Roush TVS Pullies
Wow, Tim! Great numbers! I still haven't sent my snout off to get it machined yet. I haven't had time but plan to soon. I had a 2.7" pulley built that's sitting on my toolbox ready to be installed. I can only imagine the difference. Still on stock bottom end?

you are still 6 rib right? i get belt dust on top of my water pump but as far as i can tell i make 13-14#s and doesnt fall off but the f'in needle of the boost gauge does some crazy vibration and its a blurr. could be the open cutouts rattling the **** out of the truck hahaha. if the motor lasts through the year i think im going to put an OD balancer on, e85 and spray it trying to go 10's. balancer should net me somewhere around 17#s with the 2.8 pulley.

Well i should update this thread as to help possibly anyone who might search this topic down the road. Old news to most hahahahaha.
Truck makes 12 psi with 13-14 psi spikes.
Using an Innovators West overdriven crank pulley with a 2.6 blower pulley.
My combo may vary from others, remember boost is a measurement of restriction.
Truck made 562 at the wheels thru a t case and 4L80e on a 90+* day, easily will put down 600 with a touch more timing and cooler weather.

I just did mine with a die grinder on the truck. When I got my pulley I took a little bit off of that too. It came with a lot of meat on it. I don't think you need to remove it and take it to a machine shop, but if you feel more comfortable, you can.
