He isn't running a pulley.

So how do you measure the boost? Dyno?

Boost gauge. Connects to the intake manifold and tells you how much pressure is built up by the SC. Higher boost means higher HP, UNTIL intake temps get too high and you get detonation, retardation and hopefully not meltation.

So what's the estimated power gain of installing 15% and 16% pulley? Does it really reach 20 to 30 HPs?

I've got an Alta v2 17% and I love it. Although I HIGHLY doubt it's a 20/30 hp gain. Was a bit of a pain to put on, but thats just cause I wanted to make sure everything was perfect. Been on about 6k now, not one problem.

I use my own pulley when I do installs. It's stainless steel so it will last forever. The hole in the center makes install easier if it's your first time. 4 clamping bolts. Similar in design to the other pulleys, but how many times can we reinvent the wheel.

Realistically your gain will be about 15hp, give or take, but it's across the RPM band.

Do a search for "KMT Pulley", it's a pulley that is made in eastern europe and is sold through ebay for something like 60 bucks. Somebody bough and reviewed one, and surprise surprise it was just like all the others.

Actually it's made in European Union.
