As my confidence grows, the 300 or so horses at the rear wheels definitely deliver. If I plant my foot the secondaries open, the cam kicks in, and she’s off. Actually, this is without question the fastest Cleveland powered car I have ever driven, and that's before the NOS is activated.

Now this is a new engine so I'm only going to try this once to see what happens. In reality the engine needs to be run in for a few hundred, if not thousand, miles before I unleash 250 extra horses in an instant. However, here goes...

Finding a nice piece of straight road across Salisbury Plain is not difficult. Dodging the odd tank, however, can be. With no military hardware in sight I drop a cog and flick the NOS switch on the dash. This means all safeties are off and all systems are ready for launch, Huston.

With the engine at a steady 2500 rpm I plant the throttle deep into the Wilton carpet activating the nitrous micro switch. Whoosh..! The rear wheels scrabble for grip and I’m literally slammed into the back of the seat. Fighting for control I manage to keep the Tojeiro pointing forward even though the rear feels like it's on ice. Glancing at the rev counter I decide to halt the burn. 6000 rpm is more than enough for today, thank you.

To be honest everything happened so fast it's hard to explain what happened. I'm proud to say, however, on a quiet B road in Wiltshire there is a 50 foot long number 11, and I'm responsible....
