Two words: Destructive Testing.
Before I swapped out my engine, I had my original GSL-SE 13b with 97k miles that I had run to 83k or so a few times at WOT on the race track with absolutely no issues. I have found that engine to be pretty much bulletproof. I would not do it though unless you plan on swapping your engine.

but yes, the new airbox/intake setup is in the planning stage, i want to run the comp setup, but my radiator won't move over far enough to do it
exhaust is going to get redone too, the presilencers lasted 9 half *** laps. i also want to find the right header length on the dyno
i'm running carbon seals, on a balanced rotating assembly, it goes to 11

the stock box should be plenty for any stock 12A, actually, if the P port is happy with it to 6500.

As far as exhaust goes, on a PP it's allllllll about the length of the primaries, they need to be collected at the 7.5" inch mark.
I'll take a picture of my Downing 13B PP header when I have a chance this weekend and PM you the pics, I also have a Downing Header made for my 12A Monster Port for a tube chassis car that I'm copying to fit into my car, the car the my Monster port is currently in. The primaries and collector is actually bigger on the MP header than the PP header, BION. Like I said, I'll take pics.
On any periph, I stay with Ceramics. But I know, I know.. $$$$$..

yeah pics would be great! i just have RB headers now, i built mine based on the competition book, so i wanted to go with a 90" header, although its more like 72" cause i didn't tell the fab guy IT MUST BE HERE.
but since it melted, system 3.0 is in the planning stages, i was going to make it adjustable length, just so i could go to the dyno and get it right.

I think maybe I need to take this race pressure regulator out and swap it for a stock one..

interesting, that first one almost looks like a turbo manifold

The reason for the loop is for length, increases torque. Longer the length after the collector before the muffler the more torque, and same for the primaries. Longer the primaries, the less torque you make which is exactly why I don't like RB's exhaust headers. Or the long primary system in general, on a side port engine it works wonders. But on out big port engines it hurts low end performance, which we do need.
