The car finished in 25th place despite having 9 drivers (a lot of driver changes...). And about half of them are rookies.

Its boss.

How long was that race? Seriously, that's some intense driving on that course. I was much more interested in watching the Chumpcars over the NASA series cars on the Main Track.

***lemons, not chump

Saturday was 10am-8pm
Sunday was noon-4:30pm

I believe for everything (fueling, driver changes) the car had to go into the paddock (e.g. not in the pit lane)

Endurance racing is a lot of fun.

I'm actually using the RaceLogic with Launch Control. It's a pretty amazing system. It's a little expensive and takes a bit of time to get dialed in but once you do it seems to work well. I haven't had the opportunity to use it in the rain yet, but assume that is where it will REALLY shine.

If anyone does decide to go with the RLTC let me know and I will be more than happy to help you with install and initial tuning.

my driveway is full of crap



Front driver tire has a flat spot. Office driveway was re-paved

2+2 = I need to do some launches to 'fix' the flat spot

nope, no idea who that is.

last night I fixed a current drain that was killing my battery. 65ma drain is apparently enough to kill the battery in a few days. turned out to be that I wired the oil temp gauge to an always-on 12v

Talked to Savington and bumped base fuel pressure to 60psi. Since DW300 maxes out at 100psi, that gives me 40psi of theoretical boost headroom. Realistically 30psi would be pushing it and that's what my boost cutoff is set to (no, I never reached that boost)

The idea behind higher fuel pressure is that ID1000s atomize better and flow more. However the pump flows less fuel at higher pressures, so there is definitely a certain sweet spot. For E85 I might have to lower the pressure a bit, we'll see.

With 60psi car idles waaaay better. Full 20" of vacuum vs 18" before. Everyone knows that 2" matters.

Swapped the flat spotted tire to the rear, doesn't vibrate anymore. Need to get aligned because car gets unstable at triple digits - it's scary
2nd gear still breaks traction, 3rd feels ok but baaaarely enough traction, 4th is great.
did two 5th gear pulls - **** my life its fast.

I'll dyno it for sure - don't know at what boost level, though.

I really want to redo the wiring. It's a mess. As a result of that mess, I pulled the EBC power wire and it's running on wastegate now (16psi). Woops.

Like any project car I have a list of things to do before I'm happy:
- Battery randomly dies from sitting after a while. I already found a parasitic drain - now the current drain is 1.5mA when it's sitting. Charged the battery last night. My "commute" is 1.5 miles so the battery doesn't charge during that time. Voltage while driving doesn't go above 13.6 or below 13.1
- A tire was flat spotted but I think I "fixed" by putting it in rear and doing 2nd gear pulls
- Need to bleed brakes again
- Need to align
- Dat wiring mess

lololo

Went for a drive, car pulls hard at 16psi. Duty Cycle hits 69% at redline
That's at 71psi absolute pressure (from fuel pressure sensor), 12.9v and a rich, rich 11.3 afr

Sounds like someone is gonna need to step up either running higher base pressure or bigger injectors.

We'll see. It will be a bigger pump that can sustain higher pressure, if anything.

I looked at the last dyno logs and at 400whp (26psi) I was at 75% duty and 300whp (16psi) was 60% duty. I'm 69% right now on 16psi, presumably at roughly same 300whp.

Try it out idling at 8:1 AFR on the gas scale and let me know what you think. Burns so good.

my afr sensor doesn't go that low. you mean E85 scale? My sensor can only read 0.68 to 1.36 lambda (10.0-20.0)
E85 also backfires like mad. Before it would be an occasional pop on gas, now it's pop pop pop BANG pop. Its kind of great.

Naw, I mean 8:1 on the gasoline scale. Just idle it long enough in the garage to get the full effect then fix the tune.
