MSD Coil Blaster 2 - I am not blasted
Hi,
I just got this MSD Blaser 2 Coil for my stock TI-System.
But before use I measured it and compared with an old Delco coil.
MSD primary: 1ohm secondary: 5k ohms.
Delco primary: 0,8ohms secondary: 15k ohms.
So it seems the Delco has 3 times more windings on the sencondary, or the MSD has a much wider wire diameter.
Made a test on the Bench, applied 13V and the Delco makes a much stronger spark than the MSD does.
Are Im wrong, and only using it on the engine will show the real qualities, or does the advertising lie where they talk from much more power?
I could imagine this thing is just optimized for usage with the 6AL box, where the go on primary with 200V.

The stock TI coil, compared to a stock point coil is in the same league as the "Blaster" coil.
If you try running a TI coil in a point system, it will burn the points in a very short time.
If the MSD Blaster coil is intended to function in a point system, then I would say that your original TI coil is a better coil and will give a better spark.
The TI Amplifier is able to handle the low resistance on the primary of the TI coil and therefore provide a good hot spark.
In my opinion you would not gain anything by installing the MSD coil in a TI system.

So more length = more resistance.
@Barry:
Did not know that there are differences between point and TI coils.
The TI uses a resistance (wire) before the coil as well.
I will check what I currently have on the engine, had put a new stock coil on it just because the old one looked very used.

The ohmeter won't tell you anything about what's in the coil. The Ignition sticky above will explain why.
FYI: The TI coil is made with a higher secondary to primary turns ratio (or lower primary to secondary ratio) than the points application coil. This was necessary to keep the primary voltage "lower" during ignition (ie: plug firing) to keep from blowing up the original germanium switching transistor and zener protection diode. Using a coil with the wrong turns ratio can burn up the module. Unless the aftermarket manufacturer tells you the specs of the coil you want to use with your TI system you're gambling with the reliability of your system.

What I meant to say was, that in order for the MSD coil to provide higher output, it seems your numbers would need to be reversed, ie the MSD coil should have more secondary turns and thus a higher turns ratio. If that's not the case I don't see how it could provide a higher voltage spark than the Delco unit unless choice of coil material or design provides for more magnetic saturation and a stronger collapsing field to be transformed to the secondary side.

69427, I just readed some posts from you in another forum, found with google ;-)
You seem to be an expert!
I could not wait, its 1:00 AM here, but I went into the garage and disassembled the coil I had mounted 1 year ago.
Primary: 1,5ohms Secondary 10k ohms.
So this must be a points coil.
Ok, I will put the old original coil into the car. (Have had missfire at high rpm, this was solved with other sparkplugs, but i wanted to do something more with a stronger coil)
And so it seems i have just wasted the money for 2 coils that do not belong into my car. And I need a 4th one as replacement. Where can i get TI coils? Are there slightly stronger versions available?

Found one at CA, looks like mine, and of course its the expensivest of all coils with $145 
GM Type 263
And Paragon has the similar type 207 for $65.
This type 207 is the one I have here.
Does someone know the differences?
And paragon claims this here
https://www.paragoncorvette.com/p-36...coil-w-ti.aspx
and this
https://www.paragoncorvette.com/p-36...coil-w-ti.aspx
would bring more power with the TI ignition.

Some trivia on TI Ignition...........
Two years ago my TI Ignition failed, hot day, 60 miles from home.
It was the "pick-up" coil in the distributor.
While I was waiting for parts, I installed a point dist., and point coil, so I could still drive.
With the point setup, I could not rev higher than 5K due to serious misfires and popping.
Points were new, coil was unknown.
When I reinstalled the TI setup, revs to 6,500 were no problem. Don't discount the stock TI system, they do work well for being a 50 year old design.
( I did upgrade the TI amp module to the solid state one, although the transistor board was still working fine. They do fail, so it was just a matter of time)

I'm still running the original TI in my 69. I tried a Mallory box. IT ran- hard to start, fell flat at 4500. Only thing I gained was the rev limiter- but I couldn't get enough RPM to hit the set point. Back to the TI.

The msd blaster coil is nothing more than a made in china coil with big name marketing make all the HP "gains".... all oil filled coils are now made in china... or to quote MSD " there are no longer any manufactuers making oil filled coils in the us"..... they do attempt to rebrand american made coils as their own whenever possible it seems but you can't expect them to manufacter their own? That would be ridiculous in today's day and age... when it comes to coils they are usually made on the same assy line and the ones that "test " better are likely sold as performance coils
