I can't say much about the Tessman Spec 11 but I run the OS spec 11 (gold head) in my truck and it is awesome. I much prefer the spec 11 over the spec 111. However in my Buggy I'm running the low profile B2102 for club meets and the Tessman B2101 Low profile for bigger meets and interstate meets. Safe to say I love the 2102 and 2101 over the Spec11 in my buggy. I'll definitely keep my spec11 as truck motors
