Race gas good or bad?

I'm going to go to the drag strip on friday and I know they sell race fuel there but was wondering if it would harm the engine. I don't know what the octane rating is but if it helps it's Famoso Raceway in Bakersfield, CA. Any input would be helpful. BTW I know Subarus are not made for drag racing but there's no road courses that I know of and I want ot see what this car is capable of in terms of 0-60, 1/8, and 1/4 mile.

Your pretty much right.
Most likely the gas there is leaded which is bad for your cats and injectors.

My turbo's fixed and a lot better =)

Thanks for the info, I think I'll just go with 91 Premium that I can get anywhere. You mention 93 where do you get that?

Race gas is great, if you're tuned for it. For your car, go with whatever your premium is. You won't really benefit from the higher octane the way your car sits right now.

My car is well, it's like 10 lbs of shit in a 5 lb bag...

C16 will net you Large gains on the Dyno with supporting mods when Tuned for it, but if not don't bother throwing your money on 8 bucks a gallon.. Even the $5 turbo Blue is a waste in our cars.. A more cost efficient option is Pump + Meth Injection.. With tuning this combination eliminates the need for Race / Street Gas..

91? I don't think I have ever seen 91 octane, around here in CT I have just seen 87, 89, 93, and maybe 92 once.

WE used to have 94 octane, I wish they bring that back. Some stations here sell 100 octane and up, but you got to know where it is kinda thing.

I finally got a chance to post my times! I'm actually kind of dissapointed but here it is 14.6@92mph. I know I could've done better but it was like a hundred degrees and I was runnin the stock Potenza RE92A's. Any way next time it won't be bone stock. Let me know what you guys think.

was that your first time at a track, b/c if it was that's not too horrorible. did you adjust your tire pressure, remove spare or anything. also letting your car sit as long as possible between runs and possibly icing your intercooler would also help a considerable amount. i bet you could easily shave .5 off your et just by doing that stuff and practicing launching. although there have been several people running as low as 13.6-13.8 bone stock, atleast from what i've seen. hey goodluck man

Garage
14.5 is the usual bone stock for a WRX. Especially if it was hot outside (has less to do with the intercooler than with the air intace) those numbers are pretty good. What were your 60' times? That's really where you can see how good a job you did.
