Minardi M198...............
Discussion
Following its first public outing this weekend in Chicago I thought I ought to make a thread really......
1998 Minardi F1, Chassis 01, In 1999 test car livery with some proto 99 aero. It is totally as it was when the Minardi team finished with it in 1999 including all electronics, software, hydraulics, engine, gearbox etc. etc. It's so original if we bolted the 98 aero back on it then it would pass scrutineering for any race in 98
Motor is the original Cosworth JD V10 with all the bits one would expect in place. It's still built as a race engine so is nigh on 17K RPM capable if required.
Original wheel still in use
:
Original Dynamics dampers rebuilt and still used in anger front and rear.
Period Fondmetal mag wheels crack tested and refurbed. On Carbon/Carbons for brakes obviously! Currently doing the work to put it on modern Pirellis so we can see how much quicker they make it!
MM STEP 6 electronics. On the code from the Canadian GP that year.
Hydraulics pack. Throttle, Gear Barrel and clutch are controlled via Moogs with an engine driven hydraulic pump. Operating pressure is circa 200bar.
Being a completely original car in requires a bit of know how and effort to run. Off board heaters, hyds flush packs, jump batteries and fill rigs are the order of the day. It's a very well engineered car though so running it isn't an effort unlike some. Huge credit to the Minardi team for engineering something that is so well put together in the first place, we haven't needed to change a thing on it to run it today, unlike some!
It's an absolute privileged to keep this noisy bit of history in working order and really looking forward to getting it out as many times as possible this year

Thanks for the new thread.
You said you are doing the work to put it on new Pirellis. This implies it is more than a simple wheel and tyre change, so what does it entail?
Same wheels but the Pirelli has a stiffer side wall and greater absolute grip so some changes to the third, ARBs and spring rates will likely be required to get the best from them. This car was developed around the grooved Bridgestone originally so a modern full slick provides a big performance increase.You said you are doing the work to put it on new Pirellis.

When you say modern Pirelli's would that be the modern spec F1 tire or simply a regular Pirelli slick? I assume the Pirelli slicks that are available off the shelf are not anywhere close to the secret sauce they use for an F1 tire. I would be curious to know how different they really are.
2016 season spec. These are still being produced for the team demo cars etc. that run the pre 2017 wheel sizes but are subject to various agreements before it's possible to purchase them.CedricN said:
Great thread, the more technical details the better How do you communicate with the ECU, did they use some kind of in house software or of the shelf?
It's all via the original Marelli Vision software (so 32bit XP only) with the original Minardi layouts/code which in turn communicates via a pair of specific Marelli interfaces (one for engine and one for gearbox) which connect to an external jump battery that then busses comms, power and a few other things (like remote throttle joystick etc.) down a single umbilical to the car.

What's the component lining the two front shocks?
The linkage across the front looks like an arb, but the pivot point looks like it's attached to some sort of damper, is that variable to control amoint of arb stiffness/shock absorbing across the front axle?

The linkage across the front is an ARB, it operates in twist and the various holes within it allow some tuning of stiffness by altering the moment on the centre of the ARB. Attached to that are the pull rods to the rockers with the third in the centre, the third is essentially a bump stop with various possible combinations of rubbers and packers to alter the rate and total allowed ride height reduction under aero.What's the component lining the two front shocks?

A few slow fly bys from Chicago - https://youtu.be/ICNx5lXVo6w
There was a gentlemans agreement on a 100kph limit hence it not being anywhere near lit!

I always love a good PPBB thread.
F1 cars are the most amazing things.
Definitely take it back to original 98 spec and livery if you can.
Bookmarked.
I'm in two minds on this, mainly because that's not how it finished it's time in F1 with the team. How it stands today is how it left Minardi and it had a decent career as test and demo car during that time...... but also that's not how it raced - decisions F1 cars are the most amazing things.

Awesome car and pics, thank you. It was always said how nicely made the Minardi cars were, nice to see it for real.
They were lovely, and very advanced given the teams budget. Minardi ran a torsion bar car in 1999, Jaguar were still on coil springs in 2004. FRICS in 1993, Blown Diffuser in 2001..... it's interesting to see where the guys from Minardi moved to and where that tech cropped up next AussieFozzy said:
I think one of the most underrated abilities of the Heritage F1 team is the electronics stuff. I know most people find it all a bit boring because its essentially wiring and everyone hates wiring but it is really impressive stuff especially from a small independent company.
It's not just electronics, when you think we do our own Hydraulics, Gearboxes, run a full machine shop, design studio, inspection lab and make 90% of the parts we use in house from a team smaller than most F1 teams catering staff we're kind of taking "lean" to a new level

Fantastic. Bookmarked
Do you know who drove it?
It was Shinjis car back in the day. Do you know who drove it?

Hopefully I don't have the same luck with engines that he did - https://www.youtube.com/watch?v=td7uQYq20SQ

I work at a large gas processing plant and we have a 25kw gas turbine compressor some of its combustion systems are controlled by MOOG bits!! They cause us the odd bit of trouble, will make me smile next time I have to play about with it knowing their tech was on F1 cars!
It's been on most of them since the mid 90's Hydraulics are a go to for F1 due to the power density it offers and ease of control Moogs allow (in terms of being directly driven from an ECU via low current/lightweight wiring requirement). The current choice is the EO24 Sub Minature valve which is super tiny and light:
We're running these on the later 2010+ cars which retain original powertrains. I think we're the only people running them as privateers but luckly Moog take pity on us and look after us with regards service and supply more than they really need to - so big thanks to Moog!

Just over 300KPH currently. I'd like to see what it can do around Monza as we were clocking 330KPH+ with the PS04B when I ran that a few years ago. I do have a racing driver but she's a she not a he
I'm quite happy to admit I have no where near the ability to do anything with this car aside from mostly not fall off and make some noise so it's important to me that there is someone on hand who can put a monster lap in with it when required as there is not better proof that the car is proper than this and it just seems rude to not give the car the opportunity to "go fast"

That last picture, the hose coming out of the cooler has a jubilee clip on it, would it have been like that originally?
No, but then that's part of the water heater not the car and the water heater we nicked from a 2013 Marussia so....... for reference you don't generally have exposed rubber heater hose as part of the engine installation and certainly not bits of it that exit the floor at 45 degrees to the motor Edited by poppopbangbang on Friday 19th July 19:29
