    If you have a car with a power steering pump.. you can actually just use the stock 2020 scat pack belt size and itll fit perfect 👌.. non ps needs the 1" shorter.. any competent auto parts store can find that for you.

      Hey I got a few bolt ons should I go with a 18% underdrive? Or 15% and do I need any belts I got a 2020 scat

      Would this apply to the 2015 5.7 belt as well. I'm using the 15% UD pulley.

    Nice! I've done pulleys in all my Rams and one day will do it on my 1320, but not till after I see what it does with weight reduction only. I had similar results in my Rams too. I dyno'd one once and I think I gained about 14 hp with the underdrive pulleys.

      @@Fawazalsobay when I talk about all my Rams, they were actually all pre-hemi. A 93, 97 and an 02. All with the 318 and 360 Magnum V8s. The 93 and 97 I had March pulleys. Not even sure they're around anymore. My 02 I think it might have been an ATI though. I honestly don't remember. I'm definitely going with this same ATI for my 6.4, and if I were getting one for my current 5.7 Ram, I'd probably go with ATI also just from what I've read about them.

    I got a question about running my car on the dyno, 2010 6 speed R/T. I went to a dyno day at a local stang shop just for fun and my numbers were WAY low for my setup. 1st pull 420whp, 2nd pull 450whp. 392 cam, 7psi, long tubes on 93. I held the TC button until the ESP BAS light turned on. However traction was still kicking in, and is why my numbers were low by 50+whp Any way around this?
    I was on a Dynojet, a stock 5.7 made 346whp right before me.

    • @OMGITSMRMACK

      It doesn't change anything in the tune.. i plan to tune the car.. but the pulley literally will not effect it at all.. and anyone who tells you differently is a tard or just out to rob you.. its a legit bolt on with nothing else needed.. I guess thats part of the beauty.
