Is Racing on 93 "Safe"? Not really.

[Speedy!]

Well there ya go. DGatzby's looked exactly the same but I guess it's still not enough proof for some

When you first posted that I was pretty shocked though to be honest Mike.

Did you catch my prior post on octane points verse numbers? And how misleading some manufacturers can be with advertising points of octane versus numbers that octane is customarily measured by and what they’re really getting numbers wise for the amount of product their adding? Allot of people don’t catch that and they think they’re getting much more octane # boost from Some products than they actually really are. Add the correct amount to get to the octane you want, 98-100 from 93 and you’ll see your spark plugs and everything else change colors that’s for sure no matter the product name or claim!!

 

[Speedy!]

Yep, that's been a pretty common "trick" with those little bottles of octane booster you see for sale at the part stores.

 

[Mean Cat]

You better look closer then.

How deep are the tulips in the exhaust valves Mike? I KNOW you measured them? At least 1/4 inch or are my eyes playing tricks

OK, I see that clearer now on the center of valve.

I think that's the difference with Octanium, they go by points.
Boostane goes by beginning octane # to desired octane #.

What is scary is mine did NOT have a steady diet of the stuff either. Darn it @Speedy! this race gas added instead is going to be expensive!
But, if it runs more smooth and don’t break, I’m in and I again thank you drag racers for sharing what you know.

Look at the pictures of the Octanium can a few posts back, it gives the NUMBERS of octane increase by amount used. 7 numbers (70 points) per Qt in 10 gallons of fuel. So 1 can will make a true 100 octane fuel from 10 gallons of 93, and it works, I’ve proven that years back and posted that on the old forum with log screen shots, little did I know what it was doing to my exhaust valves.

Yeah Mike, on Octanium it takes 32 oz to get 7 #'s for 100 octane. When starting with 93.

Boostane is 9.2 oz to get 7 #'s for 100 octane.

I use 2.5 oz in 8 gal. to get to 98 octane.

I know, any amount of it can leave residue but just saying that's a big difference in amount used each time.

Has any of yalls engine failures been caused by the MMT residue that you know of ?

Nope, engine loved it, but I don’t know what another 10,000 miles of it would have done and I don’t know if the increased CR because of the deposits had anything or not to do with the damage the engine did incur when a different tuner redid the gasoline portion of the tune and melted a few plugs in the process. And this was no fly by night tuner, was/is a highly regarded tuner by a highly respected member of this forum and poster in this thread. That question is Like trying to count the Licks that it takes to get to the center of a tootsie roll tootsie pop. Awls I know is I won’t use it anymore I will use a different form of fuel that runs cleaner and safer because you can test it real time what’s going in the tank such as Ethanol.

I can respect that & yalls options & the mmt residue is a real thing, just haven't seen failures caused by it, anywhere.

 

[Speedy!]

It's likely what caused DGatzby's issues after seeing his heads and maybe Mike's too but that ones more questionable IMO.

 

[jonx96]

I’ve been reading up on preignition. Kind of brought me back to thinking of this. 🤔

 

[Speedy!]

Pre Ign is usually caused by hot spots if I remember right.

I am going to challenge this line of thinking - that Boostane Professional is depositing less MMT residuals than comparative ocatne boosters (VP Octanium, Torco, etc.) because you are using less Oz to reach the goal octane number
There is no magic, secret formula to how these work - they are all utilizing varying levels of MMT concentrations and aromatic solvent mixtures.
Boostane Professional vs Boostane Premium - Porfessional has a much higher concentration of MMT per Oz - the rest is martketing. Same for all the other brands.
If you are concerned about how much MMT deposit you are going to incurr you need to dig deeper and look at MMT concentration per Oz.
It does not matter how many Oz of product A vs product B you are using - they have differen't concentrations of MMT levels per Oz. To raise the level of ocatne by "x" amount of points it takes a certain amount of total MMT, some products are just more concentrated thus requiring less Oz to put the same amount of MMT into the motor

In a nutshell what we've learned

 

[jonx96]

Correct and some of the hot spots I was reading about were caused by carbon build up

 

[Speedy!]

Honestly, I'd be a bit more worried about it building up enough to have piston to valve contact and or a piece(s) chipping off and going through the motor.

That's why I love @16GoManGoHC2's E85 porn pictures so much. Those cylinders are so clean I wouldn't believe it if I hadn't seen them for myself (in the pictures).

 

[Speedy!]

I'm super impressed with E85. There's a tipping point for it though IMO. Using it does require a pretty hefty fuel system upgrade on the Hellcat with dual pumps AND big expensive injectors. RE/TH get off a bit cheaper as they already have dual pumps, so for them just big expensive injectors LOL.

Once you're at the fuel system upgrade point anyway, E85 starts to make a lot of sense.

I see your point.

I guess my fight with all of this is I like the convenance & no hassle of 93, not to brag that I'm on 93, the extra expense of initial upgrades of pumps etc. for e85 & the hassle of testing it, or expensive race gas.

I know, I know, you have to pay to play, but I'm playing already.
