ExMB: More information, please, in English.

 

Thats all I got from that posted link

 

Unfortunately... even with a tune and OPF delete the engine still sounds like a lullaby.

Someone please find out how to make this sound like the 981 GT4/Spyder. Even without the overrun, I’ll take it.

 

:

This jewel had been picked up by another tuner, it comes to us with the modified exhaust without the #OPF system but in terms of engine management we found it exactly as mum #Porsche did it.
Maybe because there is the old legend that mapping the aspirated engines is useless?
Here are the results obtained after our intervention on this new 4-liter naturally aspirated 420hp engine from #Porsche.
We move the rev limiter from 8,000 to 8,300 which allows the gear change in the area 8,200 instead of 7,900, perfect speed in order to make the most of the peak power in the fallout of laps after the change.
In addition to the pure performance, the irregularities and uncertainties at low revs are practically eliminated giving a full, fluid delivery and with a constantly higher torque throughout the rpm range.

 

A 981 doesn't sound much louder through a GoPro placed on the steering column. The missing sound is in the back box of the exhaust because noise regulations. Porsche couldn't make it louder if they wanted to. The engine sound itself (not exhaust sound) for me is way better from the higher revving 4.0 than the old 3.8. (and I actually have an old 3.8 that goes to 8K)

 

I understand that their hands were tied due to regs on volume level but this doesn’t explain why the engine seems to have lost so much character.

If you have been in possession of a 981 GT4/Spyder and a 718 GT4/Spyder than you’re in a better position than most to comment, and perhaps in cockpit the 718 is as or more satisfying, but that one definitive video for me on YouTube had an “exhaustoff” between the two cars and on the outside there is plainly no contest. All the blat and aggression in the 981 is missing. Porsche race cars have that sonic signature and a GT car is supposed to be of that lineage. The 981 captured it very well, and based on what I’ve heard (admittedly online mind you) the 718 doesn’t.

 

I've driven the 718 GTS 4.0 on track and on the road and I don't feel any character has gone missing. If anything I actually prefer the new one. The way it behaves and the mechanical noises it makes higher up the rev range are IMO a step closer to the GT3 engine than it was before. Slightly muted, but it's there. It also doesn't drop off in power like the old car did towards red line, which adds to the fun.

The only people "missing out" are people outside of the car, not the ones inside of it... after test driving the GTS 4.0 I went and put an order in for a new Spyder... which I had not really been thinking about before.

 

Wow! Look at that! Someone with actual knowledge posting! I don't think I've seen that before on this topic.

 

Can't wait to see the griping about overrevs in range 1 and maybe 2...

 

Hahaha, yup. That and gearing. If people thought the gearing was long at 8k rpm, 8300rpm means 2nd gear will top out around 90mph. Like driving a viper but with only half the torque
