Another video by my favourite lunatic. Cheers.
Good to see the old girl living through a dyno run!
That old beast definitely is a weapon! Might have made 50k with an oil change. Would like to see if DIY intercooler cooling works heard of guys using cooling fans and a windscreen washer jets to help the cooler with low speed off-road use, might be more of a thing for higher boost diesels never seen it dyno'ed.
I had just put fresh oil and filter on it, shes maxed out haha. The cooling on the white one is actually really good. its setup so the fans kick on often and pull air through both the radiator and intercooler. engine or iat dont get hot. So yeah probably not a good example to test the water sprayer on
@@Garage4age I'm givin her all she's got captain!
I dig the yellow HiLux
Thanks! Love your videos . Keep it up !
Thanks!
I wander if the old bonnet shut trick will work on the hilux
nice and legal
Teenage me thought removing the airbox top was all the power gains hahahaha
Solid test session!
The 2 day ago me was hoping for good things. or at least some noise haha
@@Garage4age good induction noise is all the rage in todays electric garbage pool of cars. ❤
ITB's for the win !
Sweet.
Any reason why the hilux dyno curve is so much smoother on the top end compared to the starlet?
Probably because of being a turbo instead of a high power NA.
Being a high power NA engine, it's way more sensitive to runner lenght, exhaust lenght, cams, timing, and probably a lot of other things i don't even think about. The turbo instead just makes power by increasing the amount of air in the intake
Stock cams and turbo. big cam n/a is super sensitive to whats happening in the intake and exhaust. effectively using the pressure waves the engine creates to fill the cylinder. so hard to get a textbook curve. If you are talking about the raw graph (most dyno's dont show this) being more jumpy on the starlet. the starlet is borderline overspeeding this dyno in 1:1 gear. the hilux i have to run up in 3rd gear. also it looks worse on a low power graph than a high power graph, as can be seen on the stock hilux
Where does that airbox intake tube go? Into the cabin?? or does a snorkel connect to the end
It pulls air out of the wiper tray. if go somewhere really muddy have taped the vents off in the wiper tray and pulled the fan out so pulls air out of the cab.
@@Garage4age I like it. Functional Sound Tube, and if you ever have a stroke and lose some brain cells, you can delete the BOV and pipe the sweet flutter of the turbo angels into the cabin maximally
Did boost remain the same with each air intake?
you can see it runs touch more boost on the runs it makes a little more, due to higher air density at the turbo entry. either from cooler air or higher pressure, or both. so more efficient power yep it would probably make the same power if adjusted the boost bang on for each run. not much of a drama in this case but in a more extreme case doing this would tax the turbo and engine more
remove the white car headlight and leave only the air filter remove the yellow car air filter and leave the whole assembly in place
I was going to but everything outside of the air filter ring is a rust hazard haha. thats why filter was still sitting in there.
If in the real world you drive with your hood down doesn’t that negate almost all the test runs you’ve done?
both the air boxes draw air from outside engine bay. just means the run with air filter only, would be even worse with bonnet shut.
The airflow is not nearly similar to a run on the road anyway, way to little airflow, so its not correct either just because the bonnet is shut. To properly test intake temps you either have the dyno in a wind tunnel or datalog during vehicle testing. :)
maybe you could have made the 50 if you could advance the ignition a bit ;)
What gearbox do you run with that motor? I just built a Suzuki sierra with a 4age 20v motor, 4 speed hilux gearbox(with 4age clutch) and Hilux axles and was wondering if the clutch is going to handle the weight/power
if its na still, stock clutch size will be fine. turbo/supercharged. can run the bigger ze clutch and flywheel.
Again super nice contain ! Did you plan on doing a vvti conversion on the hilux ?
thats the plan eventually
@@Garage4age that will be awsome
Mulțumesc
what diff are you running on that hilux?
stock with lockers. hi pinion and aftermarket cv's and shafts up front
What model hilux is this ?
N60 1984
Try air filter lid upside down on the N/A truck that should give good results with out having to spend any money.
Please put a Webber on the 3y' then dyno, then turbo?
Yes 😁 the hilux on dyno 🎉🎉🥳🥳
so good
👍
I've heard that boost doesn't care much about turbo/SC side intake dynamics as long as average airflow isn't less than what the engine needs. NA in my experience is quite sensitive to ram pipe and air box config. I have a similar airbox on my VP but it takes air around the headlight and the gap in the chassis rail and the rad. I had a restriction that was not seen on a engine that was internally stock but this one with mild cam and some head/comp mods hated the aftermarket airbox. The lid always got sucked under the top of the rad support but no restriction should have existed. So I ended up cutting the opening at the side quite a bit larger and the lid sucking down issue went away and the engine picked up a decent amount of power by the 0-100 time dropping a full 0.8 sec. I never re-tested on the dyno. On a guy's SC VS I know, he runs the stock airbox and makes 190kw no probs, but stock let alone aftermarket air box has issues on my car being NA.
I'm sure is a resonance thing that NA have where boost doesn't.
I had a similar result on my mate's ecotec race engine, it lost power with straight TB, but gained somewhere around 5kw with a 1.5m ram pipe, and about 8Nm iirc.
Yeah pre turbo / sc, is all about air density. cooler or higher pressure pre turbo means the turbo doesn't have to work as hard to make the same air density. so if the turbo or s/c isn't out of efficiency range it will usually mop up the sins of a restrictive intake. the pipe pre turbo doesnt really effect the intake tuning, since the turbo just chops it all up. na the intake tube being directly attached to the manifold, so becomes part of the tuning. The intake manifold itself on a turbo engine still has a big effect though. you may have seen the video of mine where i built and tested the intake manifold on the hilux It also has to do with the cams. bigger cams = more sensitive to intake and exhaust tuning. hence why turbo stuff usually runs smaller cams
@@Garage4age Pretty much what I have found as well.
rear tyres to 50psi might let it sneak past 50kw. Turbos don't care about fancy inlets as long as they can make boost it's all good. In my experience anyway.
With the fancy intake, it made a little more boost and a little more high end power than with the old intake or only the filter
Its all about pressure ratio's, thats why this engine makes the power it does on 14psi and stock cams. if had junk intake, intercooler, intake manifold, exhaust manifold and exhaust. it would probably still make the same power its making here. but would have to run more boost and make the turbo work harder to do so. engine would be more prone to knock also
@@Garage4age How about trying a tapered intake pipe on the front end of the turbo and stator vanes inside it to spin the incoming airflow in the opposite direction to the compressor. I did something like that on mine a few years back and got quicker spool up.
@@1magnit swirling in the other direction makes no sense AT ALL.
like put it in reverse if you want to drive forward. 🤦♀️
how on earth could somebody think this will improve things ?
@@casemodder89 Try telling that to those who design jet engines.
