Popped this beauty on today! You know we have a press-on made from this new material, but look at this! For those of you with our Quick Change hub, you've got a new toy ready to go! Swap over in minutes and pick up 1-2 psi, which means 10-20 rwhp and of course more torque.

I went from 20 psi to 21.79, picked up 20 rwhp and 25 pound feet of torque. Your results may vary, depending on your level of mods.

A fresh belt, an oil and filter change, snugging up the front end, re-setting and locking down the pinion angle, and a couple of pulls for an A/B. Busy day and hotter than hammered hell. Oh...temp on the dyno says 96.66F, humidity was only 24% but the DA was almost 3000ft (650 actual). Not the best day to do a dyno pull....and certainly not one where'd I take Christine to the track! But, a good day for the VMP Tuning R&D Dog!

Got a VMP TVS?? Grab one of these bad boys. We also have them available for the '13!

Same here...no slip on my 12 Shelby with 90mm idler and VMP 2.4 upper. I also have a slightly smaller belt than stock that I purchased from VMP as well.

Just an FYI. On my 12 Shelby with VMP 2.4 and stock lower, through the stock exhaust, the TVS made 16.9lbs of boost with the VMP 93 tune. Perfect for my street car!

What numbers did it put down? Dynojet or mustang-dyno?

Mustang Dyno. I need to get to a dyno jet to get that number for the masses. I truly love my car and can see not needing more power anytime soon.

Pull 2050rpm-6231rpm
AF-11.5-12.2
TIMING 18 degrees till 5500rpms, then 16 degrees till 6231
BOOST 16.9
WHP 621.2
LB-FT 607.6

I have the VMP TVS with the 2.5 interchangable hub. If I purchase the 2.4, will I need to get a retune? Thanks!

If I got a tvs with the 2.4 pulley would I over spin it if I added a 10 or 15% od?

On the edge. I run a 2.40 and a 10 % for 21-22psi @ 700 ft msl

I drive it on the street but never, ever romp on it.

With the correct timing/tune you can make that much boost and have a ton of potential with pure race fuel and a more aggressive tune.

Fueling mods are an absolute necessity.

Call me if you'd like to discuss.

PLEASE REACH ME VIA EMAIL AT [email protected] AS OPPOSED TO PM. THANKS.
