25% Nitro in a small block

[Lunar Wolf]

What would happen? I want to get a HPI Nitro Touring car, the kit ones come with Outlaw 18SS engine, will it destroy it? Would the extra nitro make it run cooler?

will run slightly cooler, but wont destroy the engine by any means. you will have to retune the engine however to the new fuel and nitro content if its been ran on another fuel previously (will have to richen the hsn)
