i can see the turbo spooling up on turn and add unnecessary power and the person wiping out... just like many turbo cars (not all) the ones that are boosted for high numbers are more for drag than circuit and 180hp on a bike is alot

Thanks for the suggestions. I have pulled the motor and it is going to the engine builder. We are planning to do some major stuff.
Balance and lighten the crank
Carrillo rods
high compression pistons
major head work to up the compression
port work
ignition work/mapping
ram air
etc.
Wish me luck. Maybe now I can win more easily.

+1.. I think it would be a ****en blast. Sure, you would have to adjust your riding style.. But would still be a blast!!
[edit:disregard this part, I'm late as ****]To aswer the original question, I'd also say;
Full system(obviously)Raise compression, cams, PC3 to take adv of your new mods, stroke and port the head if you have the $$$$

As far as Tubo's go in general , they can be configured to perform in slightly different ways ... A std engine running low boost will give the power prolly and still be able to be used with relative ease on twisties ect ...
Std higher compression engines tend to need way less boost to produce a very usable high horse power and still have power bands that start lower in the rev range ...
These types of setups are fairly good for normal use in the twisties ect ... because the Turbo lag is minimal and the power starts low still and builds fairly evenly ...
Very high compression engines are not really suited to very high boost because of the extreme wear and possible failure of the engine under the loads that can be produced from high boost and high compression combination's..
....compared with lets say a modified lower compression engine with high boost, that produces way more power up high in the rev range and the power tends to come in with a massive bang...
These setups are very hard to use on roads that are twistie ect because the lag is much harder to avoid on specially modified engines that have had the compression lowered for ultra high boost use making them near dangerous to use like a normal bike run hard around a mountain road ...
So it really depends on how the engine and turbo are setup and what they are setup for , as to how useful they will be under certain conditions...

This is why dished pistons and a Lower CR are what you need before you turbo anything, drop the CR down to 8.5:1 land.
The work he is doing to his motor will translate into some very very nice Gains, the CR boost from decking the head, the port job and cams, and the lighter rods and rebalanced crank should be somewhere in the 40hp range. I plan to do similar work on my 2k 929RR this winter, shes fast already, but just not quite fast enough!
