I've already touched on this in other threads, and never ended up buying any because of other people's wildly different experiences of them, but I've noticed a few interesting things on the internet of late and given the current political situation I figure this may be the last chance to get the Hong Kong version of Maxpeedingrods components before they disappear for good, so might finally take the plunge and buy a set.

https://www.maxpeedingrods.co.uk/h-beam-connecting-rods/alfa-romeo-conrods.html

What are people's general experience of these rods, either from their website or the numerous Ebay stores? And has anyone compared them to other H Beam rods?

There are dozens of other rods which look near-identical to the Maxpeedingrods, and I know they can print anybody's name on a set of rods for $5 if you order over 10, so I wouldn't mind betting 90% of the other mid-price H Beam rods are actually the Hong Kong ones (or their even cheaper Chinese clones) just with that $5 addition If this is the case it makes the others seem spectacularly poor value for money, esp as one or two of the other manufacturers use exactly the same 'quality documents' as maxpeedingrods...

But even more interestingly the experience of Maxpeedingrods seems to vary wildly depending on whether you bought them via Ebay for £50-100 less, or direct from their website. And a quick look through some of those Chinese trading sites reveals why - you can buy identical looking rods (with the Maxpeedingrods logo on them) from China for under $10 each, and I've noticed this rather interesting comment on https://uk.trustpilot.com/review/maxpeedingrods.co.uk

"We are the offical site of MaXpeedingrods. If you have purchased auto parts from our website but are not satisfied with our products or services, then welcome to write to us and suggest improvements.
However, if you are buying from eBay, we recommend that you go directly to eBay to leave a valuable customer review or seek customer service.
In fact, we and Ebay stores are two completely separate departments."

This seems incredibly fishy, I wonder if the Hong Kong manufacturer has been told it can't expose the much cheaper ones made in mainland China as counterfeits? Or is it just Maxpeedingrods being truculent about being undercut in the 'Bay? Or are the website, Ebay and Chinese rods really identical, which would mean you have an equal chance of getting a good set or bringing the insides of your engine home in a bucket however much you paid for them?

I'd be very reluctant to buy any off Ebay given they may be cheap knockoffs of already cheap rods, but is it worth the risk of looking at them all, or should I just save up pennies for the next 500 years and buy some super-expensive 'big brand' rods instead?

That is some good and useful research. Have you tried writing to maxpeeding? I did some weeks ago and still no reply.

They used to perpetually spam a Vauxhall forum I was on before I got the Giulietta.

A guy in the US reviews them here


Plenty of other reviews on YouTube.


I guess the usual cautionary advice applies for any Chinese purchase:
Warranty
Expense of returning overseas
Communication gap

Not recently, but they replied in very good English a few months back when I mailed them. Hope it's not too late for the poor souls already :(

Communication gap didn't seem too bad when I talked to them previously (unless Google Translate was working exceptionally well that day) but once again that review was of Ebay coilovers, which could well be made by a separate Chinese company. OTOH that review didn't seem too bad all things considered (they didn't snap at least) and I don't think I'd fancy trying a set of cheap coilovers wherever they came from, thanks :D

And as for the expense of returning them, there wouldn't be much to return if they did fail (a jiffy bag would probably suffice) and they'd never cover the cost of repairing the damage to your engine, so I guess that'd only apply if they were obviously bent or ovalled when you got them, and in that case I definitely wouldn't risk carrying on with the experiment.

The ideal would probably be to get them sent straight to a metallurgist for quality checking and then straight off to a machine shop to check the straightness / ovality, but if you're doing that it might be more cost effective to buy 20 of the cheaper Chinese clones and hope you get a good set of 6 at the end of it.

According to their Whois info it’s an alibaba supported site.
Yeah, I saw that too, and I noticed they do advertise on Alibaba, but they're listed as based in Hong Kong (the clones are from China) and they're considerably more expensive. That could just be a marketing ploy, but equally it could be another sign there's more than one Maxpeedingrods.

Edit: Interesting, they've disappeared from Alibaba now, but they're still listed as a Hong Kong company:

But their Alibaba clone is only just over the Chinese border in Guangdong.

Heh, I've noticed something interesting in this discussion and general searches - Alfa owners are much more open to Maxpeedingrods than many other forums.

I posted virtually the same question on a Subaru forum, and the almost universal response was "don't go anywhere near cheap Chinese rubbish". I guess the reason is twofold:

1) tuned Subaru engines with forged rods / pistons generally push out over 150bhp per litre and rev to 8000 rpm, so I guess around 75 bhp / litre at under 7000 rpm is going to be considerably less demanding.

2) There are dozens of 3rd party rod manufacturers for Subaru whereas there's only a handful for the Busso and most of them are over £1500 for a set, so are Subaru owners spoilt for choice and therefore more snobby whereas Alfa tuners have to have the attitude "beggars can't be choosers"?

missed this but im sure jim k said hes used them .. i sure in a relatively unstressed engine like alfa where you rarelt here of normal rod failures maxspeeding rods would be ideal .. though im sure standard rods with better bolts would manage most applications .. i,m sure i looked and even the weight savings were not massive

Indeed, and you can save quite a bit of weight off the standard rods by shaving the pads off either end. Then all you need to do is have them shot peened and you've got a set every bit as strong and light as any of these third party sets. And there's even some argument the original I section rods may be a stronger design than H section for V6s.

Only trouble is getting a good set of original rods to do that on - new ones are quite rare and not cheap, and 2nd hand are likely to be worn, ovalled and twisted to some degree or another so will need expensive rectification before you can even start on strengthening / weight saving. And then on top of that you have to consider if you want to invest in ridiculously expensive ARP bolts to make sure the big ends don't fly apart at high rpm / load, though whether that'd be necessary in a Busso, esp a 12v, is another matter.

Actually, that's another good question - big end bolts. Does the Busso, esp the 12v, need anything as strong / expensive as genuine ARP bolts to hold the big end caps on, or would the standard ones do?

And are there any cost-effective alternatives to genuine ARP bolts (which are massively overpriced for what they are) other than the Maxpeedingrods 'own brand' ARP bolts?

Im guessing new standard ones would do.. yet to see any failures .. though depends on spec. unless going solid lifters your never above 7000rpm and not going big boost then nope cant seen a reason to spend money elsewhere ..

https://www.partsworld-uk.com/collections/alfa-romeo-156-spare-parts/products/con-rod-alfa-romeo-2-5-v6

I,m playing around with Subara rods and cosworth items currently which all fit ish but only to increase the pin diameter as tempted to go solid lifters and wild cams and maybe 8/9k

Brilliant, thanks! I've ordered a set of 6 conrods, and using the REPEAT10 discount code they came out at around £108 for the set :thumbup:

Subaru rods would be a good idea, the flat 4s can easily spin up to 8000 rpm so the rods should be ideal for solid lifters assuming there are no issues with 'handing' or whatever. Try giving these guys a bell if you need more info / prices on rods - AS Performance (asperformance.com); they're one of the expert posters on Subaru forums and can do specialist engineering work too:

And iirc which i might but as ive measured hundreds of things lately the standard rods use a 9mm bolt and the closet i could find in arp was a set for ford rods fiesta that had the same dimension bolts
and werent to much but would need a set and a half

subaru rods are favourite as currently looking at using a honda bike pistons at 100mm with 23mm wrist pins

Thanks, I'll check out the ARP Fiesta range and see what I can find, though since it's a 12v there's not much chance of me reaching sufficient rpm to need seriously strong bolts :)

The pistons for the 2.5 wrx sti are 99.5-100 mm, 23mm wrist pin and forged are freely available from Mahle, etc so might also be a good fit, and they're 16v quad cam engines so the piston cutouts might not need too much reworking with a bit of luck. Not much chance of finding a decent, cheap set 2nd hand to play with though, any OEM ones which have come out of a dead engine are likely to be in ruins if it was pushing over 350bhp.

Absolutley no need for The holes...
Quite The opposite.
The oil is much better in The Rod bearing than squirting towards piston.

this is the answer i got from another user awaiting reply from Jim himself

Best is 164 super (94-98) 12v block which has already jets.

Again awaiting to hear for Jim

Ah, brilliant, thanks, be great to know the definitive answer :)

I'll have to keep an eye out for a 164 Super block, sounds perfect for my needs.

I,ve a set of 3.0 litre rods here that still have the holes in if you need spares .. a set to lighten etc...

Still awaiting the definative answer
