What is the smallest pulley you can use without a bigger tensioner and just a shorter belt?

 

you can use the search button it will tell you

 

2.7"

 

Have you tried it yourself? I just dont wanna have the belt shread on the first pull lol

 

i ran 2.6 on gms2 belt

 

Okay. i already have a heat exchange that was installed before i bought it and i dont know if its dual pass or not. Does it matter if i run a 2.7 or 2.6 without dual pass?

 

no it does not... i never had dual pass... IMO not needed at all (not that big of a gain)

 

Okay thanks

 

2.7 is fine, im running that on stage 2 belt on tvs

 

I have a 2.6 and IMO you can probably fit a 2.5, but why would you want to?

 

Not trying to thread jack, but running a 2.6 did you machine your snout?

 

you need to machine you snout for a 2.6 and i wouldnt run a 2.7 without meth

 

yes.

 

Not true. Use a ZZP pulley/hub and you can fit a 2.6 w/o machining. Also, the 2.6 is the smallest to go w/o belt slip. 2.5 is best to have a larger tensioner

 

but I had smootheflow, even though smootheflow said a 2.6 would fit without rubbing, it didn't..

I don't think you would need a larger tensioner for a 2.5, pretty sure there is really not that big of a difference between the 2, but who want's to overspin their blower?

 

it says on zzps site they run down to a 2.7 without machining
so i thought it would need to be machined for a 2.6

 

My 2.6 and many others have not required machining on a ZZP 2.6

 

Okay so im gonna get a 2.6 with a shorter belt and 60# injectors and harness and a tune. I have a heat exchanger already. Do i really need a dual pass?

 

with a 2.6 you are going to generate a **** load of heat, you dont have to but be prepared for high IAT after 1 pull- install meth you can get away without cooling mods. The cooler the better. With an extra HE it will help and you have that.

 

DAMN SON! aren't you going to check the water temperature before you jump in!?

 

if you want to run a 2.6 get meth and a dual pass

 

im going to a 2.6 but also with a 3 in intake and exhaust, dual pass, griffin h/e, 80's, p&p head and e85 you think i will be alright?

 

You guys are able to run a 2.6" with just a shorter belt and get no belt slip?

 

I didn't have slip

 

Good to know. I was going to get an oversized tensioner when i bolted up my 2.6 but if i don't need it then thats even better
