Nice!

 

10 Pages and No slip??? This thread is null and void to ANY statement

 

Edit: 11

 

changing the air filter to another one is completely different, if you believe otherwise you are reaching.

why is 100 octane gas sooo much different than 94 octane to you? you can buy it at the station if you choose.

the 3" exhaust analogy is terrible.

 

Jeff, if I could buy 100oct at the pump, I would do it every time I filled up. There is no 100oct within 100 miles of me and that goes for most people. It is race unleaded race gas. They sell it at Summit Point Raceway for this purpose...for racing. It is not illegal, and it is not leaded, but it is not pump gas. The person who started this thread said himself that he believes he got gains from tossing in the 100oct, so it was obviously done IN ORDER TO GET gains. Just as I don't know for sure that the 100oct gave him 10-20whp, you don't know for sure that it didn't. This must be done again on regular pump gas in order to be legit.

What you haven't seen me do is request the timeslip, because I'm not actually arguing that a IX can't do this. I know that my 13.17 at 103.89 was a 13.0 or 12.9 with just an AVERAGE launch, but I didn't know how to ovecome the 5k limiter. Just going from a 1.92 60' to a 1.75 60' was all I needed to hit 12s that day, but I didn't know what was going on with that limiter until I got home and did some research. So, a IX with the same power can also hit 12.9. A IX with more power can do better than a 12.9 on a mid 1.7 60', but for it to be legit, it needs to be on 100oct. I know how it all works, but the cars on the West Coast definitely make less power on 91 even with no tuning or boost control, despite the factory richness.

 

This is such a joke. ...thank you for helping me with my decision about never making another post here on this site. You are all haters

 

i don't ever remember seeing a dyno of a car bone stock, then a dyno with ONLY gas added. they all up the booost, or lean the afr, or add timing...or a combination of the 3. there may be a gain, and if there was a gain, it would be so marginal its rediculous.

you insenuated that you just dumping in race fuel added 40hp and that you wouldn't mention it next time you went out. well, how fair is that? you switch maps on the afc and add 2-3psi of boost....

if the car has enough knock from the factory, that a 100/93 mix adds 2mph to the 1/4 time then some engineers at mitsu need to be fired.

 

No need to get angry dude ... People just need proof for what you are claiming ... you can't expect to come in here claim some #s and have no proof to back it up ... back to the topic at hand ... I think the issue we have is what different people consider is stock. I think you guys need to look at the SCCA Solo2 handbook as what they define as stock. You'll be surprised what mods are allowed under stock class ...

In SCCA solo2 a stock car is allowed to change out the air filter and even install a catback exhaust. Any type of gas is allowed. I think this is a bigger sanctioning body with a set of standards than peoples personal opinions as to what is stock. Therefore the car is stock!

All cars run stronger in colder weather its a fact. The air is colder and more dense (more O2 per volume also has a slight leaning effect). The temp of the air coming into the engine is cooler, thus more resistance to detonation. 100 Octane fuel helps against det, yes it burns slower but it also doesn't pre-ignite under higher temp and pressures. The ECU is thus allowed to run fully advanced timing. Yes it is true that the stock ECU is tuned for 93 oct but that doesn't mean the 93-94 oct you pump at the gas station is actually 93 Oct it might be lower, it might be higher ... that is why Cali 91 Oct is $hittier than 91 Oct you buy in the rest of the country ... so yes 100 Oct will make a difference in power levels ... period end of that discussion!

This car was run stock with race gas ... we just need a time slip to confirm the guys claim.

 

Ok, no on 3 things here:

1) I didn't say anything about a car dyno'ing stock, then dyno'ing with just race gas or a mix of race/pump. I said cars on the West coast with 91oct dyno significantly less than those of us with 93oct...and that's in stock form.

2) I didn't insinuate that I gain 40whp just from race fuel. I said more than once that I get the FULL GAIN from raising boost and leaning out the S-AFC (I don't have 2 maps, it's an old one with one setting). I also said I realize this guy wasn't able to change boost or tune, but that doesn't mean there was NO gain from the 100oct...just not 40whp.

3) I'm not saying it has anything to do with knock reduction. What I've found is that if I used leaded race gas while on my pump gas tune, I go majorly rich. I then have to lean out significantly just to overcome the richness first...then lean out even further to get a race gas tune at 12.0 AFR or higher. When I was on the stock cat and could only use UNLEADED race gas (100/104), this did not happen. I did not go rich and immediately ran better on the same pump gas tune that didn't knock. I gained even MORE mph after raising boost and leaning a bit more, but that doesn't change the fact that I got gains initially with no change. I don't know the chemistry behind leaded and unleaded gas of higher octanes, but we can't just assume the 100oct made no difference. The driver himself said it made gains. He was at 100 for a while then went to 107. Why did he suddenly gain 3mph? Did he put the 100oct in before all the runs or in between? Were any runs done on straight 93? What was the mph at the 1/8th and 1/4? We don't know.

 

I completely Agree, And you have alot of patience

 

Well, the way he told the story was the race gas was in all night. Of course if he left out the fact that he went from the 104 to the 107 after adding race gas...then something is up.

And the reason cars in california put out lower numbers is because 99% of the numbers we see are tuned numbers, and of course, you can't up the wick as much on that gas...no, the numbers are going to be smaller.

If you are suggesting that stock EVOs dyno significantly less(>5whp) in cali vs nevada...well, i have never seen any data to confirm that...

-Jeff-

 

I don't know about Nevada, but in places where they have 91oct, the stock numbers are lower across the board. I mentioned that I was referring to STOCK numbers, not tuned numbers. Even in stock form, Evos dyno less with 91oct.

 

hmm, i haven't seen it. not many people dyno their car stock, so i guess its going to be hard for me to find enough sheets to make that more than a theory...

But, 2 tenths and 2mph is a lot, regardless...and again, if adding a couple gallons of 100 octane makes you gain that...something isn't right.

 

My PERSONAL opinion( no proof to back this $hit up) on stock 92 octane(hawaii) my car runs on a different "map" than w/ 94 +. I have blended gas to 94 octane and even 96 octane. even tried about 97 octane .no real difference after 94+. however there is a difference in plain 92 octane and 94 octane. i'm guessing that people in california who have 91 octane is @ the biggest disadvantage. I can actually "feel" the engine switch maps when i go back to 92 from 94 octane. even my gf was asking why my car sounded "funny" when i filled up w/ 92 after the last track night. i explained to her that it's because the map is switching. The manual reccomends 94 octane.(could have been 93?) read the owners manual if you don't believe me, and it also says performance will be diminished if you use less than that.


I believe using a higher octane @ the track is not a "mod" but actually a safer thing to do .




I also believe if you are going to brag about something, you better have the timeslip. I.E. if i claim i have cured cancer, i better have proof before i publish.


as for asta4125, considering you only have 24 posts(incuding a whole bunch in this thread alone), you should respect some of the people here.


Also, if you don't have the timeslips, the least you could do is post all the info like a timeslip w/ the reaction time, the 1/8 mile info, and even track temp. this would help us evaluate it more and even lend some credibility to a claim.

 

right.
It's not hard to post numbers if you are legit.
