I still think the Nissonda numbers are impressive regardless if there's there's variance in peak readout between the different dynos. Literally 400hp is awesome considering all the hell the black z was giving you. Side note, you guys should care less about what negative commenters say. We aren't there building cars, we're watching lol. It's a whole different story on your side of the camera
I 2ed that regardless if the dyno is 10-15% forgiving. The ability to repeat the same # and see gain after change is what matters.. too many people get hung up on the HP # when it literally is just a #. As always great work.. love that car lol
Nailed it with the dyno discussion-the real piece to consider is the delta. Whether the dyno reads high or low is irrelevant when trying to dial in a car. Being able to gauge improvement/gains from base numbers to tuned numbers is the key, and of course the dynos consistency is important. The one thing this video confirmed-FedEx sucks donk. Always have.
All Jimmy needs to do is recalibrate the load cell on his dyno. The difference between a braked dyno and unbaked is the braked dyno actually measures the torque using a sensor. Dynos like a dyno jet calculate the torque by seeing how fast it can spin a specific weighted roller. In theory once calibrated braked dyno should be more accurate.
People get all into the numbers of dynos when really you're just using it as another tool to tune a vehicle. And then if you get a set number and you make some changes and you want to see if it approved , you can.. so as long as you're Dyno is consistent within your own numbers that's really all that matters.
Im guessing valve seals i was about to do them in my ka but it ended up being the turbo itself. It could be the turbo itself or not enough restrictor. I was smoking bad on deceleration not so much full throttle.
I’ve been saying this for years but people don’t listen, I’m okay with keeping these cheap and readily available so I hope people stay on the overpriced SR hype train
@@THESKINIMIN1234 since I watched this video I was thinking to start working on my KA before my RB, if I could make 250 ish 300 on pump gas I'd be happy
I don’t even have a 240 but I saw a whole KA with harness trans and ecu for 150 and had too save her from the junkyard now I gotta find a way to install it all into an s10
I sold all of my schassis but still have my ka bc 264 cams super tec valves springs and retainers cp pistons forged rods arp studs and rod bolts. Guy i sold my last one to said he was going sr and i laughed kept my built motor gave him a stock one i had laying around.
Doesn't really matter if it's alittle off or not. The Dyno is just a tool to get the tune dialed in. The hp and TQ numbers help with the tuning processt
Torque isn't really what the dyno measures, it's power. It works torque back based on the engine RPM. Average power across the useable rev range is what's important to the driving experience since power determines directly how much you can accelerate at a given wheel speed.
Loving the Nissonda content! That thing's gunna be a weapon with a built motor 😱 totally agree, the repeatability is what matters with a dyno. Tuning is about the drivability of a car not the numbers. But people always talk about the numbers because that's the thing they can compare
Would love to see an AE86 on the channel. Love all the vids and your crew and friends really seem like some cool people. Can’t wait to see the Supra build
I thing vaps more than DJ does lol jk love the channel man.. . love how much attention to detail you put in every car you build . it’s killing it . Much love ❤️💙💙🖤🤍💙❤️💜❤️💙🤍
I've got a 93 civic that made 320whp on pump gas on a 'heart breaker' Dyno (Xenocron in NY). I'm in CT, was thinking about having Jaimie Marsh check the tune and maybe add full throttle shift, and rolling anti-lag. Would be interesting to see what it makes as a baseline on your Dyno.
@@joshuabower61 it's about to be a year since I finished it, and don't think I've seen anyone from any of the forums with similar builds have any problems. The transmissions are known to go at or above 450whp. I've got a helical LSD. I do baby it on shifts though and haven't launched it, still have to set negative caster on the traction bars. I haven't tried the anti-lag either since it's got a 3" hi flow cat and full exhaust.
@@NonovUrbizniz yeah just like any Honda tranny it’ll hold a fair bit of power but shifting it hard with that power is what breaks them. My buddies made d16y8 made around 315whp for over a year and he went through 5 trans in that time. Another buddy had a vitals kit in his never dynoed but probably high 300s to the tire and he went through even more trans. You must have a healthy motor for it to hold for that long my friend 🙂
I think that's the most rigid Honda next to some time attack cars I've ever seen it stays so flat And he mentions it want to stay straight..looks like it it really does
it would be cool to see you do some dyno pulls with all of your older cars that you haven't tried on the new dyno yet. i only saw bits of the Zs when you made videos on them, what will they run
12% off on the best torque figure (which was incomplete) but noone talks about the 20% on the horsepower figure.... When you dyno a car you ask about the horsepower number, not the torque... You could admit that there is a problem with your brand new dyno but sponsorships keep your lips sealed....
Dyno is in the end a tool for tuning the engine, keep it happy, the numbers are cool but more of a by product of the tune, and to compare gains or losses.
I own a dynocom aswell you need to adjust the load settings to get accurate readings .. thats why your dyno pulls are so short and quick .. I used to make the same mistake with the dynocom.. Turbo cars I put the load at 20 percent All motor I do 12 percent .. Trust me try it you'll thank me later
Is it possible to scale the dyno slightly down now that you have a bit of a reference point? Pretty sure majority of people watching couldnt care less about the numbers anyway so I wouldnt stress too much about it
Just a thought, but now that you know the variance between your dyno vs others, can't you apply a correction to the power readings? Correct power readings by ~12% or something?
Yep, there are a number of ways you can do correction factors, some just +/- a flat %... others take in the weather, as that can make a noticeable difference.
@@wobblysauce Makes sense. In this case, Jimmy did mention humidity. So I’d attribute 2% to weather and just make a round 10% correction. Either way, as long as he can make runs and see deltas the Dynocom is doing it’s job.
@@LukeViozzi That it is... and for that price, it does it well. But as Jimmy has stated also, there are a number of other modes and features it has but they haven't really played with it.
If power is just a function of torque related to wheel speed, why would it differ from one dyno to another, that would have to be some calibration issue or i dont know
testament to E85 goodness. surprised that thing still has pistons and ring lands. wonder what the C5 would make on Jimmy's dyno in comparison to turbo mike's...
It seems like the dyno ramp speed is at like 700rpm per sec. A tad high, there is not as much load at high ramp speed. It could make the difference. Also HP is work over time. Torque × RPM / 5252 for lbs/ft And it's 7127 for NM.
Jimmy, I know everyone in the industry uses the Dyno Jet as a standard but it shouldn’t be. It’s the least accurate of dynos. When the people at Dyno Jet were working on their first dyno they couldn’t come up with a good calibration. They ended up slapping a Yamaha VMax on the Dyno and matched the Dyno output to the motorcycle instead of the other way around. Because of this the Dyno Jet will give out different inaccurate torque readings depending on which engine is being dynod.
Whats important is that youre able to do good tunes on it reliably. You can always play with the calibration later if you want a closer match to a dynojet
It's probably been ran so hard and has so many miles on it. That its wore the cylinders out so much that the rings won't butt together and buckle, that would be understandable for the all the smoke to. I believe that's what could've happened here. I've always heard a loose engine is a happy engine. Can't wait for the comments lol.
