All Hydraulic and otherwise tension sprung H-d Products ( as well as their overpriced and JUNK "SCREAMIN EAGLE" UNITS ALONG WITH THIER cam plate and Cam configurations are JUNK !!!! BUY A GEAR DRIVEN S&S CAM SET as well as their Cam plate Unit and superior Oil pump for REAL performance and reliability upgrade .

Andrews 21N in my 01 Springer---- I might could be happier, but I don't know how.

I would disagree. I am running the Andrews 48 in my 05 Fatboy and love it. The bike pulls like a train for only a cam change and tune.

Thanks for that input.........

I have heard of the A48 being an excellent choice for a 103ci and even read a few good reviews of it in a 96ci... this is the first I've heard/read a report of them doing real well in an 88ci.... I guess I always thought of the 88ci being the domain of the A21... Even the A26, while many are happy with it in an 88ci, seems to do better in a 95/96ci, and with a little bump in compression....

Since this is the first report I've read of the 48 doing well in an 88ci, can you elaborate a little...? Is it stock compression & heads? Carb (CV40?) or EFI? Does it pull throughout the rpm band, or just low and taper off... if so, approximate RPMS...?

I'll have to put your info in the old memory bank....

I'm doing an 88ci cam chest upgrade in the near future, run out permitting, I decided on gear drive A21s.... Always willing to learn/explore new options..

I too did HD 203's in my '04 Fatty and didn't think much of them. In hindsight - 20 / 20 - I'd do HD 204's or Andrews 37's. as both work well
with stock valve springs. Power Commander III's are a good inexpensive tuner and lots of maps available. Imo.

2005 was the first year you could use the A48 with the stock valve springs. It was the year when Harley switched to the B-Hive springs. besides the typical stage 1 hi flow air filter and V&H longshots, the bike was stock when I replaced the cam chest stuff at 14k miles. I picked this cam because I really wanted as much low end torque as I could get with only a cam change. I used the Screaming eagle cam chest upgrade along with Screaming eagle pushrods and V-Thunder lifters. I also replaced all the cam bearings. I bought a Dynajet PC3 Usb tuner from Fuelmoto and had them pre-map it

The bike pulls all the way to the rev limiter setting at 5500

I have a friend who just did the A21 cam in his 2003 Heritage and I can pull past him with no issues

The exhaust sound after this cam was installed is awesome

The OP is currently running the S&S 509G cams so replacing with Andrews 21/26 won't make any difference and tensioners are not an issue. The early cam plate is actually a decent piece of hardware. Upgrade the inner cam bearings and replace the outers and upgrade the stock oil pump with a Daytona unit. If the stock rear roller bearing was not replaced with a ball bearing when the gear driven cams were installed, it should be replaced with a ball bearing.

The OP is looking for more mid range so pulling the heads for Stage 1 porting, replacing valve springs for more lift open up cam selection. The Andrews 48 would not be a bad choice for this application but the S&S 583 with the earlier intake close would really wake things up by bring CCP up to 190psi.

OK before anyone comments about how old the post is that I just replied to, I know.

No problem @djl.
Always appreciate your input. Acknowledging the age of the thread, something may have changed by now. IF the OP even still HAS the bike! But he does state in his first post in this thread that he replaced the bearings, but the bike still had the OEM cams. At least in 2018 it did. ???

In reality:
1. He likely sold the bike by now. (already had 60,000 miles in 2018).
2. I think this is a case where the "Related Topics" section strikes again.
3. This info is STILL relevant for those who own TC88s!!

Thanks to all who posted!

Im not trying to hijack this thread, but how would the S&S 583 cam work with a TC 88B that has a S&S 97 inch big bore kit and SE ported heads? I have S&S 510G cams in it now and it has pretty good numbers but…they kick in at higher RPMs and I would rather have the torque and hp kick in at low to mid RPMS. I installed them in 2007 at 38K and now have just under 100K on the bike (2006 FLSTC)
