How fast does a GT3 pull away from a GTS....

I understand what you are trying to say. Yes, the GT3 is pulling away from you at the straight, but that's expected from the power & weight different I assume. It seems it pulling away very well but no really out of the ordinary or expectation IMHO. Try to shoot it again with a Turbo/S in front next time (if you have a chance), and you'll think "man, that Turbo dusted me (on the straight)" and it'll make the GT3 looks "not slow" but doesn't pull away as hard from you.

Both off line all over the place? Not sure if you know that track well but I don't think so. If you mean when the gt3 went left for no reason sure...I've been going to that track ten years. Also the cones are NOT set exact. If you are watching the same video I am you'll see the cones in the esses are off and far in the dirt. The second or third one is way off! Turn one after the straight is set too early. I'm not a pro but have driven around it with many many people, have buddies who do the time attack competitions three and a friend who instructs with Porsche. Another who raced in the Peyton series. We know the track pretty well. If I'm still driving off the line after ten years then shoot me and I quit 😂
Maybe YouTube some of the record setting laps there if you're not familiar with the track.
It's really hard to post on here sometimes. I mean Jeez! I only share on here for fun and to share info or fun/learning experiences. Then people start saying negative **** or getting wild about it. TO ME - If the faster car was in back u wouldn't see the front car pull away like that, the gap would decrease even though the person ahead would appear faster at first due to them getting on throttle first. And the gap wouldn't increase as it does specifically in the straights which shows the power difference. Even more so you or someone else mentioned the GTS gained under braking so it's really all showing the gains in the straight then. But maybe I'm an idiot and have no idea what I'm saying.

Thanks. Glad it's acceptable 😂
Right! Wild! It can almost be worse than the young kids going nuts in be M3 forums. I just saw another thread in here where I guys made his SW vs GMG exhaust videos and people started talking **** for no damn reason. Why's everyone so god damn angry!

@ Buttonwillow...best lap times were 1.5 seconds apart, both stock.
Watch through the esses and then the main straight...he just pulls away fast on the straights! Its my friend in the GT3.
Edit: just posted it for the straights and esses to show how he pulls away under power. Not sure if he was driving to the max otherwise.

I have both. Gt3 much faster in a straight.

I agree that's what expected. That's why I posted it. Was just an example we don't see often.
Thanks. Glad it's acceptable 😂

If you're really trying to compare acceleration the bigger problem is the GT3 being in front always gets to start accelerating first, so will always look to be faster. In fact if you switched the cars around then the GT3 would see the GTS accelerate and pull away first, and it would look like the GTS was faster! Especially if the GTS driver takes a better line resulting in a faster exit speed, this could totally erase the GT3 advantage and you would be convinced the GTS is faster- when really its the driver.
Let's assume two identical cars, with one car ahead by one second at corner exit (30 MPH). That is equal to a distance of 44 feet. As you go down the straight, assume a maximum speed of 120 MPH. Assuming the same one second gap, the car in front will now be ahead by 176 feet. Under braking, the process is reversed, and the gap appears to close, but will remain at one second.

Great point. Here is the mathematical calculation that validates your point. When people talk about "I closed the gap under braking, and in the corners", it is true that you are minimizing the distance gap. But, you are not minimizing the time gap.
