Took the car to the track for the first time this past Friday, and have to admit, I was disappointed. Had a great time, but disappointed.
Here are the specs:

2016 F Type R AWD
Mina Gallery complete upper/lower intake
Mina Gallery lower pulley
VAP 200 cell downpipes
VAP stage 2 tune
91 Octane pump gas
77 degrees and 10% humidity

Ran back to back to back runs and then went home. I’m car 37. Here are the slips:



Seems to me this is what the car should run stock… am I wrong?

 

 

Another video attached.

 

Sounds epic!

I have very little clues about anything car related but I would mention that I was told to run mine on Aust 98 octane fuel post tune (about 94 of your US octanes). Your times are pretty much spot on for the "fastest lap" times https://fastestlaps.com/models/jaguar-f-type-r-awd

 

Fuel quality / octane has been brought up with an acquaintance of mine who has a modified R as well. Arizona has horrible fuel quality, so an octane booster, running a gallon of E85 in a tank, or methanol injection has been discussed. Poor fuel will pull timing, so maybe I’ll have to consider looking into it more seriously.

 

Cograts, you have very consistent times what times and trap speeds were you expecting?

I have read these cars are definitely knock limited when tuned. You also have the full metal Mina intake - if it gets heat soaked you can lose power and trigger knock.

Do some logging on your next runs and see if anything unusual is happening - knock, timing pull, ignition miss, fueling issues.

 

did your tires spin

 

Thanks. I was expecting 11.1 and really hoping for a 10.999

No tire spin. Freshly prepped track, first one on it, new Michelin tires, all wheel drive… plant and go.

 

Your 60-foot times look good. What was your launch technique? Did you launch from idle? I have seen my best results by launching at about 2000 rpm. That seems to load up the driveline and build a little boost before launch.

Your ET and Trap Speed seem off for your mods. What was the elevation or Density Altitude when you ran? The Temp and Humidity seem reasonable, but if you were at elevation (physically or due to barometric pressure), that will rob horsepower.

As previously mentioned, doing some logging would be wise to see if any timing is being pulled.

 

There are a lot of variables that impact quarter mile times. Driver experience, fuel quality, tire pressure, ambient air temperature, density altitude, TCU calibration, transmission strategy whether you are letting the car shift automatically or using paddles, even something like belt slip can all make a noticeable difference.

For reference, my personal best pass was a 10.98 in the winter months here in Florida. At the time the car was Stage 3 with a TCU tune, downpipes, and the stock air intake. Around that same period I was typically running between 11.11 and 11.43, with the quicker passes coming as I got more seat time at the track.

I did have to lower tire pressure to help with traction. Even if you do not feel obvious wheel spin, the 60 foot times usually tell the real story. Small adjustments there can make a big difference.

Running 91 octane and dealing with heat soak will also limit performance, especially during back to back passes. The all metal intake pipes from Mina Gallery tend to retain heat, which does not help in those conditions.

If you would like, we can take a look at some data logs and help pinpoint what the car is doing and where improvements can be made.

 

Certainly understandable to be underwhelmed. You’ve got the parts needed to run ~11.0 but your MPH came up short, so I assume you’re making less power than you should. How was the DA that day?

I would be interested to see how you did on race gas. These are my times on 93, with just a lower pulley, 1 step colder plugs and a VAP tune.

 

Launching was left foot brake once staged, load torque converter on middle bulb, full throttle and release brake on last bulb.

Those slips are what I was expecting. The 125/126 mph ET’s. I would have been very happy with those.

Data logging has been brought up numerous times, and makes the most sense. What are people using for hardware/software? VAP - DM me what is necessary from you all and I’ll look into it.

Next public track day is March 6, but temps are already starting to get pretty warm here in Arizona. I’m guessing we will be in the 90’s by the time that next date rolls around. No one is running decent times at those temps.

 

Here is the link to the data logger tool: Jaguar/Land Rover AJ133 & AJ126 2013-on Datalogging Software + Cable

 

Datalogging with a laptop at the drag strip can be a little tricky. My track requires me to have the laptop seat belted in the passenger seat to prevent it from flying around in case something happens. 😄

 

We can pull data logs from any drive, does not need to be a full 1/4 mile. Long enough runs for us to see what the car is doing with timing, knock, fuel, boost, etc.

 

Nothing tricky about it...

Laptop on the seat, pull the belt out all the way and buckle in, let it ratchet retract to hold the laptop tight and locked in place on seat.

It's how we all do it when datalogging on the strip or circuit track, nobody wants to ride copilot with a green face so that seat is often with a laptop to datalog.

 

I bought some adhesive heat reflective material off of Amazon and wrapped the parts of the intake that were metal using metal zip ties. Took the car for a spirited drive last night (high 50’s, low 60’s temps). The intake tubes were actually cool to the touch. Supercharger lid was noticeably cooler as well. Those intake tubes have never been cool to the touch before. I’m hopeful… Every little thing helps, right? Haha

I’ll be looking for other ways to cool things off, but in the meantime, I’m considering fuel options. I have a gas station a few miles away that sells E85. The E85 in AZ is closer to E54 according to one tuner I had tune a car for me a few years ago and internet searching. I’ve mixed E85 with our 91 to raise octane ratings in the past with my VW - any known issues that would cause with this platform? Looking to go from 91 to at least 93.

 

You would benefit from using a fuel ethanol content test kit, such as the Fuel-It Glass Ethanol Content Tester. Fuel-It! Glass Ethanol Content Tester

It does not have to be that exact unit, Amazon carries several similar options. The important part is being able to accurately measure the true ethanol percentage in the fuel before mixing.

There are also mobile apps available in the Apple App Store and Google Play Store that help calculate proper ethanol blending ratios. One iPhone app I have used in the past is e85Cal, which makes determining mix percentages straightforward. ‎e85Cal App - App Store

Most likely, you will not have any issues blending ethanol to raise octane levels when done properly. Alternatively, you can use a product like Boostane to improve fuel quality for track nights. That said, I would avoid relying on octane boosters regularly and reserve them for occasional use.

 

Thanks for the response. I ended up putting in 5 gallons of AZ e85 and filling the tank with 91 octane. So far so good, with zero issues. Car is running well and pulling hard when I get on the freeway. I won’t be doing this all the time, but wanted to test it out before going back to the track.

Not sure I’ll get back out on March 6th. Temps hit the 90’s this week, and I expect they’ll be at that mark in two weeks. If they are in the low 80’s that day, I may consider it.

 

Unfortunately it won't go any faster than that the ecu won't allow it is not knocking and there's nothing wron with your car what your are seeing is torque management doing it's job and believe it or not the more Modifications the slower it will go you need tuning that will remove torque management/torque limiters meaning you need to set torque limits higher. Only solution for now is to go with a jb4 which overrides torque management here's one of my jaguars running 10s @117 with a misfire letting off after the 1/8 the car is completely stock no pulleys no nothing just exhaust and intake
