I had a blast! I'll be back in the spring, after finals. Hopefully with more grip...

I didn't notice a lot of body roll in your video. I'm assuming your 940 isn't stock. A bit more negative camber and a set of sticky tires goes a long way towards much quicker times. It sounds like you have rock hard street tires on your car. Greg Ervin and I used to run his 740 Turbo in Autocross. It started out as a stock 740 T when he bought it and ended up a stripped out streetable race car. He still isn't done modifying it. Maybe, he'll be back racing it by next season. He came out for our clubs last event this year with his 242 GT.

It is bone stock, on Kumho all-seasons and 15s. M90 swap means I have to run with the big boys but don't let that fool you. I don't think I'll go that far but certainly there's some margin of error between "couch" and "race car"



In hindsight, maybe asking the people that walked up to me if it looked like I was pushing was a little silly...

[2manyturbos]

Lol. That did not show up in your video. I have pics of my 780 Autocrossing that look like the rocker panel is touching the ground. I thought I heard a manual trans take off when you left the line. I could hear your rear tires squealing.

[redblockpowered]

Going back for revenge on Sunday. Only upgrades have been to the driver, unfortunately the IPD bars I bought won't be here in time. The body roll only bothered the instructors anyway.

[2manyturbos]

Cool. Work on trail braking late into the turns to get that front suspension loaded ahead of time. It will get your 940 to rotate much better. If you can, try left foot braking. I haven't driven a manual trans 7 series in so long I don't remember how the pedal layout works out for left foot braking. If you can do it successfully, it will completely change the way that 940 works on the course. I finally ran on a course big enough and unobstructed course last event to work on left foot braking in my Mustang. It took me about 7 runs to get it right. The difference was significant. I have one more event myself this Sunday. This will be it for all Autocross in the NW until Feb/March. Post up your results. Good luck out there.

[redblockpowered]

I had a blast. Car was effectively the same as last time, setup wise so I just focused on improving my driving. I had a lot of success cornering at part throttle to keep from overloading the front suspension, in addition to trying to make smoother inputs. I don't have pictures or video from this time but the course was a lot more open (same venue) which suits the car a lot more. Finished 111th of 125 in raw time which I'm happy with considering what I'm working with (stock 940T except for M90 and boost controller) and the level of experience I have.

Cool. Keep at it. I'm surprised to see 3 Volvos listed in the results. That's practically a Volvo convention considering the venue. How many runs did you get?

[redblockpowered]

They were planning on six but due to the excess of cars we only got five. I was pretty surprised to see other Volvos kicking around too.

A ride along from inside the car on my last session.

ORP is pretty hard on tires in general, and the RE71Rs are also some of the fastest wearing Extreme Performance tires that have the 180TW+ rating that allows us to use them in endurance racing. The RS4s have a much longer lifespan and don't mind the constant abuse nearly as much, but they are typically a little slower.

I need to check out the videos still...

w00! I assume you don't have any more events this year? Good job getting out there and learning. Do you feel you went faster this more recent time than the first time in the video? I get to practice trail braking a lot on the street when I'm hustling my wife's old Elantra around at speeds it shouldn't be going to prevent ripping the front tires off the wheels, haha. It definitely helps to ease into corners when there's so much body movement to get the front planted first!

GREG! I haven't seen him in years. I'm glad to hear he still has the car and I wish he would trailer it up to go drag racing again for fun. He was one of the fast cars years ago even with a basically stock car.

Kyle,

For a heavy car like my Mustang, what are a couple different makes of tires you see working for a combination track tire, possible Autocross tire? I'm planning on running more track days and will likely buy another set of wheels so I can have something that will hold up. I will still have a set of RE71Rs for Autocross. They work incredibly well in that application. I'm not out to set top lap times on the tracks. Something that will last so I can do track days without spending a fortune on tires.

[klr142]

Hankook RS4s are your best bet, for certain. They're not going to be like the RE71Rs if going for fastest at the AutoX, but they're very good for a long long wearing tire that holds up to the track. I don't know what they have for tire sizes that are near your factory setup, but something close should suffice, I assume!

[2manyturbos]

Thanks. I’ll look into what sizes are available and go from there. I don’t have to comply with any sort of rules for what I’m doing as far as track days. I’ll just find something that is appropriately sized for the car.

Best bang for the buck in my opinion is getting take offs from an SCCA world challenge team or some other similar series. Make friends with well a sponsored team and you will generally have no problem getting them for a reasonable price. I was paying on average $400 a set for practice take offs which were guaranteed 1-2 heat cycles with 75% depth or better. I ran dozens of track days and autocrosses this way over the past decade. One set would last a full auto x season and 1-2 track days. I was running 17's though as they were the most common size at the time. The spec Miata's were still running 15's then.

[2manyturbos]

Good idea. It may be hard to find take offs in 19”. The brakes on the GT are so big it requires at least a 19” wheel to clear them.

[R32RennSport]

You might have a tough time there, the biggest that I normally see are 18's but a lot of modern stuff runs bigger sizes, might want to check the 911 cup cars and such.

I understand, it's just that they are relatively cheap and last longer than most all of their competitors by a sizeable margin. Teams sometimes get more than 24-36hrs out of a set where the RE71Rs won't last 12.

Testing image hosting that obviously didn’t work. Lol

[2manyturbos]

I got in one event before the shutdown. I had to run in the morning group which was on cold, wet pavement that was akin to driving on ice. Smooth inputs were key to getting any kind of run at all. Very few cars in the morning group ran sub 60 second runs. I made 6 clean runs, the best of which was a 58.3XX run. By the 2nd run group the pavement was drying out and their times dropped 5-6 seconds over the duration of their session. It was that slick. Usually, the rain only accounts for a 2-3 second drop in times. The 3rd run group had almost completely dry pavement to run on and their times weren't much better than the 2nd group. After all three sessions were over there was enough time for fun runs and that's when the GT came into its own. My best run was a 53.032. That was running on Michelin Sport 4S street tires. My first time driving on these. It was too cold when I left at 6 AM to head to this event 2 hours away at PIR to run on my RE71s. It was 29 degrees out when I left. It took 10 minutes of running my car to get the 1/8" of ice to melt off of the glass. Since this event, everything has been canceled or postponed. Our next tentative event is May 16/17 at Dallesport Airport. I'm keeping my fingers crossed this one will actually happen. It's so bad professional auto racing has resorted to virtual racing. I'm not kidding. Here is my version of virtual racing for you guys.

Morning run on the wet, ice cold pavement. 58.3XX seconds.



Afternoon fun run. 53.261 seconds.

Lucky! Nice work.

Thanks. Have you guys gotten in any racing this season? I know there was at least 1-2 Lucky Dog races before the shutdown.

[klr142]

Nope. The first race in the Pacific Northwest was the end of this month. And it was canceled along with another race in California. Maybe at the end of May at Pacific, if we’re lucky! And hopefully we get the car done! LOL

[2manyturbos]

As of last week racing has resumed in the northwest. This weekend I had my choice of 3 different events within reasonable driving distance. Two were in Washington, the one I picked to run at was at Hoodoo Ski Bowl near Sisters, OR. The setting there is awesome. It was a bit weird with the social distancing requirements, face masks, hand cleaner, 25 person cap on the event etc. All that said, it was nice to get back behind the wheel. Clubs are scrambling to get back on the track now that WA and OR are allowing events to proceed. Two of the clubs I belong to are having a combined event at Oregon Raceway Park on the 20th of June. It was originally scheduled for a month ago, however, the lock down required postponing it until June in hopes the restrictions would be lifted by then. Here is video of my best run yesterday. It's new front tire time. They don't stick anything like the used to. They were pretty much done at the end of last season after having the equivalent of ~ 150 Autocross runs on them.

Hackster is up in Washington running at Sanderson Field this weekend. I was registered for that event and then switched to the Hoodoo event when we got the go ahead to hold it.

Cool. Is that a 1963 Galaxie you’re driving? You have to post a picture of it in this thread.
