I think VVEL is too tricky in order to produce more power cuz you have to balance the springs and the VVEL control motors, and its not the springs that is the problem its the motor creation hehe, not to mention the outcome would be too small like 8-15 hp on N/A engine. Its only good over like 650 hp and that's some 15+psi of boost that the engine will be able to handle and also that VVEL system as well, other than that it would be useless to our power range thats my opinion
