what does it take to drop a pulley, mechanically? Do I just go buy a 2.8 pulley and it bolts up? I know the tune will need adjustments.

 

you will need a tune,injectors, tensioner pulley depending on the size, cooling mods aswell

 

Yeah I know that, but how do you get the 3.34" pulley off? I'm a 2.4 s/c. Forgive my M62 ignorance, I never paid attention to the 2.0 threads until recently. Do you need a new hub to get the 2.8 to fit?

 

i'm going 2.9, i won't need a tensioner will i?.

 

yeah intense or zzp has them

stage 2 belt will be fine

 

im seeing 15 with the 3.06.

::shrugs::

boost is irrelivant anyways

 

i hope to see 17 soon on the 2.5

 

you won't

 

hm, sure about that....

 

yulp
::shrugs::

i got nothin

 

we will see after a few parts get changed out..

 

i see 17.5 on a 2.7 with ease.

then again, this is going off the maf calcs of 1.20/14.5

 

i saw 22.5 on stock exhuast before lol, then i went full 3" and dropped to 19.5. Im hoping the ported head and blower will lower that a little more, if it doesn't oh well

 

well, you have your dreams, and thats all that matters

 

I hit 18psi with a 2.9 int 30 degree weather lol

 

dreams for now, got to be a little warmer to start the work

 

Yeah, Im from Charleston SC, so pretty much sea-level here and on cold nights, i've seen 16.5-17psi on stage 2 only, but as everyone says, depends on a lot of variables.

 

I hit 100!!! Kpa that is. Damn Canadian Gauges.

 

100kpa = 0. or 14.5, or 1 bar. or one atmpshere

blah blah blah

 

sorry guys i'm a little car dumb, to swap from stage 2 to 2.9 i need to take the belt off.
where is the belt tensioner located?. i asume i would have to lossen it to pull the belt right?.

 

Sounds about right. My boost gauge needle hits the line right before 20. So, w/e that aounts to.

 

I see about 16.75-17 psi with my 2.80

 

bump

 

Yes you must take the belt off, the tensioner is right next to it looks like a little shock absorber with a pulley on it, a little notch next to it 15mm wrench push it back towards the firewall!

 

then when the wrench slips and you smash your hand into the valve cover a couple times. you will remember to do it slow, and put a rag ontop of the wrench to soak up the blood that is now oozing from your knuckles.
