Chris Wilson Posted June 29, 2009 Share Posted June 29, 2009 Just ordered a set of new valve springs for the Mugen in my Lola. This is one bill Jane's definitely not seeing..... Quote Link to comment Share on other sites More sharing options...

SUPRALOOPY Posted June 29, 2009 Share Posted June 29, 2009 £23 + Vat you tight arse!! LOL Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 29, 2009 Author Share Posted June 29, 2009 1900 plus VAT, plus carriage and import duty from Japan. If I have the heads machined to use Cosworth DFR springs it'll probably end up dearer still..... It's cheaper to have valves and top hats made than buy from Mugen. Some of the prices are frankly terrible. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 29, 2009 Share Posted June 29, 2009 How much??!! Knocks my £268 quid for VSVs into a cocked hat lol Quote Link to comment Share on other sites More sharing options...
Homer Posted June 29, 2009 Share Posted June 29, 2009 My God I was going to suggest £1k, but well over £2k is insane. Are all the other parts on that engine going be of similar cost? Best not blow it up I guess Quote Link to comment Share on other sites More sharing options...

Guest Budz86 Posted June 29, 2009 Share Posted June 29, 2009 How the hell can they warrant charging that much! It's only a few tiny piece's of metal! Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 29, 2009 Author Share Posted June 29, 2009 It was a £50K plus engine in period (early 90's), sadly parts prices still reflect that. It's having steel rods, the Ti rods in it now are £550 a piece...It's a bit down on the leak test, and it's mileage history is patchy, I'd rather freshen it now than wait to see what happens Quote Link to comment Share on other sites More sharing options...

Is it because they only made a small number and so the R&D costs are shared between a smaller pool of purchasers? (I know nothing about these, just curious. ) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 30, 2009 Author Share Posted June 30, 2009 The MF-308 was Mugens answer to the all conquering Cosworth DFV F1 engine. It was lighter, with less internal friction, a bit smaller, and with the potential for better valve opening due to finger follower design. The original was made by Judd, as the BV, and then licensed to Honda Mugen, who developed it a bit further. They also made a 3.4 version, and now have a fairly similar 4 litre racing sports car engine using the same architecture. The springs have a 10 hour life, are x-rayed as standard, and are made from the best material possible in ideal conditions, in very small relative quantities. At least that's what I keep telling myself when I open my cheque book Quote Link to comment Share on other sites More sharing options...
AlexM Posted June 30, 2009 Share Posted June 30, 2009 £218.50/hr just on springs, that's some running cost. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 30, 2009 Author Share Posted June 30, 2009 Don't put it like that, it's *so* negative 500 BHP in under 600 kilos makes it worth it though Some people risk running well over the recommended hours, I am sure this engine has near double them, but the thought of it throwing a rod is daunting.

SteveR Posted June 30, 2009 Share Posted June 30, 2009 10 hour life. owch. I suppose they are the result of engineering something to work to within the finest tolerances for a 'reasonable' amount of time for motor racing purposes, and without too much consideration for the resulting cost. Still - owch, owch, owch. Can you somewhoe measure/quantify the performance of the new ones before they go in, and the old ones as they come out? Would you expect to see any degredation Chris, or would they work perfectly right up to the point of catastophic failure? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 30, 2009 Author Share Posted June 30, 2009 They will probably show some loss of free length, and some loss of rate at compressed height "X". Fatigue is the killer though. Quote Link to comment Share on other sites More sharing options...
