Cabin Pressure and High Speed!

Recommended Posts

We are looking to attend Ten of the Best next year. One of the favourite events for the Supra is to be in the top 5 is the top speed run.

 

However, Supras (Being frameless Coupes) have been known to pop there glass over 190mph.. Obviously we need to find a solution and was wondering if anybody knew or could point me in the direction of information about and internal and external semi sealed environment pressure differences and the ups and downs of differnent methods.. Ie Event into the car, Sealing the cabin etc..

 

One way we thought of is changing the doors for the day, and pot riviting and sealing lexan windows to the body, and using the hatch for acess.. Any educated information greatly recieved..

However, CRD did 201 or 202 with FRP doors and lexan windows which are floppy as hell and they were fine.

 

Gaz.

 

Is that the run on the TOTB vid where you can see it all bending out of shape and then the VCR gives up as the forces involved are actually pulling the tape away from the recording head. That was mental.

I wouldn't worry about building the car to that spec, Supras and TOTB just don't go together, with most either breaking before they get there or on the day, quite early on :D

Gaz i think CRD ran the Lexan windows and FRP doors as part of thier weight saving program and nothing to do with stress on the Stock glass - could be wrong though, but its a lot easier smashing and ripping a Front screen out than trying to smash it in thriough the car

Oh yeah, thats how I understood it too.

 

I don't think you'd have any problems with pressure.

 

As Michael pointed out, getting that kind of speed in UK competitions is slim to no chance, Elvo was one of the best places to do it however next year you will be lucky if its still 1.25 mile. Some of the V-max events have 1.5m runs at Brunters.

 

Most other places are very private and you'd need connections to get in there (various RAF Bases, Pro-drive, Aston Martin, Millbrook etc all have 2 mile+ straights)
