Make my ZR1 faster
2011 ZR1. I just want a quick easy way to make it a bit quicker WITHOUT changing the exhaust manifold. Can I just buy a smaller pulley system? What gains could I expect? What should I buy? Thanks

C6 of Year Finalist (appearance mods) 2019
Easiest gains on this car would be gutting the cats, and a set of sticky tires. 
That said, I have a 2.6" Lingenfelter upper pulley/stock lower pulley combo. It was a bit of work to remove the snout and even more work to machine the new 10 bolt hub onto it. That said, I love the way the car sounds and pulls now. I also have 2" Kooks headers (catless) and an Attack Blue air filter. The idea was to keep IAT's down until I have more money to throw at cooling mods. Ha. Good luck.

That's exactly what I bought, along with reinforced bricks and an ATI super damper. I didn't want my car down for more than a couple of days, so that's the reason I went with the Lingenfelter mods. Pulls like banshee!!
