My comment was based on my driving experiences of a 7 ok for short blasts but quite focused and tail happy


I've owned 2 Westfields and several of the early monocoque Robin Hood 7's all with various engines from a 1600 Ford crossflow to a tuned 3.9 Rover V8. I also had a Ginetta 27 with a Rover V8, with an Escort live axle.
You are right about the characteristics of the 7 but the bigger engines with matched diff ratio make them far more drivable.
Remember the 250 TR was a small car designed for the track first and foremost all be it with a big engine. The original TR must have been a handful with the V12 engine and skinny tyres.

Guy up the road from me has a tiger(?) 7 ...with 2 Kawasaki engines in ....sounds like an old f1 car

Well you know 7's better than me that's for sure .... when I drove the 7's I was much younger and er heavier footed ha ha .....get my kicks on motorbikes these days as have no space for a fun car just yet.

I've managed to strip the remaining paint over the holiday and sort out the dents at the front of the nose cone. I put in a couple of hours today lining up the front end panels and checking for fit and making little adjustments as required.
I'll get some ali sheet and steel tube this week in readiness to rebuild the scuttle panel. I should be in a position then to weld it all together.
I think I'm happy with the 7 style donor now, it seems to be the most logical and straight forward way to getting on the road. I just need to confirm the wheel base of the 250 before I start looking.


I've got the outer wings tacked onto the nose. I'll offer up the inner wings over the weekend and tack them on too. I need to make up a frame to support the whole lot whilst I make the scuttle and bonnet . Photos to follow!

I have Coys auction house near me and today they have a tr in at the moment
It’s a very narrow car , I was quite surprised

A lot of the Maserati's , Aston's and Ferrari's etc are quite narrow..it's the replica's that tend to be wide as they use more modern axles , jag stuff etc.
I personally think many of the jag based cars actually look too wide ...

Ferrari 250TR Pontoon:
Wheelbase: 96.2 inches
Front track: 51.5 inches
Rear track: 51.2 inches

C-4 Corvette:
Wheelbase 96.2 inches
Front track: 59.6 inches
Rear track: 60.4 inches

We did a 250TR body and fabricated the wheelbase to the correct dimension, but had to widen the body proportionately to fit the C-4 track. Overall result looks good after a few "tweaks" around the wheel arches and tail lights.
Done as an R&D project, one proto has been built. The big Healey shown was also a "from scratch" project.

Very nice indeed. Where'd you get the rear lights?

M,

I posted a link to the build thread for this fiberglass TR on the previous page, it is not mine. I am building a 275gtb on a volvo p1800. But if you click that link you can see how the TR builder made molds and cast the rear lenses himself.

Here's the link again for you

Any idea which page for the making of the rear lights? - I've trawled through most of the pages without success :sorry:

Along with the body there were several boxes and included were the original rear lights and lots of other spares. I'm not sure if they are common to anything else but they look authentic and the same as other TR's on google.

Lucky - This clip popped up on my YouTube recommendations list and I thought of you.

Since then, I watched a few of these Chris Runge metal shaping videos.

It is amazing what someone with the right skills and tools can achieve. :cool:

Good luck, Paul. :)

Hi Towed
The pontoon 250TR rear lights were also used on the Lancia Aurelia B24.

There are a few sets for sale

Just make sure you are sitting down before you see the prices!

700 Euros for a pair of rear lights. There must be a similar style unit from other cars of that era for a tiny fraction of that.
Some of the old school crafts men can do wonders with a sheet of ali! Luckily the parts I need to make only have slight curves and mostly just in one direction.

Some stunning work in that last photo, not sure about the highly polished finish.
I've seen the Cobra based one and watched the progress. As a one off its got the looks but it does look really wide. The Giordanengo body is as close as you will get for a true size and shape For me this sort of car is all about capturing the likeness of the original. The chassis is important but it shouldn't compromise the shape of the car.

It's hard to tell for me but it is probably a bit wider. I can understand not wanting to section and widen your body! Maybe a custom made parallel round tube chassis like the original car is the way to go. I suppose the power plant and rear axle choice will dictate everything.

In the uk things are getting very tight to register a customs built chassis car hence the choice of a previously registered chassis

Not much progress over the last week or so. I have sold my restored 1949 Triumph Roadster so I've been clearing the garage and making space for the 250 TR. The priority now will be to find a suitable "7" car.

Was It hard to let the triumph go?

It was a really long time in the making, nearly 4 years but it was a total rebuild from scratch. It is a fantastic car but it was the right time for someone else to enjoy it! The TR project is a one off, once in a life time find and to be honest I never thought I would ever own one.

Well that can’t be bad getting a dream car ...few of us will ever achieve that

Lucky by name for sure

The TR track is very narrow so the live axle 7's with an Escort axle are about right. I'll have to get the tape measure out with regard to the wheel base to confirm it one way or another. The 250 GT Boano chassis was modified a fair bit to take the TR body, I can't see that Giordangengo would have stretched the TR body 250mm just to suit the standard chassis, I will check.

Buying an on the road car as a donor is the obvious route for me.


Well, the Triumph Roadster has now been collected so I've the space I need ( and some cash !) to get moving on this project.
I have measured the approx. wheelbase of the body and it is as I thought, much closer to the original 250 Testarossa at around 2300mm, than that of the long wheelbase Boano, the original donor.
Following a wanted ad in my local paper I have found an extremely well built, MOT'd and SVA'd Locost 7 with Ford running gear and very low mileage. I'm going to try and do a deal this week with the seller.

Good luck with the donor and look forward to seeing the build commence.
