Back from Popular Demand!

WE are happy to announce it's second group buy for the underdriven lightweight crank pulley for the VQ40 platform.

WRP Technology is proud to offer the only lightweight underdriven Crank pulley for the VQ40 platform. Featuring a 14% underdriven ratio, this crank pulley weighs 6 lbs lighter then stock. This is an excellent choice with no sacrifice to your current accessories output. It comes with a stainless steal collar to prevent wear against your crank seal, it is made from light weight T-6061 Marine grade aluminum, and it yields 8-12 wheel horse power and torque gains.




For this group buy, we are going to offer a 20% discount with free shipping. Normal retail is $249.99 plus shipping, but this group buy price will be $200.00 shipped to your front door.

We are seeking 18 buyers to complete this group buy, though in order to be added to the list, you will need to send a pre-payment of $200.00 via paypal to [email protected]. Canadian buyers, please add $25 USD for shipping.

We also accept Mastercard and Visa for those who chose to not use paypal. Only customers who have paid will be placed on the order list - so a payment is needed to confirm your spot.

Please include with your payment the details as well as your online screen name and which forum you are from. This helps with tracking results as well as keeping a clear communication from the forums to emails - Understand email is the prefferred method of communication as Private Messaging is sometimes confusing from forum to email.

Cause less parasitic drag from the OEM crank pulley. Thus freeing up more horsepower. Its also under driven as well, meaning a smaller circumference.

What it really does is slow your water pump, fan, ac compresssor and alternator down. You do get a few more hp available at the business end of the crankshaft though, but having a slower water pump and fan in the desert southwest might be a concern.

we did a side by side comparison of the underdriven crank pulley against the stock setup and found no difference in engine temperature, voltage, or power steering power at idle. I did research on the various components on the VQ40 and found they have a low idle range of about 450 RPMS, which still operates within the factory requirements.

Ok, im a retard. What the heck will this do?
This pulley is something that goes on your crank in the engine - it will remove the stock one and replace it with this one.

The reason why it's better is because it's 7 lbs lighter then the stock one and make the engine work less to turn it. This reduction in weight turns into a transferrence of power to the wheels.
