Good point. I'm very confused about all this. They reuse old engines at different race weekends, once they upgrade can they go back and use previous spec PU's? It's such a mess and utterly confusing.adrianjordan wrote:Am I right in thinking that they can't go back and reuse an older spec of pu once they bring an updated one?
the original intent was clearly that the engines be homologated and fixed for the year. Now that's out of the window, it raises all sorts of difficult questions and inconsistencies in the rules. They're going to have to make it up as they go along.

Other teams might use such a 'clarification' to their own advantage. By now, they'll surely know the answer.
I personally believe they'll be allowed to use both old and new specs. Imagine else what hazards could arise. Example: Mercedes introduces in Melbourne a power unit with 20 used tokens, and they plan to introduce in the 6th race a power unit with 5 more tokens, which are updates to the mgu-k. Now, Hulkenberg's mgu-k dies at at the 4th race, forcing him to use a second mgu-k in the 5th race. But at the 6th race Mercedes introduces and homologates the new parts of the mgu-k. If Hulkenberg is not allowed to keep using the older mgu-k, he needs to use a 3th mgu-k. He'll be stuck with 2 mgu-k's for the remaining 14 races. I can't imagine that being the intent and I believe the fia will allow to let Hulkenberg to run the old mgu-k/
Well,technically they are by allowing Manor and Caterham to use 2014 spec cars. "Illegal" noses allowed for just two teams...turbof1 wrote:The sporting rules about the power unit need to be completely re-written.

frankly i don't know how the FIA ensure that the engine is to the homologated spec anyway !
Indeed. Personally, I can't see how the FIA would be able to stop teams doing practically what they like with the engines since the rules are such a mess. Maybe completely opening them up for a season will be the simplest way of making sense of it all and rewriting them for 2016. We're not going to get the constant engine development people are talking about because of the 4 engines per year rule and the lead time for parts etc. Plus, teams are going to be super conservative. They're not going to rush in a prototype engine part without thorough testing and time taken to evaluate because if it blows then that's a quarter of their engine allowance gone in a heartbeat. I think we'll see some engine problems in the first tests as teams push the envelope to see which mods they can get away with, then in the final test they'll go to a more conservative set up to start the season with.turbof1 wrote:The sporting rules about the power unit need to be completely re-written.

The PU is broken down in to sections,There are like 6:
ICE - Internal Combustion Engine
TC - Turbo Charger
MGU-K Motor Generator Unit - Kinetic
MGU-H Motor Generator Unit - Heat
ES - Energy Store
CE - Control Electronics
Each one has a seal. If the seal is broken ....it can't be used, disqualification. They're allowed to use 4 each of the above six for the whole season.

sure , but who tests each component , and where , before sealing it ?
