100% correct!

 

Here's a dyno test using 104+ booster.

Cars have knock sensors so the computer will automatically pull ignition timing if it detects detonation. So don't worry about damaging the engine, but like everyone else says, stay off the boost just to be safe.

 

go to the paint shop get 2 gallons of xylene or toluene(paint thinner) and pour in your gas tank. that will raise to octane level close to 91.

 

How do u stay "out" of boost? or how do u control the amout of boost?

Im goin to buy one in 2 months so i dont know these details

 

On a stock car, you stay out of boost by shifting at 2.5K.

 

so the turbo only kicks in after 2500 rpm? is that true on the sti as well?

 

no problem, octane boost it and then prepare yourself for the most boring 300 miles ever in your car because you are going to stay out of boost but get incredible mileage

 

10 gallons of 87 + 4 gallons of 100 /14 total gallons= 90.7 octane
should be safe.

 

So, does anyone read their owners manual?

 

What would happen if you did get into boost?

 

The computer would detect detonation and retard ignition timing resulting in a loss of power, but no damage to the engine.

 

wow, that sucks.. i would just drive under no low boost till it runs down and then put some 93 in her.

 

Drain it. The dealer I bought my car from fill it up with 87 octane when I bought it. I made them drain all of it.

 

+1 The octane rating they are claming is not motor octane. I think it's called engineering octane or something like that. So you would need like 50 bottles of that stuff just to get you close to 91......I would just take it east then mix with VP 103. AND NEVER LET YOUR GIRLFRIEND CLOSE TO YOUR CAR AGAIN!!! She's suppose to be at home folding your laundry barefoot and pregnant anyway! LOL
