Now you are telling me some random Russian garage with an ESS kit running a tiny V3si blower (That the 4.0 liter S65 V8 in the M3 is capable of easily maxing) with some nitrous thrown on top is making 1370 wheel horsepower on 98 octane gas with 14.5 psi of boost and nitrous? Oh that's funny.
If this shop wants to prove this, run the dyno in shootout mode please. What you see here is dyno manipulation at its finest. It's a load of crap ladies and gentlemen. First of all, RPI on a Dyno Dynamics with a full bolt on M5 plus the ESS supercharger kit only managed 576.8 wheel horsepower. So another 800 wheel horsepower is just some more boost and nitrous away? That isn't an optimistic dyno the Russians are just running, it is full on capable of miracles.
The V3si due to the volumetric efficiency of the S85 likely won't even hit 14.5 psi without being severely overspun. The blower is only listed as capable of supporting 775 horsepower at the crank anyway by Vortech:
ESS-Tuning themselves claims on 93 octane AKI (98 RON, like what the Russians are claiming to use) 640 horsepower at the crank with 6 psi of boost. Independent dynos have shown up to 560 wheel horsepower in STD correction or 540 wheel horsepower in SAE on a dynojet. That's a hell of a long way from 1370 wheel horsepower.
Ok, let's give the benefit of the doubt. Let's say 6 psi of boost gets the car to 560 wheel horsepower. That's about 23.3 wheel horsepower per psi of boost. Let's go all the way to 14.5 psi which would be roughly 757 wheel horsepower and beyond the capability of the blower but let's just ignore that. That still leaves over 613 wheel horsepower to be generated by the nitrous and nothing under the hood there shows the type of direct port setup with a good amount of race fuel being fed in to supplement the nitrous necessary to even approach a 1/4 of that output.
Ladies and gentlemen, this is simply someone with a Dyno Dynamics who played with the settings and is essentially trolling everyone. One has to be completely naive to believe some random tuner took an off the shelf kit, added some nitrous, and hit close to 1400 horsepower. If anyone for some reason believes this ask them to do this again in shootout mode. It will never happen.
Let's just put it this way, see that 729.8 number from the previous pull in the vidieo? It's still optimistic but at least closer to what the car is really putting out. We have the Miracle on Ice. The Russians now have the Miracle on the Dyno.
