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

Clouseau · 08-29-2010, 07:29 PM

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 member´s new video:
Please note: the co-driver´s weight is about 100kg

YouTube - Nissan 370Z 0 - 200 with QAS exhaust system

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

best regards
mike

hmmm 40 HP from exhaust system??

that headers must be doing some bad *** gains!
Im interested.. any pictures/price on that headers?

ClemsonWill · 08-29-2010, 07:54 PM

+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.

thats gotta be $3k+ for 40hp at the crank?

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

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). It´s 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:

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

It´s not some exhaust, the whole system was developed by Quantumautosport.com.

QAS tuning now confirmed

22nd of Oct: Another 370Z with same setup on the dyno

Performance gain 43 PS / 22 Nm (42 hp / 16 lbft)

Headers, metal HFCs, catback, ecu reflash

After tuning: 359 PS / 374 Nm (354 hp / 276 lbft)

ninous26 · 10-22-2010, 04:51 PM

40hp crank not wheel. Seems about normal..

marino370 · 12-01-2010, 07:44 PM

HI , friends, I live in Italy , I fitted on my 370 a Exoticspeed + Hi Flow Cat , now I will want to reflash the ecu , It's possible with QAS ? wich of ecu reflash you raccomanded for me? Plus , Performance , or V-Max ?
Thank you

Clouseau · 12-02-2010, 03:19 AM

"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.
