smckeown 1 Posted August 24, 2006 QEP are trying their best to get the following done in time for Anglesey on the 17th Sept: New double valve springs Replacement PR inlet valve (current one is slightly bent) Replacement cam, current one is market, so putting a new one i nthere, Matt is recommending a change to 4900343 rather than the current 4900340 to get me some more power top end. Thankfully the piston isn't damaged significantly, just a little scratch i'm told Trying to get a touch up map done at the RR before the track day. Fingers crossed...

Butler 0 Posted August 24, 2006 Great, any thoughts on what when wrong, and will it need a remap? Share this post Link to post Share on other sites
smckeown 1 Posted August 24, 2006 Contrary to previous postings, i'm led to believe the valve spring did indded fail/break Share this post Link to post Share on other sites
Craigb 2 Posted August 24, 2006 340 to 343 , more duration , more lift ! Has Matt indicated what potential increases you will see ? Good luck with it Sean , you need some! Share this post Link to post Share on other sites
smckeown 1 Posted August 24, 2006 (edited) yes i'm due some luck, i was expecting the worse regarding a damaged piston, and them not being available anymore got me worried about a new set of forged items. Thankfully the spring terminally failed at very low revs. SO i'm starting to get a bit of luck No preduction of extra power, but i'll go back with shorter trumpets as per DB's recommendation so we'll see what happens. Let's hope he's right With it making peak power further up the rev range, it would be nice to get the power DB predicted which was ~175 Edited August 24, 2006 by smckeown Share this post Link to post Share on other sites
Jonmurgie 2 Posted August 24, 2006 GREAT news mate, pleased progress is being made and not too much is damaged Looking forward to seeing this one come together again and be mapped! Share this post Link to post Share on other sites

smckeown 1 Posted August 25, 2006 What compression did you plan to run with the 4900343 ? I''m currently running 11.25:1, but am investigating does this need to increase slightly to accomodate the wilder cam. I can't go too far as I have cast pistons. I was thinking nearer to 11.4:1. Can you get gaskets that are in between the mi16 and 205 gti height ? I'm over at QEP later to measure my ignition leads to get some custom magnecor ones made up (I have cheapo temp halfords ones in there currently) so i'll have a chat with Matt Share this post Link to post Share on other sites
Anthony 1,003 Posted August 25, 2006 Hope you do manage to get it sorted in time as it would be good to see the car in action - I'm up at Anglesey along with a few others from here on the 17th as well Share this post Link to post Share on other sites
petert 588 Posted August 26, 2006 (edited) Can you get gaskets that are in between the mi16 and 205 gti height ? What you need is a 1mm copper gasket. Let me know if you want one, I'll put you in contact with the manufacturer. They're approx. AUS$105 + postage. Edited August 26, 2006 by petert Share this post Link to post Share on other sites
phatgti 0 Posted August 26, 2006 The race regs stated that i couldnt go more than 2 points higher than standard meaning 11.6:1. Reasonable easy to get with Mi16 pistons and a good skim. Share this post Link to post Share on other sites
smckeown 1 Posted August 26, 2006 (edited) Here are some pics of the damage... 3 piece valve spring anyone ? Marked piston: PeterT - I'll discuss that gasket option with QEP, cheers. I did do some research on here earlier anhd Matt was quoted as saying he thinks the copper gaskets are old school compared with composite ones. I'll speak with him soon Edited August 26, 2006 by smckeown Share this post Link to post Share on other sites
petert 588 Posted August 26, 2006 not sure about being old school. They're a cheap and easy way to fix CR and squish height problems, especially on wet liner engines. The liner protusion really digs into the copper, reducing the necessity for o-ringing. Share this post Link to post Share on other sites
smckeown 1 Posted August 26, 2006 ok thanks peter, i'll certainly discuss it with QEP ASAP Share this post Link to post Share on other sites
Alex G 0 Posted August 28, 2006 The liner protusion really digs into the copper, reducing the necessity for o-ringing. oh thats nice to know, i was worried it would stop it sealing as well, esp around the water and oil ways! Sean, would you let us know what you decide on gaskets after speaking to QEP, Cheers Alex. Share this post Link to post Share on other sites

Hi Peter, I've read and read and I still can't get a good (read simple) explanation regarding the benefits of copper head gaskets vs. normal ones. Care to expand ?
