Replacement for TW6H cams : V-Twin Forum: Harley Davidson Forums

tetertrux · 10-25-2009, 01:00 PM

Put about 500 miles on my build now and just dont really like the noise of the TW6H cams. What would be a good replacement set of cams to use that perform as good but dont have the valvetrain noise as the Woods do. Mine is a 95", worked heads, 9.9:1 comp, roller rockers, supertrapp supermeg, PC5 retrofit for my 03. Any suggestions appreciated. Thanks

A set of the HQ 575's come to mind. I have a set and replaced them with the 6H's. The 6H would pull a little longer in the top end by the feel of a butt dyno. Down low they felt the same.

Andrews 54 comes to mind.

The andrews 54 is kinda what I was thinking, I just dont know the numbers well enough to make a good comparison.

The TMan Performance TR590 is a very good cam, quiet and excellent upper-low/mid range punch all the way out to red line.

Ozzie is correct...the T-Man .590 is only two to three hq/tq light compaired to the TW6H .590. The T-Man cam also runs much quiter than the TW6H.
The HQ .575 cam is one of the hardest cams to tune and used with a FatCat it can be impossible to dial in across the board.
The 54 is a good cam and it does it's best in a 96'' or 103'' builds, however it's no comparison to the T-Man .590 or TW6H for grunt.
The 37 cam is a great cam for the 95'' build also but again it won't compete with the likes of the TW6H or T-Mans .590

Any pros or cons about the HQ575's that 06roadglide mentioned? I definately want cams that come on low and keep building good through the mid.

Interesting, I ran the HQ 575 with a Fatcat on my 06 Dyna, thought it was a bit lopey on low speed operation but other than that tuned in great. Great cam but have a hard time thinking it would compete with the woods for low end torque with the extra duration.

+2 on the TR590. Have used it in quite a few builds and it does everything it advertises

tetertrux · 10-25-2009, 08:46 PM

Sounds like I should lean towards the t-man 590. Will it work fine with my 9.9:1 comp? Does it need more? One thing I forgot, my 6h's are chain drive, im am for sure switching to gears when im in there again.

aharp · 10-25-2009, 08:48 PM

It likes at least 10.6

Stay away from gear drive unless your crank run out is less than .003, or you will have new noises!!

I really like mine, although they do like 10.5:1 comp. This cam has the flatest torque line my tuner has ever seen on a 4" crank.
