JUNKYARD (BIG BANG) SBE 5.3L LS TWIN TURBO-MAX BOOST!!

[@chevy383jt]

I rebuilt a Gen 4 5.3 with all stock bottom end components. Gapped the new rings at 32 and 34 thousandths, ball hone. All new heavy duty bearings, including heavy duty cam bearings. Single 98/88 turbo. SEP 100lb injectors and a Holley Terminator Max. BTR truck cam. My truck is so powerful, that I'm having to learn to drive better to handle it. I cheaped out since i don't want to invest money in the old 8.5 10 bolt, and i welded the spider gears two days ago. My friends don't believe that the stock bottom end can handle 15Lbs of boost, so I show them this video. Thanks Richard, for everything. There's a new tuning shop that popped up recently a few months ago two buildings down fromy shop. I got a quote today for basic dyno tuning with the Holley. They told me $1500 for tuning with up to 5 dyno runs. It took some effort to not laugh. This "new" shop charges twice as much as the well established local competitor

[@richardholdener1727]

up to 5 runs? That price should be for a full day of testing-including street tuning

[@chevy383jt]

@@richardholdener1727 I agree. I'm going to speak with the owner to see what's up. The employee may have mis-quoted. I'd like to build a relationship with them, especially since they're so close. I can hear cars on the Dyno from my shop and it sounds glorious.

I would also be down to buy parts from a combo after you test it. Like I really want to to see what the summit 8720 cam is like in an l92 even though it's similar to the GM "Hot Cam" Or even partner up with a company like summit to test parts/combos guys want to run. I would be super thankful to see what a cam and heads can do with a link to a video right on the page. I'd like to see you try 50/50 coolant and stick it in a cold freezer at like -30 since it will still be a liquid for the intercooler. Ice water is always going to be warmer than 0C otherwise it would just freeze.

Hey! Would you ever be interested in testing the horse power limitation of an air to water intercooler for a 6.7 power stroke? Super curious to see how it’d work on a LS!

Can you tell us the afr and timing of these motors and what you consider safe for both of them please. Thank you for everything that you are giving us for free👏👏👏

[@richardholdener1727]

AFR was mid 11s and timing was 20 degree at the top

[@Only1English]

Richard do you or if not have you ever thought of offering built motors? Meaning you can have motors already built and ready to be purchased or you can take an order with money up front of course for a custom build for a customers requested requirements.

[@richardholdener1727]

no thanks

Would love to see this test done on a 360 magnum

[@jaydubb71]

Saw a guy do a junkyard 360 in a 68 or 69 Cuda. Blow thru carb, twin GN turbos. Low 10s. Water injection setup was crazy. Boost referenced from the carb hat (old Banks marine hat) and used an old FIRE EXTINGUISHER as the reservoir for the water. And a 727 trans. It worked. Owner said it laid tire in 3rd gear and rolling into the throttle. LMAO!

Pls do a boosted 300 inline motor. I have one that I have had at 18psi and im wondering how far it will go. If you need a motor you can use mine amd its all set for boost already

Whats done to it sir id love to know what it ran like at 18 psi I bet it was standing tall

[@johnzimburean9304]

@@kevinjohnson9372 its no high dollar motor for sure. Currently it has a ported head with plugs I machined too fill the air injection holes before I ported the exhaust side. It's cammed with forged pistons and arp studs. Single turbo with an ms2 extra ecu. Thats about it.... At 18 psi I hauled ass! With a full truck bed of stuff on the way to the dump I was running door to door with a c6 vette down the highway at 11psi. I have rods for it so I can turn it up more but ive been building a new chassis so its been sitting

Depends what you want. Monster torque, soon as you mat the gas.... Supercharger ! Turbo you'll have to sacrifice a little bottom end torque, but make up for it on the other end.

Do you check or replace the bearings in the engine before you do the big bag test? Just wondering about oil pressure issues at such high cylinder pressures.

[@jimkillen1065]

I always enjoy and appreciate your videos. Sir do think that a set of pistons squirter would help these turbo engines at that boost level.. it's amazing how much power you can make with these turbo engines . That would be a great way to power a boat especially since they have a lot of cooling available. Me and a friend when we were kids had a flat bottom v and with a 302 chev engine we spun to 7500 ..with a set of turbos it would have ran a lot better

Junkyard motor idea- I loved the 1998 Dakota RT when it came out with its 5.9L Magnum. Can you do a series with that junkyard engine?

[@davidpeters1024]

Richard im very impressed in the 5.3 L that u did run on the big bang and made a a lot of horsepower and tongue. Also building a 5.3 turbo motor and been researching like crazy for info on it. i think im going to try to do the same here. Also u said that 706 heads would work just the same if they where ported. Like to pick your brain on this combination

ported stock 706 heads work well-check out the big bang 4.8L

[@troylambert5140]

Actually I think the 5.3 might be able to match the 6.0 Big bang numbers.. despite the smaller size and it might even live a little bit longer due to the thicker bores between the cylinders depending on the cylinder head selection of course and the ability to keep those cylinder heads clamped to the block

[@richardholdener1727]

the rod breaks before the gasket gives up

[@MikeSmith-mp7lf]

Funny enough that I have a LM7 in my 05 Silverado with a single 76mm turbo, BTR stage 4 cam and ported heads, E85. It made 815 to the tires on 12PSI of boost. The only 2 downsides to this is it doesn't create enough vacuum for the power brakes, and the turbo lag is pretty bad. However, I daily this truck and I couldn't imagine how much worse it would break the rear end lose if the lag wasn't there. Just the engine alone is around 450HP so it has no problem smoking the tires, but smoking them at 65-70 MPH will make you "clinch". Its interesting to see a stock bottom end handle 1200HP though. My eagle crank and lightning rods and pistons are only rated for 1800 so GM must have done something very right with the 5.3

[@richardholdener1727]

you have a 5.3L that makes 450 whp na?

I agree, lets see what can be made on 93. Big ping videos!

[@QPC_LLC]

Mr. Holdener, I had a special request. If at all possible, could you do a remote turbo test on one of your engines where the turbos are mounted 10-15ft away from the engine? Maybe show how much wrapping the exhaust or the diameter of piping affects the curve and document EGTs, EMAP and pressure drop compared to an identical front mounted system. As always I truly enjoy just how thorough your videos are!

[@richardholdener1727]

the engine dyno is not the ideal test place for response rate changes

[@QPC_LLC]

@@richardholdener1727 Sir, thanks for responding. I guess I should've worded it differently. I'm not particularly looking for response changes. That kind of test would be akin to trying to test ball bearing vs journal on the dyno. I'm trying to have illustrated the more pertinent information. How much does the loss in EGT affect back pressure? What does that mean for torque production vs top end power? There are a number of people who have done remote mounted solutions. How much are they leaving on the table by moving the compressor so far down the line all else being equal? I think it would be great to finally see that and end the speculation around the internet.
