Quote:I'm thinking 200 HP at the rear wheel is doable with a setup like this (along with the necessary FI mods etc., of course).
I've never seen a turbo application in which the builder experienced more than 100% increase in power, nevermind 167%.
Unless you're talking about with nitrous-oxide injection as well, in which case, I still think that's high.
Typical returns from a "safe" turbo application (on an automobile, which is water-cooled, which provided many advantages over the air-cooled bike we're dealing with), are usually somewhere around 50% increase in hp. So, you could expect something in the neighborhood of 112hp at the rear wheel of the CB. With a 50 shot of nitrous, you're still only looking at about 150hp, which is less than every major liter bike currently manufactured. The nitrous shot would be dangerous, IMO, both from a mechanical standpoint and from a riding standpoint. I would never put nitrous on a motorcycle.
The turbo lag thing has been mostly mitigated by modern impeller technology and design, AFAIK.
