Ahmotorsport Posted May 31, 2012 Author Share Posted May 31, 2012 sorry for the q&a session lol, so when your done what sort of hp and torque figures are you expecting?No problem, ask away. This spec will be around 200BHP, not sure on torque, but thats what we're after. Link to comment Share on other sites More sharing options...
Ahmotorsport Posted June 2, 2012 Author Share Posted June 2, 2012 Update time. Head's back from the machine shop, had to machine the valve spring area so the cam lobes could rotate without hitting the head. Ground the valves in, got everything ready to check the spring heights and did that all important 20BHP mod. http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000695.jpgCleaned http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000696.jpgMachined away http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000697.jpgPainted http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000707.jpgPainted http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000698.jpgPainted http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000697.jpgPainted http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000699.jpg http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000700.jpg http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000701.jpgValve spring platforms http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000702.jpgValve spring platforms and shims http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000704.jpgValve springs and vernier pulleys http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000705.jpgGround in valve http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000706.jpgModified spring tops Onto that all important upgrade.... http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000712.jpg http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000714.jpg http://i958.photobucket.com/albums/ae68/Ahmotorsport/WP_000716.jpg Link to comment Share on other sites More sharing options...

DaweV6 Posted June 3, 2012 Share Posted June 3, 2012 I'm surprised you're using aluminium pulleys?Why's that? Because old fashioned steel ones are better ? I'm surprised you are using single springs. What will be the RPM limiter set to ? And 200 BHP ? What's the total budget ? We have a 1700 rally engine with 183.9 BHP, so I'm very interested to see what you gonna do with this one. How much are you pitting the pistons ? Link to comment Share on other sites More sharing options...
Naylor2006 Posted June 3, 2012 Share Posted June 3, 2012 So this engine started life as a bog standard 1.6 Zetec like the one you'd find in an Escort? Or is it one of those backwards ones you get in the fiestas? Link to comment Share on other sites More sharing options...
supersport Posted June 3, 2012 Share Posted June 3, 2012 it's a focus/fiesta engine. Link to comment Share on other sites More sharing options...

He said in his first post that he reckons it could do 8500 however it would be down to the owner of the engine to set the limiter. Link to comment Share on other sites More sharing options...
Ahmotorsport Posted June 3, 2012 Author Share Posted June 3, 2012 200BHP is quite achievable in a 1.6. My Pa reckons with the right amount of money he could do a near on 250BHP version, but that'll be expensive. Inlet at the front Fiesta engine. The springs have proved successful over the many years on another engine we've developed. Why are the old fashioned steel ones better? They've heavier for a start? There is nothing wrong with aluminium verniers, again, we've used them for years. The budget is what the guy bought, he asked us to do the best we could with the parts he gives us. 200BHP is the ball park figure, it also depends on mapping, when we mapped the Focus we messed around with cam settings etc for ages to get his phenomenal torque curve. Whether the owner will do that i don't know, he may ask us to map it as well yet, i don't know. Pitting? As in valve cut outs? We've cut them to give enough clearance.

Stu Posted June 3, 2012 Share Posted June 3, 2012 I'm surprised you're using aluminium pulleys?Why's that? Because aluminium pulleys wear and throw the timing out. Good luck with getting a genuine 200bhp. Ford motorsport got this engine to about 205bhp with lots of development, and that was on a far superior inlet.

Bear in mind they only do a few thousand miles a year. Ford also said you can only have 250BHP from a Zetec, im not saying they're wrong or anything.

Stu Posted June 3, 2012 Share Posted June 3, 2012 Ford also said you can only have 250BHP from a Zetec, im not saying they're wrong or anything. I highly doubt they ever said that. Of course there are a lot of people working at Ford, so perhaps a janitor or something may have said something about his station! Link to comment Share on other sites More sharing options...
