Side gapping and Indexing

**blackSS01** · 03-18-2011, 10:26 PM

Old timers that know what I'm talking about, discuss. Does it help any little bit to do this to the plugs?

i dunno about side gapping, but i know indexing doesnt do much for modern engines

All my research points to this combination helping but not being worth a hassle. One of those "ever bit counts" thing

yeah, indexing allows for a consistent flame front each time it fires

I read that aiming the plug gap towards the intake valve doesn't really do the trick. The key is finding the sweet spot which is impossible to the average joe blow. You can get lucky I guess

This what I've gathered as well. Varies from motor to motor. The jeep guys are all into it, making a bigger difference at higher rpms. All in all, not worth the hassle.

I'm def going to do this on my toys (They are no hassle) and see what the SOTP feel is.

I'm doing it on a scooter and a snowmobile

SR20 guys are swearing by this (MPG) One guy actually dyno'ed before and after 3 times average and he said he picked up 7rwhp

That is within the error of the dyno but at leasts he tried.

If it helps with 1 mpg on my toys its worth it since changing plugs on my toys are too easy.
