Here is the thread I found it on

You can actually get a 2.3 pulley to fit if you modify the snout. Crazy

Pretty cool chart






The Chart above is comparing boost levels of the TVS, not stock blower

Here are the stock blower estimations from the thread above

Here are the "approximate" boost levels for various M-122 combinations:

3.00" (OEM).............9 lbs
2.80"......................11 lbs
2.60"......................13 lbs
2.50"......................14 lbs
2.40"......................15 lbs (Mine)
2.60"/10% lower......15.5-16 lbs
2.20"......................16.5-17 lbs
2.60"/15% lower......16.5-17 lbs
2.20"/10% lower......20+/- lbs

Mmmmm...

Headers first...then we'll see about the 10%

wow

Belt slip waiting to happen.

Oh but what sweet music it will make

who will be the first to get it?

Ordered a 2.385" pulley for the VMP TVS from Sylvain. I am receiving one of the first 15 he is producing. Since the snout is already turned down this is the smallest you can install. Will see an increase of 1.5lbs of boost for 17.5lbs with catless exhaust. With stock exhaust one would see 18.5lbs. I really did not want to go with a lower OD pulley and this is only a .5lb lower than a 10% OD would produce. No belt slip from the few prototypes seen yet but there are easy ways to fix that if need be.

I dynoed 650rwhp the other day so this should add another 30rwhp plus I think Jon will find a bit more. I have had issues with Justin at VMP and his tunes. Ordered Lund tunes...live and learn. I am sure Jarrod would agree.

David had problems with his vmp tune as well. Hes now running an archangel tune and loves iy.

Very cool Chad! Keep us informed.

Excited to see the results Chad! Damn thats a small pulley! And yes I do agree :) Not a VMP tune fan, nor is David. Lunds tune has performed as expected, even a little rich at the top for safety. Would like to lean it out just a touch. Might get with Van at Revan Racing and see if I can squeeze an adjustment out of Lund at no charge :)
