Actually, no, there was no "de-restricted" version available. The Direct Connection computer INCREASED boost.

This is why big power increases are relatively easy on ANY boosted engine...like the H2R.

This is getting to be a circular argument here.

There are many other factors for increasing a engine from 200 HP to 300 HP than just changing the "chip". If it was that easy, it would be done all the time. You are more than welcome to keep increasing the boost on your 200 HP engine until it blows itself to smithereen...well before it reaches anywhere near 300 HP.

Depends on the engine. There are some that will scatter just above the stock power level...and there are some that can come close to doubling the factory power with no ill effects. (Offhand, a Buick Grand National could manage 425HP-stock was 245-on stock internals without a problem.)

And do you think the people who would try for a 300HP street bike would care about longevity?

No they would not, but that was not my point at all. My point is that you simply cannot take a 200 HP engine and turn it into a 300 HP engine by plugging it into a laptop as another poster asserted. The difference between the race ECU and the stock ECU for Ducatis for example is virtually nil in terms of HP. It simply smoothes out the bike originally mapped to satisfy the stringent EPA standards. On my Hypermotard, even if you add the ECU, cam, full exhaust, intake; big bore kit with high compression piston and bump in displacement, you would be lucky to see 30 HP increase....and you probably spent about $5,000 in parts alone.

You are STILL not understanding: your Ducati HAS NO BOOST TO TURN UP! That is the key!

I understand that. But do you really think the difference between the engine/trans of a $70,000 (my guesstimate) racebike and the $20,000 (my guesstimate) street verssion of it is going to be just boost??? :boat:

Not to derail the thread but that GN/GNX engine was a great engine; probably the only good one GM made back then. It's hard to imagine that the same company that thought making a diesel engine out of low compression 350 Olds gas engines was a good idea, created that motor during the same era.

Probably not...but how many of the hard-part changes will affect POWER (milder cam, lower compression), how many would just be for emissions (muffler, catalyst), and how many would be only for durability (sodium-filled valves, thicker piston tops)?

I know motorcycle engines are much higher-strung than cars, but if you have never owned a turbo car, you cannot understand just how easy it is to make huge power. (There is at least one nut in Missouri putting down over 1000HP from a 2800cc 4-banger--a 2-valve 70's design no less--his Mustang will show taillights to many sportbikes at the drags!)

Increasing boost on a supercharger is nowhere as easy as it is on a turbo as you well know; and even more difficult on a motorcycle due to size constraints and limitations.
You increase boost, you are gonna have to do the other stuff. Not arguing that it cannot be done, but it will take bucks, time, engineering, and skills. Nothing like the science fiction of plugging it into a laptop, and voila instant 100 HP.

Not as much as you think...you do need to turn up the fuel in proportion to the boost, which is quite simple (easiest way is to bump fuel pressure). It may not be perfectly optimized...but it will make power!

How is the blower driven?
