motor is a 2000 JDM B18C-R in an EG-- stock internals, P28 mugen chipped ECU...im running obd1 if that matters...trackin on wednesday and want to fill up with 100+ octane instead of the cheap 91 here in CA.....any possible problems i could run into by doing this?....02 sensor?...thanks

 

You shouldn't have any problems as long as it's unleaded. Only leaded gas will cause a problem with the O2.

 

... and your cat converter

 

thats what im sayin....my cat will get trashed

 

Only if you use leaded gas. 100 octane unleaded should be fine.

 

you WILL hurt your wallet

 

f*** it 91 does the job just fine....just wanted to be a baller for a tank

thats right anyways, if your car is tuned to 91 then 100 aint really gonna do much at all...

thanx for savin me the $$$

 

Well where are you going to buy the gas. sometimes you can find 100 for $3.50 a gallon or so maybe cheaper can't remember and gas these days is $2.30 a gallon not that much more, but in your setup you really don't need it unless you are pinging which I have seen with the Mugen tune, but you may not be.

 

It also has a slower burn rate which can lead to carbonized combustion chamber and higher emissions. If your not pinging you probably wont be able to tell the difference anyway.

 

In some cases this is not a good thing too high of an octane will not burn properly and actually make your car slower than with a lower octane gas.

 

ATTENTION ALL RICERS: RUNNING HIGHER OCTANE WILL MAKE LESS POWER!

Assuming there is no detonation, lower octane = higher power. Running 100 octane when you aren't tuned for it is retarded. So is buying race gas to be a baller.

Also, while we're on the topic of stupid ricer myths, running leaded gas for a tank, or two, or even for a few years... will do just about nothing to your O2 sensor or cat. If anything does happen, it will take a long long time.

 

It wont do anything unless you advance your timing like a crazyt monkey

 

you can run 100 octane as long as you want you wont hurt your motor at all in fact is better for the motor.<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by HUBB &raquo;</TD></TR><TR><TD CLASS="quote">motor is a 2000 JDM B18C-R in an EG-- stock internals, P28 mugen chipped ECU...im running obd1 if that matters...trackin on wednesday and want to fill up with 100+ octane instead of the cheap 91 here in CA.....any possible problems i could run into by doing this?....02 sensor?...thanks</TD></TR></TABLE>

 

becareful your going to make alot more power

haha MD people.... and no it wont unless the engine requires it for /timing/compression. other then that, NO!

 

hahaha...vtech

 

geez I hate that

 

read my sig

<FONT COLOR="red"><FONT SIZE="4">OCTANE DOES NOT EQUAL HORSEPOWER!!!</FONT></FONT>

the more octane you have the slower the gas burns
what does that equal......LESS HORSEPOWER

you want to run the lowest octane that your car will allow without pinging for best performance.....PERIOD!

lower octane doesnt mean more power. if that was true, stock hondas would be putting out the most power with 87 octane gas. 87 octane doesnt have the same controlled burn as 89, or 91. 87 has one initial large blast, giving you only a fraction of a second of burning. 91 on the other hand burns slightly slower, more complete, for a smoother burn resulting in more power.
if you are running a higher compression, say 11:1, and you retard your spark, you will gain hp from the gas because it is less likely to detonate. that is the greatest advantage of blue gas (100 octane). it can actually benefit an engine which has compression over 10:1 and has been tuned to take advantage of the fuels detonation point.

and your second statement is false. ive actually ran av gas (113 octane, airplane fuel) for 10,000 miles when an o2 sensor gave out. the tiny platinum sensor on the inside of the metal tip gets coated with lead and loses its ability to read the exhaust gas. dont know the effects of it on the cat...no one i know actually has one (cat. converter).

Why do you think higher octane gas burns slower? Less horsepower huh? Can you point me towards some information on this?

Did you read my post? I said "Assuming there is no detonation, lower octane = higher power." Which means "Assuming there is no detonation, lower octane = higher power." So yes Hondas from the factory that do not detonate on 87 make more power on 87 than 93, or 110, or 117 The same is true for any car.
Your response was that if a car is tuned for higher octane and you run lower it will make less power, NO ****, that's why I said "Assuming there is no detonation, lower octane = higher power." OK? Get it yet?

Also, because you drove your car for two years on leaded, how do you know that's what killed the O2 sensor? Do O2 sensors ever die regardless of octane? I know people who have run 117 consistently for 2 years without problems.

How do figure that? What's the difference with the gas besides it's ability to resist detonation?
