TR4 Surrey Hood

[TR4-Wright]

Is it possible to fit a TR4A or TR5 Surrey Hood (H Frame) with all the fittings to a TR4 , and if so is this a better fitting option. At the moment i only have the Surrey back frame and glass fitted but have no other fittings or trim as yet.

 

Any Advice would be grateful. Cheers. Norman

The main hood frame for the TR4A & TR5 is a different fitting to the TR4

at the front, as I'm sure you realise.

BUT - for the surrey top, they are the same. That means to fit a surrey

to to a TR4A or TR5, you need the wider windscreen top ally capping that

projects beyond the windscreen frame. The surrey top is designed to fit

into the slot formed by the projection, the same as the TR4 hood.

 

Alternatively, you could alter a surrey top front and fit the front part

of the later-design frame to fit into the windscreen frame. Not necessary,

but there are those who have done it and it seems to be effective.

 

The back frame and glass are the main pieces to have, so you are more than

half way there.

Does the TR4 hood lift up at speed creating wind and rain to ingress, if so whats the best option to improve.

Hi Norman,

 

Hoods will always tend to lift up at speed - that's the effect

of air flow - no way to overcome the physics.

 

I would expect the TR4A hood to be better than the TR4 design but

much depends on a tight fitting hood (or surrey top).

This comes back to the initial fitting and quality of the item.

The hood should have a flap on the inside to wrap around the frame

and counter the natural lifting effect.

 

The TR4A fitting to the windscreen must be better than the TR4 design

(though I have little experience of this) but much comes back to the

quality and fit of the parts. The small lip on the windscreen where

the TR4 hood locates is critical - easily affected by the quality

of the repro hoods and windscreen cappings.

I know it's not a purist approach, but I still reckon there's a lot to be said for the judicious use of velcro when it comes to sealing the edges of hoods of whatever sort. It's a b*gg*r to open the hood of course, careful recourse to a blunted knife blade can be required, but it doesn't half reduce wind noise and water ingress.

 

Yes OK, I'm a heathen, I'll be getting me coat then . . .

Here, let me help you on with it !

 

Seriously, though, there's probably more water leakage into the car

when it's standing then when it's driven.

 

I remember on my old TR3A, before the days of velcro, I put a couple

of self-tapping pegs into the top of the sidescreen frame and lift the

dot fasterners into the hood.

It worked very well in reducing hood lift and noice, although I kept

forgetting they were there and opened the door without removing the

fastenings.

Thanks pal, that would be you and who else's army then ?

Hi Norman, On my Tr4 with surrey top I have only had 1 occasion where the vynil top has come out from under the windscreen

capping, although it was at about 70 mph ( not to be repeated its quite scary ). On reflection I think I had not tucked the front in properly when I put it on in a hurry as it was starting to rain. I have not had any general problems regarding water ingress

I have read some where about someone fitting a TR6 header rail which obviously clips down a lot firmer but you would need the rail and windscreen capping together with a new surrey top vynil to do it.

 

Hope that helps

In my experience a PROPERLY FITTED TR4 top is quite leakproof. I drove one for five years back in the 1960s through many blizzards and rainstorms, and it never leaked.

FWIW my 4A's hood is totally wind and watertight at 90mph+ . I know there is a modification to incorporate the 4A's style of fastening into a Surrey but I'm afraid I don't know the details.

Hi Norman I've converted mine to a TR6 header and fixings, get in touch if you want a chat, relatively straight forward and well worth the effort after my original design surrey top 'Popped' a couple of times.
