I got a little curious the other day and figured i'd compare one of my current 0-100 log times to 0-100 time of my best 1/4 mile run of 13.4@103. I was a little surprised by the results. I'm showing the current 0-100 time as 9/10th's quicker. :o Logs attached.
i know the resolution on the X4 is extremely high . . so reason should have it that 0-60/0-100 times should be pretty darn accurate right?
Both logs are 91 octane(the 1/4mile log had some 100octane added so if anything it should have the advantage)
Really the only "mod" that's been done is i've added the wastegate boost regulator and throttle now stays open during upshifts. Other than that there's been some tuning revisions but nothing drastic. Maybe an additional 1-2* timing. Boost levels the same and i've also learned to launch the car quite a bit better.
0-60 time on the 1/4 log was 5.078 and current log is 4.821
0-100 time on the 1/4 mile time was 12.6 and current log is 11.714
Car does feel faster and all changes were made one at a time little by little so maybe it's picked up more power than i initially felt but it takes a lot to drop even a few tenths in the 1/4 mile much less a full second. so i'm trying to make sense of these times on the logs before i get my hopes up too much. Maybe i'm overlooking something critical and shouldn't be taking them at face value.
Current 0-100 log was done on a flat strip of road and tires/wheels are the same minus a little tread wear.
And FYI the DA at the time of the 1/4 pass was 6200ft if any of these times seem slow to you.
Curious what other's 0-60/0-100 times are also.
I was reading on the ST forums that keeping the throttle open had a pretty positive result on the dyno.
IIRC it was like 30HP
I was mistaken, it was a few HP but about 20 WTQ...

This is funny, I just did this yesterday.. on my fastest 12.4 run 93 octane e20 tune I had a 4.4 0-60..didn't look at 0-100

Correct, I posted a link to that somewhere... it wasn't additional peak, but under the curve was improved.
There are pros and cons to having the throttle control torque output... in autocross using the throttle to curb output has shown the ability to prespool the turbo...
I believe the consensus is that for a straight 1/4 mile run, the ability to leave the throttle open has shown improvements.
I have also read that the TB is designed bigger to accommodate using it to control airflow for demanded torque..
In any event, Torrie only uses open throttle, LMS utilizes the throttle to control output, and AJP does both...
To the OP, I use the SCTx4 for 0-N calculations as well, I find it more accurate to open the CSV file in excel to do the math.. as livelink is not 100%.

Best I was able to get was 4.0 0-60 using the SCT output... and I was spinning in first... that was with AJP...
4.1 with LMS...

It's a good mod, but it does put more stress on the turbos as they are fighting a self created boost leak... I have run it both ways... I like the responsiveness of the throttle open...
I enjoy the fail safe and cooler IATs of the throttle controlled..
Wish there was a away to have both on demand!!!

As in open in excel and use the Time(sec) column for calculations? That is what i did to get the stated times.
Yup, I copy over the column with the time stamps next to the mph...

Thanks for the clarity check. Also, would you mind posting some of your 0-60 logs? curious to see others. Nobody ever posts logs of a dig pull.
Yea let find them... the 4.0 times and 4.1 where brake boosting... launch around 1800rpms..
With AJP tunes I get a ton of wheel spin and then I spin on the 1st to 2nd shift... at a track with treatment I am thinking I should be able to pull a sub 4.0 0-60...

That's another reason i would like to see others logs of brake boosting. I don't know if it's another effect of my altitude or it's something particular to my car but i have to brake boost from 2300-2500rpm to get this thing to feel strong off the line and even then i rarely get wheel spin. In fact in the latest revision Brad commanded more torque converter slip so it would be easier for the brakes to hold the car back at higher rpm.

Air is thin a mile or more above sea level.... 100% the reason...

I would say you're right but the couple other locals ive talked to don't seem to have the same experience and report the best results launching around 1900-2000rpm.

here's my last trip to the strip.I got there late so I just hot lapped it. Think I can get a little quicker with more boost on launch as there was just a little chirp on the second one.
12.93 run 1
12.88 run 2

Here is a dig with my latest tune.. still a work in progress but we are getting to where I want to be... might need meth... this was a 4.1 second 0-60 pull... I started getting some KR towards the end which was weird but then again I was running over a bunch of dirt at the point bouncing me around... dunno if that set off the KR...

Some I have, but not brake boosting normally nets the same number... spins too much... right now my car is up around 26 degrees timing on e30 and 14psi... it has been throwing traction control light on 1st-2nd shift

Hahaha no, not down hill... as flat as I can get..
I brake boost, launch around 2K... good tires though.. dunno... I've been racing for years... maybe 1000's of launches which equates to lots of practice? Dunno.. maybe I have a freak car? My strategy is different enough lol...
Should probably take this car to the track this year...

I've been racing for about 20 years, I think it has more to do with tires and pressure, I air down at the track. What tune u running right now? My 4.4 was a 12.4 1/4 mile

That's pretty quick!! Right now it's an E20 tune... datalog has all the goodies as far as boost, etc..
Tires are sport comp 2 summer performance... once temps get into the 30's they suck bad.. once warmed up they hook great...
That 4.1 was with tires at 35psi... no joking...
Here is another datalog... its a 4.2 0 - 60 with LMS 4+x race tune... its a good solid tune as well.. no E blending..
I just tried to do a 2k launch spun like crazy and missed 2nd gear.... no love... lol

Lol, might be too cold outside? My best times are when ambient temps are between 60-75... after the wheels have warmed up a bit...
The LMS run at 4.2 was a bit cold outside.. the denser air helped because honestly, I have not been able to get that low on LMS's tune but a couple times...
Brads tune I am able to replicate 4.1 often.. pretty consistent..
When I ran the wastegate mod I was getting 4.3 just by standing on it.. no power braking... if I tried to power brake I would spin too much.. never dialed in the launches with it....
Either way, I'm sure you are right there.

I think it was mid 20's outside... after this episode I think the car was in fwd limp mode after this ridiculous spinning episode. In fwd this car is useless... lol
