Con rods trying to escape...

[chevy2]

I get quite a variety of jobs come through my place,

Heres a sump pan from a dragcar,
to be more precise from methanol funnycar that makes i'm guessing somewhere around 3000 horsepower?
at this level when stuff goes bang its a big mess,

I've got the job of trying to salvage a $1000 sump where 2 conrods tried for a sharp exit,

Sort of looks like a shotgun went off in there?
Heres the area to cutout.

And trim out all wrecked panels from inside,
a bit easier to staighten the side rails now.

Being about an inch x 3/8" they're gonna take some bashing!

Now to start welding, plenty of build up reqd to level up the inside faces which will need dressing up later,
got the pan rails pretty straight but still multiple passes of weld reqd to dress back true to get a good gasket seal to the block,
this 'little' bit of build up took 7 filler rods,
also made a new windage tray to replace the one that looks like its had a bowling ball dropped on it but forgot to take a pic of it,

not a bad start for one evenings work,
hopefully have the job finished tomorrow?

Final part on this job.
Plenty of filing and sanding to get the pan rails true and smooth after the weld buildup

Made the folded repair panel in 2mm sheet the same guage as the rest of the pan,
tacked in place with some steel clamped along the rails to minimise warpage.

Fully welded.

Also welded the seams on the inside to keep it smoother so as not to hold engine debris and easier to wash out between rounds.

Some of the various brackets that needed replacing.

The replacement windage tray made earlier with hinged trap doors for oil control.

Final pic,
one repaired sump ready to race again!

dunno how my mate Fred does it,
the very moment i put the torch down and put the kettle on he walks in!
not complaining as he took the sump with him to drop off to the owner

nice work

I saw a funny car go bang once, was standing around 30M away and it made me jump a bit.

nice looking repair though, I bet the owner was happy he didn't have to buy a new one
