In-car video from the final TT group, Session 9, where I ran my best lap of the week!

My best lap was my first hot lap, once again, with a 2:05.579 - or 17 thousandths of a second back from Nagel! I stayed out and ran 3 hot laps in a row, which you can see bits and pieces of in the Speedcast video or in my in-car video, above. Nagel gave me the point right before the start-finish and I got a mostly clear track ahead of me for my first lap. I caught the TT2 Subaru again in Turn 4, T5 and was maybe held up a tick braking into T6, but he started pulling away from me after Turn 7. Watching my lap I was talking to myself and yelling at the car the whole time, might have left a few tenths out there, but I was on the ragged edge and tracking out to the curbing on most corners. When my lap timer said 2:05.59 after my first hot lap it was too close to call. So I went out in lap 2 looking for a tenth. I keep saying that on the video, "I just need a tenth... I just need a tenth!"

Exiting Witchcraft I pushed it a bit too hard and took the S-curves (attitudes) with a bit more curb than the car could handle and got it very crossed up. Kept it on track, barely, then cooled down for a couple of corners and went straight into hot lap 3. Tires were getting greasy and loose at the high speed corners in T2/T3/T4. Predictive timing was only showing low 2:06s and I was getting very, very frustrated. I needed to push it hard to find that tenth but could not afford to have an off. After 3 hot laps, where I noticed lap times slowing on each successive attempt, I packed it in, assuming I was probably only hundreds of a second slower than 3rd place.

We all got into Impound and they started weighing and dyno'ing a selection of cars. I was eventually weighed and was still 40 pounds heavy. Before they could finish with all of us, were told to leave our cars and head to the trophy ceremony.




NASA did a great job and each podium finisher in every racing class got champagne, a trophy, pictures with the Toyo Girls, and many of the contingency winnings were handed out right there. GoPro 3 Black edition cameras (just for running stickers), cases of Royal Purple, driving suits, and on and on. Time Trial had some of the more lucrative payouts, surprisingly. Mayfield had arm fulls of goodies and he had a smile a mile wide. Big congrats to him for the win and TT3 track record at Miller in his first time to NASA Nationals. It was close, with his final TT session 9 time dropping to a 2:03.052, and Smith in second only 3 tenths back at a 2:03.328 from earlier in the week. Nagel rounded out the podium in 3rd.

But the fat lady hadn't sung her song just yet. After the trophy ceremony we headed back to Impound and the cars awaiting dyno runs and weight checks stuck around until our cars were released. Mayfield's BMW dyno'd clean and went to load up. Nagel's white M3 got weighed and dyno'd since he was in the top 3, which was apparently that car's first trip onto the rollers all week. But it blew the claimed maximum power number on the dyno by nearly 10 whp. They did the 3 pulls and then his team argued about the shape of the dyno graph on one of the first pulls. So they pulled it around in line, got it up on the trailer, strapped it down and dyno'd it again, 3 more pulls. Ryan watched the second set of pulls and it failed again. Meanwhile I'm drinking a few beers and just hanging out at Impound, awaiting the outcome. Several TT directors met, they checked his most recent weight and dyno numbers, recalculated his class ratio, and it was also over the limit. Hmm....

The National TT Director Greg Greenbaum was busy with a protest and an appeal from another class entry (Super Touring Corvette) that took over an hour. After that was decided (it went all the way to an Executive Appeal and a NASA Board of Directors), he came to decide what to do with Nagel's dyno issues. Apparently since it blew both the dyno and ratio, all times back to a previous good dyno were to be thrown out. And since he didn't volunteer or have another a clean dyno earlier in the week, there was nothing to fall back on that was legal, so all of his times were tossed. If the ratio had still been good (power to weight) it would have just been a session DQ, which was already a DQ for the spin anyway, and he would have held onto 3rd. Greenbaum said "yep, he's DQ'd for the entire week, you are now 3rd place". Yep, just like that.

I talked to Nagel, and he was rather cool about it "Hey, I don't tune it, I just drive it". We shook hands, he congratulated me, then he went and got the 3rd place trophy out of his trailer and handed it to me. Man, that was rough - I felt so bad for him.... but not bad enough that I didn't take that trophy! Does an inherited win feel as good? Heck yes, when the cars were thousandths of a second apart and the other car didn't make dyno. We worked our asses off all year, and built a heck of a good TT3 car, that was both quick and legal. It was also a street legal car, with A/C, emissions, tags, interior, NAV/radio, the works. Weren't too many (any?) of those on the podium that week in any TT class. Probably for a reason!

While I was awaiting the Impound ruling, Amy, Ryan and Brandon had pulled the front end off, loaded up the car, got the 21 tires with only a qualifying run I scavenged from Hoosier's trash pile secured, and we rolled out for our 2 day/25 hour return trip around 6 pm, with Ryan and Brandon with us for the return trip. These Hoosier scrubs will keep us in R compounds for HPDE and test laps for months to come!



Wanted to give a shout out to our paddock mates from Minnesota. These guys are part of a ChumpCar team that were at Nationals to support one of their driver's, who ran some World Challenge races in the past and was now running a Honda Challenge Civic in PTC (should have been PTD - long story). These guys have been friends for years and were having a lot of fun. Photographer Brian Smyer was hanging around with this crew, too.

What Did We Learn At Nationals?

Reflecting back on this Nationals week, heck, this last year of running TT in NASA, we have learned a lot of lessons, and I'm sure we have many more to still learn. The experience of going to NASA Nationals was both informative and fun for our entire crew - and even the guys at the shop who didn't join us there. Coming home with a trophy was a good feeling, especially after starting the week off so slow and so far back (the car got 5.3 seconds faster from Thursday to Sunday).



Here are some of the little bits of wisdom that I humbly share with you after this Nationals experience:

• The power to weight ratios in TT's numbered classes are better explained in the ST rules. Most people were cheating themselves, running too much weight or too little power until the TT directors got us straightened out. Yes, even at Nationals, mistakes were often made on classing sheets.
• Don't run 40-60 pounds heavy for your class then complain if you lose by .017 seconds. In NASA, the power and weight matter a lot.
• Don't fear the dyno - get a dyno test done AT Nationals on the OFFICIAL dyno early in the week. Ask for a weight check early and often, too. You will want to have a good "tested legal" date to fall back on, in case a later test is blown.
• High altitude tracks can produce funky dyno numbers - be prepared to have to de-tune or add weight when the conditions are very different from your home track.
• There is no substitute for fresh race tires. Ever. The normal tire strategies we use at Regional NASA events (R6s for most of the laps, A6 for a single session and faster hot lap) can work well, but at Nationals we needed more sticker sets. Showing up on used or worn tires was a big mistake, as we were partially tuning around bad tires. Neal Roberts had taught us this. Economics got the better of us.
• Making huge changes to the car or set-up right before Nationals is a bad idea. Pick a time period a month or two before Nationals and LOCK DOWN YOUR SET-UP. Don't count on the 4 days of TT sessions to help fine tune the set-up, either.
• Don't skimp on your trailer tires. On an enclosed 2 or 3 axle trailer, bring two mounted spares plus at least a third unmounted spare trailer tire. Keep one spare + the axle lift ramp + a proper lug wrench right next to the trailer side door for easy access.
• Towing over the Rocky Mountains is the suck, no matter what vehicle you are using. Going "around" the mountains is easier than going over the worst passes. Plan your route accordingly. On the return trip we heard of some folks seeing ice on the roads on the difficult passes.
• If you are going to Nationals and have never run the track before, get there at least a day early to practice. Budget for this with time and tires.
• If you have doubts about fuel availability or quality at the track, bring your own fuel. We spent a small fortune on 100 octane race fuel to mix with the 91 octane "Premium" they use in Utah.
• When it comes to numbered TT classes (TTU/1/2/3), don't skimp on the aero. EVERY SINGLE top TT3 car had excellent wings, splitters, and low drag tricks. Nobody in TT3 used the "better" 9:1 optional ratio for using stock aero... every fast car took the weight hit to use aftermarket aero.
• Too much front downforce can be a bad thing (we've since made a 2nd splitter that is 4" shorter - see my next event write-up on how that worked).
• Don't do your aero set-up testing at a track that only has low speed corners (duh).
• High speed tracks require SERIOUS braking systems. Don't skimp, and "bigger is better" applies.
• Don't bring a street car to run in the top TT classes at Nationals and expect to win. It might work at a Region level, and it might have worked at Nationals in the past, but the top guys show up to Nationals in serious race cars.

I hope our mistakes and experiences can help you make the right choices for your TT build, if and when you decide to try your hand at this sport. And I hope reading our posts encourages that goal for most HPDE folks. Why? Because after a while just "running a DE" can get boring. There are not rules, times, or competition to drive you. Just "driving around a track" doesn't teach you much, once you have gone through instruction and are Solo'd. We've seen a lot of HPDE drivers moving towards TT, and I think that is great. But don't assume you have to go W2W racing after you get to TT. Many of us don't want or need the added risks, costs and damage potential that W2W racing has. If you can afford to write off your car after some asshat punts you off track and destroys your car, and that won't upset you too badly, then by all means... go right ahead. Because that can and does happen in W2W, but not in TT.


Hard Choices - Selling BOTH Mustangs?

Unfortunately we still need to sell the 2013 GT, and it has taken so long now that I'm forced to put the 2011 GT up for sale now, too. I know, that sucks - trust me, I don't want to do this. We had planned on selling the 2011 at the end of this year or in the Spring of 2014, to make room for the all new 2015 Mustang we want to buy, prep and race in 2014. That is still happening, but with so much $$$ tied up in both Mustangs, I need to move them sooner rather than later. We had hoped we could keep the red car for a while longer, but expanding the business needs cash right now and both of our S197 projects are going on the auction block. Look for an updated ad for the 2013 GT and a new for sale ad for the 2011 GT soon.

Since nobody made a serious offer on it, our black 2013 GT is getting taken back to stock very soon and will likely be sold on CraigsList to some random schmuck, as the "track ready" set-up didn't get me any legit buyers (just a couple of fast talking con men and a few low ball pranksters). Our red 2011 GT will be posted up as it sits in TT3 trim now, with the aero front end and one set of 18x12" wheels and tires. If that is a bust we'll put it back to nearly stock and sell it that way, too. Don't PM me about parts off of either car just yet, as I will ignore those straight off. When/if these cars have parts pulled off they will go for sale all at once and I'll post an ad here.


What's Next?

There are still a lot of events we might be able to squeeze in with the red 2011 GT. And who knows? Maybe the 2013 GT will sell and some other things will fall into place and we won't have to sell the red GT right away, and I can make all of these events (fingers crossed!). Here's what is on the race schedule for the next few weeks.

• NASA @ TWS on Sept 21-22 - we've completed this event and I will have the write-up shortly.
• Camaro Vs Mustang Battle on Oct 5 @ Texas Motorplex - sign up here. Vorshlag is putting together the autocross portion, so if you have a GM or Ford powered vehicle, please come out and join us. Only $45 to both autocross and drag race, and we will make sure it is going to be fun!
• Goodguys Lone Star Nationals Oct 4-6th @ TMS - We will go to this on Sunday Oct 6th for the Autocross (the last Optima Qualifier for 2013) in the red car on whatever street tires we can scrounge up. Any American built or American powered vehicle is eligible.
• SCCA Autocross @ TMS Road Course Oct 13 - if we still have the red Mustang by then we will run this event in that car. This is their once-a-year "road course" event, with the infield road course at Texas Motor Speedway lined with some cones and packed with a bunch of autocrossers. Walls beware!
• NASA @ ECR Nov 2-3 - Again, assuming we still have a TT3 car to race by then, we will be there trying to finish out the NASA Texas calendar with a 100% track record sweep in TT3 for 2013. We're 7 for 7 so far....

2015 Mustang for 2014 in... TT2?

So to recap a few of our 2014 plans, we plan on buying one of the all-new 2015 Mustang GT's as soon as it is available. From talking to a few key people that have sources at Ford, we think the new S550 chassis is going to be at least 100 pounds lighter. The Coyote 5.0 engine choice is assumed to carry over, and if it is like previous "chassis changes" it will likely have a small power bump, too. We will get the V8, manual transmission, and likely red again - but that's it. I'm not letting Amy pimp this one out with a bunch of options. So this means it will be even lighter and more powerful than the 2011 GT which we have been playing with in TT3, so we'd have to cork up the engine and/or slap on a bunch of extra weight to stay within the 9.5:1 pounds per hp ratio of TT3 class "with aero".

The next class up the Time Trials ladder is TT2, which has an 8:1 ratio. We have extrapolated that this S550 will likely end up there, once we upgrade the suspension, wheels/tires, and aero like we have the 2011 (and that will happen quickly). So TT2 is what we are shooting to run next year, again with a goal of developing new parts for this new Mustang chassis (S550), and hopefully racking up a few more NASA TT track records along the way. We haven't found a better venue to test new products for a car than the competition that NASA Time Trial provides. Unfortunately the NASA Texas the season starts in January, and the new car might not be out until April or May... and we had the TT3 regional championship for 2013 wrapped up by May of this year, so we can't wait that long to get a race car built.



Some of you may already know that Vorshlag is a lot more than just a "Mustang suspension shop". One of the many series of products we have developed over the years is our LS1 V8 swaps into various BMW chassis. We've done E30, E36, E46, Z3 BMW swaps and have kits for most of those, plus a V8 Miata kit that is under development. Our service shop has been cranking out a lot of BMW V8 swaps of late and I have a couple of E36 donor chassis at my house right now, without a clear purpose. So....

Vorshlag TT2/ST2 E36 Build Thread: http://www.vorshlag.com/forums/showthread.php?t=8254

Over the winter we will be building a TT2/ST2 BMW E36 LS1. The chassis is a white 1992 325is "E36 Coupe", with a tired motor and interior. This will be stripped down, caged, flared, painted and built into a W2W race car. We might briefly run it in TT2 before we sell it, too - that's my goal if we do end up selling the red 2011 GT before the new 2015 GT arrives.


Above: Our TT2/ST2 build is already underway with the BMW E36 chassis being stripped and readied for a cage

I know, its not a Mustang, but it will allow us to at least get in the class with something while we await the S550's introduction. We will also be building our E46 LS1 Alpha car with a 5.7L motor around TT1 class rules, also over the winter, which we plan to race and develop that kit with as well. The Alpha LS1 Miata that is moving forward (customer car), among other builds in our shop.



Don't worry - we're not done developing S197 parts, not hardly. Lots of S197 Mustang race prep, development and upgrades are still going on at Vorshlag on a daily basis. And we might be able to hang onto the red GT for a while, or if it is sold in "near stock form" I will look for a front damaged '11-14 GT as soon as we can and transfer over the front sheet metal and aero updates from this car, as well as some new shock and suspension options we are working on for this chassis.



So I hope this last series of posts wasn't too long and boring, and I apologize that my "Nationals Event Coverage" spanned so many days and too many words. I've already started my write-up for the TWS event on Sept 21-22nd, where the car again did very well. There was a host of updates done to the car before we took it to Texas World Speedway for this NASA race weekend, including a new "shorter" splitter which balanced out the aero imbalance we had at Miller. Our painter also reworked the hood and it looks top notch, but we lost the vinyl stripes in the process. I'll get that update posted shortly. Until next time...

Thanks for reading,
