2012 STU Discussion
C. The air intake system up to, but not including, the engine inlet may be modified or replaced. The engine inlet is the throttle body, carburetor, compressor inlet, or intake manifold, whichever comes first. The existing structure of the car may not be modified for the passage of ducting from the air cleaner to the engine inlet. Holes may be drilled for mounting. Emissions or engine management components in the air intake system, such as a PCV valve, or mass airflow sensor, may not be removed, modified, or replaced, and must retain their original function along the flow path.
It is up to the turbo inlet on turbocharged cars. So basically you can change the intake filter and the intake pipe as long as the MAS isn't modified or moved. Intercooler pipes and core have to remain stock.

From: Why do they always call the Evo the Dark Side?
Hey Guys,
From a west coast perspective, Sean and Josh were really fast right out of the box, and I bet Tristian in his M3 will be top 10 in the slalom biased course. Jake Deihl can throw in a fast day too. Although I think my codriver will do very well again, his rally Evo 7 was why I bought mine in '03. I hope to be back up to speed next year. Looking forward to seeing everyone again.

Sean, Josh, Tristian, Jake and Wolfgang all in the trophies after day 1.
Never in a million years would I have thought an m3 would stand a chance... but I know Tristan and he's a very talented driver. To think, just 2 years ago he was running in our region's novice class. What's crazy is I get to witness the battle between Tristan, Josh, and Sean almost every event. Congrats to all who ran!

Well first of all congratulations to Tristan, as those were great runs on both sides! Also, congratulations to the other Evo guys who managed to get into the trophies.
I needed a different setup to keep up with the top guys. I've been running the same setup since Toledo but it was rough on the East course and completely useless on the West. My car was far too tight handling-wise on both sides which is not what you wanted, especially on the West.
Also, not to take anything away from Tristan in the M3 as he laid down great runs, but the courses definitely favored something that wasn't a boost buggy, especially on the West course. There weren't any sections where we could lay power down out of a corner as it was all about maintaining momentum which isn't our best ability.
The winners in STX and STC out-rawed the whole field in STU along with the top 2 in STR, and the 3rd position finished behind Tristan by less than 0.1. The first non-M3 in STU would have finished 9th in STR.
If this is indicative of the other National tour events (I haven't followed them much) I expect we will be getting a PAX adjustment. The Nationals courses this year though definitely got the better of the Evos and the STI's.
For me, I will need to find a way to make my Evo much looser on the Lincoln surface before I can keep up with the top guys.
Again, congratulations to everyone!

Good seeing everyone out there, and seeing all 3 brands of cars in the mix.
On the less speed maintenance east course, my Evo with Wolfgang driving was second quickest behind Josh's STi, so that was a more balanced course. Grippy concrete helps out the M3s too. Tristan has been getting faster since he got his Motons, so it takes an Evo biased course to beat him locally!
He's come a long way since a year ago, when his car was stockish:

Bump for a new fastrack - notably this tech bulletin:

Who's removing a bunch of clamps this weekend?

Aftermarket T-bar clamps in the induction system are considered higher performance than OE parts and are therefore not allowed by 13.0. NOTE: The additional clamping force may serve to withstand the higher boost pressures which can be developed through Street Touring allowances. (#8673)
