ATI Super Damper 15% Underive Pulley

Jwithing said:

Picked up a puller from O'Reilly's and have begun. I pulled out my fan for clearance and also picked up a 3.7 fan to maybe do the efan conversion. I have a 2015 and know I shouldn't need to swap, but I've been plagued with cooling problems, which I think may be fixed from my recent coolant flush. It's only 60's so hard to tell. My temps will get to 199 but then drop pretty quick to low 90's/ high 80's once my fan kicks in. Either way, thought I'd pickup the 3.7 fan for $85. I thought I'd post a pic of the 3.7 vs 2013+ fan for reference. My stock fan (left) is almost 20 inches in diameter while the 3.7 fan is almost 22 inches in diameter and has slightly larger blades.View attachment 126067

I am running two JL10W6v3's, so we will see. I've seen comments from other members with aftermarket systems say they had no issue. I figure worst case, put a capacitor in.

Little bit of an update... I was able to easily remove the crank bolt using a long screwdriver wedged in a hole of the pulley against the block to prevent the pulley from spinning and a 1/2 ratchet with some muscle. The removal of the pulley itself was a bit tricky with the puller kit I had, but was able to get it based on the link to the YouTube video below. Removing the fan was a must since I had to sit inbetween the engine and radiator to finesse washers and nuts on the back of the pulley bolts. I had to scrounge through my parts bucket for awhile but luckily had the nuts and washers needed. I think I'm in a holding pattern now until the gals get home so I can run back up to O'Reilly's and get the install kit.me and Didn't realize it was separate.

I was able to get a few threads of the oem bolt on, so I just used that. Having trouble now torquing down to 130 ft lbs because the crank is turning at about 70 lbs. Any thoughts on how to lock the crank?

Old school trick is to pull a spark plug out and feed some nylon rope into the hole,the rope will jam between the piston and head and keep the crank from turning

Sounds sketchy, but I guess I'll give it a try lol. Thanks!

It works good,lol. Pull both plugs on the cylinder you feed the rope into,so you don't risk closing up the plug gap on one plug. 1/4" nylon rope is what I use.

First impressions... The engine was definitely quiter, which has been observed by others. I didn't really 'feel' any performance gains, nor was I really expecting to. I did notice that acceleration feels much smoother. There used to be a tiny vibration that I felt in the accelerator that I always attributed to the exhaust, but it's now gone. Very subtle and could only tell with flip flops or bare foot. Or maybe in crazy, who knows.

I was sitting at a light and cranked the subs all the way up. I noticed no dimming of the lights and run 55w HID's and have led fogs. After 20 seconds, the evic flashed "battery saver mode" .... That's certainly new lol. I did not notice any difference but was about a minute from home. All in all, I'm happy. I didn't expect much and know it helps. Install was smooth for me at least and I was willing to shell out the coin for the mod. Didn't get a chance to check a 0-60 with the tuner. Still haven't gotten to at all since I've put my LT headers on as well. I'll keep you all posted if any further opinions develop.

Also, I ended up throwing in the 3.7 fan since it helps open up the engine bay and is slightly larger. It cooled the same, but I'm expecting it to shine better in high ambient temps. Only time will tell.

Awesome man good deal. Hope to get mine on in the next week or so. I'm just running the stock Alpine system so I should be fine. No crazy lights but I am installing a 35w HID kit tomm.

Yeah, the efan frees up soooooo much room up there. It looks a lot better and you can sit up between the radiator and block...lol
