Weber style fuel injection - Brissy??

[hogster]

Anyone know the name of a business in Brisbane that does the Weber lookalike fuel injection systems, with the trumpets.

Have a mate looking for a phone number and can't find it.

Don't know the Brissy mob, but at 90+ on the dollar.

www.imagineinjection.com are worth a try

I have had them on for a few years. Very happy with the results

Speak to Corey at Katicore Motorsport. I've bought injection rail extrusion from him before and he has some very nice 8TB setups available.

Here's a link to his web page.

He's south of brisbane from memory.

Thanks guys, I think he is specifically interested in the Brisbane business but I will send the link for imagine injection as well.

Thanks again

Hi Hogtser
Haltec make them they used to be $645 each. Injection Perfection used to make up a complete kit for most engines.. You could get both IDA and IDF 44 and 48 mm throttle bodies.

Can you let us know what he selects. I'm interested in the Brisbane Katicore Motorsport set up- price is not bad even if you add $800 for the 8 injectors...

They look tough but what can you expect from them in terms of increased power. If your motor has a cam and head job done what difference would these stacks make over say a larger throttle body? Anyone know

The main advantage of the 8x T/B setup is that you can run a much bigger cam and still maintain drivability. having individual throttles and trumpets means the reversion pulse from one intake doesn't upset the flow in the adjacent intake ports. The bigger the cam, the more overlap and valve lift the bigger that pulse coming out of each intake tract.

The other advantage is that by varying the length of the intake trumpets you have a degree of manifold tuning to match the cam you have chosen. Much like the importance of primary tube length in a set of headers, the length of each intake tract has an impact on how the motor will perform.

A good example of this intake tuning is the Crower trumpet injection setups they used to run on BB Chev powered CAN-AM cars. They ran staggered length trumpets to flatten out the torque curve.

You've probably seen the iconic intake setup that was often replicated on street machines and hot rods in the 70's and 80's.

Plus they look fantastic.

I certainly wish my Cobra had them.

Aussie Mike Mike I was under the thought that there was an air flow problem to the back throtte bodies. The hieghts where diffent sizes to break up the air flow. In the air inlet on a GT-40 there was no problem but in a cobra, there was a flow issue with the back carbs because of no air box. The back cylinder on each side runs leaner than the front 6. I was told this by a weber pro racer. Rick L.

[Aussie Mike]

Air flow wasn't a problem with the Can Am cars with their trumpets out in the breeze. From what I've read it was just for improved torque spread with the Crower mechanical injection setups.

It may be a different situation with webbers installed under a bonnet. Carbs rely on airflow through a venturi to pull the fuel vapour through into the airstream. Restricting that airflow could have a real impact on metering.

These mechanical injection setups run individual jets for each cylinder to trim them and the crank driven fuel pump combined with a valve tied to the throttle linkage to meter the flow of fuel to each cylinder. They are pretty agricultural and just supply X amount of fuel for a particular RPM and throttle position.

if someone gets a hold of katicore let me know i tried several times a couple of months ago and had no luck!!

[sambo]

Errr... excuse my ignorance, but where's the air filter on those things? They do look terrific though.

[boxhead]

No air filters Sambo, not on the Can Am cars anyway.

You can fit the foam sock that would normally be fitted to a weber carbie.

Or you can make a larger air box that mounts over all the intakes.

They are in the process of a reshuffle.

They suggest contacting Austrack Motorsport Sydney, 02 9820 4255 for any inquiries.
