07 600rr mod hp results

For those of you that like hp. Here are results of doing a full race yosh exhaust, BMC race filter, and an .018" head gasket, and Bazzaz fuel controler.

The gasket should raise comp from stock 12.2 up to 12.9:1. Give or take a tenth. I'd have to say the filter is not worth it from other "tests" I've tried but I wasn't about the mess with taking it in and out to find out on this application. The gasket isn't that hard but aparently didn't give much since typical full exhaust are worth 6-7 or maybe even 8. And 8 is all I got.

Stock made 110, little liberal but its the relative change I'm worried about. Well, lap times. She made 118 hp post mods. I'm thinking with more tuning and a little luck it may make 120. Stock a/f was 12.8ish range, it made 115 w/ 13:1 and 115 again with 13.5:1 a:f. The 118 was at 13.1 or 13.2 and letting it cool off a bit. Maybe 13.5 and cooled down would crack that 120 mark. I'll try it at the track and copare lap times back to back between 13.2 and 13.5 or so. It runs alot hotter on the dyno than on the track. Dyno temps stay between 200 and 230F and on the track I think the warmest I saw her get to was 185.
