TriumphV8 Posted June 14, 2018 Report Share Posted June 14, 2018 Very competitive pricing compared to others. Honestly said I ended in the range from 1000 to 1500 Euros making my own system including soldering the MegaSquirt together. But keep in mind that only a really good set of manifolds with the spindles fully free of play and a proper setting can bring all the benefits of modern EFI fully to work! Also I would expect that some smaller parts like EARLs connectors and weatherproof electrical connectors might boost the price a little bit. Keep us informed about the progress.

john.r.davies Posted June 14, 2018 Report Share Posted June 14, 2018 Nearest to a TR6 on their site is a converted Vitesse. https://www.classicfuelinjection.co.uk/images/classicfuelinjection%20-%20triumphvitesse4.jpg Ask for contact details of the owner? JOhn Quote Link to post Share on other sites
Tr4Deano Posted June 14, 2018 Report Share Posted June 14, 2018 Expensive but if going EFI would go for the Jenvy fuel injected Webber copies Quote Link to post Share on other sites
JohnRoberts Posted June 14, 2018 Author Report Share Posted June 14, 2018 Hi Guys Thanks for the replies so far. I was thinking of using my existing throttle bodies, refurbished. Regards JohnR Quote Link to post Share on other sites
Tom Fremont Posted June 14, 2018 Report Share Posted June 14, 2018 Good luck with the conversion, John. Wonder what you're hoping/expecting to gain...if it's reliability you'll do very well to match Webers. Cheers, Tom Quote Link to post Share on other sites
marki Posted June 14, 2018 Report Share Posted June 14, 2018 Hi John. I went with a company called Emerald, very helpful in all aspects of the conversion. The difference is remarkable. Good luck, you won't regret it, Mark. Quote Link to post Share on other sites
JohnRoberts Posted June 14, 2018 Author Report Share Posted June 14, 2018 Hi Marki That looks a superb conversion. I like the Metalwork push in pneumatic fittings, used to sell them in my dim and distant working days. Regards JohnR Quote Link to post Share on other sites
stuart Posted June 15, 2018 Report Share Posted June 15, 2018 Hi Marki That looks a superb conversion. I like the Metalwork push in pneumatic fittings, used to sell them in my dim and distant working days. Regards JohnR Whats the purpose of them on that installation? Stuart.

michaeldavis39 Posted June 15, 2018 Report Share Posted June 15, 2018 (edited) Marki could you explain the remarkable difference please in a bit more detail as am on the cusp of deciding which way to go with my own engine restoration- had Zenith's on and have acquired and refurbed all necessary components to make it PI just got all plumbing to sort out.

TRTOM2498PI Posted June 15, 2018 Report Share Posted June 15, 2018 Hi Michael, I have the same installation as Marki. Prior to this, I had a rebuilt Lucas PI system, on a modified engine. The most noticeable difference is fuel economy, which will see approx an extra 100 miles to a full tank. Smoother through the rev range, and longevity of engine oil, as it now longer receives the petrol mix down the bores. Throttle response is instantaneous, too. Cheers.

michaeldavis39 Posted June 15, 2018 Report Share Posted June 15, 2018 How do you mean it no longer receives the petrol mix down the bores- have you got the Jenvey throttle bodies or kept original Lucas ones? Quote Link to post Share on other sites
TriumphV8 Posted June 15, 2018 Report Share Posted June 15, 2018 Whats the purpose of them on that installation? Stuart. I would expect its only collecting the vaccuum lines for metering purpose. It is always a bit nasty to get rid of the pulsations in the vaccuum to receive a clear information for metering. Quote Link to post Share on other sites
TriumphV8 Posted June 15, 2018 Report Share Posted June 15, 2018 The difference to carbs is +15HP for free but also for PI there is some difference. 1.) PI does not see the rpm signal. Metering full load at 2000 rpm is the same as at 5500 rpm per revolution. Unfortunately the engine can not digest the perfect metering amount at 5500 if you have lower revs. Either you have to set it for 2000 and lean at 5500 or set at 5500 and overrich at 2000. 2.) PI does not recognize different air temperature but warm air contains significantly less oxygen per litre. 3.) PI does not recognize different air pressure that will happen on higher altitude but also under different weather conditions. 4.) EFI can control itself with a AFR wideband sensor. 5.) EFI can set itself and learn with the wideband sensor. 6.) EFI can be set lean in some areas for cruising and can be set rich for best performance in other areas. They can be defined and found very easy. 7.) Cold start can be programmed to perform automatically. 8.) EFI has an acceleration enrichment to avoid leaning when pressing the pedal. also it has a leaning function under deceleration to save fuel and get better emissions. 9.) It has a fuel cut of for maximum engine braking and fuel economy. 10.) It can drive the ignition if required and can be set more detailed and much better than the 123tune for example. To be continued........ Quote Link to post Share on other sites
marki Posted June 15, 2018 Report Share Posted June 15, 2018 Hi All. I presume the debate is about the six nylon pipes from a manifold, these are for the idle air. Basicly the throttle bodies are fully shut at no throttle and the air intake s controlled by an idle air valve this controls cold start as well. As Tom has described already fuel consumption response drivability and for me a big bonus is reliability as I didn't get on with MR Lucas. Idle air control valve is on the left. Cheers Mark.

DRD Posted June 17, 2018 Report Share Posted June 17, 2018 Hi Guys Does anybody have any experience of the kits supplied by this co. called Classic Car Injection.co.uk I am considering converting my 1972 CP/PI Best Regards JohnR This looks great, any idea on cost? Is it a DIY job? Quote Link to post Share on other sites
JohnRoberts Posted June 17, 2018 Author Report Share Posted June 17, 2018 Hi DRD Their web site gives the price of £1450 complete. To fitted by anybody capable with spanners. Regards JohnR Quote Link to post Share on other sites
DRD Posted June 18, 2018 Report Share Posted June 18, 2018 Thanks John I'm tempted! I spotted that they've got one on TR4. Quote Link to post Share on other sites
harrytr5 Posted June 19, 2018 Report Share Posted June 19, 2018 If you look up past contributors on this subject you should be able to gauge if you want to go that route. I did mine around 2011 using the original throttle bodies with the butterflies removed and a single throttle body on the air plenum. Emerald supplied the rest and a brilliant company to work with. I am biased of course but the very best mod of the many I have done to my TR5. Remember it is now a modern set up and if it goes wrong a breakdown truck will have to collect it.Although if you carry a lap top and have a wifi signal Emerald might be able to diagnose over the phone.

Can not agree to that. Looking at Megasquirt inside is the chip for modern ABS systems, millions are in use, very few fale. Would be very dangerous if it does! Also modern electronics fail very, very seldom. I am using MegaSquirt for nearly 20 years, never had a CPU breakdown. Sometimes a connector failed because it was homemade and the position and the fixing to the frame or engine is try and error and must beimproved. I am thinking of vibrations or water spray in the rain. That is pretty easy to detect with the Laptop. I have an old one, I bought for 50 bucks, at the car. You can see what is wrong and repair quickly. Once the temperature sender was damaged and twice the wideband AFR failed. All was repaired within minutes, no problems, no worry. Many mechanical things need spare parts these defects only need some skill. After some years I did not even carry the spare CPU and the Laptop with me. I am fully confident that the things that stayed during the last years will last forever. Quote Link to post Share on other sites
JohnRoberts Posted June 24, 2018 Author Report Share Posted June 24, 2018 Hi Guys Further to this thread. I am in the next few days are going to order a set of parts from the above Co. Just at design stage at mounting the Bosch Injectors to the PI Manifold. Does anybody know how far the Injector should protrude into the air flow.

harrytr5 Posted June 25, 2018 Report Share Posted June 25, 2018 Andreas,that assumes you know what you are doing with the lap top engineering,I do not hence the break down truck. Yes electronics has got personal to the moon and back and I agree very reliable. Regards Harry. Quote Link to post Share on other sites
TriumphV8 Posted June 25, 2018 Report Share Posted June 25, 2018 (edited) The Pi manifold requires enlarging the hole to 13.5mm than make a phase 2x45 degrees at the top that the rubber ring can find its way. At the bottom/in the manifold grind the sharp edges a little bit. Thats it! Opel Omega V6 injectors fit nicely..... Harry you are right, the EFI requires some skil .... but the Weber DCOE do need that, too. That is the reason why so many people say that they are unreliable and thirsty. Many here in the forum got them working properly and EFI is the same. Unfortunately you need skill in several branches but the good news is that you need not be perfect in one of them. What I told with the Laptop in practice is like watching a cockpit of an airplane. You have a lot of instruments and they all show numbers. Your task is like doing the preflight checklist read them all and check if they are in limits or correct. If you learned what to do it is much easier to find a fault there than hanging under the bonnet and fiddle with wires and fuel hoses.

JohnRoberts Posted June 27, 2018 Author Report Share Posted June 27, 2018 Hi Andreas Thanks for the advice. I have today ordered a kit from Classic Car Injection. (spoke to them, very helpful.) Will report back how I get on. Will be a few weeks. Regards JohnR Quote Link to post Share on other sites
