price for msd ignitin system

[Geezer]

One thing hotter coils won't do for you is stop the high-RPM break down of spark voltage. Just comparing spark voltages is not telling the whole story. With the MSD spark voltage will be constant throughout the RPM range and you will be able to run a larger sparkplug gap to get more fuel in the spark for better ignition.

I'd put this setup on my bikes too but the price is way more than I can justify. Fortunatly their auto units are more affordable and I put them on my cages as I can swing the funds. One of these did wonders for my old 240Z.

[bandet01]

so you would ran this setup if the funds were there and it aint going to be a waste of money

[Geezer]

Pretty much. Right now it would be very hard to justify spending a grand to upgrade the ignition on a bike that I'm in less than a grand.

What I'd probably do is to use 2 of the car units packed in where the airbox used to be and stay with the stock coils or maybe the coils from MikesXS.com. That would cost less than half of the set up you were thinking about and probably would work about as well.

Shop around the the MSD 6A (or the 6AL if you want a rev limiter) can be found at lower than list prices.

The bike units are made in very small quantites and therefor cost a bunch more.

Bandet, the Dyna coils (about $350)on my bike had this stamped on the box they came in.
-35000 volts output.
-improves overall performance.
-highest spark energy.
-road and race proven.
-extends sparkplug life.

They made the 4-1 exhaust give out a 'crackle' type sound when revving the motor up and down with an instant response. I widened the plug gaps to .40. The ignition fires to life at the merest touch of the starter button, even in mid-winter. The motor howls and screams from 5000 to 8500 revs with no hesitation. Whether they'd gain 0.3 of a second over stock coils in a 1/4 drag - well, very hard to tell. I don't think they actually boost raw horsepower on a machine.

Hey Pggg,

I don't think they actually boost raw horsepower on a machine.

How can you say that?? The 'hype' from MSD is that the stronger and longer duration of their spark pulses cause more complete combustion which translates into more engine power cause you're getting more work out of the same amount of fuel/air mix than you normally would with OEM ignition.

So...I would think, and have experienced that even with just new spark plugs, that an engine seemed to start quicker, and ran stronger than with the old plugs. So...I would expect that with a stronger coil giving a stronger longer lasting spark that you would experience more complete combustion and a stronger explosion effect which would translate into more power!!

But like Geezer said, it's way too much money to spend on one of these bikes for the small amount of performance gain one can probably expect from it. Still think just putting in some stronger coils would be the better results for $$ ratio option! JM2cents!

Here's my example from 'real world' results. My first XS11 was a standard 78E, 1102 cc, rejetted with 4-1. Top speed laying flat on the tank was 202 kph. Consistently. I wired on brand new Dyna coils. Top speed flat on the tank was then 202 kph. Consistently. My conclusion was horsepower did not increase.

.. hey but wouldn't that 2 step sound bitchin wound up to 5 grand at the starting line!. and you would get some awsome launches
,, after you learn how to use it i think your times would improve considerably..
.. i think the hotter spark would improve on your low end response, on take off is where you need/notice it the most, but over all not much help on the big end .. the more performance improvements you make to your bike, the more this ignition setup will help you
.. the biggest benifit you will realise with the package at first will be the 2 step
.. next you will want an electronic shifter

With that spare thousand bucks Bandet has laying on the kitchen table, after the double MSD setup, he should unbolt the cylinder head and take it in for a port job. My port job cost about $600 if I remember right. Ported for 'street' - that is low and midrange. DEFINITE extra kick there.

[Pat Kelly]

I think you should buy the MSD and put it on your bike Bandet. It's your money and your bike.
Dyno the bike before and after and let us know the difference.
We've had the thread on the fuel injection and megasquirt set-up (was there any power/fuel milage conclusion with that?), the chain-drive conversion with follow-up report. Dyna and Accel coil upgrades (I did the Dyna coil tech-tip and my "seat-of-the-pants" conclusion is positive).
Why poo-poo Bandet for trying another avenue?
Gopherit dude!

[pggg]

Sure, go for it - no-one's poo-pooing anyone here. But it'll take more than a tiny spark on a sparkplug to boost power - you'd be looking at 1/4 of a horsepower - if that. But if the moneys no prob, then spendit

[bandet01]

i was just looking it to it for the fact i know how good msd products are and how reliable they are and was woundering how well it work but since nobody has tried it yet i spose i will be the ginny pig on trying it, there are a couple reasons i wanted to go this route is because i do plan on adding more horsepower parts and was thinking with this setup i know all the fuel is getting burned and the spark is not getting blown out.

i mean i plan on a big bore kit later on
a 4 into 1 exhaust
get the carbs tuned
and a new clutch and spring to hold the extra power

i mean i dont plan on getting rid of the bike anytime soon since there aint no new bikes made that i really like , like i like my xs1100

[LoserShoes]

The high buck spark systems don't really start to be effective until you do things to the motor that increases the cylinder pressures at TDC, such as compression ratios, porting, tuned exhaust, radical cams, blowers .
It's the high cylinders pressures that put out the spark.

[bandet01]

yes i know this but i plan on going with a big bore kit and cams and a 4 into 1 header exhaust setup so i want to make sure i have enought fire so it dont get blown out

[pggg]

A.P.E. do twin plug conversions for what seems a reasonable price. The beefed up MSD ignition would be the 'bees knees' then.

[bandet01]

what info do you have on the twin plug conversion and i am just plan on putting this bike into the high 11s maybe faster just depends on how fun it is to run 11s
