Looking at getting some more torque out of my 103. Looking at the Stage IV 92500011 kit. Seems like you get a lot at a price of $ 1655.00. They say torque ends up at around 110. I usually do long rides 2-up and 2800-3000 rpm cruising range. Anyone got any better combos out there in that price range? Kit includes:

• Forged 10.5:1 High Compression Pistons and Rings
• Screamin’ Eagle® 58mm Throttle Body
• Screamin’ Eagle CNC Ported Cylinder Heads
• SE-259 Cams
• Perfect-Fit Pushrods
• Top End Gasket Kit
• Heavy Duty Clutch Spring

Thanks

 

At your cruising 2800-3000 RPM you'll never see the benefit of the se-259e cam the alternative is the get it replaced with the se 585 cam

Mild touring headwork
S&S. 583 cams
107" kit with Compression set at 9.8-1
this will give TONS of tq on the bottom (expect 125+)
The kit your looking at is not going to be what your looking for at all.more of a mid-upper RPM build.not the low end your looking for

 

If you're only lookin to get 110 tq then just do the cams with a tw222 or tw555. That'll get ya there without the price tag.....

 

That is a peak number. I have seen those kits on the dyno and if you looked at the dyno sheets for that kit you would understand what the previous posters are saying. You will not be happy with that setup. Kirby's suggestion is the best way to go.

 

Those .583's smack the torque right up there very early.
Just built a 103"er with them.
Not a big hp producer, but big torque.
If looking for a cam-only boost(and a big one!)
An Andrews 48 will be quite surprising.

Interesting topic, and I'm looking also but minus the ported heads. The 585's are very tempting, but I'm trying to grasp the relationship between performance /longevity.

How far can we go without sacrificing reliability? I can't afford to split cases and throw in a lefty bearing to handle additional loads - and what IS the cutoff for that necessity anyway?

I can see 10.5/1 compression ratios, and cams with up to, say, .600" lift in addition to the usual intake/exhaust/tuner upgrades. But beyond these I would say longevity becomes an issue.

Any experts out there, because I'd really like to know...

 

I did all the usual changes V/H power Duel- Rinehart slip ons -Power Vision-Big sucker AC
Chris Revis Rocket 574 cams = 96 hp &110 tq there is more there but i wanted reliability and didn't want mpg to suffer a great deal still pulling 42-45 mpg,and I didn't have to touch the top of the motor,doing a stage 4 I would guess you would need to change exhaust -tuner-AC also.We've got 24k miles on the 14 Ultra Classic since doing the upgrades with no problems and ride 2-up most of the time,Harley love's all the guys doing the stage whatever upgrades

 

And on the flip side of this 120/120 can be had with a 103" as well.
Not new news here, but our Stage III Heads/Wood 9B cams/Thunderheader/55mm HPI was the recipie.
