This shows the effect of adding on a JRSC running 7.5 lb of boost to a JDM K20a engine. The intake and exhaust were custom built.

Naturally aspirated the engine makes 240 HP to the wheels. This is very good and due to the excellent exhaust and intake made by Joe McCarthy of Prototype Racing.

Had the muffler been removed, or had we revved it to 9000 rpm, we would probably have seen 300 wheel HP.

In January 2003, the boost will be raised by 1 lb, bigger 550 injectors will be installed and a prototype intercooler will be added. We are shooting for 330 wheel HP.

Look at how the power is increasing at 8400 rpm. This dyno does not show the maximum power. If you were to build the engine with better pistons, rods and valve springs to sustain higher revs you would make more power. On the road this would lead to a much higher average power and much better acceleration. Remember that this engine is running 11.5:1 compression on California pump fuel.

We expect similar results from the K20A2 engine at higher levels of boost.

Compared to intercooled turbo K20A engines we have seen to date running less than 10 lbs of boost, the JRSC makes more power at less boost and with no intercooling. The combination of Honda's K20 engine with VTC and VTEC, the JRSC and Hondata tuning make a potent combination with much more power to come.
