I am following all these blowers closely to replace the 1900 on my CTS-V. The 1.9 is great and did fine when pushed (700+whp) but I'd to run a little more power and not push this blower any further. I will be keeping an eye on the new heartbeat or potentially a ZR1 blower swap. Good runs OP, blower sounds sick!

 

In you guys dreams.

 

Weird ,can't you cut the flanges off Weesor headers and put LS flange on it ?

LS is a glorified weesor I've said that since even before I got either of my cobras and was building my 6.0 Fox...
