3 Years & Still Going Strong

**Full Disclosure, I am the owner of MRM Performance**

Reviewing this as I have been running the Pure 800 on my personal 340i for about 3 years now. I have nothing but good things to say about this turbo. I haven't had any issues with it in my years of ownership, and it's won be quite a bit of money from races. I'm estimating my current power at 680-700whp based off my 60-130 and 1/4 times. Spools up quick (3400rpm) and pulls strong all the way to redline. I'm currently running 31psi of boost on kill map. If you would like to see my experience with this turbo checkout my personal instagram (@SC_B5X), I have tons of race videos and other experiences with the turbo and car itself.

60-130: 6.66
100-200KMH: 5.73
1/4 Mile: 10.79 @130MPH (Spinning)
Dyno: 22psi Boost/16° Timing (I'm now running 31psi as I stated, but do not have any new dyno results)
