Volute Shoot-R will eliminate your intercooler's heat soaking problems with precision. It's especially useful when no intercooler is used at all. Very precisely match flow rates to intake air temperature.
This position is best for sustained heavy boost loads as the intercooler picks up heat faster than it can shed it. Although long piping dulls boost response, remote distance spray = more evaporation time = superior HELP:
Advanced controller like FrostByte or Cortex, are best for staging spray events. However, even a basic box like Snow VC-30 or VC-50 can do the job.
Made from rugged/chemically resistant stainless steel plus anodized black aluminum, this lightweight assembly resists heavy methanol concentrations without corroding. AN fittings are the choice of pro builders but are easy for casual builders to work with, too.
Note: Volute spray is most helpful under heavy sustained loads that would overwhelm and overheat an intercooler and not for primary IAT reduction. Spray at light load will simply reduce heat exchange efficiency.
Note2: Spray pattern shrouding can complicate injection through thick walled cast compressor housings. Thus extended tip nozzles should be considered.
