[VR] 891whp/786wtq ZR6X Supervette - RHS, MAST YSI - Pictures and Dyno Graph! 
We have a long time friend and client of Vengeance Racing that has owned his C6 Z06 for awhile. He is a retired Command Sergeant Major from the US Army and he originally brought us his base C6 Z06 in for a VR custom cam shaft, ARH header system and an A&A V3 T-Trim supercharger system. That brought the car up a pretty good amount at the time but he ultimately he decided he wanted to go full out on this C6Z build.
The first step in the process was to drop the car off with Supervettes to give the car a wild look. He opted for the ZR6X conversion package and a set of Forgestar wheels to go with the new wide stance. Needless to say...he was able to go with some really deep concave wheels to complete the look.
After the visuals were completed with the outside, he brought the car back to us to really make it move as fast as it now looked. After some discussion on the options, we decided that a RHS 427 with some MAST heads and a YSI upgrade on the supercharger would get the job done. As you can probably imagine, the final result is a mean looking widebody C6Z that drives like stock and has great power to back it up.
Modifications installed:
- RHS block - standard deck - 427c.i.
- Manley Pro Series crankshaft
- Callies Ultra H-beam rods
- Wiseco custom pistons
- Katech LS9 oil pump
- Cloyes RHS timing set - MAST Motorsports 285cc LS7 cylinder heads
- Vortech YSI head unit & 8-rib drive system upgrade from A&A
- Alkycontrol dual nozzle methanol system
- VR 1000cc Fuel Injectors
- VR Custom Fuel System
- Painted LS7 intake manifold
- VR Valve covers
The result? 891.53whp and 786.90wtq! The best part is the car still drives on the street like stock.
Contact us at the shop for any questions on this build or any other C6/late model LS modifications.

Great car and great build, congrats!
I'm curious regarding the power output...I would've have expected more. Not to say that's not more than enough, but with that list of parts I would expect somewhere closer to 950rwhp.
Is there something holding it back or is the tune ultra conservative?
