MSD Ignition

[BoxsterRS]

I really don't know much about this so this is why I'm asking!!! What does a MSD CD or digital, which ever model do to the engine? And how does it benefit it ? I've read the claims made by the manufacturer but want other opinions on the matter. Is this a worthy investment? What purpose does it have? Can it be used with my Boxster and would I need this (Tach Adapter (Cars with Magnetic Pickup Distributor))? Just want to get informed

MSD's claim to fame is "multi-spark" systems that increase the voltage output and fire the plugs 5-7 times within the time frame a normal system would fire the plug once. I've used their systems on race cars, where the extreme compression ratios and engine RPM ranges can (and do) benefit from this technology, but see no real advantage to them for street applications as the coil pack systems these cars have from the factory work just fine. You should also know that MSD systems operate at very high electrical frequencies, which reek interference havoc on car stereo systems........................

Good to know, almost everyone I asked after the post said the same thing, it messes up their electrical stuff. I don't plan on using the car for extreme racing but would like some street/track improvements. Thanks for the info!!!

The only thing you do get from the MSD if you get a DIS-6 is the two step revlimiter. You can engage it with the clutch switch or a button on your steering wheel. Lets you do full throttle launches but holds the rpm to 5500 (or whatever you set it at) with a secondary lower REV limiter that you manually engage.

I use it on my Turbo Talon and it lets me launch with 10psi of boost from a large turbo right outta the hole. The car is AWD and goes sideways through first. Push the gas to the floor hold the rev limiter button that holds the engine at 5500rpm. The full throttle spools up the turbo then when the light goes green let out the button and clutch and holy **** away she goes. Much better than droping the clutch, with part throttle holding it at 5000rpm or so ish.

Could be fun on a Boxster with RWD.
