Pretty interesting theory has anyone here given this a try? Wonder how it can be incorporated into a 5 valve head.
Made 98 whp more with 5psi less boost on Mitsubishi 4g63t

Yes.... thought about it... back when the Triflow cams were available, I did a little research into using one O/S intake valve...... for me... thats when it ended because no one wantwd to pay for the experiment

Btw... TVIS is a method to introduce swirl as it partially blocks one intake valve of the pair

True. Just wanted to see if anyone has tested it for themselves amd compared.
