Sons: AE Big Bores

Mine: Tekin 13.5 motor
Sons: Tekin 8.5 motor

Craziest thing...I put about 3 packs through each one yesterday (spent about 6 hours at the track yesterday just messing around) and on average I was consistently .5-.75 seconds a lap faster with my 13.5 vs my sons 8.5!!

I never would have guessed that the 13.5 would have been so much faster and easier to drive consistently, in a 4mod buggy!! The 8.5 is entirely too much power, so much so that it's hard to drive it smooth! Although there was a few times where the 13.5 didnt give me the grunt that I needed when I got off my line...so thinking a 10.5 or 11.5 might be the perfect motor for our track.

Just thought I would share lol.
