Temperatures dropped alot here in england this last week so I'll be able to lean it right out and still make good temps only joking.
I run .21 rr (20% nitro) with Lrp high torque tuned pipe in my rtr buggy shorter gear ratio up against Alpha tuned engine (30%) in truggy from standing start, the .21 rr dust the Alpha engine right after half mark and towards the end. The power delivery is so smooth from bottom to top it does feel a bit slow if I run on the straight on my own but if I go against with other car then you know it is fast. Tuning and engine temperature is stable now run at 2 plus gals compression is very strong. HSN about 2 turn out from flush never exceed 125 deg c.
