Ess 620 Fuel Consumption
Guys,
Contemplating on installing a ESS 620 on my 2013 M3, since the 650 is not really that much more gains vs price. The question I have is how much more fuel consumption for a daily driver I should expect to see? As a law abide citizen of course |

It will be similar to stock if you keep the revs low. The centrifugal blower doesn't even build boost until ~4.5k RPMs.

I think on my old stock 625 I got 19.6MPG on a 1000 mile drive, wrote it all down since changing the fuel injectors throws off the cars onboard MPG monitor and can't be used.
So steady at HWY speeds you might loose 2MPG or so vs stock

A very simple division between the two is low-end power that drops off with a positive displacement superchargers vs. linear power with a centrifugal type supercharger that increases with engine rpm. The linear curve from a centrifugal supercharger compliments an engine’s existing power band, instead of working against it like a roots or twin-screw. Another significant benefit is that the efficiency of a centrifugal is much higher, meaning a smaller amount of the work that goes into turning the compressor gets converted to heat with a centrifugal vs. a positive displacement supercharger, and especially so vs. a roots type supercharger. So it takes less energy to make power with a centrifugal, and the power that is created is much more usable power. Here's an ESS-625 dyno showing the boost building - http://www.bigdynodatabase.com/DynoG...0068-DLSJ5.jpg

A coworker moved from the ESS 625 to the ESS 650 kit and said the difference was noticeable

I daily my 625 kitted car and get 13-14 avg mpg per the obd/stalk indicator. my commutes are in-town about 5-7 miles per day. if i go out on a drive with friends and play, it's in the 10-12 range.
I don't see the kits having much difference in mpg, when commuting my boost readings are less than 2 psi max boost(unless i have fun). Always go with the highest kit possible when purchasing the first time, it saves money in the long run and you will always want more power.

So if the fuel consumption is not that much more I guess now is decision making ESS 625 or 650. Is the 650 really worth the money. I don't see too many of them in the forum 75% is ESS 625.

It's a tough call as you're paying $1,700 extra for +25HP and +10ft/lbs when looking at new. If you can find a used one that price split becomes even less so it would be worth it. You're also adding 1.5-2.0 PSI increase from 625 to the 650. I went with the 625/410 kit to get the best of both worlds: liquid intercooler and really solid numbers for $900 more than the 595/395 kit with slightly less boost.

It builds boost like a dream and the curve is so addicting because its so controllable. It compliments the car so well you will regret not doing it sooner. The only downside is that you enter speeding territory so fast, so less time to enjoy going through the gears. But with High RPM motor and solid horsepower numbers makes it perfection. I use an ACM p3 guage which isn't bad

Also, I assume you mean the diverter valve and not a blow off as that's what comes with the kits.

Yes, more psi and more stress. I firmly believe the 625 kit is the most balanced, and it's hard to imagine someone redlining that kit and thinking 'this is not fast enough'

Yeah, don't do a BOV. Keep the kit completely stock
