I managed to pull 225bhp and
280 lb/ft of torque on AMD Essex'x rollers and they are very accurate, lots of LCR's making book figures etc. I think i high flow manifold, im going to get an INA one, great prices at the mo with the weak dollar to the pound! That should free up atleast 5bhp for sure! Starting to think that the forge FMIC may be a restriction for you phil if you go BT, unless you change pipework etc.
Car looks great, like others have said, bhp figures are for willy wavers, mine might not have made the highest RR figures for a ko3s but it drives well and puts a smile on my face when i floor it so that good enough for me!
KO3Hybrid beckons though, for the outlay to performance ratio i think it takes alot of beating!
