I turned the boost table down a percent above 6k before this event, due to the 193kpa street pulls. Sunday morning in the 59F ambient I hit boost cut twice. Yay for a tank full avg 95 octane gas.
Working on vids now.
I am satisfied with my driving this weekend. Here's the tally:
Number of wheels off : ZERO.
Number of times I touched dirt: ZERO.
Apexes missed: > ZERO
And here's the part where this is miataturbo.net and I would be remiss for not reporting this. It's mandatory. Rides given to another man's wife that she will never forget: Where she says and I quote "Holy **** that was awesome"
"That was one of the best times I have ever had"
"We are totally turboing our miata"
"You are a badass"
Number of times that happened: ONE
And really, honestly, does that need to happen more than once? No.
Dan, Dana, good luck on your turbo build, hope to see you with the car at next year's event.
Here's the "sonofthehill" dual catch can diagram. Both cans are completely sealed with just 2 ports and the PCV valve must seal when blowing from the intake manifold to the valve cover. I recently bought a nice one from Napa but they seem to change often. The hot side can is optional and mine is not yet reinstalled, just a hose to my air filter for the moment.
Hmm. I don't have an easy way of plugging into my turbo intake. Not sure I want to. I'll PM more about this.
Here's my best lap, set first session Sat morning with Thumpett as ballast. There is much time to be gained, umm, everywhere? I was honestly quite surprised I did not better this time over the weekend. It's possible the RR's are on their last legs, as they were take offs when I got them 4 track days before this session. But there is much skill to be gained here for sure. Laguna is ... a ***** course. It's perhaps not super technical, but it requires *****. Mine got squeezed real hard a while back, so I have to work my way back. I feel ok with my progress. When this lap was run this was my 4th session ever at Laguna, with no right side coaching whatsoever, so I'm more than satisfied to have hit around the SM lap record in my car, on its first turbo weekend, with a passenger on board.
Trick to v-band ease while installing solo is to bolt the DP up to the catback first. That takes up most of the weight which lets you focus on flange alignment. I use a manual speed wrench for the v-band clamp (NO IMPACT GUNS).
I have a Milwaukee 1/4" battery impact I use for all the small stuff. Yes it's technically an impact but it's not very strong.
I think I will have to figure out something with a jack to support the downpipe. I'll try bolting it up at the bottom first but I'm not sure I'll be able to get it to completely mate up without it being free at the end. We will see.
Oil drain line now properly clears all the things. For anyone else who puts the bunghole in the preferred, engine out location, the line that comes with the oil/water lines will be totally unsuitable for you. It needs to be significantly shorter, it needs a 90 on the bottom, and it needs a 45 at the top.
This will allow it to clear the power steering and coolant in hoses without issue.
When having the hose built, you need to orient the 45 to the 90 either 45 or 90 degrees to the left. IE, if looking directly down the hose with the 90 at the bottom facing directly away from you, clock the 45 at the top so the fitting goes 45, up to 90, to the left.
After action report:
Intercooler driver's side mount to the AC condenser screw fitting lost its screw.
My 3m eraser wheel arrived, and I spent some time with on on Saturday removing the crud if the tape residue from the Tupperware. It did a pretty good job on that and I think it's a decent 10-footer now. The wheel didn't really touch the masking tape residue on the hardtop and the top of the windshield frame (for those that do not recall, this is from good intentions of he who stored the car until I returned from New Zealand, and didn't want a leak).
Since I'm going to paint the hardtop anyway, sanding will take car of it.
Overheard at the autocross:
e1_griego: "I thought you were faster."
Mobius: "So did I."
For the only event of the year, I had fun. RR's were mostly dead and never got over probably 100F despite my extreme tire-warming-by-overdriving-the-****-out-of-them skills. I have 4-minute-old 225 A7's for next year. Hopefully I can make more than one event lol.
Codrus starts talking about his dead O2 sensors, and I pull my car out of the garage yesterday for the first time since MRLS, and the gauge is blinking 7.4. Looks like mine has died also, and that I will be ordering the heat sink bung as well. I'll try a free air calibration tomorrow but it's likely the o2 sensor is now fried if it wasn't being powered since I put an hour on the car between yesterday and today.
In other news, finally put the suspension components into the Odyssey - new front struts, new rear shocks, and airbags for the back. The Odyssey (and every other minivan) really should come stock with an auto-levelling rear air suspension. You put the fambly, the dogs, the camping gear, and the bikes on the hitch rack on the car, and you're riding on the bumpstops. No ground clearance. It's dumb. The vehicle carries most cargo weight on the rear axle, and it has mushy assed springs that ride great when it's completely unloaded. Dumb.
But now I'm bagged, so I can fix that. Unloaded I'm running 20psi and it feels about right.
I ran a separate schraeder valve for each bag for 4 reasons:
a) fewer connections, so fewer leak points (4 vs 6 if I tee them together)
b) a leak compromises one bag, not two
c) I can pump one side higher if necessary, for asymmetric weight;
d) this is the biggest reason - roll control. With the bags independent, in a turn you get the increasing spring rate you want on the loaded side. If you connect them, the outside loaded bag just dumps air into the inside unloaded bag. It is, in effect, a pneumatic posi-sway bar. So separate bags for me.
Spring compressors suck. If I ever do this again, I'm going to rent two of them, because having a third clamp to use after you start clamping the first two would be awesome. In this instance, at least, I couldn't get the compressors around the topmost or bottommost coil, so I had to compress the hell out of the 3 inner coils to get them to unseat. Peasant labor!
