Default Few autoX vids of the Miotta.

So I finally got enough done to the car that it was autox...able. So I took it to a test and tune yesterday.




It was very fun to drive... a serious handful... but fun.
Of note...
4k+rpm vibration... still there (can't hear it in video though :( )
195 rt615s are NOT enough tire
I shouldn't be lazy and work harder on tire pressures
springs are too soft for my taste (coilovers in the mail)

I was about 4 seconds off FTD... and there were stock miatas on Rcomps faster than me.
Also realize... its the 2nd time I've ever pushed/driven hard a rwd car... the last time was 1.5yrs ago... and it was 100% stock

Anyways... as i said...it is a handful.

Without further ado... here is my last and "best" run
http://video.google.com/videoplay?do...07397870&hl=en

Here are the rest of them 3-9 (1/2 i hit wrong button on camera... dnfs anyways , 4 is also a dnf)
run 3 - http://video.google.com/videoplay?do...56140179&hl=en
run 4 - http://video.google.com/videoplay?do...47960876&hl=en
run 5 - http://video.google.com/videoplay?do...90658658&hl=en
run 6 - (never knew my voice sounded so aweful on video...) http://video.google.com/videoplay?do...87822258&hl=en
run 7 - http://video.google.com/videoplay?do...38856963&hl=en (up soon, google is slow)
run 8 - http://video.google.com/videoplay?do...95832016&hl=en
run 9 - http://video.google.com/videoplay?do...88542177&hl=en

Enjoy the first run out in the car. It didn't explode or burn or smoke... so it is almost a 100% success... 100% would have been it handling like I want... and having traction... and not vibrating above 4k rpm

Not sure i'd be classed in sm2 I suspect my vmount and lack of other crap tosses me into d-mod or something else silly like that. I'm not an autox'r though... i just need a place to test/debug/learn a bit before I get out on open track.

To each his own, I would bet on SM2 though. Unless you took out the interior, the v-mount itself doesn't exclude you nor do the holes.

I thought chassis modification would void sm2? It has the front bumper support cut out and tubular rollbar frame built below for the radiator mount. It is also a gutted dash.

Bumpers are parachutes. I poked holes in the parachute.

Cut bumper support and gutted dash bump you out of SM2. My guess would be XP. Not a fun place to be on street tires for sure.

I was wondering why your bumper cover hole looked so much bigger and cleaner than what I was able to do. Oh well.

Any empirical testing on the ventilated rear bumper cover? I melted the side of my current one running without the muffler on. I have a replacement that is more open, but haven't gotten around to putting it on yet. I do have a hole saw and am not afraid to use it. Anything I should watch out for?

I think that the car has to weigh over 2000 lbs to be in SM2.

I should weigh over 2k. It takes quite a bit to get a miata under 2k from my understanding.

No personal data on the bumper. Other than on drag cars... a lack of bumper or a holed bumper will see gains in trap speed due to the reduced drag.
That was enough for me. Plus I got the diffuser dress up plate in a trade... and figured why not

Yah, I'd be in one of the crazy classes. Thankfully I'm not an AutoX'r

Question for you. Custom vented hood? How have those vent positions worked for you? I'm back to thinking about more hood venting on my car.
This format....



I've just noticed a VERY warm/hot hood... and I am still undertrayless...

You can see the heat waves rising off the header at slow speeds. Not sure how much flow you get at speed. I have only pulled it out of the garage with the new extraction vent installed so I don't have any idea how it will effect things.


Side note: a 1.8L forced induction SM2 car must weigh 2247.8 lbs. Depending on how much fuel load I carry I am right there.
