F1 » Horner: Red Bull, Renault better prepared for 2015


Tcarr925, Here is the correct information which will either UN-confuse you or adds to your confusion. PU’S are homologated in February for the forthcoming season. In theory 95% of the PU can be developed, 5% is permanently frozen. PU’s are divided into 3 categories, ranked 1, 2 and 3, the total ranking for the parts of the PU are 66. A token system for the parts was derived that allows for change, example, changing a piston will cost 2 tokens, while changing ignition will cost 1 token. Manufacturers will be allowed to chose what parts of the PU they wish to change based on these tokens, with the annual number reducing each year. For 2015 there will be 32 tokens available which means that almost half of the components in the PU can be changed, each year the number of tokens will reduce around 9%. To be continued.

F1 » Renault F1 has ‘huge job list’ for 2015


A final note, the FIA rules regarding the turbosupercharger says “the charge air compressor, the exhaust turbine and the MGU-H should all be on a common shaft. And finally, contrary to what many a self appointed media expert wrote the common shaft mentioned in the FIA rules does not allow for the MGU-H to be declutched from either the charge air compressor or the exhaust turbine, their un-expert expressed fair about things going BANG if something goes wrong with the turbosupercharger will be taken care of by the waist gate/pop-up valve and or cutting off supply current to the MGU-H.

The architecture the three different ICE engine manufactures on the grid are using/adapted . Mercedes, have placed their MGU-H in the ICE (engine) “V” open space with the exhaust turbine on the back outside of the block and the charge air compressor on the front outside of the block. This is termed as a split turbosupercharger. FERRARI, have placed (front to rear) their air-to-liquid intercooler, charge air compressor and MGU-H in the engine “V” open space with the exhaust turbine outside the back of the block. This is termed as a split turbosupercharger. Renault, have placed (front to rear) their MGU-H in the engine “V” open space with the charge air compressor and the exhaust turbine both outside the back of the engine block. This is termed as a combined turbosupercharger.

Golde, now for some comments about “the perceived by the media experts” “gearbox thermal” stress and as to why the gearbox of both FERRARI and Renault was moved further back than the Mercedes installation. Thermal stress, all three have the exhaust turbine on the back and outside of the engine block above the gearbox bell housing. All three use a V6 engine and an eight speed gearbox. The FERRARI and Renault power unites are not longer than the Mercedes. The oil tank of the Mercedes was placed in front of the engine while the oil tank of the FERRARI and Renault is placed inside the bell housing. The fact is that the FERRARI and Renault engines are place more forward then the Mercedes while the gearbox of both the FERRARI and Renault sites further back than the Mercedes box.
