I purchased a used 2016 hellcat a couple weeks ago and when going to get new tires I found out the previous owner already had the wider wheels then going into all the different pages it read that im hitting 14-15lbs of boost. Is there any real way to find out if i have an aftermarket pulley and if proper tuning has been done to use the extra boost right if its really making that much? Thanks in advance.

Grab a caliper and measure the upper pulley and compare that to factory size. As for tuning, you could get with one of the forum vendors and talk with them about setting up a remote logging situation to see what's going on in the ecm. Until then, keep a CLOSE eye on your afr gauge to make sure she's not going lean, and definitely keep good fuel in her. And until I knew exactly what was what, I wouldn't beat on her too much. Better safe than sorry, until you know where you stand mod-wide and what's required as far as fuel and such.

Also, post up a few pics of the car. Maybe someone here has some info on it. Or maybe even one of the vendors worked with it. Never hurts to try........plus, we get to see another cat. And that's always a plus. 😁

At 14-15lbs you def have an upper pulley and maybe a lower one too. Id say you have at least the 101 goto mods. Did you buy her from a dealership? Doesnt sound like you interacted with the previous owner.

Yeah I got it from a dealership car was a 1 owner from New York im in indiana. Car runs 13.5 afr at wot. I've seen a few pulley kits that seem to resemble this one but it also looks stock to me at least. New to dodge scene since the others won't fit 3 car seats into a car I like. Thanks for the replies ill check into the other forums as well.

Nice! Is that the gomango? Looks great with the tint. What part of Indiana? I'm down in Evansville, just up against Kentucky.

I like the gomango. Pretty color. Google "Speedysgarage" and watch all his videos. He has a gomango "Go Man Go, he named it" 2018 (?) standard body. Super high quality videos showing how to do maintenance and upgrades and such. He spends a lot of time on "the other forum". Super bright guy, and a good way to get introduced to the hellcat platform.

Thanks. I'll have to get it on a dyno to have it gone through just to make sure everything inside is running like it should be.
