TB'S and airbox cbr 1000
 
hi guys i want ask you a question,did someone know if the TB'S and the airbox with the front ram air fit of the cbr 1000 on the 954? i saw one kit of ram air for the 954 from hotbodies (very rarely to find unfortunatey) that it was working with the same system,i mean bring air from the front like the cbr 1000. the TB'S is interchangeable with the TB'S of the 954? if it fit did someone know also if i can add the 4 more injectors?

You'd need the whole electronics, and you'd have to be okay with the tank sitting 1/2" higher, and the normal 1000rr intake runners wouldn't work, you'd need to modify it. The crossbar in the frame gets in the way.

the tank with the cover of the 1000 doesn't fit? for the intake it will be better make something like hotbodies was doing some years ago,or (maybe im telling something stupid) open two windows like it have the airbox of the 954
here it is the hotbodies ram air kit

Not even close. That one really can't be done unless you redesigned the subframe. It uses a tank that sits back and almost under the seat. Its too wide where the subframe mounts onto the 954 frame.

Your tank sits high on it because of the injectors and ECU.

See the crossbar? That's where the 2 pods would sit and the front of the air box would be. It won't fit onto the TBs and around the crossbar at the same time, so you'd have to modify the box.

The intake tract isn't that important. If you look at some '29 and '54 fighters who are running stock air boxes and they've welded the tanks shut and flush with the frame, they're making just as much power as they did before despite the fact there is a wall where the air box opens up. So you really only need to get the air box to fit.

And this all for 04-07 stuff. NOT 08+. Sensors are different, the FPR is on the fuel pump and there's no return line and the air box is even taller.


There was a guy on fireblades.org that did it on a 929 and just the air box and TBs gave him 7hp....on a stock motor - plus the throttle response and smoothness(?) of the dual injection and newer fuel map. So its definitely worth a go. Its not that expensive, just labor intensive.

that's why i wanted to made.. the guy that i told that he add other 4 injectors you know how he made? he doubled (i don't know if it's the correct word) the electrical parts of the injectors,he modify the airbox and he add the other 4 injectors that they open with signal that gave the gearshift..he said that the bike became a monster! i forgot he also modify the original TB'S making them more large of some millimeters. if i will find the photos i will post =)

Conrice 05-06-2015 09:21 PM

IIRC, he originally piggybacked the 1000 ecu on the 954 ecu, realized he didn't need the 954 ecu, and converted to just the 1000rr ecu. I don't know what he did with the gauge, but I looked into the sensors, and most, if not all, are the same (at least the important ones).

he worked on the 954 parts,had also 2 power commander,if i remember good there is a sound clip on youtube after if i will find i will share the link. the owner said that it was a monster

Conrice 05-08-2015 11:15 PM

Wow, that looks pretty. That's not the bike I was talking about. That looks similar to a zx6rr setup. Kawasaki wanted to keep the tanks the same, so the RR secondary injectors sat inside the air box like those seem to do (as the 636 didn't have secondary injection on those 03 04 models).

Marco Marfè 05-09-2015 02:45 PM

yes he made really a good job

Conrice 05-11-2015 07:56 AM

Here's the bike I was talking about.

Not as fancy, mostly OEM parts and slight modification of the air box.

He eventually bought a 1000rr gauge and ran just the 1000 ecu

thank you very much, im going to read :D

I have gen 1 Busas 46 mm tb:s waiting in the garage. Next winter i'll get them fitted :) They need little machining that they don't interfere with the 954:s head. I was planning on using Schnitz racing 10mm stacks with them.

Conrice 05-16-2015 06:16 AM

Can't wait to see how that takes shape!

Anymore thoughts of e85?

Marco Marfè 05-16-2015 08:22 AM

mika you are always working on your engine right? i think you will never stop ahah

mika_u 05-18-2015 04:05 AM

Have to see will i use RE85. Probably if we will bump the compression a bit but well see about that. The head has to come of first and then will see what are the changes :) But now i'll just ride the crap out of it.

Marco Marfè 05-19-2015 11:15 AM

on your actually engine you are still using the original fuel pump? one guy told me that i should use the cbr 600rr fuel pump because it's more better than the 954 pump..he told me the same also about the injectors..any opinion?

I'm using the stock fuel pump and injectors but i have a set of Busas injectors waiting with the TB:s. I doubt the pump is any better and i would imagine that the injectors are smaller on 600RR.

Conrice 05-20-2015 10:32 AM

I doubt the pump is any better.

Maybe it's a little stronger because it has to deliver fuel to 8 injectors at really high rpms, but you wouldn't see any benefit to it, with a 954 rail and FPR. The 04-07 pumps are the same style as a 954's as well. The only real benefit I could see is that they're slightly newer...

As far as the injectors, I'd figure the 1000 ones to be more similar, or an upgrade. You'd have to see what flow rate and nozzle configuration they have. They could be the same injectors. And, are you sure the top injector is the same as the bottom injector???

I do know the 954's injectors are an upgrade from the 929's because of the nozzle, so it stands to reason that Honda might have upgraded again, but with the dual injection system, who knows. It may not be a viable option at all.

And you need to be careful with swapping injectors since there's no o2 sensor. You need injectors that have a really similar flow rate, and operate at a similar pressure. The nozzle would be where you'd see gains.
