And can anyone tell me the difference between the wicked wheel and the stock wheel that's in my truck now. It's a 99.5. Thanks for any help in advance. Oh, and I've had a AFE stage 2 intake on my truck for over a year and it just started making that ch ch ch sound this past weekend.
Yeah I never experienced the turbo surge until I was comming home from Abalone diving, and I was pulling a high grade on HWY 20 and I was at WOT and it started the ch ch ch.
I can't tell you exactly what it is, but it's something like the turbo wheel can't support the boost that is being built at WOT and the boost starts pushing back against the wheel.
As for the Wicked Wheel it is only about $80-90 bones and SUPER EASY to install. There are a few tech files on here that show exactly how to do it, and also at least one video. You only need to replace the housing if you want to build more boost, but the wicked wheel can easily handle the boost of the stock housing. PLUS they sound really sweet (they are loud) As for the difference between stock, it's the number and the degree of the fins on the wheel that make a difference. Where all the fins on the stock wheel are the same length, the fins on the wicked wheel alternate long, short, long, short.
