Power Benifits of water injection

[macka'sxr6t]

Hi all,

Good to see the forum back up and running. i just joined before the upgrade.

I'm extremely interested in this subject. This is my first turbo car and it's awesome. I'm from Australia andyou are probably not familar with my vehicle so I'll give you a quick run down. I'ts called a Ford XR6Turbo, engine specs are

4.0lt turbocharged 6 cylinder
24 valve DOHC VCT
Max torque = 470nm from 2000 - 4800 rpm
Max Power = 240 Kw
@ 6 psi boost
14.4 sec 1/4 mile

I have done some mods to mine and have increased the power to
300 Kw by increasing boost to 9 psi. I will be increasing the power to 360 Kw in 2 days by adding larger injectors and increasing boost to 12 psi. Cars running these mods are doing 12.3 sec 1/4 mile using street tyres.

My question is do you think that water injection would provide any power increases or other advantages to help improve the performance of the engine. I would like to be one of the first cars in Australia to run in the 11 sec bracket on street tyres

My ecu can control the water injection what would be the best system to use and why.

Looking forward to your replies
