"Racing gas" in a Boxster?

[Lil bastard]

I ran a tank of 100 octane race gas when a local station had it on sale for $3.879 in order to sell it off and drain their tank so they could and use it in the coming winter for Kerosene (they do this every year).

The car ran great, smoother, most likely due to the fuel being dryer (race gas doesn't absorb as much water). It was likely making a couple more ponies, but not like the Second Coming or anything.

IMHO, if it's not competitively priced with street gas, it's waste of money.

guys,

thanks for the help.
can you give me some advice on what brand / model to get when I look for:

- pads - sounds like pagid is the way to go - what style
- brake fluid
- seats - safe and reasonably priced
- harness
- is that hardtop structural? or is it better to get a roll-bar extension such as the brey-krause?
- you guys using HANS?

thanks

my car's basically been a street queen - most mods from prior owner. I've done a number of auto-x / track days / high performance racing schools over the years but never had the boxster on the track...somewhat ironic.

"I wouldn't use a tankful of 100 Octane on any car unless you have special fuel/timing mapping for it."

I dont know, I probably would have tried it if I had a stock ECU just to try it out, such is my nature. In my case I got in touch with the folks that did the remapping of my ECU and asked them if the program would respond to higher ocatane fuel.

They said it should, and when I put in the racing fuel, the car did seem to run a little differently, seemed a little quicker with the butt dyno, and gurggled more when letting off the gas. When I ran it on the dyno, it looks like it picked up about 5hp with the racing fuel, so in my case it seemed like it was doing something.

Yes the car will run better and will have a slight gain in HP. But you don't need a full tank of 100 Octane to get this. All you need is a mixture of 100 Octane and 91 to equal 94-95 Octane. Your fuel mapping will max out at 95 Octane.

Nice car. Are you sure you want to ruin it by taking it to the track

There are a lot of valid options for equipment. This is just what I use:

Pads - I use Pagid Black (the race version, RS14), but they are true track pads meaning they squeal loudly and need to be warmed up. Orange make less noise and need less warm up and are still very good. Lots of other options and opinions.

Brake fluid - I use ATE type 200/super blue. Another good choice is Motul. Motul is higher temp, but should be flushed more frequently.

Seats - I have Cobra Suzuka S, but I've seen lots of people with Sparco Evos. It's worth it to go to a retailer and to sit in them to see what fits you best. The Boxster is tight, so fitment might be an issue. Get one with a FIA label, not a cheap knock off.

Harnesses - I have one Sparco and one Schroth. Again, lots of good choices. Just be sure to get a 6 pt harness as there is no reason not to. Installing is actually easier since they use the lap belt bolts. Be sure they are dated.

Hardtop - I think I read the stock hardtop adds some structural rigidity, but I wouldn't count on it to protect you in a roll over. Get a BK rollbar extension. Used it's $300 or so. I had one before I installed my cage.

HANS - I don't have one, yet. Honestly, not many DE folks do. I plan on it though.
