So about those chassis dyno numbers. HAHAHAHAHAHA GM guys wanted to believe so HARD!







At least they followed up with Vbox data and came up with numbers that are more realistic. They post on that part.

MotorTrend said:
Horsepower at the wheels came out at roughly 395 hp at 6,250 rpm with torque at just under 350 lb-ft at about 4,300 rpm. Assuming our 15 percent crankshaft-to-wheels parasitic loss figure, this car comes in a shade under the rated output at 465 hp and 412 lb-ft.



Those numbers are not shocking as they in line with what GM rates the motor at. As well as the weight and trap speed in the 1/4 mile testing people had done.

I don't think anybody believed those numbers, nor wanted to.

I didn't go back to look, but didn't you say right around 425??
Sadly not, VBox data is saying around 395whp. That to me is too low. But it could also be the exact same issues as the too high reading before. Some variable not set correctly skewing the results.

My friend was all over those inflated numbers. Going on an on about how the LT2 is the immaculate conception with an LS1 as the mother.

I never believed the numbers. They were a statistical anomaly.

And in today's WTF news. No way this think makes 600+ bhp or even 565. I can buy it makes a bit over 500 but come on...


Also I read the comments about under steer. Apparently Harlan Charles has already said GM will provide alignment specs for racing to eliminate the under steer.
At 3650 it would need a 500+. I think it makes more than 495 but not 565. Maybe 515-525.

Wat?
