Update*12.49@109.7mph Stage 2 sti, 100 oct map...

[Swine]

Just got back from the season opener at MMP. Ran a 12.49@109.7mph in my 05 sti with my 100oct map. Previous best was a 12.57@108.9mph.

Mods
-3" catless turbo back
-topspeed protune 93 and 100oct maps

Weight reduction
-removed spare and jack
-removed rear seat and passenger seats(only like 40lbs, i was hoping they would weigh more )
-Alittle less then half a tank of gas.(so much for weight saving )

Thats all, thats it... no track tricks. Let the car cool 30mins before running.

Slip
60--1.69
1/8--7.97
1/8mph--87.2mph
1/4--12.49
1/4mph--109.7mph

damn SHHWWWINE!!! that awesome man! congrats

[Swine]

Hahaha, thanks brotha...i just kinda keep chipping away.:)

[VDUBNDizzy]

If we both keep racing, do we both keep getting faster? I see a trend here. :O :D

[easy2speed]

7.97 in the 1/8 shit! Good job man. I still want a ride when you have the interior back in.:D

[Nstig8r]

Great times.... We should go from a dig sometime now that I have a clutch.

I wish I could run race gas without fear of my rods ventilating the block. I would love to see what it would run with 104 gas and the new clutch if I ran 111 traps before. Have you tried 104 gas yet???

[ActiveAero]

That's awesome dude.

Ive tried all sorts of gas, ranging between 110-c16...but i just mix it appropriately to make 100.

Ver nice :)

[funinthecav3]

Is there not a straight 100 octane around here?

[Swine]

Not that i am aware of, but i wouldnt use it anyways even if it was available.

[phillyd]

hellava job swine:D

[funinthecav3]

Swine im gona have to ask why you wouldnt want use a 100 octane fuel? Not to be a smartass. I just want to know your reasoning.

He would be mixing a mid octane gas with the already pre-exiting 93 octane gas in his tank...that is what I would assume which would result in less octane

I use this simple formula...a+b/2=RELATIVE OCTANE RATING

100+93=193
193/2=96.5
110+93=203
203/2=101.5

I would prefer to go with an octane level higher than the octane my car was tuned for rather than the lower level octane...for the obvious reasons

If I am wrong...I will allow swine to punch me in the head later;)

You forgot to take into account the higher specific gravity and burn speed.

Well that is obvious. I understand mixing fuels to obtain a wanted octane level. I want to know why he wouldn't want to use a fuel thats already 100octane fuel? Since he has a map thats tuned for 100 octane. If you think you will make more power with a 106 octane fuel(which the car is not tuned for) than you would a 100 octane fuel(which the car is tuned for) you would be wrong.

The problem is that its much more a pain in the ass to either a)drain my fuel tank or b)run my car until its out of gas and carry a 5gal container of flamable liquid with me to fill it back up when it runs out. It is much easier just mix the appropriate race fuel with my 93 oct tank to get desired octane. Plus, all the 100oct i have heard of is not leaded, and in this case i want lead(which all of the 110+ i have access to does have lead).

Besides, i always mix on the safe side, becuase a 4k motor is alot more expensive then an extra half gallon of the sweet stuff for just a bit more det detturent.

Now if all i ran in the car was 100oct pump, and i had access to an 100oct on pump or had several 55gal drums full of it at my house...then yes, i would just run 100oct in it.

[funinthecav3]

Definately understandable. Well I know enough about the benifits of octane and the downfalls of not enough octane. What i don't know about is the benifits of leaded fuel. Why would you like to have it?

You do realise how much of a pain in the ass it would be to drain a tank, for a negligible gain?

Even more knock deterrent. I think leaded fuel may also burn cooler?

The higher the octane, the less explosive a fuel is. What i dont know is if they calculated the octane with consideration to the lead as well, or if its just an additive....

Oh ya it would be a huge pain in the ass. I know i wouldnt go through that hassle. But if you have a good idea when your tank is getting really close to empty you can just add 100 octane at that point. If you have lets say 1/2 gallon of 93 and 5 gallons of 100 octance, the reduction in octane would be very minimal.

Gotcha. I just got done reading an article of a conversation with someone from Sonoco. Heres a paragraph from the article
"Blending a leaded fuel with unleaded, however, pushes the octane up a bit more than the math would suggest, due to the effect of the lead. Just a gram or two of lead blended into the unleaded fuel will raise the octane number significantly. Commercial leaded racing fuels contain anywhere from a trace to six grams of lead per gallon. If you were to mix 50 percent 110 octane leaded fuel with 100 octane unleaded, you would actually end up with an octane number around 106 to 107. Keep in mind that even the smallest amount of lead or leaded gasoline with unleaded, could spell the end of your catalytic converter or oxygen sensor. The same holds true for using octane boosters intended for off-road use only. A word to the wise, check for any lead content in all the additives you might mix with your unleaded gasoline. And check with your state emissions regulations for street use."

That lead will collect on your O2 sensors and cause interesting things to happen.

No way!:mono:

I enjoy stating the obvious

You do realize how easy it is to put a hose on the return line and let the fuel pump drain the car? ;)

About as easy as it is to take the feed line off and let it pump.... More work then I would want, but I know how you like to go around your ass to get to ya elbow.

Hell, my car has a bolt threaded into the gas tank under the car that you can unscrew and drain your tank in seconds. Pretty cool

Same here and thank goodness since I had to drain my one time.

You probably should not have mentioned that drain plug with some of the guys on here.:D

I think I will be ok:)

Congrats on the time man. This is Allen, the guy with the Silver Z that you raced tonight.

I just wanted to point you guys to an interesting discussion that was had on my home board recently about homemade octane boosters.

I plan to use toluene later early next year when I shoot the dry shot to the car, as a little added insurance. ( Along with the bigger injectors, tune, etc... )

[Swine]

Yeah i plan to get ahold of some toulene one of these days.:)
