Hello,

I have a 2001 electra glide 88 ci that is pretty much stock. Looking to upgrade to the hydraulic tensioners with the se cam plate and high performance oil pump. While in there I want to upgrade the cams.

I have been doing alot of research between the differnt cams, how they would work for my riding style and how they would respond to a 95" kit down the road.

Right now the tw21 was the front runner however I came across the reaper 525 which I like the specs and the operating range on more.

Let me preface by saying I do not want to do anything with the heads right now.

I know that the typical max lift for a early head is .510". So I reached out to fueling and explained the bike I have, how it is stock and asked if it was a mistake that the 525 reaper came were listed as bolt in for the 1999-2006. The response was that they are 100% bolt in for those years.

So my question is this. Does anyone have experience with installing these cams in an early 88 ci?

Thank you,
Dime

I did the Feuling HP+ camchest kit w/525 cams in my 2004 FLHTI TC88. I replaced my true duals with V&H 2 into 1 propipe at the same time because my local speed shop owner said I'd give up about 10% of the performance if I kept the duals. I run a simple K&N breather on it. After those changes the bike dyno'd 90/91. You could feel the increased torque big time.

Very pleased with the change but after a couple thousand miles I started getting pretty bad leak down from the piston rings so I had to do the top end. Bored it for 95" KB pistons and rings, valve job with new springs and light decking of heads and thinner head gasket. New Dyno run 92/100. Totally different bike in terms of performance. Dyno results below so you can see what kind of torque band the 525 cams give you. Top is just the cams, bottom is after top end rebuild. HP comes on a little late but as you can see she pulls pretty strong where I want it on a bagger 3-5k rpm.

I talked to the tech guys at feuling a few times during the process and they give excellent support. In retrospect I wish I'd done the top end when I did the camchest. Like you I was "just replacing the crappy tensioners and thought why not do cams?" but I could've saved the $500 on the second dyno if I'd done it all from the start. I did all the wrenching myself and had the cylinder and head work done at a reputable local machine shop.

Awesome this is exactly the feed back I needed. I am on a really tight budget so it's only the cam plate, pump and cams at the moment. If I don't need to swap out the valve springs right now this is awesome.

Have to stick with the true duals for now as well which I know will hurt things.

But over all I think these cams suit better than the Andrew's tw21's for now and in the future.

If you plan on using Andrews and a big bore I would use the tw26 at least. I used a tw26 in my Fatboy while stock and it ran fine, but the following winter I added a 95" kit, the 26 runs strong low to mid-range but does start to flatten out at hi-way speed, Have thought about the tw37 now.

The plan is only to go to big bore if the top end needs a rebuild ideally. I would perfer to stick with the 88 ci and be satisfied with the cam job in a perfect world.

Everything I have read is the tw37 needs the big bore off the hop. You can get away with a tw26 but it like a little more compression than stock. This is why I was looking at the tw21. Apparently pulls real good in the 88 ci and does good in the 95" as well when considering I am looking for torque not necessarily HP but won't turn it down

The 37 does need the compression bump of the big bore to run best , the 26 will run in both 88 or 95 but the power curve will shift a little to the left in a 95. I ride a fatboy with a fiberglass batwing fairing and glass bags, stock with the 26's I found it rode good even two-up. I run hi-way about 40% of the time, the BB with the 26 will flatten out at about 70mph. but it pulls good on back curvy roads.

I got talking to my mechanic and we are going to stick to .510" lift and under so the reaper cams are out.

510s with a gear drive,high flow air filter,& drag pipes on my 01deuce,for the gear drive kit with the cams I spent 500$ me and a friend did the work! That said the end result is lots more grunt! The cams come on strong after about 3grand and continue on up to about 5 you'll notice a big difference in the excelleration Just saying I'm very happy with my 510s in fact I'm smiling now as I send this! Can't go wrong with them!! Also the sound of those cams are a pleasant +! Some said that you can't really hear them,not true! Music doesn't have to be loud to be enjoyed! Those bumps are music to my ears!! Good luck,be safer!!

I did look at these cams but the fact they don't come on till 3000 rpm is an issue for me. I think my basement rpm range would be 2500 rpm and ideally running to 5500 rpm. The HQ-0034 and the red shift 511 both come in at this rpm range and come in under the .510" lift mark. Actually both advertise rpm ranges of off idel to 6000 rpm.

On a Harley, off idle is considered 2500 rpms.

For what it's worth, I have an 01 Dyna with the 510G cams, S&S G carb, stock heads and jugs. It sucks down low but is decent once you get the RPMs up. I don't have a tach, but it feel like 4 grand before it comes alive.

I've been running the 525 in my carbureted 01 EG.No worries .Max lift for stock springs is .540. No bind.Awesome upgrade. However if you decide to want more ponies,Need headwork on the 88" that's the choke hold on these motors

Thanks for the reply. Since this post I found out she had Andrews 26 cams already. I also ended up pulling the heads and pocket porting them along with a valve job.

Whenever I need to do an overhaul she will get the 525 cams and 95".

That being said with the 2-1 I built for her, the 6000 rpm module and the modified cv40, she pulls hard all over the rpm range

I did the 525 cam's with head work (Big Boyz) and kept it 88 inches. Haven't driven it yet but sounds good with the Thunderheader.

Bean did the heads on my Dad's 2003 heritage. That was also a 95" with 551 cams. Thing rips.

Thanks for the feedback.

Ok got to ride the bike and definitely runs strong and has good lower end torgue..Has a very good pull also ..Nice cam with a decent lope.
