Any good info on cams?

[strokin6L]

then why get a cam like this,its a grocery getter then lol (just giving you a hard time)

Because his cams are based up to 4k rpms. What I'm saying is that I don't need one that makes power over 4k rpms. Why would I have a short block built and not upgrade the cam. We all know the stock cam profile absolutely sucks!

From an email from Eric at Inn ovative Diesel:


The rev limiter for the FICM kicks in around 4400rpm. I haven't seen anyone successfully run more, as the truck loses power.

 

[Towerguy]

Is the rev limiter unable to be turned off or raised through FICM tuning?

 

[Extended Power]

Is the rev limiter unable to be turned off or raised through FICM tuning?

They must be able to do it somehow...Eric, Josh, and Tadd, all have trucks/customers with engines running to 5000 rpm.

..I don't have a 6.4L...so this graph means nothing.
....my compounds aren't 63/75 either, but it was said earlier that it doesn't matter what size of turbos are used.
....I'm pretty sure that having a cam drop off on power after 3000 rpm is not going to help make power with bigger compound builds, and more fuel.

Here is a graph of my compounds this fall...high pressure oil line blew off, and killed the engine...but you can see that it was clearly making more power past 3000 rpm. Colt Cams stage 2.


__________________

I never said this cam will not make more power up top. We are raising in IAT so the turbos that are on my particular test truck are out of efficiency at this rpm. Which is fine. These comp 1 turbos are made for the guys who still use their trucks not just making power as u can tell by or tq curve and how broad our hp and tq curve is. This is "useable power"

Now if you want more power up top then fine we would go with a bigger turbine and exhaust housing to free up some top end and keep turbo in its efficiency MAP for the rpm range. In my opinion It will drive poorly and not be efficient also shortening the window on when it can handle taking on extra fuel to make more power.... I look at TQ as efficient nothing else. No matter what engine I am building be a cummins, duramax, or powerstroke, the tq # tells me how efficient I am able to bring on the power. If to compressor map is to high truck has a low "inefficient" short tq curve like the graph you have shown. but a high hp# which is great if that is what you want for hp but the low tq# is its efficiency I mean we all do this for power but on our graph you can see the truck never falls off on power it is sustained suspended so to speak. where one wants its truck to make power is sometimes just not feasible at this time either do to mechanical limitations or in our case... flow limitations. The flow of the turbos are the end of its road for where it is at. We will be leaving this cam in and changing turbos from this point on. But for this cam it works very very well with this setup.

Thanks for the feedback so far Brenton!

Thanks for the feedback so far Brenton!

Not a problem! Just sorry if this all comes out as frustration on the forum but I have a great deal of time in all the 6.4 stuff and I get it that it isn't a 6.0 we also have a lot of time in them as well !! The engines share the same port design as well as small changes to intake manifold and we also have found interesting things on intake manifold testing as well. But that is a new chapter to the book ....but if you guys are not happy with the cam then idk what to tell you because I am very particular as well as not easy to please. So lets get these cams rolling guys ! Like I say you will not be disappointed !

I don't make sell or deal with junk. Everything from our dual fuelers to hardware on our egr kits is quality. If its not how I like it then I don't release it until its done how I am happy with it. I don't want quick sales I want a lasting relationship with my customers that want the best quality products !

I'll be looking at getting a cam in a few months. That's why I've been looking for info on Chris' cam ever since he posted in here and on FB...cause I've been following on FB also with your results.

Emailed Geoff again.
His cams in the stage 3 & 4 are not going to be ready till sometime in March now.

Anyone know who is cutting River City's cams now?

Is Chris Straub offering deals on his introductory cams?

There is a huge difference in price for something that is made from the same material...exchange rate is another thing that's killing fellow Canadians right now...30%
So for a set of lifts and a cam it's what? $1500.00US?
...almost $2000.00 Canadian....Booo!

 

[strokin6L]

I'm very curious about who's doing RCD's cams. I know they were selling colt cams. But when Josh posted the new cam stages and specs a while back on FB...I wondered if maybe RCD found a better cam. I do notice that the RCD stage 2 cam is cheaper than the colt stage 2. Not sure how different the specs are from each other tho.

 

[Extended Power]

Here are the specs on the Colt Cams:

It sounds like pretty much any aftermarket cam using a billet core, is aware of the poor cam profile grind of the stock 6.0 & 6.4L cams.

Here....lets put River City Diesel cam specs up here too:

 

[Extended Power]

Anyone have specs on the Straub Tech cams?

 

[Extended Power]

Found information on Elites cams as well:

 

[sideactiondiesel]

We will not be releasing any specs on these cams.

 

[Extended Power]

Did anyone video the dyno run with the Straub cam?

Are you gonna post the graph?

 

[Vader's Fury]

We will not be releasing any specs on these cams.

Can I ask why?

 

[Extended Power]

There is little data because very little ppl want to do the work of changing just a cam. No one now days wants to do their homework. They want everyone else to do the work.

As far as the right up goes on the new cams will be very soon.

....and why is there no information.....here's your answer....even with others who are legitimately interested in buying a new cam, and are wondering what the specs are.

Cost is a huge factor for me...$800 to $900.00 for a cam from Elite, RCD, or Colt Cams, but they are $1100.00 for a Straub Tech cam...with no information.

So we should buy this no information cam, and give feedback for everyone huh?

And yes, I have sent a text to Chris to see if he is interested in a custom cam for my engine.

 

[sideactiondiesel]

Can I ask why?

Sure can, out of how many of you that are asking about these cams how many of you really know how or what it means and what affects what???

So why should we post are hard work that other companies in the market haven't done just to give out specs on what has worked and what hasent. This is the exact reason why we test our products before they get released not just hit the market with something that is said to work. Like ported intake manifolds. Out of how many companies doing them have taken the time to actually figure out what is going on in the intake manifold that prevents the so called flow issues with the manifold,also how many have done before and after of this to prove gains were to be had???? Hell If I recall I have never seen a flow comparison of ported and not ported intake has anyone else ?? Either way this post is about cams not intake manifolds so I will get back to the subject.

It's like asking rcd who grinds their cams ? Does it matter ??? To me no. Because I don't care about the specs I care about what works. If I want to see specs or have a doubt I degree it and do the R&D spending my and my money on tgis matter This process cost my company a lot of money. To do all this work for just a cam change in a running truck not on a engine dyno here mind you so just for the job equates to over 35-40hrs of work to make happen. Not to mention material and paying our guys to do so. Sorry for anyone taking this in the wrong way. But this is a business and my time and money and effort is vested deeply in this project not just copying off colt or elite or rcd or whoever else wants to grind cams to say they have their own cam to sell. The market has gone away with trying their own products and own ideas because its not as profitable... I get it but I don't want my business ran this way. For anyone I have talked with on the phone about this matter or any others understands how I do business future past or present I want it right or to the best I can offer it that's it. And i have forgotten to mention that there will be no need for valve reliefs with this cam which should also save as a added cost to customer and do to the valve timing events should prove to be more efficient and making more power and better driveability Rant over ..
