I feel like I need more tension since going with the 2.8 pulley, after searching supporting vendors I found two options,

this is a larger than stock tensioner pulley... price, $18.00

and

this is the adjustable tensioner from zzp, price $109.99

keeping the prices in mind do you think the larger tensioner pulley will do just as good as the adjustable tensioner?

 

are you running a stage two belt?

 

Just run a stage 2 belt, that will be fine with the 2.8.

 

yeah I am running a stage 2 belt but it squeaks!!

 

What squeaks? Just the belt?

What brand pulley are you running? I ran a 2.8" for two years on a stage 2 belt with nmot problems.

 

make sure the belt isn't loose / off track. Try using some belt dressing and see if it stops if not. Or... make sure it isn't something else squeaking.

 

did we forget about the crank pulley? adds more tension, boost, and more surface area grip for less slip

 

hmmm didn't come across that..

 

i have a 2.8 with the stock pulley. I did my 2.8 before the smaller belt came out and i just went to carquest and matched up a little bigger tensioner pulley

 

there is only like 3-4 vendors selling it. had about 3 group buys them in the last month from OTTP, MRZ and GMA.

 

What are the cons of it tho because I remember some people did not recommend it...??

 

well bbitz06 did the ott stage 1 upgrade...and his pulley came off while driving and shredded the belt

 

they didnt recommend it cause of the bolt. it was only supposed to be used once. but they are now selling the bolt with the pulley, it was torque to yield

 

That's no good...Has that happened on more than one occasion or what?

 

nah it was the first time...only problem his car has had

 

yea and it's some bullshit haha should be fixed sooon honestly i think one of the bolts back out and made it track wrong and then ummm come off.....even though a checked them 2 days before it happend.... moral of the story use loctite!!!!!!

 

The oversized tensioner pulley requires you to remove some material from the tensioner unit itself so it does not rub. Imo if you are fine with that its the best option becuase of price. I ran the oversized tensioner and stock belt on a 2.5" setup for 3 years with no issue.

If you don't like to modify the tensioner pulley there is always a new stage 2 belt you could use.
