I do currently have a NIB(new in box) MSD Blaster 2 coil, but my wires and CDI(Compasitive Discharge Ignition) might be at a level past this. MY question is which coil is rated for Compasitive Discharge, and will provide the most electricity to the plug.

My ignition currently is as stated-
-Accell Billetec HEI distributor
-Mallory Hyfire VIa
-MSD Super Conductor Wires 8.5mm
-MSD Blaster 2 Coil(under discussion)
-AC Delco R42TS Plus(might have to change heat rating)

 

What type of ignition system are you using/? An MSD box or the factory HEI?



FWIW here's my setup. Just a stand alone ingntion system. No computer control, HEI or anything:
I use the MSD Blaster SS #8207 with a 6AL, 8551 distributor and Moroso wires. Also NGK 9 plugs. Turns to 6500 no problem.

 

MSD 6 series ignitions are far outdated. They are analog, use way too much energy, and loose the benefit over having the excess spark.

Nerwer ignitions like Acccell 300+, Jacobs Digital Ignitionds, Crane Fireball, and like me, the Mallory 6 Series Ignitions. These newer digital ignitions, not only are more reliable, they put out more spark energy because the unit itself uses half the energy the analog units do. Digital units do not put out near as much radio noise, and are much more heat and vibration resistant.

So in semation, i would not use a 6a or 6al box. I use a Mallory Hyfire VIa(6a) box.


I want a coil to provide powerful spark into the 7k rpm range. From what i've read Blast 2, and the SS drop off start dropping at around 3k-3500, Accell super Coil start dropping at 2500-2800.

 

You make good points, but for what I and most people on this forum are doing, the 6 series works great. You could always go with what I use on the dyno which is a 7al2 and a HVC 2 coil. You can weld with that thing

 

which coil is the HVC coil you speak of, not familiar with that abreviation....

 

MSD 8261

Puts out 2 full amps

For use only with the 7 series. They make one for the 6 series too but not as hot.

 

Thanks just placed my order for that coil 2 amps is tremendous, i dont see why it cant work with the ignition i am using, i'll find out if it cant but this will be one stout as hell ignition.

 

Cool deal. Let me know how it goes !

 

i mean seriously, 45k volts @ 2 amps will kill someone. If i get shocked by my ignition its like one of those things they shock you with at the hospital, it can mess up my heart rithom, or just plain kill me.

But besides it being able to kill me, it can seriously make an ignition worth bragging about.

Summit shipped it today so it should be here pretty soon, cant wait....

 

I got hit with my 800ma Blaster SS and it put me on my a@@. Ii'm always real careful not to get bitten my the HVC on the dyno

 

I asked a guy at a local dyno shop, and well he used the exact same coil. Said an old employee got hit by the HVC coil, and well, he is on government disability now. He said he can barely walk at this point. He got hit 2 years ago.


For me that means my ignition will burn through anything that tries to foul my plugs.

 

How exactly is an analog capacitive dischage ignotion 'outdated'? And how exatly do you equate the output rating to preventing plug fouling? Damn wish I lived in that world!

 

Try the crane cams fireball coil. It puts out more than MSD (Pun intended ).

however I would highly recomend Crane Hi-6 igntion. Much better than MSD construction and reliability!

 

Simply because plugs get fouled because they cannot ignite the fuel, or reminace of that in which on fire. An MSd ignition can burn though anything left on the plug may it be oil or anything. Hell the ignition eats away the plug. I'd dare oil to try to stop it.

And out dated analog ignitions are out dated. When was the last time anything analog was co nsidered modern if there was a digital solution? i'm sorry but the answer is NEVER!

 

Oh my, NEVER is a long time.
I have played with both analog and digital circuits and trust me, never say never. The audio nuts will argue this till well past midnight.

I use the Crane Fireball 6 with a Crane LX42 coil, plugs set at .045. I have not done a hand VA test yet, I'll give that a miss. Ignition under hood no audio problems. Had a MSD 6AL on a hotrod (FRG) and had lots of noise.

 

Check this page out.Crane vs. MSD

 

1. You apparently don't know exactly how it works.

2. You apparently never had to work on a monster motor throwing out insane RFI.

There is a place for everything and there are situations that require certain things, try and refrain from spreading your ignorance around.



As for the crane comparison, I'll take hand soldered wires over robotic surface soldered ones in the Crane. Just like in a cell phone. Just for that I'll go with another digital set-up over theirs.

 

easy to explain why the ignition eats away at the plug itself. electrical erosion. it is mainly the the way the METAL reacts to the electrical current that flows through it. happens to most metals more often then not on the positive side of the contact. doesn't have anything to do with oil or other crud though as it effects the metal.

as far as anolog being outdated. thats fine but trying telling that to people who do music. more often then not digital might be nice and ok but for myself give me those old outdated tubes. screw the digital stuff or even anolog semi conductor stuff.
newer and modern doesn't always mean better

 

just cause the coil is rated at 2amps peak current doesn't mean it is putting out 2 amps. there are a lot more factors involed in this then just that.

 

well a col rated at .75 peak amps, is going to put out less then a coil rated at 2 full amps peak.

 

just because they rate the peak amp rating at that much doesn't mean it is giong to put out more current.

or that it is going ot put out more current then one rated at a lower amperage.



as I said think I said before there are a lot of other things going on then just the peak rating of the coil

 

i understand all the other factors involved in a coil.

yet 2amps peak or rms, is always gonna be higher then .75amps peak or rms. With your argument its like saying a magneto wont put out its rated amps, but ummm.... sorry it does.

If these things need to be cooled off, i already am mounting them in a vented box, just add fans and they will be a-ok....

 

here is one big one for you as to one might have a higher peak rating.

thickness of the wire.

if both still have the same inductance, turn ratio primary and secondary resistance, but one just has a little thicker wire that might allow it to have a higher peak rating as it allows the wire to resist the heat better.

same thing with how the coil is cooled that could make a difference as well.




but since you understand all the factors involved in a coil could explain a few things to me

what is inductance and how does it effect the coil. how does primary and secondary impedance effect the coil, what does the turn ratio do, what about wire diameter, what type of transformer is a coil? I'll give you two options either autotransformer or isolation transformer and how would that effect coil operation?


sorry but your history here with ignition post make me question some of the things you say.

like spark plugs have no resistance, wire resistance makes a big difference in the ignition, things like digital is ALWAYS better and analog can NEVER be better.

 

Dave Ray, AKA IgnitionMan AKA The Proffer
[mod at BuickThunder, with his own section]

was an engineer for GM, who designed ignitions systems..........

oil filled coil are the only way to go. He still builds systems for many race teams and does small body conversions [ small body dis, not small body cars] . The epoxy filled ones hold in to much heat and will fail you in the hi rpm band when lest expected.

Epoxy filled may look neater but there is a reason they made them coils like a beer can and filled it with oil, cooling.

plus most stuff is made in out of US junk.

a quote from one of his post.


"I'd use the NAPA IC12 black coil, or one with a primary resistance of 1.50 ohms, NOT the 0.70 ohm Summit. They will tell you that their 17 coil is the same as their G5215 chrome coil that actually has 1.50 ohms, and IS made on the same line that the MSD chrome 8200 Blasters are made on in Andover, Indiana, USA. That's what they will tell you, and it would be wrong.

I'd also stay away from MSD Blaster II (8202, 8203 Mexico made by Pro-Bobbin), Accel (all Accel are now made in Taiwan, problem prone), any and all epoxy filled coils. "

well ok, i guess my electronics classes in highschool are now coming to use. hehe.

inductance as i understand is how well an electric circuit induces the current. So if a coil had better inductance, it is an area the electricity would want to go.

the havn't yet quite gotton impedance stuff.

Turn ratio much like electric motors is simple. the more turns the longer it takes to fully load all energy, but more energy is stored in one single turn.

wire diameter is for current, larger diameter more energy can flow through, thinner diameter, more energy can be stored in the coil due to a longer strand.

and duh an ignition coil is an autotransformer. Basically, if its an isolation coil the primary and secondaryies are apart, therefor completely separate which help limit impedance. oohhhh i remeber this **** now. haha. autotransformers suffer from impedance because they are in a common wind. more impedance is a bad thing, much like car stereo systems. Less impedance is less obstruction to actual differnt jobs both coils play.

Sorry but i did have to get my old electronics book out of the dust and cheat a couple times, but i had ta. I have a good understanding, just not the means to explain it.

 

little hit and miss but ok I guess. either way not here to argue that stuff.


the point stands just because it is a 2amp peak current doesn't mean it is going to be putting out more current then a .85amp one. digital ignition doesn't always mean better. for that matter digital sometimes isn't better even though you claim otherwise. spark plugs do have a resistance to them. they have had them for quite some time. spark plug wire resistance isn't going to gain much in the form of electrical energy being it is a very small part of the whole ignition system. like removing one bolt of your car and saying " wow I just did some weight loss I should be faster now"

 

Not really trying to fuel the fire hear but can someone explain why a digital ignition is better (or not) other than just saying so. Other than the wow factor & some extra bells & whistle what's the big deal with digital? Inquirering minds want to know!

 

Has anyone tried the MSD 8226 coil? Ext coil HEI, 2 connectors. I may need a new coil, currently running the original stock coil, and I'm having problems.

 

for one digital uses less current, i have been in some cars that had an msd box, and when at a low idle everything starts to dim because of the immesnce current draw. Digital doesn't draw near as much current to fuel the device, mostly the energy needed for the outcome.

digital also runs cooler, because less current.

digital, in most aspects, here especially, digital is more reliable, and longer lasting.

ut with digital circuits they are subject to interference alot more.


which with audio is the analog plus, they are not subject to electrical noise as much, and sound quality remains the same.

 

sound quality I will at least chop up to opinion but when I'm playing guitar digital isn't for me. I can handle some transistor stuff. it's not the greatest but it works. tube is the good stuff more often then not. those old fasion tubes

even when listening to music those old fasion tubes that have so much distortion to them and aren't as clean as digital or analog circuits tend to be a little better in my opinion.

 

LOL! My man! I refuse to use transistor amplifiers or those new computer modeling amps, they sound like CRAP. I have 6 old tube Fenders, some dating back to the 50s and 60s, and they sound fantastic. In fact my main gigging amp is a 1964 Deluxe Reverb. Yep for musical instrument reproduction, give me old vacuum tubes.

 

but but AAAAAAHHHHH they are distorted even when clean no no pure digital should be the best as it should be the least distorted right. also digital should be best being it is more efficient... no no you speak evil

 

digital is more efficient, is consumes less power, and distorts the signal less.

however in music, distortion is a good thing. Speakers microphones work better with distortion.

its like a HDTV compared to old fation CRT tv's. digital is better, it uses less electricity, and so on, but the fact still remains, CRT's are coming back, and in a big boom becuase they are analog, and converting a analog signal to digital causes distortion, another reason digital stereo eqipment is bad.

And the old thing the FCC made about all channels going digital by 2007, is gone, they cannot force this on anyone.

 

A little bit of distortion might be a good thing, if it's even order harmonic distortion. The big difference is when you drive the hell out of the amp and it starts clipping. Bigtime distortion, the sound of rick and blues. Tube amps have a much smoother distortion than harsh transistor amps.

The computer digital modeling amps that are on the market today just don't sound right, and they get lost on stage in the band mix.

A 20 Watt tube Deluxe Reverb is loud enough to make you wince, the guitar speakers are FAR more efficient than the crap used in car stereos. Like 10 dB more efficient. Check out these speakers www.tedweber.com . Great stuff they sound fantastic.

But what does this have to do with ignition coils? We digress....
