IMO the standard Torker isn't worth a hoot until you get the rpm's way up. I had one on a 360 and switched it to a RPM air-gap and it made way more power throughout it's rpm range, which it peaked at 5800. The Torker 2 seems to be much better. A buddy of mine had a air-gap on his 340 and put a Torker 2 on it and surprisingly it took off just as hard and definitely pulled harder after 4500 all the way to 6000 where he shifted
