Intake Dyno Test: Whale vs Short Ram vs Cold Air Intake at DynoPro

And for many years people thought the whale intake was actually more better than the short ram 😅 i always thought they made less because of it's design, it lacks velocity. Another great comparison brother.

[@keyn9r]

On my modded ~210hp B16 i had a 3.5" short ram to a 3.5 Blox VStack and filter on a ITR TB and Manifold. Changed it to a 3" CAI but used the 3.5" Filter with a 3" to 3.5" coupler. AFR got very lean especially before VTEC and between 8-9k RPM, so i had to add much fuel there. Now switched to 3" ShortRAM, because afraid of dirt and water. Didn`t notice much difference in the AFRs, so i didn't expected 5hp difference in your test.

[@SRDmotorsports]

that’s an interesting scenario that you went thru definitely interesting!

[@Scott02]

For science, to rule out oil temp differences (hotter oil temps on the later runs would allow the engine to make higher hp), it would be great if you could put the first (lower hp) intake back in last to see the power drop back down again. Then you can have the most trustworthy data.

[@SRDmotorsports]

@@Scott02 true true makes sense… this base run had 4-5min intervals total 3 runs not a 1 hour session that can elevate temps but I agree that makes sense on longer run sessions indeed

[@Scott02]

@ when i do road logging for my self-tuning of my NC miata, i have to drive nicely all the way around a decently large country block to get IAT, coolant temp, and oil temps to get back to baseline levels after just one pull in 3rd gear from 2000-7500rpm (so that my results are not skewed). And if you watch the Garage4AGE youtube channel, he occasionally shows how much elevated oil temps can impact the outcome of the dyno session. Keep up the great work, I just thought i’d note this for future videos for you!

[@SRDmotorsports]

@@Mike-ry4ti yes sir! The fun def continues

[@gabrielvieira6529]

Hello! This test is awesome. But I believe that the results only got better because the intake was longer, making the (Theoratical) air speed faster, thus making more power. It could have been so good because that's an engine that pulls much air at higher rpm's, so it helps with the air speed. I wonder if you could redo the test with a non VTEC engine!

[@SRDmotorsports]

@@gabrielvieira6529 the earlier test was a VTi but with a stock airbox it’s called a vtec but it’s like a y7 with roller rockers and only goes 16 lobes on vtec so essentially it’s a non vtec Check out the results rpm limit was stock at 7,200rpm

[@SRDmotorsports]

but forgot to say “finally” someone who didn’t get too excited and got their panties in a bunch with the name “cold air” Intake I agree on the length though as u can see similar gains when running a velocity stack out the headlight but strapped on the dyno so it’s at stand still… the length does the work initially

[@gabrielvieira6529]

@@SRDmotorsports Thanks for the reply. And I might use that lenghty intake on my car also. Some say it can increase torque. Also it has a very nice sound. Cheers and success with the channel!

[@SRDmotorsports]

@ you’re welcome man! and thanks for checking this out… And I agree on torque and we called it “AEM hump” Back in the day because AEM had that cold air intake length and the hump pertained to the 4-5k rpm torque hump which can be seen here ideally we know that’s a range we see often driving normal everyday so it does help 😎

[@craigsawyer6453]

With my B series engines I got more gain from headers than intake. Perhaps headers would be a good future video?? Dangerous slope, after bolt on mods comes the real money mods.

[@SRDmotorsports]

yeah

[@martinp8427]

Headers always serve a dual purpose - first they allow the exhaust gases to exit the combustion chamber faster compared to the stock manifold as well as improving pulsations and helping the intake valves to suck in more air, during the valve overlap phases.

[@SRDmotorsports]

yup 😎

Would adding insulating tape/material to the tube specially for the aluminium would give more "Cold Air" to the engine? Watching from Hull, UK

[@SRDmotorsports]

@@whinmps that’s true and especially if it was a D series… maaaaan dseries induction noise goes hard when upgrading intakes

[@Built_it_by-alex]

The more bends an intake pipe has, it will make the air bounce and tumble as it travels towards the intake valves which in turn create somewhat of an forced induction, there is more science to this than you think, like for instance pipe diameter and other thing's

[@SRDmotorsports]

don’t forget “constant” diameter affects waves too

[@a124as]

I believe the length of the pipe allows for more smoothing of the air creating a more consistent flow rate through the diameter. Thus creating for power

[@SRDmotorsports]

@@a124as yep! And as I stated at the shop page the reel I made there, the “length” actually stacks columns of air if one can visualize it that way and even when the plenum is full or almost full… the sheer momentum brought by that length gets to “stack” or stuff more IN yet we see a few get stuck and focused on just “temperature” factor due to name cold air

[@Sheenhunnit]

Pretty much cold air intake acts like a small turbo

it helps reach above VE at certain points in the rpm

[@martinp8427]

Man that whale intake leans out so much below 4000 rpm! I have two ideas that you can easily dyno test and some theory behind the second one as well. 1. Look at the whale intake and flip it the other way around, it looks like your throttle body radius intake, doesn't it? (wide size pipe of the intake pointing to the throttle body) I am sure that you can find two silicone hose reducers that can be attached to the wider part of the whale intake, which is what, around 4.5"? So you go from 4.5" to 3.5" or even 3" to the throttle body directly (I don't know what's the size of throttle body diameter on those engines. 2. I also commented again on the last dyno run when testing CAI, but maybe my comment got lost or removed due to the link to an external blog that tested B16 intake pipes diameters. The 3.5" intake gave the best results in torque and power across 6 different intakes in total, also in the lowest peak rpms. If it's allowed or if needed, I can put the link to the blog again here. My theory why bigger intake diameters are working well is that as you have noted, they provide more pressure. Most people think that airspeed is the key, but in high rpms it isn't. Also, just like aftermarket exhaust manifolds that often come in bigger sizes than the stock ones - larger diameter pipes reduce air temps and provide cooler flow.

[@SRDmotorsports]

Good observation right there and I agree the whale can be improved and changed , sadly it will be very far from how people use it But there are a lot of things u can improve on “each” of the three intakes indeed

The CAI is a cheat, of course you are sucking "cold air" or ambient temp, you will probably notice a big difference when the hood is closed or in actual driving. Check IAT with obd2.

[@heaycekz]

@@SRDmotorsports Is your engine modified? If it is then you will mislead people with the gains achieved. Because if your numbers are right in real world application, then anyone looking for more power should buy a CAI and gain easy 10whp +7 wtq which I don't think is the case for most modern engines. Maybe the gains are specific to your car model? There are a lot of yt videos about CAI being dyno tested and there are no significant gains. Just added noise and a better looking engine bay, of course if your engine is modified the case would be different.

[@SRDmotorsports]

@ it’s a stock b18 just like the earlier video Like I said almost everyone misleads themselves with the “term” cold air I can understand it some “cold air” dont give gains just notice = check the overall length and we tested all 3 intakes that anyone can buy in eBay they can do the same test just make sure to use the same “length” cold air intake not just by name

[@RAPTORB26]

​@@SRDmotorsports well I hate to tell you this but 6 years of ice racing championships in my family and it's hard to say the engine bay don't get warm cause even at below freezing temps the engine bay is still hot enough to melt snow and ice off the hood and keep the hood warm to the touch. See for your theory to work the cooler outside air needs to flow into and out of the engine bay as fast as it went in . But here's the problem it can't to do that there's this big hot restriction in the way called a motor. And lets not forget big air dams behind it, above it and on both sides called a firewall a hood and left and right fenders. And where do you think the heat from the rad goes that's infront of your short ram intake? That's right in goes back into the engine bay heating that cooler air up as it travels through the rads cooling fins to cool the rad and the engines coolent down. That's why most cold air intakes get thier air from the front as close to the cooler air coming I to the engine as they can or from down low closer to the cooler air at the bottom of the engine bay or directly from a hole or scoop in the hood.

[@SRDmotorsports]

@ alright I hear you and don’t question your ice racing experience for sure… at max 40km/h we see no more than 13deg difference on a stock car ambient temp and engine bay temp… it’s not my theory it’ has been tested way back in 2006-2008 by someone in the US and then we did too in 2008 just never got to take vids of it so gotta re do some now…
