^Echoed. Good launch, low trap.

 

The big problem at the track in Fontana is the head wind you get. There was a yellow evo there running and he ran the same times he ran at carlsbad earlier that same day, which is about 12.5 at 110-111's. Carlsbad was a bit slow saturday too.

 

I was there at California Speedway (white EVO w/ large tail-wing) and my best run (13.3 / 103mph) is also at night time around 8:00PM against a Power Enterprise big turbo upgraded STi (he ran 12.7 w 106 if I remember correctly). The first 2 runs were terrible for me (13.6/96 and 13.9/99). On that day, we were running against the wing and hot temp. I ran 13 even in Fontana in last May
I tried to beak into the 12s with bold-on mods (turbo-back, boost control, K&N drop-in, ACT clutch, Dynoflash) and 91 gas but no succeed so far. I found that I'm running a little rich and will use the S-AFC II to lean it out before the next event (hopefully Jul 17).
I just want to see how good the EVO is running in a "regular" condition.

 

3000Ways, How many Evos were in the 12s at Fontana. I did not witness any when I was watching. Audi2ptzero, It was a crazy day as I could not pull off a low 1.7 60 ft at either track. Without a full tank of gas 12.3-12.4 at 111mph was possible at Fontucky. Got there at 7pm to watch and they asked me if I wanted a tech card. Okay let see what she will do with an extra 100+ pounds weighing her down.BSed for a bit and from about 9:00pm did the classic IE Evo hot lap display that Smog knows I have a habit of doing at Carlsbad and busted a 12.6 at 110mph and two 12.5s at 109-110 mph.. It was cool at 9pm and not much of a headwind but a lil one. I went 11-0 on the day including the Rodney King type beating I put on you at Ghettosbad.(last statment is a joke as our run was close and you did trap 114mph to my 111mph. So all in all an okay day at two slow tracks with 11 slips ranging from 12.3-12.8. I must say I do like how smooth Fontucky feels compared too Ghettosbad. Ghettosbad is like dragging on a Motox track in comparison. Put Fontucky's 1/4 mile track in Carlsbad and 12.1 or a lil better might be a possibility.OUT!

 

i usually shift in between 7 and 7.5 and i really dont think its my shifting, i had no misshifts and they were shifted really quick, the engine never dropped below 5 or if it did it was 4.5... i was on her pretty good. do you think having a 3 in downpipe 2.5 inch stock cat and 3 inch exhaust would make that big a difference, cause i didnt have my cat delete pipe in yet...maybe there was some restriction, or maybe there wasn't enough fuel to be running 20 lbs of boost without the fuel pump installed....what you think ?

 

There is your Problem right there....


Having Problems with HEAT? Runn 116 Octane, if you are on a stock turbo you can't get it too hot too detonate....

Again a Bolton Evo with a Trap @ 103MPH is slow, that is 100% Stock. Traps should be 106-110. Check your tuning...

 

Running high octane fuel like that will do NOTHING for a car that is tuned on pump gas. Moving to maybe a mixed fuel to about 95 octane will help but anything over 100 is going to hurt performance. Only go that high if the car pings or is running lean.

 

Oh I know but he is having problems to begin with. Don't forget the Mitsu likes to advance timing till it sees Knock, then pulls it back. No Knock @ 116 octane so you would get the maximum allowable WHP when all the other cars are running slower on pump.....

 

I find that odd. Then why would a tuner do different tuning for 91, 93, 100, 104, 110 and C16(117 octane). If they just had to do one and the ecu does the rest. Because most ecu's pull timing out and some will only adv so much within its spec programming. I have heard of people trying to run C16 on cars only tuned for 100 octane and end up making much LESS power in the end.

 

Well the map will only advance as far as allowed, but as soon as you up the boost or even one spike you get less timing. So if you allow higher octane it'll cut out variables.


When I ran 116 I also ran 25PSI....


But yeah if you just run a stock car with that much octane you would actually lose WHP because you will be VERY rich. I though we we talking modded on a stock turbo and Stock ECU, sorry.....

 

Mail in flash ? if so are these the same mods that you told Al you had ? Are you goin from a 3" dp to a stock cat ?

 

But not all peole mod the car and tune it for 100+ octane. This means a car modded and tuned for just 93 octane wont find much more running 116 even when running 25psi. The problem is the ecu will not make up for all that octane when off boost which will kill tq at the start. The car can also run very rich before all that boost hits which again will kill tq. Take some tq away and it takes longer to get to your hp.

 

Well if things are hot and Aitr intake temps are over 100Degrees and the track is what 120, I think a Higher octane will help to combat these conditions.......

 

yes those are the mods i told al, and i was running the stock cat at the time, not the cat delete, and no fuel pump... those will be installed before i run it again, i was not having any problems with heat at all, and i was running about 3 gallons of 110 octane fuel mixed with about 6 or so of 93 octane... i dont think i was running rich, my air/fuel gauge isn't reading right so i dont know yet, i have to get that repaired and see where i am running then. i appreciate all the input on this matter though guys, any ideas or thoughts are greatly appreciated

 

Air temps are not really the problem. I find that I run good in hot temp if the humidity is not too high. I have done my best runs in 100-110 deg temps in dry conditions. If your looking to battle high cylinder temps all you have to do is drop down to a colder plug. This is the reason I log all my runs using a lap top and a wide band 02 sensor.
