NonStopTuning Tri Flow Cams by Colt Cams



NonStopTuning is proud to announce our collaboration with Geoff Bardal and Colt Cams. Hours of testing on the dyno, street, and track has led to the development of the new line of Tri Flow Cams, now proudly offered by NST for the Toyota 4AGE and 4AGZE.

The most common problems generally encountered when traditional performance camshafts are installed are the loss of bottom end torque, poor idle quality, and computer problems. This phenomenon has become more prevalent with high-revving, multi-valve engines. When an engine is optimized for HIGH-RPM power, the LOW-RPM power will unfortunately have to be sacrificed... or will it?

What if someone could make a performance camshaft that could make better power both at HIGH-RPM and LOW-RPM, without the use of a variable lift cam system?

Tri Flow Camshafts manage to do just this for virtually ANY multi-valve engine. By staggering the opening times of the two intake lobes, a swirling effect is created in the system. The principle behind this design is to open the intake valves progressively. Opening one valve first allows the fuel to travel across the chamber at a greater velocity due to the smaller venturi action, it then helps pull in the second charge at a faster rate.

In turn, with the larger cam, the engine has better vacuum at idle since there is less overlap. Throttle response is greatly increased and power delivery is better across the entire power band. Geoff's theories on the "Tri-flow" have been proven time and time again on many different engines. The NST dyno testing has proven the theory, and now it is time to let the 4AG community see and enjoy the results.
