What is fastest Nitro or Electric?

[Gustav]

I like to consider it in terms of power to weight ratio,with BL/lipo having the edge over nitro.If you take the weight of the Nitro(engine,engine mounts,pipe,tank,RX pack,clutch assembly,servo)then BL/Lipo (packs,esc motor,motor mount) can come in under that weight with power to spare.A BL/NiMH can't beat nitro for power:weight but has an abundance of instant torque that usually see off Nitro in a straight line.I think the power delivery of nitro has it's advantages too.
