Thanks guys and yeah pie cut pie cut pie cut is right haha, used to really like them when I didn't prep them as well, now I'm starting to get tired of prepping the damn things haha, seriously takes forever. And then my buddies wonder why I don't wanna use them on their exhausts haha

On a side note I've got some extra welding jobs coming up which should bring in some decent cash, may even push me close enough to vr-1's which I'm really thinking about getting. Couple of downpipes and mid pipes as well as a harness bar. We'll see, I do like the idea of actually learning some throttle control before getting some tires that give me grip.

ughh i had 205 Tire Rack Korean specials for street tires when i had 330whp,. 3rd gear, find the power band, and they would blister off. it was by far the scariest thing to ever experience was wheel spin at 65-80 mph in a straight line. do a good tire and it will actually behave. a fresh set of rs-3's on a hot day and i would actually hook in first. the thing was a blurry of speed when i had traction in first gear.

The only wheels I have lying around that fit over the brakes are either my gold 15x6's that were drift spares for brad previous owner, (I'll rattle can them silver if they go on Audrey at least) or the 15x10 6uls. Pretty much gives me a choice of **** tires or vr/rc-1. I suppose I could buy a decent set of 205's too but at that point I might as well just put the extra money towards one of the maxxis tires. I'd love to go with the rc1 but I think for now it might be better if I go with the vr1 since it's probably a little more forgiving. Still time to decide, tires are the last thing I'll be buying for the car.

Oh also, remember how I mentioned that both the oregon rally group and the local autox like to schedule events around my finals/midterms? Yeah, guess which organization scheduled their next event the weekend before my finals? BOTH! **** me. On the other hand I was gonna be in Utah anyway for our mars rover competition, but seriously??? Every event since october has been scheduled a day or two before a midterm or final, how did they even do that?

My friend's car had tires so old it would do that in the rain with maybe 130hp. I thought it was a hoot, but it would do it without pulling any particular way.

If you got a dollar for every cat I've given this thread........


you could buy gas to get home

I always appreciate cats! Midterm in my circuits class tomorrow so not a whole lot of work has gotten done but I'm hoping to spend pretty much all of tomorrow afternoon and friday on the car to get the exhaust finished being tacked. That way I can pull the engine back out this weekend, aiming for having it out by Saturday night. Then it's time to start painting the interior/engine bay and putting it back together for (let's hope) the last time! Also remembered if I get vr/rc-1 I'm gonna need rear flares at a very minimum, something else I need to think about as far as costs.

Had a good couple of days, currently taking a break from welding to grab a bite to eat. Got the exhaust all the way tacked up and started doing the welding today, going through a ton of gas welding this exhaust. Got a fupa 12 and man that thing is awesome, gobs of gas coverage and it's letting me really play around with how much heat I put into the weld, learning lots through this process. Also got my purging set up pretty dialed in, it's working really well now which is nice.

Also last night my old job was hosting a go karting night and one of my old coworkers who works in sales now got me in. It wasn't quite as much fun as last time because everyone was a lot slower so I ended up getting stuck in traffic a lot but I got the second fastest lap and won myself my first trophy as well as an autox with a Lamborghini or a Ferrari. Should be a good time.

Bring the LS3 miata to the auto-x and see if you can beat your time in a ferrari/lambo

i need a tig welder. i'm jelly of you. :P

Scaxx

I absolutely love the tig, hardly ever use mig anymore unless it's for stuff that's a pain to get to. Completely worth it to get one. And I was actually thinking about that, might be kinda fun to see how it measures up, especially since they'd both be driven by the same fool. Although that v10 screaming at 8000 rpm is what I'm really looking forward to more than anything.

Scaxx

I forgot to post photos of the finished product. Turned out alright, I still need to work on my consistency in my welds a lot but I was also experimenting with different amounts of heat and speed so that contributed to the welds not being that consistent. It was definitely lots of good experience, still getting everything nailed down though so lots of room for improvement. But the good thing is the insides of the welds came out nice and flat which is the important part. I went through about 2/3 a tank of gas welding all this because I had it purging the whole time so I need to go pick up some more gas today/soon.

I also machined a delrin bushing for the rear diff, still need to pick up some brass rod for the middle. Also had a really bad day yesterday, I had been working on these two stainless shift ***** for the past week and I had them pretty much perfect, I polished them to a mirror finish and they fit perfectly in my hand. I spent a ton of time getting a nice ball on the end of both of them and I don't know if anyone's ever done a ball on a manual lathe without a radius tool, but it's not exactly easy. Anyway, at the last second when I was parting them off the lathe decided to eat them both at the same time and destroyed the finish. I was pretty disappointed but I guess that's life for ya. Still haven't pulled the engine cause I'm doing little **** in the engine bay like getting the lower radiator hose situation figured out.

Last couple of days have been much better. Got a big *** tank of gas, doubled my old supply. Got my entire exhaust welded. I'll let the pictures talk.









Also went to an autox with one of my buddies and another buddy's little brother. My buddies little brother is about to turn 16 and he hunted down a clean s13 and bought it since he's been saving money for a while, thankfully he says he doesn't want to turn it into a drift car, so I'm trying to push him towards motorsports that don't reward you for running into walls. We were talking about how there probably wouldn't be any 240's there on the way to the race and what do you know, a bad *** 240 showed up on a trailer. I went and talked to the driver to see if he could give my buddy's little brother a ride and he was happy to, safe to say he really wants to get into the better side of motorsports now. My buddy has a really clean 2002 that he's spent years restoring and collecting little rare pieces for, but he's still not afraid to romp on it which is pretty cool. It's got a little work done to the suspension and some much nicer tires than I was on, but he's still a better driver so he beat me up pretty good. It was all good fun though, he's been riding dirt bikes and racing them for years so I kinda expected it. Here's a couple pics of the event. He's also got a 2000 touring (one of only a couple in the states) and an e30 325ix, also rare as ****. In fact if I remember right they're rarer than the e30 m3.

Looks like that exhaust should be nice and quiet.

Hey, I was considering going to that autocross yesterday, but I had just got back into town so I was feeling a bit lazy. BMP is only like 5-10 miles from my house. Are you going to try to go this weekend?

Scaxx

lol, definitely. I do have a couple ideas for keeping it quieter on track if I can't pass sound.

I wish, I'll be in Utah this weekend for the university rover challenge. I'll be at the one on the 19th though!

Itty

Nice. I'll plan on going to that one as well.

Scaxx

Awesome, I guess I'll see you there then.

Mars rover competition went really well today, the suspension that a guy and I designed performed flawlessly, we couldn't get the damping to work correctly, so that's something to work on next year but we placed in second for the preliminary rounds. Now we get split into the top 15 and lower 15 so even if we completely **** up we're still in the top 15. Seeing as how many of these teams have been here for 4 or 5 years we're all extremely proud of how well we're doing. A lot of the next two days depends on our science portion which is soil sample analysis, sadly one of our two sensors took a **** today which means we won't score as many points. We also have an astronaut assistance task and one other as well as another traversal task. We should kill the traversal, our rover pretty much flew through the traversal today like it was nothing. I'm hoping for anything under 10th overall, the fact that we even made it in the top 15 is awesome. We also beat the hell out of UW's (our rival school) rover so that was awesome.

I'll post some pictures when I get home next week, been pretty cool out here.

Scaxx

I realize that this isn't at all miata related but our rover has 4 wheels and suspension so it's close enough. If you don't care about how the competition went then this post will bore you

I told you the first day went well but we were a bit worried about the second day due to our soil analysis sensors not working correctly at the time. It was also a bigger deal than we realized to get into the top 15 teams, cause no first year team had done that in the competition's history. Second day we started out the day by taking a soil sample and dumping it into a sealed container on our rover, this sample would then be analyzed later and we would present the results to the judges. Anyway, next part of day one went worse than we had hoped. We had a very articulate claw that could spin things and turn things very well. The second task involved hooking a carabiner to a cart with a gas can on it, traveleing to a little station. Then you open the gas tank, poured the gas in, closed the gas tank, un-screwed a regulator and put it on another regulator socket thing. After this was all done you pressed a button on a panel and read the voltage output. Keep in mind that this is all done by a guy with a controller in a uhaul trailer and two cameras but no way to communicate with us outside or see the rover. Not exactly easy, but possible. Anyway at one point he scraped the claw against the battery box and it ended up shorting so we lost claw movement and lost a decent amount of points on tasks that we wouldn't have had problems doing.

So we were a little disheartened as we made our way back to town to present what we thought would be a sub-par soil analysis presentation. Turns out we were wrong, between the guy that got asked if he was a geology major and the guy that had been up for over 40 hours trying to get our sensors to work, we absolutely killed the presentation. The judges loved us and everything went better than expected. The next day was traversal, we **** all over that course. Didn't have any problem what so ever and scored a perfect 100 (one of only two teams to do that). The last task was astronaut assistance and it involved picking up tools and delivering them to astronauts in a 1 km radius. Our motors were still geared down from the previous task and although we couldn't get to all of them we ended up placing second in that task.

We ended up taking second in the competition and not only that but our main science guy got the science award for the year. Overall really cool experience and we scared the **** out of the reigning Polish champion since they are somewhat used to dominating the competition and a little satellite campus that no one has ever heard of just came in and kicked ***. I'd really like to get the damping to work correctly next year as I did see some oscillation in the suspension and that will only be increased at higher speeds since we're going to be moving to 24v and switching the gearing. But either way, it turned out really well and we're all really proud of how we did, especially since there were quite a few ivy leaugue schools in the competition. Here are some pictures from the competition.

Made some progress over the last couple days. Also been working on other people's cars to make some money cause I definitely need it. First thing I did was cut the rest of the bumper support out and then weld in a bar. Dropped a decent bit of weight, something like three or four lb off the nose of the car, it also clears the snorkel. I also welded two nuts flush with the radiator support so that it bolts right up, I had to cut a slight relief out of the support today to get it to sit all the way down but it turned out well. Then I welded the double slips to the front of the exhaust, now it just needs hangers. I also weighed it and the whole back half from headers back weighed in at 26 lb, I'll measure the headers as soon as the engine is off the car but I was happy with how the back half turned out.
