Yes its a road car will only do one more Topspeed run. The 9180 will spool about 1000rpm earlier than the GT42 ( we have seen that recently on tests) & make maybe 60 more horses so it will be a major step forward as a road car. For the last Topspeed run all that goes out the window its purely about Power nothing else. How fast the car goes will depend on how much Power Mark will let me risk. We should have circa 1000bhp on the GT42 & a similar amount with the 9180 with a shot of gas. IMO we will not risk more than 900bhp for 1.7 miles so its up to Mark what combo is used.
Our last completed Topspeed run was back in November 2005 & its strange that this car is still seen as a Topspeed car it never was. Its one of four road car in the family & at that time in 2005 I still drove it to work.
