anyone try this yet? has it shown any gains....i read an article where theoretically it helps the power increase, becuase it burns more efficiently(but thats according to advanceautoparts.com......yes i get bored easily)


just wondering...i searched for it, couldnt find anything

 

Yes, it helps... but not much ( like 1 - 2 hp for our engines ) Still I wouldn't mind seeing dyno results for gap to intake versus gap to exhaust.

 

interesting.....wonder what that would do for a 350 then....

if i had the funds and a place to dyno it, then i happily would show the results...

and according to that article, the exhaust was the best power providing angle....but thats according to them....
Edit: what about fuel mileage??

 

watching, and the best results would be for the spark to face the Intake Valve.

 

i'll try it this weekend....and probably look for mainly any fuel improvement....so i want the back side of the electrode(that little metal stem, side connecting to the threads) to go towards the intake, or towards the exhaust?

 

Intake, from where the air is entering, so when the flame comes in travles towards the exhaust.

 

Did u do this?

 

Sorry, I need a bit of clarification. So by indexing, you simply mean the direction that the gap opening is facing? I can't imagine this doing anything whatsoever, but hey...just since I heard about it, I'll make sure mine are all facing forward next time they're changed...

 

Actually the gap should face toward the intake valve for a "better" burn, so the flame then travels toward the exhaust valve. Sounds silly, but no problem trying it, right?

 

no sorry, didnt get to try it....its been a rough weekend, and day, so hopefully, if i can get some indexing washers then i'll try it...

 

The gains are so minimal if any it is not worth doing. It is a pain in the ___, use a sharpie it helps a little.

 

forgot all bout the sharpie.

 

ya, sharpie, ruler, and those washers....anyone know anything about them??
