Turbocharging The LS 408 Stroker - Engine Power S1, E19

[@woodgrain18]

My goodness LoL I've made that kind of power with gen 4 sbe 4.8's and 5.3's with basically a badass hydrologic roller cam and pac and btr valve springs with stock 799's and even some very mildly ported 706's on methanol and with a cats wheel Borg s485 and a billet wheel badass s488 from forced inductions I know the 5.3 was making over 1000whp just based on weight and E.t my fastest pass with a 4.8 with the 85mm 1.15 t6 housing was a 5.57 @ 3200 pound and 5.44 with the big 88mm both had the same th400 butt different ptc converters specced by dusty bradford Holley EFI VP m1 a cheap 102 mm summit brand intake and throttle body and billet Atomizer 325 pounders I got a decent deal but didn't car forem all that much they would stuck open alot more than I cared for LoL I was turning the shit out of both shifting at 7300 and goin across the stripe at 7800-7900Rpm. If I built a 408 with those heads and a good rods and Pistons and it didn't make 1200 plus after The tune was halfway right I would be pissed lol it would definitely be on E90 or e85

Usually they do show the screen... when they don't, you know it was a crap run. Remember, products they show are also sponsors... so they did the best they could... even the company rep split before the final run. The engine also has a serious pause/hicup during acceleration on all the pulls they showed. That set up will eventually destroy a perfectly good 600hp LS, which I believe is a capital crime in some states.

No power is used, however power can’t be lost do to restriction and back pressure so using larger hotside can have huge gains on the higher rpm range but cause lack of spool and boost lag. Turbos like any power adder have +\-. Wheel to housing ratio and flow rate to psi can be a HUGE factor in true power. Love y’all keep up the good work. 2000hp or die

Dude, this was a give away engine. They're not trying to push it to it's limit for someone to destroy it and get a bad rep. It's over built on a safe tune.

The way they came into this series at the beginning of this build really made it seem like they were going to show us what this engine could REALLY do. Now, they did show it producing some good horse power at the end, but I was not really "wowed" by the final result. It even seemed to me like there was something a little fishy going on with the motor during the dyno pulls. I'm not an expert by any means, but I just felt as tho the final result came up a little flat. Especially considering all of the talk in the video about 'how much power this whole build is capable of'.

[@astrawally8448]

Sorry mate, at 2:29 wrong, a turbo DOES NOT work on exhaust FLOW. It works by taking the energy from the EXPANDING gases to drive the exhaust turbine, which are still burning and expanding after they've left the combustion chamber. This is why unlike say a supercharger, there is no power lost because that power is normally lost in a naturally aspirated engine.
