Hey guys, I was just wondering since EvoSport isn't the most dependable vendor and they are possibly out of business, is there another company that sells underdrive pulleys for the N/A engine?

 

Is there an underdrive pully upgrade? or are you just talking replacement parts.

 

EvoSport used to make underdrive pulleys which freed up to 13hp to the wheels in 1st gear, or so they claimed. I know there's other companies like ASP and BBK but I don't think they make any for the M112 engine.

 

UNDERDRIVE? I am not understanding the concept.

What pulleys would you replace?

 

Mark, under drive pulleys spin the alternator, AC compressor, power steering pump, and water pump slower, thus supposedly freeing up some more HP.
( smaller crank pulley, larger alternator and PS pump pulleys, same belt )
I don't believe anyone has ever posted any dyno runs confirming this, and exactly how may HP you get for the $$$$$.
I messaged with latemodel21 back early this year about making a few sets,
I will defer to his expertise as he advised me to not waste my money.

 

If we are maxxed out on the 3.2 and have no where to go...... $400 isn't bad for 10+ whp.

I'd love to know where I can pick one up.

 

this place 'says' they have them, give them a call :

( remember, you have the M112 non-supercharged engine, same as a 2003 SLK32 )

EDIT : Never mind, I called them. They USED to get them from EvoSport, but since that entity no longer exists they have been unable to find a new supplier.

 

Fooey...

I was afraid of that
