Man take my hat of to you for all these cam tests. Would be great to see these 4 cams tested on a ve 6l or 6.2 req port head car to see how they go on req port head car
Would love to see how a Truck Norris or a Red Hot would go in a NA LS3 manual weekender. Been eyeing these 2 as well as 2 VCM cams and a kelford but my main concern is drivability over performance being manual
I would love to see the BTR Stage 3 V2 - they recently revised it and I suspect it might be the best choice for the most horsepower yet still streetable cam, especially once you add good heads and intake. That said, I did just pickup a Truck Norris for my manual C5 to tide me over while I practice my tuning since I'm still on stock heads and you can use inexpensive LS3 valve springs due to the lower lift compared to the others. Great tests, thanks for sharing!
In the process of dropping a RedHot into my Harrop 2650 equipped LSA engine. Produced 850 hub hp on E85 on the stock cam. Hoping for mid 900s. The sheer volume of testing you put out is phenomenal. Love to see it.
I have a 7.3 Godzilla. It is going in a 1976 F150 Ranger XLT. I went with the BTR Truck Norris. Great vid. I watched your other comparison before i chose my cam.😊
Hi mate id have to look it up but their was a bit of history with the red hot and the name. Its in the recent viral interview with that auto podcast. Im quite sure when they where testing they found this cam performed allmost better then all their other cams on every positive displacement and also N/A. They couldnt change thier other cams of course or remove them so im quite sure it was named red hot like the hot sauce becuase you can put it on anything! Answer to your question: customers who want future proofing or go centrifugal or PDS blower down the track this is the cam will perform just as good as a PDS stage 3/4. I cant wait for thier canted valve heads! They are stating the perfom allmost on PAR with a CID head at far less cost. When i do the build you might see me in your shop! Kai
Love these videos. Richard holdener has done American comparisons but on an engine dyno. As I've said before im going to come to you when i need my l77 worked on.
Great video! I've had to jump right on UA-cam when i get upload notifications for these videos, I've found them so fascinating. That Truck Norris cam has a tonne of low range grunt! Very impressive, but exactly as you pointed out, it wouldn't be for everyone with its manors. It's what would hold me back. I still hope you may do a small cam heads / manifold vs big cam heads / manifold test. I know so many shops indicate as you have that if you're doing heads and manifold you should use a bigger cam, and thus this what the internet says too. But i got fantastic results with heads on a small cam 5.7. I wonder if that would be the case in your tests.
You hit on something very big by mentioning the Cam Dr. Here in the US 'we' (Eric Weingartner) had a 23 'cam shootout' when 'Cam Doctoring' the cams some weren't even close to what they were advertised as. I see on each of BTR 's cam cards that there is an asterisk , denoting possible slight deviations from advertised #'s. Would be cool to see any variations from the 'advertised' specs to actual specs. Great insight as to how you'd chose a cam for the application, Thank You for all you do !
@foghornleghorn8536 I'm sure that's there strictly for liability purposes. Not sure what you mean by you can't test an asterisk. You don't need to? You get a cam, with a cam card. And you can check the CAM.
@foghornleghorn8536 Yeah I don't know why BTR doesn't put the actual exhaust duration on the cam card. If a competitor really wants it, they can just measure the cam. Also, the sales guys will tell you the cam overlap, so all you have to do is plug in what you know to a cam calculator like what's on Summit's website and you can find out what it is. For example the Red Hot cam has 8.5 degree's of overlap. Which means with what we know, then it has to have 248 duration on the exhaust. If I were to speculate, I bet they do it because the public might ignorantly make judgments about a cam based on duration when there's so much more to it than that.
GREAT TESTING..... SOMETHING STRANGE I JUST SAW.. ON BTR WEBSITE, THE LS1/LS2 STAGE 2 V2 SAYS 221/24X .624"-.636" 112 LSA.... THE ONE YOU GOT IS 221/23X - I WOULD THINK THE CAM CARD IS CORRECT, MAYBE WRONG ON WEBSITE...🧐
@@IndependentMotorsports They more than likely changed the spec as per the Cam Card, Cam card is Correct... website is old spec... I suppose your talking to BTR often, you can tell them its wrong... Can i ask have you done a Cam Change and worked on a Callaway C4B engine.. i have a 2003 VY SERIES 2 GTS COUPE. Manual...mine has done a Lifter, i will be doing more headwork, more comp, cam , LS7 lifters, rod bolts, timing chain, oil pump ,rings , bearings etc...I was going to talk to you about a Cam, you stock Cam Motion, i like the Little Chopper but i reckon it need a little more lsa for my use... or maybe the LOW BOOST FILMS cam.. i will call you, is that ok ???
I have found that finding someone that knows how to tune is the major issue, I have a very respectable 6.0 built and in my truck with a Norris NSR cam and the 300K 6.0 I took out will out run it. It runs fine, sounds good it just wont perform.
@@IndependentMotorsportsthanks for the reply. This is the dumbest question I’m sorry. Can you smooth it out to some degree at idle within the tune? I actually own the truck Norris cam. However, I’m yet to install it as I’m slightly nervous.
We can smooth it out quite a fair bit, But that will defeat the purpose I would probably recommend going with a different camshaft if that's the case @@johnflanders1952
All good if you want a imported product but do the right thing and support Au manufacturing. theres just as good aussie ground cams. This post is for the viewers not the creator.
Did you not see all the other videos that I've done with Australian products, I don't need to defend myself when it comes to supporting Australian jobs and employment I would like to think I'm a decent contributor with the amount of money I throw around to Australian companies.
@@IndependentMotorsportsMy comments not meant for you its meant for the people viewing the video as you say you just do what the customer wants and pays you for and yes ive watcthed all your videos for about 2 years
Truly fascinating, cannot thank you enough for the time and effort you've put in to these episodes! funny that for such a low to mid RPM torque and power focus, the TN has such a low LSA and even relatively small lobes for LS territory .. FYI i did my own spreadsheet by eye based on your data between it and the VCM532, basically i see the TN making an average of 5% more torque and power from 2400 to 5000.. after that, particularly kw, the 532 matches and barely goes above, barely a few kw between them until 6600.. with the 532 presumably being less cranky on the 112 LSA, but is a higher lift cam (more valve train stress???) .. i guess like you say, it just depends what you want!!
Man take my hat of to you for all these cam tests. Would be great to see these 4 cams tested on a ve 6l or 6.2 req port head car to see how they go on req port head car
We will be doing that when we put the 6l in
Truck Norris is the king. 107lsa👌 we are talking street engines here!
Brian tooley re wrote the cam book. 107 lobe sep was crazy in an ls1 called abit old school but still is the best for tq.
The Eric W cam test has proven that. David vizard didn't come first but he designed the cam to be used not just win. Lots of below the peak power.
@@Low760vizard was 14th. Btr had 10th and 17th with 2 different cams. Nk performance won in all categories coming out #1

Once again proved the tighter LCA at 107, makes the most torque. Richard Holdener always found the tighter the LCA the better the torque.
Legend, thanks!
Another Awesome Video 👍🇦🇺
Bloody amazing video mate 👌🏾👌🏾👌🏾 love ya work
Hey mate sorry off subject but can you do a video about catch cans, closed and breather types? Supercharged L77
The red hot and stage2v2 vs the SUM-8715-2
Hi...could you try a Howard's cam . .224/230 on a 110Lsa...Please...😊

I'd bet the BTR lobes are some of the most accurate on the market. They check every cam with an Adcole 911.
@foghornleghorn8536 Huh?

Hanging out for the next video when you do heads and intake
Ive got a LS3 v2 stage 2 being put in ny car right now ❤
BTR3 Best NA Gen4 Cam..
Is there a cam the same as the truck Norris but with more lift
Anyone else notice that the stage 2 v2 vs redhot less exhaust duration on a 112 makes more hp and torque probably idles better as well

Have you don’t the crow cams 1212 yet ??
It was featured on the previous video of camshafts

What are you doing with the Stato when you’re finished with it?👌
I don't think we will ever be finished with it 😂
You can see see the stage 2v2 makes more low down torque than the Red Hot and would be better suited to N/A
Btr stage 4?
When you comment about the truck norris cam does it buck and carry on whilst driving at low rpm? Or is it just grumpy at idle?
It's a very choppy cam at idle so it tends to transfer through the car
@@IndependentMotorsportsthanks for the reply. This is the dumbest question I’m sorry. Can you smooth it out to some degree at idle within the tune? I actually own the truck Norris cam. However, I’m yet to install it as I’m slightly nervous.

@@IndependentMotorsportsthanks for the advice. Gives me something to ponder on what I should do.
Put it in John. I absolutely love mine in my ls1. A good tuner sorts it out no worries. Mine drives perfectly with standard stall but sounds amazing.
