Vid by vid the RPM scale is growing. Soon we will see the 11 000? Eagerly waiting. Thanks for the content!

[@Stale_Mahoney]

think the issue is at a certain rpm the piston speed gets so high it will struggle with keeping the oil film on the cylinder walls and run dry wearing the engine excessively, i know some engines are limited by piston speed and lubrication rather than the scare of throwing a rod/piston

[@Jamaniak]

I know it'd be alot of work but building and testing variable length ITB intake runners would be sick. A system like the 787B Mazda Le Mans car had.

[@SmoothCanoes]

Channel called FullBoost have done a video on something similar

[@LowMedow]

I've Been Thinking This For Awhile Now! 💪💪

[@s.a.f.r.a6403]

If a person could control the inlet length and cam timing together it wpuld be insane I know it has been done but rarely for performance more for emission control

[@kaophan1098]

Love the sound. Makes me wanna get back into old school toyotas again.

[@weekendcardad1881]

I'm nerding out at how you can see the 1st and 2nd harmonic waves of the ITBs move as you adjust the runner length. Very cool. But, tbh, I would have left it at 8* of timing for the 'meatier' mid-range torque. Unless you need that extra 10ish kW past 9,000rpms for drag racing, the 8* advance would have provided daily driving experience. Either way, I know this was all done for science for us engine geeks, so thank you!

[@Garage4age]

Yeah just seeing what kind of peak it makes before dropping back to a smaller cam combo. That's suited to a wider power band.

[@lee106rally]

[@ftovr2957]

Always find the 'wavelengths' of different lengths so interesting when it's changing intake lengths. Are these noticeable on the road at all, or not much when they're this close?

[@Garage4age]

In this case combine with the cam timing change, fixing that dip at 5300 would be very noticeable. the small gain up top not so much.

[@spicyF1]

lovely

[@ricardosingh3706]

Lovley video as usual. Just wanted to know how are you able to run or test so much of inlet advance with such large camshafts? Do you happen to have a fair amount of piston to valve clearance?

[@Garage4age]

Its basically maxed out, any further would = bad day

[@YABAYURENAULT4]

yo creía que ya a más de 9000rpm están flotando las valvulas no se si tienes resortes más fuertes y si no cambiarlos sería mucho mejor y la curva se mantendría sin problemas hasta las 9500rpm

[@panospapadimitriou3498]

i love the high end power and sophisticated headers like i want to make long tight and soft turns!!! too many mileage on mine so wont chase high end so will try 4.2.1 same patern !!! carbs already jeted rich so might try some work on head but maybe a bit clearance to exhast ports !!! if see a bit over original power when injected then i m ok for now i reached midle torque but lost visible over 6000 .. the engine wants to gain that higher on its own.. those engines made for rpms and i give up on that

[@eamh2002]

If the car is street legal have you tested the MPG? Just curious whats the low rpm efficiency. It can't be bad I assume :) If you rode around a track that thing must run a few extra laps against turbo cars with gasoline to spare.

[@TrueBlueEG8]

Not much point in increasing power at those high rpms, but the bump in the middle of the rpm range is well worth it, the 5deg advance with the shorter runners seems the best set up to me.

[@Garage4age]

Yeah if it was something that was in the top 2000rpm the whole time, different story. Is also not the cam combo to be chasing the midrange with. Although It actually done surprisingly well on these cams midrange wise. but still will be swapping to a smaller combo

[@TrueBlueEG8]

[@beermoneymotorsports4932]

What is your usual inlet length(end of trumpet to back of valve) that you use and what rpm are you running out to on them?

[@erwinio007]

Man I've been watching your videos religiously. I even happened to have picked up the same cam gears as you. Do you have any documentation that may have came with them or give me a rundown on how i should interpret the timing markings on the gears?

[@Garage4age]

they are vernier gears. so work same as vernier caliper. when lines with round dots at ends are lined up they are at zero. the lines around outside are 5deg apart(when lined up with the inner with dot) the other lines on inside are your vernier measurements. add them to your measurement. say if your inner line with dot is just past the outer. count the inner marks till you find the first one that lines up with an outer mark. if its the 3rd one, that means 3 degrees advance.

[@zerohikari2685]

If you could, try outboard injectors again before you remove the big cams. There might be a little more power high up in the revs with the outboard injectors

[@Garage4age]

already has a different cam combo in it. but will revisit the outboard injection at some stage, as a couple things want to try.

[@spinnetti]

Wow.. That's like Formula Atlantic levels of power!

[@Garage4age]

[@SidewaysGts]

Possible fun idea for comparison if you have access to any: Would you be willing to do a comparison with 20v ITBs compared to the 52 mm ITBs?

[@Josh.Bowen.086]

So good! What transmission do you run? Still a t50? Also, curious what is your r&p gear ratio is?

[@Garage4age]

yeah t50. had some issues changing a high rpm but threw some new parts at it, seems fine now. 4.3 diff. small wheels so its fairly short

[@ProjectoD77]

Totally unrelated to the subject of the video but... What sensor are you using for your cam signal ?! it look very clean

[@Garage4age]

The sensor on back of cam cover is a 2jz one. For the vvti setup. Not currently in use. I run cherry sensors for the other Cas signals

[@LeoKadettTouringCar]

3.7KG flywheel 😳 i want one too 😆 impressive numbers for 1.6L

[@James_Maguire]

I seen a guy selling a 2.3kg flywheel for 4age . Didn't even know it existed

[@shamil808]

My understanding of engine power is beginner at best. Why was there a dip at 4.5K and 5.5K with the more aggressive C cam and not with the B cam? And could someone explain why the shorter runner and advanced cam rectified the issue? Thanks. 🙇‍♂

[@TheUltimateRanger89]

bigger cam gives the air more time to enter the engine per rpm, moving the cam 5° got the air moving into the engine early, when the valve opens to let air in it creates a vacuum wave that travels to the beginning of the intake, when it gets there a rush of air creates a pressure wave that rushes back down the intake to the valve. if you time it rght you can get that pressure wave to get to the valve when it opens and push extra air into the engine. that dip is when the timing is bad, the pressure wave arrived too soon and bounced back out of the intake creating negative pressure when the valve opens. so moving the timing and duration of the valve opening or the length of the intake can create power. now the engine gets faster but the pressure waves can only travel the speed of sound so you can only get the timing to work perfect for a certain rpm eg 7000 or 3000 at 3000 it makes the engine torque good and easy to drive the engine on the road. 7000 can have more power but uses alot of fuel so mostly for racing cars. if you read the comments or watch the other videos they make varible intakes and cams so you can get tht pressure wave to work perfect at high andlow rpms VTEK is variable cam timing

[@Stale_Mahoney]

but the torque curve is neat and flat all the way, would be cool if you put the NM number as well as KW

[@mattk9438]

Thats gonna walk a boyracer spec mps (as in, stock with a poddy and other loud mods) if you raced one on the highway... in mexico. I raced one with a 160hp k20 powered mpv. Walked it at 180kmh. Tried to figure out how this van with a base model k20 beat a 2.3l turbo... so i googled a few dyno sheets. At 5000rpm, an mps makes 220hp. At 6500rpm, they only make 110. And they seem to have a reputation for blowing up near the rev limiter so yeah... if you keep it in your juicy powerband in top gear, youll beat an mps. With the lack of weight, you should be quicker too, despite the mps’s power advantage.

[@Garage4age]

Don't think driveline loss would be anywhere near that. Maybe in the other gears but not 4th the dyno run is done in. I'd guess mid 180's at engine. 20v doesn't seem to work as well when comes to high power na. But haven't attempted it myself

@@Garage4age See, now that's a alot more reasonable. I guess this means you weren't running it in the 1:1 gear on the dyno, and that's why the graph is reading over double what it should be for torque?

[@Garage4age]

@@Drunken_Hamster was in 4th which is 1:1 . but diff ratio and tyre sizes to take into account. roller dynos calculate power from torque applied to the rollers and the rollers speed. The dyno needs to know rpm of the engine to calculate torque from the power numbers. thats why you see on some dyno's, if the rpm pickup doesnt work there is no torque number. my dyno is running in roller speed. so just shows the torque numbers being applied to the rollers. torque is just a calculation from power and speed. power is just a calculation from torque and speed.
