Default Forced induction engine build?

For winter upgrades, my builder and I have been talking about my options. We talked about doing RPW Thor or Bassani Pro Street exhaust, Quick Shift module, and nitrous plus upgraded clutch. After thinking about possible places to mount the bottle and thinking about how much I hated refilling bottles on my cars, I mentioned just doing a turbo. Turns out he is a Trask dealer and can get the kit for cost if he does the install. So...

If you guys were going the forced induction route, what (if anything) would you do engine wise to maximize the setup? Lower compression pistons? Beefier rods/rod bolts? The bike has to run on premium pump gas and I really don't want to run a meth/alky kit. Not necessarily interested in peak power but huge power from 2,500-5,500rpm.

2007 Hammer, 260 Metz, Shotgun exhaust, S3 cams, LED hidden turn signals, HID Hi/lo headlights, a few Ness accessories, S&S intake, PC3, and dyno tune.

I definitely prefer the Aerocharger kit (especially with the upgraded intercooler). I'll check to see what the difference in cost is going to be.

Imagine what 8 psi of boost would do for your bike.... instant, no lag boost.

I'm not a forced induction guy, I like naturally aspirated power, but for $5 grand the turbo is a good option. You could have your power ready to rock over a weekend.

That's exactly what I'm thinking. Turbo motors typically have a big fat torque curve and are usually pretty docile around town. I'm trying to avoid having to a bike that makes all its power above 4,500rpm and tempermental around town. How strong are the factory bottom ends of our engines in stock form? From what I've read it seems that 8psi is max with factory compression on pump gas. I'd like to know how far I can push it.

If you're not happy with the power at 8 psi (140/170), you should be in therapy. The stock bottom end is strong enough to handle that. Have you seen the crank in these things? The pistons will come apart before the crank fails.

You've got a good point. 140hp/170tq is plenty. I've seen pictures/videos of the internals of our bikes but never in person. I did happen to see this blog that shows what a built motor with one of their kits will put out...

Here is a post with dyno sheet about our system. Along with it is a dyno run on a Kewl Metals bike at our own dyno facility.

Greg and I have communicated from time to time. Last dyno I saw was well over 180 ft-lbs, but his is a 104" and far from stock.
