@Tonkabob any plans for primary / secondary downpipes on your car?

Probabaly not. I don't want the car louder and want to run a street legal 11 second 1/4 mile.

Looks like it's time to delete the headrests, remove loose change, empty windshield washer fluid, take a big dump (or find a skinny driver (wife perhaps!?)), and shoot for the stars.

 

[TwinSnails]

I personally don’t live in CA, and those secondary cats can just fall off!

 

[Terry@BMS]

Prediction comes true.
New AWD record. Still have cats and muffler. 11's so close!

First of all congrats on the time.

Technically, this slip should be invalid because the maximum slope exceeds 1%. You see it going up hill and then down hill at least 3% at the end inflating the trap. There is a bug in the app that allows it because it's only checking at the start and end point right now, it has to check for any deviation of 1% or more during the run. That will be fixed in the future. You'll want to find a straighter road for it IMHO to see what it really runs. ET should be close, trap will be slower of course.

I noticed that, thanks for explaining the way it validated. Do you guys offer a LEO/Military Discount on the JB4?

Tonka congrats man....but i need to see the time at the strip...that is what counts on my eyes...

So you are saying its faster to drive up hill so you can drive back down. The slope is .8% from start after a .5% rise which slows you down. (Not 3%, and dragy has no limits on up slope) It certainly would be faster to skip the .5% rise and then do the .8% or 1% fall.
We are talking a 6 foot rise and 10 foot fall over 1320 feet. Dragy allows a 13.2 foot fall with no rise and still valid.
This 12.06 is net flat with a hill. Certainly no advantage over flat and much slower than the dragy allowed 13 foot drop.
And still the AWD record if dragy is accurate.

Sir I wont get to the technical.....when you hit the 1/4 mile strip And show the slip or a video then we are talking.....Tork didn't use Draggy on their run, they went to the strip and for that I respect Tork that is the way you are suppose to do it....

Just explaining that the slip should be invalid due to the slope variation I see in the chart. It's a known bug in the dragy software that it was marked as valid. At the end of the day who really cares, just letting you know so you're not surprised when you go to a track and the trap speeds don't match up.

Read your post again, seems you didn't see what I was referring too. Note the last "quarter" of the run. 330' distance, slope of -13', which is a -3.9% grade. A grade anywhere in the run of more than -1% makes the run invalid.

Fastest 0-60 and 1/4 mile for me, therefore quite happy. Now if I could only get my 60ft less than 2. That’s only happened for me once.

Car: GT2, RWD, 7800 miles
Oil temp: bordering on 200

Mods: RC GTS Black - Map 7, RC XLR in Race+ (doesn’t increase HP), and HKS plugs

Octane: ~98, 1/8 tank
Removed: spare tire and head rests.

Temp: 63
Altitude: Sea level

This Run was with AH, stability and Traction control enabled and RC XLR in Race+, not sure if the XLR setting helped or hindered me. I also tried with LC and my 60ft nor any other distances were faster than AH.

Since a lot of us don't know how Dragy calculates, do you know how trap speed is calculated? Is it an average speed over 66 feet like a dragstrip or an instantaneous snapshot of GPS speed when the 1/4 mile is over? Going downhill at the end of a run would definitely skew trap speed on Dragy if it was taking an average like a dragstrip does.

Previously, dragy was taking your speed at the very end so it ran a couple mph high. I think they fixed that to match the drags ave of last 60 but maybe someone can confirm.

I get your math now but if that was the intended calculation nearly every run would be invalid unless you were on a perfectly flat drag strip.
A 3 inch dip in the road in a 30 foot section would make your run invalid. (Maybe dragy will change it to 1% within a half or quarter of the run)
But do get your point on trap, and not advocating that all dragy runs are perfect. But still disagree its not a valid dragy run due to slope.
One advantage of dragy is control of car temps. No lines i can start my run with an 80 degree intake temp and cool intercooler rather than 130 degree intake. Can also pick your weather more easily and run in cooler temps.

I agree track is the way to go. Went there 5 times last season. Our tracks are closed and the community said dragy was the shit so we tried it.
Got a dragy cause people didnt think we could run a sub 4 sec. 0-60. Did it and people questioned it. Did it 3 or 4 times now, including a 1.87 60 foot.
And now get the fastest AWD three times, 12.08, 12.06, 12.03 and people question that. Seems like the rules keep changing.
(This slope is less than 8 inches )

I don't think anybody called BS on any of your times, only a comment that your trap speed may be off due to slope. Your car is very impressive and making us RWD guys a little jealous. Next year when I get lighter wheels and 285s I hope I can come close Maybe some Michelin Cup 2 tires?

How to implement the check is the current sticking point. If it's too restrictive then it will be difficult to find valid tracks. But as implemented the times are not accurate. A common "hack" for example is racing up a small hill for the start to improve traction then racing down a large slope to inflate the rest of the run while still winding up at less than -1% overall slope from start to finish.

One idea being thrown around is computing slope off the height min and height max achieved during the run. It doesn't fully solve the issue but helps mitigate it. Under that formula the run I was commenting on earlier would be around a -1.3% slope. The other alternative would be to take an average slope over some distance like 200' and if that ever drops below -1% invalidate the run.

Anyway clearly the cars have high 11 second potential so I'm not commenting on your performance just the obvious issue with the measuring especially trap speed, in this case. My private track has a similar issue. Here is a run I did last night in our 2018 C63. Depending on what formula is used it might also be invalid.

Average over last 60' like a track.

Good info. I have a flatter track in mind with about 15 min further drive. I don't need the up hill traction by any means.
Western Wa doesn't have many flat spots and tons of traffic.
