I legit don't understand how this channel is not bigger. The content is gold, the commentary is up beat, and the intro music gets my bobbing lol! I get so excited about seeing these on my news feed.
This is not a negative comment but this type of channel is appealing to nerdy type gear heads like myself. There is a limited number of us out there. The big time automotive channels are produced like a reality tv show which does not appeal to me I am here for the information.
@@MRBoatwrights Agreed, too many people just want fast 60ft and ETs, burnouts and other shenanigans and don’t care how the HP was made. If more people watched Richards content they would know how to optimize their setup and/or learn why their setups aren’t doing what they expected.
Channel obviously deserves to be bigger. I think the problem is that he proves all these little rice burners or want to be enthusiasts to be wrong. For example there's no such thing as a boost cam or turbo cam. And God forbid he says a bigger turbo isn't better
Easy thing I was taught: 2 high 1 low value of: Compression Amount, Turbo Size, and Engine size. Another thing to note about turbo sizing is that, big turbos can help with fuel economy by keeping an engine off boost at cruising RPMs, and help to control EGTs and engine tempratures. With the awesome housings and wheels these days, and even VGT or twin scroll setups, its great how tailored the geometry can be for your flows and pressure ratios.
Thank you. This was great to see. I was worried that I would always have oversized turbo problems, because I am interested in turbocharging small single and parallel twin motorcycle engines, that are around 200cc. If the smallest turbo I can find is still useless at half or even 2/3rds rpm, then I accept that, for either low rpm economy, or, I will just use electric motors to handle low rpms and launching out of a corner or dig, and have the turbo handle sustained high RPM power, that EVs struggle with. Parallel or Series Hybrid, I'll accept this.
Richard talking so much sense as per normal. I have a street car 5.3 ls. Its a daily and i catch a ton of flack for my tyrbo choice from the ls community. Its a single s366. And it lights like a candle and makes an easy 5-600whp. Thats all im looking for in this car so why would i size a larger turbo? Im making positive pressure by 2500rpm and am walking away from all kinds of street cars before the even realise it. 800, 900, 1000hp is fun. Dont get me wrong. But a torquey street car with good turbo response is a blast too drive around in.
Re: long tube header. What I’ve noticed is that longer headers allow the charge to cool off more and give the effect of a larger turbine. By that I mean reduced back pressure and a less responsive turbo.
Good video Richard, I think we all.love boost, nearly as much as you do! It always makes me think that if you mirrored a Honda dyno graph it would look like a standard v8 graph lol
I run a 46mm Garrett gen 2 on a 2.4l with no variable timing cam and a 6500 rpm redline. Def on the small side but spools damn near instantly. Stock cams and my powerband falls off after 6k pretty drastically. But it’s a primarily street car and still very fun, not often I take it past 6 unless I’m racing
I really love this channel but I wish I could actually see video of the engines running. Everything else is great but a short clip of the engine making power would be amazing
3 isn't tooooooo bad I had an rb25 with a td06, vct still and 4.3 gears. I had 23 psi by 2500. Being able to open the gate at 60kms an hour in fourth gear got old really quickly.
I have a ka24de on a gtx2860 which is way small for that displacement. Needless to say, it’s always in the powerband but falls off past 6k due to stock cams. Street car with Instant spool tho
Dads 4.0 falcon went really good was responsive, then they went bigger size bigger wheels, don't feel exciting anymore, it would need ultra low gears to get that power down & more revvs, whenever they suggest mines too small i resist they all say it.
One consideration for oversizing a turbo is too minimize bent stock rods and or broken pistons. This might be a consideration between two turbos that are close in size.
EFR is also one of the most if not the most advanced aftermarket turbo available right now. Will out flow turbos with older tech twice its size. Leagues ahead of The Garrett GT and GTX series and still better than the G series. Watch TurboDirect S.A if you want to learn all about it.
Billet 78/75 should be just about perfect for my 400 BB mopar. Responsive TQ and decent HP for a DAILY DRIVER. Everybody wants a BIG block AND a TURBO!!! 😝
Okay....A commercial application on a Kubota V1505T engine with a TD025M turbo. Will a TD025 Turbo offer any benefits? The TD025 is slightly larger and used on that engine for Bobcat applications
Richard, this test is between the biggest possible for street application and a ridiculous sized turbo for both engines. In a much more credible comparison would had been between a T3/T04E for the K24 and a some kind of GT28xx (a 2867?) for the B16. Also, since it's a turbo test, you should give more details like turbine housing a/r size etc.
V8 guys can have backpressure issues.make sure not to go to small it’s not worth the problems. be patient LOL or get a small camshaft to help down low you’ll thank me later
Can you do this on the Ameri-barra. I’ve always wondered what that motor could do with a smaller turbo oriented for lighter duty truck applications. Why should Dodge be the only one to get turbo inline 6 truck power
This makes me think about extreme upsized turbos on compound boost, since responsiveness increases and a mechanical can still cut them at top it would seem easy not to go over.... I don't really know anything just thinking
Idk if youve made a video on this before could you do a video explaining and testing turbo A/R and the responsiveness or lag there of say between like a 0.84 and 1.25 or similar
This is just for the pig iron of it or u may point out something I missed , so I seen bk to bk if garret and persission turbos there was a Hugh difference in the , but this was years bk , and I know u did these tests with stuff lying around but maybe keeping the brand but a bigger as the k24 the bigger turbo should not make similar Bhp at the same boost it should be less psi but yet it is so us this showing up the point of the cheap turbo
Have you done a video ahowcasing the affects of to small of a turbo and what the data results show like restriction boost and gead ect? Also what about having way to big of a turbo. This video shows boost lag pretty good but can you have to big of a turbo and make almost no boost?
yes-take a look at the video where I ran a GT45 turbo on a 454 BBC-very high back pressure. As to running too big of a turbo, if you keep increasing the size, you get more and more lag until the motor can't spool the turbo
Is it possible to run a turbo on a 390FE w/ trick flow heads at approx. 10.8:1 compression on pump gas. If so, what turbo would give that responsive low end power.
Have a cj-5 with a 232 -6. Want to pull stumps. Lol. What would be a good turbo. I I’m kinda new to pressure. But .030” over pistons, small cam, and Offenhauser and 450 CFI 4b. 3 speed manual.
Holset hx30 would suit you, do some research and look at dyno graphs on the internet to figure out which hotside is best for your displacement and needs...smaller hotside means more low end torque and less top end power.... also go to this UK website called stavtech and look for his holset articles...he lists correct exhaust housing cm To AR conversion reference which is key for you to figure out what's needed to pull stumps a little faster or pull on other cars
Thank you! Would a junk yard Honda turbo be in the ball park? Also, would the Chineseieum turbo last? I know they do well in a Dino but would they last? Do they have bearings or bushings for the turbine shaft?
Out of curiosity, have you had experience with s252 or s257 borg turbos on these k24 motors? I am about to place an order for one of them, but am really curious if the 5mm differences will be extremely noticeable for a street build. I've never had a turbo car before so I'm just curious about what your experience is with these sorts of motors
Interestingly on the last graph the No,s at the start of the run were the same before they diverged. Is that a result of the way the dyno was loaded and then the transient rate of acceleration during the run?
