Newbie with a supercharged monaro

[leedpm]

hi all,
I?m running a 04 monaro vxr with an intercooled Magnacharger 9psi 2 bar mafless tune with 440rwhp.
As I?m a newbie to water injection I no that the engine will benefit from it once it has had a custom tune, but can anyone tell me a rough guide to the gains it will achieve, and is it really worth it.

Cheers.

9psi 2bar? Not sure what you mean by that, there's about 14psi to one bar...

Anyway, basically, if you have a setup where the air inlet pipe is getting hot then you will benifit from cooling but otherwise it will mainly be the extra fuel that will give you more power. I see and increase of 20bhp from 195bhp to 215bhp on a 1.9 diesel Vectra. I don't know if you'll see the same sort of percentage rise but you should see enough gain to make a difference.

Personally, I think you are being greedy and you should give me some of your ponies!
