HOW TO: MAXIMIZE JUNKYARD 6.2L LS PERFORMANCE

[@Taylordrifts]

Another note on longtubes. My ls Miata had a 5.3 with a cam and ran fine with cast iron manifolds and dual 2.5” exhaust. I switched to a 6.2 with a cam. And the car started to run much hotter. I finally did longtubes headers and dual 3” and dropped about 30 degrees in coolant temp across the board. The iron manifolds weren’t much of a restriction on the 5.3 but chocked the 6.2 out like crazy.

[@timothybayliss6680]

@The New NKVD I saw how big the cam was and wondered about that. 5200 gives you lots of tolerance especially if you have a trans brake and a twostage. You can up the launch rpm 50 at a time and see if the tires hold it.

[@rotaryray]

@The New NKVD weekend beatings. a big stall can be done in town but it's really not freeway friendly . Like 4,200 RPMs at 70 mph. Going back to a T56,, less cam , but going turbo

[@rotaryray]

@@timothybayliss6680 what I found is I actually got the most consistency by just flash stalling the car. Sometimes the trans brake just hit the tire too hard. My best 60' was off the transbrake. But for the most part my most consistent times were always on flash stall.

[@brianroagers6894]

So basically stage 2 or 3 cam and all the supporting mods like long tube headers, optimize tune and keep the ls3 intake because it just works great = cheap reliable power! From there it gets very expensive going bigger displacement with higher flowing portend heads topped with a high ram intake. Bigger the air pump bigger the power. Great video as always.

[@wainfiggitty]

@@justinw6448 it's the texas speed vvt 4.2 cam they sell for the l99. I kept the vvt. Their recommended table only retards the timing up to 6°. I had 1-7/8" long tubes, circle D billet triple disc converter (still kept unlocked at wot). It's an AWD '07 Escalade. This combo got me into low 13's at just over 100 in the 1/4. Drivability was fine. Got plenty of attention. Lots of cam chop, people were always looking for the muscle car. Wasn't loud inside until you stomped on it, especially on the freeway with the converter locked. I've since done a full build on the 6l80, added a VS racing s485, 1500cc injectors, hellcat fuel pump, forged guts with 9.3:1 CR. Runs great with the same cam, boost comes in at 3300. Thanks to AWD I can foot brake it and launch at 3400 with full gate pressure (only running 5psi right now). E85 and more boost are next. Lots of fun.

[@kaygaming49]

@@wainfiggitty this reply was a long time ago but maybe you’ll answer haha. I see Texas speed has a cam made for l92 but only in the kit for it. They do show the l99 cams. Are they just as good?

[@wainfiggitty]

@@kaygaming49 I don't have any personal data to compare the two. All I can say is that the l99 cam worked fine for my setup. Probably not great for a tow rig but with a stall converter it responds well as a cruiser. I had my shift points up around 7k rpm.

[@andyharman3022]

Great entertainment on a cold Friday night; Richard discussing my favorite LS engine, the LS3. It's just awesome that GM made race-quality intake manifold and cylinder heads on a regular production engine. Then just add a cam that has 20 more degrees duration, and you can add 60 hp. And that's without sacrificing any torque below 3500 rpm. I've wanted to do an LS3 build for my 4th-Gen Camaro for years. LS3 stroked to 400 cubic inches with an L8T crank, 224 cam, and GMPP ported heads, long tube headers, and stock LS3 intake. Would be easily above 550 hp.

[@rustysausage69]

Why stop at a 224 cam? 700hp is doable with a stout 400inch LS, especially with ported heads. The 235/25 .660/.665 lift cam in my 6.0 (above other parts, 11:1 comp and ported LS3 heads) gets my 6.0 to 600hp

[@andyharman3022]

@@rustysausage69 Above 224 effective seems to be where torque below 4000 rpm starts to suffer, as shown in some of Richard's tests. I'm a road course driver, and have to drive the car out of slow 2nd gear turns sometimes, where the engine is down around 3500 rpm. I'd be happy with an engine that has a broad power band from 4000 to 6500 rpm. I drove the LS1 for years using 3500 to 5500 as the power band. Going from 350 to 550 hp would be a big step up for me. Then I would have to spend more money on a set of bigger brakes.

[@michaelking1869]

I do usually disagree on the cylinder head issue. Anytime I can gain power through the entire curve or in the area’s that matter I’m in. If my choice to gain another 15-20 is more camshaft and less driveability or cylinder head upgrade I’ll take the cylinder head upgrade all day. As long as the head you chose doesn’t kill all low rpm torque from an inefficient design go for it. Get the most power you can the most efficient way you can. Not every change needs to gain you 50hp and more. If I was at 480 and wanted 500 I wouldn’t do more cam if heads would get me what I wanted. On the same hand always buy the head that will work great when you upgrade cubic inches as you should always do. Great video btw. Thank you for your work Richard. This is much better than watching politics.

Stock heads are trash (thin castings useless for porting, big chamber low compression), off-the-shelf cam choices don't even go over 230@.050 from any company, you're limited to Raylar engineering (boat guys) for good cylinder head/intake manifolds, and stock crank is good for only 6-700hp per Raylar advice.

if a simple video with listed parts is too much to dissect, then maybe it might be better to have someone else do the build

What manufacturer was the 224cam, what manufacturer and size wrertge springs. My first LS3 2012 Camaro SS, 6 Speed long tube headers, Borla high flow exhaust. I'm on a budget but want just a little bit more power. Any info would be great. Thank you for your time. GOD Speed

Since the 6.2s dont really need heads and intake, seems like the go-to first mod should be a stroker package.? Valve reliefs will open up more cam options if you want something big.

No lol a cam swap as he said lol A stroker kit is crazy expensive compared to a cam swap, and you can a pretty aggressive cam with how great these heads and intake flow, combined with the displacement.

Hi richard! I follow you from italy with my c6 ls3, here we don't have so much aftermaket variety and many shops in usa didin't sell in italy.. also the price are very expensive with shipping and taxes.. so i would like to upgrade my engine whit a good cam and a long tube, i wanna improve my hp but also i want the best reliability for my engine (here in sicily i think there are 10-15 vette in total), so can you suggest me the best mode hp/reliability? The type of cam.. thank you very much for your free info, you're the best! Happy new year ❤

I love those guys in Cali-we used it a lot back in the day

[@rustysausage69]

5 ways to ID: -most useful is cylinder head castings on bottom pass. side valve-cover rail of cylinder head (google 3 numbers and results will tell you what motors that head came on from the factory). -iron/aluminum block (iron always painted black, aluminum are bare), -casting info on driver side-front of block (will say "4.8/5.3", "6.0" or "6.2" accessory drive covers this up), -intake manifold (not very important, but truck ones ugly, car ones nice), -bore-scope (dish vs. flat-top pistons, useful for differentiating 4.8 from 5.3, or LQ4 from LQ9, L92/LS3, others), Use all of these methods and you'll never be oversold.

Question.. Long tube headers with a rear mount turbo. Better performance or worse?

[@timothybayliss6680]

Compared to what? Rear mount with manifolds? Headers help NA and will help with a turbo. Sometimes way more than you think it should and sometimes not so much. Headers usually add a bunch in the midrange and that's always good.

[@yolofullsend]

@@timothybayliss6680 compared to manifolds.. ive heard a few people say that the long tubes did worse in regards to spool time... I know Richard says " what it does na itll do under boost". Im just curious overall about how itll react.. will it make more power through scavenging etc..

[@timothybayliss6680]

@@yolofullsend with a rear mount, the length of the header tube takes away from the rest of the exhaust you need to charge. There is very little difference in spool time and I am doubtful of any claims without good evidence. I have heard the same thing a whole bunch. Even guys say short tube headers spool worse than stock ls truck manifolds and the only evidence they have is it feels different. If you look at every racer that has a big turbo that doesn't light easily they all have headers. They all have long tubes that fit the chassis and a really good merge collector. Even for a 36" long 1 7/8" header tube it's 1/15th of a second to charge the pipes with exhaust with a 6.0l engine at 3600rpm. I don't know if you could notice that. Rear mount is a little different only because how much exhaust is pressurized but I really can't see good headers being worse than stock manifolds.

[@ronniedean62]

Great testing and information revealed

[@deonisp]

Was this cam SUM-8711? Please verify, you inspired me to finally do an ls-swap with an l92. Summit now makes SUM-8711R1 instead, I hope it has the same characteristics and clearance. Thank you!

[@rustysausage69]

Yes it is SUM-8711, and yes SUM-8711R1 would have pretty much identical characteristics and clearance (1 more degree of exhaust duration, no lift change). Right at the limit of piston-valve clearance but with the L92 youll be fine because of the dish piston. I wouldn't advise going any bigger than the above specs unless you do a piston upgrade or flycut.
