Tuscan Challenge Roll Cage Hoop

[Gdguyswin]

A change of regs means I’m looking to make my hoop higher (by at least 75mm) - has anyone made a similar change to an original roll centre cage? Any idea what the highest hoops that have been signed off? Thx

[Gdguyswin]

Thank you - I have made contact but rollcentre has recently changed hands and I was trying to help out the new owners by finding a set of drawings for them. I’ll post a few pics of cars that look like their hoops are higher than the original 85mm

Hi, great pictures.

You’re absolutely correct about the hoops and their installation history - what I’m saying is that picture on the green car shows a much higher hoop than the original (I have the engineering drawings) and was wondering if this had been a modification to the original or a new cage?

[Gdguyswin]

I’ll look it up thanks. Re pictures - fill your boots. I keep an eye on most Tuscan Challenge websites - yours included and enjoy the pictures - and no I’m not a stalker lol

Different regs for me - the top of the hoop now has to be 50mm above the top of my helmet in my normal seated position - line drawn from top of hoop to the top of the cage in front of my head.

[Gdguyswin]

Actually that makes sense - I’m going to take a look at that tomorrow. I didn’t think there would be 50 mm in it but anything would help. You know the car Perry - I bought it off you lol

I know a little about getting wet as well

Plenty of fun. Competing in the European Race Classics series. Back to running a Rover V8 hence the change to the bonnet. Just starting to get some grief from scrutineering on height so need a taller hoop or lower seat or both.

And yes, it rains here too!! Sometimes

Hi, it’s my first season and the car is definitely competitive, though I’m learning the ropes. Reverse grids take a bit of getting used to. The series is a North Island series and runs across three circuits, Taupo, Pukehohe (which hosts the V8 Supercars) and our newest circuit Hampton Downs.

Finished 9th last time (out of 27 starters) and in a wet race two had the fastest lap before retiring. There are several very fast fords (6.7L Penera Capri’s out of South Africa) and a scorching RS2000 that is the current series leader.

It’s a lot of fun and a good bunch of people.

This was our recent gathering - told this is the most TVR’s in the one photo in the Southern Hemisphere - mine was missing but Pascal’s yellow Tuscan is on the right. Running 345 wides at the rear !!

Yes that does look moist.

The V8’s just do one round in NZ and it’s Puke. We host the Australian Endurance Series at Hampton - maybe it was it you saw.

Does anyone know how to contact Tim Davis - I might see if he has a homologation certificate for that raised hoop? Save me a lot of time

Hi George

Here is the link to the TVR that Tim currently has for sale on pistonheads. There is a way of contacting him through there.

PS. Does Carl Hansen still race his TVR?

Thank you - I will try that

Carl hasn’t been out this season - not sure why tbh. You can check out his website here and see a few video’s as well

my seat is bolted directly on top of the outrigger so I've already taken that height out - I'll have a look at your suggestion Graham - presumably the seat you mention is on feet as if it was fixed by a bottom rail mount it would still be on top of the outrigger?

[Gdguyswin]

We must have different outrigger patterns - the outside would fit but not the inside

[Gdguyswin]

You can see from the picture that my rail would sit on top of the inside bars

Gents Do I have a different pattern?

Thanks gents that’s very helpful. Looks like i’ll Be getting out the grinder and the welder over the weekend!! The GrP floor in the car is already cut through and the steel plate you can see is welded to the top of the outrigger. I should get 25mm - 30mm which at the bottom will be worth a lot more than at the top if my Form 2 trigonometry serves me well. Will let you know how I get on.
