Web cams vs Engle cams
Thursday, 29-Jun-2000 00:13:12
Which cam is the best as far as quality and durability.It seems as though people are steering away from the engle cams.After talking to Don Bullita at the Classic he told me about the results from a cam run in at the bergs shop.It seems as though the cam started to flake off material on the lobes.Has anyone sent there cams to the Bergs to have it run in or is this a service that they only offer on the cams they sell.Either way its got me looking twice at my engle cam :/

I know someone that has lost a few Engles over at Bergs, both on the dyno and on their break-in machine. I don't think it is Berg's fault. Cam gremlins? When building the engines I had problems with, I followed the instructions supplied. With the Web Cam, I pre-ran in the cam in my own break in fixture before I put it in my motor. Shane, I highly doubt you will have a cam problem with the springs Jeff used in your heads. (Same as mine). Let me know if you want some more info.

I have never had a cam go flat . I use mostly Engles. Most people Ive talked to about any cam going flat usually had un godly amounts of spring pressure. I know I will probably piss some people off by saying this but hey what the heck, The bergs recommend way more spring pressure than most people do. I want to say more but I won`t.
All I can say is that most "flat cam" stories lead back to one place. The place that worries the most about flat cams. If you put your motor together to the best of your ability then have a little faith. Don`t start second guessing yourself. Your parts are fine. Have fun.

Hi Mark H,
First let me state that this post is not supposed to start any mudslinging. I just want to know the whole story. I have seen you make a couple of comments on this board about the Bergs. I have not been on this board enough to know the history here. Would you be willing to email me some of your observations, reservations, concerns about this issue? I just want to know both sides of the story. Thanks, and keep posting. You always have good advice to give.

I have the upmost respect for the bergs.My Question was the quality of engle cams.I was just curious if the Bergs have stumbled on a problem with them or if it was an isolated case.
I have plans on letting them run my engle cam in for me before intallation but after what i heard at the classic I was wondering If I should use a different cam.
Re: Shane ,I don`t know what else to say...

Re: Re: Thanks Mark
Thursday, 29-Jun-2000 14:23:03
I was just curious.No part is bullet proof Im probably just being overly cautious.Denham put dual springs on my heads ( you were right did want to put triples on them)and the seat pressure is conservitave.I should quit sweating the small stuff.
The cam Shane is talking about...
Thursday, 29-Jun-2000 15:00:46
was an Engle K8 and it had 7800 miles on it when I tore the engine down for another problem. I hadn't noticed anything with the cam, but on inspection the tipe of the lobes were starting to go away and the Scat lifters were badly pitted (perhaps causing the cam wear).
The cam had been run in on the Berg fixture. This was not my imagination it was real. I am now running a Web cam 86b. Zero miles at this point so we will just have to wait and see. The 7800 miles was done in about 6 months so I drive it a little more than some. By the way I am running Berg double springs(vw size). At this point I don't knwo what all this means but the Web cam survived the break-in fixture at the Bergs now we just have to see how it lasts over time. I will be dialing the lift at the valve each time I do a valve adjust. I will early on check it at 1k mile intervals. I know that some say it's a hoax, but it happened to me and I believe it. DB
Re: Hey Don
Thursday, 29-Jun-2000 15:12:18
Did anyone give any explaination as to why the cam gave way except for maybe the pitted lifters.I am just trying to cover my butt before I zip this motor up.
Do you think it would be wise for me to have my cam ran in before i install it
Re: Re: Hey Don
Thursday, 29-Jun-2000 16:13:51
Shane, Clyde told me that the cams that gave them the most greif were the K8 and the 110 two of the most popluar grinds. I don't know if it's the cam profile or what. He also said that they made the most noise in the fixture. Andy checks everything when they put a cam in the fixture. They measure each lob for total lift and taper. They have found many that were ground WRONG. They said that the surface of the cam lobe was not parallel with the centerline of the cam which would cause the lifter to ride on the edge of the cam and cause premature failure. They have seem problems with almost all lifters pitting but the Scat seemed the worst. I now have a set of Scat lifters that look very go so go figure. These were run in with my Web 86b. To answer your question, I would use a cam that was run in.
Just remember that it is no gaurantee. My failed cam had been run in. Andy did say that they used to make lifters a little differently than they are today and that might contribute to it. You should probably talk with Clyde or Andy at the Bergs. They really worked with me and it was getting very frustrating for them and me. DB
Re: I don`t doubt U Don...
Thursday, 29-Jun-2000 19:27:24
I`m sure what your saying happened to you exactly as you stated. And there are others who have genuinely had cams go flat. But I don`t think it has to do with the cam itself. as you stated with your own cam problem ,the lifters were pitted. I stopped using scat lifters because of this exact problem. And it isn`t a problem that shows up every so offen. Scat lifters almost always come back out of a motor with pits! I`m sure this has something to do with their commitment to QUALITY?? Anyway i`ve sold and personaly used many many parts over the years and there is plenty of junk out there but ENGLE cams are not part of it. One last thing about Berg cams. I know they sell there own cam designs that are ground by Engle and are different but similar to standard Engle grinds but does Berg sell the Standard Engle grinds at all??
Re: Web cams vs Engle cams
Thursday, 29-Jun-2000 16:07:45
Shane, the pitted lifters comes from too much heat. In outher words , the engine is running too hot. I have a friend that works at one of the best engine builders in the world. We have talked about flat cams over and over again. It is no lie, cams go flat, I have had 3 go bad.
Run about 175lbs seat pressure, 300 lbs at full lift.
Fill the engine 1 quart over full of oil, and hope for the best. Then engles and webs come from the same billet. Good luck!!!
Thursday, 29-Jun-2000 16:22:48
though the billets may start the same (I don't know one way or the other), I know that your chances are around 5-10X better if you have a Web than an Engle. Ever degree them in? You never know what you'll end up with when using an Engle, and I've never seen a Web yet that wasn't nutz on. That tells me something about what they are doing WITH the billets. Measure the taper on the lobe; Engle are all over the place, Web is perfect every time.
I agree with a lot of what Mark said; I think some of the VW spring pressures are WAY out of hand. solving one problem while creating another isn't good engineering in my book (increasing spring pressures). My next engine will have fairly light springs; I'm
going to see what happens. The guys over on the other side of the pond are taking THIS approach (incredibly light components, like those 38g lifters, 6mm stem valves, etc), to combat valve float, instead of HUGE springs.
If you are still nervous, do what I'm doing on my new street engine; go with a Hard Weld. It's another $150 over the regular Web cam prices (around $80), but WILL NOT go flat, provided the clearances check out. I'll take the $150 hit vs. an engine teardown anyday.
Re: I agree.....Web Cams degree in exact every time.....I have seen Engles out 4 DEGREES
Thursday, 29-Jun-2000 21:49:16
I have degreed plenty of both. Never seen a Web off. I did see an FK10 out 4 degrees however.
I'm not saying "Don't use an Engle", I'm saying, check what you buy.
I still think spring pressure and rod side-clearance (tight) has something to do with my own cam failures of the past.
Shane, I think you will be fine.
You could also talk to Roger Crawford at Heads Up about lifters. Darrell and I were surprised by what we learned.
His # is 714-871-1940
I haven't had a problem with it (knock on wood)....
Thursday, 29-Jun-2000 21:36:31
I had a 110 go bad about 10 years ago after around 20K miles; valve lift was down to around .150" on a couple lobes.
I had one customer's Web go flat a couple months ago, and I GAVE him another one (warrantee), complete with lifters.
My street engine: it's a pretty warm grind, so I'm a little worried. I want to do just what you guys are doing, going way lighter on the springs and use Ti valves, and some other light parts in the valvetrain. I'm convinced the route of making everything stronger and heavier is past the point of doing the right thing!

I heard recently that Engle K-8 cams are not surviving break-in. Has anybody else heard such?
I knew the Bergs were having trouble with camshaft break-in a few years ago, but I thought this was all behind us!

Re: Anybody heard? (Don Bulitta) (30-Aug-2000 09:13:57)
Several pages in Bergs price list #86 dicussed the flat cam problem. One thing that was mentioned was possible changes were made to our oils. I just replaced a flat Engle V-26, this cam was purchased almost 20yrs ago but not ran that much. Bad batch of cams from 20yrs ago? I don't think so. It must be caused by something else. Has anyone given any thought to the effects of a straight-cut gearset? I mean if you can hear them outside the car when it's running, it must create some sort of vibration that travels thru the cam, lifters, etc. And we all run deep sumps, right?, and then lower the oil level slightly. All that oil flying around in there it seems hard to believe it's a lack of lubrication. ARE the cams being made different or is it something else? Food for thought... (n/t) (George Wells) (30-Aug-2000 12:06:37)
Straight cut gears should not cause a problem, they've been in use for years, and wouldn't respond much differently than a timing chain set-up on a V8. Modern oils have more film strength and "lubricity", and "break down" more slowly than the oils of 15 or 20 years ago. Excessive valve spring pressure, incorrect heat treatment (lifter and/or camshaft), wrong radius on lifter contact surface, excessive clearance in the lifter bores ("rocking") are the main causes of excessive cam wear.

When I was at the Bergs earlier in the year... (Don Bulitta) (30-Aug-2000 14:42:12)
The lifter problem has to center around the manufacturing process, e.g., materials and heat treating. Fords, Chevs, and Mopars don't seem to be having as many cam/lifter problems as VW's, so maybe they're getting better goods. Has anyone had their lifters cryo'd? The 300 below treatment is supposed to provide an improved surface hardness; by the way, Parkerizing is a surface treatment that won't do much for your cam lobes except make them look neat and keep them from rusting in their original packaging. (n/t) (george brown) (30-Aug-2000 14:54:41)
What is the difference between work hardening and parkerizing? (n/t) (Steve Arndt) (30-Aug-2000 15:22:21)
Parkerizing is actually an etching process that puts micropores into the surface to hold oil. Without it, the lobe would be wiped flat in seconds. (n/t) (Mike Lawless) (30-Aug-2000 22:14:54)
Parkerizing is a corrosion resistant finishing process developed for and used by the military on small arms and various steel items; there is some etching of the metal surface involved in the process. "Work hardening" is due to high levels of friction between the surfaces of two parts, so it's a kind of in-process heat treatment. (n/t) (george brown) (31-Aug-2000 10:26:11)

Haven't heard anything, but I'm a victim of a flat FK 8
Wednesday, 30-Aug-2000 00:47:47
Bought the cam in May from the local VW outlet. They had to order it in so it may have been "fresh". Followed the instructions and even treated it to 1.16:1 rockers for the first 4000 miles. I'm using Bugpack VW size duals with Ti retainers and Scat lightweight lifters, so I didn't murder it like Tom J. did as posted below. The engine never went over 6500, and only above 6000 a handfull of times. 1-3 exh ground down to .15" cam lift. It only lived 5500 miles. Other than saying "Engle FK 8", it also is stamped "8 C". Anyone know if this is a batch code?
Re: Anybody heard?
Wednesday, 30-Aug-2000 09:13:57
Mine lasted 7800 miles and hadn't gone away completely, but was going away. That's after having been broken in at the Bergs. The Scat lifters I had were full of pits. I'm now running a WEB cam. I now have about 4000 miles on it. I'll just have to wait and see how it goes. DB

If you aren`t making that much then your heads are probably way too big. You also have a realy long rod which is usually done to make small heads or intake systems flow better at high RPMS. But since you have such huge heads/valves with this long rod ratio,your losing lots of mid range torque and most likely not reving your motor high enough no matter how high you rev it. In other words your combo is a little off. I would run 5.7 or 5.8 rods and also sell your heads and go with High flowing high velosity heads with 44x 37 or 46x37 valves and set your spring pressure down accordingly. You may well find that your car still runs the same 1/4 mile times or faster and it will drive better and last longer. An Engle fk89 is a tryed and true cam grind, I`m sure it will work fine for you. I would keep your valve lift below .620 though. Good luck, Mark H
