I have used the old school alky/water injection that used a windshield washer pump with limited success. I have also used the new high tech systems available today. The new systems operate on high pressure with a much more sophisticated controller. They operate or enable at WOT, a preset boost level or if the knock sensor signal is present.

They do work and work well to eliminate pre-ignition, keep your timing from being retarded and reduce the temp of the incoming fuel charge. All this increases the engines performance by keeping it from being reduced to protect that engine.

An engine with power adders can take more advantage of those adders with alky injection. All engines like a colder more dense fuel charge and anything that allows them to run at a higher efficiency. No engine runs at a 100 percent efficiency but every percent better helps. Alky has about 1/2 the calorie content of gas but runs cooler and will not pre-ignite like gas.......... more compression, more dense, more timing, more better . jeff c
