Rampage Nissan R35 GTR Speed Density Kit



Speed density is a tuning method of using manifold pressure and intake temperature to calculate the airflow of an engine. The Rampage Fabrication & Design speed density kit is a plug’n’play option to add a TMAP sensor on the charge pipe of your GTR thus relocating the IAT from the MAF and eliminating the need for it.

  • More accurate intake temperature readings
  • Run higher boost levels
  • Run larger mafless turbo inlets
  • Allows use of vent to atmosphere blow off valves
  • Vehicle will still operate if a charge pipe comes off
