The most HP possible is 1,791 from the Escudo. That's what TIPS & TRICKS said, but it's a lil' off on some of the other cars. I've been able to get 40 more out of cars than what T&T says is possible.
I think the escudo is 1840 after the first oil change. But I do not like that car! Other wise the most I have is in the Esperante that is 1008 after the oil change and the only possible upgrade. But the F cars will blow away these power hungry morphidite cars on any track except the Test Track.
