dunno know why 2 wheels off makes you go explain yourself?? Thought the rules was a spin or 4 wheels off... we need to get you in DE4 so you can pass them non-PB bastards at will!
At my track days a dropped wheel is nothing, two is a furled black flag saying "don't do that again". A second set of dropped wheels is a waving black to be talked to in the pits, more than that and they start considering if you should be let out on track again.
Internal wastegate flapper arm has become tight at certain amounts of opening and hard to open and close through full range of motion. Kinda feels crusty like it is rusty or carbon is binding it somehow. I worked it back and forth some and it helped a bit. I'm not keen on it. I'm pretty sure there is no way to lubricate it that would survive the heat. Am I alone in having this ever occur?
I guess I will try to work it to free it up some more so it flops easily like when it was new. It might be that the heat cycling caused it to relax and take a set now.
Ebay oil filter adapter spacer added to run lines to external oil cooler. This required "clearancing" of the intake manifold support brace so that the oil filter could be reinstalled. I removed the brace and cut a notch in it with a sawzall.
I had oil cooler lines built at the local hydraulic hose shop. I was planning on using a thermostatically controlled 2nd gen RX7 oil cooler but was unable due to fitment issues with present component layout. The A/C dryer and some of the bumper bracing prohibited two preferred locations. At some later date it may be added. Instead, I implemented an engine oil cooler from a Lotus 907 engine (2 liter, all aluminum, 8k RPM engine). The engine originally came in the Lotus Esprit and the Jensen Healey roadster, the latter being the donor for this cooler.
The cooler is about 10"x6"x2" and is mounted laying horizontally above and in front of the steel beam above the bumper mouth opening (pretty much where Hustler has his, iirc). With the fans on, I could put my hand way up in the bumper mouth and feel a significant amount of warm air being pulled out of the top of this cooler, so the placement seems effective.
I have a track day tomorrow at Homestead Miami Speedway and the configuration will be unusual. Due to track maintenance we will utilize the high banks of NASCAR's turns three and four as well as the front and back straights of the big oval. It should be really fast. I hope I don't wad the car up into a little ball. Here is the course as we will be running it:

Definitely in for the vids! Still no leaks I take it? I gotta head over there again so I can ride in your car. Were you still interested in that autocross on June 2nd with the corvette club?
No leaks yet but I wouldn't be surprised. Videos will be taken!
The autocross is still on my "to do" list for now.
I will be trying out a new tire this Saturday and I hope it isn't too sticky for my spring rates. I picked up some 205/50/15 Hoosier R6 (SM6) Spec Miata take-offs. I may need to increase my ride height slightly to allow more suspension compression distance during cornering to compensate. I don't want to be on the bump stops in the turns because the tires are so sticky. And I still have my old flat spotted 14" RS2's if I need them.
Buffon, Viperormiata and few others have threatened to show up so we may have some pics of the SFL crew with me tomorrow. I'm looking forward to meeting them.
That looks like it is gonna be amazing. The speeds on those high bank turns will be crazy. Hopefully noone gets too zelous and hits a wall. Of course, if that were to happen and you got it on tape you would be obligated to share the carnage. I need to get my larger intercooler and 6 point rollbar on so I can get out to some tracks. <---- envious
Blammo! Here's a video of the third session. The fourth session was not recorded due to operator error.
In the fourth session I learned I could flat foot it all the way around the banking. I am running Hoosier R6 SM6 205/50/15's for the first time.
The red rx7 was caged, had a fuel cell, and a strong v8. The black vette was fast but I also lifted when I gave him the point because that straight is short. He probably didn't need me to lift. The red M3 toward the end was on DOT slicks and was no joke.
My plastic shifter bushing broke and got sloppy in the second session so I was taking it kinda easy trying to make sure I didn't miss. Granny shifting FTW! Missed the shift passing the silver 350z.
The car was leaner in boost in the heat than in road testing and tuning. I have compensated for hot idle leanness with the IAT/CLT compensation. In studying the problem I have read references in threads about a MAT correction for high IAT's (or AIT's) but can't seem to find the actual fix for the MS1. Does anyone know what I am talking about and can direct me to it? I don't think turning on EGO correction is going to be the answer. I wish I had strapped a laptop in the car to datalog what was going on...
Many thanks to Jake and Jonathan for coming out to meet and support me. It was good to meet you guys. I hope you liked my budget track beater!
