2008-2013 Cadillac CTS Performance Mods Discussion, Any Late model 3.6 CTS owners want 100-150 more HP? in Cadillac CTS Second Generation Forum - 2008-2013; A member on here is almost finished with his 2011 CTS so he should have some feedback shortly....
I lost 3# boost when my original crank pulley broke. I'm not happy with the lost performance. It's a huge difference!!
I'm going to have to purchase a smaller SC from Vortec to gain back what I lost.
Stock Mustangs and Camaros will now beat me without any difficulty. my girl's tuned SHO even beats me now. That wasn't the case when I was running 10#
50HP makes a huge difference. My methanol injection kit is useless until I get the extra boost back
The AWD system has held up well even when I had 10# boost. No problems with the drivetrain.
I wouldn't go with 6-7# boost especially after knowing how my car ran with 10#.
