Camshaft possibilities?

[Rusgo]

After so many years of being available I imagine people must have better impressions on the potential for the few different cam grinds for these trucks?

Type4, R&D, etc.

Is there any potential for better efficiency and power in the low to mid range with a quick spooling turbo system installed? Or is the factory cam as good as it gets in that range?

Less smoke under load would be awesome too. I notice the higher power rigs push alot of smoke under load.

I know @typ4 Typ4 has a cam.

From what I understand, of the ground cam's available the typ4 cam will be the best for lower rpm power. I'd really like to see the same truck dyno'ed with the different grinds on the same dyno to actually see the differences.

And I have a torque cam ready to ship. Works really well with a quick spooling turbo and it will pull all the way through the RPM range.

Yeah was thinking the same thing. Before and after on a turbo and an NA engine would be awesome with the Typ4.

I'm sure the R&D guy Justin has done it, but he leans more into the higher RPM range of things for peak power. Guessing that cam decreases lower end efficiency.

Correct me if I'm wrong on that.

All else being equal, does the cam increase cylinder fill at the low range over stock?

What are the affect on boost levels and cylinder pressures?

Trying to increase power in situations like pulling up a hill at 1500rpm under good boost without downshifting.

Very interested.

It should since it's a "bigger" than stock cam. I ran for about four miles before I had a valve break the head off. There was too much material taken off of the heads on the 7.3 that I'm running now to try a bigger cam. I wish I had more experience, but I can say that boy did that N/A 6.9 RUN for those four miles!

 

[IDIBRONCO]

It's a Typ4 cam.

I would still think that it would improve the cylinder filling at low enough RPMs that the turbo isn't making much boost. Like below 1500 RPM.

There really aren't many cam grinds for this platform compared to gas engines, and that's kind of a norm for all diesel engines. Reason being is that I think you'll realize more improvement per dollar by going to a better turbo/system or adding an intercooler then you'll realize by swapping camshafts.

I've never tried a cam from russ, or anybody else on any turbo diesel platform. NA is a different story, and gains can be made stock vs custom cams when NA. But turbo diesels don't really seem to be cam sensitive IMO, and I don't think I've ever seen dyno sheets showcasing improvements from any of the cam offerings I've seen.

[IDIoit]

both are great products!
I put a R&D cam in Asmith's truck, and the powerband was great.
I have a Typ4 cam, and it grunts off the bottom end!

it all boils down to your intended use of the vehicle.

when you ask for a comparison, remember rear gear plays a huge part in peoples opinions.

It must because the NA guys that use it, love it.

To late, lol
My other truck with the exact same turbo and load has less bottom end than the 4x4 and even has lower gears, Difference? the cam. It makes a good , noticeable difference.

I have Russ' cam in my 6.9. Certainly help it become a usable haul rig.

Unless you don't plan on using your truck as a truck.... meaning if its just a toy/hot rod......... then for me there is only one choice.... typ4's torque cam.

It simply makes your IDI truck better at being a truck.

My two cents anyway.

With forced induction cylinder filling numbers are a moot point.

Cmon man that’s not true at all, forced induction doesn’t just make head flow irrelevant because the intake is pressurized...
