well the ngk v series is what i compared to in every test,,,,, so if you had a back to back test, between v and std, say it,, just dont say im wrong,,, tell what you found... lets be productive here and all try to learn off what each other has found i have no clue if they make an "ar" series in a 3/8 reach every pro stock guy i know runs autolite plugs,,, but they prob get them for free,, cause i do..

Plug gap is dependant on cylinder pressure/voltage , those cut-back plugs are/were 'marketed' for high HP motors running high cylinder pressures , hence the tighter gap.............some guys on here running NGKs will be pulling em out & cutting the straps back , will also go through two sets of cut-backs to one set of standard type plugs...........maybe the cut-backs worked better in you're application due to problems elsewhere , might not gain in every application , the NGK 'V' series plug definatly did'nt help regards my combo.
With respect.
I never seen the V or 4 point grounds do anything for power but did get a lot longer life out of them... I had a set given to me for my street rod(I would have never bought a set)... same principle ... electricity goes to the easiest ground path

Plug INITIATES the burn , that's all it does , too cold a plug for the application 'may' leave a 'tad' power on the table due to unburnt fuel residing in base of plug , then you have too hot a plug 'may' leave a 'tad' power on the table due to mixure being lit off 'slightly' earlier , pretty 'negligible' which ever way you look at it.
i think you can make out anything you want, and put what ever numbers that are in line with that, to be the truth. still when you talk of ngk race vs ar race plug and all you do is change the plug , you cannot , will not gain 10 hp peroid !! the only way it could add any hp is if that cyl (s) wasnt fireing , or plug(s)fouled!! if this was any kind of a true senario, ngk, motorcraft, denso, bosch, ac delco, pulsar, and any other plug co, would be out of buisness tommorrow over such a find , it would be historic perportion in the racing world OOOO MY GOD ,, my prayes have been answered ,!! all i need to do is buy set of $ 15.00 plugs please keep this going i can see people throwing out there plugs now

I did say it , no power gain using NGK BCRES over the 'V' series NGK , just talking out loud which had nothing to do with autolites.
I personally don't use the autolite plug due to it being harder to read (nitrous) , i prefer the NGK being the fuse as opposed the piston with the autolites.............maybe you got lucky the way the autilite was indexed as opposed to NGK.

What plug number would it take for a steel headed bb mopar, with a 3/8" reach, and a 13/16 wrench size, I have ran NGK'S for several seasons, and would like to do some testing with the autolites, and see if there is anything there?????????????
Thanks Dave
Try AR74, AR73 and AR72

well this all started with a customer telling me they picked up 7hp on koffels dyno,, dean nicopolis,,, so i told my friends in louisana,, caro and teuton,, they gained,, i told westcott,, he started running them all the time but never tells anyone anything,, but him switching over said something,, then i got a dyno,, i did it,, gain,,, so we all gained.. nothing to do with indexing...
they are harder to read than an ngk plug,, and ive had a few buddies that run nitrous and said they didnt like the autolite for some reason and went back to ngk
i ran ngk heat range 8, 9 and 10,,, compared to ar 51, and ar 52 plugs and the autolite were obviously better,,, though tried a gap change on the 9 ngk plugs and on the 51 ar plugs,, and end up with an ar51 gapped at .025
i would wonder why all the pro stock guys run them then,,,, to be honest i didnt believe it at first either.. my friend james told warren barnett,,, he said no way,, then did it and gained around 7,, and had to try to find out why cause like you two guys,, said no way could it gain,,, i on the other hand dont care why it gained,,, it just did,, i did think about it a lil,,, but moved on to bigger things,, like working on controling the valvetrain,, or ring seal

in a hemi we never usually index the plug,, just put them in,,, and its always the same hp,, with the same type of plugs,, if indexing would matter it would make power change some up or down cause the "new" plugs wouldnt be indexed unless you got lucky
in bb chevy motors i do,,, i have to index the plugs,, or fords,,, or else the piston would hit it
the biggest gain i ever seen in indexing plugs was about 200 or so, made a high 600 number, piston hit just enough to close the gap off,, so just swapped the 8 plugs around in the motor till they tightened in the right spot,, i looked at the numbers as the dyno guy was laughing, along with his dad,, after the 1rst pull,,,, he didnt see what i did,, then i walked back in and said pull it again, 950hp, he asked me about 10 times.... what did you do??? the dyno operator was charlie westcott,,,, he has a dyno in his barn,, this was 6 or so years ago

Really...over 7-10HP? So the fact that I just gained 17avg HP on an engine I freshened for a friend of mine should rock the racing comminity?

Maybe it's time for some of us to keep our secrets secret Your results may vary I remember the same comments on switching from a stock street Hemi dual point distributor to a converted Hayes S4 ignition in the same distributor from one race to the next, the car pickup almost two tenths and right at 3 MPH with that change only Several well known "stock" class racers said no way, but they did have the Hayes ignition on thier cars at the next race

I had a mid 10 sec stock headed 340 pick up almost 2 mph when changing from standard NGK s to V power NGK s... so there is something in this, maybe it s time for some testing

yep just buy some autolite plugs that will do it lmao
ooo and please ,, if you do have any more secrets like autolite plugs , keep that one , to youre self, that way noone will know why youre car picked up that 2-3 mph and that 1-2 tenths, and you can charge a guy a bunch of money when you work on his car and make it go faster . wonder if it makes a diffrence if i was to use motorcraft plugs?? but they said only autolites mmm

mr p i'm sorry i great respect for you ,, but this is just plain outright b s , as i have posted before, you cannot gain up to 10 hp over any plug by autolites, plugs,, not unless that plug not firing, or is in the wrong heat rang indexes is not what it all is either, yes min gain and the work to do it , yes some motors you have to index, sometimes yes 7-10 hp doesnt take alot for a motor to pick that up, air quality, wind, when its on a dyno, and that statement comes out i will go back and say, that the plugs are bad, just as a set of wires can have to much resitance and have the same effect, other than delivering the ign to fire that cyl, thats what the plug will do my testing has come from the track,i have used 100s of plugs ,at the track & on my own, i have used autolites, motorgraft, ngk champion, bosch, ac delco, i have yet to see any plug, pick up over the other ! i have run gas and now alcohol, i have change plugs at will, on both yet to see even so much as a hundreth of a pick up, if a guy has a gas fouled , oil fouled ,etc plugs yes he will see a pickup yes even on a dyno,
