IMO ive got my bonito and btt which are clubby engines, theyve both had 3 big events on them, plus we race every second friday, and every tuesday night is practice. That being said ive attended 60-70% of the racemeets locally.
The btt is a little down, but the bonito still has a butt load of pinch in it.
My virtus and keep off's all have under 10L, can still rest them at top-dead and they will hang there with no leaking.

All my engines are tuned so i dont have to lean on them to produce the power i want, lucky if i surpass 75% throttle on most tracks, still hitting fastest lap paces wherever i go.

Just my opinion, anyways have fun and enjoy!
