engine performance

look i just wanted to know if theres an optimum engine perfomance peak thing. when i get new engines theyre usaully slower than the ones that are more worn out?
sorry if this annoys anyone.

How do you check that they are slower?

they get better preformance out of the car. better spots then a new engine etc. in fact im doing pretty good in spain right now with a worn out engine.

by that i mean finishing 17-last or around that with a new to 5-17 with older.

what % are you replacing them at?

Don't forget that your competition doesnt drive with 100% engines. Their engine also get older which make comparising more difficult. The entire setup of the car is also different every race so I really do not know how you want to compare this race to race.

@ brady, like 60

@Lachlan i cant say i've checked that much but i know most of [who beat me] in my league refits there whole car every race and i dont. Never notice much/if any difference as long as the parts are still "green"

we dont refit every race more like every 2 races. but i dont see any problem with an engine being worn
