Rampage Speed Density Kit – R35 GTR

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
