I took my EF Si race car to the dyno last week and made some decent numbers for the engine still being stock. I ordered a new race-head today though, so I'm hoping for 125-130whp after some tuning.

here's the link in the RR/autox forum where I posted first, but I thought you guys would be interested too.

The baseline run was actually about 115whp, aside from that odd spike that caused it to show 118.



I have a 4-1 stainless steel Kamakazi header for sale too if anyone wants it. Just PM me
