No additional info to add (I think this is a great idea BTW). I've lots of questions instead :), the answers of which might be useful to keep with the TB info.

I've got TB's from a GSXR600:

There doesn't seem to be anyplace to mount a fuel pressure regulator on the fuel rail. Where is it normally on these things?

The TB appears to have a built in MAP sensor, plumbed to all 4 TB's - is that what it is?

The ECU controls the secondaries, so that big block on the side is a stepper motor of some kind? What's this for, higher air speed for low end torque? Any idea how the ECU controls it? Analog, digital, what engine conditions?

Don´t know but anywhere between the filter and the rail will work but I would modify the original rail for fuel in one end and fuel out in the other, blank of the original inlet or use it for ex. pressure guage. This would cool the injectors. I have done it for a friend and here is some pictures of it.

Yes, it´s the Suzuki MAP.

Not a stepper motor, it´s only a magnet inside with a coil on the outside.
It´s for better throttle response in low revs, Reverse polarity makes the magnet open or close the butterflies and a secondary TPS for feedback so I would call it Analog. IIRC it´s controlled by a tabel like the injectors, can´t find the link about that.

2000 Honda RC51

Postby mikesb » Mon Feb 28, 2005 7:40 pm

Make/Model: Honda RC51 year: 2000

Number of Tb: 2, 2 injectors per TB
Inside Diameter: 48mm
Center-Center (left to right from behind): 200mm (TB's are not parallel)
Overall Length: approx 400mm
Outside Diameter (intake): 60mm
Outside Diameter (filter): 70mm (not sure how filter fits)
Separate casting: Yes, TB's are independent, mounted to linkage bracket. Modification needed of fuel pipe and linkages to change spacing.
Injector Make/Model: ????/????
Flow Rate (43psi/100%): 335cc/min, 13Ω , ??mH
Fuel Rail: Alu casted, 1 per injector, joined by solid fuel lines

Comes with MAP, fuel regulator, TPS.

Has a manual choke mechanism synchronized to both TBs. Not sure how it works - fast idle bleed perhaps? Sure looks like it.
Separated, the TB's can be mounted 200mm on center parallel in their original orientation.
Flip the TB's in 90 degrees so the linkages are touching, they could be 130mm c/c.

Just took some measurements on my TB's.

03' GSXR 1000:

-Tapers from 50mmID to 42mm ID.
-OD at inlet end is 53mm.
-90mm overall length, +/- 2mm.

Pic without "secondary" butterflies and fuel rail:

Hope that helps.

I have bought a TB setup from a 2002 Honda Fireblade CBR 954. I plan to fit this onto my 1966 Singer Chamois (Hillman Imp) sprint car - 930cc, OHC, full race tune, ~90bhp plus.

My question is how do these TBs operate at idle? The butterflies appear tightly closed when the throttle cable is slack. Is there a bypass air supply? If so, does it need to be closed when off-idle or at wider throttle openings? That being the case, how can I get a MegaSquirt to control the idle bypass?

I hope someone can point me in the right direction! Thank you in hopeful, eager anticipation.

I don't know if these will be the same, but on my CBR929 TBs there is an airbleed valve built into each body. They are all operated by a long shaft with 'fingers' the press each valve. There is a thumbwheel adjuster to set idle speed and a vac thing that also operates on it.

Should be fine to leave these open when off idle, but not sure the best way to implement high idle when cold !

Unless you can use a simple solenoid valve to supply vac to the vac thing to increase the idle ??

Spag,

You might be onto something there, with that vacuum and solenoid idea. I need to have another look at the TBs. Mine also have the shaft with the fingers on operating an air bleed in each barrel. There is a waxstat for cold start air bleed. Maybe the latter could be retained for cold start with MegaSquirt (given a supply of engine coolant), or a solenoid implemented, suitably mounted. Hmmm. :idea:

I'll keep the forum posted.

Waxstat... I didn't spot that, is that the thing I think is a vac jobby, with 2 hose fittings on the end ??

Oooo, just taken it to bits, and yep it's a waxstat. :shock:

With all the other vac plumbing I got confused.

Easy for the cold/warm idle thing, but not so good for idle control - sorry :(

Spag,

What I meant was remove the waxstat and graft on an idle control actuator from a different vehicle. Somebody somewhere (Imp Club forum, I think) mentioned a Ford Fiesta IAC actuator. I guess that's the stepper motor.

I'd need to check that an IAC control function is available in MegaSquirt, though. I don't think MS can cater for that yet.

The alternative is to set my idle a little high - maybe 1200 rpm - to allow for variations with load, etc. Not ideal, but not my main transport at the moment, so should be okay. Besides, my Webers don't have any automatic idle control! :lol:

2003 Kawasaki 636 TB and injector info

Postby sportbikeryder » Sun Mar 20, 2005 7:49 pm

Did some testing and measuring (not to mention some initial starting, running and tuning with MS :) ) this weekend with the following results:

KAWASAKI
Make/Model: ZX6R 636 B1
Year: 2003
Overall Length: 90mm
Outside Diameter (intake): 52.6mm
Outside Diameter (filter): 50.8mm
Injector Make/Model: "BOSCH 280031V"
Flow Rate (45psi/100%): 2 tests completed on two different injectors. #1: 960cc in 235 seconds =~245cc/min #2: 690cc in 166seconds =~249cc/min, therefore, roughly 245cc/min.

GSXR 750 bodies

I fitted a set of these to my 2.3 litre Escort RS2000 and used Emerald management.

Now fitting a set to my 1989 FZR1000 EXUP fitted with IHI turbo.

38mm CV carbs Vs 46mm throttle bodies

Image

re-spaced to suit Yamaha and new billet fuel rail made for supercharged Jag V8 injectors.

Image

End body shortened and adaptor fitted to allow GM TPS to fit

Still need to make the loom for Megasquirt though :oops:

exup turbo: Im intruiged as to how your gonna get them TBs to fit your inlet rubbers on the exup, cus the external diameter of them @ inlet side is WAY bigger than your CV carbs.

Im planning on putting MS on my GSXR1100, but a little concerned as to which ones to use, becuase of the limited size of inlet rubbers.

I'm using GSXR750 inlet rubbers which are not much bigger at the cylinder head end than stock exup. I made some adaptors and fitted them to my original inlet manifolds, then matched to the GSXR rubber.

Still plenty to do, but I am winning :)

anyone have a flow rate for this yet? would be much appreciated!

Cheers,
