Sagaris Rebuild

[BIG DUNC]

Dave, you are a glutton for punishment. I remember seeing photos of the Chim when you started.
This looks like a very nice project. Good luck and I will follow it.
As an aside, are you keeping the Chim as well, or will that have to go (or already gone)?

What are you plans for engine management? Definitely room for improvement over the original.

Syvecs is the way to go in my direct experience.

They were the first to crack the problem of fitting knock sensors to the S6 when everyone said it couldn't be done, and then others followed suit.

Obviously others are available but you won't get any better that Syvecs in my opinion.

Hi Duncan, good yo here from - hope all is well?

No still have the Chimaera, with no plans to let it go.

Here she is now …

Im not too sure as yet, the plan is to complete as a rolling project with chassis and body completed for winter, then i will look at powertrain and management system. Great to hear peoples thoughts and suggestions however!

Its looking good.

I am all well, just spending a lot of time (working) overseas at present, so have not spent much time in the Griff.

Morning all,

Starting to make some progress on the chassis rebuild.

Question: Does anyone have any images of the brake pipe routes? I can see snippets of images - but if anyone has a body off that perhaps can show me them in its entirety - that would be great.

Few pics so far...

Is it possible to add more side impact protection (any modern SUV will ride straight over the low level of the current side impact tubing) like a door cross bar, and also rollover bar/tubing? The existing chassis is very sub-standard by todays metrics.

The Sagaris already has a full roll cage. I think it also has side impact bars in the doors.

The picture is showing only the chassis

A roll cage and side impact bars should by modern standards be part of the bare tubular chassis.

Bit late given the chassis is painted. Unless the OP decides to go back.

You could ditch all the electronic stuff and turn it into a proper sports car, well at least get rid of some of the gear that's OTT

What electronic stuff?

A brief comment made during a wider conversation I was having at a certain TVR Tickler garage was that all the various 'convenience' ECU's (windows, mirrors etc ..) could be replaced with one Raspberry PI or similar. Would certainly make sense to locate this much smaller single unit somewhere waterproof away from heat etc ..

There is a roll cage and side bars moulded in the body that bolts down to the chassis, so all tied together once the body is back on.

In that case I would look at how to protect the corner of the chassis behind the front wheels in particular. That corner gets shot blasted.

Yes a good plan. You can buy Kaylan sheet in various thicknesses and tidily zip-tie it to the area, it's the stuff mudflaps are made from, tough!
Fitted on my T350 from new and chassis is still fine at 73k.

How does that actually differ from the chimera chassis. ?

The Sagaris is meant to be much stiffer, but the chassis doesn't look much different to the chim or cerb ones I've seen

The roll cage must have a significant benefit.

That will be the roll cage that incorporates... door posts, steering column, roll cage and the 14 bolts that attach that to the chassis. to the outriggers to the central spine. THEN this is the wider track chassis. Here is a link to a Tamora build that the Sagaris chassis evolved from (the sagaris chassis turns into a generic chassis that late T cars have, note all the additional wishbone pick up holes)

For a separate roll cage to provide a significant stiffness benefit then it needs to be made of thick tubing (similar to the existing chassis) and be bolted down at multiple points on large spreader plates. The TVR backbone style chassis is about 50-60 years out of date, so I'm skeptical that a skinny roll cage inside a fibreglass body is going to add much.

I'm pretty sure the Sagaris was rolled out back in the day with "50%" stiffer than any previous TVR, and the journo was all commenting on it as a big step up from the T cars in handling due to a stiffer chassis.

I'd love to see all the TVR frames side by side to compare what actually was the frame, and what was simply a wider track

Not sure why you've got your teeth into this one but if you want to google photos of Sagaris interiors you can see some of the not so skinny roll cage bars running down across the rear side window.
