I've been debating to get DSC too, I have Bilstein B16 Damptronic, but haven't came across reviews on b16 + DCS yet. Currently, in sport and sport plus, it is way too hard as daily drive. Anyone has experience or input with this set up?

What's the difference between standard mapping and custom mapping? what are the pro and con?

MagicRat

I'd like to get an answer to the second question too. My car feels great on the stock DSC maps, but I do now have rather a lot of amplifiers in my frunk, so the weight distribution may have changed a bit!

Also keen to hear what OP thinks of the Akrapovic.

DSC Sport

There are a number of reviews floating around here on the B16+DSC; it's a popular setup. If I remember where they are/come across any I'll try to link them to you.

Not sure I fully understand your second question. We offer a standard tune file that is more than sufficient for over 90% of our customers, but the tuning software is always there to use and make adjustments as needed/wanted.

Hi Jordan,

I think I've seen B16 + DSC on 997 posting awhile back but mostly for track use. Haven't came across for 991 and for daily use. if you come across 991, please do share. I would like to know if the DSC can improve the comfort of B16 ride quality under normal mode. Is the ride quality similar to factory pasm in normal mode?

For 2nd question, Titleistaddict87 mentioned that Larry Cable send him Larry's custom maps which he would highly recommend over the standard. So I was wondering what are the difference?

Thanks

OK a little Off Topic here.

So I was thinking about this thread and the idea of a "Baby 911R" and how to actually buy one rather than build one. If the idea is to get back to a "driver's car" like the 911R then possibly a good starting point is the current base Carrera. Everything I have read indicates that it feels the most like past cars.

So, start with a base Carrera and lets call it the 911 Club Sport. Porsche could offer it with Radio Delete, A/C Delete and Rear Seat Delete. Add the cool lite weight door pulls that are available on the GT3/4, give it, 20" Carrera S wheels, six piston S brakes (PCCB as an option), Sport Design Mirrors, Sport Chrono and PSE and even SPASM (FAL as an option), the GT Steering Wheel, Short Shift Kit from the GT4 and then, remove most if not all of the sound deadening material and, this is a BIG one, give it lower final gearing. Sure top speed would drop but I'll never see 150 let alone 180. I'd much rather be able to wind it out in the first three or four gears on the freeway without fear of going to jail.

I'm sure they could "tune" the base engine with the smaller turbos to produce 15-30 HP more than the base but still less than the S and you still wouldnt be able to get the PDCC or RWS like on the S. They should be able to price it right between a base and an S and still make a profit since they are removing items like AC and the radio and rear seats and belts.

Now back On Topic - OP have you considered removing sound deadening material in your S to save weight?

Yeah, I don't think so. Porsche left 20whp/tq on the table because they couldn't figure out how to size the headers properly? Please post before & after dyno.

For me the stock DSC map was a little "floaty" for lack of a better work. On expansion joints and bumps I felt like there were one or two more oscillations of the suspension than I would expect. Larry's custom maps fixed that. I'll let him chime in if he's reading this but what he told me was his files are approximately 10% stiffer than the DSC maps but still a bit softer than even the regular SPASM setting.

As for the Akra, ran into a small problem with the install and waiting for new Torx bolts before I can complete. Hopefully they will arrive soon!

See above.

If I understand it correctly, Porsche is more concerned about the balance between reliability and performance not outright performance so completely expected from my point of view there is more power to be gained.

Churchill

Well, yes. But headers aren't a wear item or a source of reliability problems (well, unless we're talking about a Ferrari 355). Porsche can make the inner diameter and collectors any way they like with no effect on reliability. I'll gladly eat crow if someone posts a credible before & after dyno showing that bolting on Fabspeed headers produces 20 RWHP & torque.

On the 2.7 cars, SC's, 3.2 Carreras, and 964's, there are gains to be made from headers -- but only because these cars didn't come from the factory with headers.

titleistaddict87

Good idea but I wouldn't have a clue as to where to start with this. If anyone has some experience re: difficulty and weight saved I'd consider it but since it is a daily driver my idea is not to strip it out to track-car style.

Interesting point. I don't know enough about engine mechanics and headers to know what effect reduced outflow pressure might have on an engine. Please enlighten if anyone knows. I am seriously considering headers once I get this Akra on and check it out!

It's also a packaging and emissions issue as well. These motors are not tuned to the last hp, Porsche always leaves a bit more as they didn't know when they designed it originally for the 997.2 that it would be replaced after the 991.1. Checkout the GT3 forum and what Dundon has been able to achieve. They also have a GT4 setup and are working on a 991.

As for the sound deadening, I've tried to order my last two porsches without it; no go.
It's a nightmare to scrape off as the modern formula is sprayed/baked on and is very adhesive while getting into every nook and cranny.

I have my technicians pulling some Sport Header data for an S model that i'll post up shortly, but here is some dyno data from the Sport Headers that I have right now.

Here is data from a Base C4



Here is data from a GTS, as well as 3rd party dyno results from fellow forum member MagicRat

MagicRat

Yeah, they do seem to work...

drsubie

No one's mentioned perhaps the more transformative mod of all: carbon fiber wheels...

If your willing to spend $10k on a Akraprovic full ti exhaust (with negligible performance increase), then ~$15k or so for cf wheels isn't out of line (especially if you sell your OEM wheels)...

LTP

sprung weight def works, but not too practical tho, as durability!

addysdaddy

If u dont mind my asking, how much for the exhaust? I seem to remember getting a quote of around $10k and that's just for the parts. Thanks in advance.
