Got mine today. Hopefully I can install this weekend.

I'm curious on how these work on our trucks someone post a review when u get it installed

 

[greychevy]

Anybody had a chance to install yet?

 

[smokinstorm]

Having one helluva time finding someone with a puller to remove the stock damper. It looks like I'm going to have to bite the bullet and buy one myself. This is quite the bummer that no one at any shop around here has the correct puller. Wow. One of the perils of living in Hodumpville, I guess. Is anyone running into the same problem I am???

 

[Lhemi]

Same thing here, if someone would please post how to, how hard, butt Dyno, real Dyno. Was it worth the $350???
Results please!!!!
That's why I never pulled the trigger. I couldn't really see the Benifit in it. What mods does it support? What all do you have to change? Belt size? Pully size?
Thanks for the info!!!

 

[TylerB]

So far it seems no one has installed theirs, so no results yet.

I'm still waiting on the dealership to get my new crank bolt in stock and then I can turn the washer down to fit in the new pulley hub. Need to do some calculating and figuring for the new belt size.

hopefully it doesnt drop power steering or the alternator too low, thats why i havnt gotten one. I AM AFRAID

Plenty of 3rd Gens. running a 20% UD without problems, this one is only 15% and we have a higher output alternator.

Nothing to worry about.

These must be some pretty sweet desk trophies.

Someone hurry up and install one!

 

[fasthemiram12]

Unfortunately mine won't go on till the motor is built...

 

[Lhemi]

So did this ever happen? What where the results possitive and negative?

 

[emjohn4]

It did.

Apparently there are 10 sweet desk trophies...

So, the positive is that they are all still pristine.

Nah, mine is in the closet holding down some other part boxes.

Same here....doing everything at once when I get time. Not real motivated with all this hot weather.

Mine is still in the box but it is in the truck tucked in nicely behind the driver's seat. I just hope it goes on without having to re-invent the wheel. What's the deal with this having to get a new bolt and make a new washer from scratch in order to install it I read about? I work at Ace and have several thousand fasteners to choose from so if I need something special, I might have it right there in stock. Oh yeah, it's pretty much a no-go on getting a larger water pump pulley to underdrive the water pump a tad more. No room to make one appreciably larger. Alternator pulley is a possibility but since the alternator makes drag based on load not speed, no real gain there either.
