Datto’s First Track Day

Saturday we took Datto to Killarney racetrack for it’s very first test session during one of their Track days. We probably could not have chosen a better day to do testing especially if the goal of the testing was to make sure all temperatures stayed within the limits while driving the car hard. The weather reports stated it was 34°, all I know it was 30° that evening at 12 o’clock. It was extremely hot and seeing that one of the things that we wanted to test was our safety equipment.

A two layer race suit, Nomex balaclava, racing shoes, gloves and helmet does create a oven like feeling when sitting still in the car while not moving, once you are moving along and shifting up and down thru the gears, the heat is non existent, check for clothing being comfortable, just need to figure out a way to get out of the suit.

The mechanical side of the car performed perfectly. No vibrations, no strange noises besides the high pitch sound when the cams is activated, just for the record, I hate this sounds the SR20VE motor makes with the activated sound, probably the reason why they did not fit this motor to allot of every day cars, luckily for us we had helmets on a the sound of a decent in helmet intercom distracting us from the sound. We had no issues with water, oil or powers steering fluid ending on the outside of their intended containers. The temperatures stayed with in limits and quite low in my opinion, I could just consider fitting a thermostat with a lower opening temperature rating.

Highest Readings:
Oil Temp: 98°
Engine Coolant Temp: 87°
Intake Air Temp: 37°

Brakes, besides the sound these Wilwood Polymatrix E compound makes, brakes are very strong with the ability to out brake a few cars. The squeal on these things is terrible, before the track day, they only squealed while applying the brakes very softly, like coming to a stop at a robot, but after a few heat cycles on the track they squeal permanently, especially under hard and soft braking but not at moderate braking, as they want to tell you navigator when you aren’t hard on the brakes.

The suspension felt good, I was able to quickly gain confidence in the handling and start pushing into corners, in the high speed corners the car felt great, even when pulling the handbrake thru Malmesbury corner ( a high speed combination of two corners that is driven as one, seeing they follow each other closely), once you feel the back break loose just apply a small amount of counter steer and feed in the power and the slide is easily controlled, needles to say my navigator was caught by surprise as his instruction to me was take the corner I felt the most at ease with, he did not realize that was my favored corner.

The only problem was what we expect to be a bad Lambda sensor which in turn provides the management with bad data resulting in a lean air/fuel mixture while using more than half throttle for longer than 2-3 seconds. The strange part to it is the fact that the injector duty cycle seems normal for the amount of load on the motor.

All in all I’m very satisfied with the overall reliability of the car, it seems that the car could go for hours on a end, the only sad part is the fact that I could nor drive the car full throttle as I would have liked, but the time will come. It is a nice feeling to stop the car in the pits after the last round, get out of the race suit and drive the car home. Now that I’m happy with the reliability, it time to sort the small issues and hit the gravel for some real fun and games.

Car Boat Truck Mechanical & Bodyworks

Car Boat Truck Mechanical & Bodyworks came on board as a bodywork sponsor, they will keep their eye on all bodywork to keep Datto looking neat.

The owner Chris Gillomee did not waste any time in getting his hands onthe car or should I rather say pieces of it. I dropped the flares at Chris and he immediately knew exactly what I had in mind and jumped at the opportunity to mix up a special batch of Matt Black, a few days later the paint was cured and on first site I was very happy, the relationship between matt and a slight sheen was perfect, thanks Chris and the whole team from Car Boat Truck Mechanical & Bodyworks out in Triangle Farm that made this possible.

Please give Chris Gillomee a call if you need any bodywork or mechanical work done on 021 949 3636 or send an email to the address in the picture.
While you’re at the shop ask Chris to show you his pet project Tiger 1.

Ford Escort MKII Adjustable Monotube Gravel Shock

Some goodies arrived from the pommies, but they forgot to add the springs for the front units.

2 x Gaz GMO-368RBT – Ford Escort MKII Adjustable Front Monotube Gravel Shock
2 x Gaz GP6-2069 – Ford Escort MKII Adjustable Rear Monotube Gravel Shock

These are Ford Escort MKII Adjustable Monotube Gravel Shock Un

its, basically the same spec Bilstein units that were run on the legendary MKII of the late 70's and 80's but the shocks is adjustable. A friend and I will use the same setups, viagra pills thus we will need less spares between the two of us, also making playing with imported springs easier on the pocket.
You will also notice these are all steel, ALU does not last to long on a gravel car.

Current spring rates will be 250 lbs/in front and 225 lbs/in rear for the initial setup until I have a

better idea of what I'm doing on the gravel, all springs will be 12″ long with a 2.25″ ID with a helper spring to assist with keeping tension on the main springs in the event of some airtime.

Now the fun starts to build new lower control arms, top mounts, spacers and steering arms.
