Here is my most completed project. But if you know car guys or engineers no project is ever finished. Things can always be improved. This car is highly valued and is very underestimated until you sit inside and floor the pedal, as it is very far from stock.
Stock innocent and slow
Blacked out trim and wheels
First modification was a carbon fiber cold air intake
Original heavy-duty catted downpipe

Description
This is a 2021 Audi s4 that was purchased in 2020. Not long after I slowly started to modify it as I saw the capability of this car. It has 605 horsepower and 625 pounds of torque when fed with 93 octane gas. When I switch to E85 gas, it jumps to 774 horsepower and 717 pounds of torque, which would be for track days. Just about everything possible besides internals has been done to this engine, You can see the list of mods on the right. The car is coming up on 75000 miles, so with this much power, it is going to need a rebuild pretty soon. Every nut and bolt on this car has only been touched by me, it was a lot to learn and I made some mistakes but now I know.
