which torque booster

[TXSVT1]

In the market for a torque booster and wondering whos is the best performance and price wise. I'm currently running a v3 sI unit with a boss im. Don't know how much boost since I don't have a boost gauge. Thanks for any input

There's only one torque booster, beefcake makes them. Unless you're going to make your own

My V-6 with a Eaton M-90 supercharger picked up close to 30 lb.ft. of torque by swapping the 2.8" pulley to a 2.4" diameter.
But you really need a boost/vac gauge for tuning and troubleshooting.
