Hi All,

I have just picked up a floor mounted peddle box one of the universal ones

Any one tryied to fit one to a manta before? its nice as its got the hydrolic clutch.

I am going to use the small master for the front and the big one for the back (little master more presure but more movment)

Cheers

That'll be fun.

Hope you have short legs.

The master cyls end up through the floor!

Really need pendant one or pull-type.

Been through all this for a customer project................

That sounds familiar Nat!!

They are a nice item Stagcar but as far as I remember from numerous chats on the subject they are a bit of a struggle to fit without some fettleing to body work, but if there is anything you need to know about that side of things then Retro Power is your man.:thumbup

Yea sorry for sounding a bit negative!

I measured up as I have those floor mount boxes laying around, but I couldn't get one in and still keep a sensible seating position. To be honest the pedal angles are crap for std seats (recaros etc), though its easy enough to cut and reangle the pedals and reweld.

The big problem is getting the pedals in the right place, while keeping room for your feet to actually operate them!! If you place them in the right spot, you'll find the master cyls go though the angled part of the floorpan where it kicks up to the bulkhead seam.

This in itself isn't an issue, but the chassis rail is right where your clutch and left brake cylinders need to be, so you can't just box the floor out!

I know all this as I looked into putting electric assisted brakes into a manta that we are building next year, and there was just no way I could get the electric assist unit in, then I measured further and discovered I couldn't even get the normal bias box in!!

The answer is to go for a pull type box OR a rear mount cylinder push type box. Problem with the former is 1) they are not really available off the shelf other than from AP as you need trunnion mount cylinders, and the AP box is £1100! 2) Your feet are raised on top of the cylinders, though this isn't too bad, though your toes are right under the dash!

The rear mount push type will work, but then your feet are raised by the height of the cylinders, which even diagonal mounted need around 50mm in reality, and thats with tight elbow connections on the fill ports. The answer there is to mount them into the floor, but the jacking point is in the way............

Without going into all the details that cost me a day's head scratching while earning no pennies, you'd need to re-design the complete manta floor and jacking outrigger...............next year I should be able to show you!

Personally in your position I'd swap it for a pendulum mounted box, such as the one that rally design sell specifically for the manta. If you really want a hydraulic clutch then use a mk1/2 escort triple cylinder box and mod it to fit, it puts the cylinders inside the car so its pretty neat, I just run -4 bulkhead fittings (7/16" unf) though the top of the bulkhead and pipe up to a ressy in the engine bay to get a decent gravity feed.

Thanks for the good response it looks like a bit of pain to fit like you say mostly due to the chassis being in the way behind the bulkhead any way i will try few places and see what happens thinking i may raise the peddle box of the floor by 3 inches so the masters can sit a bit further back? and may be a bit of help from mr large hammer any way i will let you know what happens failing that i will go for the swap

Thanks again for your help

I ran that pedal box in my car all last year, only problem really was having to mount the seat further back, but that in turn helped with the weight ditribution, I have just swapped it out for a reversed cylinder type from optimum balance. Have a look in the motorsport thread in the `God I hate re-build time` 1&2 threads, it will show both types fitted :thumbup

There is next to no space for a conventional type pedal box with hydraulic clutch.

It`s in here somewhere!

I have just been through the entire thred Now that's what i call a rebuild i real quality job to mate.

Amazing amount of work there car looks the dogs hanging bits.:thumbup

I see you also mounted it a bit higher in the car and went for a slightly raised floor to rest the heals on

That's the sort of thing i was thinking of i will tack it in weekend and see how it all lines up or not as the case may be!

one good thing is my car will also not have any carpets of trim so thats one less thing to worry about all so that means i don't mind getting the grinder out again<_<

Many thnanks

I am doing much the same as above, but sinking the whole lot into the floor and (as the whole floor is being replaced anyway) refabricating the outrigger, and turning the whole outrigger assembly into part of the housing for the pedal box, if that makes sense..........

Ps, re. the conventional type pedal box, I've never actually fitted a rally design one I must admit, as I usually make my own, but I have converted to bias bar and hydraulic clutch with the conventional layout and it DOES all fit, on the other hand, for a rally car, the access is not really "service friendly" I will admit. You have to take the cylinders off to get at the fill port unions!

PS PS

Looking at those pics Spewy, it shows EXACTLY the problem as I measured it. If you extended that cutout you've made in the floor forward by the 150mm you'd need the get the cylinders in with the type of box shown at the top of the thread then there would be no room for the chassis rail at all!

I think there might be some confusion here, the cut out in the floor is not for the type of box shown at the top of the thread, it is for the reversed cylinder type here.

The cylinders are mounted under the alloy plate and you don`t have to move your seat too far back.

I have just changed from this set-up

which is the pedal box shown above using a false floor.
