I have a vortech supercharged 350z in dominican repuiblic and my car is ending in 12.1 afr i want to know if its ok like my tuner said or is to lean.. I have ling tube header and some adds on... Here fuel have like 87 octane and he said for a not turbo car is ok..sorry for the bad english...

 

it's better if your AFR is set below 12..

 

You would benefit extremely from meth injection.

 

I'd be scared to tune any boosted car with 87 in the tank. Sure, a little more rich would be better up top though.

 

You fuel octane is worse than you A/F ratio. I don't know at what psi you are at but 87oct would require pretty retarded timing. As long as the timing is conservative it's not an issue. As deanfootlong stated, meth would make a pretty big difference in your car.

 

stock 350z's aren't even meant to be driven on 87 octane, nevermind a supercharged one.. Guess you could custom tune for 87 though..

 

87 oct isn't really a problem at low boost levels...it just wont be as powerful a 93oct setup.

 

Ok thanks i will put a meth system to my car to reduce the risk...

 

...or octane booster.

 

Can you fill up at the dragstrip?

 

dont understand that????

 

I do not think there is a drag strip in D.R.
but check with your tuner as you should be at 14.7 A/F at idle
and thru a slow pull up to 4k or so but 12 A/F is good at full boost and near 6 to 7 k Timing advance is the factor that will break your motor.

As stated previously 87 octane is no good the only place in D.R to get better gas is at the local airport.

Aviation gas is a higher octane fuel but burns dryer and not designed for high rpms but in your case much better that 87 if you use both meth injection and av gas along with the proper tune you will see a night and day difference.

By the way what type of tuning system is you tuner using?

 

Curious what kind of power you make on 87 octane?

 

More curious to know if there is a single well paved road in the DR worth driving on

The roads and driving skills I witnessed there were similar to those in India.

 

 

The dominican republic is GIGANTIC. It really depends where you go. I've never been there, but have a friend that lived there for a few years and the pics he's shown me look very nice.

 

here we can use vp but one gallon is 20us to much for me normal gas is 4.32us.. last time i tuned i have 340whp with 87octane and 20"wheels.. here we have beatuful places and is very fun to be..we can race anywhere...

 

we have good roads here...it depend of where yo go like somene here sais..but last week i put my car in 245 kph with any risk in a road here..its fun to dirve here but have some places that streets are very bad and have many bumps...

 

here we have a drag strip and have cars in 8 and 9 seconds because tany perdormance like to race with us and its good to see how an slr maclaren mercedes use that gas..jejejejeje and wer have almost all luxury cars here and use that gas...

 

^^^^ De que parte de la Republica eres?
