if you get a 2.7 pulley what other upgrades besides a belt would you need for the pulley to fit and work well? any pulley boys products or can you just throw the 2.7 pulley on and a belt and be done?

 

larger injectors and tuning obviously.

 

I would get some cooling mods as well.

 

yeah i knew the tune and injectors. but no other pulleys need to be changed. just pop off the stock on and throw the 2.7 on, a belt, tune and injectors and its good to go?

 

even though im not a grease monkey...i think its pretty wise to get some good cooling mods with a pulley smaller than 2.8 IMO

 

I think hes asking if you need a new hub.....and i THINK yes, you will need a new hub if you have the stock hub on.

 

well im getting stage III which comes with a dual pass. but i want a 2.7 pulley instead of the 76mm pulley.

 

I think your going to need to machine the SC snout too. As far as I know, the BilletFlow pulley is the only one that fits over the stock snout.

 

nate makes a 2.7 for the S2 hub

 

I actually offer a 2.7 for the GM stage 2 hub that fits with no snout machining. Also, if you go with my complete modular pulley system a 2.6 will fit without snout machining!

i think he may be asking if he needs a belt tensioner to go with the stage 2 belt or a larger idler pulley? if he isnt thats my question

 

You need a hub, if you get a 2.7 pulley go with ante, hes awesome

Here is the list

Supercharger Pulley Hub (Stage 2 GM)

Supercharger Pulley 2.7 (Nates pulley, getthe 4 bolts to, use blue threadlock)

Bigger Injectors 60# Siemenz

Custom Tune (This is the biggest one!)

Belt Tentioner (R.A.W Sells one I think)

I suggest a intake and exhaust, whichever you prefer.

That should be it. Thats what you need to do it right.

Also the Stage 3 kit requires you to have the Stage 2 kit already installed. They do not sell just a Stage 3 kit, tis a upgrade kit from stage 2 to stage 3.

 

the 2.6 barely clears.

the 2.7 clears just fine

you better pray a lot, or shift before 6700

 

yeah thats pretty much what im asking

 

lol... or pray for the money for a good tune.

 

why should i shift before 6700. if its tuned it should be fine.

 

If you plan on going with a pulley system and you're currently stock I wouldn't suggest the GM style hub since it limits the size pulley you can run. If however you do want to use that style setup, I can make a GM style hub out of stainless steel which has a smaller diameter and will allow you to go down to 2.6 w/o snout machining.

what about for tensioning the belt..is stage 2 belt fine on 2.7 or does it need to be used with tensioner..thats what hes asking

 

I believe most people running a 2.7 are either using an oversized or adjustable tensioner to limit the belt slip with that small of a pulley.

Nate

 

2.7 and stage 2 belt is fine.....ran it on my car for a while, never noticed any belt slip

 

might need a pulley tensioner for that small...

 

what about 2.8 will that need anything special to work with my engine and pulley system. besides the obvious cooling and tuning

 

2.8, stage 2 belt. good to go.

with the 2.7 you can run without a bigger tensionor, but you risk glazing the belt in a matter of two months

 

i could use the 2.8 with stage II, full exhaust, intake and tune. and my engine will good

 

thats a loaded question.
