WCGW when you power-shift a modified WRX with a stock transmission?

The amount of people in this fucking comment section that have never opened the hood of their own car is pathetic.

He knows he's pushing too much horsepower to the stock trans. He probably has a new one sitting in the garage.

Yes this video seems like a skit. Conveniently asking “how’s the trans holding up” and then power shifting…

Yep done the same.

Had a new built engine ready to go. Old engine was literally a boat anchor. It ran and worked fine but was common and thus very inexpensive. No one would pay me anything for it. I could only get scrap value.

They commonly blew up at ~450 HP, about 8-10 lbs of boost.

It was time for the new engine. "Hey let's see how long this thing lives at 15 psi"

Till about 4200 RPM on the first pull was the answer as it shot the rods out the side of the block. Party.

And tada, the scrap value engine was still worth only scrap value because they don't care there's a giant hole in the block.

On the new engine that was ~680 ft lbs of torque at the wheels at 4200 RPM. Yeah no wonder the little wimpy rods left the chat.

Sometimes it just doesn't matter and you can make a silly video out of it.

I don't know what any of this means and I wish I did. Car people are cool.

They planned to put a more powerful engine in their car, which was ready to go but not yet installed. The old engine wasn't worth much but still ran.

They commonly blew up at ~450 HP, about 8-10 lbs of boost.

The original engine was known to break if you added too much power via a turbo or supercharger.

It was time for the new engine. "Hey let's see how long this thing lives at 15 psi"

Before installing the new engine, they intentionally set the old one to run with more power than it could handle. A lot more. For funsies.

Till about 4200 RPM on the first pull was the answer as it shot the rods out the side of the block. Party.

The old engine lasted for a couple of seconds the first time it was pushed hard, before failing catastrophically. Now the new motor gets to go in.

And tada, the scrap value engine was still worth only scrap value because they don't care there's a giant hole in the block.

Old engine was going to be melted down anyway, so the ~$20 it was worth before didn't change.

On the new engine that was ~680 ft lbs of torque at the wheels at 4200 RPM. Yeah no wonder the little wimpy rods left the chat.

With the same setup, the new motor made ~50% more power than the known limit of the old one, i.e. not at all surprising that it blew up immediately.

Hope that helps.

What blew up - the new engine, or the transmission?

u/TheBeatGoesAnanas 4h ago

The old motor.

u/the_duck17 4h ago

Yeah but what happened afterwards and did he ever find true love?

u/thx_comcast 4h ago

Sadly no :(

Or two hobbyists knowing that they’ve pushed this particular project too far and are completely nonplussed when it fails the way that they expected.

That is not a dashcam,

u/bonicr 10h ago

Yeah, blowing up a transmission can literally kill you. Parts can and have flown through car cabins before, so no this is not a skit dude.

u/cuzitsthere 10h ago

Oh fuck off lmao

This is not a 1000+ hp drag car or competition diesel and passenger cars have steel tubs... Barring some freak accident, this is borderline impossible.

1

u/bonicr 7h ago

Oh, go fuck yourself, lmao

I’ve seen stock C5 and C6 Corvettes that have had parts make it into their cabin, stfu and quit lying to mislead people

u/cuzitsthere 7h ago

Sure ya have. Lotta dead folks with clutch bearing lodged in their ribs just outside the Chevy dealership, right?

Or... Oh... A piece or two was found in the passenger cabin and nobody got hurt because the steel belly pan shed enough velocity to make the pieces harmless?

Ouch, that'll hurt your fear mongering bullshit...

1

u/bonicr 7h ago

Oh yeah, because every single person who leaves a Chevy dealership floors it and power shifts after putting turbos on there at the service department… stfu again dude holy crap

Nobody got hurt in the couple occasions that I’ve seen either because they were wearing a race suit or because they got lucky.

I really hope you don’t believe me and that you have the means to put too much horsepower into a shitbox and powershift it to hell, because I sure as shit know you have the brains for that kind of activity. I humanity as a whole is lucky, then you’ll find out…

u/cuzitsthere 7h ago

Hoo boy, looks like you took a transmission to the brain there at the end. I've heard that's common...

u/bonicr 7h ago

Yeah dude you’re stroking out, seek help.

u/senorbarriga57 9h ago

Based in LA, a 2017 used with 88k miles is worth about 8 bands, seen cheaper modded wrx's.

u/These-Anxiety-5919 9h ago

WRXs are like BMWs and Porsches. If you can't afford a new one you definitely can't afford a used one.

2

u/Timely-Jelly-6414 8h ago

Comparing a car that brand new costs less than the average car price to a BMW or Porsche is certainly a take. They are dirt cheap to maintain and repair. It's an underpowered japanese 4cylinder engine.

1

u/These-Anxiety-5919 8h ago

It's an interference  Boxer that 20 something dudes with egos rag out every day on the way to work.

They're cheap to maintain if you maintain them.

u/forzaguy125 8h ago

I was doing a drift ride along once, near the end of the run there was a pop, a plume of smoke from under the hood, and no power. As it turns out one of the connecting rods wanted out of the block. The owner, didn’t seem too upset, I asked why, he responded “yeah I’ve got a built SR20 waiting to go in” meaning that he had a spare motor for his 240sx

Pictured here is said connecting rod

u/BlasterPhase 7h ago

He probably has a new one sitting in the garage.

or maybe he's just a dumbass, as is more common

Share your project car.

/u/Representative_Yau please share any hobby you have that you have accomplished something in.

I wrench my shit and that doesn’t stop this guy from being lame.

u/LifeIsOkayIGuess 6h ago

Blowing shit up is kinda part of the hobby. I'm pushing 450 wheel on a stock mercedes 7 speed just cause it works for now. When it starts having trouble I'll just start making plans to buy an upgraded one.

1

u/Hellament 9h ago

Yea, pretty common on a WRX to replace the TY75 trans with a more robust WRX/STI TY85 trans if you’re planning to really push HP/Torque with a tune.

1

u/RevolutionaryBad3722 8h ago

I feel like the keeping the gas pedal down while trying to jam into another gear is what did it. I’ve never heard of “power shifting” before this thread, but it seems like the fastest way to fuck up a car!

1

u/These-Anxiety-5919 8h ago

Clutch is a much cheaper point of failure than piston rods when you're doing the zoomies.

u/Vivian_Stringer_Bell 1h ago

Or the amount of you buying this video as not rage bait.

u/These-Anxiety-5919 44m ago

Things on social media being engagement bait is implied and not the epiphany you might think it is.

“Imagine having enough money”

u/These-Anxiety-5919 9h ago

It's an 8k car and a $900 part.

Do you have zero hobbies?

What's your weed budget?

2

u/supersimpsonman 8h ago

I have hobbies. I’ve spent about 8 thousand dollars on pc gaming. But that’s been over almost 15 years at this point.

u/These-Anxiety-5919 8h ago

I spent $8000 on pc components in 2025 alone. Gaming/Homelab isn't even in my top 3 most expensive hobbies.

u/OmNomOnSouls 7h ago

Then can you imagine, for a moment, that what the guy in this video is doing would seem idiotic to someone who *can't hurl around a thousand dollars like it's nothing?

0

u/These-Anxiety-5919 6h ago

What does "like it's nothing" even mean? I'm sure he works for his money like anyone else and with a tune/setup like he has going he planned for stock transmission failure. I was making 7.25 an hour when I was 19 and still put a turbo and fuel system on my car.

The amount of people in this fucking comment section that have never opened the hood of their own car is pathetic.

They could all pop the hoods and not know what they are looking at. You could tell them the ac compressor is the carburetor and they would go "Ah yes."
