Just finished racing at the GLC last weekend, The motor performed flawlessly
Super fast campletely stock shelf bought motor. This motor guided me to a 6th place A-Main.....I have already put about two gallons thru it and it is still very tight....incredible.
They were also clocking cars down the straight at one time and I was told this motor pushed my car to 62.7 mph second fastest among tourings....and this motor is stock.
