The first time I saw it mentioned as ROPS is in the 2014 Blue book it may have been in 2012 or 2013 as well but I don't have them to hand to check. I have been competing since 1974 and the first time I saw it I thought what's that all about. It's probably to avoid confusion between Roll over bars and anti roll bars.

Jedi were the main culprit, OMS on various cars and even Pilbeam. The ROPS on the Endaf/Knocker Imp was lacking in tube dimensions,bracing and material in some areas.
The regs apply across the board to all disciplines, Hills Sprints Circuits, Rallying etc.

Hi Roy,
yes that was what I meant by changed. That some cars had to be modified to meet what they should have been built to in the first place.

Hi Steve, That is what I'm doing to the Imp, actually both of them. They were used on circuits for years with ROPS that have never complied with the Blue book.
Yep, I agree, doors are hinged different and some of the panels are a bit different.
Mike My mate had a photo of Bert Ray adjusting something on a supposedly Ray Imp that looked an awful lot like the Owen car, but that was in plain dark blue.
I'm pretty certain that only 2 Ray Stiletto's were built, certainly Bob Jarvis's was one. Tony Sinclair at JADE's may know , he i/was Bert Ray's nephew .
The Darrian website certainly has a price list for Bob Jarvis Bodywork ,the tail section being the same shape as Rob Knox's car.
The body panels are definitely Jarvis as are mine on the Maroon later orange car, the doors on the Knox/Owen car are like the Davrian ones, the doors on the Maroon/orange car are ali like on the Jedi Imp and are what Tim Duffee calls Jarvis panels.

Hi, I have now had my Imp out on a couple of events. It goes well but needs a bit of work on the handling. It is fine on the twisty/fiddly tracks but on fast corners it is a bit tail endy. I think I know the cure, so we will see.
The power is good with around 200 bhp and 164 ftlb torque before traction was lost on the rollers. I hasten to add that this is not an Imp engine. It is a std Honda Blackbird supercharged and on Methanol.
I will attempt to add before and after photos.
Regards Roy

Thanks, It's fun to drive. I have had to make virtually everything as everything was ripped out, suspension wise. But it has been enjoyable. Now to get it sorted and the other one out on track. That's the Endaf Owen/Rob Knox one, that one is virtually ready to go now. I just need to put in some legal windows and sort some front wheels. Oh and somewhere to sit. The engine is running an transmission sorted.
Regards Roy
Hi Roy, I’m sure you will get the handling sorted out, once you do they are great fun, I quite liked the tail hanging out on corners, but I like driving like that, not the fastest, way to do it, but more fun lol. I run a Fireblade in my one, but I had the engine mounted just 20mm off the back of the seat, only problem with that was it got rather hot in the car. Hopefully you might get some videos posted of it in action.
Hi Les and Coll,
I don't mind the back end coming out when I'm on the power but turn in oversteer on the fast corners is not pleasant. I'm intending to set it up like our Ralt, that takes the fast stuff as fast as I want to go. As I said before the fiddly stuff is ok.
I know how I used to like Imps with conventional suspension to handle but this one is basically a single seater underneath. I'm now waiting for someone to say where is the Imp in that, well it has a genuine Imp gear stick and gear knob. Nothing else. It never was an Imp, no Imps were harmed or damaged while making this.
When I bought this Dermot advertised it as a corpse, so I must have revived it a bit
Handling is now fine starting to feel the car. It doesn't seem to have any nasty traits. 2nd in class to a Radical in in amongst the Single seaters at Castle Hillclimb, Cornwall. Of to Clay Pigeon Kart track for a Sprint this weekend where I have a Radical and a Spire to contend with.
What's happened to all the pictures at the beginning of this thread, they have all disappeared. It was a valuable source of information on how to build a spaceframe and now it seems to have disappeared into icons. Is it this forum or photoshop?
I think you might mean Photobucket, and yes, it's probably down to them after they chose to charge for their hosting. Didn't ultimately do them any favours. I understand that we will more than likely be getting a new Forum, which is undergoing tests right now. Will make image uploads easier, and possibly as seemless as Facebook.
Enjoying all this spaceframe history but really want some on mine. It is the Maguire Imp No 1 and the last owner was Keith Scott, who I think, went to a great deal of trouble tracing its ownership from day one. Unfortunately the mobile number I have been given is now discontinued, can any one help me speak to Keith or have historical information on the car.
It has now been completely refurbished and brought up to the latest MSA standards by Colin Rooney and has its passport and I have done a few sprints with the car but would really like to know it's history.
Hi I'm looking for info on the car in the picture. The chassis has passed through a few different hands in the last 10 years I now have it and hope to restore it, last owner started cutting bits of spaceframe out to fit a bike engine luckily he kept all the bits! The bits of body I have for the car are not what was on the car to begin with so I'm hoping sombody might know a bit about the car.

I've just joined the forum having 'lurked' for a while. This is an absolutely fascinating thread.
My interest is the Special Saloon Imps from the 1970s, especially those in Scotland as I'm currently preparing Scottish Hillclimb Championship results for OldRacingCars.com. Many Imps and related spaceframe beasts qualified for the Top 10 runoff in the 1970s. Should I put a list up here to jog some memories?
I am just dealing with basic event results here, so no photos unfortunately. Iain Nicholson is probably the man for those.
This is a list of all the Imp-related cars quick enough to qualify for the Top 10 runoffs at Scottish championship hillclimbs during the 1970s:

Can anyone help me with these cars? I'm assuming they were 1-litre cars, but I don't know whether they were all Special Saloons or some were running in the road car or Modsports classes. I'm particularly interested to know when they started to be spaceframes and when the Maguire, Rawlson, etc cars appeared.
Were these normal Imp shells at the start of the decade and spaceframes by the end?
