Just purchased a turbo from Chicago and the owner used to run 94octane. Now the car is in California and anything above 91octane is hard to come by.
What is the best way to boost the 91octane? They sell the octane booster bottles here, should I use those with every fill-up or is that bad?
Any other ideas?
Thanks!

 

Do not use octane boost. Purchase 100 octane street blaze at a local gas station or race gas in a 5, 10, 25 or 500 gallon can.

 

we do not have 94 octane in Chicago.. its 93.
why even bother? every P car sold meets cali emission standards...
at worse the car will put some timing as usual....

 

Don't worry, be happy. Just use the 91-octane gas. The car has monster power
no matter what. It would take very careful timing devices to detect the difference
in performance. It's not something you'd ever notice when you blast onto an on-ramp
and get to 100mph before you know it, whether you might have been at 100.8 mph
instead.You can get yourself arrested *just* as quickly with 91... Relax. Enjoy life.

 

plue octane booster kills spark plugs. at least all the ones I have used.

 

Most OTC boosters barely adjust the octane (like .1-.2) so stick with the advice above...

 

uur-

Watt and Marconi, 76 station, 100 at the pump. 50/50 with 91 and you'll be running ~96 octane.

DO i have to switch over to a different map/flash in order to run above 93octane? Or can I just do the 50/50 mix or even 100 octane as is?

 

You can run any unleaded gas at 91-octane or better. In fact, I'm pretty sure
you could drive across the country and back using only 87-octane as long as
you drove like a commuter, and didn't do it in 0-100mph blasts... In other words
if you're out of gas somewhere you can only get 87-octane, feel free to use enough
to get you to better.

The stock program has a range it will accept/adjust for, and you will get all it
can give with 93-octane or so. If you want more power out of much better gas,
then you want a reflash, but be warned that a flash that extracts the most out
of 100-octane gas (for instance) will *not* be able to run safely with 91-octane.

 

Didn't you just have a 996 turbo? :-) Does your new one have a ECU map or is it stock? If stock, then can run 91 no problem.

 

get a water/meth injection and be done with it , it will be like running race gas every time, without the cost.

 

octane boost for my experience reduce power, slow down the burning process. Result is no knocking but power loss...isnt efficient...

 

This in my opinion is the best thing that you can do for CA 91 octane cars!

I feel bad for all you CA owners .

 

I did have a 996tt, sold it, bought a cl55, sold it and bought a much lower mileage 996tt with a gt610 kit on it. Not a stock ECU, has EvomsIT I believe.

 

Ah sounds like a good one! I am the guy who bought your JICs from your old car! Finally got them installed and really like them!
