ZZR1400 - national PSB champion of 2008

PetriK:
Cool - finally everything I need on one internet site. I am very close to a the local 2008 national winner ZZR1400 dragrace team and hence any zzr1400 discussion will be welcomed (assuming that the topic ZX14/12 includes ZZR1400). On the other hand I promise to give feedback (to what I know and can be released) within timelimits I have on this topic.

Last season we run the engine with a fair shot of nitrous, never got the all motor prostreet engine running properly. The bike has amongst many other things:
- ARC
- KMS
- One stage nitrous
- Wired clutch
- Two batteries in front
- Slightly ported nitrous engine with 60shots one stage
- Highly modified prostock engine
The rider/engine builder Sami Vittaniemi virtually blew up an engine per race in the seek of excellense through out last season when trying out everything from conventional to unconventional. That paid off like the title says, a lot of competence was gained yielding to desired outcome.

Btw. tried to hack the ZZR1400 ecu (USA model K6), but unfortunately they have not included the backdoor like we have in suzukis.

When you say Prostock engine are you meaning, Muzzy billet?

ZX14 do not really have a separate block as busas have. This engine is very special, requires even a certain type of ignition plugs so that there is enough room for the very high compression pistons to come close to the head without the pistons hitting the head ;-). Gas ported pistons, of course, mtm. Only few persons have seen the head so not much info avail publicly about it - sorry.

halvefast:
I mean't this:



I guess not, so it must be all hand built by your crew,
how big were you able to get it in the stk block?

Bore and stroke?

How high is the compression, are you using a remote starter?

Just interested in what R&D is going on this this engine.
Thanks!

PetriK:
Some of the engine internals we would like to keep quiet of at least right now. Comp is anyhow well over 15 to start with. Local requlations say it must start from a battery, now using a special starter for this.

Here is another interesting angle, this is just on the other side of gauge cluster and behind the empty headlights. What in earh is a powerful vacuum pump doing there ?



or this clutch


and finally my favorite, composite fiber made stong and light structure of the bike, best seen on this picture.
