Over the weekend in a local club race, someone with this engine was able to out accelerate an IDM engine! Kudos to OS for producing such an engine at an affordable price!
Btw, how many shims are you guys using for this engine? And what's the LSN and HSN needle setting?

If your running 30% nitro you will need to add one copper shim to the engine or you will get pre detonation.
