0-70mph & 16psi Boost Modified Turbo 6.2 Diesel

[@rangerismine]

Looks like you’re about to fly into space from all the gauges.

[@TheAscendedMaster]

@@rangerismine lol and still need more.

[@kamikazekunze]

Damn, I would have loved to have that in my M1010. 😂 nice build.

[@PeytonRader]

I’ve got the m1008 cucv with the governed injection pump. How significant of a change is it by running that db2 with and without the turbo?

[@TheAscendedMaster]

@@PeytonRader It was a complete night and day difference, like an entirely different vehicle. Tons of power and tourqe compared to stock. Cut my 0-60 mph time by 10 seconds! Getting just as good fuel economy too even with it Turbocharged and the fuel up.

[@fmagalhaes1521]

@OracleGrower, was your truck military surplus originally? This looks like a good platform for a suburban.

[@TheAscendedMaster]

She's actually a Canada made 1981 K20 6.2.

[@gentilejoshsaved1646]

Awesome. I want one

[@celloprof]

0-60mph in 13seconds? Not bad. For what my pyrometer shows in my 6.5, I dont think I want more than 15psi on the turbo. I still wonder if my trans is working correctly.

[@TheAscendedMaster]

I'm currently at a 10 sec 0-60 loaded and can get down close to 6 empty. These trucks are very underrated and all comes down to proper maintenance for longevity and reliability. 15 psi is alot on a stock GM Turbo back pressure wise. I regularly run 15-21psi without any problems but my engine is upgraded to handle it.

[@Jean_1999]

Bet this thing feels like a rocket compared to a stock 6.5😂

[@TheAscendedMaster]

She's a quick one and even quicker than in the video. I can get down to 6sec or under 0-60 with all the weight out of her and pump cranked up but the tranny needs rebuilt. Im currently at a 10sec 0-60. She also weighs alot and am at 6500lbs and was heavier in this video.

[@bbtjdonnelly14]

How big of an injection pump, cc's?

[@TheAscendedMaster]

Slightly turned up DB2 4153 HD

[@SparkplughunterIDI]

What Injection pump are you using?

[@TheAscendedMaster]

DB2 4153 HD turned up 3/4 to a full turn.

[@supchief8673]

What would you estimate the horsepower at

[@TheAscendedMaster]

I'd say w boost set to 21-25psi she's probably 440-500hp but set @15-20psi more around 350-420hp. Guessing of course so only a dyno can tell for sure but comparing to my mildly built 454 I used to have she's faster.

[@cadorseeliger3926]

That's gotta be the biggest numbers I've heard of out of a 6.2. I've seen plenty of 230hp hx35 builds.

[@rock-uu7qr]

@@TheAscendedMaster you arent making 400 hp on a 6.2 diesel with 20 pounds of boost. My 6.5 spiked at 19 psi with my super 60 and I was probably only making 270hp

[@TheAscendedMaster]

@@rock-uu7qr lol Well you don't have $45k into your truck like me now do you? The only thing stock on my engine is the block, cam, crank and pistons. Everything else is new, upgraded, modified, ported, polished and aftermarket so to try and compare your truck to mine is just not realistic.

[@rock-uu7qr]

@@TheAscendedMaster Not trying to be a dick but why would you keep the stock crank. That is the most brittle part of a 6.2/6.5

[@k30mtb78]

Are you ever gonna Dino test it?

[@TheAscendedMaster]

Probably but gotta get the tranny rebuilt first.

[@jamesbuck555]

OOH MY😅

[@rrf8185]

Swap in a nv4500

[@TheAscendedMaster]

Unfortunately due to my ailments in my body I just don't have the strength to work a clutch and shift constantly.

[@fmagalhaes1521]

@Oracle Grower. How can there be too much power? :) lol. I need to go find your videos of how you upgraded your engine.

[@TheAscendedMaster]

The drivetrain is completely stock and with 450+ HP and a already bad slipping TH400 she can't keep up with the extra power & tourqe. I also carry around 2000lbs in added weight from my tools, camper, spare, hitch and other stuff in the bed so shes always working harder than she should. If I completely emptied the truck of all the added weight she would be a freaking turbo diesel dragster lol

[@mardellgriffin7276]

It's not made for power like a car, 15psi should be the max
