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

@brianschargerrt9416 Жыл бұрын

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.

Great I have 5.7 ram 2020. I'm looking for the best pulleys in the market. What do you recommend? Ati or bbk

@Scavenger1320 3 жыл бұрын

@@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.

ATI dampener comes stock on 392 crate engines, not the underdrive pulley, but you can easily swap to an underdrive shell if you so choose.

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.

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.
