Bruntingthorpe 2 mile runway max speed run.
Discussion
Meant to post this yesterday , apologies it went on other boards first.
Dear all,
You may have read about previous max speed runs & fun had on the 2 mile straight.
A few of us at work have booked Bruntingthorpe to go again and have some fun.
It is looking like we may have limited space available if any of you are interested in coming along.
The day is Sunday April 27th and will be from around 11am to around 4.30 pm, will probably involve around 6 maximum speed runs, these will be electronically recorded and also then displayed on electronic boards around 100m after the speed traps.
We currently have varying cars going from TVRs, Porsches, Ferrari's to a replica Cobra and a few other interesting cars.
The 2 mile straight is very wide and smooth & we will only be running 2 cars on the runway at any one time.
If you are interested please drop me an email, it should be good!

I'm booked down to go.
I turned up at the last Brunters run (late) in a friends Skyline GTR and very embarrassingly we didn't even complete one run and had a thoroughly enjoyable 4 hour trip back home on an AA Transporter......
After seeing so many lovely 911s at that event it re-kindled my love for the old German autobahn-muncher, so I bought a 993 RS 3.8 last week. Amazing road-feel, sound and fun......
I might bring this along (I know it won't break), or I might bring along one of my Skyline GTRs, which are much, much faster (but more fragile).

Guy, you may be only dimly aware of how much the Skyline saga meant to the P-car people at Bruntingthorpe. Absolutely instant justification for ALL (and I mean ALL) the money lavished on the cherished 911/944/968/964/993/996/TT/X50/RS whatever.
I hope your RS is better behaved!! Cheers, Maurice.

Maurice,
I did guess that, hence why we left so quickly.
I've always known that Porsche are simply the best built sports cars (had a 964 a while ago), however I do still have a thing for the Skylines.
My R34 GTR went to Germany and back last year for the 24 Hr Race at the Nurburgring and we did 200mph on the autobahn with three 6 foot adults and a bootfull of bags, no problem, something no 911 could do. My R32 is also one of the few chances anyone on the planet gets to drive a 1000bhp car on the road (it dynoed 831bhp at the axles recently even with a misfire).
That said, it was a fantastic pleasure to get back into a 911 again and hear the wonderful aircooled roar. It was also a pleasure to drive a non-turbo car again, made me remember what instant throttle response is. The brakes on the RS are simply amazing and are what has impressed the passengers most so far.

I'm in, want to try a couple of standing starts this time (is JezzaC going). sorting 6th gear, but wont be done in time
Paul
Excellent news Paul. I have been told Jeremy will be attending by a third party, I've also been told a certain previous attendee will be wheeling his Ultima out rather than his BMW breadvan with only 3/4 throttle. I presume you're going with the shorter sixth gear as you and Alex were discussing last time.

PS - interesting threads going on in the Cerbera and the Tamora/T350 forums. Some people believe decent sorted TVRs are quicker than Porker Turbos.
X Interesting. As far as I know given more or less eqaulity between cars the one with the higher power to weitgh ratio should pull fastest, right ?
I know there will be some other factors, eg gearing, but more or less it boils down to force=mass x acceleration, no ?
So 450 bhp option on a 911 tt at around 1400 kgs = 321 bhp per tonne
versus
400 bhp (claimed on a post for a standard tamora with 'power' option) at about 1000 kgs = 400 per tonne.
The tamora should have it (assuming it didn't break down)
Any one know for sure the power/weight figures ?

No, AFAIK, it's mainly a question of TORQUE overcoming DRAG.
You will probably find that a 996 Turbo has spent half its life in a wind tunnel, whilst a Tamora diecast model (with wool attached) has spent three minutes in front of Peter Wheeler's wife's hair dryer...
Check the torque... once mass is moving, the weight becomes less important IIRC.
I bet a 996TT would dump on a Tamora in every measurement or increment.

More factors than that, but in my experience the influencing factors vary through speed:
0-30mph - Traction and bhp/ton are biggest factors
30mph - say 100mph bhp/ton is most important
100mph - 160mph+ - bhp and aerodynamic drag
160 mph+ bhp, but aero is now much more important
As the car accelerates faster, progressively more of the power if being used to overcome aerodynamic drag rather than accelerate mass, so the weight of the car becomes progresssively less important at higher speeds, though the relationship is a complex multi-variate algorithm.
Top Speed has very little relationship with mass......
Back to Tamora vs 996TT, the TT will win at every point in the curve based on data I've seen. Remember peak bhp is just one figure, it's area under the torque curve that matters for acceleration and a TT has tons of torque whereas a Tamora doesn't.

993ttS = 450bhp@1540kg = 292bhp/tonne, in theory the Tamora should spank the porker. Based on these figures I'll keep quiet rather than getting egg on face

P.S. I'd still have a tenner on Darren!
It is intersting if you look back over the recent Bruntingthorpe excursion.
The Turbos cars had it on the day by some margin,however if you consider we had a very well driven TVR Cerbara 4.5 litre which I beleive are 380 bhp in standard trim weighing around 1100kg.This car achieved 159mph as a best speed on the day.
I was astounded to see a regular 3.6 C2 with 316bhp coming in at 1360kg achieving 158mph.The Carrera was driven by a pleasant chap who from what I understand had little trackday experience.
Now this is one of Blackpools more brutal cars in line with a cooking C2!!! it goes to show drag,position of weight,gearing,torque and no doubt many other factors make a contribution to how a car actually performs in the real world.
Clearly you cannot go by the stats in the back of car magazines for true comparisons.
