Summit Point 7-14-08
Jul 27, 2008

2 weeks ago, I visited Summit Point, WV to participate in a 2 day DE with TrackDaze. This is another great club to drive with and another great track to add to my cap of driving experiences. To date, this is my favorite track. TrackDaze offered (4) 30 minute sessions per day which is a great value. Summit Point offered a new challenge with both low and high speed turns. Throughout the 2 day event, I became more comfortable with the track, my car, and driving in close proximity to NASA racers who are much, much more experienced than me. This was my 6th track day, 3rd in the Mazda.

Day 1, Session 1
I used this is as an exploritory session. Where are the turns and braking points? Who are the quick guys? I was running in the black run group which is the same as advanced or HPDE3 in other clubs. I could see immediately there were others more familiar with the track and DE driving in general. Many were NASA or SCCA racers.

I started off slow using 2nd gear in turns 1 and 5. My car was suffering a bit showing water temps at 210. It was a bloody hot day at 95. A black flag came out for a stranded car just off the racing line so all came in to pit. I turned off the car (I don't have a fan) to prevent the car from overheating. Once started and back on track, the engine temps had hit 220 and were climbing. I tried to cool by running quick and getting out of line, but it continued to climb and make strange noises. I pulled in and nursed the car to the paddock. The water temp was at 240 when I shut it down. Fluid emerged from the overflow to release some of the pressure. I run water and water wetter, not coolant. After lifting the hood, I noticed the steering rack boot had melted. I thought that was quite strange.

After talking to my mechanic we determined it was a turbo exhaust leak. The gasket between the turbo and manifold had blown out. To keep it alive throughout the day, I drained some fluid, added coolant and tightend down the turbo the best I could. He also said "stop using 2nd gear and drive faster. If you drive faster, the car will keep cooler". Sounds like good advice to me.

Day 1, Session 2
The car sounded better and temps ran cooler throughout the first 10 minutes. Later, the exhaust leak returned and temps started to climb again. I backed down my shift point to 7000 RPM and broke out of line when following in straight sections. This stabilized the temps to 220, but the car sounded aweful. I thought to myself... "I'm just gonna drive the thing. I didn't drive 400 miles and take time off work to nurse this car around. I'm gonna drive the wheels off it and hope it holds together".

Day 1, Session 3
I followed my buddy Gabe in his 2004 Evo MR the entire session to get him on film. It's great to see the differences in the 2 cars. He has quite a bit more power than me, but I'm close to 1000lbs lighter. He could scoot away on corner exits with AWD power and I carried much more speed throughout the corner (entry, apex, and exit). Following closely though took a toll on the engine temps. Upon pulling into the paddock, I saw the lower radiator hose had burst. This is why I don't like to run coolant on track. If it burst on track, I (and others) would be sliding on the coolant. Luckily, it didn't burst till I parked it.

Day 1, Session 4
I relaxed. The car was broken.

Day 2, Session 1
With a paddock repair to the radiator hose, another cinching on the turbo bolts and a good nights rest, I was ready to go. It was even hotter today than it was yesterday. I looked at my timer to reveal 114 cockpit temp on my 2nd session. Throughout this session, I started to push just a little harder into the turns, a little deeper in brake zones and my lap times started to come down. This caused higher corner exit speeds and forced me to shift at different points and ultimately use higher gears in some turns. This created yet another new learning experience.

Day 2, Session 2
I continued to push a bit harder by braking deeper and carrying more speed in the corners. About 10 minutes in, I find NASA racer Eric Wong dicing with an M3. Eric is one of the top drivers in GTS3 and GTS2 in the Mid-Atlantic region. Some kind of instinct kicked in that made me push even harder to try to keep pace with these guys. I ended up turning my fastest lap during this session, but it wasn't the smoothest bunch of laps. The last session was almost as quick, but much smoother. I did get fairly close, but I know Eric was in GTS2 setup and wasn't driving to his full potential. He later drove off into the sunset. One of these days, I'll run toe to toe with him.

Later in the session I felt a stumble in the car. At first I thought it was another mechanical failure, but the next lap, I realized I was out of fuel. I don't have a fuel gage so I must learn how much gas this thing uses or get scales. I pulled in, added 10 gallons, but the session was over before I finished.

Day 2, Session 3
I followed my buddy Gabe in the Evo MR the first half of the session. After breaking way, I continued to explore braking points and corner speed. At 1 point, I carried too much corner entry speed at turn 5 and drifted the rear of the car throughout the corner. It was a bit of a moment, but I held onto it.

Day 2, Session 4
I'm continuing to get quicker and more comfortable. I'm also getting tired at this point. 30 minute sessions take a lot out of you; especially in this heat. Others must be too. Numerous participants had left at this point so the Advanced and Instructor groups were combined. Towards the end of the session, I got the feeling like I'm starting to figure this thing out. The driving part that is. I ran out of gas again. 10 gallons doesn't last 1 hr.

Day 2, Session 5
Bonus session with advanced and instructor groups combined. This was far and away my best session. I ran most of my laps in the 28, 29 range with my fastest @ 1:28.83. I got the opportunity to run in very close proximity to NASA racers (spec e30, H2 Integra, CMC Mustang, GTS3 M3, etc...) It was a great experience that I learned a lot from. These guys really drive quite a bit harder than I do. They brake very late in the brake zones and carry more speed in the turns than I expected. The Mustang and e30 were very tough to pass. I couldn't shake the Integra. I tried a bit too hard going into turn 5 to get a good run through the carosel. This was the tight, twisty part of the track where I was quick. I entered turn 5 too hot and looped it facing the wrong way. All the cars I worked to get by paraded on through. Wish I had it on film, but I ran out of memory.

Next event is Lime Rock Park with SCDA on 8/13. There will be some very nice cars there. I'll try to get some video of me passing a GT3 or Ferrari or something exotic like that. Somehow, I don't think it will measure up to running with NASA racers though.

Good videos Mike, enjoyed comparing the real to that other sim, very very similar even the road surface and tendancy for oversteer on the broken up slow left hander T5.

What is terminal velocity at the end of the front straight?

Car seems well sorted chassis wise, you didn't have to work the wheel much.

Looks like I'm going to ButtonWillow (CA) on the 10th for some TT in the Lotus Challenge Series. It's a two day event, but I don't have the time to do both days, besides I've done BW some many times I really don't need two full days to practice for the TT -- which apparently is going to be at 5pm - 6pm and Loti only.

Still signed up for Thunderhill 23/24 but I'd love to get out your way and do some of those tracks. I mean you have green grass and trees!! CA tracks this time of year are brown, golden brown, dust, dirt, maybe more brown, tumble weeds, and some more dirt with a few hills and our choice of temps are somewhere between 90-120 (in the shade, not track temp). I envy you and those lush green tracks.

P.S. - don't you dare sell the GT3.

He knows how to drive to!!! Nice vid. To see that BMW at 3:28 mark come flying across screen is an eye opener. Was not expecting that. It could of been ugly

My mechanic is also an ex Speed World Challenge driver - Hugh Stewart. He knows how to setup a car.

LOL Strictly driver only!!!! Love it. Get your hands dirty Mike!!!! It's the only way your learn to tweak the car to your liking. You can only communicate so much...

Thanks for offering Bob, but I don't like to work on the car. My mechanic gets parts from somewhere.

Where ya getting the replacement turbo gasket and related parts? Anything I can help with Mike? Obviously, you get the CT discount :)

Mike - The event is only a one day event, with 4 sessions I believe. It's on a Friday with the IT*Spectacular race following, for all the ITx cars, on Saturday and Sunday. Since my car is prepared for STS2, I'm going run street tires anyway, but I may have access to some Spec Miata tires (Toyo RA1s). But right now I have some Falken Azenis that are shaved that came with the car at about 4 or 3/32nds.

Yea Mike, I Do agree NASA has better classing structure. i just want my car to be able to cross over viceversa. because i can make it to SCCA club events in 3 hours and run a series, NASA`s are 6-12 ours to follow a series..

Justin - the track was a mess in turns 1, 5 & 6. The surface is broken up quite a bit. You can see the car shake violently in the video. The track was repaved last fall. I'm sure they will add concrete patches again soon.

Rob - there is some video now of sessions 3 & 4. I'll add more later this week. Enjoy your drive. I look forward to your write up and video. I'm not going to make it out to California to drive with you, Tim and Connor. Maybe some other time. Costs are just getting out of control. My R888's will likely be toast by the end of LRP. I'm already driving on them in the wrong direction. That is ok as long as it doesn't rain.

I was just testing at Summit point ... errr ... simulated ... on that "other" service. Simulated track is awesome - love it.

Mike NASA and SCCA were at one point talking about becoming "one", but it was a situation where SCCA would just take control for the most part (the larger organization that gets TV coverage).

What your Mazda is coming apart already ;) hehe

Mike, I'd expect you to be fast and put in some good lap times, in "most cases" (not all) good simulated racers make good real life racers where the only things to be learned is how to race, how to preserve the equipment, and how to drive as fast offline as online.

Good to see you doing these events. I might be at Button Willow (SoCal well actually Mid Cal) August 9th/10th and for sure at Thunderhill August 23/24 -- with video of course. Would love to see your video.

But then like Mario used to say, the brakes are for a lot more than just slowing the car down. ;)

Good story and nice footage. The track surface there looks pretty daunting through a couple corners (5 and 6 I am guessing). Must be good times.

Tom, You are going to have an incredible time at Mid-Ohio. What a perfect track to learn the art of driving. I must visit that track next year.

The Miata is a perfect car to learn with. You will want to keep as much momentum through the turns as possible. In time, when you get more comfortable, you will have to stay off that brake pedal as much as possible. I've heard drivers say the car is driven like an on/off switch. Full throttle or off throttle. They didn't use the word brake much at all.

Day 1, your goal should be to "just get comfortable" with driving at speed, passing, getting passed, using your mirrors, hand signals, etc... There really isn't a need to have R compound tires your first time out. You are going to love it!

Pete, hope to see you in October. I'll give you a shout when I'm registered and ready to go.

Shane, I think SCCA is more widely known than NASA, but I prefer to compete in NASA because their rules structure allows almost any car to be competitive. Most of their classes have a power to weight component used to even the field. SCCA primarily uses a more traditional approach by policing modifications and weight. Too much can sneak through and this creates tremendous confusion. With a simple power to weight ratio, most anything goes as long as you keep within the limits of the ratio. Of course, you can't create a full tube frame car in most classes.

I'm not looking to pump up my resume to go pro racing. I just want to get out and have some fun competing.

Awesome write-up Mike :D I love to read other peoples racing experiences. Glad to hear your really getting to learn your car, I know from personal experience that feeling comfortable just sitting in a car is one of the most important keys to being fast in it.

I'm doing my first track day, a PDX, at Mid-Ohio in early August in my new (to me) '90 Miata. I can't wait, I know it'll blow any autocross out of the water.

Give me a heads up if you're ever heading to Mid-Ohio, I'd love to meet you there.
