I've found that life I needed.. It's HERE!!

This is what you need:
A large ALS valve which replaces the standard idle valve
(So, kiss your idle speed control good bye)
Water Injection (To keep inlet temperatures under control)
A turbo with Mirram shaft (anything else will melt)
Exhaust temperature sensor (highly recommended)
Software for your ecu to control the ALS and the water injection.

Call stu @MSD m8 he will inform you correctly.

Ah, another fan of El Cheapo Tuning.
Be my guest and do it the cheap way and live with the loss of power.
Then watch how your turbo will be destroyed.
Or even worse, how brake lines will melt due to high temperatures.
I hope you have a fire extinguisher.

ALS
Does anybody here fully understand what is happening in an engine when the ALS is active?
Exhaust temperature will reach 900 degrees Celsius and sometimes even 1000 degrees. This is measured a few inches after the turbo. The temperature inside the turbo will be 100 - 200 degrees Celsius higher.
A standard turbo shaft works up to a 1000 degrees, above that it will melt.
Intake air temperatures will reach 50 - 60 degrees Celsius. i.e. a drastic power loss will occur. The only way to prevent this is water injection.
Now I am talking about a real ALS system, as used on Escort Group A and WRC rally cars. I do not mean any system that will make a lot of exhaust noise and that's it. A good ALS system will produce 0.5 - 0.8 bar boost at 1400 rpm with a single large ALS valve. On a WRC with 2 of these large valves you can get 1.0 to 1.5 bar boost at 1400 rpm.
Also realize that when this system is active, you should drive the car differently. The only good way is all or nothing on the throttle. You can't feed the throttle as the ALS stays active for a small throttle opening.
But when you do floor the throttle you will have 4 spinning wheels even with warm slicks on dry tarmac.

Would like to add stu will probebly recomend / use the above anyway so no need for everyone to get there kncickers in a twist
Edit just to add: i have an ALS throttle body that has been machined out to flow more air and also my ALS Valve is just my standard one that has been again Machined to suit
