1974 Rotary Swapped Corolla Hits The Dyno!

[Applause] well luckily Amazon had oil coolers ready to go yeah made it real easy got the same half price China One which is obviously identical just without a big fancy logo on it and uh this one should do the trick so I don't think it hurt the motor or anything I talked to Mike a little bit more after that whole incident and uh yeah next D got this one from Amazon and should do the trick for us yeah and it's a little bigger so yeah a little bigger I noed the oil temps were getting a little bit hot so I figured it could fit a little bit bigger one might as well and then I Al also ordered another one just to have a backup for sick week so never know but trying to cover all our bases for this week yep got her top back off with oil fired it up sounds good oil pressure is good so yep all away so we'll take it to the dino tomorrow see what it does [Music] [Music] big Dino day for the Cora yeah man we'll see what it makes we're probably going to shoot like 400 hopefully keep this reaction alive and get it to where it's drivable cuz right now it is really not easy on those ratchet straps back there yeah we might tear the car apart man hel together with a whole lot all right guys we got the Corolla on the dyo we are over here at Full Throttle Fab and repair like always got her strapped down and right now why is kind of going over the tune and we are on the phone with the Dorito boy himself he's at home shirtless right now helping us out over the phone there he is and uh bad boy I got [Laughter] tattoos but uh we're starting with the sidekicks base tune to kind of build off of and uh kind of go from there so made some changes going to try to work on the driveability first probably and then from there on do some power pulls and see what it does that's the plan and not blow it up and not blow it up that's key I mean to be fair man I I tune the sidekick on the street in front of Crystal so is that why it run so bad it a't it ain't blown up yet you going to sick week Mike yeah if it doesn't if my truck doesn't blow up tomorrow we're going to see you guys there nice perfect we'll see you [Music] [Music] there so wife has been doing a little driveability making sure that it is running good we're about to calibrate the dyno and then do some power pools and see what she [Music] [Applause] makes first shake down hit on the dyno it did 225 at 191 ft-lb of torque out of the Dorito box yep so I've been playing hell with it this morning just trying to get kind of the fuel map where we need it so it doesn't go lean all weird and uh got that kind of sorted and then I've been talking to Mike and the problem is with the full exhaust 3-in exhaust and the really tight exhaust housing we're running into a lot of back pressure issues so I'm not sure we're going to be able to make a whole lot more power right now because we're at 5 lb of boost but 8 lb of dry pressure so it's more than 1 to one which is really not ideal and that's why I'm also only revving it to about 7,000 RPM right now because anything above that it just wants to break up because of the extra back pressure um so what I'm going to try and do is overnight a larger exhaust housing for this Turbo from VSS racing so we can hopefully have that for a sick week and make more power but uh for right now we're just going to work on getting this thing cleaned up a little bit get the driveability a little more dialed in and then go from there but uh couple little issues we got to get figured out but it's starting to make some progress we might try and turn it up a little bit more see if it'll do some more power but uh definitely needs a bigger exhaust housing on that turbo for sure getting ready to go for pool number [Music] two that was a big old Fireball that one was 266 it it sounded or it felt better the Boost definitely picked up looks like you had a little breaking up going into the pool there yeah I don't know what's up with it it's just got this super finicky lean spot what you think about this W whatever it ain't me doing it I don't care cardo's up under here pulling our exhaust off cuz we have a little bit of a back pressure issue and we want to see if the exhaust is contrib want to see any of it I know why it's doing it but why I went to the bathroom will not take what I said for an answer so here we are you think that'd be enough light I don't know I Ain crawling my ass down there yeah that' probably be enough he's loud [Music] now [Music] 292 on that one Jesus did that fireball come up inside here all up in this holy ridiculous damn what happened here well I guess see how much boost that was in if the back pressure got any better that's more the question is the back pressure versus the Boost the Boost is we can always make more boost but you got to fight the back pressure first it revved out a lot further I'll tell you that we still dropped to 7 lbs at the end and web of boost we still got 12 lb of dry pressure it it made more boost it carried the Boost out further and didn't drop as bad but it still made the same back pressure so this turbine housing is just way too tight and uh that's where we're at with it that was AAR that some was all up in here I was about ready to grab a fire ex I know I was about ready to kill it I was like put the flame out all right guys we got the exhaust back on going for another pull [Music] here 300 we hit 300 nice not bad 8 lb yeah I made 8 lb out the top on that one like 11 lb down low um but you can see here in the log as we as we're increasing RPM our boost is tapering off and our back pressure is coming up so green line down here is back pressure red line is Boost and yeah that's not good how much the back pressure keeps climbing as the Boost continues to drop off y so definitely need a bigger exhaust housing on this thing yep I think that'll take care of a lot of our problems rotaries flow a lot of air yeah so tried to size it to have like a good responding Street setup but just need to go a little bigger yeah yeah a little bigger I think it' be pretty good help on this thing turned her up what 10 more per. try it one more time yeah we're going to give her a shot see what it does and uh probably be the last pull just it was just cool to put up a number but really I'm going to turn it back down so that it runs efficiently and you don't break that rear end yeah that's going to be the next thing that's going to let go for [Music] sure 332 we might be out of fuel I got a low fuel pressure light that time so 32 yeah not bad starting to pick up yeah we haven't put gas in it all day yeah we've been doing pull after pole with no gas so I think we uh finally just ran her a l low so hopefully she didn't get too lean there well we're calling it there 330 horsepower at 11 lb of boost yep is what it is yeah just making a little too much back pressure but right it's plenty of power for this rear end anyways so yeah yeah it's going to destroy this thing if we're done with it and uh later on in the future obviously we're going to swap it motor's capable of more power so that's all in the future but right now the key is to get it through sick week and I'm still unsure if it's going to do that so we need to focus on that right now and uh making more power is kind of the least of our worries so that's where we're going to leave it we'll call it a win though shot some sick Fireballs made 300 plus now he just got yep burnt some of his leg hairs just got to make sure the cooling Situation's good and figured out and should just about be ready to go yeah should be we'll know uh for sure here in about 2 three days yep it's coming up yep going to ride or it ain't it's driving way better now oh yeah not bucking and banging nearly as bad yeah it still definitely needs a little bit but it's nothing he's somewhat drivable now which is really [Music] nice oh started to break them loose a little bit yeah she started to SP this thing's going to be so sketchy bro but at least it's driving it's somewhat drivable it still needs a little bit of a pickup fix right as it's coming into boost but definitely a lot better than it [Applause] [Music] was
