V7 SLR Posted December 7, 2004 Share Posted December 7, 2004 ... read this. The article is from Racecar Engineering, this month. Written by Simon Erland. This article ought to start a fire amongst the non-K'sters Link to comment Share on other sites More sharing options...
Peter T Posted December 7, 2004 Share Posted December 7, 2004 Yes it was a good article, still can't see it being one of the best engines ever built, yes first for a production line, but to blame engine tuners/ builders on the unrelaibilty issues is a bit strong. And then Rover saying that no one approched them for advice on this engine, b*ll*x more like they did not want to share the information if any ?????? Support the 7 Society...... Ehhh?

neil.cavanagh Posted December 7, 2004 Share Posted December 7, 2004 the balancing figures on the cranks and flywheels are very interesting... if these after market ones are really so bad (10x worse than standard OEM) then I could see that reliablilty could be affected..

Mike Bees Posted December 7, 2004 Share Posted December 7, 2004 Take some of the balancing figures with a pinch of salt. Especially the 19.7 gmm at the nose of a K-series crank. The location of the damper pulley is so poor that just unbolting it and bolting it back on can give 40 gmm difference in the unbalance measured.

Joe 90 Posted December 7, 2004 Share Posted December 7, 2004 A 250BHP duratec should give a respectable bhp/kg SEP field working, not spotted in 103,000 miles. Some photos on webshots, updated 21 Sept Link to comment Share on other sites More sharing options...
Peter T Posted December 7, 2004 Share Posted December 7, 2004 Yes i found that interesting too, but did they just get a supplied crank and not balance it then? I would have thought that you have a crank balanced with pulley and flywheel, and that is why the figures seem very far out, where the standard crank is balanced in harmany with all components fitted. I.ve had brand new rods that have to be ligtened by many grams cos the pistons are differant weights. Support the 7 Society...... Ehhh? Link to comment Share on other sites More sharing options...
Mick Day Posted December 7, 2004 Share Posted December 7, 2004 An interesting article indeed. As someone with a vested interest in the "K", as in I have one in my 7, I'm a little biased. Who is Simon Erland? Three people of interest, amongst others, who are mentioned in the article are Dave Andrews, Peter Carmichael & Roger King: would they like to comment?

Gary Drew Posted December 7, 2004 Share Posted December 7, 2004 It's poor 'journalism' whoever he is (IMHO), tho not quite as poor as the pure gibberish written about developments in rotary valves a couple of issues ago...

Nick Green Posted December 7, 2004 Share Posted December 7, 2004 For the record, the article in Racecar Engineering is a much editted down version of the article available from V7's link. Link to comment Share on other sites More sharing options...
V7 SLR Posted December 7, 2004 Author Share Posted December 7, 2004 Yeah, I've now received a scan of the Racecar article. It almost reads like a different article in places. It's 1Mb PDF file. Anyone inerested if I stick it up on the net somewhere? Link to comment Share on other sites More sharing options...
Graham Perry Posted December 7, 2004 Share Posted December 7, 2004 So how many seveners have fitted the newer pressure sensitive thermostat to their K's then ? There will probably be a rush now. Link to comment Share on other sites More sharing options...
Mick Day Posted December 7, 2004 Share Posted December 7, 2004 V7 I'd like to read the full article. Mick Link to comment Share on other sites More sharing options...
Nick Green Posted December 7, 2004 Share Posted December 7, 2004 Mick, I'd say the article linked to at the top of this thread is the full article. BTW, the article at the top makes references to the magazine in which it is published. Which magazine is this ? Does anybody know ? There is no mention of publication date either.

Peter T Posted December 7, 2004 Share Posted December 7, 2004 It is published in Racecar Engineering, January edition 2005. I have a copy in front of me, i think you can only subscribe to it, as i have never seen a copy on the shelf at smiths. See www.racecar-engineering.com for details. Support the 7 Society...... Ehhh?

V7 SLR Posted December 7, 2004 Author Share Posted December 7, 2004 I've just noticed that one page is repeated at the expense of another. Wait a while and I'll try to get a proper copy up. Link to comment Share on other sites More sharing options...

RESOLVIWOLF Posted December 7, 2004 Share Posted December 7, 2004 hmmm been through all this long ago on exiges.com and seloc and its already been well established by people in the know (and K experts) that this is nothing more than the delusional ramblings of someone who clearly has adopted a very peculiar defensive position with reagrd to the mighty K.

V7 SLR Posted December 7, 2004 Author Share Posted December 7, 2004 Mmm... polarised opinions. Don't you see the irony in your posting that Jackal? 😬 Link to comment Share on other sites More sharing options...
Peter Carmichael Posted December 8, 2004 Share Posted December 8, 2004 For once I am in agreement with Jackal. This article is renowned gash. I'm flattered that my old 250 bhp engine gets mentioned, but the reasoning is flawed and the arguments are somewhat adductive. The author tells a good story, but it is not necessarily based on reality. Link to comment Share on other sites More sharing options...
AMMO Posted December 8, 2004 Share Posted December 8, 2004 Didn't like to say that myself Peter. Its much better coming from you. Don't wan't to get a reputation for being biased towards another brand of engine 😬 AMMO Link to comment Share on other sites More sharing options...
