Thumbs up QAS Germany: 40 hp gain w/ exhaust system + reflash

Hi,

one of our german forum members has been to "QAS", one of our fovourite tuners. They installed a catback exhaust, hi-flow cats and headers, finally they made an ecu-reflash. The gain in power is about 40 hp (at the crankshaft): 367 PS (= 372 hp) and 380 Nm (= 280 lbf ft).



This is our memberīs new video:
Please note: the co-driverīs weight is about 100kg

YouTube - Nissan 370Z 0 - 200 with QAS exhaust system
http://www.youtube.com/watch?v=yZ-WBlpwRRM

I suppose the run from 0-200 km/h takes about 19 seconds...

best regards
mike

+1 for pictures or videos. +40hp are insane gains.

As I have previously said Mike, VERY IMPRESSIVE! I'm not sure if this exhaust is available here in the states. Someone can chime in ....

I'm willing to bet if this is accurate that it has more to do with the gas they get and the tuning/timing. I'm sure the exhaust plays a big roll too but you have to look at the whole picture.

Here is what "Silo" (manager of QAS) wrote about this dynorun - I translated it for you:

Quote:

The QAS exhaust system is made up of the QAS headers, the QAS catalytic converters and the true dual catback. It was individually finetuned w/ the QAS Pereformance Plus ECU-Reflash.

367 PS / 380 Nm

Metering of power and torque on stock 370Z, before installation of exhaust system:

32x PS / 357 Nm

Unfortunately the metering was finished too soon, so the result was about 320 PS (316 hp). Itīs highly probable that the 370Z would have had a real output near 330 PS (325 hp), just like the other 370s before.

Performance through research!

This is the QAS catback exhaust:



Link: :: quantumautosport.com :: More than fast and furious! (german)


QAS true dual exhaust --> 1400 EUR
QAS headers --> 600 EUR
QAS cat. conv. --> 900 EUR

Note: stock 370Z: max. power @7000/min, QAS 370Z @7200/min

Itīs not some exhaust, the whole system was developed by Quantumautosport.com.

"Vmax" only switches off the 250 km/h-limiter.

"Performance" additionally changes the Target-A/F. This changes the long-term lambda correction, which is necessary to reach the maximum power gain of exhaust-systems and air-induction systems. The engine map wont be touched.

"Performance Plus" = "Performance", but w/ changed mapping. They promise some extra power gain.





regards
mike
