I'd rev mine higher with a better oil pump and cams if it still made power past 9 k .I hope to be doin cams this winter if funds allow along with the 4 port solenoid for boost control, lower wg springs and who knows I may end up doing an ERL s2k modified pump also and rev it a little higher as I love hearing that K series scream at 9k people say it sounds like a street bike coming by their house lol .
