[VR] Daytona Sunrise Corvette C7Z06 - 724whp / 723wtq - Pictures and Video Inside!
It's no secret now that the C7 Z06 is taking nicely to mods. With the supercharged LT4 platform, we are able to tweak boost and open up the air in and out of the motor to really stretch the legs of the 6.2L V8 and 1.74L Eaton blower. This customer of ours came to us with a brand new Daytona Sunrise Orange Metallic Z06 ready to make some more power. This particular customer was already pretty experienced with Z06 mods as he had us build his previous orange Z06 into a 600+whp 440c.i. car that did 164mph in the 1/2 mile and 10.2 in the 1/4.
For those of you that have not seen the Daytona Sunrise Orange Metallic in person, it is a truly unique color. In the shade to takes on a burnt orange look but when you get it out into the light the organic and metal flake really come alive. It is a color that is extremely hard to capture in pictures but looks absolutely amazing in person. When you mate that color to the gloss black wheels from 360 Forged, it makes for an aggressive look.
For this round of mods he wanted to make low 700's at the tire. Through the development of our shop Z06, we knew the exact path to get to that number so we got to work on upgrading the pulley's, installing one of our custom grind camshafts and along with some work to the heads and other supporting mods...made our way to the customers goal.
Modifications Installed:
VR Custom Camshaft Kit (non-DOD, retains VVT)
ARH 2” Longtube Headers w/Non-Catted X-Pipe
B&B Fusion Axle-Back System
MGW Short Throw Shifter
RPS Twin-Disc Billet Carbon Clutch
Halltech CKNZ Carbon Fiber Cold Air Intake
VR 2.35 Upper Pulley Kit
Innovators West Balancer
VR Overdriven Lower Pulley ring
NGK Spark Plugs
VR Heat Sleeves
VR Milled Cylinder Heads .025”
19x12 / 19x10 360 Forged Mesh 5 in Gloss Black w/ Toyo R888
The result? 724.35whp / 723.90wtq on 93 octane without the help of methanol or any other adders! To make things even sweeter, this Z06 has road manners just like stock even at this power level.
Here is a video of the B&B Fusion exhaust system with the valves both closed and open.
For any questions on this build, any C7 Z06 performance modifications or any other late model LS performance mods, give us a call at the shop.

Car looks killer.
Great job guys. I bet it's a beast and a half to drive.

No trick question - just an honest request for information re the concerns of a lot of folks.
Obviously you are aware that some of these cars are having issues with overheating under varying conditions, including even roll racing at night.
I say some, because there appears to be a high degree of uncertainty as to the underlying cause/fix - not all Z's experience the problem under the same circumstances.
I guess the question may have been better stated as follows:
In your planning for the mods, did you make any preparations to account for the resulting additional heat generated and its potential impact and if so, what did you folks include/change? And was there any subsequent use of the Z that might have indicated whether or not this particular Z is now or was before susceptible to the issue?
Your response above makes it seem that the likely answer to the above two questions is probably "no"???

Love that look, especially the wheels and the stance of the car.
I'd also like to ask that IF your customer wanted to road race the car, what are your thoughts re: a secondary engine oil cooler at a minimum to keep oil and water temps in control?

We have built/modified over 20 C7 Z06s now and have not seen a single issue with mechanical over heating. Most all of our builds receive a 160* thermostat to offset any concern.
With regard to IAT2s... This isn't an issue of "over heating", but the ECU will pull timing based on inlet temps and this is standard operation for any forced induction vehicle that we have ever worked on.
The vehicle featured in this build thread along with our shop C7 Z06 both have seen a fair amount of abuse including 1/4 mile- 1/2 mile racing and quite a bit of "spirited driving" thru the mountains including Tail of the Dragon with no issues to speak of at all.

Can't be sure of what I'm referring to because no one seems to have nailed down the cause - you must know that.
Based on incidents where the problem presented itself, the data suggested the IAT2 temps were not an issue.

You do not know the question you are trying to ask? You asked me if we considered the over heating issues? What over heating issues are you referring to? Do you have any links I could catch up on that may better explain your concerns? As I said, we have not encountered any issues to date and have been working our cars very hard to find any issues possible.

It appears that you are not following the myriad of threads on the issue I am referring to or that you give no credence to those report, so I'll drop it.

"Overheating" while "roll racing at night", lol, okay.

You are correct, we do not spend as much time reading the forums as we do developing performance parts/packages for this community. This includes extensive R&D/abuse/data logging to ensure proper operation and performance of your vehicle.
Show me another shop aside from LMR that purchased a $100,000.00 vehicle for R&D purposes as we have....... I am sorry I was not able to answer your question to your standards.... I explained both scenarios above and stated what we have experienced with each.
Have you experienced any "over heating" with your C7 Z06? If so please provide me with as much detail as possible and I would be happy to provide you with my thoughts. You can reach me at the shop by calling 678 513 7105 or emailing Ron@VengeanceRacing.net if it is easier.

on your mods. 
C7 Z06s were designed to meet a target of "car won't overheat" if driven by a pro driver in 86 degree weather for a tank of fuel.
This is as described by the head design engineer.
Drivers exceeding these design parameters are seeing oil temps near 320 degrees and water temps near 250 degrees and their cars are going into limp mode to avoid catastrophic engine failure.
These limits are exceeded more quickly when A8 cars are driven in D because the transmission programming keeps revs "inhumanly" high.
People who drive their cars on road courses could really use enhanced cooling to avoid having to cut track days short when things get hot.
Not everyone who drives a Z06 on a race track is exceeding the design limits of the car.
Maybe this an opportunity for the after market community, but I suspect that there is a greater market for enhancing power for people who will never exceed the design spec for cooling.
