They're nuts. Truck nuts.

I would say it's gotta be exhaust.

Just a couple new pics of the ride. Getting things ready for Spring Nationals.

And a couple Videos from the Blytheville Pro

Bada$$.

What height did you set your splitter to? Mine's at ~2.5"...seems like it hasn't scraped much (yet)...

There was talk of the 15x9 vs 15x10 vs 51x11's. Here is a pic of 10's on the left and 9's on the right.

May I please have permission to repost some of your cars pics?

Cheers,

As long as you tell me where and send me links :)

Black car finished 1st and 3rd at the Wilmington Pro. Here are Randalls last set and my last set of runs

holy crap. Those look almost comically sped up compared to my runs. I almost expected to hear yakety sax played over it.

I always get a kick out of watching your videos, the siren-like whining at the start gets me every time.

www.facebook.com/nitrodann ok?

Just want to show people.

No worries Dan

Thankyou, I will PM you when I do. I also love The Pass' car.

Haaa. Yea. I get about as many comments on the sound of the car on the two step as I do anything else. :) it does sound pretty bad ass in person :)

It's funny you would say that. One of my competitors asked me if I had sped up my videos.

I took some in car vidios with my cell phone and image stabilization turned on. it makes coming off the corners look like you hit the warp drive switch. its like trying to hold image steady when you slow down for the corners then catches up on the straight. keep in mind Spec Miata lap record was like 1:41.8 and I turned a 1:27.5 so it is sort of like that anyway without added distortion.

I don't think you did that, I just know that I drove that same course really slowly because I sucked/suck.:facepalm:

Looking forward to the Toledo Pro Solo this weekend. If you are at the event or in the area....drop by and say "Hi"

I'll be there! and I'll make sure I stop over.

Good deal. Looking forward to it.

Awesome of you to stop by the trailer today Zach.

Hope you do well this weekend.

Dude, WTF kinda rocket juice is Davis on in CSP? The Devens performance was supposedly course dependent so I heard. But this?

Thanks Eric! It was really great to meet you and get a better insight into just how balls-out insane your car really is! Watching it on course on Sunday was just something else entirely. Congrats to you and Randall for taking the 1st and 3rd trophy spots in SSM for the weekend!

I had a rough weekend - wrong car, wrong tires, etc. but I had a ton of fun so it's all good (except for the cold rain monsoon on saturday)!

The rocket juice is called a Billy, he does have a CSP national championship, and that does mean a bit more than a jacket in some other classes.

Great seeing you again eric, thanks again for like the 11th time letting me hop in your car for the challenge after I blew up 2nd gear again, fuck that thing accelerates like holymoly.

No worries at all man. Good seeing you again too and congrats on the Trophy.

What do you mean it accelerates like "holymoly"???? It's just a little stupercharger car :)

Hope you get your car fixed and look forward to seeing you in Wilmington in a few weeks.

There's a 6 speed sitting in my garage and the last Mazdamotorsports 3.63 in the country in the mail to me already. ;)

SWEET. It's about time you got that thing "Turnt up"

6 speed 3.636 is a decent combo ill break about 10 5 speeds for every one 6 speed using it for autocross. I was shocked to loose about 12 lbs with the 5 speed Quaife however. Even lighter now that big side of my 5th gear is ground down to nothing more than a spacer sleeve. less rotating mass. Most of the weight difference between the 5 and 6 speed is rotating assembly parts.

A Couple YouTube Vids from this weekends festivities in Toledo

Check out the % of time we spend loaded up over 1.5g. No wonder we were so out of breath when we got out of the car after every run.

Car was pretty good at the Wilmington Summer Pro. I drove well...just red lit away a time that would have landed me in second place....then coned away a time that would have....you guessed it.....landed me in second place. We were the fastest thing there with fenders. Only vehicles in the 31's were my car and 2 of the shifter carts.

Had both these runs been clean, I would have been 2ths out of the lead and solidly in the challenge. As it stands....my co-driver won by over a second.

This is what you missed if you didn't make it to the Wilmington Champ Tour.

Is that your car in the background? September issue of Sports Car, page 7.

https://www.miataturbo.net/attachmen...ine=1440115584

Yes. And it's also in the "Pick to Win" section.

Fastest Miata at Nationals second year in a row :)

On a side note. I need to find the best cylinder head builder in the US. I need to send him some parts for a post mortum. Those of you who were at Nationals know all about my issues....when I got the head off the car today....it was A LOT worse than I had expected. We are REALLY lucky the damn thing didn't fly apart on Randall's last run.

Pics will follow

Did you wear the lobes off the cam?

All I know is that his intake valve clearance closed way up. He can say more. I'm too afraid to look at my intake valve clearance or my oil after the amount of time my car spent banging off the 8500 rev limit on the plane side course.

Need 3.3 rear end?

Oh, well that's a valve/seat issue then. I'd be curious what seat width he was running on the intakes, and where the seat was making contact on the face of the valve (outer edge, middle, inner edge). That's likely the problem if the intake valves are tightening up.

Since everything is getting changed for next year. I'll do something I have NEVER done before.

Here is an old dyno graph....

https://www.miataturbo.net/attachmen...ine=1448585108

Oooh. I like that torque curve.

Eric, is that your before-cams motor or after-cams motor?

I don't remember.

But then again.....everything is getting changed this winter. New blower, new head, new short block, new fuel system......Like literally.....everything.

https://www.miataturbo.net/attachmen...ine=1448587289

Ooh fun. What details can you share. Same blower? Something besides a VVT head?

that is one really stout powerband, very nice

I know a little about it, not sure I can post it though. Not a VVT head though I know that. But now you see why I'm trying to get my whipple setup working correctly. :)

Yea, I'm not posting any specific details about the new setup. Sorry :(

The car won the Pro Solo Championship by a healthy margin and finished 3rd at Nationals only .094 second out of first, with 1 cylinder over 80psi down on compression.

So I'm hoping to make it better, stronger and faster this winter.

Is some of this David's old set up?

No

holy flat torque curve! I needed a 4.778 rear end and 8600 rev limit to avoid shifting and to attempt staying in my torque band for coming off corners.

https://www.miataturbo.net/attachmen...4&d=1448689560

Bob if the courses keep going the way they're going you might just want the 4.3 and my turbo. I needed about 8 more mph without otherwise changing my car to be happy on the plane side course.

8 more MPH???? Does your car go less than 70 as it is?

Sixty Nine, very nice.
https://www.miataturbo.net/attachmen...ine=1448766020

Haaaaaa.

At 8600 rpm my car would do ~73 MPH in second a 6 speed with a 3.636 would do ~71. It's well off the end of my power curve however but it will go that fast. The problem was the Plane side course had pretty much no slow spots it really wasnt much of a power course CSP cars would have been towards the front of SSM on that course. I was going to try 3rd gear on my second run because the Quaife is close between second and third it would have still been on torque for all but one turn. Broken throttle spring on a Skunk 2 throttle body DNF'd that run however at the first lift spot. With the mad rush and panic to re-bend the throttle spring and make it work to get my last run I decided to not try it again. Last run was fast but with one too sideways moment that probably cost me 3 spots in the trophies. Didn't actually hit the rev limiter but a lot of time was spent deep in the revs past the sweet spot of my power curve.

The run where I nailed the first turn around I was on the rev limiter at the first offset coming back towards the stands. After the turn around by the stands I was take it or leave it on the higher rev limiter and I think if I ever could have gotten the turn correct in the back left corner of the course I'd have been on the limiter on the back section longer than the "straight" too. But yeah that course was a whole lot of drive my car like its in CSP, floor it and turn the wheel and brake for the pin turns.

I think Erics flat torque curve would be easier to drive. my car becomes more driveable only by gearing it to stay away from the rapid torque rise portion of the curve. I have no traction control ABS or launch control. Eric has all of that. Need to come off slow corners at about 4000 rpm or better or throttle control is much more like the throttle cable is a sticky stretchy rubber band. Having said that I think the area under the used portions of our two curves arn't that much different. If I drove my car on a road course track for 20 minute sessions with the boost turned up like that it might not live much longer than his but if I turn it down about 50-60 hp it's reasonably reliable.
