It's a great cam, really good in a basically stock 88 and really good on a 95 inch, having said that I would choose the 48 simply because you have the springs to handle it in an 06 and the added lift can't hurt.  If I were to stay at 88 inch and not have plans on increasing cubes then I would choose the S&S 509 every time.

If you decide on the Andrews 26 I would get the 26N and do the hydraulic tesnioner conversion.

I ran a set of 26,s in a stock 88", and later bumped it to a 95". The bike ran real good.. strong little cams. Never had it on a dyno, so don't have any numbers, but definately a improvement over stock. I put a set of Kirby's heads on it when bumped to 95" also

An Andrews 26 at 9.75 cr, in a 98", with a head that flows 255 cfm at 28" +/- is a torque ripper in it's class. 110 ft/lbs should be easy.
It can encroach 100 hp, but usually won't crest that number.

Klammer I cleaned out my pm box.  I think im going to go with Andrews 21, found a new set for $245 free shipping. I have new inner cam bearings should I put new in the cam plate. The cams come with just one bearing for in the cam plate. I picked up two studs for positions 1&2 in the cam plate and 12 pt nuts on there way. Had to buy 12 nuts. only thing tool wise that I don't have is the block to support the cam plate to press out cams and bearings.Watched couple vid where they were removing and installing bearings and cams with a hammer. Not me

When you read about the Andrews cams they say you should check clearence. Do I have to be concerened with clearence with a bolt in cam such as the 21 or 26

Did this on my 04 FXD. Went 95" and a set of Kirby's heads and that bike was/is a torque monster. My son-in-law owns it now and loves it.

26's, mill the heads .030", .030" head gasket, 100 ftlbs and 90 HP. Do the heads and you will get closer to 110/100.

I did this on my '05 Ultra and loved the way it ran. It was snappier than my '10 or my '16!

I run the Andrews 26N in both my 01 Ultra and 02 RK, both with cam tensioner conversions. I do mostly touring and like the 26N in that it will continue to pull with two up. I'm not looking for super-duper speeds. The 01 runs about 3250 rpm at 75 mph which I find is nice for cruising. HP and torque top out a bit over 5k rpm according to my dyno sheet so don't go taking on someone at the track.

My '05 Ultra pulled well into triple digit speeds. I don't remember if i ever topped it out, but i remember rolling over 120 MPH, (indicated, probably closer to 117-118), a few times, once I rode through the infamous high speed wobble. Guys told me the 26's fell off early, that wasn't my experience.  One trip I ran from Newel, SD to Eagle Butte, SD and averaged 95 MPH. It would get 50 MPG running 55 MPH on back roads, although it didn't happen very often.

(forgive tha speed calculations. I have has a couple vodka sours! I realize the speedometer is probably off 5%)

Nope, never did the heads. Oops! It was a 95" too. Dyno said 89 HP, 99 ftlbs. I know I had it up to 125 MPH indicated a couple time, still not wound out.

Yes, but the duration is longer and more over lap on the 26. The 88" heads could only handle a bit over .500" lift so there were a bunch of cams in the early years of the TC where the lift stopped around that .500" mark. The '06+ heads can handle around .600 so it opened it up for cams with more lift.

Today if i were doing a 95" with early heads I would have the heads rebuild to handle more lift and look at higher lift cams.

The 88s only had stock compression about about 8.75. The 26 cams like more compression. Pure stock 88 the 21 should preform better. If your pulling heads to go thinner gasket for the 26 cam I can`t imagine anyone going that far and not going 95 with a bump in compression.

so being that it is an 06 shouldn't have to worry about clearence with a 21 or 26 right

I have had a JM20 (very similar to TW21) and a TW26 in my 2002 when it was a 95". All was fine. Both are listed as bolt in cams.

I've done quite a few low $$$ builds on early TCs 88 inchers using just cleaned up 06 heads, .030" cometic gaskets and the 26 cams.  All were fun rides.

I always checked cams for clearance, even bolt ins, a few wraps of electrical tape over the lobes before a quick check in the case.
Title: Re: Your opinion on andrews 26 cams
Post by: clap on March 09, 2019, 08:03:17 PM
FSG please explain the tape check
Title: Re: Your opinion on andrews 26 cams
Post by: FSG on March 09, 2019, 11:38:28 PM
do one cam at a time

measure the cam then wrap the cam lobe width multiple wraps of electrical tape and then measure again to determine how much you've added to the cam lobe 

insert the cam plate and cams into the cam chest and see if the cam rotates freely, if not clearance is required,
put tape on the other cam and repeat.

this is NOT a 06 cam chest, it's an 02 but it indicates where clearance needs to be checked

Got bike done today. Installed Andrews 21 cams , new lifters , adjustable push rods,both inner and outer bearings and a baisley spring and new plunger both primary and secondary shoes. My TC 88 was a dog but does it ever pull now. I am very happy.And while waiting on parts I built an 8 ton press to do my cams and bearings. Thanks for all you guys advice
