Se7en Posted February 27, 2011 Share Posted February 27, 2011 Quoting Mad Hatter: *arrowup*Thank you I was joking about the Rotrex though, with the power curve being so smooth it should be great for getting the power down which might be compromised if i switch to forced induction I need a rest from it too, this upgrading lark takes it out of you Time to get back to some driving, then plan stage 2 How is yours going ? Projects like this are tough, especially if you are physically doing the build as well as planning and sourcing all the parts. Mine has had a few mods over the winter - some improved SC mounts, heat shields, better air filter location and cold air supply, shift lights, custom tonneau, etc. The big problem on our initial running was fuel pressure - I think this is down to needing a relay to power the pump properly. We will see. Also had the silencer re-packed and some reverse cones shoved up my exhaust Link to comment Share on other sites More sharing options...

Racing Snake Posted May 27, 2011 Author Share Posted May 27, 2011 Failed valve spring Damaged follower Broken and bent intake valve Bent exhaust valve Dented piston Slight damage to head and valve seat Spring being sent away for testing Damage minimal considering it went at 6500 rpm Bloody strong pstons too as it punched the valve into the port Should all be sorted in a couple of weeks Link to comment Share on other sites More sharing options...
Area Representative Nick Chan Posted May 27, 2011 Area Representative Share Posted May 27, 2011 Carl, Glad to hear it sounds minimal and relatively easy to sort considering the picture of the valve you sent out! Nick Link to comment Share on other sites More sharing options...

Racing Snake Posted August 3, 2011 Author Share Posted August 3, 2011 Thats it the Duratec is back in the back of the van with a whole raft of redesigned and upgraded parts. Valve lift has been reduced by 0.5mm and the inlet cam is a new design Replaced all the valve springs with a new duplex type Replaced bent valves Replaced all pistons with a new improved set Compression has been increased New cam chain Etc A big Thank You has to go out to Simon Armstrong at Ultimate Performance for sorting out the engine after a spring failure at the Isle Of Man He stripped, assessed, repaired, redesigned and rebuilt the motor without a quibble,a true professional If you want an engine built or any cylinder head work done Simon is the guy to speak to Cant wait to get it back in the YOB Link to comment Share on other sites More sharing options...
