110 to 117 upgrade
« on: August 11, 2018, 01:49:26 AM »

Thought I would share some info about my new motor build and the dyno pull.

Original motor build:
CVO 110 with 10.5:1 pistons
MVA HEADS
58mm throttle body
SE High flow injectors
SE585 cams
SE cam plate
SE oil pump
SE lifters
Rinehart tru-duals exhaust

New motor build:
SE 117 with 10.5:1 pistons
MVA HEADS
58mm throttle body
SE High flow injectors
TTS 150 cams
S&S cam plate
S&S Oil pump
S&S Lifters
S&S Rolling rockers
S&S Fly wheel
Rinehart tru-duals exhaust

Thinking about doing the same build on my 110 also

There are good reasons to port the original heads.

That’s correct. The stock cvo 110 head will probably give you better results.
Also the fullsac exhaust will probably perform better than my exhaust.
I already had the MVA heads so I stayed with them.
Could probably get more torque with the stock heads but the trade off gives me nice flow at higher rpms.

I am the guy that started the thread on cam companies not publishing specs anywhere on their cams. I still believe that you can't know if you have good HP numbers, or what to really expect unless you know all of the cam specs and actual head flow. Same deal with throttle bodies, and flow numbers. Don't tell me how great it is, back it up with real published flow numbers, and at what depression the numbers are generated at! Also due to the fact that almost nobody has a cam analyzer, some cam companies advertise what specs their cams are, but they are in fact bigger.  That's why "you have to use only our special springs with our special cams." This practice was very prevalent in the automotive industry during the 1970s and later during the so-called "Cam Wars."
We do not install, sell, or recommend any cams without published numbers. and we do have a cam analyzer.
With all of that said, and no published cam specs that I could find anywhere, I couldn't tell if your HP numbers are good or not.
Having the cam analyzer allows us to see what the cam actually is, and whether the published specs are correct. It keeps everybody honest.  As the data guys say: "Garbage in = Garbage out."   TIMINATOR

P.S. the MVA heads provide a torque and HP gain over the 110 heads. This is because the MVAs have a lesser volume in the intake runner size to keep the intake velocity higher, and they also out flow the 110 heads too. To get the same results with a 110 head you have to fill the intake runners and grind in other places and then install the 2.120" intake valves. Just buy the MVAs, do a small amount of touch up work, and be done with them. That's why the MVAs start with a different casting.   TIMINATOR

Not really sure what that rant was about. Gave the build with measured result.
Nobody is debating cam specs and measured air flows.

Just showing results with parts installed. Doesn’t need to go much deeper than that unless you want to start hypothetically swapping parts and speculating on outcome.

I used the HD stage IV 117 kit unchanged, the SE High Flow SE Air cleaner, V & H True Duals Header and RC 4.5" slip ons, my dyno numbers were max Torque 123.85 @ 3900 rpm Max Power 113.24 @ 5830 rpm.

That result could be improved a lot with a pipe change. True duals does not help any build.

Thinking about doing the same build on my 110 also
A 110 making only 99 HP leaves lots of room for improvement. I've been getting 129/129
out of 110s using the factory's 103 ACR head.

And I would have agreed with the true duals statement up until recently. I got a sheet back from
a shop showing 127/127 with true duals on a 110 conversion with everything else pretty much the
same. So, IDK. True duals may not be as bad as I once thought. I've been wrong many times, add
one more.  :D

PS: Try some TMan 585s in that thing.

Rineharts are stepped and ok. The true duals is more about the shape of the curve not necessarily the peak #s. Your result is consistent from what I have seen with ported 110 heads not mva. If a 117 can't hit 120 it is ailing. I have those in the 140sq area using the 110 heads and he 117 kit.

Still trying to figure out how a 110 head is larger (port volume)than a mva head

C.C. an intake port on both, or read the Screamin' Eagle catalogue, it says it is smaller.
As for the "rant" if nobody knows the cam specs how do they know if the dyno numbers are good? 
My opinion only, and I have my own dyno and lots of pulls. But I can't correlate to anything else without all of the facts. I expected to see someone post cam specs, hasn't happened. Bye now.   TIMINATOR
