I will try and get a pic posted over the weekend...... my digital camera is broken though....so bare with me.

Cheers guys...

I now have some more thinking 2 do...

I want 2 do it right 1st time so i don't have to mess around l8er...

Guess it now comes down 2 costs,
I have time 2 save...
The main thing that was on my mind was whether or not the money 4 the EBC was justified...

Yes and it's quite effective. Boost pressure was actually more stable with just bleeder jets than it was with the turbosmart single stage manual bleed valve. They take longer to set up and you need a basic understanding of what is going on with the system to tune them effectively.

A manual system like this will never be as good as an EBC, like what matty said, but they can still be an effective budget alternative and there is no reason they can't be equally or even more reliable than an electronic equivalent.

In my opinion EBCs are superior to adjustable T pieces as they eliminate boost spiking and different boost levels under different loads (different gears). I ran a Turbosmart gated T piece for about 18 months before switching to an AVC-R three years ago.

My T piece was set up close to the turbo as is recommended but it would still spike slightly on a cold night (particularly in higher gears). There are no such issues with the AVC-R as it holds a constant boost level in all gears at all times.

It really depends on your budget. If things are tight buy a T piece and save for an EBC but be careful not to set the boost too high as you will see some spiking regardless of whether it is set up on a dyno or the road.

I am very happy with my AVC-R bu they are not as user friendly as the Turbosmart E-Boost and E-Boost2. I have heard nothing but good things about the Turbosmart EBC.

Kinda on thread

this is an intresting read

Hey guys thanks 4 the help it

Here is another one you might consider.

World Motorsports

If you are interested in more info, let me know as I have some in stock

I have just installed one on the race car, but I am yet to test it...... If you are interested, let me know and I will work out a special price for you in return for some feedback.

Cheers.

In relation to the Air fuel ratios, it doesn't matter which boost controller you use to make extra boost, your mixtures are completely reliant on the tune in the computer. You can run 12psi on an electronic boost controller or manual bleed valve and the mixtures will be the same. They say the manual bleed valves are no good because they release "metered" air but it's a negligible amount. Don't let that issue sway your decision.

You can build your own manual bleed valve as outlined earlier and you can minimise the amount of air it releases by using a tight restricter as close as possible to the wastegate actuator and have the bleeder jet after that.

My guess is that it would effect the air/fuel ratio a fair bit as it is stuffing a bunch more air into the engine and they definitely don't continually check the air/fuel ratio from the oxygen sensor - so they run open loop.


I think you would have to tune it yourself with an oxygen sensor up the exhaust to guarantee safe air/fuel ratios.

hey Daveman thanks 4 the input,

that's the kinda info i was chasing...
i liked the fact the jaycar unit didn't effect the air fuel ration n that...

is that true?
