Are Spyders Becoming Extinct At OPCs!

you can tune these cars to 350bhp quite easy as I said. all depends on costs, but changing the Manafold would give the biggest gains in HP and Torque, as the gen 2 cars have 4 cats in it. I would guess 15 BHp gain a a bigger torque gain just with that. Software will net you 10 to 20 bhp depending what else you have done. Software alone to get to about 335Bhp and if you did not have sports mode the software can be written to give you that built in. to tie it all in the vflow filter and larger intake plenum to round it off for 350Bhp.
Is there any physical difference between the Spyder and Cayman R engine or is the extra BHP just done with different software? Thinking about it, the Cayman has a wider exhaust doesn't it?
yes the exhaust has a larger dia and does sounds loads better. the engine will be the same. even some after market exhaust like Tubi are not as wide as the R exhaust. it's got to help. people have fitted the remus (which is the same as the R dia) to gen 2 cars and see a gain over stock even though there are no cats in the rear section, gains have still been seen. the mapping is better on the R any way driving both back to back, I guess they had a extra year to tweek and play with it to get 330bhp and make a better file. I do think the cars would fly with 350BHp and the extra torque over 300lb/ft torque is key on non forced induction cars imo. I est gains to be 15bhp + from the front section and 5 bhp from the rear for a over all 20bhp gain for a full system.
Daro - I do hope yur model has her Sun Cap On![ORIGINAL: daro911 [8D] We have a heatwave for next 10 days! I know unbelievable so if any of those current Spyders don't shift now what chances once the summer starts to fade all too soon for me and my 80 sunscreen [8D]

How mad is that having 2 different PSE dia's for the mechanically similar cars and forgetting any performance gains denying one the better sound track![:-] Is there no way an OPC or Porsche Specialist even couldn't remap a Spyder to R spec or wouldn't they have - be allowed access to that mapping[

It does seems crazy that Porsche developed a bespoke exhaust just for the R. I have driven the Spyder today more and the slight hesitation below 4k is def not there on the R under wot. So I also would like the R map on the Spyder. I will have a word with Scott who I have bought porsche maps off before and see what is possible. Would people be interested in a r map which works on the Spyder, If I put the time into it as he could look at both my maps and see what has been done different. He does make a map for a gen 2 dfi car though which gives you sports mode and 335bhp and more torque. So he may not be interested in making a r file for people. He does not mod the file, you re flash the whole ecu with the new file and can re flash your car back to the oem file at any time. Most maps alter the oem file, the maps I use don't touch the oem file. Tonight we get to find out what adding 45kg's does to the 30-95 mph time.
911 Turbo is awesome power for sure and very different in every respect to your "R" .... £45k for a £100k car doesn't sound to expensive [ORIGINAL: MrDemon I like the turbo 2 wheels and the ones on the silver Spyder , after Spyder wheels of course
] flat6 has a serious hankering for a 997 Turbo too [link=http://www.total911.com/coming-up-in-total-911/996-or-997-turbo/]http://www.total911.com/coming-up-in-total-911/996-or-997-turbo/[/link]
I just don't like cars getting on for 50k and 7 years old. Shocks, brakes, bushes, clutch's all on there way out and it could add a lot to ownership. Then when you see how fast the gen 2 is, it puts you off buying a £50k 7 year old car. The GTR then does every thing better, newer, cheaper.

But it is an old 987ORIGINAL: daro911Treat yourself Derek you know it makes sense[
A good comparison MrD. I've always wanted to know how they compared in a straight line fight. Might you consider the Spyder the slightly quicker platform if you wanted to wring every last ounce of performance out of the 987 i.e. looks like if it had the Cayman tune and didn't bog at all, the gap would be wider. Still, I guess there's little in it to make you go for a roofless, hatchless car, if the roof and hatch are working better for you in your day to day activities. Are you thinking of taking the PCCB's over to the R before letting the Spyder go?[ORIGINAL: MrDemon ok been out in both tonight at my local private airfield (yes I do have one), not the best for times as it was very hot, but same for both cars, and the point was to see which is faster not out right best time. 320 bhp/ est weight 1260kg + £35 fuel and me vs 330bhp/ est weight 1310kg + £35 fuel and me timed run was 30-115 mph, with WOT at 25mph and logging starting at 30mph to 115mph. The R map is better for a start, the Spyder bogs slighty at WOT at 30mph till you hit 4k revs. The R is very smooth on the map. SS is great, my shifting time from off to accelerating are only 2/10ths, I am normally 3/10th or even 4/10ths in some cars both cars let me do 2/10th shifts with out fail Any bets yet ??? graph goes a bit wobble in the middle due to trees but does not affect overall times at all. here are both cars, as you can see one has a slight lead till 95 mph then the other starts to catch back up.so The Spyder wins and at low speeds pulls away from the R , light weight here is winning the day even with the boggy map on the Spyder which I have never noticed before, but then I don't WOT at 25mph in 2nd ever. 90 mph is always a key speed with BHP, I have done enough vmax days in enough cars to see at 90 mph you need BHP to over come wind, the R picks it back up to match the Spyder then. so below 90 mph the Spyders less weight really helps the car get a lead. here are the speeds as you can see 30-40mph the R picks up better, the Spyder bogs a little (I did a few runs it did it every time, the R was perfect) then 40mph onwards the spyder pulls away. by 90mph the Spyder has 7 meters advantage on the R reaching 90mph in 192 meters vs the R at 199 meters. they both finish off at 440 meters at 115mph, I guess the coupe shape also helps once up to higher speeds.

]Some things to ponder. I don't think the Spyder engine has much in the way of engine development i.e. it is the Cayman S tune. Then, they did some development on the Cayman S tune to squeeze out an extra 10bhp for the R. Purely conjecture. On a separate note. When I had some thoughts about it before and noted in the Cayman R brochure that it said "Aiding in achieving the higher power peak of 7,400 rpm is the Cayman R exhaust system with a larger-diameter exhaust section between the catalysts and mufflers." , someone said to me that "The cayman and boxster also have different exhausts but this isn't for power, its because the cayman is a closed coupe and needs more sound deadening and tweaking of resonace to prevent boom in the cabin. The boxster spyder and black edition are therefore simply retuned standard engines. There doesnt appear to be any more info available on the R , but I suspect this is a similar situation. Regarding the updating of the software its possible for the porsche dealer to download the R profile into the PWIS workshop laptop and then reflash to a spyder. Its already been done with the RS60 software (303hp) into a standard 3.4 boxster (295) 987 gen 1 by a chap over in Switzerland."ORIGINAL: daro911How mad is that having 2 different PSE dia's for the mechanically similar cars and forgetting any performance gains denying one the better sound track![:-]  Is there no way an OPC or Porsche Specialist even couldn't remap a Spyder to R spec or wouldn't they have - be allowed access to that mapping[
