Hi Mike,
We have taken a step back from the 2.4 as we tested it last year and we found that the power (275bhp)was peaking very low at 7500 and the torque was very high (220 ft/lb)from 3k.
This suggested that there was a restriction in the inlet and exh. train that was holding back the power delivery compared to the required flow for that displacement.
We have lowered the cc to 2280 and this restriction effect has reduced, we have also improved the intake flow by using a specific measured length and style of inlet tube,which we have tested back to back on the dyno against other systems.We have also improved the timing on the cams to optimise the exhaust flow.
We are now getting the power that we knew was possible from all our development work(against much critisism and disblelief), there is still more to come from the K20 Hybrid, and we still havnt used ITBs yet,
We are working hard on the drawing board to bring more later this year and next season.Our work as you know involves much much more than bolting parts together,these BHP figures do require various aspects of engineering that can not be achieved by simply bolting the parts together.
On the subject of torque, our road Demo car is only a 2.0 with a std rebore,but the way we build the engine and set our cams works in unison with our header and intake to produce 209ft/lb. without a modified head. This combination is ideal for fast road use as it pulls strong from low revs.
I hope this explains a little about what we are up to..
Regards,
Paul,
