is it really worth it to get tunned with race fuel for nitrous or just stick with 91? will it really make a difference?

 

come on. nobody knows? and yes i tried searching

 

Here in Al 91 is mid grade and 93 it high. Why not just use 93? I guess if you have a UTEC and have an extra map, why not. Here it is hard to come by race gas unless you are at the track. I'm not sure what kind of power difference it would make.

 

That all depends on your definition of "worth it." If you like being on the safe side, then, yes, it will be worth it. If you don't mind too much (won't spray too much, too long, too often, etc), then this may not be for you. Also, depending on your shot size, it may or may not behoove you to get a tune, regardless of if it's for race gas or not. And for the record, there's no power difference from just the gas alone. However, with more retardation in your timing (and with help of race gas too, if you so wish), you can and will make a bit more power.

BTW, what are your 1/4 mile times and trap speeds like N/A? On the juice?

 

13.5 na and 12.4 on 100 shot untuned

 

150 shot...I would throw down for some race gas whenever possible. cheap insurance for your motor...

100 shot, I'd just tune it....you dont wanna spray for a year on stock timing...take the timing out before the stock ecu sees knock and takes out 6 degrees.

 

thanks i think ill do 2 maps- na and 150 shot on race fuel

 

I ran 109 unleaded sunoco race fuel with the 150 shot... A/F was about 12.2!

I ran 93 for the 100 shot.

Isn't 12.4 a little lean for 91?

 

i believe he ran a 12.4.....also with race gas you will be able to advance the timing to make more power not retard that would be safer but net you less hp

 

12.4ET on 100 shot is pretty damn good.

DR's?
