And to finish, finding a chip !


Do you need to modify the frame to use the Shower injectors, I thought that would only be required if using the 748R or RS larger capacity airbox, which is why I was hinting above about a custom airbox that would allow the use of 748R throttle bodies in a Bip frame. Your right about the inlet manifolds and inlet side rocker covers.
The IWP069 Pico injectors in the R throttle bodies flows 491cc/min quite alot more than the existing ones, but possibly still something that could be handled by the existing chip and power commander.

But with all these issues I would be considering using the existing throttle bodies and ECU and changing the injectors for ones with a higher flow rate such as those I already mentioned, if its only a matter of meeting the fuel demand for the 955 kit and cam.
But to get the maximum power then you may have to think about the 54mm throttle bodies

Yeah, at the beginning I was thinking about bigboring std TB to 54mm and add high pressure fuel pump (4,5 or 5 bars, have to see). For ECU, idea was to add PC III USB.
Changing the injectors wasn't in my plan but now I think it would be a full good package.
My aim is only to have an injection fitted with the kit and cams.

But when looking for ideas, I saw many other solutions.
Now, it's clear, I have to keep my first intention.

Thanks a lot guys.

Are you sure of that?

Nope, hence me asking the question.
Out of the 5 frames I have only my 996 doesn't have the Kyalami frame and as I'm happy with the way it performs with its standard twin injector throttle bodies I haven't looked into fitting the 748RS throttle bodies I have to it.

Just fit a Corse fuel regulator for the higher pressure and one of Brad the Bikeboys chips and you should be fine.

Don't worry this question was only for my personnal knowledge.
My 2 options are:
P1: high pressure fuel pump (already have it) and rebored TB to 54 (for the fun). Perhaps bigger injectors (not sure at the moment).
P2: P8 and SPS injection (have 1 opportunity and not more work in rebuilding engine)

Thx for all infos you gave me.:)
