Cayman GT4 Is it quick enough?
Discussion
Nice to see my thread resurrected after a short pause whilst everyone gets a few miles in.
I am still of the same view that I had when I started this thread that the standard GT4 just doesn't feel quick enough at the top end of the rev range. The overall package is brilliant but I just feel it could be that bit better!
A really good Porsche n/a engine should sing with joy at the top of the rev range and this tune just doesn't. This combined with the abysmal fuel economy (worse than my 997GT3 or my 991GT3) makes me convinced that it will be easy to liberate the extra top end fireworks.
How brave do I have to be to toss the warranty into the bin and fit the induction kit, exhaust and remap that people are raving about in America? What is the likely effect on resale? I have modified and raced cars for years but generally I start with something a bit older. There is defiantly a psychological barrier to hacking away at what is a lovely (brand new by my standards) car.
Or sack off the GT4 and get another GT3???? Tricky.
Off to Spa on 6th May with Goldtrack. It will be moan moan moan about the lack of grunt all the way up the Kemmel straight and then forget to breath all the way back down to La Source
happy days.

2150 miles now. A 3 hour trip from south to north wales tonight again. This talk about the flatness at the top end isn't as much of an issue for me as the flatness of torque at about 4900-5300. It pulls like a train up to 4800-4900 and it's great to use the ample torque lower down but I get frustrated with the flatness between 4900-5300. After 5300-5400 you get the second wave. Really annoys me but then I guess that's what happens when you effectively detune the standard unit. Are people of the same opinion? It's ok if you're gunning it and keeping it about 5500 all the time but then you're travelling at serious speeds for the road. You don't notice it so much in 2nd but very obvious in 3rd.

I'm not sure it's entirely true that you wont invalidate the warranty inside the manufacturer warranty period if you modify it. I've heard of several cases where Porsche Germany have requested photos of certain parts on cars before agreeing to cover faults. I think the Americans have a well documented law case that states manufacturers can't refuse warranty on a part as long as a modification doesn't directly effect the part being claimed. Or something along those lines. Plus I think they are just generally more laissez faire about the whole thing and just accept the consequences of their actions.

Torque curve shows no difference at 4700, 5000 or 5500 rpm.....

I love the way the Americans have brand new cars (zero miles) transported straight from the opt to places like sharkwerks for 'improvements'
Over here that sort of approach would be met with gaps of amazement and ridicule - over there it's the norm, the done thing
Agreed. I wish Brits would get over their hang ups over original paint stickers and resale values. Just modify the damn thing and enjoy life.Over here that sort of approach would be met with gaps of amazement and ridicule - over there it's the norm, the done thing
I claimed for a new stereo amplifier and new air-con condensers with no problems whatsoever on my 997 GT3.
At the time, the warranty had been transferred to me from the original buyer of the warranty and I had no dealings whatsoever with the OPC who did the work prior to them accepting the warranty claim.
The car had aftermarket radiator grilles on the front to protect the rads from stones, it had RSS engine mounts, RSS toe links, RSS Dog bones, a bypass exhaust and rear brake ducts from the 997.2 RS. It was also wearing non 'n' rated tyres and none of these caused a problem when claiming on the warranty.

Yeah thats right. If I was in the fortunate position of having a new Cayman GT4 with a brand new 2/3 year warranty I would be tracking it and spanking the s
t out of it and modifying it safe in the knowledge that as long as the car is serviced according to the book I am covered. 
Well had mine round Silverstone today, first track day in the GT4 and also first time round silverstone... brilliant car. Yes not a full hardcore track car...but brilliant having to relearn weight distribution and trial braking as my background is lightweight stuff but awsome had a wonderful day. Felt better when I learnt the White GT4 which just disappeared was a clubsport on slick...!
Loving the car.. but yes another 50bhp wouldn't be missed, but isn't that always the case?

Picking up an old thread, has anyone released some of the top end potential from the detuned GT4 engine? Ie a decent remap?
Coming from a lightly remapped (optimised for 99 Ron fuel) manual e92 BMW M3 I certainly find the GT4 runs out of puff a bit at the top end.
The rest of the package is great. I don’t have a problem with the gearing everyone mentions, I think it just needs some more “rip saw like” aggression and zing in the last 1k revs like the best na engines have when you chase the red line.
