dont want to jack this thread after this ill drop it, Just wanted to make a point and yes you hated it on your bike a 95 but there arent many better "torque cams" just meant for torque alone, Look at my sheet thats posted the 400 did good in a 107.
Don's reply from posting "400-6 cams" page 7 twin cam section
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.
answering Big C's question I think the op would lose going from a tw7 to a tw5 cam, I had a tw7 with +4 gear , it was ok But I personally agree with you this time since he already has a tw7 he needs to move to where he feels a bang for the cambuck spent, a 8, or a 400-6 would a good move maybe even the 408, orrrr tman 626 cam is more friendlier I like that one also, Remembering these arent just drop in cams, work and patience is needed to set them up right as we all know , Tabatha's 110 with a 400 was around 139 trq / 118 hp , The S&S 625g looks good also lots of good choices for both big hp and trq numbers with the heads matched to the cam. There are a couple of 110's around here with the woods 408-44 and they run very,very well low lift, just needs some more compression
