Ok, so I seem to have the same problem with my ACR that I have with my Le Mans. My ACR usually gets like a 9.036-7, but I ran a 9.020 and then a 9.008, and I have no clue where I shifted. Can I maybe send it to someone so they can see if my tune is maybe just messed up or if they can figure out where to shift it. (I usually shift right at the redline)
 
Shirt a little after 7000 rpm.
So In-between 7k and red line. One of my tunes shirt points are there. But my other tune that I have the top speed set to 185, It likes it's exactly at 7000 rpm. Try both see which one works the fastest for you. But it's go sure not less then 7000k

Is that from redline launch? or the launch trick?

thats a decent time for redline. youd be running 9.00's

It is the redline launch. I have no clue what the launch trick is, I don't need to know, but does it make the time faster and by how much? Thanks.

How's your suspension ? Toe, ride height ?

Oh, sorry Mikey I did not see your post, my camber is 4.5 in front 0 in rear, toe is -1 in front and .9 in back, and I am pretty sure that my ride height is minimum/maximum (that helps eliminate wheelspin right?). I'm remembering this from my head as I am not currently playing right now, but I think that's right.

Its pretty simple. Its mashing the gas button right before the countdown ends so you are launching at a better RPM, where you make more torque

doing this will shave off .03 to .04 from the viper. most cars it averages about .05 but some cars it doesnt help at all, or very little.

(redline launches can vary, thats how you ran a 9.008)

and then there are some other launches that are even more beneficial. but I digress

A fully properly tuned viper will be running 9.0teens to 9.0lowtwenties from a redline launch, so Like I said before, your time is decent.

to answer your original question, I shift at 6900-7000 with a 185 top speed

EDIT: Hey raise your front ride height to +40, and lower your rear toe to .75 or .65
you will be on track this way 👍

So it is better to not do a black screen launch, and wait right before the countdown starts? And that 185 top speed, is the one from the top corner of the transmission settings screen? And how is my suspension?

EDIT: So min/max would not help with wheelspin? I'll lower my rear toe.
EDIT: Sorry, I'm confused what do you mean by mashing the gas right before the countdown ends. And would this apply to online dragging.
 
I personally make a car as fast as I can with the black screen launches, and then I switch to the set RPM launch just to test. but I tune for indy and set rpm launches are not ideal for indy

and yes, top right corner transmission says 185

and i edited my post, I put some suspension advice in there
 
Ok thanks. So, you mean that you don't click any button before the launch on SSRX until right before the countdown ends? And is the best way to launch a car online to just hold the e-brake and gas at the same time until ghost?

When you go to Indy, set it back to -20. but most FR cars get a big boost at SSRX with max front

When the countdown is going 3, 2, 1 ... right before GO just hit the gas. its really self explanatory, just try it out for yourself, and no it doesnt apply online at all, since you have no idea when the ghost will ghost. yes just ebrake and gas

Is this because when you launch at SSRX the tires are not warm? Because with my nissan skyline nur I have some minimal wheelspin during my launch at SSRX, but when I launch at Indy with warm tires I tend to get more wheelspin, I don't know why.

Its because online physics are much different. You get much worse traction online at Indy

Also, the "1/4" at Indy is a little shorter than a true 1/4 so keep that in mind when you tune
 
Yeah I hear that the Indy is like 30 meters short, and so my tunes that I did with SSRX won't always be as good on Indy?

EDIT: I know that the Indy Road Course is the most popular, but are there any other tracks that you can drag on other than Indy and SSRX. They also don't have to be exactly 400 meters.

We are talking about an *almost* negligible difference

But let me give you an example. I have a Superbird with 2 transmission tunes. At ssrx the first transmission tune stays a bumper ahead until right before the finish line. the 2nd transmission tune is slower the entire 1/4 but .004 faster right before the finish line. So when I go to indy, I use the first one

As for other tracks, there is Fuji which has a true 1/4. but nobody drags there. Indy is the place to go.

Yeah I was thinking about this while dragging today and I realized that a AWD with a great launch but no pull on Indy, will beat a FR or MR car with a bad launch but great pull. Because the FR or MR car will not be able to get all of its pull, because at the shadow it would still be pulling. Saying that these cars have the same amount of horsepower, torque, and weight on SSRX these cars would tie.

Effectively yes, but to be honest, whoever has the better reaction time is going to win, thats more important than anything

Then why don't people drag there? Wouldn't it be much better???
 
Whever I time a launch I mash the gas when the "3" starts fade and hope I get a good launch
 
Street Racer
I don't see a post by you saying that Fuji is the alternative???

As for Fuji, indy just became 'the place'

keep in mind, SSRX hasnt been out very long at all. back in the day you tuned your car at indy, it didnt matter the difference in length
