The Porsche engine was supposed to be well down on power to the Honda or even Ford or Ferrari, and the 87 car was basically an interim from Steve Nichols between the 84-86 car and the lowline car of 1988.

If they did have new parts, who knows also where they went for Monza, because the Macs were again much slower than the Hondas IIRC.

So maybe the reason for Prost's race pace - despite the World Champion's comments - was the new engine?
During the Hockenheim test the World Champion had lost two engines. Depressing, after the problems at Monaco, Ricard and Silverstone, but there was some cause for optimism: Porsche believed they found - and solved - the reliability problems with the TAG V6. "I cannot say what thay have done" Alain said "but they have made a . . . mechanical change which will not help us on power, but should make the engines last much better. I feel much happier about everything than at Silverstone" The first of the revised engines, for Prost's use, arrived on Friday night, and the following afternoon two more were delivered for use in the race.

Heavier pistons with more robust gudgeon pins added to the TAG turbo's reciprocating mass, but Porsche rebalanced the crankshafts prior to the German GP at Hockenheim where Prost flew until an alternator belt snapped.

"McLaren - Small duct for gearbox radiator. Bosch and Porcshe carried out considerable development work on the TAG engine in the interests of reliability and improved fuel economy, even if it meant a slight reduction in power. Problems believed to have been caused by earlier modifications which caused engine vibrations"
