Got a track related question? I'll try to answer.

Okay, seriously, don't redline. If you do, roll onto the throttle slowly after you shift.

That has crossed my mind many times. I've always debated on getting a CR instead.

If we can confirm that this is definitely the root cause of these engine failures, and Toyota/Subaru is unwilling to band-aid it with an ECU update, then there's really no point in keeping the car.

Competitiveness really depends on who your local competition is.

Thanks for your advice. I'm very humbly returning to racing after a several year hiatus, more forgiving sounds like exactly what I need. Could you explain briefly why a smaller tire is faster?

That... remains to be seen. I sincerely hope they do, cuz without, the platform is doomed. The majority of the track regulars have already had the issue.

Great, that's going to artificially increase the demand/price of the S2k even more.

Wonder if the 91 octane gas (highest available in Cali) has anything to do with it. Maybe it's causing more detonation compared to 93?

I'm having issues on track even with 93.

Our final failure happened while on 100 octane unleaded... we put it in as a precaution since it was pretty warm.

I'm sure this is true unless they come out with a permanent fix. I really hope the ECU flash fixes it or i'm guessing 1st year models will be worthless.

Good thing seems like it's a relatively new problem that hopefully is under investigation.

How's fuel starvation?

Can't say the same for those running E85 and/or aftermarket tunes and fuel pumps.

Definitely a no-no with FI.

I've been resistant to go with a tune for warranty reasons but it kinda seems to be the best step so far

That's what made me do it!

Both ways seem to suck. Basically own a gimp sports car till it's fixed or get a tune and deal with warranty excuses from dealerships down the road.

Both ways you have to think if your car will have long term effects from damage that possibly have already occurred

Thanks Obama

you injector seal was already bad at this point adding octane after the seal failure does nothing to protect the engine.

It went bad on a day where we were running roughly a 1:1 mix of 91 and 100, so I'm willing to say no correlation between octane and DI seal failure
