Hey guys
I did not even realise that i had writen 3000rpm in the items description.
I have seen them create 1 bar of boost on the rb20 highflow at 3600rpm with just a power fc, electronic boost controller,cam gears and the usual supporting modifications.
Sorry about the misleading information it has been changed now.
Obviously different cars will react differently depending on modifications.
The ratio of RB20 turbo's sold to Rb25's is a very large difference with around 1 being done to around 40 rb25-VG30 highflows as everyone generally just upgrades to the RB25 turbo and highflow that.
