Bartman Posted September 30, 2021 Share Posted September 30, 2021 Ordered back in June my new Raceline Zetec is finished and going on the dyno tomorrow, the Sadev box arrived from France today too. Here is the new beating here is the soon to be beating heart of my 7 Cant wait to get it up and running. Bart. Link to comment Share on other sites More sharing options...
Kitcat Posted September 30, 2021 Share Posted September 30, 2021 Looks pretty awesome! I have spent a lot of time looking at their tempting Zetec line up. The other nearby engines suggest it’s still with Raceline in Great Britain? Link to comment Share on other sites More sharing options...
S1Steve Posted September 30, 2021 Share Posted September 30, 2021 Appreciate your good taste in cam covers, I always like the BDA style. And the Sadve is a excellent bit also.. Enjoy…🍺 Link to comment Share on other sites More sharing options...
Bartman Posted October 1, 2021 Author Share Posted October 1, 2021 Yes It’s still in the UK. Peter and Chris have been amazing and patient. I’ll post the dyno when I get it. I’m pretty interested to see how the numbers come out. I hope this will be stateside by November. Link to comment Share on other sites More sharing options...
Bartman Posted October 6, 2021 Author Share Posted October 6, 2021 Got word from Chris at Raceline that the first Dyno yielded close to 260 HP using the Dyno Exhaust, they are going to run it again with my exhaust tomorrow and smooth out the mapping a bit then it's on its way. I don't have the trace yet but will post that when I get it. Bart NLFB9182.MOV Link to comment Share on other sites More sharing options...

Bartman Posted October 7, 2021 Author Share Posted October 7, 2021 Just remembered that the Head work was done by Simon Armstrong's Ultimate Performance business in the UK https://www.ultimatep.com/about/ Bart Link to comment Share on other sites More sharing options...
Kitcat Posted October 7, 2021 Share Posted October 7, 2021 What is redline (7800rpms?)? What is the octane required? Combined with the Sadev and paddle shifters this should be formidable at the track. Link to comment Share on other sites More sharing options...
Bartman Posted October 7, 2021 Author Share Posted October 7, 2021 They told me redline at 8200 but I will scale that back, not sure what I'll limit it to yet, I need to see the actual dyno trace using my exhaust to see what makes sense. It was run up using UK 98 RON (US 93 POM), I also had them fit a knock sensor and upgraded to wide band Lambda (from SBD) so should be good and work out well using the MBE9A9 - (not that I know enough about this to be sure ) Link to comment Share on other sites More sharing options...
JohnCh Posted October 7, 2021 Share Posted October 7, 2021 Really impressive results. I'm curious to see how the exhaust change affects the shape and height of the torque curve. Did they share the specs of the dyno exhaust so you know how it differs from the one you will use? -John Link to comment Share on other sites More sharing options...
BlueBDA Posted October 7, 2021 Share Posted October 7, 2021 Really nice. One question that I am curious about, as I don't know a ton about these engines: What is the advantage of building a Zetec like this vs doing the same with a Duratec? Link to comment Share on other sites More sharing options...
Bartman Posted October 7, 2021 Author Share Posted October 7, 2021 Chris did not share the spec of the Dyno exhaust, but, they are going to re-run the Dyno with my actual exhaust on it as they are supplying the complete end to end exhaust as part of their package. So in the end, I should have both traces and be able to make that comparison. Chris believes we will see a slight drop in the figures from the initial run but still be making mid 250's I'll post both when I have them for anyone that is interested. I am curious myself, and to understand what sort of parasitic loss I will get from crank to wheels, I read somewhere its +/-18% but have no clue. Not that it matters as it is what it is, but still curious. Bart. Link to comment Share on other sites More sharing options...
Bartman Posted October 7, 2021 Author Share Posted October 7, 2021 BlueBDA, I would have "preferred" to go the Duratec route (lighter and more choices available 2.3 2.5 etc.) but the induction and exhaust on the Duratec is opposite to the Zetec and the car already has a Zetec in it, I did not want to go though the hassle of changing panels, engine mounts and all the other routing of pipes etc that would have been needed to go to a Duratec so decided to stick with the older Zetec design.

Not that it matters as it is what it is, but still curious. 15-20% is the range bandied about on the Internet, but there are simply too many variables to have an accurate, universal number. Different dyno types and brands, different correction factors on the same dyno model, different rolling resistance of tires based on rubber compound, carcass construction, and air pressure, how tightly the straps are pulling the tires down against the rollers, the car itself (longitudinal vs transverse engine, transaxle vs. transmission + diff) etc. My primary dyno facility has a lot of experience running the same engine on an engine dyno followed by installing it in the car then running on their old Dynojet. They typically see a 15-18% loss depending on variables, and said a car like ours is generally at the top end of that range. But again, that number is specific to their dyno and is subject to error. Interestingly, dyno shops in the UK generally perform a coast down measurement to account for most of the systemic losses above and produce a corrected, at the flywheel number specific to that dyno session. However, in the US that methodology is generally considered flawed and is rarely used. Apparently the preferred temperature of our beer isn't the only head scratching difference between our two cultures. As for Duratec vs. Zetec, I agree with you 100%. Yes, a Duratec has more power potential and is lighter, but the Zetec can clearly produce a lot of reliable horsepower and isn't exactly a boat anchor. If you already have a Zetec, I'm not sure the conversion hassles outweigh the gains. -John Link to comment Share on other sites More sharing options...
Bartman Posted October 7, 2021 Author Share Posted October 7, 2021 Interesting about the Dyno I had no idea there was a difference. Even after nearly 20 years gone from the UK I still hanker for a warm pint of Theakstons Old Peculiar but I am heading to London tomorrow so that's on my agenda for sure : ) I did look long and hard at the Raceline Duratec 300hp spec, it was in the same order of cost but then I also figured I'd have enough horsepower to scare myself silly with 250, so the hassle factor won out. With luck I will have all the pieces and parts here in the US around thanksgiving and have the whole thing back on the ground in a month or two thereafter. The list of things to do is rather long but will be a lot of fun to work on, the last pieces of the puzzle are getting the roll cage which is on order and coming over in a container during November and finalizing what to do about the brakes, it currently has the out of the box standard Caterham circa 2005 setup, I am still trying to figure that part out.

Bartman Posted October 22, 2021 Author Share Posted October 22, 2021 As mentioned earlier they re-ran a dyno on my new Zetec using the exhaust that will be used on the car. There is still some work to do on the mapping when it gets here, but the early results look pretty promising.

fastg Posted October 22, 2021 Share Posted October 22, 2021 Looks great, that's a big torque spike between 4800-5500, should be fun. I owned a DYNOmite morotcycle dyno, in fact I still have the absorber and control unit. Thinking about building an engine dyno one day.
