Uprated Head and Cam.

And so it begins. Well after long awaited anticipation, my car is in the hands of the lincoln green space tuner called DBS. Thanks to Dave for his hospitality and we had a good chat with my friend the Renault 5 Turbo Wizard over the current mods to be installed and future ones. One thing that became clear is after seeing the official specs for the reground cam is that it is very very impressive and done to provide extra torque and BHP in all the right places with minimal effect to idle. I didnt get to see the head as it was having it's final pass of machining but gain the specs for the improvement seem A1 When megasquirt arrives the car should fly especially with my other planned mods I can't wait. I would be interested to see a 480 ES with a reground cam and Head work so come on boys (chris1roll you are our last ES hope......hmm no there is another.......)

<a href="http://www.volvonet.org/tpc/performance ...  Would the adjustable cam gear apply to the B18FT engine?

jamo , thats for the slanty B21 series engines , im thinking of having some made since its a good idea . anyway you can change the timing with some offset ground woodruff keys . Ill need to check , if i have time , to check exactly where the cam is timed , this will be if you can let me have your motor for another week . The cam is ground to be spot on with the original marks , but it would be nice to advance it slightly , that would bring some low end power back . <a href="http://www.dbsmotorsport.co.uk" target="_blank"> <img src="http://homepage.ntlworld.com/mj.slater/DBSsig1.gif" border="0"> </a>

How much would they cost?, i'd imagine you've probably got a manufacture in mind. As for having the car for a second week. I hope you aint clocking my mileage blinging in Lincoln showing of me rims <img src=http://www.ezboard.com/intl/aenglish/im ... /happy.gif ALT=":D"> <img src=http://www.ezboard.com/intl/aenglish/im ... ns/eek.gif ALT=":eek"> <img src=http://www.ezboard.com/intl/aenglish/im ... s/roll.gif ALT=":rollin"> I would probably say it's o.k, lets see how i survive this week on public smegging transport.

sorry , dont do the bling bling thing , but thats nice idea for once its done <img src=http://www.ezboard.com/intl/aenglish/im ... tongue.gif ALT=":p"> i was thinking of just seeing where the cam timing is and contacting my manufacturer to get an offset ground woodruff key (or 2or3) to see the effect that each one has . but the problem is each car is different so it really needs an infintely variable cam wheel that will make up for differences in cylinder head heights etc . that might not get done in a week since i have to design it aswell <a href="http://www.dbsmotorsport.co.uk" target="_blank"> <img src="http://homepage.ntlworld.com/mj.slater/DBSsig1.gif" border="0"> </a>

Yeh but the 480 has an electronic controlled ignition. If you have an offset woodruff key, wouldn't this effect the sparking as it there be a big gap to spark between rotor arm and spark points? I dont understand this one, could you enlighten me?

were talking the small matter of two degrees at the camshaft , the ignition is controlled by a TDC sensor on the flywheel , i think theres more than enough play in the manufacture of the dizzy to allow this . <a href="http://www.dbsmotorsport.co.uk" target="_blank"> <img src="http://homepage.ntlworld.com/mj.slater/DBSsig1.gif" border="0"> </a>

Ah i see, cheers So in the long term are you considering designing a vernier pulley then? and are you going ahead with the woodruff keys?
