SHUF SHUF SHUFFING

[JoeyCleland]

Now that I'm running the DP Tuner im getting a shuf shuf shuff sound 3-4 times a second at high boost levels (25#+). It sounds like air escaping and makes my boost guage flutter 2-3 PSI. Is this turbo surge? Will it hurt anything?
Thanks
Joey

It is turbo surge, if you get the wicked wheel it and run the stock housing it will prevent it. Or if you get the bigger housing and run the stock wheel it will prevent this. Will it hurt anything I don't really know I have turbo surge and I have not had any damage done yet. If you play with the throttle you can work through the surge though.

I got the wicked wheel and I have not got it on yet. Maybe I will do that next weekend.

Yeppers...That's compressor surge. BigCountry was right. You can either install a WW, get the ATS compressor housing, or do both! Other than that, your looking at getting an aftermarket turbo if you wanna eliminate it.

I installed a 1.0A/R exhaust housing when I put in my WW and I have yet to experience any surge since...even at WOT going up hill....hitting 25-27 psi.

Just to let you know who gave me that info, it was Larry at DPP. I thought I had a boost leak. I called DPP and talked to Larry about it. He informed me it was turbo surge and told me how to correct it. I ordered the WW from him but I have yet to install it.

Yeah sounds like surge. Just to add it will shorten the life of your turbo. Basically the compressor wheel and turbine wheel don't know which way to turn or they stall and its hard on the bearings.

Thanks for that info vital, I guess I will get off my rear and install that WW sooner then I thought.
