den

whats msd ?

apreludem

msd ignition i think is what he means.

aurosting

yeah msd ignition do you think it really helps

truespin88

While we're on the subject...

Do you guys know if HKS helps?
Heh! I'm just messing.

MSD makes a lot of styles of ignition, what kind of ignition are you referring to?

apreludem

i believe it helps as far as giving you a better spark and burning the fuel more efficiently improving your gas mileage....correct me if im wrong please.

truespin88

That is true. Depending on which model you go with. I'm sure there are systems that aren't as potent as the stock one...

Nice writeup Ted.

jester1341

so whats the opinion of those with both installed?? is the MSD any smoother or gas efficent than the Crane cams?? problly a stupid question but if i wanted to get the MSD digital version.....at over200, would i need to buy two of them??[leading and trailing]

i was thinking about a multi spark system, but is it really worth it? i mean 1-2mpg and a smoother idle is enough for me to shell out 200, but is it gonna happen on my car?

lastly how hard is this to do in my own garage, in and out or out for a week?

All CDI systems pretty much do the same thing. A $300+ Jacobs box is going to to do the same as a $150 MSD 6A box. They all install on the leading coils, with the exception of the HKS Twin Power unit. Install them on the leadings first, as this gives you the most gain. You'll need two of them or a two-channel unit to do the trailings - this gets expensive.

Install page has been redone to include instructions for the Crane Cams HI-6.

is there any risk in running an MSD system on only the leading coils? and by expensive what are we talking if i wanted both[which i do......depending on cost of course]
and im talking about the MSD[digital or analog i dunno yet] since thats most likely what i would get.

u dont need to do the trailing right? just for better overall and if u have the money right?

MSD ignition has Analog circuitry and the Crane Cams has digital Circuitry. They both do Multiple sparks below 3000 rpm to get the maximum burn and then its just a high intensity single spark beyond that. I personally like the Digital Circuitry instead of the MSD Analog cause the analog just seems kinda cheesy.

Crane Cam is priced lower. I got mine for 148.88 with shipping from summit racing. MSD is priced higher and Jacobs is just out of the question.

They do improve gas milage by about 2-5mpg maybe more depending how your engine is. Idle is sometimes smoother and higher RPM power will most likly be improved slightly

I my self am putting in Crane Cams HI-6S ignition since it was priced well and has a rev limiter plus its all digital circuitry. and its a little small in design and not big and bulky like MSD.

Keep in mind that the Crane Cams "HI-6S" is not a CDI box.  It's just a voltage enhancer to the coil, so you do not gain the advantages of a CDI box.

so from what i've gathered its better to buy the crane cam digital CDI model rather than the digital MSD CDI model??

still wondering though, how hard is this to install??

RETed

It used to be that the Crane Cam HI-6 and the MSD 6A was similar; it's easy to recommend the HI-6 over the 6A.  Now, you can't find the HI-6 for less than around $200, which makes the 6A a more attractive option.

Install instructions are up on my website through the above links posted.

I used the msd 6a. Didnt notice any difference really other than a nicer idle. I had it while running boost. if you have an na then I guess you dont have to spend more for something that will basically just improve the idle(gives more spark at idle or around that range). Other than that dont expext much improvement.

I dont know where you got that from. I JUST bought the crane cams HI-6 ignition for 148.88 from summit racing

Justin

Crane Cam Hi-6 is a CDI. (CDI - Capacitive Discharge ignition) ever heard of a CDI Box? thats what they are talkin about. Crane Cam, MSD, Jacobs, and all those other items. Yor not loosing anything.

Justin

And if your wondering how hard it is to install go to this site below

http://www.fc3s.org/how_tos/electrical/hi_6.html

that tell syou step by step how to install it.

And the MSD is Anallog not digital. if it was digital you wouldnt need those annoying "pills"

Nice!  Last time I checked, it was $189.99 for the Crane Cams HI-6 and LX-92 coil "package.


-Ted

ViperDude152

ooo, well maybe with the LX-90 coil package.. lol. I didnt get the package i ust got the CCHi-6 ignition box. our coils are good enough for street / strip. for full blown out racing you may want to go with sumtin else.

My opinion is to not waste your time. If you find that a CDI box improves your mileage significantly, then you have other problems with your car and should probably fix them instead of band-aiding with aftermarket parts. Until you have modded your car to the point where the spark is actually being blown out by boost/nitrous, then there are other things that you can spend your $200 on (such as a tuneup).

ViperDude152

well if you want to root around in the engine to find out what EXACTLY is the problem for bad MPG then go ahead. but to install sumtin that would help idle and get a little better MPG then i woudl rather go that direction.
