Nice pulley kit. I'm currently having the same issue with the belt walking off. I do hpde and I'm supercharged so it's almost the same scenario. Initially, I thought it was because I spun out on track last time, and that caused the misalignment. So I swapped out the belt and it happened again this past track day. Glad I brought an extra belt to the track.Gonna check and change out the pulley's. Hopefully, this fixes it.
I tried to buy these like.. 2 or 3 years ago, after a few weeks of waiting, I canceled because they never shipped them. Excited to see how they work for you
I think my idler pulley bearings were going out which led to enough wobble to throw the belt in the right situation pinging off high rpm’s, haven’t had any belt issues since! 👍
Nope! Don’t quote me but even if you did the lightweight pulleys which does change how the engine spins in a sense, you still don’t need to retune. But these being idler pulleys only it doesn’t change anything in how it runs overall, the lightweight crank/AC/alternator pulleys are what changes the engines effort in spinning the accessory drives.
Cars are happy somewhere between being babied and being absolutely beaten on imo, they do want to rev, act like engines, get to temp, it’s unnatural for them to not go through their “full range of motion” if that makes sense, hence why babied barely driven supercars break frequently, but on the same token can’t be doing it all the in any situation. I’d look at it as working out but for your car in a sense, you have to stretch before you work out (or should), someone who stretches and works out frequently will perform better generally than one that doesn’t, parts deteriorate instead of staying lubed and healthy if left unused right? Same for cars as humans, we’re both somewhat machines. 👍

I haven’t had the same issue since! But yea I keep a spare belt around now too just in case 😭😂
I saw your car in a parking garage it’s so amazing I love it great job

I wonder if it was Covid related? They changed all their shipping to usps 2-day
Was this a fluke? I haven't had a belt issue in my turbocharged 86 that also sees drift days. I would like to avoid any hiccups in the future though.

@@ryevdee6064 good to hear. I should inspect mine to see how they are holding up. Car is 11 years old almost.
this helped a lot bro ty
Do you need a tune when you install this pulleys ?

update? Just bought them.
They’re holding strong! Haven’t thrown a belt since changing out those pulleys 🫡
I have a 2013 Scion frs and I never let my rpm’s pass 4 is that good or bad I’m too scared to go any higher
as long as you're not redlining the car every pull, you should be fine.
