BIG BANG 6.0L LS (GEN 3&4)-SBE-TWIN TURBO-29 PSI! MAX BOOST!

FULL BOOSTED RESULTS (29 PSI!). JUNKYARD SBE 6.0Ls (Gen 3 vs Gen 4). We ran both a gen 3 and gen 4 6.0L to find out how much power the stock Block, Crank, Rods & Pistons can take. Of course we added ring gap, then topped them with good heads, cam and intake. We also added twin s475 Borg turbos and an ATW IC with Ice water. We cranked up the boost til they couldn't take it any more! Help us figure out what happened on the Gen 3 6.0L at Mega Boost!

Richard, this is my most favorite test you've done. Mainly because I'm building a twin 403 stroker. After reviewing many of your videos on the LS 6.0's I have to think the intake and cam played big roles in your torque findings. On the Gen IV it seems you used a intake and cam that was designed for twin turbos. Let me know what your thoughts are. Also, I think both test may have been over turboed for such a small engine. Wouldn't 66-72mm turbos work better? What do these turbos look like when plotted on a map?

[@jaimeozuna5879]

Great video just great! Love all the info👍

[@Erichhh]

Gen 3 rods buckle at a lower cylinder pressure than the beefier Gen 4 rods, and the higher torque production of the Gen 3 at the lower RPM meant that it had higher cylinder pressure vs. the Gen 4. Usually the rods buckle in an "S" shape due to the I-beam cross section being weaker in that direction. This makes the rod shorter, which makes the piston pin bosses hit the crank counterweights. The pin boss gets dented, then grabs the pin. One key difference in Gen 3 was that the pins are press-fit into the rod eye, vs. full-floating on Gen 4. This grabbing/binding makes the piston crack and break, then massive destruction happens from there because there's an unrestrained T-shaped battering ram bouncing around in the cylinder bore.

I have a question I wanna build something that can be daily driven and not have a ton of lag. 4500rpm looks like when boost comes on I'm looking more for 3000rpm range to make it more driver friendly. Is it possible to test it on littler smaller turbos and still make 1200 or more HP for good low grunt then crank the boost and race.

[@zackthomas5707]

New to forced induction, but I love this channel! Awesome video as always. Gonna try and take a stab at solving this so please correct me if I'm wrong, but if you reduce the timing in that rpm/ air mass range and maybe add a tiny bit more fuel to keep things a little cooler during that ramp in period(poor mans power enrichment if I may), that would pretty much do it wouldn't it? Also, if you limit boost on the intake side through the BOV assuming that's possible, you might spool those compressors up a bit faster by bypassing restrictions in the engine, reducing resistance on the compressors and work load on the turbines. Then you could dial it in perfect ramping in exactly how you need it. Like I said, I'm new to forced induction on gassers so by all means school me if I'm off in left field. Again awesome video.

[@laborer4321]

Great work!!! Definitely was the tq that that pushed the gen3 over the edge. What s475 were you using on the gen3? Either run the s475 but with a bigger turbine wheel to slow down some of the boost or run a bigger cam to soften the midrange tq. Also was it me or was there fuel leaking on the gen3 driver side rail? I have a gen3 4.great with a t4 s475 (7575) with a jfr 212/212 that I daily.

Powdered metal rods were used in later model 7.3 powerestrokes. They're not that great at handling torque

[@53chevsled]

I think the powdered metal rods of the gen3’s are weaker rods than the gen 4’s but at the same time the camshaft timing events of the twin turbo cam used in the gen 4 would also make a big difference in the torque curve/delivery , either way a great video showing the limiting factors of both gen’s 😎👍👍

Trying to make the most out of a stock bottom end. My first change would be the fuel Nitromethane would let you run cooler and make more power with less psi. But will not be for a long term deal. Don’t hit it hard off the pull and check the rods for any sharp points where heat can build up. Round them off.

[@slysithejuicegy]

To really push the gen 3 I think you need both strategies. Cam\head's\intake\turbo to shape the torque curve and boost management as a final safeguard. There is no point trying to make power up high if the combo is spent. Anyways this is all old news in the 4 cylinder world. They push boost right to the ragged edge of the rods, piston's and head gaskets. The tuner can window the block on command.

[@nathanlodder1006]

Thanks again Richard!

[@Levibetz]

Interesting stuff! I agree with bleeding the boost in. Get the engine to rev harder, it looks like the torque curve isn't dropping off too hard. If you can make more power between say 5500 and 7500, that's a win for a race car, that's where it'd be during a pass.

[@yuyaarai8207]

I’d like to see the comparison between draw through turbo setup vs the blow through turbo setup. Also I’d be interested to see if draw through setup works just fine with EFI just like pre-turbine water/methanol injection but with gasoline or E85. I appreciate you and your videos.

[@dalethomas9307]

Im my experience pre turbo water/meth injection is hell on the compressor blades. Think about how fast the compressor is spinning and the fact that it is ingesting liquid not a vapor. there is never enough inlet pipe in front of the the turbo to get the nozzle far enough away from the compressor for the liquid to totally atomize.

Definitely has to do with rod thickness Richard. Gen 3s have thinner rods compared to Gen 4s so putting 1330ft/lb will snap the Gen 3 rods all day. After reading some articles I notice that there were some Gen 3s fitted with Gen 4 internals around 2004-05 during the transition to Gen 4. Maybe that's the solution, Gen 4 rods in the Gen 3 block. 🤔

[@2JZLS]

So excited to see what the Gen 4 can do with the 4-bar MAP sensor! I predict over 1750hp.

[@shannonsisk]

I think it might be gear changes that are the hardest on the stock bottom ends. Spinning to 7k making 1k hp and then BAM shift gears and draaaags the motor down in rpm. That’ll make some cylinder pressure

I threw a rod on a 350 in my 260z and had it towed back to my nice gated community apt parking lot not knowing what had happened to it. Later that night a neighbor knocked on my door to tell me my car was hemorrhaging all over the parking lot . The water filled up the pan and pushed all the oil out of the hole in the block I didn't see.

[@escuelaviejafarms]

@@Obshowersyndicate I left all the oil in the engine from the fast lane, all the way to the side of the road to the right of the slow lane. I had to stand with both feet on the brakes to get the 3/4 ton 1972 Chevy to a safe stop. I jumped out and checked out the bottom of the engine, it was pissing oil all over. I eventually got it towed back to base and started working on it at the auto shop. Come to find out the #7 piston popped, literally left a hole the size of my fist in the lifter valley and a chunk of rod went south. I pulled a H.O. 305 out of a burnt up 80's Camaro, dropped it in and never could get it to run right. I didn't have the money to store it at the auto shop and fix it, so I handed them the title to pay for the bill. I miss that truck.

[@RL-RL]

So if possible, always go with Gen4 rods. Got it!

[@alafrosty]

Nope. The Gen-4 rods didn't exceed 1250 ft-lbs. You only know that the Gen-3 rods are known good for 1300+ foot-lbs and that the gen-4 rods are known-good for 1250+ ft-lbs. Without seeing a gen-4 drop a rod on a dyno run, I'd put my money on the gen-3 rods for strength. That said, the gen-4 6.0 rods were designed to be stronger. But how do they really work/fail at the limit?

[@completetuningsolutions]

100% agree with you. Much lower power levels but we snapped a rod on purpose on a 6g72 around 15 years ago, just to find that limit (we broke one off clean, another one bent). Did the same thing, torque dropped faster than the previous pulls and then snapped with massive carnage about 1000rpm later after the decline. What was the pull before like (the one that didn't pop the gen 3 and made it full time, about 1220 ft lbs. Curves more closely mirror lower pulls. Nice work, thank you for the research.

Own a 911 turbo, we have shit rods and they bend with big torque and the trans hates it too. We dork the timing in the midrange to lower torque and run lower boost and then once torque peak has passed we ramp in the ignition and throw boost at it for a top end charge. Still runs great in the mid but as the RPMs climb it takes off - worth it for sure!

[@sydneyACE]

Hey Richard, thanks for the informative videos! Would you mind talking just a little bit about what fuels you are typically using in each video? I'm assuming you're running race gas to prevent detonation, but... Also maybe you could mention timing numbers too? Thanks again!

[@ABetterLifeInc]

I think it was the higher torque at a lower RPM.

[@MastersOfMask]

Can you make a video comparing non VVT and VVT GEN4 on boost. Both with the same amount of boost and rpm and with similar cams profiles.

[@richardholdener1727]

VVT and Non VVT will have different cam profiles by design

[@fastfox23]

I think the biggest difference would be power under the curve, VVT "should" be able to produce more torque earlier and maintain it out the end. That's all in the tuning, manipulating the cam timing to optimize it for that rpm.

[@blk95gsrt]

If the cams were the same and both setups were optimized the peak hp and tq would be the same, but you could have power over a broader range with the vvt.
