PB 1:35.97 at Autobahn South

Another day, another PB. It was a relatively cool day out at the track starting at 60 in the morning and up to about 80. The first session the previous session had someone drag oil halfway around the track so it was delayed. Then another breakdown in my session got it black flagged. I’m a little disappointed I didn’t have more time in the cool morning.

I had a few new upgrades. The new motor mounts provided more NVH, but I’m not sure what else. The shorty headers sounded cool, but my vmax didn’t really change. I think the car really needs a tune at this point however. The o2 was throwing some errors and the transition to closed to open loop operation was rough. The new ducts were a win. Oil temps were down 15F or so. A much more tolerable high 260’s to low 270’s. The coolant was down about 20F to around 208F. That’s barely what it runs at on the highway. Either way a big win in the cooling dept.

Brakes were acting a little weird. Fine on track where I’m braking with high rpm and closed throttle. Kinda soft at low rpm around the paddock. General googling is pointing at a leak in the booster or the hose to it. Threw a new set of ER1 pads on before the event.

I have a cam ready to go in when I have time. I’m looking to put minimal dollars into the ls1, so I have ls6 springs which are cheap as heck. A “truck” cam It’s really designed to max out the cheaper ls6 springs and the cam itself is inexpensive. While it’s open, a melling 10296 high flow, high pressure oil pump and a harmonic balancer. I’m hoping it’ll get me 50hp and keep the low end torque.

The new PB of 1:35.97. That’s fairly moving for Autobahn south. If you look at the Savage Geese leader board, that would put about what a f87 M2 or the new Nismo Z does on re71rs with a pro driver.

The best track battle of the day was with a ZL1. He obviously had a lot more power, but I’d reel him in on corners.

Jackie Ding and PhD racing was out there again. I chased the PhD Supra for a while.

I have another track day coming next weekend. My parents are coming into town and my dad wants to do a ride along with me. He’s never been on the track before so I need to make sure to video his reaction.

• Flip my tires on the rim. The outside edge is getting worn. I might get a few more track days out of them.
• Check into the brake booster. I have a few parts on order
• check and make sure I didn’t knock loose a hose somewhere with all the work I did on the car last weekend
