  • HOW WELL DOES THE TRUCK NORRIS CAM WORK WITH BOOST? IS THE TRUCK NORRIS CAM BETTER THAN THE SLOPPY STAGE 2? DOES THE SLOPPY STAGE 2 CAM MAKE GOOD LOW SPEED TORQUE? CAN I RUN A TRUCK NORRIS CAM WITH A TURBO? IS EVERY CAM A TURBO CAM? DOES LOW-SPEED TORQUE IMPROVE TURBO RESPONSE? CHECK OUT THIS VIDEO WHERE I COMPARED THE TRUCK NORRIS CAM FROM BRIAN TOOLEY RACING TO THE SLOPPY STAGE 2. THE CAMS WERE COMPARED BOTH NA AND WITH A SINGLE S475 (T6) TURBO FROM SUMMIT RACING. THE GOAL WAS TO MEASURE THE POWER DIFFERENCES AND CHANGE IN BOOST RESPONSE OFFERED BY THE TWO DIFFERENT CAM PROFILES.

    Rebuilding my gen 4 5.3l block rite now, had to go with the ss2 bc of price point, replacing everything so spent the cash on parts that aren't as easily done later. Gen 3 706 heads,pac 1218s, gen 4 intake with flex fuel injectors, all new bearings and rings. Engine has flat tops in it factory so hoping for a reliable lil ripper. The ss2 I put in my 6l (decked 243s, and gen 4 intake) was very impressive, hope to have the same with the 5.3, just can't beat the power gain from the ss2 , especially since it's half the price of about every other cam out there

    Love that shirt, hahaha! That's great! Excellent to see this. You answered my question about this on the last live chat - the reason I was asking was because I had read a 20+ year old article that was saying overlap was terrible for boost, and with the Truck Norris at 107 LSA, that had me worried. But like you said, and exactly like this here video showed, boost just does what the cam does N/A, only with bigger numbers. Awesome!! Thanks Richard! 👍🍻

      @@SmittySmithsonite you had the concept correct, but It doesn’t bleed of boost or any of the other commonly repeated inaccurate “facts.”
      How does it affect performance?
      Combined with Duration, the LSA determines Valve Overlap. This overlap has a significant impact on Engine Vacuum and idle quality.
      Camshafts with a "tight" LSA (106° - 109°) will usually have more overlap.
      Camshafts with a "wide" LSA (110° - 118°) will have less overlap.
      That’s from an article about cam lobe separation angle on Sunmit racing’s website.

    • @TravisFabel
      @TravisFabel Před 2 lety +1

      @@Mattvardaman A lot of these rules of thumb of what you want for lobe separation while kind of ignoring the actual duration stem from older engines when they had flat tappets. Because the cam ramp angles were not as steep, the "rules" were a lot easier to go by as you would always have overlap with tighter lobe separation angles because you could only ramp down one valve and ramp up the other valve so fast.
      So fast forward 50 years away from that old technology to what we have today and we are snapping the valves open and closed so much faster that you can have a tighter lobe separation angle with more duration on the valve and still have less overlap.
      We live in good times.

      @@TravisFabel I swapped so many hydraulic flat tappet cams in gen 1 sbc engines that I lost count. I’ve had a few modern LS engines, and I’ve done a small handful of cam swaps on truck motors. The power from my current truck’s 5.3 with a stage one pro ls truck cam, long tube headers, support mods, and the tune dialed in with the wideband is outstanding! I’m looking forward to feeling the power of a turbo on the 5.3 in the next year.
      I will say that the cam technology is vastly improved along with cylinder head design/flow. With a modern roller cam My 5.3 with a small duration camshaft 205/217 @ .050” .500/.500 lift 112+2 lsa has more “idle lope” than my 355 sbc with a 224/234 .456/.488 lift 112lsa flat tappet cam. The 5.3 makes more power too. The modern performance age is awesome! I support anyone trying to make some horsepower.

    Richard, I’ve been following most of your LS videos for years and love them! Excellent work. Maybe I missed it but have you ever changed the cam timing. In theory could the timing in the sloppy cam be slightly adjusted to more closely match the truck norris and produce more low end torque? I assume more expensive parts are needed to do this so not much experimentation has been done on you channel or I’ve just missed it. Maybe an idea for a future test.

    @AdamOpheim Před 2 lety +3

    Issue with boost response on my turbo LS setups has always been traction. You have to limit the speed at which the power comes on. You must regulate the power at this point progressively with timing and/or boost control to get a tire to plant on a street. And I'm talking about a drag radial or slick. With a standard radial tire having instant response it useless. Having boost at 3k or below is useless as well. Much more practical to have a larger turbo and cam that brings in the power later.

    • @boost1728

      For performance cars, absolutely. But for truck engines that happen to still be in trucks that tow things, a Norris cam and small turbo like an S366 will do a much better job around town and through mountains. A successful LS build plan depends heavily on application and purpose.

    A 107 to 112 LSA ... a 212 to 228 duration ? IMO as far as NA goes this is not an apples to apples comparison ... but still a great test ...Richard did a video on LSA comparison a lil while back 108/112/120 LSA the 116 didn’t come in ... and if I remember correctly Richard was puzzled when the 108 LSA cam made the most low and midrange torque and I think the most hp but I am old so my memory might not be as good as it used to be ... so go watch it for yourself please ... I would like to see the correct LSA.test revisited with a stock 5.3 and then a 6.0 ... I like the TN cam and I think the specs are more for what any LS truck needs in NA form ... more low end torque... that 107ish LSA increases cylinder pressure (dynamic compression) and helps increase torque ... yes it has a grumpy idle because of that LSA but it works ...Richard I’ve heard you say many times who drives at WOT at 2K-3K rpm .. you press the pedal it downshifts and is above 3k almost instantly and out of that extra torque range .. or you have a 3600 rpm stall and flashes to 4K rpm and you’re out of the rpm range again ... I’m not saying the SS2 is better but I am saying “PICK THE RIGHT CAM FOR YOUR APPLICATION “ ... a 5500lb truck won’t run like you think it should with a 228 and above duration cam with a 112-115 LSA without all the “extras to go with it “... it’ll idle nasty but run like a 🐌 ... now be careful everyone some cam “companies” /retailers will only try to sell you what they have in stock even if they know the DURATION /LSA doesn’t match your combo or maybe they don’t know it doesn’t match IDK but I see a lot of over cammed pickups thru the shop ... but it sounds nasty at idle... now if a nasty idle is all you want then go for it by all means ... someone tell me how sweet it is to outrun your race buddy with the same truck he has and he knows you have a smaller cam ... Great work Richard .. I appreciate the fact that you have blown so many “old wives tales” from the hot rod world out of the water ... btw I’ll buy one of the cams for the LSA test if you revisit it again .. thanks

    So if we take that 26 lb ft Tq difference and look at what it does at the tire, it is a huge gain. So say you are running a 3000 stall converter with a turbo 400 and a 4.11 rear gear. The difference at the tire would be a gain of 661 ib ft. You have to remember you can multiply the TQ but the only way you can multiply the HP is with more RPM.

      The same can be said for the higher torque of the ss2 up top? You are trying to use gear ratios to show a difference when those would be the same no matter what. The reason hp is higher is because tq is higher at the same rpm. That’s how hp is calculated by torque and rpm…

Maybe you mean low end torque is more valuable than top end torque? But that’s only the case if gearing is long and the converter stalls low. The amount of time spent at the low rpm is negligible in a race car where you should never be under 4-5k rpm anyway.

So most of these engines will never see over 6000 rpm. If you study the usable power band of any engine it is very hard to make power over a 3000 rpm spreed. So a street engine making peak Tq at 5000 rpm will not have any power down low to move the car. That is why I am saying you work on TQ not HP. Try to make your peak TQ at 3000 rpm, then multiply that w gear ratio. That will accelerate the mass.

      I've used it on hilly roads, with almost 2k lbs in the bed and it does the job, like a good work truck (3.73/4l80e swap w/stock converter).

    • @Broadpaw_Fox
      @Broadpaw_Fox Před 2 lety +2

      Yes. 😎
      But seriously, the biggest difference displacement makes is that more of it means more power, within the limits of the supporting parts (intake, injectors, head flow, etc). That said, with all the support pieces the same, more displacement shifts the power curve downward in the Rev range. A 6.0l will make it's torque a few hundred rpm earlier than a 5.3l.
      Do remember that horsepower is based on rpm - so the later the torque peak the higher the horsepower. But if it's too late the engine feels underpowered as you wait for that torque - the old feeling of "coming into the cam".
      Torque down low for street/daily drivers, top end for weekend/strip cars. 😉
