No, what I'm "seriously trying" to get you to understand is that 100 octane is NOT race gas (as some have termed it), and was being used in this circumstances (26PSI) to have a better margin against detonation, not to increase power. Anyone who has ever compared their fuel and timing maps between pump and race gas knows that C16 or similar fuels have totally different maps than 100 unleaded or any other gas you get out of the pump... 100 UL may, in some areas, allow for more boost, but it wasn't done here, limited to 26PSI, when the ambient temps are in excess of 100F.

The point is that that, as tested, there is no major difference in performance numbers between 93 and 100 octane at the boost level of 26PSI.

 

Boost is not everything, if it was, everyone with a MBC would be a tuner.

Saying there is no performance advantage between using 93 and 100 octane is ignorant.

The "as tested" disclaimer obviously protects your statement a little bit. I still think it's really stupid to run 100 octane and run the same timing, AFR and boost as 93, but if you like spending more for the same performance, go ahead.

 

I can count just like most of the EvoM readers. What is "pump gas" in some parts of the country is obviously different than others. We continue to swerve off topic, though, because you continue to try to make an issue out of the use of 100UL fuel while you ignore the fact that the boost in the test you complain about was limited to 26PSI, thus limiting any significant advantage in power that might in other circumstances be a legitimate topic of discussion.

You are welcome to your own opinion as to what is "stupid". Personally, I think that using the extra safety margin obtained by upping the octane of your fuel and preventing detonation in a non-knock-equipped car by spending an extra $1.xx per gallon for your fuel is pretty smart.

 

Not ignoring it at all, you are ignoring that boost isn't everything.

93 limited to 26psi

vs

100 limited to 26psi

I would place my bets on #2 every single time that it will make more power.

I'm done with this simply laughable discussion we are having, as at this point, we aren't even talking about the red anymore.

 

Well... I guess I need to know a little more into what goes into making the turbo and I should of said 40R to some 42R's .....

 

So how many of these are you going to be able to produce within the next few months?

 

Count me in on the group hug, but nobody better grab my a$$!

I think we will build a couple hundred over the next few months, lord willing and the creek dont rise, as they say here in Texas.

 

razor i have to agree on this one!! more octane means more timing, we all should know what that means

 

I'm certain that I'm wrong, but 93 octane has a faster flame front than 100 octane. Because of that, 93 doesn't NEED the timing that 100 octane uses. Remember, the maximum force on the piston should STILL occur at the same point in piston travel. Now, introduce more HEAT (such as Texas and Oklahoma are currently experiencing) into the intake vs say 75-80 degrees on the West Coast, or even 90 degrees, and typically, in OK, TX, we need to PULL timing to compensate for the heat. IF the 100 octane allows for more timing in MOST parts of the country, that is tremendously negated by the heat we experience in OUR part of the country. Now, where am I wrong. Sorry for the OT Robert, but not everyone understands 105-110 degree temps like you and I experience in our part of the world. I would imagine that what we run on 100 here in the summer heat is pretty close to what others in cooler parts of the country run on 93. Even 1-2 degrees more would not result in much power difference, maybe 5-10 whp.

 

I have the XS POWER exhaust mani, as far as the pump i havnt ordered it yet.. i'm still trying to decide if i really need the double or not , and if i should get the 1000's or the 1200's injectors=(

 

Robert: Can the Red be fitted with a 9.8 HS?

 

No reason why you couldn't other than you may spool it up fast enough to have a surge problem perhaps?

 

wouldn't a 9.8 defeat the purpose of the turbo....that's like buying a 35R and putting a tiny exhaust on it.

 

Robert i was wondering how much boost you are getting on wastegate pressure?? do you think that 23 is too much for the fp hp actuator?

 

Finally got to have a RED in my hands.. Very sweet turbo.. Customer snagged and i forgot to take pictures of it before he left.. We have 3 more on hand though if anyone is interested.. They wont stay long i am sure..
