Hi
I received a Google Alert on this Topic so came to see what its about.
Only 3 things matter on Topspeed runs Power , aerodynamics & gearing forget weight or accleration, remember 100metres gained at the start is only about 1 second when you are travelling at 200mph+.
Doing 200mph in the confines of a 1.7mile straight like Bruntingthorpe is very difficult indeed sounds easy but aint, the difference between a 190 run & passing 200 is enormous. (5% more speed requires at least 15% more Power)
To put it into perspective a Ferrari 360 crawls up to 174mph in that distance & even the mighty AMG Merc with 700/700 only managed a 189.
The world record breaking Ultima managed an impressive 204 & thats shows just how difficult it is.
Gearing must be optimum no point gearing for 200mph if you aint got circa 700bhp it simply wont happen. Optimum gearing means that 200mph must occur around about peak Power or you will be on a Falling Power curve when you require it most.
My own car has done over 30 of these highspeed runs so im beginning to get the hang of it . Can now reach the magic mark within a mile but it takes massive amounts of Power to do that. Lastest Dyno showed 769bhp/644ft-lb & I use 200bhp atw jets of Nitrous pushed at 1500psi so probably around circa 1000bhp, it will run in 2008 .
I hope this helps to put it into perspective & I wish you all a Merry Christmas & leave 2 videos of 200+mph in the rain to show how crazy it can get.
