Hey guys I searched this and it seems like the search function is pulling up a ton of "invalid threads". Anyway....going to be doing the 75 hit at the track this weekend. However, we can only get 91 pump gas around here. I'm pretty sure my dynotune dry kit manual suggests 93 octane. Is there an additive that I can get a hold of at NAPA, CarQuest, AutoZone, or O'Reileys?
Thaaaaaanks a bunch guys.

 

TORCO

The local performace shop recommended torco...however the races are friday and i dont think ill get it by then. is there anything else that i can get at those stores listed to get me by?

 

what about a mixture of 91 octane and 110 (should be sold at the track)

 

In Canada (well vancouver anyways) we can get this 10% ethanol 90 octain at some stations for the same price as 87. I've run this with a 100 wet shot and it's been fine.

 

how about acetone?

 

If you can't find TORCO, just cut in a couple gallons of 106. They should sell an assortment at the track

 

I usually try to run with about a half tank (according to my gauge) at the track...so do you think a gallon or so of 106 or 110 should be okay?

 

you will be fine. I wouldn't worry about it with a 75 shot.

 

oh...another newb question. what kind of air/fuel ratio should i be shooting for?

 

the NOS brand bigger can from autozone ect should work well too. should be around $10 for one decent sized can.

 

Look up Alliance gasoline stations. Many of them carry 100 oct. race gas.

 

try toluene, you can find it in paint stores. the octane is 114 and is safe to run as an additive in fuel.
