@oo10inz I don't think RDRS leaves anything on the table (we can ask @fuelmoto to answer that), but a chart using STD correction factor definitely overstates the performance by about 1-3% vs using the more comparable SAE correction factor.
Well ****. So that would lead me to ask why my numbers are low then. I feel like with the TTS 175 i should be pushing these numbers if not higher using SAE correction.
The numbers APE post seem a little inflated for the CR cams. One shows a 114 putting out 140 HP with injectors and the cam swap only! Also ,the correction factor they use is STD.
Update Sport Glide 114 (11-1 stage 3 circa 2019)
SE Ventilator Extreme AC
SE 64TB/ported intake
Star F35A cam Kibblewhite springs
HPI 6.2 injectors
S&S Superstreet 2-1 decatted plus 3” 2.25 ID pipe in place of Db reducer. The 3” pipe comes out flush with the end cap. +3hp +4tq
135HP @ 6,140
134TQ @ 3,750
Jakelt24. The CR 114 that made SAE 138hp 134tq was legit but they listed the same upgrades as mine only with a crazy custom CMT pipe that had the huge 2” primaries for a big displacement motor or in his case bike used for drag racing.

This cam may be bolt in as far as springs go, but I believe they need more compression. CR told me at least 11.5:1. At 11:1 , they suggested a +4 key to help low end torque.

Well that sucks and advertisement definitely misleading!
I personally want my SE128 to be a torque monster that pulls from VERY start as did my 83 Shovel 80" FLH as well as my 91 EVO FLH.
Don't get me wrong the SE128 does run good and much stronger (no doubt at all) and I am being petty, but when I can just twist the throttle (completely off of the clutch, rolling) on the old 80" bikes and ride out all of 1st gear on back wheel each and every time I ride, I want "THAT"!🤦♂️
Yes, mine will pull the wheel with a quick blip of the throttle but very rarely carries it far.
Yes, it has more to do with the lower 1st gear ratio but still 128" should surley compensate for that loss 🤷♂️😄
(has me seriously considering the Baker 7 speed, which gives lower gear ratio's in the 1st 4 or 5 gears and then just a bit higher in high gear for highway. BEST OF BOTH WORLDS at of course a BIG expense 💰

I really like what you did here with the 11:1 pistons, guessing thinner HG for better quench and the F35A. From what I've seen that's a damn good pipe too. She a hot/max effort stock headed 114 that's making big bore peak hp numbers. How does it feel on the street? I could see that cam kicking some serious *** in an 11.5:1 big bore too.
MattLS6, Spot on. We took .015 off the heads & used a .030 Cometic gasket to tighten quench and bump compression to 11.5-1. Bike runs great. Responsive has never run hot 7,200 miles now since putting in the F35A.
I also changed the belt sprocket and belt wheel pulley to lower final drive ratio from 2.79 to 3.15. Cheap & easy and quiet & smooth compared to a chain conversion. Have not had it to the track yet but it can come out of the hole really Hard. Takes more practice and nerve than I’ve given to it to not spin wheelie or slip the clutch.
Ran a 128 bagger 145hp 155tq on the street 3 runs. Took all three. We only run about 1,000 feet past a marker but I hole shot him good every time and he could not run me down. Lil butt hurt from his buddy’s busting his butt about getting smacked by a lil 114. That was a fun night.
I wanted to do a big bore kit but personally couldn’t do it without doing heads & crank read $$$. I bought the stage 3 107 to 114 kit when the bike was new prior to the days of the big bore kits so I decided to make lemonade. Glade I did its great fun. Occasionally you can still find these kits for peanuts because everybody wants big displacement.
