A link to the website is: http://volvo-t5.co.uk/phpbb/viewtopic.php?t=1546
If you can't access the page, here is a copy of the text:
"it is absolutely not worth it for the follwing reason -
volvo designed the inlet manifolds so the air flows into them then up and around into the engine. with this design , as the air flow goes up and around, the water vapour will drop out of the airstream as it is heavier. and as a result you loose any benefits from the water injection such as preventing pinking , and all the water would gather at the bottom of the inlet manifold
a better solution is to use an intercooler spray preferably co2 or n2o as they are much colder than the water anyway. these intercooler kits are available from ?180 +vat so are much cheaper than aquamist.. the only downside being you've got to get gas refills and water is readily available .
dont get me wrong though guys i'm not saying water injection doesnt work , it's just that for the reasons i have stated above it is not suitable for our volvo's . new mini's apparently have the same problem" |
I have seen this email before, cannot quite make out the what the guy was trying to say. Water in all forms, large droplet, mist, vapour, etc will all go into the engine during boost conditions - 5-10Kg of air travelling at almost supersonic speed will not allow anything to stay around very long including a big bolt (don't try that).
Sorry it just doesn't make sense. Here is a Volvo we sponsored and doing very well with an Aquamist 2d. It was racing in the European Endurance Racing Series Competition this year.
The car's ECU was tuned in Sweden by a Volvo Engineer.
