B6 s4 engine upgrades?
Discussion
I have an Audi s4 Avant v8 and can't help thinking that its under powered especially considering its a 4.2 but only putting out a similar power to an e46 m3 which is a highly tuned engine, so wondered if there were any mechanical upgrades I could to that would compliment a remap to improve the measly 15hp that engine tuners claim they can get from just a re-map alone? thanks!!
As you say the M3 engine is a high reving highly tuned engine. The S4 engine isnt. The RS4 engine is.
So if you spend 10k+ fitting light weight pistons crank, gasflowing heads and have some racer cams designed and ground you could raise the power output to almost as much as an RS4. But these parts are not readily available and it would be cheaper to get a quicker car.
As suggested a good exhaust, air filter + a remap may give you 5%+ increase. Possible 10% if you get tubular manifolds and 200cell cats.
