The Formula 27

I have raced a Caterham at Silverstone but crashed quite hard but I enjoyed it. I wanted to have a go at the 0-100mph-0 record and decided to build a car to do it. I didn't actually build all of it. I bought it completed but modified it so much I ended up rebuilding it.

Here are the specifications of this incredible car:
Rebuilt, balanced, gas flowed, lightenned and tuned 3.5 V8 with Weber (Edelbrock) 4Barrel Carb and Edelbrock manifold, producing over 400 bhp per ton.
Hi-Spec Big Disc brake conversions all front and back with Willwood 4 pot caliper, stainlesssteel lines throughout. This alone cost over 2,000. The car stops as good as a F1 racer.
Brand New Quaife ATB LSD (nearly 1,000.00)
Tyres Delta 205 x 50 x 15" Front Yokohama A022R 225 x 50 15" Rear (the closest thing to road legal slicks you can get)
This car is featured in the Formula 27 Owners Club

O-100 in under Eight Seconds - That's Quick. Even for a car
