I am trying to figure out how to get the Honda TPS to work. I figured I'd just do it like jeff did as I am using the same TB's as him, except, I'm not sure how to safely connect the Honda spindle to the Gsxr spindle. I have a few old honda TB's to use. Anybody know of a writeup anywhere that includes that part? I just really would rather not JB weld it or anything like that.

I've searched hard for this, but all I have found was one set of really horrible pictures and a couple of really bad explinations, anybody who has done this before, could you walk me through it?

thanx in advance.

 

check this out dud... http://www.homemadeturbo.com/t....html

good luck... let us know how it went...

 

hehe, I am originally from homemadeturbo, jeff's pictures don't really show the actuall connection between the gsxr spindle and the honda one, only that they had been connected, you know?

 

I need to connect this....



to this.....



how do i go about that? besides the obvious "jb weld it on there"


and here is a pic of my kitten, just for fun....

 

train the kitten so that you will only feed it when it turns the TPS

 

LOL

 

whats the advantage of have ITB?

 

I would use those flanges if they had injector bungs in the stock locations, there is no way I'm using the GSXR injector location. Honda put my injectors where they did for a reason.

 

LOL... and that reason is drivability and simplicity. Performance wise the further away the better atomization. I personally use the stock honda location as well, nice and simple plus it allows me to use the expensive rail and lines i've already purchased.lol

 

hehehe sorry mah bad...that i didnt quite get as well...sorry dud....

keep us updated with the itb's aightz...

 

NP, I'll update w/ any progress.

yes honda also gave you a manifold not itbs. look at toda and twm itb kits their injectors are right in the middle for best performance and fuel mixture. but hey keep smoking that weed if you think that

 

back on topic...

does anyone know how most people connect the Honda spindle to the gsxr one?

BTW, that is a really good way to sell product.

 

use the GSXR injecors.... the 1000's flow 245cc/min

youre so cool wow. i did it to prove a point. i could care less if he buys one. my products are selling just fine. one less anoying 17 year old ricer moron that only makes stupid comments.

 

^^^ way to generalize (I'm 21, first of all. second, you have no grounds whatsoever for calling me a ricer) and jack my thread. I asked a serious question and I was looking for a little help.

Good luck selling your product, and by no way was I bashing it. However I'm not sure why you posted it in my thread as it had no bearing on the topic at hand.

anybody that has done this setup before, please help me out, thanks in advance

 

You actually might wanna take his advice with the injector placement farther away. You say theres a reason honda put them there, well yea, it works for many people whether stock or in race form. But theres also reason why Jenvy, Twm, and Toda put their's where they do also. Think about atomization.

 

Ugh, its not that cut and dry people.

To answer his question first...

I beleave the method most people use is simply shaving the honda spindle so that it fits in the GSXR TPS hole. (Which is T shaped). With slight clamping force it should hold and turn it just fine.

On injector placement,
There is a LOT of turbulence behind a butterfly valve. So placing the injector right after it shoots the fuel straight into turbulent air. If you have enough space between the valve and the intake valve the air does have time to automize better. If you don't, you have fuel that has automized worse.

Further, you run into a problem with vacuum lines. Since you have to plum the lines PAST the injectors, all your vacuum sources are going to get filled with gas. Scary thought.

interesting thought, but arent you pulling air from the vaccum lines/canister into the engine to create that vaccum, so how would they pull the fuel into them? Am I not seeing something here?

thanks man

 

You are getting vacuum by tapping the IM, when the piston travels downward (intake stroke) it creates a strong vacuum sucking air in from the manifold. Since fuel is now going to be traveling down past where you are tapping (since the injectors are right after the throttle plate) there is now fuel traveling in the area you are getting vacuum from.

Look at all the stock vacuum areas.

The back of the plenum (brake booster), the front of the plenum (PCV) and the front side of the plenum (fuel pressure). Where are the injectors? Right in front of the intake valves, very little chance of enough reversion to send fuel into the vacuum lines.

Nothing of this nature is that cut and dry, thats understood. I was simply trying to put out that just cuz Honda put something some where does not mean its always the best place under ALL conditions. I simply mean to research and explore different options.

But about the fuel, I know plenty of people running such set ups with the vac sources closer to the head than the injectors are, with no problems. For what its worth, On my TWM/Mikuni carb set up I run, my booster ports are upstream of where the fuel is added into the mixture, I have no such problems.

If you look on the TWM ITB's, on the underside there are nodules where you can install vac nipples. These are close to the head, with the injectors farther back. I've seen pics from a motor CHEETAH (greg) had, and when speaking with him on ITB's he mentioned no such problems.

 

Its good to hear first hand experiance, and in this case problem-less experiences

I still have to wonder if its more that no one noticed an issue rather than there is no issue.

I can't imagine that somehow there isn't fuel running through the vacuum lines. Over time it has to pool, as its got no where to evaporate too?

Maybe there is a method of filtering out the fuel that I can't think of? (maybe hooking the evap canister up to it? something like a catch can?) but it still would worry me that now all my vacuum related items are now extremely flammable if nothing else

 

The cylinder is whats creating the vacuum bro. Think about it. The fuel simply goes where the vacuum is drawing it into, which is the cylinder, especially in straight runner system's like sidedrafts and ITB set ups. Even if theres a vac line more up stream, the vacuum in that vacuum line is pulling towards the cylinder as well.

 

Actually I think your right, I have been thinking about it all wrong.

Its sucking from the lines, not into the lines.

edit: on further thinking, while you are right it should be sucking towards the manifold and not out of the manifold... at some point at WOT vacuum is going to be really low and it can even hit 0psi (this is easy to see if you have a vacuum gauge). While there may not be as much fuel pooling or traveling as I once thought, I still think there is some risk of fuel entering the vacuum lines.

 

he's right, unless you are running boost into them (which BTW I am shhh) in which case there is a good chance you'll get fuel in boost lines. I am going to run the factory injector locations, and I am welding tubes to the gsxr injector bungs which in turn will be welded to a vaccuum canister. It will work better <U>for me</U> this way, I'm sure N/A it wouldn't. BTW the reason I posted this in all motor is because I figured you guys would know a whole lot more about this then anyone else. I'm going to run them NA for a couple days while I'm making my plenum anyway, so technically I'll be all motor ITB's for a little bit.

thanx for your help guys, I'll post pics when I'm done.
