Amazing! I have the exact same car as you (2017 Jaguar F-Type manual), and have used it extensively on track. However, I installed the LSD from the V6 S 3 years ago since this option wasn't there. I'll probably run with that differential until it's worn out, but then I'll for sure be interested in one of these! Also on my wish list are solid/ aluminium transmission mounts as I find the gear shifting to feel "mushy" with especially 2nd gear giving me issues when everything is warm after a couple of laps. Anyway, really happy I found the channel and will follow everything you do closely! :)
Jon. Great to hear. Check out the videos on the LSD tear down.. and i will also post a new video on LSD rebuild. Sorry to hear that your car’s shifter feels mushy. The rear tranny mount isn’t the stiffest, so could use an inspection. Or do you see any engine tilt under torque?
@@OncaEngineering Not sure about the engine tilt, I'll investigate as soon as the car is out of winter hibernation. I'll get back to you in a month or so. :)
@@jonaslundin5508 I am thinking about your shifter. The lower portion of the shifter does have a plastic ring which locates the shift stick ball into the nylon cup. If this plastic ring is loose, then the bottom of the shifter may pop out and feel very sloppy. Can you lift up on you shifter and does it pop free from the ball-joint cup? or is it captive?
@@OncaEngineering It doesn't pop free, but I also only get the problems after a couple of laps when the car is hot. When the car is cool the gear shifting feels notchy and precise. After a couple of laps on attack, it feels like it is difficult to go from 2nd to 3rd gear or vice versa, especially if I'm driving through a corner. I was therefore speculating that it might be due to the transmission mounts (which would explain the problem while cornering) but I struggle then to explain the heat issue. Unless the existing mounts get softer when hot?
I should add that I'm competing in Time Attack and pushing the car (and myself) to the limit. So I can imagine this could be an issue rarely encountered by other drivers. :)
My pleasure. And you will soon have a new diff for your F-Type. I will be building units after testing the first one. But first i have to get my back in order after torquing it making this video!
Yeah, I was motivated to develop this solution which is lower maintenance than the S-model LSD, and applicable to more than just one gear ratio (3.31:1) and I really want better cold/rainy day grip, as well as better corner exit grip. I think an upgrade kit for the rear differential is within many home mechanics capability, let me develop the tool list and publish the instruction set to gauge interest.
Howard, this ATB should work with most Jaguars equipped with the Dana 44 AdvanTEK rear differentials. This covers most 4 and 6 cylinder gas powered Jags from 2014 to 2024 (F-Pace, F-Type, XE, XF) take a picture of your rear differential and i’ll get back to you. OncaEngineering at Gmail dot com
Good question. This video was about the F-Type V6 models which do not feature an electronically controlled rear differential like the V8 models. Rather the V6 cars have two options, and now a third (base model = open diff, S model = Friction based LSD, and now Quaife ATB). The Dynamic Stability Control (DSC) works well with these three options, but realize that the base model's open diff provides the least rear axle traction in slippery conditions, while I find the LSD and Quiaife ATB provide a good level of grip before DSC kicks in to assist. Look for my V8 eDiff videos for more info on that application.
James, I specified the Quaife ATB for the rear differential on modern Jaguar V6 and I4 engined cars. Note the V8 F-Types usually feature an electronically controlled rear differential which is a bit more complicated. The front differential is smaller than the rear differential. AWD V6 cars can still benefit from a Quaife equipped rear differential. It just has to maintain the same gear ratio to match the front differential ratio. Do you think there will be good value in upgrading the front differential to a helical ATB?
I wonder what the front differential looks like on the AWD Jags… they could be based upon a Ford unit, or perhaps an other application that may offer an LSD upgrade. It just takes a motivated individual to purchase a unit from a junk yard and attack it with some calipers to get the ball rolling.
@@OncaEngineering I appreciate the reply, I'm seriously considering building an ultra high horsepower all-wheel-drive F-Type to compete against some of these F150s that are running the streets. Diff strength is very important. Your Quaife upgrade gave me hope.

Thanks for sharing your progress Herman!

Definitely interested in a kit! I also have a 207 F-Type V6 Manual (non-S, so open diff). Looking forward to future updates!!!

Excellent stuff!
Audio has some fuzziness and static at the beginning. Might've been peaking or something.
Thanks for your complement.
Sorry about the mic issues. Still learning my equipment.
Question would this work for the Jaguar xe 35t r-sport rwd with the open diff?

How does this LSD effect winter driving traction control? Yes for the V8 SC e diffs!

Is the front diff on an AWD F-Type the same as the rear? If not, does Quaife offer a specific one for the front of a 2017 F-Type R?
