Lethal Performance is proud to announce that we are now WD Distributors for Innovators West. Innovators West are the manufacturers of high performance balancers and the maker of the well known 10% Overdrive Pulley for the Shelby GT500.

We now have in stock with same day shipping the 10% overdrive pulleys along with the belts and the bolts which help the installation and removal of the balancer.


Innovators West now offers a complete replacement balancer for the 2007-2009 5.4L Shelby GT500.

Ford redesigned the factory balancer for 2008, making it much lighter than the 2007 unit. This balancer is even lighter than the new 2008 part.

-The supercharger drive section of the pulley is enlarged in diameter by 10%, for a 3-4psi increase in boost.
-Improves performance by reducing rotating weight and raising supercharger boost.
-Great for increasing boost on aftermarket blowers like the Whipple 3.4L, Ford Racing TVS and Kenne Bell blowers.
-Available as 10% OD
-10% OD balancer requires slightly filing of casting for clearance.


NOTE: A larger belt is required for proper installation of this pulley


Feel free to give us a call or place your order online and your Innovators West Balancer will ship the same day guaranteed!

Thanks for all of your support.

Jared and the Lethal Crew!!

Here's a great writeup of the installation compliments of our good friend Justin@VMP Tuning.

This article will cover installation and removal of the GT500 crank dampener
(balancer). On the GT500, the balancer is all one piece and serves as the
drive pulley for the 10rib SC belt and 6rib accessory belt. I will go over
pictures and differences between the stock 2007, stock 2008, and aftermarket
Innovators West balancers.

The stock 2007 GT500 balancer is extremely heavy, about 27lbs. The design
is borrowed from the Ford GT. Due to its weight, it is possible for this
heavy balancer to strip out the keyway and/or crack the crank snout. Ford
re-designed the 2008 GT500 balancer and made it over 10lbs lighter. Ford
Racing requires the use of the 08 balancer on 07s, if you want to have the
TVS blower upgrade installed by a dealer under warranty. Anyone that is
racing their 07 a lot or has an upgraded blower should consider installing
the 2008 part or one of the aftermarket dampners out there, especially if
you have nitrous. When you spray N2O it results in a sudden power increase
and sudden acceleration of the engine, which will put a lot of stress on the
crank keyway, a lighter balancer will help reduce that stress.

This picture compares the 07 and 08 units, you can see all the extra
material on the front of the 07 part.



This picture shows how the 07 balancer is solid all the way through the
middle. You can also see how to mount the balancer removal tool with three
M10 X 1.5 X 80MM long bolts .



You can see how the 08 balancer is open in the middle (much less material).
A special ford tool is specified in the shop manual to remove it, but I
heard a regular 3 jaw puller will work too if you grab it by the little
"wings".



For VMP Tuning's 2007 Red/White GT500 I decided to go with the new
Innovators West 10% OD crank pulley. I am running the Ford Racing TVS
Supercharger upgrade, so the 10% OD pulley will get me several more pounds
of boost. I have already put the smallest upper possible on my blower
(without machine work) which is a VMP 2.65" stock look pulley. The IW
balancer is even lighter than the 2008 oem part. The 10% OD balancer comes
in at around 12lbs and the stock size balancer is around 10lbs. The IW
balancers are SFI certified, which you'll need to be legal if running 10.99
or faster at the track.

Currently there is only one aftermarket GT500 balancer on the market (as of
1/08) and it's made by www.InnovatorsWest.com Several vendors carry it.
Some are claiming that it's a "4lb lower", but in my experience the amount
of boost increase you see varies depending on your combination. On my TVS
blower which already had a 2.65" upper pulley, I only saw about 3psi peak
increase. When you work out the pulley speed math the 10% OD balancer is
roughly equivalent to a 2.7" upper pulley, which we know yields about
2.5-3psi. Maybe if you had a KB or whipple that was right in the sweet spot
you could see a 4-5psi change in boost, but those blowers need a lot less
RPM due to their large displacement.

The stock GT500 setup with a 3" upper pulley and 7.1" balancer results in
blower RPM of roughly 15,300. A 2.60" upper will get you 17,750 RPM. The
10% OD balancer alone will get you 16,900 blower RPM. Both combined add up
to about 19,500 blower RPM. All of these numbers I'm quoting are based on
6,500 engine RPM.

On my TVS blower I saw about 18.5psi in the midrange and 19.5psi peak with a
VMP 2.65" upper and IW 10% OD lower. (more on that in another article).

The IW stock size (7.8") balancer is shown here:


Here is the IW 10% OD, you can see the larger 10rib SC pulley in the back:


Onto the installation...

Disclaimer: always follow Ford and Innovators West instructions for
installation and torque specs.

While somewhat involved, don't let the install intimidate you. With some
normal shop tools and an afternoon anyone that is mechanically inclined can
knock this project out.

First thing you'll need to do is unbolt the intercooler reservoir and
coolant overflow tanks, use an 8mm socket with an extension on it. On my
car, able to do this without letting ANY fluids out. I disconnected the
small "Tee" line from the overflow tank and stopped it off on both ends, and
then tied it up under the fuel rail crossover. I was able to lift up both
tanks and use a bungy to hold them on top of the motor and out of the way.

While you've got that 8mm socket out there is a bolt on either side of the
radiator fan that you'll need to remove. Those two bolts and clips are what
hold the fan to the rad. Disconnect the electrical power to the fan. Once
you lift the fan up out of the clips you can twist it sideways and get it
out past the rad hoses and ac lines. It's a little tight, but its possible
to remove it without disconnecting any lines.

Now we've got room to work.



[size="2"][b]It would not be a bad idea to lay a piece of cardboard up against the rad
for protection.

That AC line looks like it will be in the way, but I found it pretty easy to
work around.

Both belts will need to have the tension taken off of them.

The supercharger belt comes off by inserting a 3/8" ratchet into the
tensioner on the passenger side and pressing down
