Judging from the video intro, it has a stock front bumper with a bunch of ducts and cooling holes and a simple lip spoiler with splitter. GTC-200 wing, sitting at about 5" pinch weld height on 8" wheels with a stock shaped hard top. Is that how it ran the 8:07?
What was Ton's average speed? That's an important bit of data.
Here's another turbo NA street car on the ring. Almost no aero and no hard top, 8:05 here http://www.youtube.com/watch?v=8VSkQTjDcF0
Maybe I need to be like FM and ask my customers to send me money so I can take the OGK to Nurgburging ring for a sub 7:00 BtG.
Since I was the driver (Ton) of the red MX5 (Ringmazda) I can share some information how I got to my challenge of the 8 minute target on the Ring.
I got triggered by the attempt of Jethro Bovingdon of EVO-Magazine / GB to lap the complete Ring (= 20,832km) with an 1995 BMW E36 M3 for a budget under GBP15.000 under 8 minutes, which project was started as I recall in 2006.
The popularity of fast Ringlaptimes has significantly been raised by Sport Auto magazine / Germany who have been measuring the laptime of the car in their Supertest since 1997
To clear things about the laptimes. The Ring or Nordschleife is a track of 20,832 km which can be connected to the GP-track.
The combined track is mostly used for longdistance-races while then the pitsboxes of the GP-track can be used.
Sport Auto measures their laptimes on the Ring of 20,832 but leaves out the part where the Ring can be connected to the GP-track (trackpart T13). The distance of this part is then 20,600 km (thus they leave out 232 mtr which is about 6 - 7 seconds compared to the 20,832km)
For this lap the full straight (Döttinger Höhe) is used.
When the track can be used for Touristenfahrt (trackdriving for streetlegal cars, motorcycles, autobus and so on) the straight is not used because there is the place you get on and off the track, after buying your lapticket.
Since you cannot use the straight it is only possible to take your laptime once you get on the track and you go under a Bridge (timingstartingpoint) and come back on the straight and pass under a Gantry (timingendpoint) hence the name BtG = Bridge to Gantry.
Then you don't drive the straight (about 1715 mtr) but do take in your timemeasurement the T13 = 232mtr part.
So the Sport Auto times are measured over 20,6 km and the BtG times over 19,1 km.
To calculate the time of a 20,6 lap one has to add around 22 to 24 seconds on the BtG laptime (depending on the speed which can be reached on the straight)
So a BtG 8.00 is 20,6 / 8.23
The BMW E36 M3 of Bovingdon finally never reached their target. In the end there has been spend around GBP30.000 on the car and their best racedriver reach around 20,6 / 8.10
My challenge was to do a 20,6 / sub8.00 which would be comparable to the Sport Auto Supertest, which means that the car has to be roadlegal (as is European approaved tyres (E-mark), minimal rideheight of 10 cm (4 inch))
Since I was fully aware that this was a tough challenge I decided to split my challenge in two stages. First I would try to beat the BtG 8.00 for a limited carbudget and when that was achieved I would raise the carbudget and attempt for the 20,6 / 8.00
I bought a 1994 MX5 in 2008 and planned to spend around €8000 on the car (including the buyingprice)
In october 2009 I finally reached BtG 8.01 and spend €8500 on the car.
It was a struggle to reach this time due to the traffick delays. According Damir 130 who analised my laplogging my theoretical bestlap was BtG 7.53.
As the blue MX5 of Dale Lomas shows in his video trackexperience and talent helps quit a bit. His car has around 35 HP less than my car and a bit more aerodrag does a BtG 8.05 but when you substract the timeloss due to traffic his best time would have been a BtG 7.57 without traffic.
But since Dale is a driving instructor on the Ring and lives almost next to the Ring he has more then 5000 laps experience in all kinds of fast cars and bike.
My experience is about 350 laps since 1970 in mostly slow cars. Advantage that the Ring is always new to me, never a dull moment.
In 2010 I started with upgrading my MX5 for stage two (20,6 / 8.00) (bit more horsepower, aero (splitter and wing) and AST 3 way adjustable suspension, frontbrakes). That year I only drove one lap on the Ring. In 2011 I did 5 laps to test the suspension and aero and that was when the video was taken. Lack of drivingtime in 2010 and 2011 and some problems with the brakes gave a fastest lap of only BtG 8.05. The one on the video was 2 seconds slower..
Now for the 6.30. of Emilio. I understand that he means BtG 6.30 which is a 20,6 / 6.52, is it possible ???? Well in my believe almost anything is possible but not always easy.
With streetlegal limitations (no Hoosiers) and no budgetlimitations it will be tough, but not imposibble
Can you do it with the OGK on (european) streetlegal tyres ???? I doubt it but it is certainly an interesting challenge.
I think the calculation of Emilio is a bit optimistic, but only eating is proof of the pudding, so bring it on. Cost of transport is not that high that that should be a problem for a company that is so busy with racing
