Donuts, Dyno, Launch Control - BWM M3 V8 Supercharger by VF Engineering

[vividracing]

After watching this video you will want to hit us up and get a supercharger for your M guaranteed! Their OEM quality, bolt-on VF620 kit as tested on our E90 V8 M3 put down 474rwhp on our Mustang Dyno using 91oct and a outside temp of about 100F. The Mustang dyno typically has a drivetrain loss of about 20% and in combination with the low octane fuel and high ambient temperatures, this car still rips, living up to the VF620 badge. The Vivid Racing BMW M3 is out fitted with custom Brembo Brakes, full Vorsteiner aero kit, H&R suspension, and a Agency Power exhaust system. Enjoy the launch control, dyno run, and smoke'em out donuts as we display the incredible power produced by VF Engineering.

Awesome vid!

[Brucewonder]

love your vids and the car. VF has the best SC system imo. After hearing one at bimmerfest in person. Oh that sound

[Powerbeast]

BWM? Lol

Best video ever!

Well done, car looks great and pulls nice !

[erm324]

nice vid! car sounds and looks great!

quick question, is that tranny slipping a little? not really sure why the car sounds like its lagging slightly between gear changes sometimes (especially on that last run), could be due to traction control or MDM?

isn't manual tranny better than DCT especially when adding all these FI/whp?

[GreeKon]

I'm confused. The kit is 620hp but the wheels only get 474?? Can someone explain to me why that is?? I know you lose a few ponies in the transfer of power...but that much??

I don't know much about blowers...that's why I'm asking.

From what I understand the MT can hold more power.

But DCT is also very durable.

The trans. def. definetly sounds like it is slipping. The shifts are not as crisp sounding.

After watching the vid for a second time I agree. I think it has to do less with the added power and more with the abuse put on the tranny (not saying the added power doesnt provide additional wear and tear). This is the exact reason I wont use LC with my blower, becuase once that thing starts slipping its only going to get worse

Great video

Thanks for the compliments!

As for the "slipping trans"- That's just wheel spin, guys. The tranny is holding up well, although that much launch control isn't something we'd want to do often; it is going to wear on the drivetrain. The car is driven primarily in "D", mostly highway miles, so the tranny shouldn't be an issue ever. We could run a stickier tire, but this is Dans daily driver. In day to day use, there's much less wheel spin of course.

On the subject of why the car's only putting down 450whp on a VF620 kit, that's a few factors coming together to produce a "low" number. It works out to like a 28% drivetrain loss; with ideal conditions we could probably see 490 on the dyno. We dynoed the car on a pretty hot day; baseline was done on a 95* day, and the VF620 setup was tested on a 100* day. On top of that, we have a Mustang AWD dyno, which reads lower than other dynos. This is because the Mustang dyno actually simulates real world conditions by loading the barrels. The car has to resist this load to turn the drums, which gives a lower HP number. In the end, comparing dyno numbers from shop to shop or even day to day is almost meaningless. The dyno is for tuning and for measuring gains. Speaking of gains, our car put down 312rwhp in 95* heat, and after the VF kit we made 474rwhp. That's a 165whp gain... On our "low reading" Mustang dyno. 474rwhp is low, right?

Gotcha...I now remember friends getting different results at different places. I guess it all comes down to the the tuning and getting maximum power. Thanks for the info!
