Turbo CBR250RR track bike

[studricho]

Do you think that it would be quicker around the track or not?

Depends, what's faster, a unicorn or a clean pair of Ontik's undies?
(none of the above exist)

Judging by the studman's av, I'd say he's made inroads with dave's turbo tracky.

[studricho]

Yes and No. Still same work to be done, but I do own it.

I was having a debate with a friend that said that turbo track bikes don't work. I agreed that a larger capacity turbo bike would be useless, but maybe the 250 might be the right mix that can be useful on the track.

Comments?

Worst case scenario it'll ride like a 125gp bike. Enough power to spit you off when it hits band if you're uninitiated.

What are we comparing it to though? A worked cbr250 tracky or a roadbike? The weight of the turbo could easily be offset with lightening efforts, there's a small increase in reciprocating mass but it'll still be easier to muscle around than a 600..

I'd say it'd be quicker, but can't say without riding one....

and I thought it was supposed to be a secret.

it will definetly ride different... you will always try to keep the boost on to have a good response on corner exits. it might be an idea to tune up an anti lag system.

but its getting more and more complex... you might as well convert it to efi to aloow tunability... otherwise its just going to be rough and not many options.

I thought you were trolling Rich Ok, the only reason I see it possibly being slower is if it has truly horrible lag. Even setup well it'll be harder to ride fast, but ridden well it should spank the NA.

i would also definetly use a Dan Culkin valve on the manifold also.

And the weight thing, a 250GP bike corners faster than a motoGP bike don't forget.

It'll come down to whether or not the power offset will balance out the weight increase. Or fit better suspension.. but at that point you get dangerously close to having to ask yourself why bother with a cbr250 since there's so little cbr250 left!

-1 to the antilag, assuming stud would rather not be replacing his turbo well, probably at all, anti lag is probably not a good option.

i think it'll be just like any other new bike you wanna track, you'll need to get used to it and learn how to get the most out of it, but once all the bugs are sorted and your getting consistant lap times i think i'll be quicker, the extra acceleration and top end speed will outweigh the low end off boost riding i think.
