Well I trained at the Southern Alberta Institute of Technology, there we had a Cessna 182 and 320, a King Air (not sure which Mk), 2 Bell 206'*, and Alouette 3, and a North American Harvard (same thing as a T6 Texan)...

Then my first (and only, before I left the industry) job in the industry was here http://www.lancastermuseum.ca/. I worked on the Avro Lancaster, DeHaviland Tiger Moth, Bristol Bleinham, another Harvard, Boeing Stearman, a Czech L29, and a Fleet Fawn.

Are you an AME? Or I suppose it'* some different designation in the states, which eludes me at the moment....

All your questions are answered in Forced Induction I'll move this topic there.

You don't need the Series 2 puller. Ours are keyed, not press-on. And they're steel. So you can use a 3-jaw carefully to remove it without damaging things.

I'd suggest you buy a stock-length gatorback belt (helps to prevent belt slip on the smaller pulley) so you can use your existing belt with a pipe wrench to loosen the nut on the stock pulley for removal without damaging it.

Use a stock length belt and an oversized idler pulley. It'll give you better belt wrap circumference.

i bought one of the zzp pulleys from zooomer and it is top notch quality. its made by the same company that makes his series 2 pulleys. i dont doubt the quality of pulley boys though, but for the price the zzp pulley is $50 and the pulleyboys pulley is $60. my personal preferance would be zzp, but thats just me.

2.8 to 2.5 will net you ABOUT 20-24hp and 35-40 ft/lbs of torque. You'll get into boost quicker also, so throttle response will be much snappier.

3-jaw is a gear puller. You need that or a pulley puller. If you're not familiar with this, hook up with Gordy or Harofreak....or any of the other MN guys.

Isuggest doing a 180 stat and a cooling fan switch override mod at the same time...parts=about 20-25 bucks and it takes about an additional .5-1 hr to do depending on where you mount the switch, the thermo is super easy just get some good high temp rtv and clean it up good, the switch info is on my cardomain site pretty easy to follow.

And a SC outlet gasket, red gasket maker, carb cleaner, TB gasket, etc. You can't do this without pulling the SC unless you want to invest a couple extra days and disassemble pulley brackets for your accessories. It'* not worth it. Pull the SC.
