Huh?All the OP is looking for is to get rid of turbo surge with the TA49. I don't think he is looking to run a turbo to its limit, or to build a balls to the walls 45 PSI car that races for big money.
He doesn't need a 6X BB turbo. Lol
Now if he wants one, great!
Need one? No.
6X BB = 6 (times) ball bearing turbo. LolHuh?
62 mm is where you want to be In regards to compressor size on 3.8 liter
Run a 49 and run a 62 mm at 25-27 psi with race gas...Check your iats and post back. No alcohol to mask the problem...
have you tried going to a larger ar?i do know that I am not out of turbo with the 49. My turbo surge is just out of control. Sometimes its just the flutter which doesn't bother me but it will surge so bad that it will feel like you let off the gas and it starts slowing down like you hit the brakes until it comes out of that boost range and it makes the engine stumble / misfire for bit. Its fine at every other throttle position. Also happens at the track after the burnout and almost stalls the car. I have tried turning off the meth thinking it was that but it is not. It just makes the car crappy to drive on the streets with any boost, its either no boost or blowing the tires off and no in between. My main goal was to replace this with something similar that wouldn't surge. I can only run down to a 7.35 at the track without a cage and I don't want to cut this car up it to nice for that. I guess if I did get a 6262 and it sucked with my converter I could always save up for a converter.
Its when you are at part throttle,Help me understand surging , is it when your at half throttle and it wants to bounce back at forth OR when going to WOT it takes about a half a day to get to your set boost level ? I guess I'm really lucky as I have never experienced that with either of our cars .
