TVR, Range-Rover, SD1 & Scratch-Build Kitcar

I am proud to announce that I am the owner of no less than 4 Rover V8 engined cars!

They are as follows:

TVR Chimaera 400 HC (1995) with Kent H218 camshaft & V4 Rover V8 DIS Engine Management System;

Range Rover Classic LSE (1993) with TVR 4.6 & Megasquirt DIS Engine Management System;

Rover SD1 SE (1982) with 4 litre Rover V8;

LS350 Kitcar (scratch build, still in progress) with 3.5 litre Rover V8 - Kent H224 Camshaft and modified heads.

So that's 2 cars on fully mappable fuel injection and 2 on twin carbs (SU's on the SD1 and Strombergs on the kitcar).

Sounds grand - welcome!

Pics always good as well.

Can you tell me anything about this photo:

Might be one for my manifold archive

Hi Elliot,
are you going to start an archive for Chevy manifolds? because if you are I have one I can post a picky of

Best regards
Mike

Hello Eliot,

We would love to tell you more, particularly as we have looked at your site many times in the past. At this moment in time though, we wish to keep this one under wraps until it has been completed. We will try to ensure that you get the first proper pics!

Kind regards,

Daniel & Nathan Lloyd

Interesting pic Eliot. (as always!)

v8nut - I'm interested in manifold designs too since I designed the twin plenum (almost Cerbera like) system and gained over 60bhp from it alone on my Griff - I wish you the best of luck as there are considerable gains to be made.

If you have a means of getting 44mm ID aluminium tube bent (or even cast) into tight bends I would very much like some!

Hello,

It's good to hear that there are other enthusiasts and fellow engineers out there exploring the possibilities of the Rover V8 further, we really feel that there is more to be gained with this fantastic engine.
I noticed that you are also using a mappable ecu to control both fuelling and ignition, we believe that this is the first crucial piece of the jigsaw.

What internal radius would you require for the bends? What overall dimensions would you require? (i.e.: leg lengths?)

Regards,

Daniel

The mappable ECU was the first thing I did to the engine. It make sense to do this in so many ways.

The bends need to be as tight as possible - there is no space to work with unless I decide to fabricate a new manifold base from scratch. (Not my first choice because the ported one I have seems pretty good)

Leg lengths would be short: 50mm or so at each end. I can always cut them down, but no-one's made a good putting on tool yet

Bend radius is again tight. I'd need to measure it, but I guess it's 60mm.

It might be easier to show the use:

This was my first attempt at a twin plenum intake. It works well, but I can't help thinking that if it was all aluminium it would work even better.
