V1 is s-trim (louder) v2 is sq trim (quieter)
Id take h/c/i over a s/c any day of the week. H/C/I is 10x as fun on the street, the difference is beyond night and day. You feel the difference more than you would bolting up a supercharger to the stock motor, because you move your powerband up, the car no longer hits that "wall" after 4800rpms, it sounds 1000x better, and theres nothing more fun than sitting at a light loping away. Theres nothing more satisfying than the first start up and you hear the car which you are so used to hearing, sounding so much different. Its not only the lope, the car is much louder and SCREAMS up top, for example, stock with 4.10s, you nail the gas, the tires are spinning then they catch up top. after h/c/i, you mash the gas at 2k rpms, the tires stick, hit 4500rpms and they start spinning, lol its so much fun, makes me smile just thinking about it. I dont regret anything at all about a h/c/i swap. And as far as streetability, if a TFS stage 1 cam isnt streetable, I dont know what is.
btw yes, I have the TFS top end kit.
