Thanks buddy, there is one more build video to come then some.more action videos hopefully. Yeah man I would love to have you engine on there just gotta sort the car first:)
@@dizzy_cap_car_showCheers dude. We shall see what interest it gets. First video since the RR restoration series. Be interesting to see if it gets more views
Making life very hard for yourself with the limitation of that ECU just working with fuel pressure and advancing the distributor. I'm currently running a Speeduino ECU on a TVR Chimaera 4.0 Turbo install. Junk the AFM and dizzy and enjoy full control over map sensor controlled fuelling and ignition maps at any point in the rev range. Will drive so much better and really cheap to implement. A Speeduino ECU can be self built for around £100.
@@robinarmstrong8886 couldn't agree more. It would be great to get it on a standalone ECU. But unfortunately I wasn't able to commit to the time to converting everything over to stand alone. So he went down the Tornado ECU route.
@@lozl No worries. Sorry if it sounded like a criticism. Passionate about putting a new lease of life into the humble Rover V8. Love the content, have subscribed. :)
@@robinarmstrong8886 no worries, honestly I would have loved to have put an ECU on it. I have done so with my car, there are massive advantages and its so much fun. But i have so little time to do the work for the guy and wouldn't have wanted to half arse it. This is a pretty good way to go. Next time... :)
btw the sd1 doesn't have a actual rev limiter it'll rev until the hydraulic followers overpump/something brakes, the redline of a standard sd1 is 5500rpm, the ecu doesn't control the ignition only gets a earth pulse to know rpm for injection pulse, a standard 3.5 injection engine is 190bhp so assuming that 203hp was at the crank I would say that 4.3l is very tired, should be up in the mid 200 with a ported tvr heads
Oh that's interesting about the ignition. It makes sense though. As you can tell I don't know too much about the working of this very early injection system. As you could see we were reluctant to rev it any more, so I'm pleased we managed to find peak power. I didn't really know what to expect going into the work, I was quite pleased with the result at the time, it certainly feels nice and quick to drive. As I've looked into it though, I have realised that it must be down on power somewhat. Its worth noting though that it has a standard 4.2 camshaft fitted, not the camshaft that would have come in the TVR engine. Big valves, big ports and runners, and the bigger throttle body all give the best effects at high rpm, which is exactly where the standard camshaft will be limiting flow somewhat. That said we have also thought the 4.2 might be a little tired. It will soon be removed and a 4.6 put in its place with the ongoing work on the car. We can then assess the condition of that 4.2.
@@lozl the injection system is a borsch system that Lucas licensed. I don’t believe you can run a mix of components from either manufacturer the system is called L jettronic Standard can shaft. Would think it should be about 220-230hp. With the other tvr bits. a standard 4.6 is 220hp with a restrictive inlet so missing about 20-30hp that 4.3 is
you need lots of initial advance.. right before it kicks back at the starter, and then correct total advance for wot. + vacuum MANIOLD advance to get to 30ish degres at idle for good crisp idle. that is my guess at least.. might be wrong
@@lozlI got all that from watching Tall John's Fun Shop , but I think he knows what he is doing. hehe.... :) I just worked on hot Rover 3.9 running 14-15 initial, 36 total, lighter springs + 16manifold vacuum advance. runs good, should possibly have more initial but have to stop mechanical earlier in that case.
@@theservant752 I kinda wish we had a stand alone ECU, then we could have found the perfect timing everywhere. Obviously the limitation of a dizzy. We found very little difference in torque (like pretty much none) at quite a few different timing settings. You're clearly seeing some effects for yours timing changes..... Someone else has suggested that perhaps the cam timing is out, making it less responsive to changes in ignition timing? Something to look at now that engine is out and thr 4.6 is in.
Really nice to see it up and running, matey. It'll be nice to get booked on - for some imaginary time in the future when the car's actually done...😊

Sounds absolutely awesome. Wish my Disco went like this 😂
Agreed. It always makes me smile when he pulls up :) the headers make quite a difference I think
Sounds well I am just getting to grips with this EFI stuff!
@@classic_britain its good. I love it :) glad you enjoyed the video
Nice man! Nice to see a vid of you playing with a cat properly on the RR!
Cheers buddy. Not the greatest video from an entertainment point of view but hopefully it inspires confidence, maybe?
@@lozl it’s good man, nice chatter about what you’re up to etc 👍 good shots of the car revving up on the dyno! 👌

@@That_sd1_vitesse that all sounds plausible. If I had a compression tester might give us a clue as to engine health.
