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 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

hmmm 40 HP from exhaust system??

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

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

In for UPDATES...........

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

i looked for about 30 mins...translated a few pages from german....just cant find it for sale anywhere....i know its a qas version of some exhaust? maybe im wrong

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:


This is the QAS catback exhaust:

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)

40hp crank not wheel. Seems about normal..

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

"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.

reflash Is what I need
