K24 Testing & tuning VTC, VTEC - Dyno tested k24 pt1 

More Honda Please especially the k24.

More Honda's 100%, might even help grow your audience a little bit

Would be great to see comparisons with your motors, Love to see the underappreciated H/F series stuff get some analysis, despite it's underwhelming rod to stroke ratio

I accept any internal combustion. Rotary to V8, Diesel to NitroMethane. I have my favorite brands, but I don't let that get in the way to watch something new and different.

More honda, would love to see a B16B. if you can take out so much from a 4A-GE, i would like to know what you can do with an engine that already has over 110hp/l

^^^^ Would love to know optimal setups for my own car!

Yup, there is no denying that the K-series top end flows exceptionally well from the OEM casting, but it responds even better to port and flow work so I'd bet there would be even more gains to be had with some work on a flowbench especially. The intake would definitely benefit from being located better, or with a proper heat shield and seal to the hood, and I'm also willing to bet some adjustable cam gears would make better use of the cams/ powerband right off the start. Without the gears you can't degree the cams which is leaving some on the table. Thanks for sharing this man. 👍

Hoping to do headers and exhaust. struggling to find the tube size for headers at a decent price atm. My usual supplier doesn't have it. would be keen to do custom inlet as well but not much room in this chassis for what i want to try.

K series, that is next JZ engine 😅

plm makes affordable headers for the k20-k24@@Garage4age

He didn't gain 10hp as such, just stopped leaving it on the table

ok kia on the way, ha!

Can't have your intake air getting cold!

@@Garage4age you could do an intake test that pulls air directly from the exhaust!

yup - its a hot air intake from hell really.... when the bonnet is closed you'll hit like 60c air intake temps for real in traffic - down to 30 on the motorway cruising - and up to 40 if you thrash it - it neeeeeeeeds a cold air intake - but that particular intake makes vtec sound stupid loud in the cabin so maybe thats why they did it? also if its the factory air temp sensor, that will heatsoak and lie about the intake air temps as well after it gets too warm - easy to replace with a sensor with the same curve tho :)

@@cbdrift Tbh i forgot to check if the iat has any trims on it. has a aem ecu. first time ive tuned one, so was finding my way around the software as well as filming and tuning.

well, there isnt really any room normally where to put filter in a colder location without moving the battery, ep3 has quite large hole and high up in the wheel well, thats where most of "coldish" air is coming to filter, also mine has a metal shielding plate between the filter and headers, but yes its not ideal, there are of course bottom mounted filters, just dont hit deep puddles

Great point.

I tested both on my car (Kmod Performance Stage 3 K24 E85). 4-1 headers (ASP) outperfom 4-2-1 everywhere. Just by the noise we can tell it flows better.

​@@Acercatemamiis damn right. Just pulled off a Ktuned 4-2-1 in favour of ASP 4-1, it gained everywhere on the 4-2-1. It picked up 18kw 7500-8600. Stock block K24a, 4P 156 head, DC3.2.

Oh no you didn't.. A toyota guy giving a toyota guy money on a honda video. what has the world come to

@Garage 4age If it ever gets to the point where im using a megasquirt I give you permission to shoot me.

Yeah it was meant to have the 50, but pulled it apart and confirmed it doesn't. also looks to be a tooth out (retarded)

Yo turbine what u doing over here

@@pr0n5tar aye !

Soon consult u on some tunerstudio shizz

No make me diss yuh

ecu doesn't have any knock protection. or have any knock issues. it does have iat sensor which should be used to trim fuel / Ignition. rather than leaving it rich all the time, will just get even richer as air gets hotter. the cam timing is another whole story. will cover it in next vid. All i can say, is the guy who had the work done didn't get what he paid for.

It looks to have the 50 deg rbc vtc pulley. I assume the guys that put it together have limited the pulley travel. will look into it, as it definitely wants more advance. long as there is piston to valve clearance available. as for other cars, its just what ends up here and i have time to video. this one is a friends car. but would be pretty interested to do some 2zz stuff

@@Garage4age ah i see well keep your good work i like it if by any chance you end up finding a car with a 2zz it would be nice if not than maybe i could contact you on email or something and maybe can work something with distance tuning 🤷‍♂️

Has rbc cast into it, so assuming that what it is. I would like to try a whole new inlet of my own design. but not much room in this chassis to do it. Yeah the exhaust is way too small.

how about a 3y? haha. I have been tempted to do something like that, to show the principals work on any engine. but likely wouldn't get any views. plus the lack of any larger camshafts and the likes available

Hey, it has an aem ecu. so more basic approach than how the factory ecu does it, i guess you could say. everything was wack on the cam timing side of things mechanically, will redo the cam timing in the next one

Most cases, isn't really any more power to be had going leaner. Was more to see what power would make as is, so had a solid baseline to work with. as planning on doing some changes. rest of the tune still needs work also, but no point sorting that out till have made said changes

This one is pretty rattly. probably could go some adjustment. doubt will do anything measurable though

@@Garage4age I know it won't do much, I just want to see hard evidence it won't. Plenty of people think it does, I just want to see the myth busted once and for all.

@@Garage4age oh holy shite - i buggered up my valve lash one time and made it too tight in my ep3 k20a - i really didnt want to fix it - gained a whole pile of seat of pants power out of the mistake - but was convinced by those who know more that it was bad due to cam ramps and valve closing shock loads n stuff - honestly felt like it had like 40hp more everywhere - set it back to factory - but now i want cams lol - it did a TONNE more to the car for me with my ep3

maxed out though the whole rev range. Im new to k series stuff, but no stranger to variable cam timing. so knew something wasn't right when that was the case. it was meant to have the 50deg pulley. but has the 25. which was a also a tooth out (retarded). In the process of skipping it 2 teeth forward. no idea if the 50 and 25 are indexed the same, if they are should give it a 15-40 deg range. will see how it goes like that and see what the owner wants to do
