I'm going to need 20 more videos where you mention ring gap because it still has not sunk in yet. I will probably need my own Big Bang before it does. Every cam is a turbo cam is finally sinking in..... Thanks for not giving up on us stubborn ones.

Couldn't agree more

[@000martin3]

It will happen. And while you decel blowing smoke from a ringland popping you’ll kick yourself over and over. Ask me how I know

[@danieldeweese8749]

My understanding is that ring gap is a free "mod" you can do so you dont trash your pistons. Cuz that's expensive. It will burn a very little amount of oil but not enough to matter due to blowby is my understanding. It's a trade-off that is worth it.

I'd be interested to see a test of low boost with high compression and low compression with high boost. Like 9:1 on 20lbs of boost, 11:1 on 10lbs of boost

[@fastlanez3000]

Yes please

[@Borderline5440]

My money is on boost. 10 pounds will nearly double the output of a motor. On the other hand, even minor increases in compression can have pretty dramatic effects on power. Richard's video on 706 heads (higher compression) vs 317 heads (more airflow) is a perfect example. The 706 heads made more power all the way across the board.

[@l8tapex]

My self. 6.0 from 10.5:1 to 9.2. Exactly 20lbs boost with a T76 for street daily.Just siting have yet to fiinsh front end.

[@turbotysen]

OR just do the test at the same boost level with each engine and show the benefits/ differences of each! that would be an awesome video! By the way, still waiting for a test video on hot side pipe sizing for turbo applications....

[@knowbull5hit590]

Kimbal Mackinnon the engine with more compression will spool quicker. Both motors will be capable of the same power with everything else being equal. With the exact test you mentioned the 9:1 on 20psi engine will make more power, but who cares because the other engine can make the power quicker and can still make the same top end

[@Thegoose95]

I've opened up 3 separate gen 3 5.3s and the ring gaps have been ALL .015 top ring and .017 bottom ring. One of them even had 302k miles.

He has done bigger cube, they respond pretty much the same. just from a higher baseline. So if a 5.3 is 300hp NA and 600 hp boosted then the 5.7 will be 350hp and 7000 hp boosted.

Thank you very much Richard. I'm only beginning my journey of learning all the mad scientist language and what all the different specs mean and all the terminology. I'm new to all this but I understand all of it in the general sense. I'm just a normal back yard mech but I'm learning a lot watching your videos and others. I have a 2003 z71 avalanche with the 5.3 ls. There's so many things I want to upgrade on the engine. Your video touches almost everything I was looking for in a single video. Could you make a show on what happens when you have a stg2 cam, cold air intake, ebay turbo, and long headers with straight pipes? I know I have to change the springs and lifters and injectors and it will need me spark plugs all of which I was going to have to take it to a shop to be cleaned up and tuned up again anyways.

Could you do a test and show what the results would be if the turbo is remote mounted like 8 to 10 feet from the engine as compared to with manifolds and a y pipe like this video? If you do i would love to see the charge temps, lag and the likes. Thanks, Richard your videos are Awsome.

[@ArchimedeanEye]

That would be an awesome test, but I suspect it would make little difference on the dyno here since it's wide open throttle and under load.

[@randywilliams4325]

I have people asking about doing turbo ls installs and the hardest thing to explain is how many mods you have to do to make sure the fuel system can keep up . Like running bigger fuel lines and figuring out some kind of pump system . The fuel system can cost more than the turbo.

[@nopleaseno2515]

Lines don’t get any bigger then stock. You’ll need to up the pressure. Pumps aren’t to costly. Many KZbin videos on the subject. My upgraded system cost so much just because of the unnecessary AN fittings and lines upgrades I made. Otherwise, pump, regular, injectors, line filters. In my case did cost more then an eBay turbo for sure. Cheers

[@thetriode]

Something I didn't catch mentioned in there actually has nothing to do about the engine but the infrastructure around the engine; I'm talking the axle and transmission in particular with secondary on suspension. Having an E85ed LS engine is a heck of an upgrade for a lot of chassis. Also awesome way of collecting thoughts on this. It's something that seems to have a lot of precedence of working very well around it. There's a reason it's common.

[@rexmedina4561]

thetriode agreed, I’m working on suspension, trans or rear end whichever chance comes first, THEN the engine. I’m looking for 700 hp lol

[@Abreezeducttesting]

I've watched all the videos and this is by far the best.

[@fitzeesfabrications]

Very cool. I had a combo in my head now for awhile and a turbo in mind as well. This setup you done is very close to what I had in mind. Very pleased with the hp numbers. Was wonder how the gen 2 would work on a 4.8. Seems to take the boost well. Very cool video thanks for taking the time to make it.

[@bdugle1]

Boost curve? Back pressure curve? Timing? As someone else noted, it didn’t follow the boost power formula... Still, love this channel! That Summit stage 1 cam is amazing! Comment on CR: I think you said once the JE pistons had a 7cc dome. If true, that’s almost a full point of compression, 10.4 vs 9.5. On a 400 hp combo, that should be worth 15 hp or so NA. That makes a difference. I also vote for the meth injection camparo, 91 octane and say 15 psi compared to E85 (which is nice but hard to get day-to-day). Maybe move the meth injector farther away from the throttle body to perhaps get better distribution? You’ll have work for another decade, I think!

[@kyleorsak]

Richard do you /or will you ever do a test with 93 pump gas and water/meth as an alternative to running e85?

First , Richard I enjoy all the content that you have been putting out. Great stuff. Love killing the myths! Lol. Now for my question. I understand that the cam is the brains of the motor but the supporting stuff is important as well. So here’s the combo I’m attempting. 5.3 , 706 heads , truck intake. 4L60e. And it’s in a truck. I daily drive and tow once a month. Years ago you did a test on a camel that made power and torque everywhere in the curve over the stock cam. I can’t find that test. Second. I may have to remove my 706 heads as possible coolant leak in casting. What do I replace them with? Another set of 706 ? Not looking to rotate the earth just a healthy daily driver Your thoughts. One problem wt the computer is it’s much like on line learning. It’s only presented one way and no questions. I’ve noticed you seem to answer questions. Thanks again for your efforts.

"If you're gonna upgrade the cam. You need to upgrade the springs" May I suggest upgrade the rockers to a roller tip. I couldn't find out why I wiped out the trunnion upgrade. I had plenty of oil... I talked to Kenny Duttweiller and he said the stock rockers cannot handle anything over .600 lift. The arc of the rocker was designed for .550- .565 at most....

There are thousands of 600+ lift cams on stock rockers, I doubt that's the problem.

@@thomaslane8944 It was an issue in my situation. Kenny Duttweiller has seen a lot of failed stock rockers at higher lift. That's why I listened to his advice and went with the roller tip rockers.

It doesn't get old but there are variations we would love to see... Like the pump gas & water/meth suggestion. I'd love to see pump gas in the engine and e85 with the nitrous.

[@philistineau]

Richard, the Summit 8720 218 outperforming the SS2 is pretty impactful to people who default to a 23x cam choice. I’d really like to see you fill in the gap between the 8720 and a BTR torque cam. Please see if you can get Summit to give you a 209/217 high lift truck cam. If that performs great down low while giving strong HP like the 8720, it could be perfect for a 4.8l street/strip motor - not race, but partial throttle would be great.

[@thegrandpumbaa]

It's easy to find the torque curves. They cross the corresponding power curve at about 5353 rpm. Even without color coding, this would be the case. PS: the torque curve will be lower than the power curve after 5353, and higher than it below 5353 rpm.

When it comes to ring gap my problem is that I have already installed the engine completely into the car. Everything on and hooked up. Id have to completely remove everything and tear it completely apart. SO...This motor gets no ring gap. The next one I'll be building in the mean time will get ring gap.

[@ArchimedeanEye]

Yeah, I agree but it wouldn't be too bad if you pulled the engine, pull the heads off, oil pan off and just knock the pistons/rods out and gap the existing rings. New head gaskets, re-assemble to spec and re-install. Problem is, we all think it needs to turn into a $5000 job with new rods, pistons, studs, oil pump etc. It could be done and wouldn't be that painful if stick to the job at hand, lol.

[@Ugrasrava]

In some places. Some states (and pretty much the entirety of Canada) E85 isn't available at the pump, and buying it by the barrel does a real number on the cost effectiveness. Still worth it for a toy IMO, but on anything that gets lots of miles, 91 and methanol are a better solution.
