Octane boost / race gas

[Wes Howell]

Just a quick comment.

For those not at sea level, hot environments or just pushing the car hard.... get some octane boost or run a little race gas.

The car is so much happier and less inclined to pull timing when the DME is running an extra few pounds of boost due to higher elevation / heat, etc.


I'd suggest giving it a shot. Car is much, much happier especially if you're rallying it hard.

You can also throw some e85 in there!

Do you have a logging tool to see exactly what's going on or are you pretending the car isn't pulling timing?

[Clark_Kent]

I'm not sure how much value this "comment" adds with no support. As stated above, is there a log, dyno chart or other evidence to support your statement?

[Wes Howell]

I have lots of logs and have been working on a little tuning, etc. Pretending? Hah! this forum kills me. That's pretty douchey.

Not hard to get this car to pull timing stock - especially if it's hot, runs more boost due to elevation and you have crappy 91 octane. Don't need charts to prove that.

That's why people run octane boost or race gas with the SC kits.

Just wanted to mention to those that the car will run better at 93 or higher octane and it's worth a shot. Not hard to throw a little race gas in a car ya know. Sorry not posting logs or dynos for something this trivial. If you don't think this car will run better and make more power with higher octane then I don't know what to tell you.

Lol, i think you mean to be on the e92 m3 forum...

Considering he has an F82, I'd suspect you're wrong.

Also, it is common knowledge that the car would run stronger with higher octane. The SoCal 91 is garbage. I can't speak for the timing, considering I have no tools to check logs, but I imagine Wes is completely correct. Just because he didn't provide empirical evidence doesn't make his comment wrong.

Sure... then why mention superchargers and how is he tuning his car exactly?

The comment is obvious but unless you mean to make it very technical somewhat pointless.

BMS has proven, with dozens of Dynos/logs, that octane boosters work. They don't transform your gas into 100 octane race has, but it certainly helps when running higher boost

He is just saying that it has helped the S/C guys...

Sure, his comment is obvious, but let's not be dicks. It seems so common these days that those without a dog in the fight have the most to say.

Thanks. No kidding.

For those with an F82, it's just a heads up / word of advice. I was pleased with the outcome. Have run lots of BMW's at this elevation and higher temps....

Next time I'll make sure to have "empirical evidence" hahahahaha

How do you figure? My last 3 BMW's were M cars. M5, SC'd E92 M3 and the F82 M4. Pretty sure I'm on the right forum.

What do you drive? Oh a 135? Sweet.

I have E85 and 100 right down the street from me

Haha, so how and with what are you tuning again lol?

This little 135 will gladly race you anytime ...

You really are a douche.

I'm on the BMS tuning / JB4 beta program for the M4. Have been for several weeks. Been logging data and running several different tunes. Currently on a custom tune.

I'd imagine once my car is tuned up a bit that racing your 135 would be a lot like our conversation on this thread. Wouldn't be very hard to make you look stupid - you do a great job of that all by yourself.

Where I live (Austin,TX), we don't have 91 octane. We have 87, 89, and 93 octane. It has been that way for years, so only choice has been 93 octane.

Oh wow, look... a dick on M3post that is talking down to a prospective 2nd year owner that is looking for as much objective data as possible... well there is a surprise... not.

Instead of making a pointless thread like this that states an obvious comment... at least do yourself a favor and provide more context. Oh wait, that's asking a bit much I see... K, well I will take my 135 and go over on e90post and create the same thread under N54 engine tuning... we'll see how well stating the obvious goes there.

If it's such an obvious comment then why did you demand "empirical proof"?

You inferred I didn't know what I was talking about...you inferred I had no data (I was pretending) Then you said I was on the wrong forum.

Then you seemed to be convinced there was no tune....(lol?) why was that funny?

You just look like an ass dude and I'm happy to call you out on it.
and you got a little bit of pushback for being a douche - that's all. Maybe you'll thank me later.

Or feel good knowing that you're one of those douches that is so oblivious that no matter how douchey you act towards other people - it's always that other guy.

Have fun on the other forum.

Interested to hear more about this^^^.

(Funny retort btw)

So far.... 91 octane + heat + elevation (which will already cause the car to run more boost) = not ideal results.
Crazy to think that it's possible for the car to hit 25 psi stock.

However, running higher octane is much better. Still not close to being done.... Not ready to go to E85 yet either.

Been running about 6 gallons of race gas per tank and the car is STOKED.

Pulled convincingly on a SC'd E92 (VF 550 kit) the other night. Friend of mine that I used to race when we were both SC'd E92's. I pulled harder on him than I ever have...and my last car was a VT-625. I'm sure elevation is a key differentiator as my gut tells me that this wouldn't be the case at sea level. We've done around 5 solid pulls in varied conditions. At 91 octane we were much closer but his car has never pulled on the F82. Pretty amazing. Personally, I feel this car does really well at elevation.

The F82 is much better at making power in varied conditions and so far the cooling system seems top notch. After a few pulls, I let it idle and it sucked the temps down to 190! My SC'd E92 used to run at 235 and once it hit 235 it stayed there....It pulled timing a lot in the heat.

Anyway....new exhaust arrives tomorrow. Downpipes soon after that. Should be some nice media coming soon.

Anyone see any benefit to running higher than 91 with everything stock? Where I am all I can get is 91, but I know some areas have higher octane gas commonly available. I wonder what octane gas the car is tuned for stock..
