I need to "trim" the center tunnel a little so my pedals can fit better. How much of a structural factor is it to the car? see pics.

Looks to me like it would be a lot easier if you just remove that extra bit of pedal.

(IMG:http://www.914world.com/bbs2/html/emoticons/agree.gif) Just do some trimming on the pedal...

From the pic it looks like it wont take too much.

Boxing the pedal area is what I am going to do. I am making it easily maintainable.

There will be a box, somewhat. The pedals will drop in on one piece and bolted to the floor. Then, an aluminum cover with Dzus fasteners will cover it up and prevent debris from entering the cockpit. It will be fully sealed with rubber (hehehe), to prevent water from entering as well.

Removing the extra stuff on the pedal won't happen. It's cast, and I need it for a foot support and to run the throttle cable.

Tilton pedals, from ebay with master cylinders, $225! CNC brand gas pedal, $35 from Pitstopusa.com.

I think the Tilton pedals are usually $250 w/o m/c's.

Metal plate - $2 from metal shop.

the tunnel is part of the structure, but since you have a cage, I'd think it wouldn't suffer much if you make some minor cuts in it

do you want to move it to the right more than you have in your pic?

hard to judge from the pics, but maybe it's easier to modify the throttle pedal?
lengthen it upward?

nice car btw... got some more info/pics?

You got yourself a cage, you'll be fine.

Im planning on having the same setup for my pedals...

How much did it all cost you?

Thanks

Terrance - have you moved your drivers seat over a bit to line up with the pedals better? Just wondering - I have a Tilton triple pedal setup in mine in just about the same area, and I moved my drivers seat over about 1-1/2" inboard and still felt I had to "reach over" a little with my left foot to push the clutch. With the tube car, I am going to move the pedals to the left a bit (where that other structural piece is) so I can line up with the clutch better.

I have a really heavy clutch in the car and lining straight up with the pedal would be a real advantage for me. Just wondering what you're thoughts/experience is with having the pedals mounted there.

Terrance,

I thought you were a CSOB (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

Here's another Tilton in 914

Nice BTW...

I cut the top of my tunnel out (to put stuff in there, weld clutch tube, kill rust, etc.) and without most of the tunnel the floor still seems plenty strong. (I'll be welding the top back on) I still wouldn't run a car without one, but taking a little chunk out should be fine.

byndbad914 - I will definately have to move the seat over more. Since it's a race car, I can do some drilling. Most porsches are offset for some reason. I was thinking of moving the pedals to the left, but it won't work for me, because the M/C's are so long, I have to cut into the firewall and mount it farther forward.


Neo - I saw those pics, thanks. I wonder how much of the firewall was cut to fit? I had to chop mine up to do make clearance for the M/C's.

Overall, I did this so I can have nice solid pedals to use, and good M/C's. the gas pedal is dope. Soooo smooth, and not wobbly. I have to cut the tunnel, and mount the pedal a little more crooked to make some clearance for heel-toe action, and also make sure I dont' step on 2 pedals at the same time.

I figured it out. Tilton makes shorter master cylinders, which will save me almost 2". Which means, I can move the pedals even farther forward, so I can tilt my seat more, and sit even lower in the car.

Thats what I did too, Terrance. I think the M/Cs are Tilton 75 series, or something like that. I built a box in the floor so I could move them farther forward. I managed to get the seat a bit lower too. I also moved the seat over so that it sits right up against the tunnel. Pretty straight shot at the pedals that way....

Here are a few pics:

Here's a somewhat lame shot of the pedal box from the outside, but it might give the idea...
