Good runs. I didn't see that outcome either. If his car has 80 more hp and a ton more TQ why didn't it catch you?

As expected.

Anytime i hear some bufoon blurt out "Torque win races bleh bleh blah blah" i just laugh a little inside because they obviously dont know shit about drag racing and the relationship between torque and HP.

Great runs and beautiful R8.

Because torque means nothing and AWD equalized any advantage the HP of the z06 may have had.

LOL. Ok. But the Vette didn't look like it was spinning. And even if your theory about TQ is right, the vette still has 80hp on the Audi and should have made up ground.

Was the corvette an A8? Or M7?

Oh It’s not my theory. I could care less either way.... It’s a mathematical fact. Torque is a meaningless number in drag racing.

Have you ever been down a drag strip? Serious question.

A8 from what was said before. I’ve never heard of an intake adding 40-50 rwhp on a C7Z but it is what it is.

That's what the owner told me , seems like their website says the same thing
Halltech Stinger-RZ Intake for C7 Corvette Z06

Halltech's 2015-2019 Corvette C7 Z06 Stinger-RZ will put you in the winner's circle. 1/4 mile e.t. improvement= .41 seconds; 1/4 mile trap speed improvement=6 mph! Dyno tests have shown between 38 and 52 RWHP with no tuning.
Two recent dynos at A&A Corvette (91 Octane-A8s) reported 44 RWHP/41 lb-ft and 50 RWHP and 43 lb-ft with the stock ECM parameters, i.e. no tuning.

Why do cars run low gears then? Why do modern S/C cars all make over 600tq why do TVS blowers out perform whipples?

Maybe if you had a car that weighed 1000lbs. It absolutely matters to get off the line when new cars are 4000lbs

That is a bad BAD machine. I’m a fan.

Thanks

The A8 really wakes up with a tune. Too many safeguards built in from the factory. Watch some of RPM’s vids on YouTube after Fran tunes them.

Nice ride too OP. I love that color.

Thanks , I really love this color too

Yea, that color pops
Thanks

Beautiful color and it moves out! I didn't expect the Z06 to hold in so well on the launch.

Thanks , auto car on drag radials and prepped track

Looks like you pull the seat all the way forward.
it's not that bad , I'm not the biggest guy neither the smallest . 5'-10'' , 190lbs . Happy to be where I'm . Better then being overweight 300lb hamburger

Good runs. I didn't see that outcome either. If his car has 80 more hp and a ton more TQ why didn't it catch you?
Some cars run more efficient then the other . LT4 motors with the small blower aren't very efficient engines , the other is the DCT trans . Video clearly shows the the vette was falling behind during shifts , GM claim of their A8 shifts quicker then DCT was a bogus claim

Beautiful car OP and nice runs! Really have that itch for an R8!

Thanks , bad ass cars , love it . Drive it every chance I get.I put 3500 miles on the car in less then 4 months , more then my daily F150

I was just busting your balls Gofast, I had to when you had a matchy matchy blue polo. I dig the blue brakes.

And it looked like it was falling behind because you are holding the gear longer than the Vette.

R8 heaving 4500rpm LC and short gearing DCT helps alot . The car runs from 7000-8900rpms once it gets going so it doesn't need TQ , it stays in HP powerband

They lost me at 6mph trap speed gains. Either way that R8 is sick.

Yes, gearing is an important part of the equitation. Torque? Nope, 0, nada.

OP just proved it post 1 page 1, but the math has been saying that for decades. His car is 4500 lbs and makes under 500 tq.

Why do you think a 4000lb diesel drag truck that makes 900hp/2000tq runs the same time/trap as a 4000 lb mustang making 900hp/600tq?

Horsepower vs Torque - themusclecarguy.net

"A couple of things, the more torque an engine makes at any RPM, will also result in more horsepower at the same RPM. Also, the higher the RPM that a torque value occurs at, the higher the horsepower number.

In drag racing, as long as the gearing is correct, torque doesn’t matter, just horsepower. I know that sounds odd, but it is true."

Torque matters but not even close to the extent that people think. It’s all about horse power when it comes to racing.

The R8 was the more efficient car. The transmission and AWD were much more effective. Also a possibility that the vette could have been a little heat soaked. Although, the times OP is posting seem to be a bit faster than the average z06.

1. a R8 isn’t 4500lbs lol
2. If 2 mustangs had the same gear and weigh exactly the same but 1 makes 600hp and 400tq and the other makes 600hp and 500tq the latter would win. We see it all the time with TVS cars vs other blower cars.

For example,

My LSA in my SS rips the doors off my buddies SS with a D1 and he makes 100whp more. Different power band and more efficient with more low end to get going. We both run the same exact gear and tire.

If the R8 wasn’t awd it would lose to that same C7Z, but it has a way to overcome the lack of torque by, you guessed it artificially multiplying its tq with gear ratio and then using its higher rpm to stay in the power band after it gets moving, if he launches off at say, near idle like the Z probably did, he would have lost bad.

Just to prove the point a bit more. IF tq didn’t matter, why aren’t GT350’s dominating and the drag strip? 526 Hp should go way faster than mid 12/ low 12’s.

If tq didn’t matter why are long tube Coyotes faster than cat delete? More tq down low and more of it.

I’m not saying tq is the end all be all but, it sure does help.

What you’re really saying here is that you agree torque isn’t as important as some people claim, provided you make the most of what tq you have and stay in the hp power band.

Manual trans and crappy gearing for 1/4 mile is the main reason . I bet Gt350 with proper short gearing DCT and drag radials would be a mid 11s car
