What does this have to do with the C8?

Wonder why the torque is so much lower than HP.

Expect it will be a target horsepower for the C8 when it goes to a DOHC Twin Turbo or supercharged V8 DCT in the performance versions.

When i saw the title of this thread it was a bit confusing, i thought you were making some sort of bold prediction about the upcoming C8 motor. Silly me

Nothing. Thread will be moved to "Other Cars" where it belongs.

HP is just a calculation... the higher the RPM the more HP you will have relative to Torque. Just like my e90 M3... 414HP but only 295 lb./ft of torque. Revs to 8400 RPM from the factory. The GT500 has less of a disparity because it only revs to 7500

The C8 is benchmarked against a Mustang? What a letdown.

It is more than just a calculation, It is also how an engine is designed. The HP and torque shown are peak numbers.

Take the LS7 and the LT1.


The LS7 has a peak torque of 475 lb-ft at 4,800 RPM and a peak HP of 505 at 6,200.

The LT1 has a peak torque of 465 lb-ft at 4,600 RPM and a peak HP of 460 at 6,000.

So what happened to the missing 45 HP that the LS7 has over the LT1?

The LS7 has 10 more lb-ft of torque yet has 45 more horsepower.

Is it a miscalculation or is the LS7 designed to breathe better after it's peak torque is reached at 4,800 RPM but it's torque is higher at 6,200 RPM than the LT's torque at 6,200 RPM, thus the calculation is correct and it has more horsepower?

relatively small displacement so have to spin it higher
HP = Tq*RPM/5252
smaller Tq means RPM must be higher.

You guys forgot about the massive Supercharger and the fact that the car is a piggie at 4,200 lbs.

Source for the curb weight? I work for Ford, so I'm curious as to your point of reference. A GT 350 comes in around 3650-3,700, figure maybe 200~250 lbs more for the blower and bigger coolers.
I'm currently a Corvette owner, and C8 buyer, but I did thoroughly enjoy my '16 GT 350 for the time I had it.

Do you have an inside source as to what the weight of a 2020 GT500 will be? There are 2 versions of the car the base version and the CFTP version. Over on SVTPMB we are wondering what the weight of this car will be.

Why. Thats about 146BHP per liter if the Corvette stays a 6.2 it would generate over 900BHP. Maybe thats what is breaking frames that we heard about.

My guess is the lower torque (625 ft/lbs isnít exactly low) is because of limitations on the Tremec DCT, which is 664ft/lb of torque, but also because the motor is only 5.2L of displacement.
The base GT350 comes in around 3750lbs so I could easily see the new GT500 in the 4100lb range. 2650 supercharger, intercooler, other coolers, and larger wheels and tires could easily make up 300lbs in this car.
The carbon fiber version with exposed CF wheels may be in the 4000lb range.
Just assumptions from the added components but seems reasonable.
My guess is the DCT will be a game changer and will pilot this car into the low 10ís in the 1/4 and make it very formidable on a race track.
