2009, 110", FLHX, CR-595, SE MVA heads, SE 58, Zilla

Customer bought the heads and TB from a nearly new 120ST engine, then we added 110" drop on cylinders, SE HI Comp MVA dome pistons, CR-595's and a Zilla.

 I have been hoping to see more on this cam. What is the compression set at?

Aiming for 10.8. Will see where it landed when I do the CCP test in the morning.

These heads are too lazy out of the box for this CID according to WFO Larry.

100 tq at 2400 isn't too shabby.

118 ft lb's at a cruising 3K rpm is perfect in my book.  Crack the throttle from there and see ya!!

Very nice run. Do you know what the heads CC'd at?
If it ain't broke... Fix it until it is.

.....  and the piston dome volume ?

The off the shelf MVA's come in at 95 / 96 cc.  To get 11.3:1 with a 4.060 bore 120 (and flat tops) it takes 89cc.  That's a big cut (+/- .050) and it would need the same or more from a 4" bore to get a decent compression in the 10.5 to 11.0 range.

Thanks. I didn't measure the chambers, but reverse engineering the calculator with known measurements puts them in the 97cc range.

Dome volume of these pistons, part #22502-07B have been measured at 11cc's by Mr Sachs and a couple other reliable sources.

CCP 199/199 here at roughly 600 ft above sea level, puts it at 10.77:1, which is very close to the target.

Indeed. I just took one last road test before it goes home. It rips!!

Could it be better? Yes. But this is the result of using off the shelf SE parts without any additional modifications, such as a set of purpose built heads.

I just built a 110"  "B" motor using those pistons . Domes are + 11 cc. I modified the pistons, cut .015" from domes that brought them down to 10 cc.

Didn't follow the whole thead I guess. There is about a .033" difference in comp height between a 120 and 110 piston iirc

 :up: Great run Darren.  That's quite a drastic improvement from a stage 1.  Bet it's a blast ride ... Keep up the good work  :baby:

Aiming for 10.8. Will see where it landed when I do the CCP test in the morning.

Maybe so but it appears at 2200 itís at 80. Seems it would lug at the bottom. I wonder if more compression would help.

Without a doubt...but nothing is free and more compression typically means higher fuel octane / quality requirements and sometimes more difficulty tuning. And although the effects may be minimal, higher compression means more wear on engine parts. I sincerely doubt this bike is a pooch down low, we're getting spoiled now by all these sheets Daren's been producing where  they make 100 ft lbs off idle  :wink: :smiled:
