Looks like im going back to Laguna Seca on Sept 3rd for another track day. I know my car will overheat and I will be logging the data this time with my laptop in the front seat. I had Weistech get me another ECU load that I can implement once the car overheats so I can continue to drive in another session. Does anyone know if adding an extra quart of Mobile one while racing will help? I know from my aviation experience oil is a major cooling factor, but those engines are air-cooled.

Too much oil in an automotive engine is worse than too little oil, has always been my leaning, although I try to keep it just right.

"When too much oil is added, the level in the oil pan becomes too high. That allows the crankshaft to come into contact with the oil and essentially aerate it. The result is a foamy, frothy substance that cannot properly lubricate the engine" - J.D. Power

I went back again, got a 1:49 with a theoretical 1:46. Still lots of room left. It went into limp mode differently this time at about 9:33. I think it was getting too hot (oil got to 230f), but I didn't pull the DTC before I reflashed the ECU between races. DTC's were clear and did not resurface when I left the track. Before anyone bashes me for losing to a GTI should know it was heavily modified on race tires.

Is your gear reading right? Your car does 50 MPH in first gear? 25 mph at 3k RPM in first? 50 MPH at 4k RPM in 2nd?

Don't trust the OBD readings, I noticed that too trying to see both my shift points and speeds, the Bluetooth connection is VERY laggy and inconsistent. I may opt for a USB wire next time, but don't like the wires. Looks like I'm going back on Sept 3rd, a Friday to Laguna Seca.

Not with speedSF you arent, found another org to ride with? Motorsportreg doesn't have anything on the calendar :)

10-4 on OBD, I noticed the same on my footage. So I guess I'll ask directly, do you get throttle lag coming out of turn 11? It’s literally the only thing that bugs me about driving on the track (besides personal skill development)

Hooked on Driving suggests running your oil on the low side on the track. Frothing is a problem. Not only for lubrication but this can also kill your AOS.

I always run my 997 at the lower level. But the cooling does come into play. My oil runs 25F hotter than friends who run full. And with that heat comes expansion. More than you might think. My low level becomes an almost full level by the time the temperature reaches 275.

So more oil to limit temperature and reduce expansion, or less oil to allow expansion when the temperature soars? With over 140K miles I remain in the less oil camp.

Not too much of a lag, I'm running high RPM in 2nd. watch at 2:02 on the video post #35. As I come up to the turn, I downshift from 4-3 then right before the turn I go to 2nd. When I hit the turn im between 4-5k RPM with plenty of power at the wheels. I could make the wheels spin all the way through the turn and into the straight, but I'm trying to keep them planted. Another reason I am getting an R compound tire.

Here is the calendar for NCRC.

NCRC 2021 Event Calendar – NCRC

Would love to see any of my GLA friends out there too!

I had the Weistec Turbo upgrade, ECU and DP. I was having problems with the ECU limiting power and had to quit this race and was too nervous about the next races so I quit for the day. My best time with traffic was a 1:53
Looked like a great time despite some interesting driving by a few guys in front of you 😬 The GLA definitely seemed like it loved that track!

I got it under 1:46 with a 1:43 theoretical. Tough to do with traffic. I'm sure I could pull sub 1:43 pretty easily under the right conditions and with no traffic.

I just blew all my next-track-day money (was gonna be Laguna) on some backpacking gear (Emigrant Forest this year!) So we'll see if I do Laguna this year, as I'm absolutely driving Buttonwillow in late summer. But for sure I'll send you a note if I find the spare resources to do a Laguna day. You want me to let you know when I register for Buttonwillow? My wife has a friend in Bakersfield, we'll probably stay there and I'll do the drive out and back on track day. Should be half the driving of staying 2+ hours away in San Luis Obispo, even if it's hotter and less scenic! Always a good time to represent the GLA together in the paddock.

It's a really cool track with some cool features like esses, a long sweeper, and some hyper-fast turns on a track with zero walls besides Honda wall at the start/finish.

Yea, I was thinking about Sonoma or Thunderhill. The heat of the Bakersfield area is brutal, and you know what heat does to these cars. Laguna is always relatively cold and that 40-degree difference adds up!

welllllllllllllll............

I have Weistec stage 2 and piggyback before then, so overheating really hasn't been my problem like you :) I dunno if your downpipe is insulated or not, but I'm taking your experience as a cautionary tale, I selected my downpipe based on the model that integrated the best insulation possible. It was not cheap, but heat was NO issue at Sonoma last month.

I've been talking to Weistec, have you considered water meth? That is my plan, as I don't plan on upgrading my heat exchangers like you. They mentioned that for people like me, the primary benefit is enhanced cooling. For stage 2 and lower there is no tuning, you just install it with the small injector and off you go.

For you, the idea would be similar. Rather than running a medium injector and tuning for it, you could also use the small injector and keep your same track tune. Daily driving you'd turn it off. On track days, you fill the reservoir and spray.

That is EXACTLY my plan, and the day I have a track day where I overheat during or before session 4, I'm buying water meth with intent to turn it on only during track days.

I shipped my car to Weistech for a month for them to go over and retune everything, including a transmission tune. Everything has been working great for some time now. I thought about meth, but really don't want that in my trunk, and I think it only adds about 30hp combined with what I have already. I took off my DP again and fully wrapped it, big difference. I can pretty much touch it now when hot with the lava wrap. The wrapped DP, removed engine cover, and running my heater while tracking seem to have fixed my heat issues, I now only get to about 228 on the oil, where before I was hitting up to 238.

Good stuff. I bet running the heater helps bigtime. If I ran Meth I would get 0 HP, just the temp crash. My plan would be to take the whole thing out of the trunk for daily driving, since there's track prep anyways, I bleed the brakes, etc.

Honestly I shouldn't spend a dime on the car and just spend on myself until I can match your lap times with 15% less power :)

I haven't done Thunderhill but Sonoma was very good. I drove with an org I will not drive with again as I did not care for the experience compared to SpeedSF. I like the ship Joe runs with SSF. Knowing what I do today, I will just run Sonoma with Joe.
