Re: Dynoed the "aggressive" H/C setup Nice numbers man and nice peaks too!!! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
You may be right about the 229 cam. Interested to see your results! Nothing like 12:1 compression on 104 unleaded and 32 degrees timing hehehe!!
Cheers,
Chris

Re: Dynoed the "aggressive" H/C setup What kind of gains have you seen from more timing? My setup doesn't really seem to respond to more ignition advance, so I've got it @ 25deg. right now. I think I may be loosing some low-mid range HP with the reduced timing, though. I need to experiment with some more tuning at the track.

Re: Dynoed the "aggressive" H/C setup I didn't see any dyno changes going from 28 to 32 but I have 2 tunes...one at 28 and one at 32 so I'll see if there are any track changes

Though I can say..it sounds like a stock idle at the current 1100 rpm idle speed <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: Dynoed the "aggressive" H/C setup you might actually want to sacrifice a few peak HP for the bump in torque and better idle.
If it is more than a 5RWHP drop at peak after tuning I would be very surprised <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Dynoed the "aggressive" H/C setup Fireball has the XE ramps for the 232 cam, not the XE-R ramps. If the MMS 229 cam outperforms it, could be that it that has faster ramps. I guess he needs to test a 232/232 110 on XE-R ramps next. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: Dynoed the "aggressive" H/C setup I do think the 229 has slightly faster ramps...I think I'll lose 2 degrees of .050 duration (232 to 230) and ~4 degrees of adv duration.
interesting change should be the 112 to 114 LSA difference
May try a TR230/224 111 next <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
