@@v6pulsar studs got lube, just didn't film applying lube to 10 studs.

Came here to comment this, removing the squirters while doing an endurance build is a real mistake.

⁠hillclimb isn't endurance. There's alost of really short hillclimb events that feel more like autocross up a hill.

@@mastercricket7626 Full disclaimer, motor's built to handle around ~900whp, but I only plan to run it around the 600whp mark(or wherever my turbo maxes out at). I'm already gonna have enough traction issues at that power level...

@wingman703 Right on , epic build regardless broski 👌🏽, hope it's everything you want it to be, bro .. 🤘🏽🤙🏽✌🏽

@@ThePeakMotorsports the prompts I had to use to get that footage... You wouldn't even believe.

@@234Nick Machine shop filed for me, I double checked them but didn't film it.

@@GasPedalGarage "fuck I hope this works"

@@colel9450 nope, all bolt on stuff that came with the shifter kit.

Link to the pertinent build thread page in description.

@@Omeshan motor definitely went boom from too much boost, but not from an overboost. It hit the targets I requested, those targets were just to aggressive for the 3 season deep junkyard stock engine to handle. Runaway boost on a gas engine sounds absurd, any halfway decent ECU will allow you to set a maximum boost level, and above that it kills fuel and spark. No fuel+spark, no combustion, no turbo spool, no boost.

@@wingman703 Ah well, heres to soon seeing all your targets met! I agree that boost safety in your ECU should be everything and all you need. Wondering if maybe they just put a big number as a target and after motor went boom, then the box of excuses came out? Anyway, we will never know, but we appreciate you. Seeing the ups and downs makes the story great. Will be awaiting the next high!

@@williamchandler6151 Too much boost to quickly combined with overly aggressive TC methods.

@@DBatty You can thank Bronson for that!

And the end, definitely a bummer, hope you get everything dialed back in

@@CadeMidgett BP would have blown up last episode when I started it the first time 😂

@@Doomburger7 Built motor was going to happen eventually anyway... Just wasn't planning on so soon 😆

@@jayjohnson600 There's not currently a diffuser on the car. The was one last year, but I smashed it up when I tapped the wall at Road Atlanta and haven't made a new one yet.

@@sethmonteleone8178 I had to Google translate that, not part of the normal MK60 curriculum 😆

@@CameronHall-wq9tk No, but roughly the same size I think. There's a dozen generic 26" wide radiators on Summit, the tricky part is getting one with the right inlet/outlet sizes and locations.

Same here from qld 😂

@@kenthill5252 hahahaha

@@Omeshan interesting to see I have so many Aussie viewers!

@@wingman703 I am actually form South Africa. I was in Aus for work, and will do my build there once I move, but I just landed from my 24 hours of flying back home in South Africa. Now i get to go fiddling with the cars i have here after a few months of being away!

@@sethmonteleone8178 In the edit I was like "Hmm... I didn't fully think though that shot. Fuck it, she stays"

@@sethmonteleone8178 Hey man, it's hot down here. Gotta keep the little piggies cool

@@Doomburger7 I have not heard of this, what's the benefit of running the system in reverse? Any sources or solid information as to?

@@wingman703 So, Reverse Flow Cooling is something that Smokey Yunick worked on and that Pontiac used in 1955-1960. GM also used it in the 2nd gen LT1/4 and I've seen it used in some pretty unsuspecting engines more recently (Mercedes, I believe). The mechanism seems to be that the cylinder head conducts most of the combustion chamber and exhaust heat and exchanges that heat with the incoming intake charge. In addition, the exhaust valves and cylinder head are two primary sources of hotspots in the combustion chamber, so giving the head priority cooling alleviates these effects and raises the knock threshold of the engine, enabling higher compression or boost and/or timing advance. I still don't know the effect that reversing the coolant flow has on the cylinder walls, but that seems to be less significant for performance and the few folks I've seen online who've ventured use it have reported that it works.

@@wingman703 YT seems to be deleting my comments with the links in for some reason, so I'll throw them in separately, but lmk if they don't come through.

@@Doomburger7 Links didn't work, but you've given me enough terms to research and look into. Thanks!

@@Omeshan Me from the future here. This cooling setup kicked ass. I struggled to get it to operating temps even in 90° ambient temps untill I halved my already small radiator inlet. The EWP's insane flow definitely helped, but the extra large triple pass radiator itself does serious work.

@@wingman703 Is it you from the future, or the vid is you front the past? Hmm NVM future you is cooler! So you couldnt get up to operating temps even with PWM at lowest so had to put more backpressure on pump to reduce flow? Would you have done anything differently? Like smaller Rad or smaller pump, or do you need the capacity when at full tilt? Space is a premium, so just asking. Also, do the NA headlights take up space and get in the way? They cool as hell... but space!

@@Omeshan Haha video me is past me for sure. Basically to get it to operating temp I leave the pump completely off until ~140°F, then run it at minimum duty until 190°, and start ramping up in flow rate from there. Trying to run it at minimum duty from 80° or lower ment warmup took 30-45min at idle. When moving and with some load in it, warm up is much quicker. Getting it warm in the winter(40°F and below temps) is definitely going to be a struggle, but that's future me problems! Definitely wouldn't reduce radiator size. Having the extra cooling capacity is going to allow me to upsize my intercooler, which you might notice is very much on the small side. I'd much, much rather have too much cooling capacity and need to downsize/block off inlets then not have enough and have overheating issues again. Popup headlights could probably be made to fit, but that's just weight and aero drag!

@@wingman703 I wish i could show you how much i appreciate your detail in replies. One day if we find ourselves in the same place in the world, drinks are on me. Your R&D is definitely worth it! My build is aimed at somewhat time attack but also street legal. If i land up building it in Australia, its harder - I need to then use an NA because its old enough to do a subframe swap (Aus rules are a headache), but i would like to use the NB... but i may try something weird with front end swaps... Problem for later me to look at space and rules and stuff.

@@Omeshan Just happy to bring everyone along for the highs(and lows) of building a fast Miata.
