meshmesh - nice, didn't realise you were doing this, now i'd have no hope against you
what made you go to ice instead of back to racepace if you don't mind me asking?
i'm looking for turbo replacements .. not for the imediate future, but in the next year or two (or if the turbos go) So i will be following your progess.. i'm after similar to you and Merli - more response/useable power rather than dyno/drag power....
On another note i find my boost coming on (with my stock turbos etc..) at around 3000rpm not 4500-5000... and as you know i'm running a similar setup to your 270rwkw setup (no powerfc tho)...
i'm also not sure about the falloff at 8000rpm i can't notice that too much... maybe we can meet up and get a ride in each others cars to see the differences..?
