Tip from over here in the Uk, get the steering wheel straight. It gives you consistent references from the seat, it's also why you are shuffling your hands round the wheel. Look at pro drivers, the hands don't move much at all (around the wheel). Great job with the car. All the best for the next event.
“Andy and Aaron, your job today is drive the FTreeKitty to the US and bring back parts from an awesome salvage yard”. You lucky bastards. I’m only here for the music.
I really enjoyed this episode Rich all your work is finally paying off, can't wait to see you do another segment with your instructor when the weather is more in your favor.
Ford 8.8 from an expedition can be adapted fairly easy. It has a front mounting point and you can make a mounting bracket to bolt to the rear cover bolts. Digferent Gear raios and posi ar readily available (and pretty cheap). Maybe an option??
If you incorporate load cells into the wing you could record the amount of downforce and in conjunction with some wind tunnel data and data analysis dial in just the right amount of downforce for the track and conditions. You could even put the data into your simulator.
I've been watching your videos for a while bro. And i must say you do build some cool shit!!! Between you and Derek from vice grip your content is PRICELESS. You guys always put out a video that's full of knowledge and humor😂 keep up the good work! MUCH RESPECT HERE! SINCERELY, JAMO
That track prep is hard on the equipment, but is dose give low ET’s. I personally feel the prep is not a good deal. I am surprised that you are using a stock rear differential! The car looks to be difficult to work on and overly complicated. The car does produce interesting content, and I can see the amount of work that you’ve put into it. Best of luck with your Audi.
The air is often cooler (in tunnels and snow sheds as SP found out) but being closer to the track it is dustier. The dust gets blown through the radiators causing erosion of the cores. Out in the desert, the air might be cooler higher above ground in summer. GE have little choice since the radiator fans have to be below the radiators but above the intake grilles, so they are more or less at frame level. By placing the fans above the radiators and by moving the air intakes upward, less road dust is sucked through the radiators and the speed of the dust is less since the fans are further away sucking instead of just beneath blowing. So EMD radiators should last longer. But the slower flowing air means that more or bigger fans are needed. An SD40T-2 had two 48" fans blowing while and SD40-2 had three 48" fans sucking. At full power, the SD40-2 had one fan's worth less power to the traction motors. I think the SD70 ACe has two 52.5" fans and the SD70 ACe-T4 has three 52.5" fans. Equally, the ES44AC had a single big fan (sorry, I don't know the size) and two smaller fans cooling the inlet air in the intercooler. In the ET44AC, there are two big fans and the inlet air is cooled by water that goes through the front radiator elements. I suspect that more power is used cooling the ET44.
When I first clicked on watching this video I said to myself he's an all-wheel drive on a slick sticky quarter-mile track he's going to break something right away!! And sure enough he did! There's soooo much traction on regular tires you've got to ease it at the line!!
Mosport is my fave track. Raced back in the 80's-90's there it's like a roller coaster ride. Laguna Seca is 2nd but it's 40 hrs away unless you have a Neil Smith co driving 38.5 hr best time ever from London Ont to the track. Up hill breaking into a blind corrner is a blast. Car is coming along nice considering from what you built it with
I love the sound from the Audi, cant wait to hear the real motor when its ready to boogie... **Suggestion** To set the rear wing, why not put it behind a running propeller plane(tethered of course) & light up a smoke flare to see how the air flows over the roof to the wing, that might help with downforce.
There's the saying "tires are cheap clutches" - and too much grip is a thing. Axles, driveshafts, differentials, gears, housings - all can go boom when the tires are literally glued to the ground (drag strip). Especially in cars with a manual transmission (except with slipper clutches). This is the reason why drag racing cars have a) often a converter and b) a VERY beef driveline. ✌️
Right as you mentioned Cleet and lz I was thinking of how many times I’ve seen those guys run track/drift cars at the strip and break axles and diffs lol. Always worth a shot though
next time you go out you should put a few dozen strings on the back to see what the air is doing. You already have the cameras. Glad you finally got some laps in.
6:27 that'll buff right out. Lololol this happened to me with the front differential on my Nissan Titan. The pinion walked away from the ring gear and took the aluminum case with it. Haha
The rear-end issue could be fixed with 8.8 independent from mustang, the cooling problem have you ever thought of the air is not moving out the back cause of the air flow over the car....
I would put some long travel shocks on the Audi so that it doesn't lose traction. We're also handle well on the road course have you ever seen a prerunner race a road track.
A good diff to look into comes from a cadillac. The video I seen it in the fella said it was rated to take 900+ horse power but idk if it would be the right gearing however I'm sure you could change stuff up inside it but atleast the case would be strong enough for your needs. If you want to see the video or for me to get info let me know and I'll get what I can to help. Love the videos man thanks.
The Ford 8.8 is another good choice. It has lots of aftermarket. And if you wanna get fancy, you can get a Super 8.8 from a Mustang. Not sure how you'd integrate that into the Audi AWD system though.
I'm only at the 10min mark, but i think You guys should really look into a ford 8.8 retrofit for the back of this thing, Weld up a subframe and spin up some flange adapters. Theres so many 8.8s with limited slips, and theyre beefy, im sure you can find one with the correct drive ratio on it. Never have to worry about that again.
I’m 6’3” and I’ve got a little Asian buddy that can’t drive any of my stuff either 🤣 I took his Ducati F4 Superlegarra for a ride and I’m sure I looked like a Mario kart character on that thing!
Have you considered moving to something like one of the newer IRS rears out of a Mustang? The "super" 8.8 is EASY to find, cheap, and WAY stronger than the Audi diff I'd bet.
Just another Ford 8.8 suggestion. The Audi diff is a nice torsen unit, the 8.8 should have some good LSD options in either clutch type or torsen. Getting matching gear ratios could be interesting, not sure what Audi was using.
It's like people who really appreciate the sound and feel of a steam engine. Technology changes. One day, there'll people complaining about those new silent drives and wanting the whine of an electric motor.
It maybe worth spending the time stripping that broken diff and blasting it followed by a session with vince. After that build a steel brace like they do for rear axles on 4x4 rock crawlers. As you say their rare and those diffs arent being built anymore . .
on my to do list... making rod bearings out of some 58'000psi tensile 11 gauge sheet metal, because the aluminum ones are weak 15'000psi tensile and over priced with 500psi tensile lead/tin in them.
If the tensile strengh of the rod bearings matters something has gone very very wrong. Firstly they are ony stressed in compression, secondly during operation the bearings and the crank are seperated by an oil film.
🤔 well that's racing.... if you smoke another diff you should have a look at a winters quick change diff especially with the new motor and built gearbox... you will get that elusive quarter mile time👍

I love how each of your projects has its own intro. That's a nice touch.
I like the Skid Factor shirt.
I think, of all your projects that I have followed, this one is my favorite.

Those laps looked like so much fun!
I'm a simple man. I see a Skid Factory t-shirt, I thumbs up
You and me both, bud

Some good instruction going on there. Nothing better than a wet track day.

I know its a long way from home but it would be super cool to see this thing take on Gimli Motorsports Park at an Open Lapping Day!

Damn that sounds good. That was a super fun episode.
That car is so overcomplicated! I love it.
next time you go out you should put a few dozen strings on the back to see what the air is doing. You already have the cameras. Glad you finally got some laps in.
Look up Daniel Bois, he coaches and has thousands of laps around Mosport. He races in the NASCAR Canada Series as well.
Hey Love the car!! And thanks for reading my time ticket at TMP!!

@DEBOSSGARAGE try a Ve Ss commodore diff trust me I'm Australian they can take the power 😉
Would have to put it upside down as the audi diff rotates the other way

Theres so many 8.8s with limited slips, and theyre beefy, im sure you can find one with the correct drive ratio on it. Never have to worry about that again.
Just posted that myself, the super 8.8 from the late model cars are IRS and would be perfect. Easy to get, cheap, and wide range of ratios out there!
I’m 6’3” and I’ve got a little Asian buddy that can’t drive any of my stuff either 🤣 I took his Ducati F4 Superlegarra for a ride and I’m sure I looked like a Mario kart character on that thing!
It might be a good idea to source a Ford 8.8 center section from a modern Mustang IRS setup. Hopefully you could find the same ratio you need.
I never knew a place like Vinces existed only a couple towns over from me! I gotta start going there
that engine sounds amazing..
Would really like to see this run at Knox Mountain hill climb in Kelowna in May.

Gripper Differential is what you need. Uk company check them out for front and rear differential. I have one in my urs4
Hahaha I have the same fast wheels on my 00 Buick century but in gold. SICK DB! They're pretty nice rims! 😁
If you want to figure out the aero, you just need to buy wool and tape! 👍
AWD on a prepped surface and a hard launch, whar did you think would happen?
I don’t care what anyone says the whine of an electric motor will never replace the raw sound and feeling of power from a V8.
Disagree
@@ΘάνατοςΧορτοφάγος that’s ok. Have a great day.
It's like people who really appreciate the sound and feel of a steam engine. Technology changes. One day, there'll people complaining about those new silent drives and wanting the whine of an electric motor.
Sound no, feeling of power yes.
Put an audi rs2 diff in it, that one is stronger 💪🏻
put small radiators behind the front bumper like a porshe.
Would be awesome to get an invitation to Pikes Peak race.
When are we gonna get a Review on the Ram Eco Diesel?
Wow!
The back gounrd music could be a little quieter
whats the ring gear in it? 4.10 or? if so just get a ford 8.8.
Im surprised they let you race without a firesuit.
Looks like a porsche 993 or 996 front diff c4s ?
It wouldn't be that hard to fab up a dana 70 into that little thing, with a custom housing. :) .. You know a welder.
You can never have too many access holes.
time for a super 8.8
It maybe worth spending the time stripping that broken diff and blasting it followed by a session with vince. After that build a steel brace like they do for rear axles on 4x4 rock crawlers. As you say their rare and those diffs arent being built anymore . .
I feel like I took this car out for a test drive 10 years ago, might be a different one tho.
Youll have to stick to rolling start drags from now on
Thing is mean. Just keep on givin er

Need to run time attack
time for some Ford parts. a built 9 inch is near indestructible.

on my to do list... making rod bearings out of some 58'000psi tensile 11 gauge sheet metal, because the aluminum ones are weak 15'000psi tensile and over priced with 500psi tensile lead/tin in them.
If the tensile strengh of the rod bearings matters something has gone very very wrong. Firstly they are ony stressed in compression, secondly during operation the bearings and the crank are seperated by an oil film.
Excursion diff.
Fans work much better as pullers on a radiator. It will make much more even flow across the core.
Can you stuff a older corvette rear into it? Its got IRS
🤔 well that's racing.... if you smoke another diff you should have a look at a winters quick change diff especially with the new motor and built gearbox... you will get that elusive quarter mile time👍
Bots are here early!
You guys broke a rear Torsen diff? And stole another one from the US? Sad face. 😁
