Cold day and running 130 MPH this does not equal 755HP
If so Bob's and Kevin's LT5 ZR-1's must have 850hp both run 135+MPH.
WTH!!!
Can somebody please explain this.

I would've love to see his timeslip.

Somebody tell me where a kid like this gets the money to go out and beat on a brand new $130,000 car.

Looks like driver issues. he said he had a 2.3 60' time, his reaction time in the first one was terrible as you can see from the light. So my guess is he broke traction mid track or something like that.

That first run he was out of the throttle before he was through the mph trap. Appears to have shut down before the finish line.


All else equal, the mph would increase with some more miles. These arent the lightest Vettes either. That orange #4 ZR1 did dyno at 688rwhp.


A 2016 ZO6 has run a 10.0@132.7mph (Road & Track)with ONLY 650hp/650lb/ft torque.


I am seeing reports of 10.12@ 135 for stock 2019 ZR1's.

Ahhhh....... that is Street speeds channel. I've been watching his Youtube Vids for a few years now. He now has TWO brand new ZR1s, one manual the other automatic. He also has a 750 McLaren......He makes all his money from his Youtube channel. He seems like a nice guy, but comes across as annoying and arrogant.

How he got the 1st manual Z offered is beyond me, I'd say because of the popularity of his channel. He keeps saying he will buy the mid engine Corvette when it come out. And I bet he will have one of the 1st ones offered for public sale.

This is how he gets his money and how he has time to play on youtube.

I said the same exact thing..He also owns a home and a brand new McLaren....Did a little research on him....He actually has over 700,000 subscribers for his you tube handle street speed 717.....

From what I hear he makes 12,000 a month from you tube alone....I would guess that figure is a little high.Its probably close to ten grand a month ..

He works for a small brokerage firm and I would guess his salary is maybe about 40-50 K from that..He also invests on his own....

He actually is well spoken and really has made a name for himself with his you tube videos....

Today's CF article shows this as well. 2019 ZR1 stock with drag radials. https://www.corvetteforum.com/articles/whats-up-in-the-forums-2019-corvette-zr1-runs-a-10-12-quarter-mile/

Very nice, look at that 60ft.

The 8 speed auto allows for drama free launches. 1.58 60ft, stock torque converter, and the stock (auto) 2.41 rear gear and it's 1st gear ratio of 4.56:1 ,
2nd 2.97
3rd 2.08
4th 1.69
5th 1.27
6th 1.00
7th 0.85
8th 0.65
As we saw, the auto equipped '19 ZR1 was decently into 5th gear as it trapped.

The manual 7 (TR6070) speed gets the 3.42:1 rear gear and if the Z06 and ZR1 share the same TR-6070 trans ratios, it will have a 2.97:1 1st gear
2nd 1.61,
3rd 1.21
4th 1.00
5th 0.82
6th 0.68
7th 0.45

You are correct, both Z’s use the same manual, but the ZR-1 has s torque reduction to protect the 1st 3 gears. The auto is likely faster.

What's exactly torque reduction? Crazy.....Soon there will be no more manuals....

It is so you don’t have a drivetrain failure.

There aren't many GM vehicles built since 1992-93 with the advent of the 4l60e transmission that don't have some sort or torque reduction or torque management. It was usually reserved for automatic transmission equipped vehicles. Many would drop engine timing advance during upshifts.


I wonder how the application of torque through a clutch as in the manual differs compared to the application of torque through a torque converter as in the auto trans vehicles?
Are the manual cars more apt to have the front end swap positions with the rearend?


Torque reductions is mentioned as part of the many nanny controls of the new Z.


Active handling stability control with traction control


Automatically helps enhance control, particularly during emergency maneuvers, by adjusting the brakes and engine torque to keep you on your intended path
Activates when vehicle sensors detect a difference between the driver's intended path and the direction the vehicle is actually travelling
Includes Traction Control that detects wheel slippage and applies brake pressure and/or reduces engine power to help the driver maintain control when accelerating on wet or snow-covered roads
Traction control, all-speed Performance Traction Management

Available in the Track mode of the cockpit-mounted Driver Mode Selector
Offers 5 settings of torque reduction and brake intervention for enhanced track driving performance
May require additional optional equipment

There is a “ kind of predictive algorithm found in the dual clutch (automatics) to prepare for the next likely shift,” Alex MacDonald, Chevrolet’s Vehicle Performance ma manager.

Perhaps some day GM will use the dual clutch trans in the Corvette. Maybe the C8? Until then its the 8 speed 8L90 that the Vette uses, or the 10 speed 10L90 that Cadillac, GM fullsize SUVs and the ZL1 Camaro now use.


The GMC Granite prototype did use a 6 speed dry dual clutch trans.
