I use these rods in my Audi 20vt 5cyl, I'm running 30psi with a 76mm borg warner and spinning over 8000 rpm. They work.

I used these rods in my FJ20ET circuit race car engine pushing 500HP with no issues so far. I did have them resized for safety and I filed a small u - shaped groove in the top side of the big end to oil the gudgeon pin. Mine too were within 0.5g. They have been over-reved to 10000RPM, spend their life at 5000 to 8000 RPM and after 4 years I pulled the big end caps off and the bearings were perfect. Good value I reckon.

Normally an unboxing video wouldn’t be that interesting or informative... but when it’s you and car parts, it’s definitely worth a look! It’s been a while since I saw someone give a level of detail close to what you do here. You really did the research, and read through other people’s testing and research. You discuss many aspects of the product, always with your lovely personality and humour nearby. I’ll admit, I have the negative bias towards products made in China, but you help to correct that with the age-old phrase “you get what you pay for” and with the quality assurance the company has obtained. There are some very premium / luxurious products made in China and we don’t question them despite insane price markups. You’re doing it the right way; researching the products you will use and getting that balance between cost and quality. I love your videos. Thank you!

MaXpeedingRods was very awesome with customer service for me. I have a VW Mk3 Cabrio with MaXpeedingRods and I was a bit careless and had dirt in the threads while applying torque to the arp bolts, one of the bolts locked up and I had to use a breaker bar with a jackstand handle to completely break the arp bolt off just so I could free the rod and get it out. I sent them a picture of my mistake and was completely honest how I didn't clear dirt out of the threads and they sent me a new rod free of charge... I have no words... but respect.

We did use maxspeeding rods in 700hp straight six and no problems what so ever.

I'm using these rods in my VAG 1.8t 20v and I'm very happy with them, great quality stuff and no issues with 3 years of abusement

One more little thing is the hole in the wrist pin side is definitely drilled a bit off center. Otherwise they do look like a good rod for the money! Great overview.

I was always curious about those rods.

I love your no nonsense approach to things, its is very refreshing in a sea of marketing mumbo-jumbo and people jumping on the bandwagon to spout the same nonsense without really thinking about it. I have Maxspeeding Rods suspension on my track car, and despite the hate they get in the car crowd - I'm sure mostly from people who have never even fitted a set - they have held up very well for 4 years, once setup they've been brilliant.

I have nothing against China made stuff. They use the same manufacturing techniques anyone else uses. But they just lack quality control In some cases

Let me just get my gram scale. That I have for.... um.... weighing saffron.....

Running these supporting Ross racing pistons in my blueprinted silvertop 4AGTE and no dramas yet.

7:35 at least 7afe rods hold up to 400hp at 8000rpm - at that point they start to bend (tested with arp bolts) so they are strong enough.. just look on d15/d16 rods, they are thin as pencils and still make 280-300hp. yeah HP rantings are useless, it depends more on weight of the piston and revolutions and as said by knock really what engine cam make really depends on ring gap :D and ring gap doesnt depend on mileage

Cool, you have a Mk1 MR2! I used to have the Mk3, that was a great car but I haven't driven the Mk1. I will follow this project.

They look pretty much like the Manley rods I put in my 2.3DISI-T engines (MPS/CX7). P.S.: don't swap the caps between rods. they have some markings on them, should be easy to pair them back.

My rear brake calipers are Maxpeeding Rods! They fit perfectly and stop as they should. I got both sides for half the price as 1 OEM.

I love how he explains all this and the Brian Crower lightweight rods I have are literally the same… good stuff either way just paid more for them

I've had a set of them in my vw 1.8tfor 60k miles now....

Rods should also be weight checked end to end-little ends should be very close in weight to one another as should the big ends.We used to check end weights on A series (mini engines)with approx 120hp plus(plus lots of revs- 7k regularly)-more measuring/more accuracy=longer life.I'm sure it's going to be even more important with the hp you're intending.(Obvs we were using OEM rods with a bit of meat on that could be ground away to match-Hopefully forged/machined rods should be really close.)

Using this on my EJ25. These rods are great! Worth it.

Maxpeeding is a play on the words “Max” and “Speed.” It rolls them together into one word, using the “X” sound to replace the “S” in speed.

“Project underdog” is the name of every college students project car.

Used them in my last 2j, 603rwhp@22psi-825rwhp@36psi e85. No issues. Using them in my current 2j and swapped a set of sr20 rods to my mate for z32 parts 👍 I like these parts.

LOL. Loved watching you have fun playing around. From the Peekaboo box to, well, I guess a rod's hole makes a reasonable substitute for a paper towel core telescope!

Unboxing is always best when it's not just at Christmas time.

Amazing video and a very honest man

Nice seeing maxpeedingrocs sponsoring the channel, congrats

Great I had looked at these but had my doubts but I think I’ll try them. Thanks

Running these I’m my 2j. Making 966whp for a year or so

funny thing is i have a set of these for a 7a with the small end sized for floating wrist pins, and when i got them they came in a plain cardboard box. I really need to start this 7age build one day. I cant wait to see the 4a build

i thing this man is going to put a pretty large turbo on that engine!

Maxpeeding rods makes some of the cheapest aftermarket suspension with mixed reviews, didn't know they made rods

Can you make a video on conrod bearings and oil starvation ?

Yea that’s like tools that say “assembled in the USA from parts made in China”

What really should be done to be able to judge if these rods are alright: professionally MEASURE straightness, big end roundness, big end taper, small end diameter and proper balance testing, not just putting them on a scale. But I do agree that probably 90% of aftermarket rods are coming from Chinese factories. The real issue with made in china is, when there is no second quality control, because that is the weakest part of made in china. If you want to be sure, check and measure everything, or buy from a reputable brand where this has been done by them.

Homie got the bud scales

That flaw is exactly what I saw on my set of rods. Can't complain at $165 for a set of 4!

Diy mike built a 10 sec honda with those rods

They come from the same factory in china that alot of 'insert named brand here' come from as well that claim to be made in the USA and alot if other countries..

‘Balanced’ doesn’t just mean they weigh the same. Thanks for the video, was wondering if the brand was any good.

I believe Hoonigans S*it car was sat on Maxpeeding rods coilovers ant they survived everything

great presentation. clear and informative, and also a great intuition for what are the stupid questions people will want answered

I use the same rods in my 4age with Honda b18 turbo nippon piston it hold 25 psi on a gt35 turbo I love it no problem what so ever

Lovely rods im adding to my order

A torque rating on rods would make more sense than a horsepower rating because the torque is what's going to break them.

Imma grab me a set of these for my VW engine build this winter.

You should also measure the big end machining tolerance. Big end machining tolerance across axis should not lesser or higher than 0.001. These rods big end machining tolerance is 0.005. That is big difference for a connecting rod. Well-known brands machining tolerance of the big end section is spot on within +/- 0.001. It won't destroy your engine right away but would cause issue for long run.

hey i'm building a super charged 4afe with a SC12 and this will put me on the right path :)

Alibaba rods, buy them directly on Alibaba they are cheaper there. You can also chose what they will laser engraving on the rod

I initially got the maxpeeding rods for my Volvo, but I ended up reselling them because the web thickness was inconsistent and the finish was pretty rough, I wasn't comfortable putting them in my 700ft-lb torque Volvo engine build. I ended up going with AUTOVERDI rods. They only do custom rods now after China fakes nearly ruined their reputation.

If that's truely 4340 it's not a bad price, but I only have knowledge of Chevrolet, SBC engine components. I have a balanced rotating assembly, made from 5140, I wouldn't mind next time going with 4340 H- beam rods, but being a 6.3 litre, 385 cid stroker, only revs to 6,500-6,800 , and makes around 650 hp. my next engine will likely be smaller displacement, and rev to 7500+, H beam being lighter, it will work better in high rpm engines, just saying, I know you know this,

Maxpeeding rods as stated on the box are very good. Not a copy of more expensive brands....are the same thing. Company buys them, drills own hole....calls it their own.....they don't make parts like this....not many companies do because the cost to produce it is massive, don't be fooled.

Yes!! Finally a Person that thinks like me.. this is very true, i owned 3 shops and the true is almost all parts are made in china and rebranded with the company logo, all you need is verify the MATERIAL of the parts and dimentions, thats all. Iphone, Sony, Xbox, Playstation and a lot of companies buy from China and re-look or re-brand.

Nice, thanks Mr. D4A! Tip top tips!

The term is " stress riser" .

You Never disappoint, thanks

Those rods look exactly like my eagle rods!

i just bought a set because of your video

He he, I like your pronunciation of genuine. Looks really good.

Will be made by Hurricane Performance in China. Hurricane performance manufactures many other brands of forged rods, cranks etc such as eagle, PEC, scat, K1 and many others in Europe and the USA

I'm surprised, the quality seems good for half price of any other 'fancy' brands.

im a noob but have the same engine and same goal so its nice to have someone who knows whats up holding my hand through this

I use them too... they are nice...

Great Video as usual, looking forward to next weeks video🙏🙏🙏

I bought these rods a few weeks back and checked the big and small end diameter with bore gauge with everything in spec! Nothing different in measurement difference from big brand rods. also balance between rods big and small end are with in spec! Only thing to note is the hole in the bearing cap to the bolt is a little bit big...

I just so happened to be looking at all those Chinese rods and was wondering.... Now I might take a closer loook.. thanks for posting

Hey I’ve just bought these for a 4age and I’m sending them back look at the counter boring on the holes mine haven’t been reamed at all lots of high points.

I just bought those for my d15b Honda turbo built

Like your videos,resently subscribed on your channel. You make it easy to understand keep those videos coming you're one of the best in these kind of vids

You should have saved this till when u had tested them and did a full vid . I’ve watched a few of your vid 👍. I’m building engines for 20 + years , and I have only seen 1 set but from what u described the shot peening wasn’t done right , inside the beam but what I seen , they are arp bolts but the tapped part in the rod is excessively loose , remove the cap and treaty up the bolt it’s only till the end they feel near right

If you sand to take the roughness on the rod make sure you shot peen it again. The shot peening is to decrease the stress on the part

I would also get some slots machined on the sides of the big end cheeks to spray oil on the underside of the piston

Awesome videos! Keep up the good work

Good video with true facts.

Man I like your channel and you are good from maxpeedingrods i bought same turbo and they are good for what im paying

the weight from the rod is not only measured in full, but the 2 sides appart for dynamic balancing: this need a special weithing scale with 2 pins...

Those rods look clean and very good

Can you talk more about H-beam vs I-beam rods?

Again very nice video. To be a viceguy, you should look not only for weight overall, there is a rotating and ozillating mass 😉😉. Wish the best for your built ✌👍👍👍

Just found that channel , better than Netflix 😂😂

Very Good Video, Greetings from Germany

Excellent review.

Very detailed and informative, will you be doing the same thing for pistons as well?

Another awesome and informative video. Thank you

dont think I suggest you remove material since its already in-spec and balanced with each other

Would be nice to know about their crank shaft too

more info I'd like to see is how centered are the holes, and what are the dimensions of them, how many thousands are they out of spec? how balanced are they the weight even across them? might need more then vernier calipers for that I think..

Conrods? Those are PeedingRods!

just a note - shot peening not only makes the surface clean, but it also work hardens it (think of it as thousands of little hammer blows)

Iam very happy with mine.

well they look all conclusive so its torque strength thru will be whatever it is, then just check the clearance, deminsions and weight.... but id weigh em comparative from end to end .... micrometer, digital calipers.

I've been loking at these rods too, still not sure if I should just stick to my original late bigport rods or upgrade for these when I'm planning to make 4A-GTE with ~250hp.

thanks for sharing, might get some for my subaru build

Nice choice, they can handle a lot of power. Will you need to clearance the block ?

With you removing the little sharp corners makes these rods "finish machined" at home :)

If you are going to start getting rid of material to clean up and de-burr sharp edges/corners, be mindful of the change in weight and balance.

Very interesting!

Nice preview, sadly they don't make any rods for Mazdaspeed 3/6 :( I would have placed an order just to feel safe, because my Mazdaspeed 6 has a big fat torque curve down low and these engines are bending rods like spaghetti. Imagine having 270Nm torque down low at under 2000rpm on spaghetti rods.

SO what what is the user experience in the end? did they survive the usage? increased wear, spun bearings, anything odd?
