MSD any one have any input on them??

[GstRacer]

well i bought the dis 2 high output part number 62113. and i was wondering what anyone has thought of msd? negative or positive and maybe where they put theres in the car. whats the input on gains. thanks a lot for any help or pictures or anything merry XMASS!!!

 

[andymoraitis]

You'll get a little more gap out of your plugs before blowing out the spark but that's about it. You can go 10's on a stock ignition and if my DIS-2 wasn't in the car when I bought it I never would have considered it as a future mod.

There's better things you can spend your money on.

Hope that helps,

Andy

thanks for the input but i have eveything except the msd. so i really have nothing eles to spend money on for motor stuff untill i decide to upgrade my 60-1 so i wanted to get evry bolt on part i can before i go with a bigger turbo. and msd is the last thing i can think of. but thanks anyone eles??

 

[chicagoavenger]

Pretty much a waste of money like it was said before

 

[GstRacer]

hmm well i dont know about a waste of money so are you saying Shep wasted his money?? but to one his own i guess . im pretty sure most race dsm's are not running a stock ignition. soo.......

When you're putting down 600 WHP, then consider an MSD. You asked for opinions and I gave you firsthand information as to why they're not necessary. It sounds like you just want someone to say it's a great investment because you already bought one.

I'll say it again. It's not necessary at your power levels. It's not even needed for what I run but since it was already installed on the car when I bought it, I left it in.

 

[GstRacer]

i undersatnd at what my power level is right now, but when i put on the 3075 now thats a diff story wouldnt you say?? considering i will be running race gas a lot. my cars not a daily driver either it's mostly just a fun street/race car with out taking race to the extreme ie cage and ripping out all interior ect. i have eveything in the car to make 600+ HP to the ground not with the 60-1 but with the Fp 3075 or even 3065. so i guess that what im talking about.

 

[GstRacer]

thanks a lot and no im not looking for someone to hold me hand and say good job. i just wanted to hear people that have an msd and say ya the car was so much smoother when i used the msd. or no diff witch i find to be impossible. but thanks for the input.

 

[andymoraitis]

Ah, if you're going big then it sounds like a decent investment. I just haven't noticed any tangible difference from having one. In fact I'd like to pull it and sell it.

 

[GstRacer]

well maybe you should just to see what its like with out it??

 

[andymoraitis]

Bah, all I'll have to do is close the plug gap up a little bit if I remove it. To me that's not something that's worth it since the stock coil packs are plenty powerful.

 

[Elvenhome21]

I am all for any type of msd box. Granted true cop with actual MSD coils and DIS 2 or 4 would be the ultimate in setups, but like andy said the stock coil will work fine.
But I disagree with his point on tighten the gap and it wont make a difference. An Msd box has a purpose and shouldn't be overlooked that easily.
It will prevent a lot of misfires along with more gap which means a little more power (probably only 5-10 hp at most) and also being able to run leaner without detenation. Plus the price isn't that bad and it looks nice where ever you mount it.

 

[andymoraitis]

I've not removed mine but I've bypassed it and at the same boost levels and tune all I needed to do was tighten the gap from .028 to .026 at 27 psi. While the larger gap is more efficient with respect to fuel burn I still don't consider it a big deal. It would be interesting to measure the difference on a load holding dyno however.

Nevertheless if you already bought one, have at it. It's not like it'll hurt.

Regarding the mounting points, I have mine in the glovebox and it stays cool and has worked without issue despite MSD's recommendations not to mount it there. I can open it in the middle of summer and it's still nowhere near as hot as the engine bay.

 

[Elvenhome21]

well on a chevy just indexing the electrodes alone is worth 3 hp, so an MSD box with that much boost has got to be at least 5hp, but even if not the misfire and running leaner has got to be worth quite a bit. I know i'm comparing apples to oranges but it a representation of what simple things can free up horsepower

 

[andymoraitis]

I think we're noth pretty much saying the same thing. If I didn't have it I wouldn't miss it but being able to open up the gap certainly has to help a bit. I'm sure that on a weaker ignition setup it would make a noticeable difference.

My friend Tony has a 2.3l full weight 2g with a GT40R and he is running 10.4@139 and he is on stock ignition, dsmlink and a 2g maf (using fake maf feature of dsmlink). So trust me, you don't need msd ignition anytime soon. Before the gt40r, he ran an fp3575 and maxed that out with stock ignition no problems.

Had MSD DIS 3 times, NEVER AGAIN

Go with a AEM UNIT

 

[Elvenhome21]

I am not saying the stock ignition is weak nor does MSD change the strength of the coils. All it does it makes multiple sparks whichs ignites all fuel, instead of one continous spark that doesn't always ignite all the fuel thats in the cylinder. My only reasoning behind cop is you get more saturation and dwell time in between spark and it isn't sharing spark with another cylinder which means more voltage, along with no plug wire which has resistance and the chance to arc. But the coils on a COP have to be good coils to begin with, such as actual MSD coils. Stock coils are virtually all around the same voltage but once you upgrade to an aftermarcket Accel, MSD, Mallory you instantly get 5-10,000 more volts instantly.

Again I AM NOT saying there is anything wrong with stock coils, but if MSD is so bad then why is everyform of racing use them. Also MSD doesn't change anything about what the coil can produce, its just a tool to get that little extra HP out of an engine.

With AEM does it actually have an MSD built in or why do you say "just go with it"

 

[andymoraitis]

I tried a little experiment today to see how much the MSD does for spark plug gap and the results were pretty much what I anticipated.

At 27 psi and a plug gap of .032 it misfired badly at WOT in second and third. The same misfires continued until I reduced plug gap to .028 in increments of .002. Whoopdee do for helping out on that score. I'll bypass it in the next day or two and I'd venture a guess that without it I'll probably need to reduce gap to .026. This doesn't bother me in the least since I didn't buy it and the dealer certainly didn't mark up the car at the time of purchase as a result. I treat it like an unnecessary free accessory that came with the car.

I'm confident that it would be better with a COP setup, but how much remains to be seen.

 

[Elvenhome21]

So far seems like decent results, keep experimenting and as long as the tests are remotely consistent for temp and fuel I would say it will be accurate enough to give a definative answer without resorting to a dyno. Also if you could publish the varibles and controls, ambient temp, fuel, type of run, plug gap, plug type and A/F ratio. Also if you could do a test between what ever plugs your running (hopefully NGK) and just some plain autolite or champion of same temp range. That would be cool to, just to see if the fancy firing tip actually does anything.

The one thing I enjoyed with MSD was the studder box launching capabilities. At the time I didn't have a chip.
