2010 model, 5.0SC or TDV8 3.6

Hi guys.

I've got a 2005 D3 TDV6HSE and planning to replace it with a 'faster' RRS. I'm in Australia and over here, a used 2010 5.0SC costs almost same to TDV8 and spec wise almost identical as well.

I've only had chance to test drive a 5.0SC for 10 min which seems pretty good, yet it's raining and didn't go fast.

I believe 5.0SC will be faster than 3.6 TDV8 if not chipped. I'm just not sure will TDV8 drives as same fun as a 5.0SC?

I know fuel wise, TDV8 could save 30% probably yet I don't expect to drive over 10K KM a year so SC is also acceptable.

On my 2.7TD D3, when rev goes to 2000, it's very smooth, same smoothness to V8 petrol. Yet when idle or just start from stand still, it's still a diesel feeling. Not sure if TDV8 is similar.

Also TDV8 will have EGR/Turbo issue. How about 5.0SC? Does super charger have it's life? Or maintenance wise (I do all by myself), is there any big difference?

Many thanks in advance.
Tom

I’ve had 2x tdv8’s L320’s 2x sdv6 L320’s 1x sdv6 L494 & I now have a my14 5.0SC & believe me the SC is in a totally different league,don’t get me wrong the tdv8’s don’t hang around & neither did the sdv6 L494 but every time I get in my 5.0SC & put the foot down it puts a smile on my face.

Thanks Andy. It's not due to L494 VS L320?

BTW, how come you change your car annually?

I’m biased but if you want to have fun and don’t do much mileage then for me it’s the SC, if you do a lot of miles and don’t fancy towing a petrol station behind you, it would be the TDV8. 2012MY RRS 5.0 Supercharged Autobiography (Current)

The reason I changed form the my12 red edition was because I fancied a L494 & one came up at a dealers the spec I wanted then after I’d had that 12 month I called into the local LR dealers just for a nosey & they had the supercharger in & when they fired it up I just had to have it,I’ll probably keep this another 12 month then sell it just before the warranty runs out,I’ve no idea what I’ll get next I would like a svr but they are just out of my price range as I like to buy outright.

The TDV8's EGRs don't seem to be the problem that they are on the V6s. Mine was still on its original EGRs when I had the glow plugs changed at about 160k miles - only changed the EGRs because they had to come out anyway so it made sense.

The TDV8's turbos are a known weak point but being careful to allow them to idle for a minute every time you stop seems to help mitigate the risk.

The TDV8 is an excellent engine, that sounds like a V8 when idling and when the right pedal is pushed, although not nearly the same extent that the 5.0SC does!

If you can get the 5.0SC at the right price and your fuel costs (10k miles seems reasonable) are ok, then go for the 5.0SC. Let's face it, are you ever going to regret the performance? Laughing Oh, and yes, the 5.0SC is much quicker than the TDV8 even if the TDV8 is chipped. 500bhp will always beat 300bhp when wound up, even if the TDV8 would lug better from low down.

If you think you'll do big miles, then the TDV8 would likely be the better bet. The low down grunt of the TDV8 is a real bonus when cruising along and needing a bit of extra go e.g. on a motorway. My SDV6 is not a patch on the TDV8 in such situations, even though it's pretty nippy when wound up (and once the gearbox has decided what to do!). 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

I have had both TDV8 and S/C although the S/C out performs the 3.6 it still has plenty of go, I did have it re-mapped so it had enough get up and go to get you into trouble. I have had the S/C re-mapped and supercharger pulley upgraded as well so have a fair idea on both as did have them both at the same time and would go for the S/C every time mainly due to the grin factor . If you want 24-25 mpg go for the TDV8 if you can live with 13-14mpg then go for the S/C but at 10k a year my personal choice would still be the S/C every time. Worth bearing in mind the early 5.0L did have timing chain tensioner and also supercharger nose cone bearing issues so would listen for any undue rattles from engine when idling.

Cheers
Col

Thanks all for the inputs. Then SC will be the only one I'll look into.

Since I'll just go for less than 7K miles a year, fuel consumption is not too much a problem.

I should say if I got a TDV8, then I'll miss the SC from time to time I believe. Maybe my next FFRR TDV8 4.4 in 7 years (till the price range for a 13 model falls into my budget range) will be the time for me to go back to diesel.

I still remember 5 years ago when I first test drove the 4.4V8/2.7TDV6 D3, the smoothness blows me up! Can't imagine how good the car is! Especially upgraded from a 2002 4.7 Jeep Grand Cherokee.

Gonna be sad to let the D3 go, apart from the performance (underpowered tdv6), it's such a nice solid car.

Really excited and hopefully can get a 2010 RRS SC in 2 weeks time!

Watched some video on youtube. Seems by design, those timing chain guide will fail for sure... quite a timing bomb here.

Do you guys have any idea if during the inspection, any chance I can find out if it's been already replaced? Many of them just got 'stamped' log book which is totally useless in this case.
