3SGE Beams: velocity stack testing
Another successful night on the dyno
Tonight the name of the game was velocity stack lengths
the car has always run 35mm I.MEC stacks, I snuck around to ashes place as swipped his 70mm and Jamie (the lecturer) had some stock ae111 lying around measuring in around the 100mm mark
So we had a car, a dyno, 3 sets of velocity stacks and our curiosity. Only one thing to do then
first up was a power run with the “Sock” style air filters still on
then another run with them off
there was a small surprise with “no air filter” making less power between 3500 rpm and 5500 but after that pulled some extra numbers to push us into the 120 rwkw area for the first time WOO HOO
next up was the 70MM
seriously… the sound is just amazing!
they have made the dip at 4000rpm a bit worse.. BUT when the power comes on and revs out to 7500 its just awesome!
then slapped on the stockers
These made the dip area very flat and performed well…. untill 6000 rpm where they dramatically choke up the motor
The 70MM are the clear winner increasing torque and top end power
had a drive of the car on the way home…. its starting to scare me and i LIKE IT!!!!
