we are about to put the escalade on the dyno at pfi speed somewhere north of denver colorado just i'm just looking at this freaking rig here i hope i hope they let me take a look at that later [Music] i actually have pieces of wood that i put on there and i forgot them in my rv you know it looks fine like that actually yeah i was dang like you know what i'm never putting that back on there you go i never i never even thought about what that would look like with the black lip like screw it is it blowed up that's what a one two one does to a oil pump in a honda civic it's blowed up what is the dyno record for this dyno we've maxed it out before what's that 2 000 okay so we're probably not going to do that today i mean we could sure have to try we could we could try brent says he knows how to use ms3 really well yeah people ever tell you you look like a honda guy some days i'll go out and i'll try and look nice and those are like you still look like a hunger game how that car pulled in that way instead of me pulling and being way over it i'm gonna back in so the front's out this way yep i have no idea what it's going to do hasn't been on dyno since october of last year so not touching anything oh yeah we're gonna we're gonna see what it does all right let's get this thing loaded up fingers crossed we do a good job i feel like a foreign exchange student from another country i don't i don't speak the language in here but we're all in the same classroom bumped out the rear bars because you know as i sleep back there for drag week which i actually came back there last night that is rad i'll be camping on in race week too this is cool are you going on the second race week yeah i am oh cool we'll see you there oh yeah we'll be doing it in the deal truck so oh man it's going to be cool i've never actually heard this thing get run from outside so i'm pretty pumped to see what uh what it sounds like yeah this is exciting hopefully my own drive shaft doesn't take me out i don't have a loop on this thing it's a really long drive i'm gonna get crucified for that [Applause] oh boy i'm i'm really excited to hear this thing from outside the driver's seat because you know your car always sounds so much different from the outside than it does when you're in it brent knows what he's doing with the ms3 stuff so he can go in there and do some magical things this thing probably really needs we've got soccer mom super bowl escalade minivan we're gonna find some more all-wheel drive suvs and vans i'm all about it just have a big drag race against all of them that'd be freaking sweet what 13.50 whoa yeah this thing is like just going going wow yeah don't you just hate when people come to the dyno and their stuff falls apart it's everyday i'm cool with it it's kind of fun right about to go full orthodontist on this thing who's stepped in that who lost their shoe you know you're defeated when you just leave it there they're filming a video too so i don't want to film at the same time necessarily they're filming all the time so you gotta go watch their video to see that stuff dude i taste blood i think we need to keep going holy crap my god that was unreal i can feel the whole thing in here too man 1492 with the tire it's 90 something degrees in denver dude are you kidding me this is a monster a legitimate bonafide monster how much boost did it make i smell blood now i think we need to keep going 22 pounds on the spike and then uh fell to 15. so the spike is where it peaked at power wise yes so 1500 at the tire on 22 pounds of boost yeah in denver bro in a six thousand pound escalade yeah oh my gosh you realize what you're sitting in right yeah you have navigation right there bro do you want to plug in the aux cord turn your cooled seat on is it too hot in there for you right yeah i got the air conditioned seats yeah it's still an escalator this ain't no strip down no this is still a luxury vehicle oh my gosh this thing is out of hand wild like we could take this thing to dinner you did one night went 191 on the dyno okay so don't give too much more my gosh dino jet won't let us go above 200. bro like bro we're we're doing something here we're doing something this is noteworthy material it is no worthy material i love that we're flattening the curve yeah what'd you say the da was right now 15 791 feet d a and we just made 1500 of the tire yeah so we added more duty cycle out the back and it carried it better but that duty cycle didn't change so we're still around the same there but you can see it's getting it's getting close to there oh yeah that thing just holds all the way to 195 mile an hour you ready i'm ready are you ready i'm ready do you add a little bit of duty right to the right to the hot spot we got a little duty in the hot spot little dude in the hot spot all right i trust you i trust you too did it push the door open you guys are rattling my toolbox over there the exhaust is way up here and it pushed that door open the rest of the way yeah what a ride brent wanted to put a light under here when we had the camera down there i'm like that's not a good idea that is some exhaust pressure down there how'd everything look fuel wise oh beautiful really yeah the tunes on the money on that stuff that's crazy because this has almost no like literally one tank of e85 up the highway down the highway that's all the more timing and everything that's gotten in it has been just consistent on the same path every time 23.23 pounds and then when i let off it was still at 22. oh cool yeah so what what rpm was it at 23 pounds at 23 pounds was at 60 66 600. that's not even doing anything yet yeah dang that's like when i shift it's like down there let off at seven thousand cause i figured you like you said it's just following anyway so yeah what's the point we're getting the number there we just yeah we're doing it for the gram anymore and i still went 174 miles an hour according to this so 23 pounds it was at like 22 point something so not even a full pound increase made 40 horsepower yeah so this thing's still well within its efficiency range yeah it's awesome this is great this is great man good job thank you you put it together really good parts and it shows like this is this is excellent i mean i was just like the the general contractor on this engine stuff like i just did my research and picked the right people to specialize in the right components to point me in the right direction i just made the pipes and wired things ignition timing was 13.8 that's it that's it nothing nothing at all i almost wonder like how's that even possible make that much power on 23 pounds of boost this thing has to be moving air so effortlessly a ton of air a lot of air so you think we should uh give it a little more and see if we can touch 1600. it sounds great to me i like this guy me too i mean heck we're not even throwing beans out of you here's one ton of boost all right we're gonna make you proud dad you talked me into it yeah we're gonna be like 1600 at the tire with 24 pounds of boost like you're a freaking lion no way no way that's impossible keyboard warriors commence you can't do that you put together one heck of a program here 1600 coming right up it's getting a little toasty at the end of the polls here it's like 90 something degrees outside and that fan there isn't super huge so we're putting another one on there i've been banging my head on this thing all day and i finally fixed it just just little things you know dolph guy problems 1776 1776 wow wow i did not expect this today today is a good day hey brent you think we get another 50 horsepower of this thing without much more effort you know we could dude i was thinking to be like 1603 like all right we did it like we're good but six 1650 five pounds that's only twenty five pounds we need thirty yeah we need thirty did you add a little bit of timing to that spot too i did still twelve and a half degrees really it's because you go up and boost it drops even more yeah a little bit so if you give it a couple degrees and a couple more pounds a couple hey a couple degrees at that boost level i think that would get it because 12 degrees is nothing nothing that's nothing this man is a bad influence right here over there that thing sounds like freaking gravedigger had a kid with a cup car like it's just rolling 1650 horsepower 1235 foot pounds of torque at the tire [Music] dude we just put down 1700 horsepower at the tire it's going through a nine and a half inch 14 bolt rear end a 4l80 and spin in the transfer case too and an unlock converter we could still add duty to this and get it to carry like it normally makes peak power higher than this but we're just freaking we're just pimping here so we're just putting where it's making it and not spinning the motor line them up oh it's happening it's going down dude soccer mom super bowl coming at you we just got to find some more guys with some off-the-wall sleeper stuff like this get a whole big thing for it yeah i know there's a lot more sleepers out there so yeah it's like what i live for i love these things dude it's so much fun especially like i love this thing's all-wheel drive if you got a sleeper along these lines and you want to be involved in this make a video make a post hack us both in it um i'm stapleton42 what's your at if they don't already know it can be boosted boys or boosie boy kyle from my personal yeah put it up either one of those we'll dig through him see who's good and we're gonna put something together
