Low Boost Turbo Feeling

I posted this in the BKING section.. but it doesnt get much traffic... and maybe near zero turbo traffic.

Can anyone describe the feeling of riding a Bking (or I guess busa) with low boost (like the RCC bolt on kit).

I have turbo cars and at high elevation they are hard to beat. Turbos first bring back most the power lost by elevation, and then boost above that. In general where I live atmospheric pressure is -3psi from sea level. So a 4 psi kit is making 7 psi over "atmosphere" so it is like going from no boost at sea level to +7psi when compared to other bikes. So think of it like a 200rwhp liter bike, makes 160rwhp here. A 240rwhp turbo Bking at 4psi would make around 230rwhp here (there is a slight heat loss from more compressing). So it would "very fast" here.

But what do they feel like other than "fast". I have old school single bug turbo, low compression cars. I have new modern ones.

The old school are feel like.... wait....wait... wait... wait.. something is happing... holy crap tires just broke loose.... big turbo spikes. They are much harder to drive in corners because it either needs to always be on boost in corners or off boost. The steep boost ramp can cause havoc in corners and breaking traction.

New school twin turbo with factory anti-lag make a turbo car feel almost like a N/A car, just more powerful and more torque low.

So just wondering do the turbo kits have the "boost spike" or are they smooth on boost curves? Or at least smooth boost at speeds that public roads in the mountains can be ridden at?

I am really debating on buying S1000RR or putting turbo on BKING (i would keep Bking even with buying another bike).

To keep "keep up" with an S1000RR (lower weight and good power) a bking here would need about 198rwhp. The turbo kit beats that by about 30hp. (sea level with my weight a bking would need about 245rwhp). (or course all of this is ignoring aerodynamics)

I just dont want to deal with huge turbo boost spikes on a bike.
 
Have you ridden an SR1000rr to compare it with the b-king? The one that is more fun to ride as is, regardless of which is faster, is what I think should be the deciding factor.
The turbo experiences you described seems to indicate a larger than needed turbo which takes longer to spool up and respond. The general rule is to get the smallest sized turbo that fits your application which allows quick boost hits and max use of available boost. And the smaller turbo allows better throttle control through corners but ya gotta remember it's all about how you personally can handle the throttle control.
Funny story, was in relaxed slow cruising mode thru Mt St Helens park, and while slowly passing even slower HD riders, boost suddenly kicked in right before a corner, I had to very quickly sit up and lean way over to make it thru the corner in one piece...that's living the turbo life LOL
