Yeah, but I'm not sure how much pressure I want to allow it to make at this point.

I spent today creating additional heat shielding out of aluminum plate. I did some yesterday as well. After a 30 minute drive, I'm very happy with the differences in heat between the hot and cold sides of the shielding. It is dramatic. When the intermittent showers stop, I'll get the pics.

Edit: Pictars!

The smaller shield has a 90* bend at the bottom and goes up under the heater hoses to protect them from underneath.

Note the slovenly downpipe action.

So now you have double failure points, the bolts and the vband?

V bands don't seem to fail when you take them on and off like turbine studs do, or did you hear the opposite at some point? I have another V band at the bottom of the downpipe, too. Maybe I'm just living life like a maniac.

Getting rid of that kink at the top of the dp will most likely yield you better heat results than those heat shields. Who's that dude that flipped his manifold to make a bottom mount and avoid that kink? Look up his build thread, you see what I mean.

I was referring to turbine studs backing of on top of worrying about the vband connection. I thought the main reason to go to vband is because theres no studs to worry about.

Your manifold looks like a week old dog-turd.

This makes me smile.

I was blessed with an oblong outlet on the turbo and couldn't weld a round V band directly to it. I did the V band for ease of service so I hopefully won't need to futz with the studs as often. I will be removing the downpipe soon to paint it the color of a week old dog turd.
Well, speaking of dog turds, how's your car running these days? lol
The pigment in that paint is 96% or so zinc as it is specifically for a "cold galvanizing" finish treatment. I'm thinking of doing the turbine housing and downpipe in it to prevent unsightly rust and other oxidation.

How are things with you? The lil' trucky doin' ok?

Eh, many of miata parts are gone, but the frames are still kicking around. I need them gone.

The machines shop is being useless about my VW head, he's had it over 2 months and can't seem to figure out how to cut the valve guides to set the seal depth.

I'm hung up on projects waiting on him. The paint, the engine, all that is waiting on my cylinder head. I was DEFINITELY going to take the VW to the mitty this year, but this set back has gone so ridiculously over the time budget, I'm wondering if that'll happen.

I get all my parts really high temp ceramic coated for the reasons you mentioned. I'm doing great. Helicopter training is REALLY cool, way better than primary. My grades are kicking serious ass as well. I think I found my groove.

The truck is awesome. Changed the oil, it hasn't used a drop. Not a peep out of the thing. I'm going to reward it with a timing belt change soon, but I want to get that damn VW on the road incase things go bat country like they always seem to. It's only got 123,000 atm. Machine shop promised me tomorrow... :party:

Meh, drive the 4Runner to the Mitty.

Making it is not a question. I just wanted to take a sporty type car I built.

More heat management added.

I made a test video with the gopro in the bumper mouth in preparation for track day tomorrow. I will also mount in inside the car some.






Finally created youtube acct as well.

How...do you not have a youtube account? I thought that thing was essential now days.

I don't live my life one Facebook notification at a time either. I checked it 0 times in the last 30 days. Private life is private. Everyone I know doesn't need to know everything I do. I'm not doing anything wrong, but I'm also not doing it for them.

That video perspective is going to be cool on the track. Can't wait to see it.

Better video the FailFlora has ever made.

I demand to know everything you do at all points in time. Anything less then that is unacceptable.

Then he needs a twitter account, not a facebook. :bowrofl:

Successfully campaigned the Slow Torture™ turbo Miata at Sebring International Raceway all weekend long without mechanical failure.

On track videos were taken, cars were passed, turbos sang, exhausts bellowed, tires squealed... innocent dirt got plowed...

Videos will be uploaded to youtube as soon as I'm able. And yes, I passed the Ferrari 599 but it was anticlimactic because he was an ancient old dude who didn't know how to drive.

Yay, videos!

This was the second session on Saturday morning. I had just swapped wheels between sessions and these skinny 5yr old 14" RS2s on stock wheels were overinflated and got very slick as they heated up. I was very inconsistent and was relearning the track since it had been 6 months since I was there last. And I also needed to settle my nerves. The car was so much different with the turbo and the suspension changes that there was a big learning curve on where to brake as well. I did much better in subsequent sessions.

I almost lost it overcooking the braking zone out of the back stretch into 17. The car had a lot more speed than it ever did before but the same amount of brakes and tires. I went two wheels off in turn 3 overcooking it just after that on those slippery tires. I had to go explain myself to "the man" after that.

More videos to follow as I get them uploaded.

Director's note - Camera was moved around to try different angles throughout the weekend. This one is inside the mouth of the bumper.

That is pretty awesome.

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!

Third session Sunday was much better. I was hitting my marks most turns. I still have a tendency to turn in slightly early when following another car sometimes.

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.

You going to bring the miata up to the Mitty?

I'm probably not going. I've got too much happening right now.

But but but... NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Is there any other way?

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.

Update:
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:

Must post video of wadding... have fun!

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

Alright, Jake and I are here.

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.



Technical question:
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!

why still use brace?

I read on here a couple of years ago that people had problems if they removed them. I'd love to be rid of it if safe to do so.

Can you comment on the hot lean boost question?

opinion on the eBay sandwich plate?

What ebay sandwhich plate?

>>>

Delicious. I'll see if I can find the exact one I bought.

Here's the same exact part, different chinese seller. It fit just fine.

you forgot the link bro

I am using the glowshift sandwich plate with -10an fittings. Mine works fine now. Just make sure when you install all the fittings to use locktight liquid sealant on them all and crank them as tight as humanly ------- possible.

just gonna use a breaker bar and stand on that bitch

Nice meeting you Steven! :bigtu:

On AN fittings? Is the quality of the ebay stuff that bad?

Actually ebay stuff isn't AN, so they won't work with off the shelf AN fittings, which you're not supposed to use any type of sealant on the threads for, since they don't seal.

I believe he's referring to the NPT threads in the plate, which you thread AN-NPT adapters in to.

Curly is correct. I mean use sealant on the NPT side that threads into the plate.

Yep, I did.

http://www.ebay.com/itm/UNIVERSAL-ALUMINUM-OIL-FILTER-SANDWICH-PLATE-ADAPTER-1-8-NPT-10AN-OIL-COOLER-BL-/200760223465?fits=Model:Miata&hash=item2ebe3de6e9& item=200760223465&pt=Motors_Car_Truck_Parts_Access ories&vxp=mtr

It rook rike dis:

And the larger fittings were equipped with rubber washers that did not require being gorilla tight, just pretty tight. You don't want to squeeze out or cut the rubber washer. The little ones I am not currently using were sealed with high temp RTV and installed reasonably tightly.

Here is the video from the second session taken from the bumper mouth:

Post trackday inspection reveals broken turbo to manifold stud. Unable to extract stud from down in hole and the drilling was a cluster due to broken bits. Buggered hole will likely require 10mm stud after all this. Yay! So much fun.

I replaced the broken shifter bushings and everything else in there too. Much tighter, much better.

I replaced the broken speedo cable today, also.

Wait were you not using inconel studs?

Not yet. I frankly didn't think that running 6-8psi on the track was going to make enough heat and strain to do them in. Apparently the high MAT correction in the MS1 causing it to pull fuel and lean out the mixture in boost makes EGTs go through the effing roof. Somewhere in the MS code it should be written "Thou shalt not run 13.5 AFRs in boost on a hot track day in Miami when thine AITs be 115*F". This is especially frustrating when it was street tuned to run between 11 and 12.2 AFRs in that same boost range with AITs around 92*F.

My cheap Chinese turbo blanket has somewhat disintegrated after being subjected to the high heat as well. What is left of it is crunchy when you touch it.

TSK TSK TSK. I would not even think of going out on track without the inconel even if you are slow as balls. Time to upgrade to TSE studs.

Dey's up to a hunert fiddy five bucs plus frayt now. Steeeeep climbin', dat.

How much is loosing time on track because your turbo falls off?

Turbo leprosy?

Is denial considered a legitimate form of treatment?

I've got 'one' good $37.50 TSE stud with fastener I'll send to you fer free because I pity you, fool... :)

This way you'll be sure the churbo doesn't come ALL the way off when the others pop :loser:

That's a nice offer, thanks, but I'm going a different route. Would you happen to have a lil' bit of extra Resbond, though?
