I'm thinking of getting a roller bearing t38 for the saff. What rpm would it come on boost? My spec is standard head with bd14 inlet, 200 block with valve cutout standard comp pistons, grey injectors. I was looking for near 400bhp. I don't think I'll get much more as the head is standard

Anyone have a rr graph with a t38 running similar spec/power

 

Would a 4x4 inlet make much diffrence at this level of power?

 

Got one on my saph, have sent you pm
