I have you to see a thread (i've searched) with any results from a bolted 110 octane tune cobalt dyno or track. Im getting tuned soon and wanted a 110 octane tune for the track.

I dont want E85 because its not as available as the 110 octane.

Anybody have nay info on this, most threads like this end up on a rant and never really answers the question. Which is it worth running good increases?

 

I am curious about leaded fuels with our style engine. Subd.

 

No problem with 110. I ran it, made 501whp. I also ran it on the stock turbo as well .

 

Cmiller, Thats what i was looking for, Any number or anything while you were stock?

 

if the car was on a 93 tune and 110 was put in it, wouldnt it run better?

 

Not necessarily.

 

it would be just like putting octane boost in your 93oct gas right?

 

Unfortunatly no.

Would prolly run worse actually. With racegas you can lean it out a bit and such.

 

Leaded fuels will take out the O2 sensors eventually.

 

Yea but you can still pop it oh and take a torch to it a bit and the lead will come off

 

No. The higher octane fuels burn more slowly at the same compression. If you don't have the right tune for added timing and such, you're just spitting out unburnt fuel into your cat.

 

Damn, I guess be a test dummy with 110 Octane since i cant really find a defined Answer or numbers.

Speed Unlimited is like 7 miles away from my house, and the track i go to also sells it.

So if i get tuned for it i'll see if i can get some 93 number and some 110 numbers.

Planning on tuning on 3/10

 

^^^ this

you really need a tune for the 110 octane/race fuels.........



I'll be assuming that the 110octane tune.....will result in the same whp numbers of an E85 tune.


when I browsed on the evo forums....there's still a debate between E85 vs 110 octane
those who converted from 110 octane to E85 claim that they have a lil bit higher whp....plus of course the price is way cheaper.


The race gas vs E85 have their pros and cons.

if race gas is more convenient for you...and you're only gonna use it at the track, go for it.

But expect your whp numbers to be very similar to the E85 tune numbers.

 

On a stock turbo lnf, you will gain very little power by switching to 110 octane, whereas E85 is worth significant gains. If you are running a larger turbo that allows you to run a lot more boost, then you can start seeing some gains from 110 over gas, but E85 will still make more power.

 

Thanks Guys, Yea E85 is no where near where as Race gas is very accessible. Like i said right up the street. It would only be for track days.

Matt as in small gains. how much is small?

 

since you guys probably already done the E85 vs Race gas at your shop.

You guys get more power from E85, huh?

What race gas you guys used?

I wonder instead of 110....how about those 116-120 octane, have you guys used them as well?

there's one E85 station in boston...which is about an hour drive (w/o traffic, about 1.5-2 hrs w/ traffic)......away from me.

But there's tons of Race Gas vendors locally where I live.

I was just wondering what numbers you guys get between those different kind of gases.

Thanks!

 

Only problem with say c16 is the cost. Its getting to be 10.00-15.00 a gallon

 

Yup, I think it's about $14/gal here.

 

On the stock turbo, I gained nothing switching to 110 octane. On the 252 turbo, I think it was around 10whp. If you were running 30psi boost or more, the gains would increase quickly because you would have to run the 93 tune very conservative, but not the 110 tune. E85 on the other hand will result in gains at any boost level or on any turbo.

 

ok gotcha! good to know!

I'll probably be running 35-40psi....so this will be helpful!

yeah...same here!

god dammit....i wish there'll be an E85 station nearby soon!

it's a win-win situation.......cheap and effective

 

E85 may be less than 93 per gal (usually) but TRUST me, you'll be filling up a LOT more...

 

Damn absolutely no gains what so ever? Thats disappointing.

My Buddies 2010 GTI made about 20 HP with 110 Octane. with the K03 how do we not have any gains?

 

Someone explain how this is possible, Im not a Turbo Di guru by any means but? well just look

 

I C, 110 octane = unlimited speed also for veedubs.
Tune for 110 octane sounds like the answer. But not going to be fun on the wallet.
e85 is cheaper but more fill-ups

 

Yea well people are saying no gains. I just need it for track days im not getting it all the time.

And yet again i dont have e85 anywhere near me.

Im just trying to understand. meth increases the Octane and its gains, but running 110 Octane doesnt?
