    Well incase you dont know, this saturday gone we had a Divers run top speed challenge at Bruntingthorpe proving ground. This was was over a two mile runway with timing lights,and there was all sorts of supercars from ferrari to Lambos and Porsches. Well even though my 355 could not get to full speed over the two miles of runway, it still acheved 168mph with my big self in the drivers seat. The 360 ran a best at an official 167mph through the timing lights.
    One mile an hour i know, but raing is racing as they say and the deed was done:D :D Some suprised people;)

    Thats interesting, perhaps the 360 buttoned off ? I cant believe that a 355 could be faster.. less aerodynamic, less power, more weight ? Doesnt make sense!

    No the cars had a good few runs and the best time was taken. I have beat 360s before.A race is a race no excuses after the fact;) There was no backing of it was the best time of all its runs. Every one was going for it, they all knew what they were there for.
    You dont have to be a skilled driver to push the pedal to the metal in a straight line. Although the 360 did go faster than another 355 by 6 seconds, but not faster than mine:) Also the 360CS was 4mph faster than me at 172mph, and he was also going for it. So how much faster than me should the standrd 360 have been? With the speeds of each car that i have given why would you just not beleve that my 355 is just quick? You know i gave a ride to a bigger guy who was 23 stone and i still recorded a speed of around 165mph.To see the official results go to the UK section and see them all including the two fastest which were both over 20 years old, and recording above 190mph!

    I am surprised you did not go faster ??

    The only "trick" to it is to make sure you are redlined in 5th before shifting to 6th. If you shift a little early you will stop accelerating. I am not saying you did this or the 360, but it is something to consider. This is common to see because the engine is really screaming above 8000 and many casual drivers are not comfortable keeping it there

    You have made some very logical points there, and yes i was red lining every shift. When ya against Porsche GT4 and GT2s ect ya got to give it 100% win or loose or ts not worth ya being there. Its no wonder that Porsche drivers think ferrari drivers are a bunch of nancey boys who are to sacared to use there cars when it counts instead of cleaning it:).
    Although i have to disagree with your opening line "i am suprised you did not go faster", becourse even though i was not bouncing of the rev counter, had i gone much faster then i would have been in CS terortory. And think about all the upset that would have caused:( Although i have regulary seen just over 180mph on longer straights.
    And as i said before its not the first time i have beaten 360 from a start, and i know what they can do very well becourse i drive one very reguarly.

    And another logical way to think about it is that the 360 is not that much more powerfull than a 355 anyway. Whats a 360 just less than 400bhp? My car is the more powerfull 1995 5.2 Motronic (as opposed to the late 2.7) with De-cat capristo with K&Ns, which will mean that its in the area of 390bhp plus, and thats if you beleve that a De-cat Capristo with K&Ns only add a minimum of 5 bhp, it could be more.
    So there is no denying that with two equil drivers on a twisty track that the 360 may be faster around it, but in a straight two mile runway a few horse power more does not make much difference in the real world, well the results stand:D
    But likei said Rafo at least your giving a logical responce as opposed to giving responces based on what you heard or read about, or the usual 360 drivers exscuses of must have been bad driving;)

    So do you know if the 360 was pure stock or slightly improved too?

    Down the 1/4 mile Ive seen 360's running 12.4's as opposed to a 355's 12.9s...

    Not that I like running f-cars down the strip :p

    Interesting results though!

    Besides the shift points you also have to consider the launch. Getting off the line fast without wheel spin and with max power takes some skill. Don't discount the fact that you may be better at this than some of the other drivers.

    I don't know what the drag coefficient is of the two cars, but my impression is that the 355 is a smaller frontal area car so the car is displacing less air even if it is less slippery. Plus the tire width advnatage of a 360 for cornering is a detriment in straight line running (more rolling resistance). I remember the old Road and Track with the yellow bird Ruf Porsche that topped out over 200 mph surprised many but the explanation was the same (less tire width and less body width helps top speed).

    If you had the 355 engine in a 348 body, you could have gone a lot faster. Those side slats are worth at least an extra 10 mph.

    :D

    With the little experience I have in Standing mile " racing " I have found that even exterior rear view mirrors being removed will gain you a few mph on the top end, as will Tire PSI, and taping intake and brake ducts...

    When I rode the motorcycle in the 200mph class, I would remove mirrors, turn signals, lisc plates, etc.. all made a difference in top speed.

    Another thing to consider is how you launch, as in 1/4 mile racing, it makes a difference.. How were you launching? Any traction problems?

    Your quite right about the mirrors, i used to do that on my bikes at the strip. As far as of the line goes, some were good take offs some were wheel spins.

    I am running wider tyres than the 360s anyway. And the yellow bird that won on saturday also suprised many:)

    It was realy not about taking of at the line though i did gun it. You see when you took of you drove about 1/4 of a mile before a long fast right corner to help build up speed then once the corner is over then there is a two mile straight to the timing lights. I could have slowly rolled of the line as many did and still had the speed read out that i did.

    As i said mate if you go to the UK section all official times have been posted. And you will also see that the next car up from me was a 456 at 2mph faster. And that car was also driven well.

    It sounds like you had a rolling start. If thats true, and neither car was able to reach top speed, isn't the speed at the starting line a factor? From your description, exit speed off the corner would determine your speed at the starting line. I'm confused as to how this race was run.

    Well we all had the same start line, and some cars did not gun it of he line and that was there choice., so if you wanted a roling start that was up to you, and if you wanted to drop the hammer you could. Take te 575 he just rolled of the line and still thrashed me once he got to the long straight. It was a top speed of your car run, which means that the aim is that within the start and finnish line you go as fast as you can to cross the timing light at the end. There is no confusion.
    And the 355 or the 360 could not reach there top speed in such a short 2 mile straight, not even the f430, dam not anycar there on the day.
    MB You had as many runs as you liked, so yo cold find the right combo to get the quickest from your machine.

    The Cd for the 360 is listed as 0.335, while the Cd for the 355 is listed as 0.35. The frontal area for the 360 (based on published WxH dimensions) is 24.81 sqft and the 355 is 23.95 sqft. So the 360 has 0.86 sqft more frontal area. However, the Cd improvement of the 360 causes the result to be almost a wash.

    Here's an interesting analysis of drag for a 355, estimating impact on top speed of headlights up vs headlights down. They conclude that the extra sq ft due to open headlights or so causes a 10-11 mph hit to top speed.

    http://www.virtualv8.com/f355.htm

    P.S. In addition to the extra friction caused by wider tires, any increases in downforce in the 360 vs 355 should also be a factor.

    I agree it had to be the driver unless the 355 was not stock. My father and I go for cruises all the time in his 360 and my 355 and his 360 blows me away everytime.
