Final results [227 bhp / 196 FtLb]

Back on the rollers the other day to check the mapping and ensure everything is ok now the first 1000 miles have been put on the engine.
Consistent results with last time and running fine with no signs of knock. I still however don’t have full confidence with the car yet, and I don’t think I will until the big cams and ITBs are on, so it’s time to speed the next step up 🙂

Can see the vacuum increase on the dyno plot below, so a bigger TB would probably give a little more power. However I think I’ll just jump straight to the ITB’s than mess around anymore on the stock inlet. It’ll be much better overall to take a nice clean cold air supply right from the front. Of course no concerns with cam profile when on ITB’s too 😉
Pretty sure I’ve decided on the ITB set, little peak of them below too!

Mapped again [224bhp / 195FtLb]

More than impressive result on the rollers last week for the new engine! Mapping was by Ray West based near Thruxton: http://www.west-tuning.com/

Still needs bigger cams with VVT delete, ITB’s and an upgraded fuel system. Pretty sure I’ll go for 300deg Catcams and fuel system first (external surge and pump setup), followed by ITB’s after. Would be better from a mapping point of view to do it all in 1 hit, but it’s a lot of cost(!) and the cams need to be swapped asap really to reduce the dynamic CR of the engine (usual problem of small cams and high static CR as it stands now). I could just swap the cams but I don’t think the current fuel system would cope with 230+bhp.
