guys guys guys calm down...

its a corolla fielder 2WD - came with a 2ZZ in japan and many were imported to NZ. I am not sure if NZ even got the hatch 2ZZ powered corolla.

Secondly, Dyno's are a tuning tool. whilst they can be accurate, they can also be manipulated quite easily so dont believe everything you read. i've never seen an accurate torque figure on any dyno, so dont get your hopes up this car doesnt have 1200nm of torque. the only thing a dyno could be useful for is if you did a baseline run, and then a run with the mods attached. Work out the increase in power/torque as a percentage increase. figures dont mean ****.

Anyways, its very nice look rolla mate i do like the wagons as well, very stylish!

who told you that... dynos are a tuning tool but are not as inaccurate as every 1 say they are... they do give fairly accurate torque readings so dnt talk from your a-ss

Seems like you're the one talking from your a-ss.

The torque figure is the least accurate representation of engine power due to driveline multiplication etc.

Do you seriously believe the engine has 1200Nm?

no i dnt believe it has 1200 nm in fourth gear on the dyno... do you agree with me that fourth gear is a true reading of the engines power to the wheels as it is a 1-1 ratio and hence y dyno runs are done in 4th gear as all the lower gears 1-2-3 have torque multiplication as the output gear is bigger than the input gear ...so if the torque wasnt measured in 4th gear the reading would not be correct like this example of 1200nm

and of course dyno's are not completely correct everybody knows that.. there are many variables for example temperatures tyre pressures and oils are just some of them.

Using the power formula rearanged to solve for torque, and using the power curve given above, yields torque in the region of 190-240Nm, give or take.

Hopefully this isn't going to be another dyno debate. There have been plenty in the past and everyones comments rest in them.

I think you guys that cant read dyno sheets need to listen and learn for once, instead of mouthing off about something you havnt got a clue about! It gets real boring listening to all the dribble!

Fisrt of all, the torque figure you see on the sheet is torque measured @ the wheels! hense why it looks unbelievable.. To get the accurate torque figure of the engine, you take the 1281.9 figure and divide it by the ratio which was 5.300.

1281.9 divided by 5.300 = 241.86Nm from the engine!!!!!

Hey mate, do even have a clue at what your looking at on a dyno sheet!!??? Cause I seriously doubt it!! Think about it man..the figures shown on a dyno sheet are from where?? The wheels! NOT the engine... so of course the engine doesnt put out 1281.9Nm of torque! As I said in other replies, that figure is divided by the ratio stated, which is 5.300.. you then get an accurate engine torque figure of 241.86Nm OK!

I was pointing out that the graph does not illustrate torque at the engine due to driveline multiplication, which a lot of members on here dont know...

But your repetitive, almost identical replies have also illustrated that

Hahaha. Sleeper why is it that nearly every time you post it always ends in an argument. Some people here know a lot more than you, so dont be so quick to attack.

Also rollamods i am surprise with the politeness of your reply, nice work :)

this thread delivers :D

hey Dylan, your pretty clever... I was wondering if you would be able to inform me what the ratio one should divide the torque reading by to get an accurate torque reading at the engine?

I couldnt quite work it out from this topic.

      Hey guys we have recently purchased a 2012 200 series (cut down dual cab - extended) 240km on the clock It lacks power when accelerating and the gear changes are delayed when you put the foot down. blows very little soot when accelerating Nil lights on the dash. Injectors seem to be reading ok. Only fault code that popped up was C1201 Any input is much appreciated.

      Upgrade from 2012 to 2023

      I have recently bought a 2012 Prado and was wondering if i could buy a 2023 strat write off prado and upgrade both interior and exterior so all the functions from the 2023 works regardless of the newer features and buttons. I'm planning to upgrade not just the exterior, I'm also planning to upgrade the interior dash and stuff as well.

      Towbars

      I went to my local Toyota Dealer for a nudge bar and tow bar for my 2017 AWD RAV4 and was told by their part's department was told "parts no longer made." Looking at aftermarket (ECB, Haymen Reese and ARB) but hesitant because sellers can't give 100% guarantee that parts will fit GLX facelift model.

      Concerns about Fuel Consumption in Kluger Hybrid

      I have the same issue with my 22 new Hybird Kluger. I also found my (grande) new Kluger has missed 220V power point and camera view on central mirror comparing with same car in US. This clearly are the short cuts to Australia Toyota customers which is unacceptable.

      ASV50 Camry Head Unit Options

      I have a 2014 Atara SL with the JBL Navigation head unit, it's getting a bit long in the tooth and I'd like to add Android Auto so I'm curious about what other owners have done. I don't want to lose the reverse camera and the dynamic guidelines, there are also some other car functions as part of it that would be good to keep. I have seen plug in modules that wire in that add the functionality to the existing unit so it's possible to keep it and switch between stock and android but I haven't seen a specific one for this model JBL unit. Has anyone had success with a later model Toyota unit bolting in?

      2007 Corolla Sedan rear seatbelt question

      there are online catalogues available that you can type your vin number in and it will show your car, then you can find the correct part number. it is the only way to go when looking for uniquie or uncommon parts. https://partsouq.com/en/catalog/genuine/vehicle?c=Toyota&ssd=%24*KwEWIjMeQU9MbFFuQ2JFQ05aen1jEh0QEQMFBkBlWQFNUQAaXyUmagcOAU1WABpfMidwEBZ5YWYREEpDXxQTEhYGCQBDHlFVBhQXGxcREgJRUQJHBxgBfn9nEU9APQliamV1Y2wCUVEJTUEAGRxYAAAAAL-x3O4%24&vid=0&q=AHT54ZEC307000605 https://www.amayama.com/en/catalogs/toyota/corolla-runx/1-hatchback-right-e120-2001-3066/body-and-interior-3/mudguard-spoiler-298

      Wheel size

      Hi everyone, I’ve just bought a nice clean 99 Corolla. I want to put some nice wheels in it, but am unsure as to what size will fit?

      1zz-fe engine rebuild

      Hello all, Working on my 2002 corolla. It needs a engine rebuild due to burning oil out the back. It has over 400,000 km on it and I havent looked after it. Everything is still original on the motor. The only thing that I have replaced, was the brushes on the alternator. They were completely worn out. I am pulling the motor/gearbox out of the car. Wont know the condition of the block or head until I strip it down. I know the design of the piston where changed in the 2003+ models for more oil holes, which stopped the buring of oil. 1. Was there any other changes made ? 2. Does anyone know of where I can get a engine rebuild kit for 1zz-fe motor in australia ? 3. I have only found one place that I can get a new short motor built but that is in the USA and they do ship to australia but was hoping to find something in australia Thanks for help. Dragon
