EFA Posted January 19, 2007 Share Posted January 19, 2007 No Anotella, The 1/4 mile stuff is kind of hard to misrepresent. The results on the 1/4 mile strip, especially same venue/same day stuff such as this, are the performance gospel. Emma, the post implies I was running with a +2.0sec h/c. i.e with only 40bhp more I actually did a time 2.13 secs quicker. There's lots of history when Norman's involved. But he wishes to keep it that way. EFA - Ex Fat Arnie 4 Counties AO and owner of K2RUM The car of two halves which is very nearly back on the road.

AMMO Posted January 19, 2007 Share Posted January 19, 2007 Arnie Sod off. This is a post about Duratecs and the mental state of the engine buying public. Don't you dare bring something as trivial s bloody drag racing into it! 😬 Don't know what you are talking about anyway as I have never been to a drag race and real motorsport has bends in it (or dynos). Brent I've posted this before. Here we go again: “It is unwise to pay too much… but it is worse to pay too little. When you pay too much, you lose a little money…that is all. When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing it was bought to do. The common law of business balance prohibits paying a little and getting a lot. It can’t be done. If you deal with the lowest bidder, it is well to add something for the risk you run. And if you do that, you will have enough to pay for something better”. John Ruskin Then there is the modern-day condensed version courtesy of a friend, Carlos Paul, who hails from “The House of the Mouse” (Orlando, Florida). “You can’t make chicken salad out of chicken s**t”.

Wile7 Posted January 20, 2007 Share Posted January 20, 2007 When I go back to Blighty with work in September I am interested in having Wile toyed with. It has the crossflow currently. I've also had a K series before. Arnie got me thinking when he posted a comment about that nice white hpc with clams some months ago. Now I see that offer about the Duratec in LF..... But I also want to see lakeys Toyota powered unit and I fancy a Jap option - Honda or Nissan or indeed the boxer from Subaru....could it be done? Who knows, but there are many possibilities I think. The bike engined options are too wild for a wimp like me Will continue to research........otherwise Duratec it is I think (cheaper than xflow rebuild to get similar reliable power). I only want a fast road car, not a track day special... Link to comment Share on other sites More sharing options...
I.Mupferit Posted January 20, 2007 Share Posted January 20, 2007 Having been designed by Mazda, the Duratec is kind of Japanese by association so to speak. I should think a sweet 2L Duratec would fit the bill for you quite nicely. Brent 2.3 DURATEC SV Reassuringly Expensive R 417.39 😬 Link to comment Share on other sites More sharing options...
AMMO Posted January 20, 2007 Share Posted January 20, 2007 Graham Stock head is around 130 cfm. Modified from 140 to 158 cfm depending on power requirement. Big valve heads up to 175 cfm. All testing is done at 25" on a Superflow 600 and converted to 10" which is what most people quote. 175 cfm at 25" is 276.5 cfm. Maybe I should quote the higher figures. It sounds more impressive 😬 Chris Fitted the head to your engine and shimmed the cams this morning. Just need to do the cam timing on Monday and close it up so I can get cracking on Danny's. Still trying to convince Dave Walker to finish his Superflow 901 engine brake so we don't have to install the engine in a car to map it. Looking forward to seeing what it makes. I have a feeling it will be very nice indeed. 😬 AMMO Link to comment Share on other sites More sharing options...
Jason Plato Posted January 20, 2007 Share Posted January 20, 2007 slipped my 2L duratec into the engine bay this morning it sits well back in the chassis with the short titan bellhousing . Gotta load him up on the trailer tomorrow to go and get the loom made ,then we can "dress" the engine Wiley - I think the offer in LF is for the zetec conversion not the duratec. here is C7 TOP Taffia Area Rep Link to comment Share on other sites More sharing options...
rgrigsby Posted January 20, 2007 Share Posted January 20, 2007 As a current RaceCo Duratec owner I really should stop reading this thread, all this talk of new cranks, big valve heads etc etc it's bound to be bad for the bank balance 😬 note to self: I'm completly happy with 260ish bhp 😬 Rob G www.SpeedySeven.com Link to comment Share on other sites More sharing options...

Tony Abbatiello Posted January 22, 2007 Share Posted January 22, 2007 Interesting thread Most of the power figures seem to come from the 2.3 Duratec, has anyone every done a full on 2.0l engine? Apparently it has a shorter stroke so it should be a revvy engine rather than producing large amounts of mid range torque. I run a 2.0l BDG on carbs and I was wondering what a direct comparison would be. Can't wait to see Dave J at the sprints to see what he makes of the Duratec compared to his big K.

simonbell Posted January 22, 2007 Share Posted January 22, 2007 Mountune use to advertise a 280bhp 2.0l duratec.........not sure if anyone has one though.

AMMO Posted January 22, 2007 Share Posted January 22, 2007 Simon I'm also going for around 250/260 bhp with my next 2 litre. Need to drive it to the shops, go on my hols etc. so not going too crazy. Thanks for telling Rob he needs an upgrade 😬 Just a little tweak here and there Rob. MikeE 2.3s are getting a bit thin on the ground. None in stock at the moment but I'm sure I can dig one out for you if you are interested. Graham They are bloody good figures. What do you think I've been going on about for the last five years! I have not seen a better production cylinder head. End of story. Not perfect by any stretch of the imagination but good enough. Can be improved a lot from stock. Chris Cams timed in today. 😬 Tony Whatever you can get out of a 2.3, you can more or less get out of a 2 litre. Rpm and torque change. On the whole the 2.3 is a bit easier but it cannot rev as much. I too am waiting to see what Dave Jackson gets up to. The man can definitely pedal a car from what I've heard. It probably wouldn't matter what he drove but it's nice to think he made a sensible decision regarding engines. 😬 AMMO Link to comment Share on other sites More sharing options...
simonbell Posted January 22, 2007 Share Posted January 22, 2007 Ammo 250-260 is a nice levele for getting 500bhp per tonne........I`m hoping to get around 260 from the engine so that I don`t have to buy quite so much carbon.......I reckon I need to loose about 20kg`s aith 260bhp to achieve the 500 figure with a full tank of fuel. I should take possession of the head I`ve bought this week at some point.......It`s fitted with Piper 300 cams......which sound a bit aggressive but when you look at the spec they aren`t as bad as I first thought, still not convinced so may swap them for 285`s...........then again I might just go for it and see what they are like 😬 I`m going to need rods and pistons for this one, probably the uprated fuel pump, bigger injectors........and I need to sort out the exhaust as well. How far can I go with the Raceline 45mm DTHTB`s......will they be OK to 260bhp?

Dobuy Posted January 22, 2007 Share Posted January 22, 2007 Ammo Chris, Cams timed in today Jeez, I thought I was the only one to take a whole day to degree in Cams Simon, I had lots of interesting conversations at the Autosport show about upgrading my 45mm Jenvey's to something more vacuous. The perceived wisdom was, don't bother, they are good for about 260-270bhp and I was unlikely t see more than a few bhp improvement with the more exotic choices. In fact one chap whose opinion I value reckoned he was going back to normal TB's after his ventures with roller barrels.

I.Mupferit Posted January 22, 2007 Share Posted January 22, 2007 Ammo, so why are the 2.3's getting thin on the ground, have Ford ceased production of them already? Just when I thought I had an engine and car that were still in current production. ☹️ Brent 2.3 DURATEC SV Reassuringly Expensive R 417.39 😬 Link to comment Share on other sites More sharing options...
AMMO Posted January 22, 2007 Share Posted January 22, 2007 Neil You know, get up at 10. Shower, shave, black coffee that I have exclusively imported from my contacts in Colombia. Personal trainer comes around to discuss new diet and training regime. Have another coffee, shoot the breeze for a couple of hours. Lunch with friends, something informal, had a chef come around so we could eat at home. Friends leave. Have a nap. Wake up, shower change into my work clothes (ugh!). Nip into work for ten minutes. Time in cams, go home. Waiting for limo to come and pick me up for all night partying with a couple of supermodel friends. Tomorrow I might put the cam cover on if I can face the awful working conditions. AMMO Link to comment Share on other sites More sharing options...
simonbell Posted January 22, 2007 Share Posted January 22, 2007 Thanks for info re throttle bodies, I was hoping someone would say that the 45mm versions would be fine to 260. I don`t like the roller barrels so if I had needed to change it would have been for a larger version of the ones I have now.

Tony Abbatiello Posted January 22, 2007 Share Posted January 22, 2007 Thanks for the info. 260bhp for something flexible and reliable seems very good, what rough cost is this kind of spec, are we talking £5k or £10k? Link to comment Share on other sites More sharing options...
