I have a guy saying I'll pickup 3 tenths with v power ngk he's kind've a nut.

 

[ch1ll]

Your champions weight 300 lbs more than the ngk’s?

Exactly! He keeps harassing everyone saying he built Hemi 9 second car etc for 35yrs lol! I'm like ok dude whatever.

He doesn't have one car that's still together.

Ngk v power vs. Champion rc12yc.

If your asking from a performance standpoint then I would say NGK, reasoning being they are easy to read for one and I think for the most part is the preferred plug for most engine builders when they put them on the dyno. These guys aren't exclusive to one particular brand or another most of the times, they use what works best and what has been proven to make the most power.

NGK

But will I gain a 3 tenths to second using them? Lol that's the claim by a certain guy I know.

Point is if he thinks that just changing plugs did all that and brand something else is way off.

No and I wouldn't make that claim either under normal circumstances

Whatever's cheapest.

I like the way you think! Lol

They're all about the same, regardless of what some will try to tell you. The only exceptions are the snake oil stuff like Splitfire, E3 and "those" kind of "plugs".

And my way over carbed and cammed, ported oversized valve Harley. They Work the BEST, for Me

So your basing your response off of what? Your 125 hp Valiant? How many high power engine builds you been around and with the builder and got direct input from them during the dyno sessions...plus you don't think racers themselves will not try different plugs along with a few dozen other things on a car to see what gives them the most performance? Come on now.....

Wanna tell me there is no power to be found in oil pan construction or even oil viscosity too....all the same?

Wow dude, Really?

 

['68cuda416]

To the OP....ever wonder why I don't post questions about why my cars don't perform at expectations? 3 reasons....My cars do perform at expectation, I have badasses that ACTUALLY KNOW **** helping me with guidance and education and also building what I need built and number 2 is example right here in this post.....you rarely get responses that will make somebody's car perform better outside of Ratbastid....he is actually very smart and should be listened to pretty much word for word.

 

['68cuda416]

Wow dude, Really?

Yeah really....when are people on this forum gonna stand up to truth and if it hurts someone's feelings then so be it. That answer of whatever is cheapest is 100% wrong AND the OP initial question and reasoning was to find out if one plug makes more power or not. I don't honestly think there are huge gains to be made but the fact of the matter is the fastest guys take ALL of those menial gains and then they add up to a winning car that nobody can touch.

 

['68cuda416]

Well, you sound like an Arrogant *** to me Dude. There are ALOT of People here that HAVE real World Experience, without relying on hired "Badasses".
How'd that work in high school for ya?

You learn from Badasses and wisdom tells you to steer clear of the dumb ones.......I won't elaborate any further

There is absolutely a difference. Just did this experiment 2 weekends ago.

Same cylinder. Same jets. Same air. Same fuel. Same RPM launch. Same oil temp.

The only difference was the plugs. The one on the left were regular Autolite 3923. The right one was an AR3923. Same series. Huge difference in A/F. The AR3923 was a big improvement.
