FB definitions change by who did what and where, as much as how much of a variation there is to being stock. Again changes by who and where.
100% Stock is as delivered in my books.
The term stock has since included a tire or a wheel and tire, and stretched all the way to leaving only the driver seat in.🤷♂
I always mention stock power and then mention what I did to stray from stock. Yet I still get called out on FB so I haven't bothered posting the runs from the day we met or the weekend after. It isn't worth the time and discussions that ensue.
The one over there that has the biggest issue with my times as not stock (even though I only said stock power)
has a CAI and judging by the sound in videos, has exhaust mods also.
They also posted the stock record for a RE that had one seat. Yet I got blasted for weight reduction. Which was exactly like when we met, air compressor still in and and all.
So stock depends on lots more than simply stock. Oh and I got told 100% stock HC is with a 17" drag radial. LMAO
But then didn't accept my times in that set up.
I have no problem with variants of stock, just be honest about it and don't change definitions daily.
I always use 100% stock to be as delivered so that others can argue the rest.
I doubt you will get every one to agree on one definition especially on FB.
