Setting up ITB's on a 308

I'm reading it all Luckydynes, keep them comming!
My guess however is that in general the owners here are not so into technics that go beyond belts

 

I'm keeping track too. Great work Sean.

I'm just awed from your awesomeness.



ok, see I said it.

 

Sean,
Great thread, just found it. Don't know how I missed it earlier tho.

 

Hmm..how did that thumbs down get in my quote??


Please disregard that Sean.

No worries Pizzaman ... I thought my sense of humor had rubbed off on you .

I started thinking about my air box. I'm not sure I need to make something free form out of fibreglass now that I can see what shape will work. There's almost room for one big air cleaner or 2 oval air cleaners in the box. I might wait until I get the motor in the car to really finish this now I have a clear game plan. The deck lid clearance will be tight and I want the box as big I can make it.

cheers

Thats not bad.
I had thought of something like that too but i went with a "little mod" on the rear bonnet instead.

That will look excellent!

I will do that if I have to but I hope I have enough clearance.

cheers

 

I guess you're going to leave it open like that?

It wouldn't be that difficult to fiberglass ove the mesh and blend it all. I thought that's what you're plan was but looks like since it's back together you're going to leave it open. I'm just using the mesh as a "form" but because the box can be pretty much square I think I'll just make it out of sheet metal.

cheers

 

so which Japanese motorcycle did you swipe the throttle bodies from ?? Looks like a Cool setup...if I ever get my ECU working I may want to do this Mod...

andy

 

Suzuki Hayubusa.

 

Nice drysump tank in those pic's , you never showed us that ??? or is it just a catch tank ??

 

In the car it's just a catch tank ... my ITB motor on the engine stand has the dry sump on it. I'll take some pics of all that and update that thread or keep it here?

cheers

 

I'd love to see an update on your dry sump setup - that's still on my list of to do's on my QV over the next few years. I guess in the other thread would be best, but either way works.

Don't forget to update the gearbox wear thread while you're at it. My 5th to 4th downshift takes a hair to long to synchronize.

 

See we do pay attention !! How are you doing with the gear cones ???

 

Yeah, for now I'm going to leave it like that. Once I get it back on the car it will give me a better idea of what I have to adjust. Rain is the biggest issue if I ever get caught in a storm. Air flow?? I won't now yet.

 

Bump,, we ARE WATCHING YOU.....
(feel better..)

Cheers guys ... thanks for the posts.

I finished up the fuel rails and lit 'er off again yesterday. I also made up some new throttle linkage bits. I'll update the dry sump thread when I have some time. I'll try and take some video today. I found a couple of cracks in the headers yesterday so I need to fix that and then I think I'm done with engine stand tuning. The only other thing I might want to do is hook up an actual throttle pedal to make sure it has enough cable travel to actuate the throttles to 100%.

cheers all

couple more of the throttle linkage evolution. I don't know why but I can just stand there for hrs opening and closing the butterflies "just staring" .

Yes indeed Sean. That looks fabulous.

Sean,

We've chatted a bit via PM on this one, might as well do it here, for others to benefit.

I am going to follow your example here and go for a EFI conversion next winter. I'll be pulling my engine and will be doing a number of things, from re-coating all frame tubes, replacing all hoses (fuel and coolant), replacing exhaust headers to this EFI conversion.

On spacing of the TB's: I can't quite make up if you only split the Huyabusa setup in the middle, while keeping #1,2 and #3,4 grouped together, or if you had to split them all?

Where did you end up attaching the throttle cable? At the assemly that you've made in the center? Looks like this might be something where I could use the old Weber levers and all, or is there a reason that this will not work there?

Wouldn't a stock carb airbox work with the new setup? Just rivet in a new bottom and cut out a bunch of holes on the new locations? Yours seem to be spaced further apart than the Webers, so I guess I've just answered my own question...

What did you do with the oil filter, and what is that blue anodysed drum that's in place of the filter there?

You seem to have gone through a number of iterations on the fuel feed to fuel rails setup. Are you happy with the way things are now? What made you change things?

Thanks!

very interesting topic...
Just done a change from carbs to ITB with a DTA on a 2 litre Alfa Romeo Nord engine.
165 HP at the wheels.
Took a lot of fiddling on the dyno to get it right, and haven`t run it at the track yet, but on paper (dyno graph) its looking good. Also the torque curve.

 

Stock spacing on the pairs ... just opened up the gap in the middle which gave me room for the throttle linkage.

The carb linkage might fit. I attached the throttle cable in the middle ... same mount point on front cam cover as injected car ... not sure if that's the same on carb cars?

I'm going to mod the connection to the TB's ... should be a lot cleaner and a lot more room for connecting heim joints .. that'll be easy part to make/copy once it's figure out.

Stock oil filter will fit ... I like the blue ones 'cause I can take them apart and look for debris.

That's my latest itteration of the fuel rail which will intefere with the stock diameter oil filter but should be pretty easy to find fittings/change to clear.

Yeah carb air box seems like it'll be pretty close.

I'm close to finishing this up and getting the deck lid on to really see clearance.

cheers

 

What engine management are you using?

What are you using for mapping the fuel delivery .. TPS, MAP, something else?

Thanks for sharing.

cheers

 

compu is a DTA, with Jenvey TB`s. Fot the technical side I have to consult my friend who has done the build-up and so on. Have health issues for some time now on and of. All I have seen so far is the dyno graph (and the bill for the parts etc).
