Heavily tuned for 480 I would imagine, since B5 S4s run like 350bhp with a map(and minor other mods)? :)
Good bit of private test track that!
Not massively.
Pair of K04s (standard is the k03), rs4 manifolds. 3" decat down pipes and full exhaust, 630cc injectors, front mount and some very good mapping, so not a silly amount of work. Thankfully the previous owner to me sunk the £10k odd that lost cost into it. A massively capable car, makes my Gti feel like a 1.4 which is a shame, but it would've lost me my license very easily that car :(
And yes a very good stretch, especially when the local
Supercar dealership customers are about.....
