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?

an0malous

larger injectors and tuning obviously.

I would get some cooling mods as well.

srcobaltss

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?

J.CobaltLT

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.

srcobaltss

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

Nyke

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

srcobaltss

yeah thats pretty much what im asking

UmeNNis

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

srcobaltss

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

nherbst454

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

nherbst454

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

XCRuna1201

might need a pulley tensioner for that small...

srcobaltss

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

Area47

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

srcobaltss

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

Area47

thats a loaded question.
