I do mention that its courteous to do the wave off but not mandatory. Kind of like waving to the corner workers. Nice to do, not mandatory, but everyone thinks more highly of you if you do it.

See that's the thing about a Miata, bumping the HP is the absolute HARDEST thing to do. It would sicken most people to hear that the super duper pimp IRTB/Megasquirt setup I had was worth 6 hp over the stockish setup.


Yes that is surprising. I would expect a CAI and Catback to give most any car a bump. Oh well...

Dataloggers are coming way down in price. I hope to be able to test the my MaxQData out this coming weekend at VIR. Once I do get it running, I want to shove it into as many cars as possible to see the differences.


Well I haven't looked at the MaxQData but the others I've seen are all about $1K or more. I'd like to see what that thing does. You can add my car to the list of test mules if you want. I really wanted the one that lets you record your video with an overlay from the DL. So on playback you can see speed/rpm/lateral G/brake/etc on the bottom of the screen.

Do you have any in car video's? I am going to full course with BMW next weekend and wanted to get a refresher from a front wheel driver.

Not yet, but I will after this weekend. I'm sure there are plenty around though.

Richard did you get any video?


Ultimatly I decided that my ghetto video setup wasn't going to pass tech and didn't try. But after it was all over with, I actually wish I had tried harder to get a working video setup going prior to the event.

i had an instructor tell me one time that the folks that progressed quickest used video as a training tool. strictly an opinion, but it makes sense.

I spent about an hour or so last night reviewing my TT video from Sunday. It is amazing what you can learn. None of the 5 laps were really that great.

From that video I have two places to really work on this coming weekend. And I am going back to the HTZ's for some of the weekend.

I can see how it can help. I used it a great deal a few years ago during autocrosses. I have this issue where after an autocross run (and apparently after a HPDE session) that I have a hard time remembering details of the run, so when in the pit I review video.

What is the word on data loggers in HPDE? I am not sure I can see a real reason why you shouldn't be able to use one in a HPDE.

On data loggers I don't think we say you can't use them. What we don't want to happen is folks setting their goal to drive X seconds faster in the next session. That hardly ever works (unless you're Michael Schumacher!). I think having access to data after a session is worthwhile because is will show consistency (or lack of it) and re-enforce why that session either felt good or bad.

For me my data acq is now an in car hot lap timer so I can get real time feedback when I make a change to a corner or two to see if it reduced my time or not.

Ron, thanks for the clarification. I can see your point about not trying to focus on X seconds faster over a complete lap. HPDE is not TT. But I was very much focused in the HPDE on how I could be quicker in lots of places and I knew it was going to drop my overall lap time (whatever it ended up being). And I can see how it would be hard to enforce as you would pretty much have to remove video cams as well and maybe even tell friends in the pit to put away the stopwatch as all of those can be a way to "measure" performance. ;)

Some clubs do, in fact, ban timing equipment of any kind (some include video since its often time stamped). These are usually national organizations who's national policy may have very specific language about it. Since we run the time trial, we really can't have this language, nor do I think it matter as far as our liability insurance is concerned.

What might matter more is your own personal insurance (but believe me when I say thats a topic that is beat like a dead horse on just about every other board I'm on).

Ron said it accurately, we don't want people out there time trialling themselves during the HPDE sessions. Thats what the time trial is for. But used as tool to gauge whether or not a new line or technique made any difference, we don't have a problem with.

That sounds in line with my comment above. Even without timestamp info (which probably is only hour and minute anyhow), you could take a video and time laps after the fact. Even do segment times, etc. if you wanted.

I think I have read that there is a ban on both still photos and video shot at Nurburgring during tourist lapping (non-race or testing). I suspect it was to cut down on the accidents caused by people trying to capture a quick lap on video.

There is a ban that was instituted in 2004 at the Nurburgring :evil: :x Should have had Julie shoot video in 2003. There are several theories most revolving around lawsuits etc.

I mount my camera with an AO Port mount fitted to my rollbar. IT is real stable.

OH boy, the opportunity to one more forum thread about insurance covering track accidents........ :wink:

Wes is right. I look like I'm about to roll my car over compared to Kevin's suspension...

Good data points, Ryan. I wasn't following what Karl was running that closely.

So, comparing myself to Karl, it looks like I have up to 3 seconds in driver aptitude since I was running the Hankooks which are similar to the Azenis, provided Karl was giving it all there was to give on Saturday but consider if he has suspension mods and weather differences between the two days.

So, no votes for just working some more on the driver (data acquisition)? Did you get a chance to use that data acq device over the weekend, Ryan?

It sounds like I could find a little more by improving the nut behind the wheel but not as much as I think. I just keep visualizing the Top Gear episode where Sir Jackie Stewart "educated" James May...and keep telling myself, it's in the driver...it's in the driver...but bolting on some parts for quicker laptimes definitely has its appeal. ;)

--Ashraf


My "aftermarket suspension"

KYB adjustables: F @ 7, R @ 5
Springs: F - 440 lb/in, R - 275 lb/in
Sway Bars: F - 7/8" Adco, R - Stock '93
Tires: 225/50/R15

I ran the above with 14" tires. I found it difficult to have confidence in higher speed curves with the car...and it WAS slower. Going to the 15" tires made a BIG difference in the car's handling and resulting confidence it gave you. One of the best changes I made.

At this past weekend's TestnTune, Karl Shultz thought the car was still rolling a bit more than it should. He suggested a bigger front bar, 100 lb stiffer rear springs and no rear sway.

I agree with the front sway, but won't know about the rear changes unless I try them.

Ashraf, you need to get some GC Coil Overs and stiffer springs. Lower the car to about 12.5 in the front and 12.75 in the rear. It'll make a big difference.

I would think the bigger front bar would increase understeer.

It does but I find the big honkin' front bar necessary. It controls roll VERY effectively.

I have

480F/330R Springs
1.125" front bar
Stock rear bar

I have yet to have instructor not tell me at some point during the weekend that the car feels very neutral. I like to trailbrake :twisted:

A Miata should feel a bit loose. Or it should be quite easy to rotate the back end. At least that's what I recall from driving a stock one years ago. Very controllable.

But then I'm not a Miata expert which is what you really need to find.
