How to Break-In a Built Engine PROPERLY

[DumbTheories]

Interesting to see you guys cut the original break in period in half! Assuming the research had everything to do with that. Great video.

I broke in my stage 2.5 to 1, 800 miles this time just because. I also just learned that we have looser tolerances for pistons for higher power so I can hear the piston slap on warm up so that’s normal don’t be scared if you hear it. My STI is on 40 lbs of boost and I finally finished tuning.

Great video :) Looking forward to more info on the built FA24 :)

I found it very helpful as I’m nearing an engine swap on my 2016 wrx. With a 142, 000 miles it’s almost that time after I had a cam gear failure
With the motor removed to do the repair might as well swap it instead of paying for 2 engine removals

Perfect timing im mid engine build due in about next year of april, really helpful

After the 50 miles are you OK to get into a little bit of boost? Maybe 5-7 psi?

What do you do when it's a race car? I usually install the motor and send it to the dyno.

If you follow these steps... how did you fill the cooling system and engine passages with coolant?

Looking foward to do this on the new to me 08 sti

Hey guys does this process apply to brand new cars from the factory too? I'm gonna be taking delivery of a 2024 BRZ soon and I want to treat it right. 🙏

[leekouvlogzs]

any updates on this built FA24DIT motor with dyno pulls

[benmccann]

Any plans for an FA24 brz/gr86 built engine?

[SK]

Would this build fit into a GR86 running it NA or with an aftermarket super or turbo charger?

I can either buy a stock r35 gtr here in my country or a 950hp shortblock build and its hard to choose

I have Millers break in oil, But for the first startup I wanna use a mineral oil with ZDDP additive as I will be flushing it out after idling for 5-10 mins. Can I use "MOTUL 3000 4T Plus 10w-40HC-TECH Mineral Engine Oil" for the first 10 mins?

[WyFoster]

I've got an engines that run on M5. They get idled up to temp and then start doing full throttle pulls on the dyno.

Can we have a full overview of all the aesthetic mods on the car 🙏🏼

[krazyfil]

Is there a link to the break-in manual for race car setups?

[IHadToMakeThisAccount]

Curious, im build race engines in a different non automotive industry, we always recommend to change spark plus fairly quickly do to metal contamination from break in, do you guys not encounter that issue?
