0-60 Times
 

I know 0-60 is typically a very noobish thing to talk about, but with datalogging vss its pretty easy to get and its at least legal-ish under the right circumstances. I figured I'd post and see if anyone else wanted to share their resuts.

First run was less than ideal, bogged, spun, I think I can do .5 better at least so I'll do another when the opportunity presents itself.

Time: 661.100-656.166= 4.934

​​​​​If anyone else feels like sharing post them up.

So, do you count launch as the lowest rpm in 1st?
I think I was close to 4.3-4.8 with a good 12 second pass.
My computer hasn't been on in a while, so I don't have a log to post, I got other priorities at the moment. Perhaps I can get under 4 seconds soon. I hope to come close to your ET and get ejected for no roll cage.
For the record, pdexta is one of my mentors, whether he knows or not. I will try to come up with some log pics soon.

Haha, thanks. I didn't really expect much interest in the thread, but figured I'd give it a shot. It anything it'll help me keep track of what times I'm getting.

I counted time from the last "0" mph reading to the first "60" mph reading. Obviously it can be screwed with to make it say anything but I think mine should be pretty accurate.

Finally got another chance today and got in a much better time. I'm hoping to get down into the 3's, but not sure if I can get there. It'd certainly help if I could get my boost controller working consistently.

892.845 - 888.375 = 4.470

For whatever reason I can't seem to log my VSS so I am basing it on 5100 rpm in 3rd. Which is my calcuated 60 mph speed???
It does look like you start between the 2 low rpm points after revving to launch. I think I counted between the last rev and 1st low rpm point.
Oh nevermind, I am gonna boot up my laptop.

Just went and looked at the most recent Pro Solo data I have. The car went 0 - 60 in 4.61 seconds.....But the slalom started 47.2mph. The car was pulling 1.36g turning left by 49.3mph and 1.47g turning right by 58.6mph. The 1-2 shift happened at 46.9mph and was on the initial turn in so it wasn't a fast shift.

Based off that information I am really curious what it would do 0-60 in just a straight line with no lazy shift. If just the shift on that run had been a "no lift shift" it would have taken .364 seconds off the 0-60 time.

I'm betting with dumping some rebound in the front and just going straight the car would go well under 4 seconds on A7s

This was a 12.8 @ 107 I think.

Niceeeee

Mid 4 second 0-60 through a slalom seems pretty impressive :bowrofl:

Niiice, man that's moving. I'm determined to get in the 3's now.

Made another pull this morning. I really need to find a nice calm place to do this instead of just random red lights on my drive to work.

I managed a 4.111 this morning

It does help to have a sanctioned drag strip. I would get in trouble launching like that on my way to work.
4.111 is almost there.
My little 5 speed 4.3 rear combo is really pretty stinkin' quick out the hole. Especially for my tires (also aired down a ton) many muscle cars with drag radials can only get a tenth on my 60' time. Also, they spray coca cola on the track or something to make it stickier, plus I try to go behind someone with zero treadwear tires.

What I am getting at is that my car is slower on the street. On the street I can usually hear my tires squealing through the top of 1st and 2nd gear. On the track, when I do it right anyway, the thing just hooks up and goes.

I will try some logs from stop lights when my car is working again.

What kind of 60' times were you getting at the track? I don't think I've ever gotten under 1.9 and I'm usually running 2.0s.

This is a pretty epic response. We can close this thread now...

I think this is my best 60' on the right, still looking though. I do consider anything under 2 seconds to be a good launch. I am usually right around 2, give or take a few hundredths.

For reference, we have gone 1.83 seconds to 60' on a virgin, unprepped surface while running 700lb/in rear springs :)

I'm all over those 1.9s and 2.0s. Wish I'd spent some time setting up launch control, I feel like it would have done better.

https://cimg1.ibsrv.net/gimg/www.mia...dfcbd6fb48.jpg

This is just INSANE!

This is the problem I had at a local track- zero prep, rocky as hell surface. I couldn't muster better than a 2.1 @60ft. but did eek out 8.0 @ 99 mph on the big end of the 1/8th mile.

Looking at PDEXTRA above- drag racing is strange.. you kill me at 60ft AND 1/8th, but my MPH was a bit higher and my time was slower. I know why, but its still strange kind of.

The more you spin the slower you run, the slower you run the higher you trap cause you have more time to build more speed.


On street tires or slicks?

On Hoosier A7s that actually launch worse than street tires due to the very stiff sidewall construction. (Not opinion, it's factual, been tested numerous times at drag strips all over the US.)

I'm sure they're not good at launching, but they're still night and day better than an all season

You don't say......Let's just compare 0-60 times with everyone on Goodyear D60A2s........who run's "All seasons" on a boosted Miata anyway? And if they do....they don't care about 0-60 times.

Probably depends on the surface. I spin "street tires" in 2nd at full boost, hoosiers don't spin. Hoosiers don't launch nearly as well though. They like to bounce and skip.

I run all seasons and those are my 60' times with them. 380 treadwear IIRC.

For the record all of the manual transmission drivers who achieve 1.7's or less at my local track do not use launch control. They also tend to win 1st place, I don't run launch control either. I know that my opinion is in contrast to the general consensus here though.

Launch control is nice because it allows you to build boost on the line. With 380tw tires that's useless because you will blow the tires off. With slicks it's a different story.

You can also do things like ramp in timing and boost after launch.

Yeah, I hear you.

I bet Pat has some good 0-60 logs and 60' times, his car pops wheelies.

I think it took me a month to read his build thread. I bet his 0-60 is killer.

Playing with FM's gear calculator, it looks like you can get to 60mph in 2nd gear in every stock 5 speed gearing setup. That shift to 3rd is definitely killing me.

Interesting, I used the calculator for 3rd, my logs do look like I have barely finished shifting at 5100. I didn't even consider 2nd.

Looks like I reach 60 MPH at 6650 RPM in 2nd.

2668.822-2665.627=3.195
This puts me insanely close to 3 seconds flat on a well prepped surface with low pressure in my all seasons, so I started a little earlier.

Last time I was at the track I ran a 1.68 60' time with a soft launch (8 psi on launch...) I need to work on my car and put the new diff in the car. It should be 60' in the 1.5's with the new diff, launching with more boost. I'd like to get it into a high 1.4, but that's a goal for after the car is in the 1.5's!

0-60mph times, probably low 3's. It's not a sub 3 second to 60mph car right now, but should be with the new diff and a harder launch.

I need to go work on my car....

Just checked my log from last night.

0-60 2.891 seconds

Dang, you got me beat big time. What tires are you running? What whp?

The best I've logged so far was a 4.188. Feeling pretty slow now.

I'm wondering if vteck logged wheelspin, 0-60 in 2.8s is really, really, really fast. I can't do that on radials with a trans brake.

Rs4s. I logged a tiny bit of spin going into 2nd but I didn't hit 60 until right at the limiter in 2nd. Pat I'm at 350 whp.

BTW that's from the log at the track. I can't come close on the street. Spins all the time.

Was this at a drag strip? What was your 60' time if so? What gears/trans/rev limter puts you at 60mph at the limter in 3rd? Did you launch in 2nd gear, or do two gear changes in that time frame?

Yes, I was at the strip. 1.7 60' and I launch in 1st gear. I shift to third gear right at 60 mph. 7400 rpm limiter with 6 speed/3.909 gear.

Thanks. What was your 1/8 mile ET and mph if you don't mind me asking? I ran a 1.68 60' last time in the 1/8th, 6.93 @ 103mph and I didn't think I'm below a 3.0 0-60 time.

7.492@95.74 mph. You're more than welcome to check my math, I can post the log. You are certainly lower than 3.0 sec.

Sure, post it up! I need to hook up VSS for datalogging on my car. I just assumed I'm in the low 3's.

Holy shit.

Here is my log.

I just had a peek at my 1.9 60' with 8.29 at 84.8 mph 1/8 from last Wednesday. I think my 0-60 was about 3.2 seconds. 5.41 330'.
I also don't have my VSS working.

am I allowed to play this game in my subaru? :giggle:

Of course, we want to see what we can beat around town.
Can I eat a badass Vlad-e-tuned rabus or not?
:skid:

If I can figure out how to get the Hydra to record 0-60 I'll post up. Is anyone using launch control for this?

I have not used it yet

Ignoring wheel spin, and starting the clock when the revs begin to drop (when you launched) I got a start time of 25.24, and an end time of 28.602, for a 0-60 of 3.362 seconds. That's how I calculate it anyways.

Pat wins :likecat:

anyways dug out my old slip
https://www.miataturbo.net/attachmen...ine=1439442529

according to bench racing calculator that's right at 3sec, I know I also have the log so I'll try to find it too.

a 350whp miata would definitely gimme a run for my money if on proper surface

In the video are you doing a 2nd gear pull or are you hitting 60 in first? Didn't seem like you shifted.

Impressive regardless!

I launched in first, shifted to second around 50mph, if you watch the tach you'll see and hear the RPMs drop a bit around 50mph. This trans/converter is designed for max acceleration, so the RPMs don't sag a lot on gear changes to keep the motor in the powerband.

Nice! Yeah, I couldn't even tell you shifted.

Why do the revs crash and then jump back up like that?

Good job Pat!

My tach is messing up, dunno why, it's super annoying. I need to look into that.

Thanks!

One of my runs was 4.0 to 100kph(62mph) and 11.3 to 200kph. With r888 tires and NO grip. With better traction it would probably be in the low 3sec range to 100kph.

Very quick! Good job!

I have measured 0-60 using the dragy gps device, performance expert app and older g-tech. I usually get somewhere in the mid 3 second range 0-60 on all three measuring tools. The dragy device uses accelerometer as well as high speed gps, plus its been tested by many people while at the drag strip and proven reliable, so that's the one I trust the most for my personal testing since the most local drag strip is over an hour away. One has to be careful when using speedometer or driveline sensor data as wheel spin will skew the results. The following pics are screen shots from one of my most recent dragy 1/8th mile tests. On the same run it recorded a 7.36 second at 102.76 mph in the 1/8th mile while reaching 0-60 in 3.50 seconds or 3.26 seconds factoring in a 1' rollout.
