Ignition/Distributor upgrade? Little help...
#32
ok boys and girls,let me clarify,i thought that likesfastboats was speaking for the op,i now see that is not the case but he somewhat hijacked the thread talking about his engines,that he failed to mention are supercharged so,will the op benefit from the addition of a msd ignition on his basically stock n/a engine,imo the answer is no,will likesfastboats supercharged engines benefit from the msd ignition,absolutely,as the boost goes up so does the difficulty to ignite the fuel in the cylinder,now the hotter spark can fire the plug and start the combustion cycle.if i did not believe the msd is necessary with the supercharged engine,i would not have them in my supercharged boats.i cant make it any more clear than that.now if anyone wants to tell me i am wrong,im all ears and always like to learn,so lets have the facts,just the facts please.

You are right. I know from expierience that all of the parts have to work together and compliment each other. That's where a lot of guys go wrong. Just upgrading one part ie: cam, carb, heads, etc. sometime will set you backwards instead of helping. But you really can't go wrong with a well timed hot spark.

When do spark plugs become an issue, what I mean is when making changes to the rest of the ignition system does a change in plugs become necessary? If so, how? Not trying to hijack as they are part of the system too. Randy

Ok I think we might be getting close to all being on the same page. I didn't mean to hijack the thread just want to tell of my reacent expierience with MSD's. "The thread's question was about ingition upgrades" And sorry I didn't mention my motors are blown, yes I agree that makes a big difference. I know the increases I saw are probably not typical or the norm. That's why I said I was "amazed" in my first post. Also I agree a NA motor will not see these gains from an MSD upgrade. Never the less I am a fan of MSD and do believe any engine would see some benefit from an upgraded ignition. Eaiser starts, smoother idle, better throttle responce and possibly a pony or two due to a more complete fuel burn. Sorry I got every one so rilled up. I didn't mean to turn the thread into one like the ever so popular SRW or Dually threads. The weekend is here so lets all go churn up some water and pollute the atmosphere a little more!!!

by the way what do you tow with drw or srw,lol,just kidding,its all good and just a misunderstanding,in the original post the op said he was short on cash because he just spent a lot of money on engine parts,i can totally relate and thats why i suggested that he stick with the thunderbolt 4 setup,why spend money on something you dont need,espically when money is tight.if he was running any type of power adder i would have suggested that he bite the bullet and upgrade his ignition,so at the end of the day,you and i might be on a different paragraph,but we are on the same page.

most of the aftermarket distributors have roller bearings instead of sleeve bearings. old guy that tought me always ran 8 guage wire from block ground to cylinder head(s), told me made 6volt ignition more reliable, simple/cheap so always did it. well several years back turbo mag for rice burners does dyno test, good for 5hp back to back testing. i normally go up in ignition primary wire size also.

The TB4 uses a module to control the timing advance curve. The V8-HP module has about the best curve for a performance engine. It has 20* of advance all in by 3000rpms.
