i was told that runing 93 octane fuel was bad for the car, is this ture?

 

I've never heard of it causing any problems. I also run it on my car.

 

I have run it for the last 112,000 miles.. no problems

 

there is really no benifits in running it though as our cars are fairly low compression.... they did a test on this show I was watching yesterday they ran a truck on a dyno and tuned it to it's optimum A/F levels (changing anything would lose power) and ran both regular and premium.. it had almost exactly the same HP and torque curve either way

If you get some high compression piston heads (hwarang piston heads from hp.com) and properly tune the car you'll see much better n/a gains than you would with our 8:1s though.

 

is there any reason why your runnin or thinkin about running 93

 

purpose of going to high octane is - to avoid detonation. That's it.

Detonation can be in result of high compression ratio or high boost level.

 

As said, with proper tuning (which might include spark timing advance if you use higher octane gas) you could squeeze the last drops of your NA performance on a std. engine by advancing the spark.
However, if you raise compression, by changing the pistons (which is the expensive way, and maybe the better) or by changing the head gasket or even milling a little on your head (this last option isw not the best, and should be done only by experts and only a little).
I think REAL Korea has special gaskets to raise compression on NA engines, and as far as I remember they are not too expensive (a little less than turbo gasket)

 

i know i was asking if HE in particular had reasons to run that...meanin im not sure what mods he has or if he was just asking

 

i was just asking if it was bad all i have is an intake exhaust and headers. i was just wondering if u would do nething like in the engine timeing or with the sparkplugs.

 

No, it won't hurt anything in your engine, at the most it will hurt your wallet...
But if you get a better ECU, then you could have some mods and take advantage of that extra octanes.
