OK There has been a lot of talk about it ,I finally did it today and i will tell you all the results.
Let me start by saying i have 02 dsg screw 6500 miles with the only mods were stock air box mod with K&N filter.
The temp today is a mild 78 deg. 50%hum. with bar. pressure at 29.95
and my local elev. is 1600 ft.
We did all testing with 91 octane pump gas.
When i arrived to the shop i allowed the truck to cool for 1 hour before we started the first dyno.
We also allowed the truck to cool on each dyno as it took about an hour or so to change the plugs and about the same to install the pulley and both belts to gator-back belts.
Stock dyno results :
(DYNO RUN 1 )316.7 hp 395.6 torq. A/F 11.50/1 @ 5200 rpm
Changed plugs to denso it 22 gap @.38
(DYNO RUN 2 ) 334.3 hp 406.0 torq. A/F 11.55/1 @ 5200rpm
Changed to JL 6# lightning pulley (measures 8.80" in the groove)
(DYNO RUN 3 ) 355.3 hp 464.5 torq. A/F 11.9/1 @ 5200 rpm
The truck really come alive now and you defiantly hear the supercharger howl.
No detonation at all
I am not saying that this mod is ok for anybody to run but i can say that i feel good about running it(not that i know much about these trucks )And i trust my Tuner that said for my truck and my situation this would be O.K.
I LOVE IT.
