Porsche 996 mods
DRD RACING HEADS is involved with m96-m97 platform. Most of our research has been on our own Porsche 911 997.1 platform. This info has been retained on daily driven street cars, with all smog equipment attached.
The 997.1 system has some improvements, for the earlier on year’s machines. One improvement ended up being the ims bearing had been changed with a bigger bearing in approx year 2005 ahead, to manage more lots, and problems of this bigger bearing were very minimal to prior year’s m97-m97 engine. The ims bearing when you look at the 05 and later machines, ims bearing is changeable with a ims bearing enhance system from EPS . We advise driving the vehicle usually, and switching the oil every 5000 kilometers.
Engine oils we discovered that work well with these Porsche m96-m97 machines tend to be, Motul 8100X 5-40w for machines .
M96-M97 motors by design are designed for overall performance. The engine ended up being made to do, and performs perfectly develop the factory. By design, Porsche couldn't keep a great deal up for grabs for power in stock kind. After testing plenty of aftermarket items for those engines, we discovered little energy gain, as well as in some circumstances, we destroyed power with these bolt on services and products.
By design, the intake package is cold consumption design, and huge in atmosphere amount, and it has a lot of surface area to give the motors atmosphere demands. We found the stock environment package be effective exemplary compared to aftermarket heat bins that rob energy. The bmc air filter flowed the best of all of the filters we tested 30+ cfm over the other countries in the filters tested, and it is suitable for M96-M97 machines.
The fatigue system by design normally built to work for its providing application. For our evaluation within CA, we must conform to smog test requirements, so after marketplace cats and pet delte, tend to be unthinkable for certain. We like factory Porsche sport fatigue (PSE), the exhaust tone is dialed in for the motor, with no droning into the cabin. The x51 style headers have proven to deliver the very best overall energy curve the motor. Testing of this merge headers had lost bottom end power while incorporating some power up top. X go over pipes have lost power down reduced, together with small gains on the very best end of power.
One part of improvement is within the ecu tuning. Porsche had scaled back once again the ecu tuning for emissions and warranty proposes. By re mapping the ecu, the ability bend are enhanced, additionally the flat spots can be tuned aside, plus the motor can rev cleaner and much longer, to drive the motor to max power result. Drivability will also enhanced. There are numerous ecu flashes avaible available on the market. After testing numerous ecu flashes, we developed aside very own DRD ecu flash the gas avaible within the usa. Power is enhanced by adding a IPD manifold, along side a GT3 82mm throttle body, these things gained more power form 3000 rpms up.
We feel by setting up a 160 degree thermostat, lowers your chances of maybe not scoring a cylinder is considerably enhanced, and also by reducing cylinder temperatures your ecu will allow even more timing, resulting in approx. 5hp more out.
DRD Racing heads specializes in Porsche cylinder minds, as well as the cylinder heads can enhance power for certain. The down side to this may be the motor needs to be removed and cylinder heads must be eliminated. Increasing cylinders minds is only possible in the event that motor is being reconstructed or perhaps is having major service.
For everyday driven stock engines that require to pass through emission, we advice possess ecu remapped, including a bmc air conditioner filter, installing a 160 level thermostat.
In the event that you planning possess motor rebuilt, cylinders heads could be improved, and boring the engine to a bigger displacement will even reveal, ore energy regarding M96-M97 motor. 350-400 hp in the street is sufficient to possess enjoyable with for certain!
