Batmo Wheel
 

Im looking for input on a batmo wheel. I dont know much about them and was looking to get one because I heard that they increase the turbo whistle and spool up

They do whistle more. And improve spool time. It made a huge difference in the power ranges. Cleaned up smoke and cooled egt. And adds power. It was a huge pain to install though. The thing that makes it hard to do is getting the down pipe unbolted. I did it without removing the turbo which was a mistake that made it so much harder to do.

I don't have one but from everything I have read was that it increased the low end power but lost some on the top end. Basically comes on sooner and drops off sooner. Likely good for a daily driver where you rarely are at wot or high rpms.

I put one on my lb7 like was said before, "huge pain to install" a lot of labor but man I love it and with a bigger turbo horn, WOW.

A good friend of mine installed one and said it was awful to put in... But totally worth it!
