Did you go dual pulley all together, or did you do one at a time? If you did 1 at a time, how big of a difference is it?

I installed them about a month apart but I got the tune first, which definitely made its presence known. To be honest, I really didn't feel that much difference after that with either one. But like I said before, I can't ever really take advantage of the full power band. All I know is that 100mph sneaks up on me quick and keeping traction off the line is pretty much impossible.

Oh ok, I have the upper pulley, 200 cell cats and tune. And I'm in the process of installing methanol for cooling. And I was thinking of doing the lower pulley next. But there's not alot of info out there on it for the v8.

On theV8, OEM upper pulley is 66mm vs 60.5mm for the Mina Gallery pulley. The Oem lower pulley is 162mm and the Eurotoys pulley is 180mm.

I have those exact pulleys (on a V6). Running both pulleys at redline won’t do any harm to the engine but will run the supercharger beyond the adiabatic efficiency range causing a precipitous drop in power near redline when the engine gets hot.

So I started off with a Rica Tune and the upper pulley from Velocity AP. I had an itch to get more, so went with EuroToys lower pulley, but I went with Velocity AP's Tune. Eventually I went with Axle Back Quick Silver Exhaust, and High Flow 300Cell CATS, plus a bunch of other things along the way. Been on this setup for probably over 10,000kms (~6,200miles) and I push it hard, whenever I get the opportunity to. Many trips to the dragstrip and lots of freeway pulls. Mind you I live in Canada, and the hottest of days in the summer are ~32C (~90F), so I haven't gone with any of the additional cooling ad ons, such as: exchangers, or higher flow pumps, or Methanol/ water injection. Today for example is 21C (69F). High Temperature isn't as great a concern as it is in warmer climates.
Below is a helpful link of my journey:
This is where it started
So far I have no concerns with dual pulley setup but I didn't go bonkers with my setup, meaning:
- Upper Pulley is Velocity AP's and there are smaller pulleys out there (Mina, etc), this is an improvement on stock, but not too crazy
- Lower Pulley is Eurotoys' and I believe Velocty AP's lower pulley is larger than Eurotoys' pulley, again an improvement over stock, but I didn't go too crazy
- These details were sorted from my own research, and some it can be found in some of Unhingd's resposnes in other threads
- The thought process is even though I'm spinning the supercharger faster than stock, I haven't truly gone all out. This is my sad way of justifying it to myself.
Feel free to PM me if you have any other questions.
