A couple of weeks ago I drove Kingley's 4.8 demonstrator. I don't know if they use Rob but it wouldn't surprise me. That was a good engine. It certainly have the Rangie the performance to bring it up to date.

I think you are right, I seem to remember they did use V8D, just need to finish off a few small bits Rob recommends a smooth bore induction pipe and a different K&N (my one uses the standard tin can air box and he reckons its a bit restrictive). I am now researching the exhaust, due to the larger ports it appears I need tubular headers and a larger bore system my problem is my car is a 92 so still needs cats (don't want the grief I had with MOT when I de catted my old TVR), any thoughts?

Damon at Kingsly has his own stainless system you can buy. It's a thing of beauty. As are the manifolds.

One of the important things to do with the bigger engines is to ensure that the torque curve fits the ZF working ratios. I've driven a couple of 5 Litre conversions where the engines were sublime but desperately needed the right cams to make the most of all that power when mated to the ZF. Although, if you use the electronic HP24 inards in the HP22 case then you could reprogram the change and lock up points to fit?

Must look at that, not sure about the exhaust looks pricy plus no cats either, Janspeed seem to do set up which looks like does the job, auto box feels okay at present but am being gentle as am running it in............as an ex-overfinch owner, what is your take on the steering?, did over finch use a different steering box?

One of the Overfinch options (that few had) was the Adwest Engineering box.

I'll be fitting one to the 2 door as it made road driving much improved on the OverFinch.

Adwest were bought out last year but the units are still available.

Hi Mark,

Many thanks, isn't it always the way, have just ordered a full Janspeed system..............ah well its only money

[Markh]

now maybe this is next..........

I bought a whole car to get one part the other month and two days later that part cropped up in Rbay after two years of waiting!!!!!

More trouble than worth. None of the forced induction RV8 stuff has ever been good enough.

Looks pretty though, did think about CS supercharger set up (seems to wrk with TVR's okay

Seen many Tivs with FI running reliably?

All these kits are cost saving compromises. Either no changing of CR or no use of a smart enough ECU to handle the new variables.

I think when you add a home brew FI then your engine becomes a disposable item.

I take your point, am looking at some kind of proper ECU (have motec on my porsche, seems to work well), have a friend with the charger kit on a chimaera 500 seems pretty good

I don't know Motec. I use Syvecs on my TVR. It was designed for running FI rivers and is an incredible bit of kit. It makes my engine run incredibly smoothly with no flat spots, will adjust timing for almost any fuel type, detect knock and remove and controls the fans so maintains a constant temp regardless. It's amazing kit and definitely the right product for an FI set up.

There are two or three kits for the RV8 Tivs and one looked at them quite closely for my Rangie project. It was talking to the people offering the kits and seeing the work that made me give up on the RV8 if I wanted to go above 300 bhp and keep usability and reliability.

I definitely wouldn't muck about with a new V8D 4.8.

Hello chaps

The 4.8 in the kingsley demonstrator is from ACR with a standard cam and heads.

we have just finished a 5.4 litre 2 door for a client in switzerland - engine from V8D - we used kingsley exhaust system but removed the back box and just went straight out.

this is probably the fastest 2 door in the world - and the best

2000 hours - total cost 210000 euros

enjoy

Hello. Lovely car that. I was reading about that car the other week. Can't recall if it was on PH or LandyZone.

Zen's 2 door might be quicker though.

[vjj]

I posted some vids and some pics of the build on landyzone

In a drag race against a 5.7 HSI Overfinch it munched it

It can very nearly keep up with my 6.3 litre 90 and that
hits 60 in 5 seconds dead.

By the way I bought the disco Overfinch at Kingsley
It is a great car - but the manual box is a pain
Currently having Autobox fitted and engine being rebuilt
- stroker crank to 6.3 - edelbrock heads and cam etc.

Excellent. It's a nice car but as we've discussed before the clutch was a bugger.

How much performance do you think is given away by switching from manual to the ZF box?

[vjj]

None

Cos by the time we finish with the engine it will have
380 bhp and 450lbs of tq

Which would destroy the manual box in a flash

I thought that car had a US box in it. Is it just an R380 then?

I'm in two minds with the 24 internals going into my 22 case whether to stay hydraulic or go electronic. I can't be areas with the compushift but it would have the advantage of increasing the line pressures a little and changing lock up.
