anyone running the tw 400-6 cam in there 110, if so how much  diff. is it from tw 5-6

[HD Street Performance]

Here is a TW5-6 you requested. Owner built and tuned stock TB stock headpipes, no cat, and Fullsak recores.

there is a big difference between those cams,  i have used a 400-6  i love it, longand hard  torque pull  but i didnt have the correct piston valve clearance and bent a valve in a set of  s.e. heads,, Just make sure geometry is correct including the correct springs for those cams , bob woods ones of course and i used his lifters and use his adjustment instructions , along with 50 wt oil ,and valve spring clearances and roller rockers  there are really quiet i was suprised!!!!,  i will put them  back in this winter with hillside heads  but mine is in a hillside 107 cylinder not a 110,, and let me sayyyyyyy  it pulled really hard i miss it!!!!.  love those guys up there in N.Y. they really help you

 ........The 5-6 is for beginners ! It works if you do not want to put in a bunch of other accessories as the 400 demands ! Go to woodcarbs.com and see the dyno differences----You'll be shocked !

OK so we know the specs what will the real world difference be between the two assuming the same and proper corrected for cam compression?
My guess would be not more than 3-5hp and TQ. The 400 would be a bypass in my book and if I was having to buy all that gear to make it work and do the extra work needed to the heads I would use a 9B or 408. Those will require a very good tune and pipe to perform well and in the 110 also require a piston change to get the compression where it needs to be without an excessive head cut.

Suggestion --------- Bob Woods is an engineer and very happy to speak with anyone asking those questions--Why not telephone him and get the info. you want from "the horses mouth" ?
He invented the cams you are questioning ! His telephone number is on his web ( the web that I posted for your reference).

[timtoolman]

comon  Don,  with all do respect   it think there would be more difference than that!!!!

[HD Street Performance]

Do you think?
My only frame of reference is a 95" motor and I did try them back to back. In my own bike (pre 6 speed carbed A motor bagger) the 400 made 115hp 112TQ and was on early but the compression was too high for bagger use (10.8/1). That motor was so noisy I was embarrassed to say I was a tech. People would ask what's wrong? Different case altogether and today I could quiet them down some. The 408s in my 07 run reasonably quiet but that took everything to be correct and a lot of expensive gear including custom valves, corrected roller rockers, Wood rocker supports, Smiths pushrods, Thayer 3 stage oil pump, Wood lifters and very careful setup. Start doing the math it adds up quick. Others will sell the cam with headwork (cutting corners) and not do all that is needed and the end result will not work properly, Bobby will tell you the same.

The 110 heads and added stroke make this a very different case. I know of no back to back tests. There are none on Bobbys website either. I do see several with the TW8 or the TW408 either of which I would use and in both cases change the pistons and on the FBW bike a TB upgrade would be needed to reach those numbers and likely injectors too. Now we have the same torque profile with 100 torque coming in in the low 2,000 range hitting max at 2,500 and a solid 120/120 with a flat torque curve.

So anyone want to try the 400 for a test in the 110, TOFTT?
I may be all wrong, I am game to help with the test.

Choose your poison but the TW400 I would skip, not bad by any means just I personally could not justify the cost of the extra gear for the small potential gain.

Do you think just going thought the gears and riding on weekends and trips there will be a difference that you can feel to the tune of all the added parts needed and the +$60 for the Designer Series cam? I know the dyno winner.

i knlw what your telling,  u and talked on phone before about your experience with the 400-6.  people told me the same thing about the tw-7,  im telling you my tw-7 is  very very quiet at idle (20/50 oil) and yes it took work to get it that way.  but  you maybe right  the 110 is very different engine,  when i had the 400-6  in it was pretty quiet. and i could have gotten it quieter if i had wouldve used better heads,  and if you look at bobs reccomendations it doesnt say a 95"  engine  but i imagine they are in many 95's   i know you know more than me to but i  am just saying my experience  with them  And ive heard many very loud tw-8s  that were louder then the 400-6,  but then i used to repair hot rodded nuclear reactors in a previous  career that might explain a lot ooo

TW-400 cam in 110 engine W/50mm TB / 10.5:1 compression = 139tq&118hp
 Dyno will be available as soon as it is downloaded to me from my H.D. dealer--------
    I tried it too !------------

[HD Street Performance]

That is a very healty result and the most torque I have seen yet from a 110. I assume that is SAE (with correction factors revealed) and as I mentioned the pistons and TB were changed and it is not a FBW bike, they are trending less.

WHAAAHHOOOOOOOOOO

Don,
Many tuners out there are seeing issues, with the ability to extract the power from the FBW bikes.
www.joescyclerepair.com does not seem to be one of them.
100/120 is a common number for him(what we've seen) with slip-on mufflers/air cleaner, on an OE 110".
Have seen VERY GOOD power in the 110"s with the 8 cam @ 10.75 cr.

[HD Street Performance]

Yep I like the 8 too.
I still fail to see FBW bikes do much over 5,500 when the same motor in the pre-06 bikes would pull them out to 6,200+ as they should. No change in hardware other than the 5 speed box and a cable TB (two piece). Why is this? Or are you saying Joe gets them to pull higher by tuning properly? I know the hardware can go there whether it is yours or mine. I also know the FBW TB , manifold specifically, is very restrictive and HPInc has addressed that finally.

Hey Scott, was that 100/120 uncorrected and with no conditions?  What were the numbers in SAE / STD?
