You needed to make sure the high voltage battery was charged. You can force charge by holding down the brake and gas at the same time. Horsepower drops about 35hp when the pack is discharged.
@@therandomrobert1842 5 months late but you have to put the car in drive and push the pedal a bit so it doesn’t just engage the hv battery. Hope this helps if you still own the Prius and don’t already know how 😅
Some interesting comments on the video. 3 seemingly steady runs followed by a massive power drop, and people are saying it means the battery was probably depleted during the first runs. This should probably be taken into consideration when testing all kinds of electric vehicles.
I’ve found that almost any changes either get learned out or have an effect but it takes a couple hundred miles of driving for the car to adjust. Best performance mod so far has been the red bullet vvt-i valve and replacing or cleaning the vvt screen. Cold air intakes get learned out pretty quickly.
On hybrid cars, you can get them to run the engine only. This is what you should have done on the dyno. Remove the latching high voltage safety plug. This may not work on a Prius as I haven't tried it, but you guys should have. It may cause a CEL, but those are deletable.
Edit: There is a maintenance mode module that plugs into the OBD2 port that will just run the engine and the engine will not charge the batteries. Toyota mechanics that work on Prii should have access to this tool. Some of the higher end OBD2 readers should have this functionality too. So if Toyota mechanics and engineers have used this tool, why would it be unsafe? And how would running engine only on a hybrid on a dyno be more dangerous than running some other ICE on a dyno?
Was the drop in horsepower not related to the hv battery? I want to install a cold air intake purely for the sound but not at the expense of 5 horsepower would appreciate a response
Could I make more horse power on my Toyota Corolla hybrid? (122 hp) I already have cold air intake and about to do downpipe and straight pipe, but can I do something else?
Could've been cause by heat since the new intake doesn't have a box around it to insulate it from the hot parts of the engine. Not that that engine probably gets severely hot though...
@@mptperformance Well obviously not. I just applied the logic here (a bit) I'm not a mechanic nor having knowledge of whatsoever cars haha but by seeing videos around and how car respond is when it's stressed and so on. For eg. The new Lexus cross with over 450hp+ all they did to get 60hp+ was to add a better cooling to their battery sistem. Then there is the CT 1.8 200h vs Corolla/Auris ye? Literally same car, chasis, engine, everything. Just the interiors and the Lexus is heavier with over 100kg I belive and it manage to be faster with half second? How, why? Just becouse of the badge (lexus) lol? Nop! I know in Jetco cvt's, you need a better cooling oil for the cvt becouse it gets hot really fast, way faster than the Aisin ones (Toyota, Honda so on..) Tbh I just assume that to get more power would be this two major things to do on a hybrid without remap ofc lol. Have a bigger battery cooling and a better cvt oil!
@@mptperformance I'll see if I still have it 😁 also, Ive seen some pri freak out on a dyno, makes more HP in normal mode over PWR. but I think that was a fourth gen :D
LMAO! Happy AFD. If ur being serious, don't ya need to reset the stock ECU and drive it a while? At least, that's my experience with mild modding a stock K24

A Prius can not gain any power by installing other hardware, because: - the Prius engine isn't operated near its mechanical limit. - the throttle is opened around 63% max. - the system power (ICE+EV) is limited by the computer. - the torque is measured in the transmission case. All torque/power gain or loss of the ICE is compensated by the EV. Your power drop in the last run was just because the high voltage akku was down. If not you had comparable results to before. Any power gain of a Toyota/Lexus Hybrid system needs to be achieved and getting unlimited in the software, not vice versa!
@@Sam-vw2be You need to find one who is able to take the 165/170/180 km/h limit out of the hybrid system. But I don't have the slightest clue how and I don't know anyone in person who's able to crack that code. 🤪🤷♂️
How does this even make sense to test? The engine is just a generator. More generator power means nothing for wheel horsepower that’s based on the battery…. More generator speed would maybe make a difference but you don’t change that.
@@miklee9584 I don’t want to say you’re wrong, but as a Prius owner and rebuilder you’re completely wrong. There is no transmission. There’s simply a differential and motor generators. Absolutely no correlation between speed and rpm.
@@miklee9584 I lied, newer Prius’s do have a CVT. But he’s testing a second gen, which just has what Toyota calls a “transaxle” but is operating at a single gear ratio. Any slippage is done electromagnetically.
No air in take is fully utilized unless it's tuned for the car to understand pretty sure no one is tuning a Prius TOYOTA No's exactly what there doing with these cars in my opinion only way your going to get any gains with a Prius is buying light weight rims and even that would be minimal benefits you guys do tuning you new you were wasting your time before you even started
@@mptperformance Frankenstein motorworks does it with the 2AR-FXE engine, it should work on the ZR as well. Replacing the exhaust cam with a stock intake cam helps as well. The dude gets 280 out of a full oem parts engine.

I think you're right
When the battery is low it really struggles to climb a steep hill. Battery charge makes a big difference.
I’ve found that almost any changes either get learned out or have an effect but it takes a couple hundred miles of driving for the car to adjust. Best performance mod so far has been the red bullet vvt-i valve and replacing or cleaning the vvt screen.

Thank you for that.
Horse power decrease is because the battery was depleted. If battery was charged it be higher.
Especially if the car was just idle in between runs.
There's a significant difference for sure when the battery is low vs when it is full after regen.
On hybrid cars, you can get them to run the engine only. This is what you should have done on the dyno. Remove the latching high voltage safety plug. This may not work on a Prius as I haven't tried it, but you guys should have. It may cause a CEL, but those are deletable.
Anyone else reading this, keep your damn dirty hands off the high voltage electronics .
Not doing that.

Going to agree with you there
You can improve the electric power by adding a WAY better cooling sistem to the batteries belive me! The Aisin cvt can handle ton of power
Have you done this before?

Massive hp! Click bait?
You might be on to something there 🧐
A question no one asked
Have a feeling you might be right. Since its been a while, just going to reiterate this vid was uploaded Apr 1st.
Horsepower os dropping because the small battery has lost its charge.
Could be the case.
