6 seconds is a very long time when an engine is tuned to its limit, I know your clued up with nitrous but you should apprieciate that the extreme cylinder pressures do great damage if the DUMPING of nitrous is done incorrectly, not to mention the strian on the crank shaft with the heat and weight of the clutch assembly, I have faith in trevors kit hence the reason we are trying it on steve's car which is already a proven car as we have 4 championship wins and a world title with it, ALL with a US kit. I truelly hope trevors kit will be what it takes for us to be the first fully street legal car running on unleaded, street tyres tax and MOT in the 7's.
What motor does jonny run?
