Posted 30/08/13 01:46 PM Share Posted 30/08/13 01:46 PM Hi,Hoping someone can shed some more light or point me in the right direction here.I have a FG XR6 Turbo auto.My car made 312rwkw with the following mod list:4" dump - 3.5" turbo back exhaustCold air intake (pod enclosure)Larger intercoolerRebuilt turbo12 PSI Actuatorid1000 injectorsWalbro 400 LPH in-tank fuel pumpIntercooler piping w/muffler deleteValve springsSCT XCAL 3 tuned on 98 The tuner said the car was pinging up high so he had to lower the boost and couldn't add as much timing.He even tried adding octane booster to see if it would help.I would have thought with the mods mentioned I would expect to see 330 - 350rwkw.Does anyone have any suggestions or thoughts?Cheers.

stevanford Member 268 Member For: 12y 9m 7d Posted 30/08/13 10:01 PM Share Posted 30/08/13 10:01 PM Power sounds about right for a standard turbo fg xr6 turbo though you mention a "rebuilt turbo". Rebuilt to what specification exactly ? Link to comment Share on other sites More sharing options...

They say the small turbo can go to 330rwkw but that's depending on the dyno. Link to comment Share on other sites More sharing options...

Another FG went 350 same dyno but the tuner was really leaning on it. Anywhere from 310 to 335 is about right depending on the dyno as has been said.

But I wouldn't think you'd get to 350 unless its an F6 turbo or you're using E85.At 312 though, I bet it's still a beast !
