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

    Hello VRP crew, I am from Florida and I have a 2006 E55 AMG with 209,900 miles on in, I believe I am the 2nd owner. my question is would the Whipple 2.9L supercharger handle a cross country cruise ? as in I plan to drive the vehicle from Florida to California and back for vacation. Besides offering a lot power what is the lifespan/maintenance on it ? thank you !!!

    1. Philip Lataille

      Absolutely, The whipple superchargers are used on hundreds of OE Models from dodge to Chevy. Maintenance is no different on this kit than the factory unit.

    Hello again VRP crew, I forgot to mention one good question, this is Gabriel from Florida, so the description mentions about an all “”stock”” E55 AMG engine block, heads, and cams, BUT can a 5 speedshift (722.6) “”stock”” transmission handle the beast output of the new 2.9L Whipple supercharger ?! Again thank you !!!
