My old 411bhp FRS when it ran around 290-300 it would keep with 330 converted saffs... So at a guess you would need around 330-350... There the same gearing iirc..

 

cheeRs,what like was 411bhp in frs?what turbo etc?
what power is possible from standard turbo?injectors?
what like are these johnfrs hybrid turbo?

You'll get around 310 out of the standard turbo if you are lucky and have a good exhaust and manifold.

 

Should Of said 310-320 . standard turbo is a gt25.. Does similar numbers to a t3 on a cossie.
