Default 2008 Bonneville 100

They held the 2008 Bonneville 100 last weekend. Three 928s made the trip out.
Matt was there with his 88 S4, Tim and Cheryl ran the Beast, and Rich and I were
there with my 90 S4. Cheryl was driving this time, and got a 2nd place in a tough
130 class, with a 130.022 mph average over the 101.6 mile course. Matt finished
6th in the same class with a 129.920 mph average (very good for a solo run).

We weren't as fortunate. We had signed up for the 170 class with a 200 mph tech
(unlimited in the time trap), but the car split the MAF boot practice morning. Rich
and I drove out the Motorsport SLC and pick one up around 11 PM (thanks Garrity
and Dave), but got back too late to try and install it and retune the car. Rich got a
ride with Paul M, in his Z06, running the 155 class. They finished 4th with a 154.931
mph average.

The next ORR event is August at the Pony Express 130. I'll be there again, with
Rich navigating. Hopefully we'll get in a good run.


1 Cheryl and Tim approaching the Finish Line


2 Matt leaving the Starting Line


3 My car at Tech


4 Highway 93A from my car practice morning


5 The offending boot


6 Paul's Z06 approaching the Starting Grid


Thanks Rich and Paul for all your help, especially getting the car running again for
the drive home on Sunday.

George,
What caused the split MAF boot? Any ideas?

That's really too bad George. I hope you get to run next time. Damn rubber bits!

18 year old rubber part under 14.5 psi boost?

Thanks Andrew, I sure hope things go better at the Pony. It's very disappointing
spending a year and lot's of time and money getting the car ready, then missing
the race because of a $20 part

That would do it another part on the LONG list of what should be replaced for a blow through system.

That really is too bad!

couldnt you just duct tape it and then run in a lower class or run it as is? (with no boost)
Im sure you could go 155mph for as long as you wanted in the S4!

Sorry to hear it. At least it was ALOT less expensive than last years "fix"
Maybe it's time to visit the "928 shrine" before the next run.

Mark, I've run 145 avg with it stock, and figure I could do 150 without much trouble,
but I doubt I could have driven this car as it is at a 155 mph avg. I'd have to retune it
for NA, which might not work too well with 42 lb-hr injectors....

Yes George you would need a sparkplug it the tailpipe, the afterburner would have been good for 20 MPH
