What's wrong with the stock radiator?

You are going to need some thermal mass in order to store the heat the engine produces ... I'm thinking the required thermal mass would likely outweigh the radiator. Water stores a lot more heat per unit of mass than aluminum does.

How much time between runs - how are you going to cool it off between runs? How are you getting back to the paddock?

edit: Rough calculation - if the cooling load is 100 kW for 10 seconds (cooling load is same-order-of-magnitude as the engine's power output) and there is 3 litres of water in the system, it'll raise the temperature by about 80 C. If the engine is already somewhere near operating temperature to begin with (say 60 C) you're well beyond boiling temperature at the end. Obviously the metal and the oil add some heat capacity, so it won't be *quite* this bad, but it's still not good. I'd rather try to keep the engine temperature somewhere near consistent ...


Helibars, MRA screen, Ohlins damper, reversed shift pattern, sorted suspension, braided lines, Michelin Pilot Power, all else stock 'coz it's fast enough!

Lots of grudge bikes out there that are dry blocked...but most of them push the bike to the line and get towed back from the top end. If you don't plan on doing that then I would find a radiator to put on. Even if there is some damage on the bottom, have it cut to remove the bottom section and you'll be good to go for a drag only bike.
