[@opt123123]

Yeah man, k series engines are fascinating. There's a lot of myth and mystery surrounding the intake and exhaust manifold options, would be great to see you address them all like you have for the 4age

[@AutohousePerformanceProject]

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

[@caveone-365]

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.

[@f4rensabri]

Loving these dyno testing vids. They gave the rough idea of how much gain from each mod. To me the most important is how the power curve change after mods rather than absolute number so we can expect at what rpm range the power is made.

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.

Love your work mate, the customer will feel that everywhere on the road. Had a good laugh that the charge pipe runs from right where the cold air is, back to where the hot air is - awesome!

Can't have your intake air getting cold!

[@ricepony33]

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

[@cbdrift]

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 :)

[@Morgenstern591]

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

Nothing wrong with a bit of verity... couldn't stop looking at that intake though 😂

[@ChurchAutoTest]

Assuming you're still on the factory ECU, must be sure to do cam sweeps at each cam timing breakpoint. Tune each cam breakpoint fuel/timing map for optimum. Then select your cam angles for each rpm breakpoint. You'd be surprised how tuning each map fattens up the curve during cam angle transitions. Have fun. Sky's the limit if you've got the time and money (500+ whp on naturally aspirated, methanol 2.6 liter K-series race motors now).

[@Garage4age]

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

[@AmirPomen]

Awesome method of tuning and maximizing powerband.. 🤘 Moarrrrrr k series dyno please😊

[@Christdeliverme]

Probably the previous tuner backed off max cam so it's not mechanically maxed out and left some fuel in it so it wouldn't knock when it got heat soaked under load. The other thing is taking 2 degrees out having nothing changes is probably due to the ecu trying to reach it's max timing before knock

[@Garage4age]

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.

Good job! I think more videos like this would be great (despite the channel name). I suspect most people are interested in getting more out of an engine than specific brands - at least I am.

[@TBPony]

It would be cool to have more obscure engines on this Dyno just to see what can and can't be done to things, like say a Toyota 22RE or a 5AFE

[@Garage4age]

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

[@joe.cl7]

Inlet manifold is a genuine honda item RBC (CL7 Euro R) or RRC (FD2 Type R) - the later being better That mugen twinloop is probably restricting a lot of power. A 3" system should see a further gain

[@Garage4age]

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.

[@Garage4age]

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

[@weekendcardad1881]

The second I saw that FAT 11.7 AFR, I knew there was a ton of power to be had. Did you keep it at 12.5 AFR to be "safe", or do these NA K24's run better on the richer side? I vote for more K20/24 dyno videos. Ive seen all the other KZbin videos of people discussing what combo/parts to use, you could make a lot of content showing the differences on the dyno.

[@Garage4age]

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

[@rolandotillit2867]

Valve clearance! I've always wanted to see the difference between valve lash that's just a thou or 2 loose, vs tight on spec.

Next velocity stack vs throttle body size

[@fry.master]

should have left vtec engagement at 5000 ish, and just letf the timing alone imo.. keep the air filter clean, the actual engine bay will have more moving air and potentially take advantage of those couple of degrees, without any risk of knock like you had in your dyno testing cell/environment.

[@Garage4age]

Unsure if serious, but clearly a dip with vtec set that low. which is an exhaust side issue. will suck more hot air with bonnet shut and removing the air filer didnt do anything (tested off camera) was no knock, but also no point running more timing than it needs

[@fry.master]

@@Garage4age man I literally just typed out a very lengthy response and youtube automatically refreshed on my ass... lost it all. I was serious, and while I concede you have looked at the data concerning the vtec crossover engagement at "optimum" advance, you didn't realize that you need to tweak the timing during crossover on top of the crossover point itself. You can make that 5000rpm point there be the perfectly flat spot of torque you see at 6000, it just involves running less intake cam advance during the crossover, as well as properly adjusted fuel/timing trims (preventing unsettled combustion events from pulling power during the crossover itself) When it comes to your comments on air temps, I fully dispute them... you will have a lower density altitude in a moving car's engine bay outdoors than in your dyno cell with the hood up and a dinky fan blowing shop air at the block. During these times in real world applications, that extra 2 degrees of timing (so long as it actually doesn't trigger ANY knock tables at all, and was only removed for your opinionated "safety"), will help your customer reliably see/feel the gains they paid for when they drive the damn thing on the street in real life... *EDIT*:ADMITTEDLY: this involves keeping the air filter clean, engine bay clean, proper undertray/aero/underhood ventilation control.. basically the setup needs to be right, and this setup needs to be maintained more often when you take this razor edge approach to tuning. Not every customer is going to want to do that either, some guys go to protuners and not service their shit. In which case, if this was one of those guys, I agree pull that 2 degrees and if the power mostly stays, nice!

[@Garage4age]

@@fry.master yeah with the right intake setup i agree. but in this case the inlet of the filter pipe sits beside the exhaust manifold and behind the radiator. so would expect iat's to rise or at least be the same as on dyno. The cam timing was a tooth out on the vtc gear, hence the poor results and it being maxed out (advanced) everywhere to get best power. in the process of fixing this then will retune. it was basically running 10deg cam advance, since a tooth out is roughly 15deg. Pretty sure the vtec switch point can be lowered a lot with the right headers and exhaust and make a stack more midrange. its just the same as with a fixed big cam engine. most people take the hit in the lower part of the power band and blame the cams. but with the right setup doesnt have to be like that. vtec kinda cheating in a away. can get away with sins of bad setup by just turning vtec on later. and yep youtube will do that to ya, haha

[@fry.master]

@@Garage4age As far as I knew. a tooth out on vtc will most definitely cause serious issues on k series motors, and therefore I find it's impressive you were able to make any gains as is. Serious lemonade from a lemon, man. Im glad there ended up being a bit more to unpack there, subbed and hope you get all the algorithm love ofc.

[@Garage4age]

@@fry.master Yep, knew something wasn't right when it was gaining up top, adding what little advance it had left. should be pulling the timing back right up top. I'm new to k series, but have done a lot of cam timing stuff. Not expecting to gain much if any top end from fixing it, but should be a decent amount of midrange to pick up. basically i want to get everything working properly and the most power out of whats on the car, before i change anything else. Then i can see if the changes do anything.

stock vtc gear is limited to 25.

[@Silldro]

Which ignition timing was it as Base? My K20 seems to pickup power closer to 30deg compared to 25 deg. Not verified in dyno however. Seems possible with lower vtec crossover depending on exhaust manifold. Exhaust manifold should be tuned for peak power on vtec engines with 4-1 manifold, but 4-2-1 was the only i could fit in my small Renault

[@Garage4age]

from memory it was 28 or 29 degrees. so 26-27 somewhere now

[@Silldro]

@@Garage4age Thanks. Im running close to 30 so it might be a bit much. Not certain that K24 is the same as K20 due to longer stroke however. There is also some potential in optimizing cam timing on the lower engine speeds without vtech and how the cam timing at low engine speeds meets the cam timing at high speeds with vtech. The way to do it seems to be to set vtech activation to a higher than optimal engine speed and tune low engine speeds, then set vtech activation to a low engine speed and tune high engine speeds. Then find out the optimal switch point and start to phase the cam to the desired position a few hundred rpm before the vtech activation point. There is definitively some fine tuning in this. There are a lot of information that the Honda engine respond very well to large exhaust systems (3") and very large induction systems (3.5") but i havent been able to verify this on the K20 engine model. For a built K24 with cams i think there is some truth to that but not on a almost standard K20 och a non built K24

[@Garage4age]

@@Silldro Yeah ignition timing can vary a bit depending on engine and whats been done to it. pretty much everything likes a big exhaust. there is some wizardry needed after the collector merge to get the best out of them (any na engine), but after that bigger the better.. i run a 3" on my 4age

How are you tapering the vtc? The k series really loved to be tapered from high to lower at the top in. Good gains, definitely needs a 50° vtc that's manually locked to 45. Above 45 you start running into p2v clearance in the k24s

[@Garage4age]

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

​@@Garage4age Ok I see what you mean but why give us that number and not the one corrected from the RPM of the engine?

[@Garage4age]

@@krnt13 My dyno doesn't do that calculation. every load based dyno uses the numbers you see in my graphs in the background, along with roller/hub speed to calculate the power. then either rpm pickup or some manually entered numbers and the power numbers to give torque numbers. which is really torque at the engine minus the driveline loss. not wheel torque or engine torque. so is kinda a irrelevant scaling to keep the masses happy anyway. Anyway you can do the math from the rpm at top of graph if want to know those numbers. if we pick 5900 rpm which is 150kw = 243 nm . guess some driveline loss and would be 260-270nm at engine

I'm curious as to why you didn't check the VTC angles too? ... It's a time consuming process for sure, however there are great gains to be had in the mid-range and part throttle with setting the VTC correctly too. Most "professional" tunes I've seen so far appear to be "cookie cutter" type basemaps with minimal actual tuning.

[@Garage4age]

? its the first thing i did in the video, after the baseline runs. Was where i was expecting to make all the gains, after looking at the tune. Tune looked as you say, base map, make sure it runs ok (which it did) and send it out the door. progress stopped on the vtc tuning because ecu is reporting no more than 28deg vtc, so must be pinned or something. its not even to the point of needing to pull the advance back in the top end. it makes best power maxed out to 28deg everywhere
