We're in a mustang right now going into . to bmw i know it doesn't make sense . it makes perfect sense actually take the . most boring a reliable car to go tune . the most unreliable fun part i'm just . kidding shelby you're not boring seeing . as a car is going to be pushing like in . the high 20s for a boost well let's just . say big boost himself had to come . because the boost is very big hopefully . bigger than it ever has been before and. hopefully consistent we don't want just . big boost we want smooth boost because . before we had a radek this right big . boost by the side through all once we . get there we'll go over kind of what we . found the problems with the bmw were . [music]. chris long time no see . hey all right i know there's like a . million different things with a car that . are new when i kind of go like a brief . rundown on everything that you guys have . done over the past month . yeah so you know we started taking a . look as we were noticing some weird . issues with bass and so we started . taking a look at some of the components . we actually went to a new tl eval or . sorry wastegate and we did grated . stainless back lines to the wastegate . and to the boost pressure on the turbo . and then hand fittings everywhere i feel . like we should probably mention that the . wastegate was leaking and that's like . why we had all the issues yeah yeah yeah. so that seems to be the culprit is the . wastegate was faulty and it was leaking . straight out of the cylinder so it was . just causing a boosting and it was . really hard to modulate boost with like . that so can you like give a little bit . of explanation how you figured out that . the wastegate was bad because that . thought was pretty interesting . yeah what i did was i was able to take . the wastegate off and then i used a . vacuum line with like an attachment for . like a compressor fitting and i applied. pressure to it and right around 20 . pounds with the wastegate springs it's . supposed to open and if you maintain . with 20 pounds that should stay open but . what we noticed was that it was actually . closing on itself meaning that there was . like an air leak so we actually put in a . bucket of water and repressurized it saw . that was leaking from like the o-ring . for the plunger and just you know . diagnose from there that it was just a . faulty wastegate if you guys don't . remember the car was having issues where . i had like very erratic boost and it . would like make boost and then goes sure . there's no fun and it was like a tuning . nightmare yeah yeah hard to tune hard to . drive i looked in the computer we've had . 38 pulls on this dyno oh my god isn't it . crazy we've spent so much money on this . dyno time other than that solid tranny . mounts i think said they're delrin yeah . they're delrin training mouse they're . just as hard as you can get before you . go to steel so it makes the car have a . lot more training oice so you can kind . of hear the synchros which i think is . cool for me i just like i don't know if . you guys remember when i was driving it . on the track you could see the shifter . shaking back and forth a little bit . which was kind of an indication that it . could use a little bit of enough . especially because we do have like half . of the motor was unlike more like a . solid mount like a car exactly exactly . what the motive kit like comes with a. different engine mount yeah sounds like . solid mount on one side and then a good . you know rubber mount on the other so . now we got delrin one of the big things . we did - was the oil cooler that we put . in the front bumper so it'll keep our . temps down when we're on the track and . dog in the hell out of the car. yeah the only really issue with this car . and the track was that the oil temps are . getting kind of hot it's just like a . known thing even though this car does . have the local or some 335 zone you come . with or boots yeah the 2007 the 2007 . models don't come with the oil coolers . so you have to like upgrade or retrofit . and i see that actually at 2007 we had . one come in the fan on this guy's car. wasn't working and it was running like . above 250 like normal operating that was . just kind of ridiculous so i told him . like you know you need to upgrade if you . have a 2007 model guys upgrade - oh yeah . i think correct me if i'm wrong i think . the 2007 sport packages came with an oil . cooler possible i think i think or like . the oh eights didn't come with an oval . or let's just i know the sport package . add something to the royal cooler for . some of the cars yeah other than that . what else what else is everything else i . know that i'll show them the trim in a . second yeah the trim school all new . under tray since they all like ripped . off 160 i bring oh and then we did some . atv oxygen sensors provide by motive so . they've got like an extra ground on them . and i think they're just better built . for like running ethanol yeah cuz mine . like they if you use the factory ones . with this car they just keep going bad . when you have the single turbo i think . is from all the extra heat yeah yeah so . at least the atv ones as jake told us . you know they're supposed to work better . with the kit . supposedly the car jake when he was . looking at the lodge for the car from . motive was saying it schools about 700 . rpm sooner now which is huge yeah like . if that's true then this car would be . insanely more fun around town yeah as i . was saying about switching to a smaller . turbo big term was good yeah i know but . i like unzipping around big turbo big . power yeah but coming out of those . corners at sebring those coming up . there's also a shop right down the . street called carbon wraps and while the. car was at psi they stopped by and they . wrapped my trim in gloss black and did a . really nice job . do you remember it was kind of like that . brushed aluminum and i wanted to change . it to black so now we've got black trim . look at that . carbon wraps there's really really good . work they're super well known around . this area . oh berta what do you think in the bmw on . the dyno is the boost big enough for you . yeah. let's get in there i think it's that . like a little bit over 20 psi yeah i . think we're gonna go up to maybe around . like 28 no that's pretty big boost for a . stock motor . [applause]. you hated i think we should just go . train 240 pounds yeah he says the boost . isn't big enough let's let's go let's go . until we start having a lot of timing . corrections and then we'll just dial . back from there yeah i think it'd . probably save a lot of time to do it . that way yeah just add add more boost. until it starts making weird noises and . then knock knock who's there how do you . know the limit until you find it right . i'm saying . [music]. jake from motives tunney remotely this . is the best news i've ever seen it's . time to play that's what martin said . with my 240 years i everything's looking . good now it's time to party so it's . gonna be fun. [music]. so if you look at the graph you can. still see it's doing weird fluctuation . stuff this time jake promotive is almost . convinced that there's still some sort. of boost leak so he's going to create . some sort of boost leak tester and . pressure test a system like 45 psi and . hopefully get it figured out so if we . will be back ripping this thing in no. time. [music]. alright guys so i guess that's just how . some things go sometimes and at least it . seems like the waste gates cooperating . now and it's just a boost liek the . fingers crossed. it'll get figured out soon i know this . was just kind of like a short kind of . random little update on the car but . we're on a cruise right now probably i'm . assuming based on when i upload this. video so i hope you guys enjoyed the . short little video and if you are bored . go watch some of our old videos we made . videos when we were on a cruise so you . could watch those videos if you want to . watch cruise videos oh yeah i dropped my . camera earlier today so it's not really . working that well anymore so hopefully . all of today's footage works and came . out nice but my guys bye guys and i will. see you in two days . [music]. when you say. thanks . me that. [music]. .
