1984 Lil'French GTI
In order to create a Group B Rallycar, you need to launch a small sports car, like the Peugeot 205 GTI or the Renault 5 Turbo that you have to produce (and sell) at 200 units, no more, no less.
But you have some guidelines to follow. You have to choose between a lesser than 2500cc NA engine or a lesser than 1785cc TC engine. Hard choice isn't it ?
Remember, you are not creating a race motor but a street capable version of it, so power is needed, but MTBF is still quite important or your customers will be really angry.
- No race Headers, No Race exhausts
- 1785 cc max for TC Engines
- 2500 cc max for NA Engines
- Car weight : 890 kg
- MTBF > 40kkm
- Super leaded
2014 Le Mans LMP2
A Small racing team asked you to create a new engine in order to participate at the famous " 24 heures du Mans".
The rules let you 2 options : a 5000 cm² NA engine with 6 or 8 cylinders, or a 3200 cm² 6cyl turbocharged engine. You are not allowed to put 5 valves per cylinder. VVL is also prohibited.
In the full Race event, you are expected to run about 550 laps. Each lap is 13.6 km long. Reliability, Economy and weight are the keys. And remember, it's a small team, they don't have a lot of money
- CNC Allowed
- Race header and Exhausts Allowed
- No VVL
- 4 valves per cylinder max
- Ultimate Unleaded (100)
The Mule : 1988
Making engines for everyday cars is quite easy, but what about an engine for an everyday van, like the Mercedes Sprinter, the Citroën C35 or the Ford Transit ?
Those vans can carry a lot of stuff (about 1900 kg) and they are quite heavy (Around 1400 kg W/O engine). Your typical customer is a company who runs about 50kkm every year with each vehicle. So you need to make a cheap engine, with low services costs, a high MTBF and a low consumption. Oh, it alsos needs A LOT of torque.
- No CNC/ Forge
- No Race Headers / Exhausts
- Regular unleaded (91.0)
- Cast Iron Block and head
