Looking for the best octane booster to run with the arrow tuner

[FSTENUF]

OK now that the tuner from Arrow is out and we are all loading them into are Gen V's. Can anyone tell me the best and most dependable octane boost on the market today? Getting 93 octane here is not a problem however out on the open road unless you have a Sunoco locater in your GPS what do you do? With 93 being the min dose anyone know how hot we can go? To much snow and to much time on my hands today, Thanks

[Viktimize]

If you're talking about those little 1litre bottles you pour in your gas tank, then it is a waste of money unless you plan to fill half your tank with it.

[KB Viper]

torco seems to be a popular choice

[plumcrazy]

what octane will it be tuned for is the question

[venomous08]

It's probably like the gen4 so 95 was what it's developed for and 93 is min.


I run Torco to get mine up to par since we only have 91 available at the pump in OK.

[KB Viper]

Mark from woodhouse said they did all the testing on 91 and it runs fine with it. he suggested high octane gas or booster if you are beating on the car when its hot out.

[LS6M]

Ive used the nos brand on my previous turbo viper, that was tuned on 91, for safety.

Dan Cragin at SPT always tells me to avoid additives, they will ultimately gum up valves or injectors or both??

You've got 93 at the pump, out here in the west only have 91 so we've got to mix with 100.

You viper will run fine on 91 with that controller, it will just pull timing back on 91.

If your tracking your viper, I'll assume the Arrow ECU, just like the G4 venom, wants 93 but runs best on 95. Mix 91 or 93 with unleaded race fuel, 98 or 100 octane, and get the mix to 95. Also, best to use fuel cans and go 2-3 gallons at a time to mix them both. good luck, Mike

Thanks for the info.

Fuck the "octane booster" crap...even the Torco is junk. Do the math and mix in MS109 or equivalent. A good race gas is clean and will actually raise octane without the negative side effects.

[Camfab]

I agree with NEVER running octane boosters, mixing race gas is the ticket, just make sure it's unleaded!

Bingo...unless you want potential with your fuel system and O2 sensors.

[Simms]

What's wrong with just running any 100+ unleaded race fuel? We have some at a local track but I can't remember the exact rating.

[Steve M]

Cost.

Higher octane fuel burns more slowly. You can lose power if you run too high an octane for your tune. A bit higher for safety is fine but running 100 octane when your car only needs 91-93 is counterproductive. I have real life experience with this at the drag strip. I filled up with 98 or 100 octane (I forget which it was) and my ET's went up. I was confused by this so I did some research and found out why. And of course at $8 or so a gallon, it is freakin expensive.

Another very good point, I noticed the exact same thing.

Good info, and also a good reason to tune lambda instead of AFR.

[EdwardETraylorIII]

Don't waste your time. Use quality 93 and forget about it.

Interesting info. Thanks Jack.

[Jack B]

In most cases a wideband will read higher (leaner) than actual. The lower the stoichiometric a/f number above, the worse the deviation. Another issue is that most race fuel sold is oxygenated, many are in the 2-4% range and some are in the 10% range, which means the overall a/f will lean out by that percentage if you use 100% race fuel.




Interesting info. Thanks Jack.

93 for me hahaha. I guess a splash wouldn't hurt.

What is 93 octane?

Fuel with ethanol and less BTU's............lol !

[Jack B]

I believe it is 14.64. Steve is correct, instead of a/f, it is best to go with lambda, for an NA car that is typically .85 to .87. Usually higher torque with the lower number.
