What happens here
This project details the process of testing and tuning a custom-built truck at a drag strip following an intake manifold upgrade. The video captures the challenges of testing in adverse conditions (rain, no-prep track) and the iterative steps of diagnosing issues, making adjustments, and analyzing performance data to optimize the truck's power and traction.

(18,819 characters)hey suck it nerd four wheel drive let's be loading the rain those are not zip ties when they're there permanently they become lightweight race fasteners what are we doing today dylan see if it runs with this new intake on it just see if it runs we're gonna hope and pray it runs but we have the entire track to do whatever the heck we want yeah yeah um just us here today there was supposed to be a rental but being florida like it is the rain comes and goes as it pleases so rather than have folks drive a couple hours they uh just said if you want to go after it if it rains you're on your own you're doing some no prep testing on the probably the return road or do you want to use the actual track um we'll probably end up doing both depending on how well it runs um i would like to make sure that it at least does what it's supposed to from this end and then once we get that working and the tune-ups happy with the new intake and stuff we'll actually try to make it do things on the other side i want is pretty much as close to an apples apples comparison as i can from the last time i was here at the track from intake to intake now it's obviously no prep up here but there's still a substantial amount of rubber and that's not usually an issue for me so if we can get a quick apples to apples and then we can start playing with it on the other side so he just swapped from a stock uh like truck intake with a tbss intake through the holley hi-ram and the tuning has not been touched yet so that's what we're going to work on first is seeing what it needs and what to change because it doesn't run that great right now he said he would let me take it for a rip which i'm pretty pumped about almost there ah will it not start in gear uh yeah i could that's what i do without a neutral safety point you will yeah no one heard that so this is like a whole big process here and he really doesn't like it so we're gonna pretend that he can't hear me as i show you guys how horrible this looks are you having fun yet all the fun every time i told him he should just hole saw into the tonneau and jb weld the jar like a cut to our peanut butter or the underside paint a lid black and then you'd have like a perfect funnel receptacle you could then you could put like skippy on your country rocker find some jiff on there like when it didn't run i'd have something to eat yeah that too so he just put it back on like wastegate might make like nine pounds we really don't know what it's gonna do but it's gonna do something oh well i mean you want no prep this is no prep that's more no prep than i bargained for so we may have to do it on a return road i didn't even think to come look because that's way more water than i'm driving on it's fine it is some radial pros without any sun to dry it i'll just do it on a return rib all right change of plans i guess we're going to the return road so we moved down to the shutdown we're going gonna run the track backwards i think it's cooler down here anyway it's definitely more it suits the bill of what we're gonna do with it so this is great for those yeah really like mine hooks up better on bumpy stuff like this than it does on a cold track oh yeah like yeah i haven't made the hoosier spin on the street but i'll spin on the track if it's cold yeah well the track's one of those things so it's like it's has more traction than you could handle until you lose it and then it's gone yeah there's no recovery whereas here even if there's a slight amount of wheel speed you can kind of whack it keep going yeah it's just like running on sandpaper yeah when your stuff's so heavy it picks it back up yep so it's a plan here just going to get in it and see what happens yeah make sure it's going to run good on gate make sure everything's happy it'll make a pass under power trying to make sure that front dip is locked in our zip tie didn't hold what happened dale didn't hold the zip tie didn't hold where's the rest of the bundle right there oh okay yeah we'll pop the hood it was like i was kind of rolling into it just like watching everything yeah this throttle cable here giving us a little bit of problems so we're just like oh we'll just zip tie it to the that fitting but it moved so maybe we could throw another one on the fuel rail maybe because that's safe yeah because it's this piece that's really the easiest oh it came out up here oh shoot that wasn't oh okay what the heck doug buy your gm bracket and it doesn't fit the gm cable i blame doug cook no it's not doug's fault no operation operator error honestly it's okay you got this you don't need our help well i think it's i think it's working give it give it some more yeah i think we're all right all right so zip ties are in place we're gonna try this again [Music] it worked it did not look fast but it worked but that was only like wastegate pressure which is nine pounds or maybe even less we'll have to see so it looked like it worked yeah it was lazy but she went so i think that was only like around eight pounds i was trying to look at the dash but eight pounds on a stock five three so that would probably make about like 500 ah maybe maybe yeah maybe that might we got the teeth knocked out of it right there so that way like when i ride on pump gas i try to set my wastegate spring up so that way pump gasses are our wastegate spring is pump gas friendly so then it's like you can't hurt it like i could put a brick on the pedal and walk off and it would be fine so driving around is supposed to be fun so like i want it to be bulletproof in that condition it doesn't i don't race under those conditions so it doesn't need to be fast so adrian's here with the competition back from the dead you want to uh you want to line this up against old uncle rob back there listen uncle rob may want to have a food eating competition but he does not want to race see that intercooler in the front you know what that means yeah got a i bet you that thing has no problem keeping up with iats it's got it's got bluetooth cold stuff bluetooth gold side nice same especially nice boost wise it made a max of 8.3 just about like what i what i figured maybe we can turn her up a little bit more that's what i like to hear so the draggy did work yeah i had no idea i never used it before i was kind of excited to try it out but it did pretty much just about what i expected a little slower but that's probably due to some tune changes and stuff but 179 60 foot like just cruising off of a low two-step low boost launch so if i if i had pulled up to the track and and you would ask me what i thought my 60-foot was going to be with what i had in the truck i'd have told you 174. so considering an intake swap and some things that i never even ran before that's pretty on par and it's a draggy yeah like that's a bottom line it's an accurate number yeah you can you can trust the draggy absolutely so between like my estimation and draggy and lots of experience running the truck it's pretty much really close so what are you gonna put in it now um basically i'm just gonna go straight to double so i'm gonna just pin the three-port mac at whatever it makes so like probably high teens 17 18 you see do it whatever it makes it makes if it dies he dies so you laugh but i literally said that about five times in my last race because i drew a really really fast guy at the snow prep and i had no clue what i was going to do to beat him other than go as fast as i could so like i swapped some things around and i basically turned my freeport mac valve into a check valve so the wastegate has a top and bottom port while i pulled the bottom port so there was nothing to helping the gate open and then i plumbed the top port directly to the dome so all the boost was going through the dome nothing was helping it open and it made like 30 pounds on the trans brake so like i moved about that far my map sensor was pinned it was maxed out it's pretty much a hundred percent through all the places that's a throttle position an rpm graph and that's duty cycle to the mac valve so it's 100 basically everywhere 100 percent it give it one hundred hundred it's about to start raining we gotta get this rip in we're gonna hold up in the rain i'm gonna leave the rest of the rain we gotta descend and turn in the rain all right it's good it's fine ah well now he's just putting on a show you know he he just left that on purpose just because i made a good video and i would have done the same thing i forgot to put it in four-wheel drive i'm an idiot and now it's raining that was a waste dang it i'm stupid i forgot four-wheel drive oh that was two-wheel oh man i know they've been so much cooler i left and i made it about that far and i was like um i'll do a 60-foot hit real quick all right let's see what it does so we forgot four-wheel drive there's water on the ground and he's just gonna do it anyway is the draggy on uh yeah it was on let's see what you can 60 foot in the rain all right i gotta reset all right 60 foot in the rain floor to man style here we go [Music] [Applause] [Music] now that was much better yeah i didn't get to get a full headache because of the rain and the short track [Music] that was the way it was supposed to go all right that was worth it now we can pack up everything's okay that's pretty good a little bit as those front tire was all like that see if i caught that that's a dang good launch for being in the rain catch the doing the old cabbage patch oh yeah it's like we're turning left we're turning right let's do a turkey well obviously now it's raining and we're kind of screwed now it's really really raining they suck at nerds four wheel drive lets me load in the rain so rain aside how did that feel so i mean it spun pretty bad when i actually remembered to put it in four wheel drive so that was the first time i'd ever forgot to do that by the way like ever ever since having and racing this truck that was the first time but that felt pretty good i'm not disappointed in that at all it spun pretty bad and the front end had some action but it's started to rain on a no prep with no rubber no burnout no nothing just dead asphalt out there cold tires we hot lap the truck and the fact that it moved at all and did some substantial things is good because that lets me know that as soon as i get on a track that is any of those things like it has any rubber down any sort of glue anything else at all i know that that will work that's a very good starting point to go from now if the track's worse or better i can make the changes necessary but that lets me know that what i left off of what i use right off the trains break is going to be a good starting point whenever we go to actually race somewhere when i let go of the button it was at 5000 rpm and right at 13 pounds it made it up to a peak of 17.9 so yeah just about what i expected i didn't know if it would end up right around 16 or if it make its way closer to this 17 or 18 but yeah it made it's all the way up to 17.9 was the peak that's right when i lifted it's about halfway through second gear did you have the draggy on for that yes i did let's see what your 60 foot was in the rain so it was spinning like i said it was spinning pretty bad so that was a 163 spinning in the rain on a no prep 16360 foot what was your does it say zero to 60 on there um yes 0 to 60 was 254. two point five zero i don't yeah i don't know what that metric is i don't know if that's fast or slow but that's what it went that's fast i mean i think like a stock new gtr is like two three or two two or something not in the rain yeah i wonder i'd have to check like one of my track times see if there's some kind of math i can do that or run the draggy on attract time because it's got to be way better there is on like the wallace racing thing oh they have a calculator for it yeah well i mean i've been like on a regular track side a bunch of 140s now and i don't see any reason why i can't go 130s like absolutely the reason i was slowed down at 140 is because i ran out of horsepower like i feel like i had enough traction in the first 10 feet to go 30s maybe even on an extreme circumstance a high 20 i'm just convinced that i can but it's between the like 10 foot and the 60 foot mark that i'm just out of horsepower like i don't have enough to continue accelerating well that didn't exactly go as planned but that's florida florida has a really good governor but really bad weather spotty you know it's not raining anymore six miles away yeah it's still raining over there probably yeah so yeah i live six miles from the track and it is not raining here and doesn't even look like it really has no it's still dry you're right it does not look like it's rained here when i get spicy in the road with it maybe i'm all about it we'll see if we can wake harold up one more time yeah harold where we're coming we're coming harold but wait there's more what i thought it was on fire but it's just steamed oh it's just steamed oh we're good good it's like a relative term like may not be good but it's not on fire i know you can't smell that but you can pretend you do all right let me just yell at myself then as you can see i don't know if the gopro picks it up but when i do that we are basically pinballing off on both sides of the road this thing is so tight no it's not it's just doing a little bit of wow so this thing has a very bad rack joint these trucks are notorious for that have you ever ridden in your own truck before not really this sounds way different from the scene versus that one cause the exhaust is like i don't know it's just a totally different sound but it sounds freaking spicy up there like not what i'm used to hearing i mean it's not as crazy over here but i'm not used to it over there either yeah and like i don't know if it's just the intake again like now i'm hearing it without my helmet also it's a difference but like i feel like it sounds a little bit more radical now than it i remember riding around in it yeah just like total tone i don't know if it's the intake the passenger seat or what's totally different [Music] it was like not really doing anything yeah so the gopro on the windshield was the six um adrian's gopro six on the suction cup and i'm filming with my eight now i had the eight sitting in here and when i got out i couldn't find it because the insane g-forces flew it out of the dash well it did it flew out of the dash so you don't put anything that you want to keep on the dash if you want to keep it you just put it against the back seat because or like the back of the cab because that's where it's going to be anyway it's okay dad i got it i got a headphone yep all right wow it's still there there's no holes in places so we did all right it's still there is there oil on the ground i don't think so nothing i didn't break it i don't think we broke it so when montana drove it he did break it no he didn't break it we thought he did like he made a loud pop and like all of a sudden the steering was all freed up and we were like that's weird but i never found anything wrong with it so the zip ties hold up yeah they did no those listen we talked about this those are not zip ties when they're there permanently they become lightweight race fasteners and that's the intro right there yeah look holy that's why i didn't drive right oh there we go well jesus come on he noticed i had to put it on the trailer it went somewhere else crazy like oh this thing doesn't make any power i told you i was like i don't know if it's in the wrong gear it was just slow like i thought i was in i thought i was in second gear because yeah i i was looking at the shifter i'm like no he's in the right spot i don't know all right well i was just about to film the outro here so we'll just do it rewind real quick all right this thing this thing was a lot of fun to drive even though and then it wasn't yeah i kind of broke it a little bit i mean it's nice to say that i broke it and it was just that it's just yeah you know i didn't i broke it but i didn't really break it you blew it you blew it i blew it i blew it up but not up we blew it but not up no you just blew it just blew it off but yeah this thing's freaking cool you gotta go subscribe to dylan's channel uh right here dig in z71 it's the same on instagram and um youtube yep yeah he's uh he's been out there grinding and punching through the youtube algorithm because you know when you've got a tiny channel it just does not want to help you get views for the longest time as i get mobbed by a moth about the same place i was at when i was back here in june did the first video about this truck which explains the whole backstory this was his grandpa's truck his grandpa bought it new drove it forever dillon beat the crap out of it as a mud truck and somehow it evolved into this but if you want to hear all that story you can go way back on my channel feed and see that one but you gotta go to his channel and check that out because this man is full of a lot of information one of few people that i go to for perspective on things like this yeah because there's just not a whole lot of us doing this stuff yeah so i mean so i pretty much this entire story of this truck has summed up with like do more with less it's always been like over traction and underpowered and overweight compared to everything that i'm racing so i have to make best of that and that's been the strategy all along and finally i'm making some horse torques to do more llama thrusting i remember you're just having all kinds of problems with this thing you were messing up motors just as often as i was messing up transmissions and then suddenly it just seemed like earlier this year everything just clicked and you just started little pieces started connecting where they needed to be you just started kicking ass out of nowhere yeah well i got you know i want to call it lucky but like we won a couple of weekends in a row and until last weekend i had won like my previous 14 pairs i had 14 heads up pairs of racing i had won until last weekend there you go go check them out hit that subscribe button here too if you're watching this and you watch this far and you're not subscribed to me i don't know what you're doing you're doing it wrong you're doing it wrong make sure you subscribe to me leave a comment if there's anything you want to know about this truck um i will make sure that he goes into my comments and answers your questions so you're very good about that all the forums and stuff so check it out make a comment ask questions good questions bad questions he'll tell you his favorite color you know what his first dog's name was any of that stuff doesn't have to be about the truck he will he'll talk to you so we'll see you
