Putting my HSV back on the road

Quite right!
Been meaning to ask you John, when you had the 3.9 diff fitted, who recalibrated the speedo for you?
And was it the main ECU or just the cluster that was reprogrammed?
Cheers.

Monkfish did my 3.9
ECU sorts the speedo. It's now within 1 or 2 mph of true, confirmed by satnav.

Thanks, It's a LS1 C4B with various upgrades & a Vortech V3 Supercharger with FMIC. 502bhp @ the wheels (Surrey Rolling Road). I didn't have a decent set of 300kW engine covers hence the other cover.

I nice cam will wake the old girl up even more

[JAMESHSV1]

[quote=Lincsls1]I'm interested in how your car performs. I'm assuming its very fast of course, but talking more about the delivery of power.
Is it like a turbo car, really taking off after say 3k?[/quote A centri chargers power is very linier iand progressive but can be easily prevocked I had a procharger D1-sc fitted to my 04 cv8

[Lincsls1]

Yes, I'm really rather intrigued by the idea of a charger like these. I just can't understand why the kits are around £6-7k and then there's the installation cost.

She already has a bespoke ground cam in there.

Also consider Carl Herkes in Southampton. He has very close links with Luis Sola who can sort out any tuning needs.

My car is currently at TopCats, cannot fault their work.

Cool did you get the heads reworked as well

[TerryS]

I have spent the day draining fuel & fluids. New petrol with octane booster. Try to start her and she runs for literally 2 seconds then dies. Someone has suggested the VATS system?

[fred bloggs]

I was under the impression the vts-r had the 3.9 diff as supplied.

I used greg at protuner in coventry for my mapping.

Have you put fresh fuel in the car ? Id be looking at new fuel and then fuel pressure at first, with a lay up of that length.

Great looking example by the way.

No idea on the diff ratio, never looked into it. I know it runs a different diff to the other cars but I can't remember the details.

The car has an uprated fuel system with a swirl pot, 034 fuel pump and adjustable FPR so I would be surprised if it was fuel pressure. I have put new fuel with octane booster in.

Thanks for the kind words.

The GTS-R did get the 3.9 diff as standard.

It was me asking another CV8 owner, who had changed his diff to a 3.9, about speedo recalibration.

This, without question.

Wouldn’t hesitate to recommend Luis to tune your car...

Sorry missed this, no the C4B heads that were standard on these cars flow better than stock LS1 heads so I stayed with those.

Thanks, I have contacted Carl via Facebook.

[TerryS]

I found a few more pictures if anyone is interested

[Lincsls1]

Stunning mate!
Is this car a keeper?
They are so dam rare, and pretty practical as well. In fact I don't think I've ever seen one on the road.

[TerryS]

I have kept her for the rarity, she is #2 of 16 that I believe were sold in the UK and I was told 11 years ago there were only 11 still in existence. My uncle had her from new so I am the 2nd owner.

Is she a keeper, who knows.

Good decision.
