Yep the hardware store. The ones here carry plywood, steel square tubing, carriage bolts, turnbuckles and eyelets, lawn edging, coroplast sign material, black paint, screws, etc. everything one needs to build a splitter.

Other useful stuff from the hardware store is aluminum tape, ducting, steel and aluminum plate, steel and aluminum tubing, all-thread, rivets, wire, zip ties, a decent selection of nuts and bolts, and fabrication supplies. I have spent many an hour wandering the aisles of Lowe's, with an evil plan in mind, piecing together the components I need to make it happen.

This picture was from the day we set the lap record at Buttonwillow 13CW (still stands). Cooler so we blocked off the rad opening to get a bit more downforce and cut some drag. The dive planes and splitter were made from corrugated plastic and .125 sheet ABS riveted together. The whole splitter and dive plane assembly were held on by 4 quick release pins for easier trailer loading. Splitter/dive plane thing weighed about 5 lbs. That's me driving in this shot. It would bow down on the ends at speed from downforce. Doing about 50mph at the apex of this slow turn.



wow. I had not seen how this car has developed. You mention you broke my CW13 buttonwillow record. what was the time and on what tires? Just curious. I shouldn't care, but its cool to see cars really pushing the envelope.

That was a year ago. 225//45 A6's, 230whp, ~2100lbs w/o driver. Did a high 1:55 later on NT01's. A few set up issues we didn't have time to play with but the car had a 1:54 on NT01's in it. Had the too small GTC-200 that day and was loose in Riverside, experimental diff tune, sticky throttle/tip-in hiccup, mushy brakes, low speed push and few other things I have forgotten. Nothing major but each of those little things cost a bit of time.

Honestly, that car was just barely scratching the surface of what we had planned. It's heavy, has a lot of rolling drag, never handled exactly right (very close though!), so-so brakes, and had "only" 230whp. Minimum maintenance and prep. William liked the fact that the car very cheap to build/run and preferred to keep it that way, I was focusing on other projects. We haven't done much of anything to the car since then really. Focused more on enduros and other stuff. That clip on splitter/canard set up went in the dumpster after being chewed up a bit in use. Car is being turned in a spare enduro car and S2 (normally aspirated SuperMiata). At TrackSpeed right now getting some prep work done and motor rebuilt.

In my head, I can piece together a sub 2000lb OGK with about 340whp that'll do 1:49's at BW13 CW on A6's. Pretty much every part is in my shop already, just haven't had the 100 or so hours needed to put it together. Hence the recent email thread about needing a tech/fabricator here for a few months..

Oh yeah, Eric "Red_5" has our onboard video & data from that lap. outside rear facing, outside front facing and interior, plus data overlay. Hopefully he'll have it all spliced together for us to look at soon.

so what is the new number now? I did low 55's my last time there, but sounds like that isn't good enough anymore. I wish the car didn't reside in TX as it got more developed. Made it pretty tough to get set up for BW. I won't give you the woulda coulda shoulda stories, but more time would have netted better results - i think just about everyone can say that.

sorry, wasn't being coy. I just needed to go find it.

1:55.127

It was during practice day before superlap 2009. I would need to dig for the datalogs that prove it. Officially recorded during the 2009 superlap was a 1:55.7. Unfortunate thing is that I had a lap that the AIM predictive lap time was a mid :54, but I got accidentally blocked in the S's by AFI's S2k. Car has never been on a tire other than the NT01. Car hasn't been back there since and really hasn't developed any since late 2008 or early 2009. As I said - coulda woulda shoulda. Everyone makes excuses and talks about what could happen if you could do it again. But it only counts if you can actually make it happen in my opinion.

Issue with my car is/was that the suspension worked really well at low speeds, but the aero loads became such at over 140mi/hr if you hit a big bump, like the ones that exist in the Riverside turn at BW the car would bottom and pitch the car sideways scrubbing a lot of speed. More spring and test time would have likely fixed it, but its all bench racing at this point. This in my opinion is the real art of making a fast aero car - how to design a car that handles in the slow stuff but can also handle the loads of high speed aero...

On those NT01's were you guys using a friction modifier? Can you post up aero shots of your car before you sold it? Did Andrew Brilliant do the aero?

Your 1:55.127 is fastest on NT01's AFAIK. 1:54.447 on A6's in Williams car.

cocky Andrew has stated he will be at 1:52s this year with NT01. fight is on to be the first to break 1:50 on A6. I predict under 1:50 either late 2011 or early 2012 (during winter).
my car was actually 2,200LB w/o driver.

From another post. This is the mold buck for the SuperMiata air dam. Designed more to cut drag than absolute downforce. No it's not for sale, just posting here to shared ideas.

I don't doubt it. Other platforms have progressed much faster than the miata has IMO. Andrew has some focus and determination. His youth allows him the time and focus I no longer have. I'm looking forward to seeing you guys push the limit.

As an aside, I know your focus has been spread to enduros too. When I get back to CA, I want to head out with you and have some fun.

will you be running enduro also ?
in my case, is like a Cold War Arms Race. US and Russia kept build more warheads till Russia lost. I lost the arms race somewhere around 280whp
so going to Enduro, easier picking there

meh. the winner is argueable. All I've got to show for it are a bunch of cheap plaques. I got bored with it frankily. Most fun I had in several years was getting beat by JC's S2000 by a couple tenths at buttonwillow and then by less than a 10th 3 days later at aaa. Moving sealed the deal i think. I'm not saying I became the USA in the cold war, but my budget definately reflects it.

As for enduro, yeah. w2w is way more fun. I don't own an enduro car, but am pretty interested in renting seats or bumming my way into rides. I was hooked after running the 25 a couple years ago.
