least they have run a 9 now.
Watching the runs though, there is too much engine for the chassis setup, its all over the shop, bobbing and weaving etc.
If they get that sorted instead of throwing more power at it it will be quick
well...who knows how much more/less air a GT35 is flowing at 10psi compared to the little Hitachi the car came with.
might be running hugely lean at WOT.
if you just cruise around at low load/throttle I cant see there being a problem. give it the berries and expect to be looking though the for sale section for a new RB
700hp worth of turbo
yes, you need a tune.
whether that is simply a nistune board or a motec m880 is up to you
but now you will need bigger injectors etc or you will have a car slower than standard
