Would love to see where you mounted the Volvo EPS setup. Just pulled one from a 05 S40 for my 00 RS track car build.

I'm not sure where his is mounted but I removed the factory battery tray, drilled a giant hole to recess the pump motor down into the fenderwell and bolted it up there.

I'm using the model with the integrated reservoir.

I don't think the pump was having an issue after changing some other components around but I also added a little cooler in the return line.

My hoses are rather short this way as everything stays on the drivers side of the car. I use an AN adapter on the pressure feed with a hydraulic face seal type o-ring (the factory fitting is some oddball metric tube nut that I couldn't find anywhere).
The return, after having fitment issues with an AN adapter I ended up cutting off the stock return pipe and double crimping on some Parker 801 hydraulic hose for a return.

Aczwild and Barge: My installation is not something you would do in a street car. Because it's a full on race car with no passenger seat too, we mounted the pump to the passenger side floorboard, close to the oem ecu. We drilled holes thru the floorboard to the Mooresport rack, which makes for very short lines. We remote mounted the reservoir up on the dash bar where it's easy to see the level and add fluid. Sorry no pics, I'll post a couple later.

On the rack we used the Mooresport AN adapter:


We have an issue with the Mooresport subframe fitment, it rubs on the steering rack rubber bellows and during the course of the race we wore a tear in it. We noticed this when we first setup the rack in the subframe and hoped it would take a lot longer to cause a problem, but no. We are hoping to find a smaller rubber bellows that will fit and not rub.

Lots more upgrades happening over the winter. To start with we are probably going to entirely redo the wiring and gauges with the new AIM PDM + Display + Logger. Most of the aftermarket gauges will be replaced with AIM sensors and the display. Also a mount for the new Garmin Catalyst. We doing CAD (Cardboard Aided Design) now to see how they will all fit.
AIM PDM/Logger
https://www.aim-sportline.com/en/pro...dm08/index.htm
and
Garmin Catalyst
https://buy.garmin.com/en-US/US/p/690726

In the spring I'll be giving y'all a review on both products.

We are also having an issue with boost creep. It doesn't show on the dyno but it does on the track. It may be related to the dyno being at 4,000' and racing at sea level. We have talked with ATP and have some options on how to fix that issue.

Other mods: We are replacing the -AN line from the DS tank in the trunk back to the oem oil pump intake with solid tubing most of the way. More flow, less restriction, less weight.

Rear Diff Pump & Cooler and sensor to the AIM logger.

The windshield has taken a beating over the years and has a couple of cracks. We are debating replacing with a polycarbonate windshield from racingshields.com. We made our own rear poly windshield so we may make our own front one too. The issue is scratch resistance in a car that could go several hours racing in the rain with the wipers on. Racingshields makes strong claims about their scratch resistant coating.

The flat bottom has some off track disturbances to it that need to be fixed.

Thanks for the insight! This will be going into my '00 RS that is full racecar and I pulled the Volvo EPS with the remote reservoir as well as I was thinking of mounting it in the passenger side footwell too with the reservoir mounted to the dash beam or door bars. I like your idea and would love to see how you routed the lines to avoid the exhaust system.

Default Track Days Update

Saturday at ORP was a downer. The STI was running lean and still has boost control issues despite installing a new downpipe and re-plumbed the Tial EWG. A compression test showed fine, but the leakdown test showed a leak in an intake valve. I have a spare engine ready to swap in, so we called it a day and took it to the shop to start the swap.

We spent Easter Sunday at Oregon Raceway Park running the 818R. It ran great other than a minor gas leak around the fuel sending unit when the tank is overfilled.
5 sessions. The first was with no wings, no engine covers, just to see if anything had sprung a leak or come loose over the winter. Then I did 4 more sessions testing wing configurations.
It was a cool day, in the 50s and 60s, and very windy in the afternoon which made the aero testing not very valid. But I was sure pleased with the engine/tranny data:

Coolant Temps under 190 all day, mostly in the 170-180 range.
Oil temps 190 to 196
Oil Pressures rock solid thru all the high G turns tracking with RPMs, from 55 psi to 65 psi.
Trans temps averaged 145. Never went over 155.
Crankcase Vacuum was excellent, its stayed in the -8psi to -3.5 psi the whole time. It never went positive.

It's so nice to track all day with solid temps and pressures!

I hooked up my new Garmin Catalyst, along with my AIM data and Racelogic Video HD2 Vbox. Up until now I've considered the Video Vbox to be the best driver improvement tool but I think the Garmin has changed my mind. There's nothing quite like having the little Garmin lady's voice in you ear, "At next right turn brake later"; "At next left turn apex earlier"; "At next right turn brake softer".....and so forth. She seems to speak to you on no more than three places on the track on any one lap so she's not overloading you on instructions. And she even gives compliments when you follow her instructions!
And the post session review process is so much less complicated than AIM and Vbox.
It's miles better than an AIM Solo. It doesn't have al the capabilities of the Vbox, but the Vbox doesn't talk to you while your cooking around the track either. The Vbox has a predictive lap timer, and so does the Catalyst, but having the voice is incredible.

It has an internal speaker and hooks up to Bluetooth thru your car's speaker system too, but in a race car there's no way to hear the internal speaker. So I bought a set of Bluetooth earbuds. They are uncomfortable under the helmet at first until the helmet liner compresses around them. but then the first time she says "Carry more speed thru the corner" she has you hooked.

I haven't figured out how to download the data or save the video. Still working on that. Garmin wants you to save it in the their cloud account.....

Next up is Test & Tune on Friday April 30 at Portland International, then racing on Saturday and possibly Sunday too in the 818R.

Curious to see/hear the Garmin video overlay experience if and when you get around to it.

I've been looking for a more seamless video/data overlay than my iPhone/Harry's Laptimer/GoPro. It worked awesome for a few seasons, but now I'm getting all kinds of frustrating connection and data overlay issues.

Good luck on sorting the car issues out soon!

Great info. I have my Aim EVO4S and GoPro but that's it. What you have sounds interesting. What G's do you sustain? I don't like my data going to a cloud that I have to pay additional for.
Thanks and keep up the info and feedback!

The Video/Data integration is outstanding if you are using the Review function on the Garmin device. The AI software shows you specific places on the track where it suggests you can improve. Awesome!

I looked further into downloading the video and data to post on YouTube and have on my laptop at the track and desktop at home. It's Awful! There is no explanation in the Owners Manual on how to do it, but I eventually found one on the Support website under the FAQs. It's possible to download the video at MPEG 4 files, but the data doesn't come with it. It's just raw track video with no data overlay. And the process is very buggy, it failed several times.

There is a second micro SD card slot onthe side of the Garmin where if you put in a card it will hold the video (they say). That would make it a lot easier to load the files in a PC/Laptop. I've loaded a card but not tested it. But it still won't have the data.
Garmin spent all their engineering resources on the AI in this device for this first version. I expect updated software will make the video/data export a lot better eventually.

The Garmin cloud account is not for video/data. It's a BS sharing web platform.

Scargo, the 818R on 200 treadwear street Toyo Proxes R1R tires was consistently generating 1.4 to 1.6 Gs lateral and 1.15 to 1.17 braking. I'm sure I can do little better on the late braking Gs, I have yet to lock them up front or rear. I'm pretty happy with the lateral Gs on the 200 TW tires.

Hey Gator

I just re read your post about the windshield and was watching IMSA a few weeks ago

Perhaps a solution like what the Endurance teams do with a removable film for protection ?

I'm going to have to go back and do a refresher on your 818R powertrain.

As for the Garmin, it sounds interesting. I'd be curious to see if the SD card fixes the headache, but I would be pissed about not being able to pull my own data or have an overlay on the video....which you would think it should do.

That is an option for sure. I use tear offs on my helmet visor when driving open cockpit/no windshield cars like the 818R. For helmets tear offs are cheap, but for windshields they are spendy for a consumable. Not to IMSA and NASCAR budgets, but to racers like me. Especially since they don't make them pre-cut for Subarus. However I will consider it. Thanks.

The 818R currently has a stock 2015 STI 2.5L block. FMIC with a mile of IC piping that you would think would have a ton of lag but I have no problem with it. 5 speed with LGT gearing and 4.11 final. Dyno at 226 RWHP.

The Garmin Artificial Intelligence is built-in to the unit and likely will be a long while before it could be used outside of it, if ever. For the intended purpose it's a great value. If you need great video with data integration the Video Vbox HD2 is my first choice for driver improvement, the AIM system with their Smarty Cam would be #2. The AIM is better for logging sensors on the car, the Vbox better for comparing different drivers. But both are more expensive than the Garmin and in most ways aren't as good for the amateur driver.

Yeah I figured it would be expensive unfortunately

Perhaps a ceramic coating or something of that nature might help
