The factory motor has a new limit. As far as we know, 668WHP (dynojet) is the new M113k Stock Motor (no nitrous) record!
Read on to find out how we did it, and how we expect to push that over 700…
We are proud to announce the VRP 2.9L Whipple Supercharger Upgrade is now available! The single best upgrade you can do to your 55k AMG. This kit has already proven to be capable of over 300 HP Gains with supporting mods!

This kit is intended to be a supercharger conversion only, allowing you to upgrade your 55k as you go while preserving your previous investments.

This E55 was flash tuned based on 2 logs only. This car has never been dyno tuned and is running a FULLY OEM intercooler with no modifications.

VRP Supercharger Kit for M113k FAQ:
1. What are the power gains?
- A fully factory E55 motor will typically dyno 430whp on a Dyno Jet. The VRP Supercharger kit made 668WHP...that’s a 238WHP increase in power! We were able to achieve this on a STOCK Factory M113K intercooler. With 15% drivetrain loss, this is over 768 Crank Horsepower. Almost 300 HP over the factory Rating.
2. How is this different from your competitors Supercharger?
- Our supercharger retains much more of the factory components allowing you to save your previous upgrade investments. The VRP supercharger is ready to go out of the box with a 90mm and 92mm throttle body. Our Competitors supercharger is only compatible with 74mm and 82mm throttle bodies. Our competitor Rates their Kit At 680 Crank Horsepower, we just blew that out of the water.
3. Why do I need to send my core in?
- We are giving customers a trade in value on their old units to lower cost of the supercharger.
4. Do I need any other upgrades with this supercharger?
- We have prepared a Stage 5 Power Package that integrates all of the supporting mods needed for your VRP Supercharger Kit. If you are piecing the kit together, we highly recommend our Stage 3 Cooling Kit, an ice tank, long tube headers, and 630cc or larger injectors.
5. Will this fit the M113?
- Yes, we are currently working on a conversion kit for M113 NA customers that will adapt the kit to work with their vehicle with minimal modification!
6. Will my AMG engine builder placard fit over this?
- The AMG Builder Placard is not compatible with the supercharger by default. However, you have the option to affix your plaque to the kit using the same epoxy that Mercedes used on the OEM supercharger.
7. Will the stock motor be able to handle this Supercharger Upgrade?
- Yes! Our test car was on a fully stock motor, Stock heads, Stock Cams, No head bolts, and fully stock bottom end
Run it down the 1/4 mile 20 times in a row and if it doesn't blow up I'll be a believer. The last whipple'd E55 posted on this forum years ago (user: gadget) blew up after a couple 1/4 mile passes. Sir-boost-a-lot was working on his Whipple'd CLS55 but we never heard the end result. By no means am I trying to put down your efforts, on the contrary I admire those who continue to build on what will soon be a 20 year old platform.

His temps are probably still lower than yours, and this car has been thrashing on 18.5psi on a stock blower for a year now. The tune is mild, and the car is loving it. Run your car down the track 20 times in a row, and if it doesn't blow up ill give you a pat on the back... Not sure why anyone would do 20 back to back runs "in a row" in any car. But

Why? It's called "proven reliability." A stock E55 could do it, as could most any car. I could put a 350hp nitrous fogger setup on my E55, make a couple glory runs and say wow! But that doesn't mean the motor can "handle it" for the long term. You are claiming a new power limit for the stock block after all. You just haven't proven it, is all I'm saying. Do you know why MB doesn't like their cars being tuned in the aftermarket ? Aside from the obvious warranty expenses, I was told they have a reputation to protect...and their engines must last 100k+ miles and be just as reliable as your neighbor's E350.
Very cool. I'll be following this closely as these work their way out into the wild. Good job, and thanks VRP for continuing development on this platform. Its a strangely tough crowd here on this forum.
Hey cool, I just realized that ya'll are down in the springs. I'd love to come visit when I finally break down and start modding the wagon.
Sir boost is still going strong with that car.
On a side note the factory intercooler is pretty restrictive from what I have researched so wonder what the boost would be with a better cooler like the Weistec .
Yea ,second that.....A fantastic blower pushing through old school technology kinda counter productive. But....saves a decent amount of money on the kit in the end.
Then again if your turning up the boost you will need more heat control.
Also interesting that it picked up 148 horsepower from just the blower upgrade.
I don't know much about whipple products but the oem IHI unit is well out of its efficiency range pretty quickly when turning up the boost so it could make sense that the IAT's are within a somewhat reliable range with this setup. Look forward to seeing the longevity and driveability reports. Unfortunately a lot of issues seem to come out when trying to tune various forced induction aftermarket upgrades, even just getting a throttle body upgrade to play nice seems to be a challenge on this platform. I hope the kit comes with an all wheel drive bolt on upgrade
