Possibly a doubled oil filter base gasket. Old gasket from the old filter stuck to the mount and new gasket on the new filter, that will create a jet of oil at high pressure to come out between them due to lack of side support.
Always check for this, I make the two filters 'kiss' to be sure the gaskets are there and they match up.

How would you ever prove that you had an oil pressure spike? Unless you were data-logging oil pressure at the moment of the failure, you are shooting in the dark. On the other hand, if you have a reason to suspect anything other than a cheap filter failing, you could always replace the oil pump or the oil pressure relief valve I guess... but if it were me, I'd wait and see if the problem ever happens with a quality filter that was installed properly.

Why are you looking for a more complex resolution to the problem? It was a cheap filter and it failed. Clean up the mess and install a Mahle filter, and I doubt you will ever have the problem again.

One of my NAs did this (my first one), the pressure regulator stuck and I had max oil pressure, blew the seal just like that and dumped a buch of oil but no fire. It was a mahle filter too. Got a tow, put in another filter and oil and the pressure was still at max. Mine was a an 85.5, and in the process I upgraded to the newer oil cooler, don't remember for sure which regulator I had, but never had a problem again. YMMV...Bruce

look at what 962Porsche says in his first reply in the below post. that would fit my scenario because there was an oil leak starting from where i was parked to the pits then the start line where i had my fire as soon as I took started my run. meaning it blew the seal when i started the car.

You guys are too quick to blame the filter – most likely too much oil pressure.
I have seen quite a few oil pressure relief valves get sticky – the stock system can put out well over 150psi if the relief valve gets stuck. Most go over 100psi when cold even with a good OPRV.
Is yours a 3 piece or one piece OPRV? (either one can get jammed but the 3 piece is more likely to get stuck).
Install a mechanical oil pressure gauge the reads up to 150 psi.

We just had to chat it up enough to keep the thread near the top until Chris had a chance to see it.
