MG MGB Technical - K1 Technologies Con Rods
| Hi All, Has anyone had any experience with these new Con Rods. They appear to be significantly cheaper than Carrillo's @ £500 per set rather than £700+ http://www.cambridgemotorsport.com/shop_product.cfm/product_id/9859 Not sure what they weigh in grams as apposed to the carrillo's The above links says they are good for up to 150BHP. That makes me wonder how many BHP the Carrillo's are good for. Does anyone know? A standard set of 18v rods is about £130 a set. Are there any other options between £130 and £500? Thanks Mark. |
| Mark Hester |
| Mark Have you tried www:ridgecrest.com.au in Victoria they make similar conrods to the Carrillo. Have a look at their sight. I have bought t couple of things off them and they were good but not rods. It would be worth an E/mail. |

| Mark, I have been using K1 Technologies rods in my racer and have had 100% reliability. They are the same beam configuration as the Carillo and I know an MGB race expert in America tested the rods bolts for tensil fatigue and found that they were superior than the Carrillo supplied bolts. I think the weight per rod is 590 grams and a stock floating pin rod is about 880grams, but I would have to check if you want exact figures. I think these are brilliant and if you want some for less than £500 (which doesn't include VAT from Cambridge Motorsport) e-mail me because I happen to have 3 sets in my spare room! Joe |

| Hi All I notice the website says finish honed in USA or Designed and finish honed(they make a play on finish hone tolerance)in USA and use ARP fastenings. They don't quite say where the rods are made. I haven't come across anyone using them in the UK. I am not sure what series you race in Joe. Peter |
| peter burgess |
| Hi Guys, Carrillo Rods are 588 Grams, so these are very comparably on weight, also 67% the weight of a standard Rod. Peter, they appear to be manufacture red here: http://www.k1technologies.com/ I've emailed them, but not response. I assume Cambridge has a reasonable margin on them. Joe email me and let me know how much you want for a set please? Many Thanks Mark. |
| Mark Hester |
| Hi Mark I cannot see where it says made in USA, only claims for honing and arp bolts, maybe I am looking but cannot see(typical bloke my wife says). Peter |

| All, The K1 Rods are not made in the USA. They are forged in China and finished honed in the USA, hence the reason that they are so competitively priced. If you want more information it's best to e-mail Tom Molnar direct at K1 Technologies and he will tell you everything you need to know. Peter, Next year I will be competing in the Peter Best Insurance Challenge, as soon as I give you the piston height info so you can finish my head. Sorry for being very slow. Prior to this I did some Peter Best, CSCC Swinging Sixtys and lots and lots of track days. With two hours plus of track time each day I think track days are a great way to test components. Joe |

| Hi Chris, I don't see any refference to MGB's on the: http://www.furiousracingparts.com/products/rods.html Web site. Have you contacted them directly? Also why would the rods need "finished Honed". Cheers Mark. |
| Mark Hester |
| Mark, No there is no reference on the website - they contacted me to try and sell their rods! The website is fairly incomplete but the list I reproduced above is what they sent me. As to the finished honed - either Furious are selling the rods part finished to K1 or K1 are just including wording to give the impression these are US rods? |
| Chris at Octarine Services |
| Hi Chris K1 are not implying the rods are made Stateside they are carefully sayinh waht is done Stateside. As I understand it there is some movement to get Stateside firms to not imply things are being made there when they are not. As far as my sources can tell me the K1 rods have been fine in use to date. I have a concern about the consistancy of the rods, Carillo and other manufacturers tend to have stringent quality controls in place to ensure the ex works product is perfect, K1 rely on the rod maker to ensure quality of metal maybe they check each rod somehow? I use standard used MGB rods in my race engines, they have been tested in use and we measure and inspect each and everyone, then we balance them and prep them for use. Peter |

| Hi Peter, It isn't what they say - it is what they don't say - if they are bought in from China, why not say they are forged there and finished in the US?? What do you use, the 18GG straight rods with small end bush or the very late light ones without balance pads? I used to have the non bushed small ends reamed out and bushes fitted - but the firm that did that for me has got rid of the machine and other local firms want like £40 a rod to do the same! I'd do it on my mill but I can't guarantee the accuracy of squareness without some sort of jig. Is it something you can do? |
| Chris at Octarine Services |
| Hi Chris We are happy to have the pistons press fit, one less thing which may go wrong. We use straightforward common or garden 18v rods. The late small pad rods are very rare. Peter |
| peter burgess |
| They probably don't say they are made in China for exactly the implied (by this thread) idea that all stuff from China is "bad". Sure there's plenty of crap from there, but so there is from other places. No reason a brand new state of the art Chinese plant can't make and QC stuff as well or better than any antiquated US, UK, Polish, or Russian factory. That is one point in favour of some third world stuff - if they never made any before, then their present plants are likely to be far more advanced than stuff in the "established industrialized countries". The "zero-zero" final drive gears for MGA from Hindustan India being a case in point. Some times things are strangely assorted, and you have to look out, both Chinese and Indian things are this way. Threaded holes on the usual cheap Chinese machine tools are awful. I have an Indian made mill vise, which has the most beautifully ground and accurate main surfaces, and the worst fitted small components ever seen - and Whitworth threads! Once I decided that it was a "semi finished casting kit" and redid the small parts, I have an excellent tool for 1/10 the US version. KT(US) may be final honing for this reason, or they may be implying that they are responsible for final QC in the bargain. There's also frequently a language problem, which may apply if KT or whoever is not a native English speaker. It leads to odd omissions and idiomatic errors, even if it's not hilariously funny, as the early Japanese motorcycle manuals were. We used to indulge in various substances and read the Honda books for fun, all wound up rolling on the floor in pain from laughing so much - but it didn't and doesn't mean you can disrespect Honda or their engineering/design/production, as we now know.

| Hi Peter, Interesting - I have wondered about press fitting race pistons - my concern was that there is no flat area around the gudgeon pin boss to take the thrust and I would need to make a curved support. Rare - really? I have two used sets and two sets brand new in the box! |
| Chris at Octarine Services |
| Well Chris, that makes 4 sets, I have only come across 4 or so sets in 25 years. One of those things I suppose, like buses.Thye sets I have had haven't been very close balanced either. We have a special tool for fitting the pistons and pins. Peter |
| peter burgess |
| Pretty well off topic now - but what do you think of the practice of heating the end of the rod to make insertion of the pin easier? I have come across several sets that this has been done to - notably one particular reconditioner's engines... |
| Chris at Octarine Services |
| Hi FR It is keeping the quality up once achieved, as you say once you sorted your vice it was fine. I have no problem with things being made in China as long as the factory desires to make a good product in front of profit as a starting point. Hi Chris There is a difference between warming and blueing :) Peter |
| peter burgess |
| Hehe... some are a bit beyond blueing - the edge is blue, the rest is pure scale! I always warm the piston so the pin drops through easily so it doesn't pick up when being pressed through the rod but I don't bother with warming the rod. As long as the press registers 3 tons I am happy the pin won't shift in service - is your tool the type that uses a torque wrench to measure the pull? |
| Chris at Octarine Services |
| Good to 150 BHP? Damn, and here I was using stock press fit rods for more than that! ;-) There is a lot of crap from China, but also a lot of well machined pieces too. It is discriminating between the two that is the challenge. Sounds like these may be pretty decent rods. I'd wait to hear from someone that has used them in race engines before going for them myself, mind you. |
| Bill Spohn |
| Their sight gives a rating of 150HP "per rod." |
| Denis4 |
| Hi Denis and Bill Rods look good but depends on quality control. That is why I mentioned Carillo, they are very very quality control minded. Chris, we measure the gudgeon pins and little ends and check for problems before fitting. Peter |
| peter burgess |
| Hi, I modify connecting rod with pads by pads suppression, polishing and balancing, a rather big weighty earnings, my machinist put a bush (VPB266) for use with JE pistons and fully floating small end. I use also ARP bolt

| dujuvejd |
| Hi dujuvejd Nice rods, had you thought of shot peening them like the standard ones to increase safety margins after polishing? Peter |
| peter burgess |
| Hi, dujuvejd, it's a data processing mistake, my actual first name is michel. Concerning the shot peening, I thought, but I did not do, yet, I'll do. Thank you. Regards |
| dujuvejd |
| Hi Michel I reckon the dujuvejd is good, it sounds intriguing. Peter |
