I've been thinking about running high boost and water. Anyone know the =
relationship between boost, octane, and compression? Say I was running =
8.5-1 with 93-94 octane pump gas, with water injection how much boost =
would be possible?
Anybody running a street car that can help me out with selecting =
baseline water jets and boost levels?
There are no writtin in stone rules on WI.
Some things I have noticed are.
You want a min of 200 PSI (250 even better) for the operating pressure =
to truely turn the water into a fine mist.
It must be about instant on.
System must be able to supply as much as half as much water as fuel for =
a serious effort.
The amount of boost you run will effect the actual discharge amount of =
water.
Some applications need it starting at 2 PSI, and others don't need it =
till commanded (Stagged at max boost, in one application 60 @ PSI boost)
It's a matter of tuning, for your particular application. =20
