i hve done some search about it and i cant really find the answer.

my goal is to get 350whp with the mods needed on my search like

both 272 cams,gas pump,boost control,intake,fmic w/ piping,maybe i forget

some..


im from canada in a state where the only available gas is 91oct..

is it a problem... except some loss of power who less oct gas can brg..

 

It isnt a problem however you arent going to be able to make as much power as you would with 93. The higher the octane the less prone to knock it is so therefore you are able to run more timing and extract more power.

Just make sure to get a good tune for the car and you shouldnt have any issues.

 

I was making 330whp on 91oct with HKS 272s, Intake, TBE, fuel pump, metal IX BOV and boost controller as a point of reference.

 

yor goal definitely looks possible with your setup. you'll just run a slightly less agressive tune/boost with 91 and lose a few ponies.

 

I have to deal with 90 oct where I live..... all I can say is two words ...... meth injection.... if your not comfortable with this you can always run some torco or similar additive, I think a 1/3rd bottle of torco with a full tank will give you ~93 oct

 

thats wat im planning..meth

Definitely possible with an IX on 91 with those mods.

 

Just put it on a dynojet, it will make it no problem.

 

^^then he might as well just load a log into VDR and play with the conditions until it gets there
