Completely silly idea for a sump guard?
Right, may be a really idiotic idea, but having been driving the indy much more recently, im all to familiar with the ground clearance and im always
worried about peircing the sump,
so i have been looking at sump guards, feeling i would need a reasonable thickness of metal to protect the underside, so how about wooden plank
running underneath the car, think its done in single seater race cars?
is it a really silly idea, would it just get ripped off?
feel free to giggle and point.

Done this before..............
UNDERSTEER is when you hit the wall with the front of the car.
OVERSTEER is when you hit the wall with the rear of the car.
HORSEPOWER is how fast you hit the wall.
TORQUE is how far you take the wall with you.

Found putting a sump guard on mine made it so low I couldn't then reverse up my drive....
Took it off and bought a short sump kit.
Scot's do it better in Kilts.

I made a 2mm ali plate that curved up the front of the sump and stuck it to the sump with a 6mm layer of high temp silicone sealer.

Monocoque single seaters tend to have a plank fitted to the underside that is a sacrificial barrier to prevent the actual monocoque from getting
grounded out and ruined.
Fitment of a plank is mandatory in some formula's, including F1.
I can't remember the name of the material, but it's a very strong and lightweight version of plywood IIRC.
Would a plastic tea tray do the trick? might melt a bit, but then just replace it.

Mount the numberplate low down at the front so it grounds at the same level as the sump, when it catches, brake quick  .
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Does the front suspension not droop when you apply the brakes, therefore loosing ground clearence?

Yeah, I always approach the speed bumps and get all my braking done before I reach them. I then accelerate over the bump to raise the nose. Rear
clearance isn't my problem, it's the 3" clearance under the sump.
One thing I was planning to do is to mount a couple of soft wood "skis" either side of the sump with a ramp at the front and with the skis
just proud of the sump by maybe 5mm. This won't guard against something like a big stone which might go between the skis but will help lift the
sump over a speed bump or cushion. The obvious place to mount the wood is on the chassis tubes either side of the sump. I might also have a piece of
wood across the front of sump between the two skis to protect the sump a little from the large stone I mentioned at the start.
But hey, if the sump gets clobbered then just shut off the engine and call the breakdown recovery truck. Hopefully the crank won't get any
damage and you'd be unlucky to get swarf in the engine. Don't let worrying about stuff like this deprive you of time on the road having
fun!

There is a chance if you stuff it the wood will break and could enter the cockpit. ie: snap in half and come through aluminium floor.
Just a thought. Metal would either save your sump or dent or bend but not shatter

2mm ally supported by a frame around the sump would work..
Steel would make fun sparks though

Jabwok is what is used in F1. Some type of composite material but God knows where you can get it from.

In fact, it's called Jabroc. It's laminated beech wood. No idea where you'd get it from either, though...

We use jabroc at work, and also a similar product called micarta, just found a web page to make your own, locost style. Not sure how suitable
polyester resin would be, but the proper stuff we have at work, would be perfect.
