You guys are in VA, but for anyone in SoCal following this thread: I will be out at Streets of Willow on February 11th, unless the weather gets ugly.

I'm going to get a LeMons team together in the NorthBay area pretty soon. Will be looking for a junker NewBeetle to set up for hopefully Dec Sonoma and maybe Sept Buttonwillow races.

I'm curious about the exhaust tank too. I hope it's not a keg warmer

I took the Jetta to Streets of Willow again with Extreme Speed Track Event, running clockwise. I was running a (not so much) blistering 1:37 lap time. It was an absolute blast! I had a few students with me, so I am blaming the slow lap times on the extra ballast .
I had a couple of people comment that they had never seen a TDI there before!

Unfortunately I took apart my Countour Camera to install a microphone cable and I left my Nikon at home... so no pictures from that event.

Hello The Lemon races ask for a theme so we where the Boston Smoker.
We cooked our lunch in it we had ribs and and brisket in it my brother Rick prepared.
It was a big oven ran 275F most of the day.

Drove the old 99.5 last weekend. Not that fast but fun. The tall, all-season tires made it a little bit more drifty, lol. anyway. have to run what you brung.

Looking to take our 2011 TDI wagon out to AutoX in a couple of weeks, any guidance on what kinds of tire pressures to start with? I'm running 235-45/17s (Pilot AS3+). I've only done a couple of days so far with our Miata, but the wife is going to take the novice school so I'm going to bring our wagon along to play with while she has the Miata.

Thanks, John

Sofar Ive found that "it depends". With the Michelin super sports last year, I slowly kept bumping up the pressure as I got more aggressive to keep the sidewalls from rolling over. Adding the rear sway bar made me change the pressures as well (a bit less overall). I need to check my notes but I believe I was at ~42psi in front by the end of the season. This year I have a set of Bridgestone RE-71R which have significantly stronger sidewalls (and very sticky). I had started out with the same pressures and found the center was getting hot and not the outer edges and so I bumped down to 40psi front, 42PSI rear. Over this last weekend at a very cold/wet HSAX drivers school I was running 38PSI front, 42PSI rear which felt good but I didnt take any temperature readings. Ill try that as my starting point in my next event.

If you take a silver sharpie and make a mark from the tread onto the sidewalls, you will get a good indication of how much your sidewall is rolling. If its too much, increase pressure.

The general recommendation Ive heard is start at +3PSI over recommended and adjust from there. If/when you want to do something about the understeer problem, raise the pressure in the rear until it can start rotating and/or add a rear swaybar.

Thanks - mostly I was looking for a starting point so I'll pump them up to 42 psi when I get there and work down from there. I've got a box of chalk to mark the sidewalls so I'll check and adjust after each run (I'm a complete novice and this will be the first runs in this car, all the other runs have been in our Miata, so I'm a little nervous about actually getting my act together to get the adjustments done in between runs). I do have a rear bar (GTI bar from the scrap yard) and it made a huge difference in getting the car to rotate in the winter school I took last year.

Just to confirm - your pressures are hot, right?

I run track days with NASA. I also do an occasional autox with different groups if the venue is interesting (did the night one at Xenia speedway last fall for ex.).
Brunhilda is pretty stock. Diesel Power fuel box, GTI rear bar, repurposed Merc wheels ( 1/2 in wider and about 15 mm more offset) wearing Falken Azenis RT625K's and Hawk HP+ pads on the front.
Not the fastest girl at the dance but I have aggravated the dickens out of more than a few "faster" cars at Mid-Ohio. I've also snagged a few trophies at the autox meets as well.


Evidently I haven't posted enough to be able to post pictures. I did put a couple in the Jetta folder to grab later.

More or less. It kinda depended on if it was during a set of runs or if it was after a long break. This year I now have a pyrometer and I'm going to try adjusting pressure based on that feedback.
