      Our previous low compression / Precision 71 turbo powerband in the track M3 took nearly 2 seconds to get back to full power after exiting a turn. Even with that issue, the car was still extremely fast because it had enough power to make up for it. Now we have the best of both worlds with instantaneous power all the time. We're running a smaller 6766 turbo with a high compression 9,000rpm rev limit motor and we're running even more power than we used to. Here's a dyno of the car to 9,000rpm and a short clip of it on the street. For comparisons, I overlaid this dyno with the HPF stage 1 powerband on race fuel. ...

      G-power released their new X5 N62 V8 supercharger system. This Stage I setup boosts the X5 from the standard 355 horses to 450 horsepower, a gain of 95 horses. This is achieved with an ASA T1-518 centrifugal supercharger at 6 pounds of boost. The kit includes larger capacity injectors, an air to air intercooler, and of course a custom tune. Great to see another forced induction option for the N62 V8. BimmerBoost vendor Precision Sport carries the kit, contact for pricing. ...

      The new F10 M5 is the current automotive hot topic as a new M5 model often is. Here is a very cool and creative advertisement on the part of BMW Canada. This "Bullet" commercial essentially has the M5 play the role of a bullet that is shot out and goes through various objects at high speed. The slow motion capture as the M5 hits its target is absolutely perfectly done in exceptionally high quality. Definitely worth watching. ...

      Here is a comparison many of us have been waiting for, seeing the manual CTS-V go head to head with the new F10 M5 also with a manual transmission. Road and Track picks the M5 in first place and it is difficult to disagree. The M5 is the better car here offering a performance advantage as it should considering it is the car to come to market later. The M5 outlaps the CTS-V by almost 1 and half seconds (1:21.01 to 1:22.44). Handling clearly being in the M5's favor with lap times, skidpad, and slalom numbers all surpassing the CTS-V. ...

      It was only a matter of time before this happened, the manual will be dead in the M5 after the F10. The manual in the M5 already was eliminated everywhere in the world except in the USA starting with the previous generation E60. The numbers simply do not justify BMW continuing to offer a manual in the M5 as orders with the manual option are declining. BMW M's head of engineering Albert Biermann stated, "Last year, maybe 15-20 percent of our M5s in the U.S. were manuals and maybe this year it will be 15 percent. It's declining. The trouble is that nobody wants it in Europe or anywhere else, so this will be the last time we do it, even for the hard-core U.S. buyers." ...

      The new F12/F13 M6 is a beautiful design, no doubt about it. However, an M model is supposed to be about performance and engineering over style. This new M6 cabrio was supposed to be slightly lighter than the previous generation E64 based on the BMW press release stating a 4312 pound weight. Well, Insideline tested it at a staggering 4,495 pounds. This is 122 pounds heavier than what they tested the previous generation M6 convertible at which was not exactly a lightweight itself. ...

      Congratulations to BimmerBoost member djborya (Boris) who managed to break the 8 second barrier in the 1/4 mile with this turbo E30 BMW. As far as BMW's in the USA are concerned, this is the only one we know of to get in the 8's that is not a tube chassis dedicated drag car. The vehicle has a full body, BMW independent rear suspension, and runs E85 fuel. The 80mm turbo makes 836 horsepower to the wheels through a 2-speed powerglide transmission. ...

      By now everyone has heard of the Vorsteiner GTRS3 carbon fiber widebody kit for the E92/E93 M3. Vorsteiner has updated the design of the kit releasing the GTRS5. The front and rear bumpers received a redesign with the front addition vertical vents for improved air channeling. The rear bumper gets a slightly longer diffuser to help create more downforce. The E46 CSL style trunk also receives a redesign that looks much cleaner. This GTRS5 kit is limited to only 40 units worldwide and we expect similar pricing ($25k installed) to the GTRS3 setup. ...

      Tuning for the new N63 twin turbo V8 has been a bit hard to come by from sources other than Dinan. Unlike the S63 in the X5M and X6M, it seems the N63 has been harder for tuners to crack. Not Dinan however who has updated their offering to a Stage 3 tune. Dinan does not publish dyno numbers with their products (which we definitely do not like) so we want to thank BimmerBoost member alextremo for taking the time to dyno his rear wheel drive and manual 550i on a dynojet with just the tune only. ...

      The Audi R8 V8 really is not all that fast of a car for the money. It's beautiful, but straightline speed is not its forte with a DCT M3 being faster stock for stock as well as a Carrera S even with a smaller motor with six cylinders to the R8's eight. The 1M pulls the R8 from a roll easily in the first race but it looks like the R8 got on it late. In the second run the R8 gets a slight lead only for the 1M to bridge the gap. The cars are close but with the 20 inch HRE's on the R8 and power going to all four wheels it is begging for boost to show what it is truly capable of. ...

      In the absence of a BMW M7 (which likely will be coming) the Alpina B7 is the closest vehicle available to such a car. With the 7 Series receiving updates for the 2013 model year Alpina is not resting on their laurels updating the B7 exterior as well as the Alpina custom N63 V8 under the hood which gets another 40 horsepower. This horsepower boost was necessary as the to keep distance from the 750i which got a bump in horsepower to 450 from 400 as a result of a bump to the N63 V8 for the new 6 Series GranCoupe. ...

      This is becoming a disturbing pattern although it sure is looking good for Audi. Just earlier this month Car and Driver picked the S6 over the new M5. Insideline also gave a scathing review of the new 640i GranCoupe. Now MotorTrend joins the fray picking the Audi S4 over the new 335i. The Audi significantly outperforms the 335i running 12's in the 1/4 mile stock with a 12.9@108.7. The 335i runs a 13.5@103.9. When is the last time BMW's direct competitor for an Audi model lagged this far behind? We all grew accustomed over the past couple decades to it being the reverse. ...

      BMW's dominance at the International Engine of the Year awards continues. No real surprise considering BMW is the most awarded manufacturer in the history of the competition now with 59 awards making for more than double that of the second place. The BMW S65 V8 wins its fifth straight award and likely its last with the M3 soon to end production. What makes this victory impressive is that the motor beat out the McLaren MP4-12 3.8 liter V8 as well as the new Porsche 3.8 liter direct injenction flat-6 in the new 991 Carrera S. ...

      The BMW 1M in stock form is a slower car than either the Panamera Turbo or the C63 AMG. When tuned however that changes a bit when the N54 twin turbo motor is opened up. The 1M here features an Evolve-R Stage 3 race tune with full bolt on's which include downpipes and exhaust. Evolve states the car puts out 440 horsepower on their dyno dynamics which is likely conservative considering how it handles the C63 AMG and Panamera Turbo. Video of the races below. ...
