My Triumph Speed Triple project update

[al lkosmal]

juice,
That was always my plan and I had many people request pricing for the kit, but no buyers. It became clear to me that, although priced far below the price you would pay for any alternative, complete ITB arrangement( with ECU)..........what I thought was a fair market price for a complete kit, was too high for the market. The market has spoken. If you PM me your email address, I'd be glad to provide you with pricing......and then you can decide and let me know what you think..

Been trying to find out what injectors you used in this application.... Couldn't get my eyes on any info about it..

Trying to find out some info about it all over the interweb now too as the TB's I bought. (Same as these) comes without injectors and I would like to know what to look for that would be suitable for the 2,0L engine of mine...

Hebster....follow the link above to the Megasquirt site. On the left hand side of the page, you will find the link to the MegaManual. Click on the Injectors & Fuel supply section and scroll down to the injector calculator. Lots of good info here.

PS: I used the injectors that came with the Speed Triple ITBs. They were rated at 26 lbs/hr (270 cc/min) at 43.5 psi. I sent these to WitchHunter to have them cleaned and tested. That flow rate will support a 6 cylinder engine at approx. 250 HP .

The standard triumph injectors work very well on my 2.2 T.

[Hebster52]

Thanks!
Appearantly 200cc/min would be enough for my engine when aiming at 150-200hp?

[Joeaksa]

Very interesting thread and great work!

[al lkosmal]

Herbster................you got it...........19 lbs/hr (199.5 cc/min) is a common injector size.

Joeaska....thanks.

Here comes a bunch of new questions....

What thickness are your adapterplates?

Did your respace the TB's so they are the same as the manifold intakeholes?
I guess your Weber manifolds are the same as my Zenith manifolds? If so the TB's need to be moved about 6mm from eachother to line up with the manifold holes.

Did you keep the exit (lower end) of the TB's original oval or did you reshape them to more flow with the round manifold holes? Looks oval in the first page.

I will probably come up with more questions when my project evolves..

hebster,

1. My adaptor plates are .50' thk (12.7mm).
2. My TB's are spaced to match the weber manifolds spacing. (same as Zeniths)
3. TB's are moved to line up with the manifold spacing
4. My spacers are machined oval on the top, to match the TB's port and 40mm round on the bottom to match the weber port....the transition in the spacer is very smooth and nice.
Note: I thought that the metal around the TB port was not thick enough to be able to open up to 40mm round and still provide enough strength.....I tried it.

Trying to figure out how you did the idle control
Did you use the Triumph original idle valve (or-what-ever-it's-called)?

If I figured it out correct the idle control is connected to each TB at the tubes on the inside in your sets?

[al lkosmal]

I did use the Triumph Idle air valve. This valve is controlled by a stepper motor. Megasquirt has the capability of controlling this stepper motor, based on engine temp input. If I remember correctly, their are a few standard choices for Idle air control. I chose the Bosch default and it worked perfectly.

Currently stuck in Las Vegas.....tying to get back to Seattle...the weather is not cooperating.

Bob,
Very similar with the exception of the Weber manifold to Speed triple adapter, which I redesigned.......

I got distracted by something shiny


.......... and I've opted to use Weber linkage instead of the cable linkage. There are other subtler changes, as well, but I'm just improving it as I go.

I've also built a 3.6 with 46mm TWM T'bodies and next I'm building a hi-butterfly like system using MFI and EFI bits.............I like it.

[clutch-monkey]

will be interested in the 3.6 application soon, i think..

Greetings,
No dyno yet. My buddy Tony (Wolverine) is back on track with his project and mentioned getting a dyno done, so we shall see. Sorry about the delay in responding. I will be away from the office until Wednesday. You have been emailed and pm'd. Keep up the good work, I appreciate it.

regards,

Al
