would it be ok to use 91 octane on a 100 wet shot or is it bad?

 

I wouldnt do it not sure if its okay or not but I wouldnt do it.

 

As long as the cars runs on 91 octane currently with out problems you would be ok to do a 100 shot.

 

I spray 200whp on 92.

 

I just went from 92 in Hawaii to 91 in Az. I havent run the N2O yet, but will be hitting it on pump gas, as long as the tune, system and setup are good you shouldnt have too much an issue. If you get detonation, you can add a can of NOS Nitrous Octane Booster/Torco accelerator or similar, like a pint of toulene or xylene.

 

No Cats??? Headers? An afterMarket MAFS ? 100 Wet Shot of Nitrous? 91Octain fuel? Car Prolly Runs Rich allrdy. How Dose the Car RUn now as stated above how it runs ATM. stil Check the Timing . But i would Not Reccomend it

 

Not to hijack the thread, but when you say add a pint of toulene or xylene...is that for a full tank, or half tank of gas? I also heard you should add some marvel mystery oil, about 3 tablespoons?

Thanks,

 

You should be ok as long as your tune is stock and its not tuned for 92 or 93 .

 

I run 91 CA crap gas with a 100 dry. I try to put a little 106 in the tank just for good measure, but I've sprayed before on just 91, with no problems. I run the stock screened MAF though! I pinged NA on the ported maf ends. Also, I am on stock tune. I don't spray when the temp. outside is above like 95 either.
