BMW makes most of its money on SUV's and these two essentially print money. The new F95 X5M and F96 X6M are expected to again dominate the segment and despite having less power (on paper) than the Jeep Trackhawk BimmerBoost expects the new X5M to be the performance champ. ...Published on 03-25-2019 09:02 PM
This video has a clickbait title as there is nothing stunning about an F90 M5 beating a Lamborghini Huracan in a drag race. Frankly, what is stunning is how much output Lamborghini is getting out of the naturally aspirated V10 and how high they are revving it. ...Published on 03-25-2019 07:22 PM
That ~800 whp range is nothing new for the N54 but truthfully if you want it last anywhere other than the dyno, you should probably build the motor. That includes a closed deck block to prevent the cylinders from getting out of shape which this 335i has courtesy of Motiv Motorsport. ...Published on 03-24-2019 05:52 PM
Is anyone really still worried about B58 tuning potential? The engine is hitting milestone after milestone in the aftermarket in quick succession. The latest barrier broken by a tuned B58 was the 700 rear wheel horsepower mark. ...Published on 03-24-2019 05:31 PM
There is a reason car companies spend big money on exotic materials in order to reduce weight. Ford includes carbon fiber wheels on the Mustang GT350R because reducing rotational mass has quite an effect on performance. ...Published on 03-23-2019 03:55 PM
Ever see the torque curve of the BMW N55 on the factory turbo? It's ugly. You can view a graph below but it makes you wonder what BMW was even thinking. It seems they overcompensated for the propensity of tuned N54's by neutering the N55 to way too large of a degree. ...Published on 03-22-2019 10:03 PM
This video really can be summed up in one screen grab but the guy sure loves to hear himself talk. The car you are familiar with as it is the ES750RS Porsche 991.1 Turbo S recently written about which has factory GT2 RS VTG turbochargers. ...Published on 03-22-2019 06:32 PM
Remember a post from last year describing valve float issues high powered S55's run into? Remember HeadGames taking on the problem and finding a solution? Well, the parts they developed are now available to order with pricing and information below. ...Published on 03-22-2019 05:17 PM
This E92 335i is particularly impressive when you consider it is a 6-speed manual. The owner has to row his own gears while the F90 M5 he goes up against has the computer do all the work for him. It also means the F90 M5 is shifting gears much more quickly. ...Published on 03-22-2019 04:42 PM
Wiseco has a Boostline product line of connecting rods which are said to be much, much stronger than traditional designs. What makes these rods different? They have a 3-pocket design that is said to be 60% stronger than traditional H-Beam rod designs. ...Published on 03-21-2019 10:43 PM
The back and forth on the S55 platform regarding the output world record sure is fun for BimmerBoost to watch. It was just earlier this month that Kratos hit 1150.3 rear wheel horsepower which topped RK-Tunes who formerly held the record at 1087.9. ...Published on 03-21-2019 03:31 PM
This Mercedes-AMG GLC63 built by GAD Motors is a stout performer. It better be considering it has the works from tuner GAD including a built motor, built transmission, and M177 turbo upgrade. Output is stated to be around 950 horsepower. ...Published on 03-21-2019 03:06 PM
More S55 tuning results with the EcuTek software suite are being published and Snail Performance did a custom Stage 1 tune on this F80 M3 Competition. This tune was done on a stock car on 91 octane pump fuel with no other changes but the tune. ...Published on 03-21-2019 02:16 PM
The next generation BMW 1-Series and 2-Series will share a Mini inspired FWD architecture. What does this mean? It means four-cylinder power and it also means do not expect another M2 with BMW M inline-6 power. ...Published on 03-20-2019 11:32 PM
You all likely remember the name @Sendit_e90 as his E90 335i set the N54 stock turbo 1/4 mile record earlier this year. Since then he updated his 335i with a new build including a single turbo conversion and a built 6HP21 automatic transmission. ...
