Custom cams, Volunteers needed

[935racer]

Ok so the stage 2 and 3 cams have been finalized, hardcore race cams are still in developement. So I am going to offer the first couple cams of the stage 2 and 3 models for a discounted price. But wait, there is a catch.

To qualify you need:
 
Install the cam proptly after receiving it.

Establish base line egts and boost in relation to rpm before and after cam install.

Post a small right up on your thoughts of the cam on both vwdiesel.net and vwvoretex.com in the specified threads.

I have tested the cams extensively with local tds and have had no issues with piston to valve clearance using stock cam timing. Passenger Performance cannot not guarantee the same reults unless we install it. If your timing is accurate you should have no problems. Cam pricing for the first couple test cams will be approx 200USD Let us know!

hmmm

Looks like you may be getting some more business from me in the future  :roll:   :lol:

Damnit damnit damnit!  I wish I had my TD and had it built.  Ah well.  I plan on using one of your cams after reading about the characteristics they have.  

Thanks for making them!

When yoout tests will be done and approved, I will buy one  :wink:

Sorry I can't find any info on your cams stage 2 and stage 3 doesnt mean anything to me. Do you know off hand of the specs of these Camshafts.

Thanks

Patience, grasshopper. There's a reason why there's "Volunteer" in the topic title.

Rather than ask the vendor to disclose their trade secret right away, I think most of us want to see the actual improvements the cams give. You could look at each cam's raw specs but that does not match up to real-world results.

I've seen good results with Passenger's cam in local cars and am really looking forward to getting one for my car, but many people here would like some vwdiesel.net volunteers to experience it and post an unbiased report online.

Exactly mark, the idea is to get some opinions from the non locals, everybody local loves them and I think everyone else will too I just want to send a couple out and get some feedback before I start spittin a bunch out. Mark and I will do some g tech runs within the next week to try and get some baseline #'s and boost and egts in relation to rpm. Just so you all know this cam is a total bolt on and can be installed in 1-3 hours depending on your skills. I have the specs for the cam but am not willing to disclose them at this time, like mark said they are just #'s right now for everyone, lets just get some WHP results! Thanks for the complements guys, I don't mind spending the money on the r&d for a good cause. Turbo diesel power :twisted:

I always thought that performance cams (in gassers at least) sacrificed slow running stability; which makes me wonder just how much one of these would make a relatively 'lumpy' engine shake severely. :shock:

Whilst you quite rightly don't want to publish the profile/timing characteristics of your design; I can't for the life of me see why you can't publish achieved/alleged improvements in power etc experienced by these numerous 'locals'... perhaps some letters of commendation. :?:
Whats the difference between 'local' testing and 'distant' testing? Unless they're all relatives.
 Performance of a modified TD in  Nebraska will be the same (with the same mod) to my TD in UK...  If you need to collate more results then perhaps you need to run the tests on your own engine (just in case there is an unforseen problem)... I'm sure you're not like Bill Gates who is quite happy to sell a product that doesn't work; but it may do in the future with a 'patch'.... It would be like me selling one of my Quantae as 'working perfectly'... on three wheels  :shock:

Sorry I hadn't realized I hadnt stated my reults in testing in this thread. The cams offer signifgant increase in spool up time and a drop in egts. I havent g teched any so I can't do any good detailed comparisons but mark will be bringin his car by soon and we will get some gtech #'s that we can all talk about. The reason I want other people to try them out is because I don't want anyone thinking that the locals here are biased, no they are not relatives but we are all good friends. This is supposed to be a good thing guys! I just want to do some more testing and get the word out. I would love to hear other peoples opinions, all the cars I have cam'd and modded here I did the work on so I would love to have someone else I don't even know do it themselves and give an honest report on it.

Ha ha
Now that sounds better :wink:

And there was me thinking you were about to 'experiment' on some guinea pigs :shock:

I'd be up for astage 3 or bigger one for my td im building..im putting the pump on tonight..drop me a pm... Piers Harry's pump guy built my injection pump 12mm ..only problem is th dial indicator set up is screwy with it...its been a pain in my arse...ha
but I'm up for a cam
late me know
 thanks

Hey deo how much travel does your dial indicator have? Mine has a 5mm throw and when I do the pump timing I usually pre load it about 2 or 3 mm, A good dial indicator has an adjustable sleee on it so you can get some preload. It would seem strange to me if you had a 5mm throw dial indicator and couldn;t time the pump. I have talked to piers to try and get osme info on your pump but they don't seem to remeber building it. Do you know if they subbed the work out to NW fuel injection by any chance? They are owned by the same company. I was talkign to them trying to get some differnet pump heads to try in marks pump so we could get some more fuel and mentioned your pump but they didn't seem to know anythin about it. Is your head solid lifter or hydro. I forgot to specify these are hydro cams.

[therabbittree]

Well I have been stumbling with this for a while,.. here's the deal.
When the engine is at tdc, and the pump is locked with the pin, lined up with the static notch and mark on the pump bracket.....I have the dial indicator preloaded about 3mm etc.. I turn the engine backwards and nothing shows on the dial indicator. I even put pressure on the dial indicator plunger, and it is bottomed out and not using the preload.... any how, if I keep turning the engine backwards, I can eventually get the dial indicator to climb NOT DROP...so I think that means the pump is built wrong ...it should be at max lift on the plunger with the engine at tdc..it seems to be at a flat spot between bumps on the plunger with the engine at tdc...hence when I turn the engine backwards, I get no moment until  the indicator climbs up the plunger again ..but way back on the reverse engine rotation.  The problem is how can it be assembled wrong?.. The plunger can't be installed out of time as it has a locating pin right?.. The key way is in the stock location and with the pully locked, the key way is facing toward the cyl head..weird
I am trying to figure it out...  I used to have to jump a tooth on the pump gear to time it before, when I used it with my last 1.6TD. That worked "ok" but it never was right ...weird..  I had told Piers and they told me to spill port time it or use my piazzo setup.. That kinda was messed up too.. figure they would have me send it back and fix it for me .... no. I have not taken the pump apart to check it out as it was sealed by them. But, I think thats the only way to fix this problem correctly.
Any ideas..??
Thanks
Deo

...it should be at max lift on the plunger with the engine at tdc.

Not at all, this might be where you are having trouble. The plunger will only be lifted about 1mm of a possible 3mm or so (with a 1.9TD camplate) at TDC. You should adjust the indicator so that it still has some preload at the lowest point in its travel then zero it. Maybe your dial guage is hung up on the adaptor and is not letting the rod extend far enough to touch the plunger?
