Just thought i'd give a quick update on this.
It managed a new PB today of 12.2 at 119.66mph at york dragway. It took the win in class and is still going strong on the 100,000mile+ stock engine! This was still on road legal tyres and the strip isn't very well prepared compared to some.
We are hoping for an 11 at Pod on the 4th of October, in the meantime will put it on the rollers to see what power it's making. It's by a mile the fastest stock engined car, hoping to take the record for street tyres.
