lol That's what I was going for. Especially after a few upgrades. Actually I've read a dissertation or two now on water injection. The reason it actually "decreases" performance on stock computers at low boost is because it moves the Peak Pressure Point to a later Crank Angle. However, the cooler and denser air makes the ECU think it's under more load which causes it to retard the timing (it needs to advance due to the slower burn) and move the PPP even FURTHER back. If you have an ECU designed for water injection in can increase power and even gas mileage at "all" conditions, however I do not know of any tuning company specifically desinging spark controll systems taking water injection into account because the computer would need to know if the water injection was on or off. However a large advantage can still be had from water injection a stock, or modified turbo car. This advantage is the knock threshold. Water injection SIGNIFICANTLY increases the knock threshold. Allowing far more boost on lower than ideal grades of gas, and in warmer than ideal temps. This significant reduction in knock sensitivity at any temperature is something that no intercooler can boast, and the reduction in temp as a result of the water being injected is only a secondary benefit.
Since it is clear someone has already water injected a T7 Viggen, that will be on the slate for future upgrades on my Viggen. First off being catless downpipe (it's only illegal if you get caught! ) a better intake pipe, MapTun computer, and bigger intercooler.
Oh and I should note, one of of the previous links, there was a 99 Viggen with 77K miles, water injection, intake filter, and downpipe putting 248hp to the wheels. Since that car is rated 5 hp lower than mine (likely with good reason), perhaps in cool weather mine really does have "close" to 252 hp like I was lead to believe by the g-tech. We'll see. It feels much more consistent with these new plugs. I think this engine has far more power than people are led to believe by it's "rated" figures. I can't wait till it's cool enough to dyno it. Needs new tires and brakes before that. Damn TWR rotors that lip after 25K miles. Getting Group9Performance Brembo's if they fit the Viggen. Says "all" 9-3 models. So they'd better make a 12" one for the Viggen!!
Yours Truly,
