one of my mates has soarer with a huge t04 with 1.00 a/r housing (same turbo thats on my car) on a top mount manifold, has a full exhaust, fuel reg, fuel pump and runs around 1-1.5 bar
its prob got around 250rwkws (hasnt been dyno'd yet)
his latest mods to it is a supercharger thats located under the inlet plenum and a fmic
the supercharger runs an instant 5psi which he can now line lock it and do snakies up the road puts a grin to my face everytime
