Thought you'd all get a kick out of this...

 

Demon driver asleep

 

Sure...but that had zero effect on the outcome.

 

Looks like the SVR driver held the car on the brake with some RPM dialled in, something I have not tried so far, I just launch from idle.

Maybe I can go faster if I dial in some engine RPM with brake still applied?

 

Unless the Demon driver is a newbie, the Demon will "take it" UNTIL you have to turn the steering wheel (e.g. road track or simply a twisty mountain road) and then the F-Type would run away from it.

PS - The SVR driver also got away with a shallow stage so that he could roll some without tripping the light. Better Jag driver and the Demone would have lost by more

 

How do you figure? It's the reason he lost.

 

The reaction time is not included in the qtr mile time...they're separate recorded times as I understand. I believe its explained in the video.

 

When stock, it will launch a bit harder by brake torquing. However after the VAP tune, I ran quicker launching from idle. Otherwise it would trigger torque limitation and fall on its face after launch.

 

Gotcha

 

Kind of relevant - what sounds better out of the R and the SVR? Does the SVR actually have the supercharger whine that you hear in (say) the project 8 or the f Pace SVR promotional videos?

 

I would guess that the SVR has a little more SC whine than the R for one reason only - the SVR doesn't have an engine cover but the R does.
On my measly V6S the larger lower pulley and tune has made a huge difference to SC whine, I now have lots where before I had almost none.
Apparently the reason for this is that the VAP "with pulley" tune includes a tweak to the programming of the SC bypass valve so that it stays more closed (up to fully closed) earlier and longer.
Now the SVR might have a similar tweak in it's stock tune but I doubt it.
Point is, I put the engine cover back on two days ago as it's GoT "winter is coming" time here in South Oz, and straight away the SC whine dropped by maybe 40%. I will be taking it off again real soon!

 

There's pretty much no audible whine in mine with the stock intake and pulleys.

 

 

 

That is ONLY for the v6 models and possibly only for the S. It does not work on the v8s.

As far as SC whine, my R DEFINITELY has a nice SC whine once you get over 4,500 & are still pounding it.

 

That depends on what you call "winning". The reaction time will DEFINITELY play a factor in who crosses the line first and THAT is what real drag racing is about.

The lowest Reaction Time (RT) paired with the lowest Elapsed Time (ET) = The FIRST car across the line and that is the WINNER on each and every NHRA race so while some may say that RT doesn't matter but those same people aren't actually racing "heads up" in that case.

 

OK something I need to try, I asked on the video and they replied they found around 1400rpm was the best launch RPM.

Did you find similar when stock?

 

I didn't experiment with varying the launch RPM. It was either WOT off idle or full stall of the torque convertor.

All this talk about 1/4-mile times is giving me the itch to go again this evening. I have yet to run the car since fitting the VAP catted downpipes, but they should be good at least 1-2 MPH combined with cooler temps. Wishing I didn't fill the tank Monday...

 

You should go, just drive there fast, use up more fuel.

What is a full stall of the torque convertor?

 

Went 11.41 @ 124.2, a new PB in this car for both E.T. and MPH. All runs were with about 3/4-tank of 91-octane, same launch procedure (WOT off idle), with traction control fully defeated and the transmission in S letting it shift itself. Only mods to the car are PS4 tires, VAP tune, and VAP 200-cell catted downpipes.

Runs 1, 3, and 4 were in snow/ice mode per Gibbo205's experience. Run 2 was in dynamic, which happened to be the slowest pass. Go figure.

Temperatures were in the high-60s for the first two runs dropping into the low-60s for the last two, but with a very annoying 17-18 MPH direct headwind. Also, the first run was with the car completely heat-soaked. If anyone's familiar with Sonoma Raceway, you know that traffic the last 2 miles of highway leading to it are spent with your foot overing over the brake, and I staged for the first pass within minutes of entering the gate.

For comparison, I ran with gentleman in a stock 2016 F-Type R (Car #70) who goes to the track 2-3 times a month in runs 2 and 4.
