The VRP M156 3.0L Supercharger Upgrade is finally available!
After 3 years in development, Victory Road Performance is proud to release the most advanced performance upgrade for the M156.
On a stock motor, VRP has managed to make over 294WHP gains over stock with tons of room to grow! A bone stock C63 will make near 365whp on a mustang dyno. Keep reading to find out more about this kit and see what our M156 VRP Supercharger equipped vehicle made:
It’s all in the details…
First lets go over what makes the VRP supercharger kit the best upgrade for your M156!
For our M156 Supercharger Upgrade, we chose to do what no one else is doing and utilize the Gen 5 3.0l Whipple W185AX head unit. The most efficient unit Whipple has ever made. We are currently the only company using the true 3.0l unit. This head unit is capable of over 1300HP!
Once we had the supercharger sorted, we needed a cooling system to support it. We found this to be the main flaw of the kits currently on the market. How do we pack the largest possible intercoolers into the limited space we have available? We asked ourselves.. what supercharged V8 makes nasty power in its factory intercoolers in a compact package? None other than The Dodge Hellcat.
Using the factory Hellcat intercoolers has its advantages. We knew the potential power supported (Over 950whp) and the price was unbeatable. No custom intercooler is required, just one of the best factory cooling systems on the market direct from the dealership at a killer price. This is why this kit is priced where it is. The use of these coolers allowed us to cut the price of the kit by almost $1,500!
We have made this kit compatible with the throttle body upgrades we currently offer for the M156. The VRP Supercharger upgrade includes plates for both the factory 74mm and the 82/85s as well. We plan to offer the 92mm hellcat throttle bodies in the future.
The VRP Supercharger kit is also compatible with our modular crank pulley, and we have an 8-rib setup currently in development!
The Numbers Don’t Lie…
For our test bed we used a 2011 E63, The vehicle was already equipped with the following mods:
Before Mods:
- VRP Long Tube Headers with x pipe
- VRP Head Studs
- Titanium cam hardware
- VRP 93 Octane tune
The car put down very healthy before numbers:
– 439WHP
– 485WTQ
After the Baseline dyno, we installed the supercharger and intake for testing with the required cooling mods. All other mods were unchanged!
We took the car back to the same mustang dyno with the test 82mm pulley and put down 595whp basically on the first startup making less than 5psi. Based on those numbers we decided to step the pulley down to something a little more aggressive.
With a simple VRP flash tune for 72mm, we took the car back to the same dyno.
The 72mm Pulley produced
-659 WHP
-611 WTQ
With NO dyno tuning the VRP kit exceeded our expectations:
After Mods:
– VRP M156 Supercharger Upgrade Kit with 82mm throttle bodies
– VRP Heat Exchanger
– Bosch 010 Pump
– Cone filters
– Vrp Long Tubes with x pipe
– Vrp Head Studs
– Titanium cam hardware
– VRP 93 Octane tune
Cooling Mods:
The VRP 3.0L kit was able to achieve this incredible power with a simple flash tune, NO dyno tuning, and Just 1 log from the previous dyno session with the 80mm pulley where it made 595whp. What’s incredible is that the cooling system on this car is just about as simple as we could make it. A bosch 010, and a VRP heat exchanger.
No tank,
No meth,
No ice.
595whp 82mm pulley: Starting IAT 100, Ending IAT 117
An improved supporting cooling system including a VRP Superflo pump and Trunk tank would increase the power output of this kit drastically. We are thoroughly impressed by the efficiency of the Hellcat intercoolers.
We would like to note that our competitors release data on dynojet dynos, This car should make over 720whp on a dynojet. We do plan to take it to a dynojet within the next week on the same setup with some improved cooling, (A new pump, and an ice tank) A stock motor 720whp daily driven M156? Yes, please.

Is the aluminum coated at all? Worried it’s going to surface oxidize over time. First gen Maggies for the Corvette C5 were not coated and over time looked terrible; they later applied clear coat to preserve finish.
The Lids are Clear anodized.
What is the possibility of changing the intake port adapters to m113k and adapting this to that engine ? Now that would be cool. I know you already offer a kit for that engine but not like this.
If I have a p31 package c63 w204, what would you say the max whp possible would be with this blower? I was thinking of maybe selling my car to buy something else but now you have me intrigued lol.
THe P31 will not change the output of this kit. It will still be capable of about ~700 peak on a stock motor
Does this kit come with a ecu flash?
It does not
Is this kit compatible with 2010 Mercedes-Benz E350 and if soo do i need to upgrade any other parts .?
It is not compatible with the E350.
Is it compatible with the m156 that comes in the s63amg. It has 518 hp
This is a great kit. Very high quality. VRP’s customer service is unmatched. I would highly recommend this kit to anyone with a M156 engine. Thank you VRP for working on this fabulous unit.
