They do colt stage 2 cams. Before I get a short from Ashville...I wanna see/hear results of the Straub Tech cam. If its better I will have Ashville use that one instead of the colt cam.

River City Diesel also offers cams in different stages.
Stage 4 has some serious lift....
The RCD stage 4 cam has way more lift than the Colt stage 4 cam.
1000 hp has been done with stock cams before the aftermarket cams were even available.
Here is RCD specs: (notice it says the stock cam was designed to promote EGR flow, and these were for efficiency.)
Stage 1 $649
Drop in replacement with corrected valve timing
increased lift and duration for efficiency VS the OEM grind that was designed to promote EGR Flow
Works with stock valve springs and RCD upgrade 120# springs.
No Piston fly-cutting required. RCD Chromoly Push Rods recommended.
Duration 170IN / 185EX Valve Lift .385"IN / .368"EX
Stage 2 $699
Hotter Street use.
Drop in use, no piston fly-cuts required.
RCD 120# Valve springs recommended for competition use.
RCD Chromoly Push Rods recommended.
Optimized valve timing, increased lift and duration for maximum torque, horsepower and mileage.
Duration 181 IN / 195 EX Valve Lift .412"IN / .400"EX
Stage 3 $749
Hot Street / Competition use.
.060" Piston fly-cuts required.
RCD 120# Valve springs required.
RCD Chromoly Push Rods Required.
Optimized valve timing, substantially increased lift and duration for maximum torque, horsepower.
Duration 187IN / 208EX Valve Lift. 467"IN / .450"EX
Stage 4 $799
Extreme Competition use only.
060" Piston fly-cuts required.
RCD 120# Valve springs required to prevent coil-bind / valve float. 1.850" installed height
RCD Chromoly Push Rods Required.
Blueprinting of cylinder head required to ensure valve installed heights and to prevent coil-bind
Optimized valve timing, substantially increased lift and duration for maximum torque, horsepower in competition vehicles.
Duration 197IN / 218EX Valve Lift .518"IN / .500"EX

Yeah I saw Josh post the new cams a while back on FB. They were using colt cams. I wonder who makes the cams that they're using now.

I would guess maybe Josh. Not sure who took Jared's place when he left!

The specs I posted are the RCD new cam specs.
The thing is...Chris says he can do more with less, but I think all he is doing is taking away the duration from the intake valves opening BTDC.
Say you have a cam that says it has 210* of intake duration...it might:
Start to open the intake valve 15* before top dead center.
Stays open for the intake stroke, 180*
Is closed at 15* after bottom dead center.
15 + 180 + 15= 210* of duration.
If Chris' cam starts to open the intake valves at 0*, or top dead center...and the lift on his cam has say .010" more lift...his is doing more with less.
I also think that is why he is only making one cam for this, and one for that. (Ported/unported)
The rpm range will only be in the stock rpm range...up to 34-3800rpm.
If you wanted more rpm...then you need a different camshaft.
My stall is 2400....do I want to only rev to 4000 rpm??? Nope.
I want a wider power band then 1600 rpm.
It's like he is choosing to pick the low hanging fruit, by making a couple of camshafts that will be more efficient at low rpm, but lose top end power.
But...90% of diesel truck owners use their trucks for hauling...not racing, or high performance.
I could be way out in left field...so don't take any of this too serious...I'm just trying to get as much information about different cams as possible.
Maybe Chris will jump in, and clear it up for everyone...including me.

We're left to speculate because he says big things but doesn't have the data.. As soon as he puts the data out there all the speculation will end and we can make an educated decision.

Just seen it on fb.
Side action diesel did 766/1492 with Chris' cam.
Not sure what the engine combination was...I'm bettin 6.4L
And from what I said earlier, it looks to be true...wicked bottom end, but falls off on top...dyno stops around 3100rpm.

But how much HP was gained from the cam upgrade?

That's just it...there is no information at all...just a graph.
What did it do stock?
Or are they just going by factory power numbers, and comparing to this?
I don't know...
Looked again, and the dyno starts wobbling just over 3000rpm.
Why post chit on a forum or social media with no damn information?
Kinda like saying: "Had a big surprise today!"
And it was on Straub technologies fb page...not side action. (But it was their truck)

I am not a sales... and I am not biased... but I wanted to share a little more info on the straub cams
If anyone is curious... just call up Chris and he will answer any questions that you have. He spent about 30min on the phone with me answering any and all questions that I had.
Extended power you are 100% correct... his main customer is set to be the 90% of guys who are just looking for a good cam for a "stockish" truck. Probably a 500-600hp truck that will not be revving higher than 4000rpms. BUT>>> he said he can and will make a custom cam for anyone that wants one. He will custom grind to your specific needs.
Don't quote me... but I believe the graph was from a 6.4 running 100% nozzles, twin pumps, and 63/75 turbos, stock heads/bottom end. I think it gained around 140tq and 60hp with just a cam swap. The graph was cut short because the rail pressure started to surge.
Although Chris might not have "all the data"... but he has provided WAY more than any other company out there. It amazes me that there are ZERO before/after dynos for colt cams which have been out for MANY MANY years.

I will start a post in a few days . I have not had time to do so. Let me ask you guys this ... Everyone is hung up on the 4k plus rpm range crap. I would like to see more grafs on this post with a 59/76 combo as well as a 63/75and see where the truck makes peak power at....
It's like the earlier days in the gas world all the guys want to watch the tach spin faster but there is no power up there.! So unless you guys really hate your valve train "as there is enough broken rocker arms as it is " ....or really want to watch the tach go round and round I don't see where a truck that only makes power at 3k-4k rpm is even usable and remotly desirable .....

I don't need the high rpms. Mine is a daily...hell it doesn't really even see much over 3k rpms 95% of the time.

Short of 200, but 60 is very respectable
what a mess
New member
agreed but what did that truck make for power before the cam swap ? isn't that a hefty build for a good power 6.4? what are the lower hp trucks goin to gain from these? like 550 trucks just wondering ? those are nice gains tho agreed

....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.

Only real comparison I have with my own truck is back when it had an Edge tuner with attitude, 4" turbo back exhaust and an AFE stage one intake.
Stock cam, stock injectors, stock turbo.
It Dynoed 416rwhp.
So if it doesn't matter what size of turbos are on the engine...me switching to the Colt stage 2 cam gave me an increase of over 360 hp over the stock cam.
Should post the Straub cam results in the 6.4L threads, not the 6.0L threads...it's misleading.
