Bretts right on here: as an FYI I ran my Avant for the second time all
winter. The "hiss" under the hood is in the exact spot Brett mentions. My hose has
a leak (there is actually a splice in it.) I'll take a photo and short vid
of it. Squeeze your finger in the slot and the hiss was lessened.

I've been scolded: Never go for full boost on 87 octane especially chipped.

You'd need Z rated tires and a straight longer than what's available at most
tracks to accomplish this. Therefore, it would be an outlawed & illegal run
to do so. My suggestion would be KS, MT,UT, NV or TX were those FLAT / wide
DIVIDED open interstates could support that kind of sustained speed. Down hill
would help too. No track event would encourage a top speed run PERIOD. Unless
you can get onto some NASCAR superspeedway high-banked oval you'll never get
there...and probably wreck trying to.
Brett's done ~120 @ the Glenn: in that same area: (as a reference ONLY)
modded S4 (93-94 etc) have been radared at 128 - 131. Vette Z-06 '02 : 130 PLUS.
'03 Chevy Impalla 104. Cup Car Porsches GTC2&3, push 140 MPH and that area is
slightly uphill too.
