    What was wrong with exhaust that caused the dip?

      If i had to guess, since changing a part of the exhaust system fixed the problem it mightve been the timing of the exhaust pressure waves were in sort of a, “wrong place at the wrong time” caused by what looks to be a sort of resonator since it was removed and then the dip in power went away.
      An exhaust system built to make power uses the exhaust pressure waves, produced by the engine, to scavenge exhaust gases out of the cylinder and pull intake air into the cylinder.
      Even if toyota made a cast iron log exhaust header for this engine, I dont think it could produce such a drastic dip in power at a certain engine speed like this.
      I think the exhaust pressure waves were perfectly timed to actually cause reverse flow and push SOME (not all) air backwards through the intake causing the intake air speed to slow down a lot. Hence the massive dip in power at a certain engine speed and then a quick recovery.
      I am no exhaust pro, this is my guess.

      Yes kinda as above, These headers run a choke point and cone setup. Along with the runners being the correct diameter. Its a part of the reason how it (and my engine setups) manages to hold onto the low end and start making more power through the middle with big cams. most are a dog till 6k with cams this big. but is a double edge sword and can cause some weird stuff if not terminated correctly. This is probably the worst ive seen, I dont know the specific science behind it. Likey some "bad" pressure waves from the exhaust and intake were lining up at the same time, causing some massive reversion at that point in the rpm range. This one is still bit wiggly below 4000rpm. but it wont really ever see that for its intended use. Also its not a thing at low throttle openings .

  • @garage79r
    @garage79r Місяць тому +8

    My initial impression was the exhaust was too big allowing reversion causing the power dip until there was enough flow to overcome it. The fact that cam timing just moved when it happened kinda proves that point. Then modding the exhaust changed it. So likely its just too big and too big too close to the motor

    • @hiperformance71
      @hiperformance71 Місяць тому

      Cam timing will shift up or down all the curve, this is used in those cases where you have a large dip in the range of utilization of the car in the race, so, you start to tweek with cams to shift that dips as low as possible, this solves in part the problem and gain usually in more torque and a fatter power curve maybe sacrificing a couple of hp on top, but every engine is different, and you need tools like dyno and tuneable ECUs, now, that's my work, tune racing 4 bangers on our dyno here in Italy, but mostly peugeots and fiats, here, toyotas are rare.

    • @Garage4age
      @Garage4age  Місяць тому +5

      as above, when running big cams with overlap, the engine becomes very sensitive to exhaust and intake changes. its no too hard to get the engine to work over a small rpm range. making it work over a big rpm range starts to get more tricky. this engine is actually doing pretty good it starts making more power than the factory engine from 4500rpm and goes all the way to 8800, (limited by the bottom end) and makes the same power at 5500 as the stock engine makes peak at 6600. ive have plenty other 4ages come through (not with my setup) and others dyno graphs when running similar size cams that dont do much till at least 5500rpm. below that being a massive hole. not many people share and show the whole rpm range. just peak numbers

      Yeah the video is a good example of on paper these parts will work. but in reality need to play with stuff and make physical changes to get the most out of na engines. Its not the cams or head's fault. things just get sensitive to pipe tuning, both intake and exhaust when running big cams with overlap. Cant really compare it to something like a K series honda or the likes, with cam lift and variable cam timing, which is a cheat code to make things run nice under 5000rpm. This is like vtec is stuck on and cam timing is stuck at full advance. which means cant tune around the sins of a bad intake and exhaust with a push of a few buttons

    @killsalot78 Місяць тому +1

    interesting there are still some dips in the curve yet it still has massive gains. I wonder what that comes from/how thats even possible. straight up like this engine has a VVTI issue or something but this seems like a fixed setup. It sucks too because 2800rpm and 4k are right in the ranges that you don't want a drop in power. Are you sure the ECU is tuned right? not dumping too much gas at those points in the map are ye? I would be extremely interested to see this setup tested with a carburetor.

    • @Garage4age
      @Garage4age  Місяць тому

      Things get sensitive with cam overlap. can throw what ever setup you like at a stock/ mild cam setup. The dips arent really an issue in the low rpm, esp in this car getting used for its intended use. also It doesn't do it at low throttle openings where you would be driving around normally. The ecu is tuned correct yes. in some of the testing runs it wasn't down there (3k and below) as its a lot of mucking around for part of the rpm range not too worried about until the final tune up. those bumps are the hardest part to dial in, as the fuel map needs to change as much as the dyno graph suggests over a very small rpm range, you have to start moving the rpm points around in the fuel map. turbo stuff making 3x the power is actually a walk in the park to tune, compared to aggressively cammed na stuff.

    Hello, since you know a thing or two and after looking at this exhaust. Could you "confirm" the case of needing smaller exhaust diameter at the back of exhaust ? i have read it here and there that exhaust gas heat drops -> velocity goes down with it and to counter this you would switch to smaller diameter pipe to get that flow back up, but is this a true case ? somehow i could see the jump from going bigger to smaller also cutting out velocity and causing turbulence in the flow. Btw love your videos, love the way you make them compact and also give us something to think about :)

      There is a lot of wizardry going on in the first part of the exhaust, up to the end of first muffler. after that you could cut the exhaust off. run a 6" pipe or get away with dropping to a smaller size as seen here, and would do basically zero. mess with the stuff before that and things start to happen.

    Hey man, loving the channel! Awesome video as usual!
    I was curious if you would be open to trying an experiment with the exhaust manifold?
    I have been looking into how different exhaust sounds are made, and one in particular caught my attention - being the classic F1 sound.
    Essentially, the way it works is there are 'steps' in an equal length exhaust header, which causes the exhaust pulses to split in two on their way through the 'step' right through the collector in which they are multiplied even further.
    I have just watched a brilliant video explaining how the sound is made which is best explained in this video by Maisteer (linked below) if youre interested in a better explanation, and also that he has this done on a 4cyl engine which sounds AWESOME!
    I would love to see you give this a try on the 4AGE hey, it could be something absolutely next level!

      The reason Maester's 4 cyl exhaust sounds like that, is because its a tiny bike engine with a super short stroke (Like an F1 car) doing 15,000rpm (like an F1 car)
      He needs to prove the concept by getting the sub 8000rpm V12 sounding like that.

    Does it really need more that 2" exhaust? At least about a meter or so after the header to keep the flow velocity high.

      yes, lets the headers and collector section do its thing. It doesn't go directly to 3" at the collector merge.

    He went to the right guy, with 174hp he's got more power than a BT, and it sounds good and "feels" reliable! For drifting that's what you need.
    This reminds me of the white NZ 20v 2dr featured on Driven a few years back, but I guess there's no affiliation.
    For just mildly beefing up an AE92 at a budget, would you recommend Toda underbucket or would "measure onc" with the Yaris stuff also work?

      exhaust and intake doing stuff with the cam overlap. can see it moves around with the intake change and cam timing. my dyno makes it look worse than it is, but its a thing. more time changing intake and exhaust setup can fix it, but need to be careful not to screw up the top end power while doing so.

    ahh u shaved the head so compression went up plus -even though gasket thickness to compensate, what comp was from stock head to new head? id be happy with 48 hp and if u managed to dropped some weight out of the car it be like a dream come true

    • @Garage4age
      @Garage4age  Місяць тому +2

      The new head has had a bit of a skim to compensate for the material taken out of the chambers, from de-shielding the valves etc. I didn't measure the actual compression ratio, but assuming the stock head hadn't been skimmed before. It would have been around 11:1 compression ratio with the .5mm gasket. with the new head and .8mm gasket, would be around the same if not a little less.

      @Garage4age have u heard of the qauliport valve arrangement basically its a 1 big intake valve to force a swirl in the induction and compression stroke. Im pretty sure it was the 20v overall idea with 5v i feel like your a guy that could do it easily with your skills

      @@Sat_tyre Head should be good for plenty more. I dont think oversized valves will do much for it, if you were to keep everything else the same. The cams sound pretty big, but they are stock shim cams. cams designed for the bigger area of a shim under or shimless bucket, are far more aggressive for same duration. which is what i would go for after sorting the bottom end and intake. I used these cams as had them hanging about and were the right price. obviously make some not bad numbers too. Its really not a big budget build
