Mag 20 versus Mag 44

What are most of the alcohol guys running? A 20 or a 44 Mag?

I've been told that a fresh 20 is more than adequate for any alcohol racing, and that running a 44 simply makes a rich man poor by quickly burning up coil wires, caps, and plug wires.

Is this true, or am I getting my wire tugged?

Thanks.

 

We ran a 12 and 20 for 4 years and found no diff between the two, we went low 5 80,s. With the 44 we were able to take 6 OR 7 degrees out of it and it runs the same but much smoother! and the motor is much happier.
We put 40 runs on a set of wires last year. (MDS wires)
Your getting tugged!

I would go 44 for sure!

 

Nice thing about the 44 is that it is a no question part. It works and you don't have to worry about it. Not like the days of the mallory mags where guys bought coils by the dozen and changed them everytime the car shook. I change my coil wire every 5 or 10 runs but that is about it.

 

Per MSD

Per MSD engineer
The 20's were originally made for the Alcohol guys. Some then the guys started running 2 of them. From there they switched to a single 44, To cover them when their tune up was off.
If your tune-up is correct a 12 will work and you will not gain performance from a 44.

 

The reason for changing the coil wire a couple of times during the season is that it is usually out there flopping in the wind. When it fails it is more than likely at next to a terminal where the wind is tuging on it. The guy who told you it would burn up wires, rotor, and cap must have caused the problem.
If you run a crank trigger and the generator is not in phase the spark is so intense that it will eat away at the side of the rotor and tip. that is the only thing that has ever hapened to me. With the blower is overdriven a bunch which results with high dynamic compression I would go for the 44. If you are not planning on making a lot of power just about anything will work.

 

The coil wire fires 8 times more often than the individual cylinder wires. Theoretically it should be used up eight times faster than the other wires. Maybe it does flop in the wind but not so much in a funny car. Dave Germain

 

I race a promod boat with a 547 chev. dart big m,1471 hi helix.I am currently using a mallory mag 4.I am curiose if anyone knows if a csi gear reduction starter will spin the motor fast enough to light with a mag 20 or 44. I have been real happy with the mallory but,people keep telling me I need to switch to msd.When using msd how do you get from a mag signal to rpm signal.My trans is shifted by rpm.Any opinions are greatly appreciated.

The guy to ask is Serge, Dan Mercer ran a Grand prix boat that had an alum. chevy in it pretty much like yours, I notacid they ran a very small flyweel, and i think that it made the motor spin faster on the starter.

 

Starter

You Will Probably Need A 16 Volt With That Csi Starter. Mine Wouldnt Start On 12, Or Even On 16 If The Battery Was Weak

 

Order MSD-8132 to convert mag rpm signal to std rpm signal

go with the MSD... you'll love it. always works... very reliable. change the coil wire frequently and you'll have no problems. the energy eats the insulation from the inside out and they start acting goofy. and like germain said this happens to the coil wire 8x as fast. they will look ok... ohm ok... but they will sure jack with things and often do completely unexplainable things. so anytime you run into an unexplained gremlin... change the wires first. it's a cheap diagnosing tool.

BUT as for your real question... you will definitely need to spin it fast. not sure what you can/can't do in a boat... but we just hit the starter (tilton) with 24v from two batteries wired in series. we have an onboard starter but plug in the batteries. 12v will not start it... neither will 16v if the battery is tired at all. best of luck... sean

Yes , we ran some PRO-MAG 44 in our Hydroplane Engine without any Starting problem but be aware to have the right Battery set-up , 16 Volt Battery minimum , Good cable and your fuel system already prime up. The CSI Starter will do the Job , have a spare one in the trailer.

Our engine combo was a 510 BBC with 10.5 CR , Dart Big Chief Heads and Kobelco Superman 14-71 HH Supercharger at between 20% to 30%. If your Mag is driven by a offset Drive at the stock location ( back of the intake manifold) be sure to have the best one , those PRO MAG are hard to spin.It was a trouble free unit for us and it was the way to go. Everything , Boat and Engine set-up are now DOWN UNDER in Australia.

Hope this help !!!! By the way ELI Who are you ??????

i run a chevy with a 44 mag and a csi starter and 2 batteries to get 24 volts .you'll have plenty of cranking power.

 

Hey Claude

Did you fire up that BAE engine yet ????

Serge TAD-11

 

Not yet Serge,
Everything is fitted on the car (mecanical ) , the fuel system is completed ; thanks . I presently works on electrical system , everything goes well . I will call you soon , i have couple of questions for you .

I just changed from a mallory 4 to a msd 20.We have a tilton starter with standard 12 volt system.We have had no problem starting the motor after the change.The mag is on a 8.5 comp,6-71,485cu in weadge on alky.I hope this helps.
