No KR?

I recently dropped pulley size from a 3.5 to 3.3. I have a plog, factory dp, u-bend replaced with straight pipe, 1.9 rockers, zzp stage 1 tb, factory plugs, factory thermostat. WOT= 17* of timing, 10 pounds of boost, less then 1* of KR on 91 octane. I usually run 94 but was about to run out so had to settle for 91. I expect to have 0 KR with the 94. This is good? :th_scratchhead:
 


yeah thats pretty good. Those 1.9 rockers seemed to help quite a bit. There has been talk on Riviera forums that 1.9's dropped 5-6* of KR, you have all the supporting mods, even then im surprised your running that small of a pulley. Do you have any kind of tune?

Yup...those things bloooooooooooooooooow LOL

Good deal man and for sure a factory freak...can't imagine that on my car LOL

Also would like to wonder what your car would do with a 180*, Headers, Ported Blower, and colder plugs/PRJ's. Just my thought ;)
