Have filed suit against Raza Khalid / RK. He had till last Friday to respond. Have 6 other people joining with more suits due to fault/fraudulent engine builds. Guy has even swapped blocks from a M5 to a 550i block on someone..
Avoid him. BTW 1000hp vs 600hp isnt a .3 improvement.
Here's the full story with Raza trying to defend himself and then fully being caught lying multiple times. Refusing to help with BOTH my cars he did and came out not running.
Saying my car ran a 4.63 60-130 reliably then I showed my text ( on the forum link below) from him admitting it made 1/11 runs properly and had total drivetrain failures every other time and broke up.
Sad there's so many scammers in the industry. So many people have come out of the woodwork with horror stories.

See the whole story above. There is a reason he only takes wire transfers. |
I am curious as to what causes the drivetrain errors on these builds. Did you by chance read any codes when it goes into limp mode (misfires, lean/rich, boost issues)?
On other models, BMW has an asinine system that disconnects the alternator at full throttle to save a whopping 4 horsepower.... To bad it drops your voltage from 14.7 to 11ish after being at full throttle for a bit. 3 volts on the battery is equal about 9000 volts on the spark plugs, greatly increasing the chances for misfires at high boost on tuned engines.
Again not sure if the F90 has this same issue as other models and its probably a much more complex issue with the drive train errors then something so simple as low voltage BUT why not eliminate the easiest variables first plus its so easy to test: Turn your blower to full speed and make a run and floor it right to the kickdown switch but not completely. Turning on your Blower to its highest setting on previous gens will increase voltage as it overrides the "intelligent" battery system so the alternator is engaged all the time and not just in coasting or braking or when the voltage drops below 11.
TLDR Version: Turn your blower to highest setting, floor it but don't hit the kickdown switch. See if it effects limp mode
