Volvo 260 V8 turbo estate

This is brilliant, love the noise. I wish I had the balls to turbo the RV8 in my TVR 350i.

I've fitted twin turbos to several V8's, check out my twin turbo moggy thread that's a Tvr motor 👍🏼

I thought I recognised the town in the third video, having just looked again, I used to cut a lot of the larger areas of grass visible between when he's reversed out of the driveway to getting out of the town.

Been caught swearing at people in that narrow bit before because there's more than a few locals who seem to think a Transit tipper and a big flatbed trailer don't need 'any' space to maneuver, but I digress...

I would also add its been a few months since I was doing that round, and I don't recall seeing the Volvo whilst I was on it.

Got out to a cars and coffee evening today at Cafe 35 in Whitehaven, Its real nice inside and the coffee was good too.



Didnt stay in long though as this lot were outside:












Unfortunately I havent been able to do any more fiddling with the Volvo. Nothing worth an update anyway! I have been working on cool things though

I'm internet friends with the guy who runs the Mk1 escort estate (funnily enough)
Had seen photos of your car but didnt realise it was a V8.
Very cool car

After a while at full throttle/boost you end up looking like one of the red arrows leaving a big smoke trail behind the car. Luckily its not the turbo falling to bits, but the leaky incontinent nature of the Rover V8 which results in a good few drips onto the red hot heat wrapped exhaust which creates the perfect smoke machine (very James Bond)

The RV8's suffer from high crank case pressure when your giving it some already and the turbo definitely isn't helping this, so i jacked the car up and had a look underneath to try and find where its coming from which was the back of the valley gasket (common issue on RV8's) and the rear of both rocker covers. I had a pair of new rubber gaskets lying around as you do, so i chucked them on and gave the lifters a quick check while i was in there:

Both split:


Looking good:



Both of the existing breathers were clogged up (strange seeing as everything else is so clean on the engine) so i went down to the local hardware shop and treated myself to a new pan scourer



My missus got excited at the point thinking that i was going to do the dishes, until i chopped it up and stuck it in my breather:



I also modified the oil filler tube to act as another breather so there's one on each bank. Filling with oil will still be relatively straight forwards as the original breather screws off. It looks pretty cool too:



Mesh top and bottom with retaining wire so Wire wool doesn't get chewed up if it fell into the rockers!

Another Intermittent problem i have had is the over run fuel cut not kicking in.

When you come of the throttle and coast, you can set the ECU to cut the fuel and save you some money. It uses the MAP, RPM and throttle position to work out when to do this. Mine was set to come on below 25kpa, 3% throttle and only work above 1300rpm (so it will still idle) . But when i logged it and looked back through it, the tps moved around between 0 and 10% whilst my foot was off the pedal. MAP stayed the same so i knew it wasn't opening and closing the throttle, so it was a duff sensor or a dodgy earth.

Upon closer inspection the TPS sensor had some knackered wires so i chucked on the spare and its good to go after re-calibrating the throttle!



Once that was on i gave it all a wash down with some degreaser to wash any remaining oil away and took her out for a spin.

Success, No smoke screens, no oil stains under the car either daslandroverman

And slightly better fuel economy now the over run fuel cut works properly!

The garage build was delayed by rain today, so i went over to my parents today to sort their car. Stopped off on the way home to make the most of the greenery before it all falls off the trees!




Still a little smoke after long periods of full throttle, but no where near as much as before. Might have to take the inlet off and check that gasket is sealed properly!

Its been a while, but i've been out driving the car! Which at 20mpg best, see's it back in the spiritual home of the V8's



And the spiritual home of Volvo's



I've also been working on it a bit...



I've had an on going issue with the spark being blown out when i came onto boost. This can be a few things, but the plugs were my gut instinct.
When i got the engine running i just used the recommended plugs from the local motorfactors. These were NGK BPR6ES. These are resistor type plugs (not entirely sure what effect that has) and were gapped to about .040"

I knocked the gap down to .025" and it helped alot but it wasn't ideal as its a very small spark gap. So after a bit of research and some digging through the megasquirt forums, I ended up choosing the NGK BP9ES. These are 3 heat ranges "cooler" and not a resistor type. I gapped these to .038" fired them in and she was running at full potential



High tech!


Anyway, after driving around for a week or so with itch arms from rubbing up against the heat wrap changing the plugs, i was ready to drop it off at Anne Summers and stick a note in the window selling the countrys biggest vibrator...

The prop in it was the problem. The original fitter of the engine made up an aluminium extender which adapted the volvo prop to the rover gearbox.



In theory, there's no problem with doing this. But when it was made, the two faces haven't been machined on the same centerline so the prop moves in a kind of elliptical motion (correct me if i'm wrong) making the car shake like a pooing hound..

Which brings us to where we are at now.

The prop is currently being brought back to life at my friendly neighborhood prop-shaft dude Dr Prop (yes really!) who's making it longer and less vibratorish



Ill get some more videos when its on the road again if people would like some?

I like this, a lot!
