Are Spyders Becoming Extinct At OPCs!

The laws of physics dictate that all mass will contribute to inertia, but how much. Just grabbed some info off the 'net Looking at the affect of 10Kg of fuel on a formula 1 car, you'd have to be going some on the road to eek out the benefit of 10Kg. Yes, 50 to 80Kg, the weight of a passenger will make a noticeable difference, that is undisputed. Yes it all adds up. E.g. a Cayman R is already 25kg heavier than a Spyder, so if you load one up, make the difference say 35kg compared to a stripped Spyder, you may be able to split them in a drag race. If I was to have the car solely for track, yes i'd strip every ounce of unnecessary weight, down to carpets etc. and get the stopwatch out to measure it as I wouldn't feel it, but the car would have to have some serious set up to make 10kg count for some time in a 320hp road car (an F1 car will gain about 0.3s over a 5Km lap, per 10Kg of fuel). But the bottom of page 3 of the owner's manual forbids the use of racing tyres because the high cornering speeds can starve the engine of oil supply. So, how to transfer a 10kg weight saving to the road in terms of performance, in a car like ours (which doesn't have F1 power, torque, chassis or aero), well, you might as well put the stopwatch away and enjoy your PCM if you need it whilst you navigate some fine Welsh roads
I'm sure you're all bored now, so i'll vow to leave the topic alone A Formula 1 car uses between 1.7-1.9kg of fuel per lap of Monaco depending on the car, and each kilo of fuel slows it down by about 0.025 seconds. Nurburgring – 5.148km kilometres. Race distance – 60 laps = 308.623 kilometres. 15 corners in total. A cut down version of a classic circuit. Offers a mixture of corners without having any particularly striking feature. Only used on alternate years. Aerodynamic setup – High downforce. Top speed 313km/h (with Drag Reduction System active on rear wing) – 303km/h without. Full throttle – 64% of the lap (medium). Total fuel needed for race distance – 150 kilos (average/high). Fuel consumption – 2.5kg per lap (high) Time spent braking: 18% of lap. Brake wear- Average. Fuel effect (cost in lap time per 10kg of fuel carried): 0.35 seconds (high) Sepang International Circuit; 5.54 kilometres. Race distance: 56 laps = 310 kilometres, 15 corners in total, a mixture of slow, medium and fast Aerodynamic setup – Medium/high downforce. Top speed 312km/h (with Drag Reduction System on rear wing) – 300km/h without. Full throttle – 70% of the lap. Total fuel needed for race distance: 153 kilos. Time spent braking: 15% of the lap. 8 braking zones. Brake wear: Medium. Fuel effect (cost in lap time per 10kg of fuel carried): 0.36 seconds (average/high) Boxster Spyder was marketed as a road car

A great post which correctly identifies why there are so many different types of buyer/user who have different demands. For example full leather wouldn't be a deal breaker for me, but lack of bucket seats would. However I fully appreciate, understand and respect those whose tasts, needs and opinions differ to mine. And I wouldn't dream of belittling someone elses perfectly valid choices just to try to justify my own. These are all great cars - it is a huge pleasure to own one. even a "bus" example. The biggest problem is what to replace it with (if anything!).ORIGINAL: daro911I was completely fooled by some of the hype until I went to PEC for a Spyder day and drove both a very fat boy not even on Spyder wheels and a copy of Mr D's car but with the extra weight of a radio and metallic paint[
It's a very good question (and a good next topic[
] ) If I was looking for another 2 seater in a similar price bracket that would be a tough call and every couple of years when you consider whether to upgrade or stick, I would probably end up sticking with the Spyder every time. Although, this is what i'd put it up against each couple of years... http://www.carmagazine.co.uk/Video/Search-Results/Video/Video-Alfa-Romeo-4C-thrashed-by-Giancarlo-Fisichella/ The Spyderman who enlightened me about this video may not want to be associated with the marque[] What cars do others think they'll consider when they think about replacing their Spyder? (A 981 Spyder does not exist, but only if you mean you'd keep your 987 forever if a 981 Spyder isn't produced, then it's an acceptable answer[] )
OK lets look at the new 4C it only has 237BHp but now look at the weight sub 900kgs it does the 62 mph sprint faster than a Spyder. says all you need to know about weight savingORIGINAL: flat6It's a very good question (and a good next topic[
Colin Chapman said all this back in the 1960's and stuck with it until he met an American in the 1980's and look what a dog they managed to cobble together CC should never have deserted his core concept of staying light at all costs Alfa 4C is a tiny car and I am sure if Porsche made a jnr league mini sized 2 seater they would have a serious problem making it slower than the bigger guys in the family to keep the more you pay the faster you can go mantra alive and kicking [ORIGINAL: MrDemon OK lets look at the new 4C it only has 237BHp but now look at the weight sub 900kgs it does the 62 mph sprint faster than a Spyder. says all you need to know about weight saving
] Porsche 4342 x 1952 inc mirrors v Alfa 3988 x 1864 incl mirrors 
the point is you don't have to buy that car or change cars to get the Alfa 4C power to weight of 264BHp/ton just buy a Boxster spyder without the weight options, add a exhaust manifold and light weight battery and you can get a better power/weight than the 4C you will never do that with the added weighted up spec Spyder which can be easy over 40kg's more than a stripped out one. like it or not people weight kills performance under 90mph which is where most of us live, I have proven that vboxing my Spyder vs My R. Boring it might be to some , those are the factsORIGINAL: daro911Colin Chapman said all this back in the 1960's and stuck with it until he met an American in the 1980's and look what a dog they managed to cobble together CC should never have deserted his core concept of staying light at all costs Alfa 4C is a tiny car and I am sure if Porsche made a jnr league mini sized 2 seater they would have a serious problem making it slower than the bigger guys in the family to keep the more you pay the faster you can go mantra alive and kicking [ORIGINAL: MrDemon OK lets look at the new 4C it only has 237BHp but now look at the weight sub 900kgs it does the 62 mph sprint faster than a Spyder. says all you need to know about weight saving
Porsche spent £1000's on the 996 GT3 RS fitted carbon bespoke bonnets and plexi glass rear windows etc to just save 20kg's over a normal GT3, but yet people add in 40kg's Spyder weight back in. Don't even get me started on the bespoke Spyder wheel offset which give the spyder a wider track over a normal car , or the oem geo set up. I guess some buy for looks some buy for performance and driving spyderwhite

how do you get to 40 kg what tosh.lets forget pdk for a we know that adds extra weight.my manual full fat can only weigh 20kg more than your diet spyder.i have a/c and pcm extra that only adds back in 15-18kg!!so estimate my car weighs dry about 1295kg where as yours dry is about 1275kg!ORIGINAL: MrDemonthe point is you don't have to buy that car or change cars to get the Alfa 4C power to weight of 264BHp/ton just buy a Boxster spyder without the weight options, add a exhaust manifold and light weight battery and you can get a better power/weight than the 4C you will never do that with the added weighted up spec Spyder which can be easy over 40kg's more than a stripped out one. like it or not people weight kills performance under 90mph which is where most of us live, I have proven that vboxing my Spyder vs My R.

I saw this its old news at least a year or so as they are talking about new models in 2012? sorry I thought you was talking about a link to 4 models to rival fiat abarth,but that link is still old news and apparently not going to happen
I didn't say it was new news [:-]
quote "how do you get to 40 kg what tosh.lets forget pdk for a we know that adds extra weight" you cannot just "forget PDK" and say what tosh lol a lot of owners here have it and it's 25kgs more alone !!. AC is what 13kg more Normal chairs 12 kgs more PCM and speakers must be 4kgs more Carera S Wheels again 6kg's more Steel brakes, who knows, jury is out on total weight as the PCCB are larger but the rotation mass is smaller which give better acceleration and braking. then the smaller things like SPorts crono and even the PSE weight more than the normal one. so take all that into account on a PDK car and it's way more than 40kg's, of course there will be cars all in between those 2 figures depends on spec. nothing to argue or disagree about, those are the figures give or take a kg here and there from memory. I was trying to show a Spyder getting more BHP/ton than a 4C even though that only weigh 900kg,s you will never over come the 40+ kgs weight with BHP on a heavy weight spyder the mods are not there to give it that sort of BHP unless you bolt on some forced induction.
And your horrendous attitude rears it's ugly head again. Most people buy for both. It would take a driver far beyond your likely capabilities for the small difference in weight to make any difference. If you really cared about weight get rid of your passenger seat or, even better, buy an ariel atom. Otherwise stop bleating on about something which to 99.9% of people is of no relevance, unlike (say) having a radio.ORIGINAL: MrDemon I guess some buy for looks some buy for performance and driving
