Elgin Cams, for a 2.0L 4 cylinder Options

[DanT]

anyone built a 2.0L with D-jet using one of these cams?

Like the results?

Hated it?

There are "other" engine builders and parts suppliers.

Let's say *every* member here said, "build me a motor".
If only 4,000 members did, at what, 20-40 motors built per year, why should people be expected to wait 100 years for a motor? (IMG:style_emoticons/default/headbang.gif)


I couldn't control myself...

Most people are using a "stock" cam. Why is using *another* suppliers upgrade cam so bad?

Is the old trekkor beginning to emerge from his 3 week nap already??? I hope not, I was hoping he'd stay asleep a while longer..

The stock FI system is very difficult to manipulate with a camshaft change. This is due to the way the stock FI system works and the aspects that are altered when timing events are altered with an upgraded cam.

I had a very difficult time coming up with the 9550 and ended up finding out that it worked so well only after the cam grinder made a mistake on the grind I ordered that I didn't catch at assembly! I had used the base cam for the 9550 with stock FI for a couple of years with OK results, certainly the best results of any cam I had tried with stock FI. I then had an engine that made really good power, idled better and needed less MPS fiddling around with than ever before, but nothing had changed! I tried my best to figure out what was different and when checking the cam "dial in" I found that the exhaust centerline and duration were both altered from the base cam. I then purposely had one of these cams ground and the 9550 was born- its now my best selling cam out of 46 offerings because so many people want to keep the stock FI and get better power, drivability MPG and cooler running. Its very funny what a mistake can create sometimes!

At any rate I did not intend to utilize this post to flaunt the 9550 or any of my cams, but I screwed up and ended up doing that anyway. My intention with the original post was to let people know that choosing a cam for D jet that is optimum is very difficult and the negative impacts of an improper cam have a steep price to pay with tuning, temperature and also the fact that most cams have a tendency to create lean conditions at peak Tq which can cause failures, hot heads and a lot of tail chasing.

Overcoming the issues created by the stock FI and a performance cam were difficult for me dealing with nothing but these engines and trying my best to get more power from stock FI. I knew that I could sell much more engine goodies if I could figure out the stock FI and make it capable of making better, broader, smoother and cooler power.

If it took me that much effort and time to overcome using trial and error methods I have no idea how anyone could do it that did not work with these engines primarily. The recommendations made to me by cam experts from every grinder of type 4 cams were some of the worst things I tried when trying to work through this... Thats when I realized that cam guys need to be told what to do, not used as consultants... If I were still only listening to cam grinder recommendations we would have never crushed the barriers that we have with this engine that works oddly compared to others and conventional thoughts are huge handicaps for most people trying to manipulate the Type 4.

My methods of communication are far from perfect and they sometimes piss people off, but thats just me and I have no means of changing, not for anyone, not for any purpose. I'd rather starve or work at a convenience store than to be someone that I'm not. The net is not a place that people can easily express who they really are, so I try to be bold, to the point and effective- thats all that matters and it's only superseded by the actual results of my work.

Its not.. As long as that component is effective. Other cams generally are not effective for stock FI- thats the reason the Capn and others refuse tio use anything other than a stock cam with Djet, because their results with others have been less than favorable. They haven't tried the 9550.

I doubt everything sold by anyone that works with any engine other than the Type 4 specifically. Thats because it is odd, hard to understand and not easy to manipulate. 15 years ago I didn't even trust web cam because they sold more than just VW cams! That was several thousand cams ago!
