Just wondering if anyone is running a 2.4 or 2.3 pully on the m62, I saw both sizes for sale somewhere and cannot remember where it was? Also, supporting mods to run such a size, and if it is safe with mods and a proper tune?

 

i dont think there is enough cooling for that lol

 

If you want redline at 5k lol!

 

sure if you want to blow ur **** up, boost isnt everything

 

wouldnt be beneficial because of the outrageous amount of heat you'll be making.

 

I've heard of 2.5 pullies....

 

lol^^

 

Do they come with a new motor?

 

well i have some cooling mods in store, running meth dual pass and 2 heat exchangers now, but i have a plan to redo the entire cooling system, so should i just get a 2.5 then? and if it blows up it blows up, at this point its time for a rebuild anyway

 

2.5 is not the max, but in reality, 2.5 is the max. lolz

 

lol about 5 minutes after installing the 2.5..................BBBBBBOOOOOOOOOOOMMMMMM!!!!!! !!

 

I am at 2.8 and i dont think i will go any smaller....I once thought going to the smaller pulley was the BEST for a SC car..Indeed its not even close...all about keepin its cool lol

The Best time on the stock M62 with 12.75 is on a 2.85 pulley BTW

 

blower efficiency drops off hard below about 2.7




I think.......




2.4 is probably going to do damage to the blower itself by overspinning

 

if you have the money for a rebuild, **** the 2.5, just get a turbo and make more power for less money.

 

in for lulz.

 

I remember my friends and I were doing the calculations for if you cut grooves into the blower shaft, and just ran the belt on the shaft with no pulley

I forget, but it was something like 125,000 rpm on the blower at 6500 rpm for the engine

 

lol how much boost would that be then tho?

 

It wouldn't be making boost at that point...it'd be creating a black hole and sucking everything into it's empty vortex lol

 

hahahahahahahaha^^

 

according to the calculator i found, that should be 163psi

 

That's enough to push the cobalt down the track in about 1.3 seconds...or 18 hours 53 mins on simply 163 psi pushing the car lol

I still say it'd be creating a black hole in which you, your car, and all surrounding neighborhoods would get sucked into for eternity lol

 

Well, at that RPM, the rotors would have exploded out of the housing, through the hood, and probably 50 feet from the car. However, provided it held together and managed to keep building pressure without bleed back, I'd say 160-180 psi? For about 10 seconds, until the intake manifold melted

 

 

It still would be cool to see
