transfer. The aluminum piece you have looks much big...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

Thanks for the calrification.

And yes, if one already has working spares, that's the way to go for cost and time-spent.

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

For Pinhead: I was wondering if you had a condensed synopsis of the Ford regulator... Years, models, connection diagram or text... If it works I may have a use for it on a Kawasaki. I have a regulator/rectifier thread going in another forum and we're looking for cheap alternatives for Field-Coil reg...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

Pinhead: My 11:1 rebuilt engine with etched valves and intakes under WOT has spark scatter at .8 gap. Loudhvx: Damn, boy, I didn't design it for your ass! Volker_P: I think stock is nice, why don't you guys try it sometime? I'm confused by this post, totally. If people want to keep their bike total...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

Hi Lou, I didn't mean to be disparaging in anyway. I admire your technique and what you have done, but then this thread would be off limits to you as a critic and a cynic then, wouldn't it? Unless you have total allegiance to Honda, or some great memory that makes it all worth while, or a certain p...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

And Lou, I just had a brainstorm. What if you said "Permanent Negative Bias" and "Temporary Positive Bias?" Well, they are both positive bias, but yes, one is permanent and one is temporary. One is applied to both from one power source, and the other is applied to each independe...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

Yeah, on mine there is usually a ball bearing or two that flying as well. That type of work needs to be done in an empty, all-white room... preferably padded. :lol:

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

On the 7 pin version, the resistor and diode are for biasing the negative side of the pickups permanently. On the 4 pin version, the resistors and diodes are for introducing a temporary, small, positive voltage to supplement the pickup signal. I guess, it could be said, it is biasing the positive si...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

Ok, now I'm confused. :( What's confusing me is the "(int) Harness" and "(Ext) Harness". I guess not having a CB, I'm lost on the whole "blue tube" and "yellow tube". Why are the colors flip-flopped? (I realize that may be a question for Honda :) ) Grounding: ...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

In order to properly measure the resistance of an item, the default method is to remove the item from any other circuitry in order to isolate the item. In special circumstances, you can leave the item in the circuit, and still get a reasonably accurate resistance reading, but if the rest of the circ...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

Considering doing this upgrade, but wondering how long those of you who have done it have run with it. i.e. 6 months no problems, 30 years no problems and so on. A little paranoid about electrical bits and old Honda CB wiring...apologies. Thanks for the fantastic thread! I have about 6 years on the...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

When measuring the "G" terminal pickup for ohms to select the resistor needed, is it measured to the ground of the module? And since there are two does each need to be matched to the appropriate resistor if they measure differently? . The first thing to do is simply measure the resistance...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

.2mm gap seems close to me. I think, under high stress, the crank can wobble that much.

But if you never see any wear marks on the rotor or pickup, then I guess it's ok. I designed around .6mm, but .2 or .3 should probably work fine... just estimating here, though.
