DAILY DRIVEN TURBO LS CAM COMBO! MILD TORQUE CAM + BOOST

FULL TURBO RESULTS! Got a mild (stage, 1, 2 or 3) cam in your high-mileage, daily driver? Can you add boost to that little cam? Check out this test on a 4.8L LS where we combined a mild BTR Torque cam with a little boost, then a little more, then a little more! Torque cams and turbos? It's ALL GOOD!!

[@randystingray6544]

Dr. Richard Holdener at it again, my goodness do you ever sleep?? Your killing it with these videos👍👍.

[@dirtrider2833]

Quite a few of these stories are from years ago. Throwing together a quick over view isn't hard or take long. Stock cam shootout was like 7 years ago. But we all enjoy the videos none the less.

[@SweatyFatGuy]

except traction issues and weak drive line parts.

[@Ribbityibzki]

@@SweatyFatGuy but it does give you the motivation to upgrade!

[@SweatyFatGuy]

@@Ribbityibzki yes it does. Of course I would feel bad needing a turbo to make 600hp. I'm already sorting the traction thing NA

[@SweatyFatGuy]

@@dj4monie My engines break 4 speeds and U joints easily. 500ftlbs from idle to 5500 tends to do that. The only transmissions under $2500 that hold up to them are automatics. My $300 rebuild on a Th400 lasts longer than a $2000 4 speed, like decades vs a handful of passes. Its a different world when you aren't running a low torque weak suck chevy... or a small Ford, mopar, etc. :) I suppose if you had a supercharger you'd have an idea of what driving one of my daily drivers is like. Getting an auto to hook and live is much easier and less expensive than a manual, when you have power. With a tiny engine, yeah the manual is gonna feel faster.

[@bibble05]

My grandma drank Boost and it also worked for her

[@badexamplegarage]

Nobody 15 years ago- "mild torque cam 700HP daily seems about right, just run low boost"

[@Woodstock_Warrior]

Bad Example Garage, for real!!! These dyno videos have blown my mind! I mean, I knew it was possible to make those numbers, I just had no idea how “easily” you could do it!

[@xxxmikeyjock]

how do they call that a torque cam when all it did was increase power over 5000 rpm?

[@Hemihart]

Part number for a Gm 4 bar map sensor (and its cheap) is 12643955

[@ryanm3749]

Richard, another great video. After you've finished the vs the world series, could you put all the dyno sheets on a website for a quick reference guide? This would be one of the best resources ever available to the home builder. The ability to choose (at a glance) the curve you want instead of the peak or general rev range would be amazing. Been following your work for years (still love a rag in the hand, but it's pretty cool to see and hear the tests I have already read-plus all the others!), and look forward to more. Thanks.

[@thehotrodstation3313]

I think Richard ,,,,although every cam is a turbo cam and boost fixes everything. Hehe. The LS is a good start on a turbo combination. You're very humble in not including ,,,, that it takes one Helluva tuner to make these combos "work"...Good job!. Love these vids. Cant get enough.....

[@Dr_Reason]

Really need to get set up to run rpm dependent boost. I love the idea of raising the boost after the torque peak. The way you get more power without needing higher octane.

[@samspezza8328]

The horsepower/boost formula works here for torque as well. At 3600 rpm, N/A it makes around 315 ft/lbs. At 8psi of boost (a little more than 1/2 atmosphere) it makes 497 ft/lbs at the same rpm, which is a little more than a 50% increase.

[@theredwedge9446]

[@almostoemgarage8143]

This video plus the Every Cam is a boost cam are really helpful in proving out was is pretty obvious from a text book analysis of what is actually going on. The best part about these videos is it makes me feel better about my cam choice because the build is NA for now but like any sensible person, boost is in the future! I'm excited what my stage 3 BTR LS1 cam does to y 5.3.and even more excited for what a turbo does to that power curve graph!

This is the best damn video out there for applying power to your application.

[@garywood1285]

Sure would like to see tq & hp graphs in the lower rpm levels along with the boost curves. Nearly everything online starts at 3000-3500 rpms.

[@nocturnalspecialties642]

[@k5rpd]

Back to back Dyno runs with stage 1, stage 2 truck cams vs Stage 1, Stage 2 turbo cams... 4.8 or 5.3 because that's most common... Single turbo then small twins

[@TheBCninja]

I think he has tests with N/A motors and different Cams on his channel. I believe he also did a all cams are turbo cams video. Basically all you gotta do is look at a cam you are interested in, see the shape of the graph they show for that application, and then slide it up based on boost pressure. The shape is unchanged when boost is added... unless the set up is REALLY slow to come on boost :)

[@richardholdener1727]

I've runs lots of turbo specific cams-they work with turbos but we already know that

[@nathanboyles6222]

have you watched @richard holdeners turbo cam video? every cam is a turbo cam

[@BoostedCyclePerformance]

Yes every cam is a boost cam, and will work well overall. But running an actual boost cam vs. these “boost cams” would highlight what a true boost cam does.

[@lwclark]

Love it. Thanks Richard!

[@blow0me]

A cam like that is actually a very good boost cam, and such a cam can also help mitigate the intake, yet up top the intake/turbo will still be able to breathe fine. SO actually quite a good combo

[@exploranator]

For an actual supercharger, more exhaust duration/lift/valve size capability in general usually helps out.

[@alanm7312]

Richard, I really enjoy the way that you run the engines N/A first and then run them again once you have boost. However, are you able to, if known, tell us what the compression ratios are that you are running on the engines and whether the compression ratio when you run them N/A s the same as when you run it on boost. Secondly, when you talk about the power that you made when you run them N/A and when you run them on boost can you please tell us what octane fuel you are running the engines on to obtain those numbers.

[@richardholdener1727]

will do, compression remains the same, boost is usually run on E85 or race-almost never limit it by running pump

[@alanm7312]

@@richardholdener1727 ok, to relate to most people on the street, I personally would run high octane pump. But if you prefer e85 or race (110 octane?) Please run the N/A on the same (you probably are already) to compare "apples with apples" 😊👍 cheers and love your work!

[@coreyphilman3509]

@@alanm7312 Richard, correct me if I am wrong but you do not want to run a higher octane , slower burn rate fuel on a low- mid compression n/a motor it will only lower the power levels? Run the fuel for the cylinder pressure or heat you are creating for accurate power outputs. Alan just learning off your comment, thanks.

[@alanm7312]

@@coreyphilman3509 from videos I have watched, apparently the benefits of running E85 is really limited to forced induction engines. For me, it's a minimum 30min drive to be able to buy E85. So not practical for a street car, combined with the reduced range due to higher fuel to air ratio of E85. If it was just a track car, then fine. But I believe most of the viewers here are collecting info for their primarily street driven cars.

[@frtaylor9]

Okay, now let’s flip it. What if this turbo 4.8 was tested with something with “far too much” overlap. Like a 231/238 111 with 12.5 degrees overlap. Technically that Torque truck cam has -12 degrees overlap and seems optimal for a turbo setup and would do a great job at preventing back-flow, cause in the end everything comes down to valve events as a whole when selecting what one would call a N/A or Boost camshaft.

[@richardholdener1727]

that cam you described would change the shape of the na curve-shifting it up higher in the rev range, which would soften boost response, but the basic shape would be multiplied under boost

[@bdugle1]

Another awesome video! You put so much real info out every time. One question, do you have a compressor map for the S480? I’m curious as to how bad, or good, the size is for the 4.8. I built a little spreadsheet to calculate airflow required to make horsepower and it says 57.1 lbs/min at 1.55 bar and 70.6 lbs/min at 1.92 bar, the low and high boost levels you tested. Are those points way off the high efficiency island in the map? My numbers are an estimate, but they track the power changes from boost very closely, so should be within a few percent. So, did you get a compressor map?

[@richardholdener1727]

I'll se if a map exists. Airflow (in lbs/min) x 10=hp, PR required is a function of na hp
