eas | Joe's 400hp M3 sleeper has hit the streets!

Sleeper
sleep·er

Noun:
A person or animal who is asleep.
A person with a specified sleep pattern: "he was a light sleeper".
A term often referring to what appears to be a ordinary looking stock vehicle that is anything but stock under the hood.

A sleeper (US English) or Q-car (British English) is a car that has high performance and an unassuming exterior. Sleeper cars are termed such because their exterior looks little or no different from a standard or economy-class car. In some cases the car appears worse due to seeming neglect on the owner's part, typically referred to as "all go and no show". While appearing to be a standard or neglected car, internally they are modified to perform at much higher performance levels.

We're particularly a big fan of sleepers, it seems the 400whp barrier has been broken, with a new beast is now hitting the streets.





2011 BMW M3 DCT (Alpine White)
Dynorun 01: Baseline
Dynorun 12: Macht Schnell Stage 2 Intake Charge Kit, Macht Schnell Performance Underdrive Pulley Set, Stock X-Pipe/Muffler
Dynorun 19: Macht Schnell Stage 2 Intake Charge Kit, Macht Schnell Performance Underdrive Pulley Set, Challenge Race+ X-Pipe (no cats or resonators), Stock Muffler



Overview
- Approximate +49 peak hp gain & 28ft-lb TQ from simple bolt-on mods
- Increased acceleration, throttle response
- Aggressive intake & exhaust note
- OEM+ look & appearance
- Approximately 2-3 hours install time

This goes to show the 400whp barrier is obtainable, without needing to break the bank. We'll also be playing around with the Evolve tune in the upcoming weeks on similarly-equipped M3s to get some comparative data to share.

Enjoy!

Nice dyno chart, but I'm not sure if an E92 M3 w/ 50 more HP falls into the definition that you provide...
