Carlitos,

...actually he was running .2 slower with the stock ECU + race gas. (12.2 vs 12.0 I believe). Therefore the difference of running C-16 with the stock ECU and the AEM was .6 sec. (11.6 vs 12.2) That's a lot.

 

You are being foolish. Read carefully and you will see why. Don't make me sick Warralton on you.

Ah hell, let me spell it out for you:
His AEM was specifically tuned, thus optimized, for race fuel.
His stock ecu was tuned for pump gas, not race fuel. If it was properly tuned for race fuel it would have made around 30 whp more than pump gas. As it was, he ran a 12.0 on pump. With a proper race fuel tune, he definitely could have done at least an 11.8 @ 115.5 (maybe a tenth better).

So, his AEM could be attributed to making a solid 2 mph and .2 sec difference. That is what the rest of us dolts have been seeing and doing on these boards for two years now. BTW, I think .2 sec and 2mph is a great improvement!

 

Honestly - it pains me to see you have any problems wih your car

I still remember the 1st time we met at ATCO

Phillyevo is a classy guy and a guy who loves evos

BTW - I have your tune saved - when you have a chance - send me the stock ecu I would like to add the new anti lag two step feature to your ecu. With a better '60 foot you would have been in the 11's on your pump gas map which is a great accomplishment. I think the two step will improve your 60' times - although at thsi time of year traction is hard to find.

 

I was aware of all that: stock ECU was tuned for 93 and AEM for race gas.
I just wanted to show the instantaneous improvements he got by switching from one to another.
I also think that the AEM would've make a .2 sec improvement over a stock ECU tuned for race fuel.

 

Funny bro !

 

Scary enough. Yes.

 

I see the pictures now in the first post.
Honestly I think it can be only one of two things. You either over-rev'd and floated a valve and it made contact with the piston. (most likely bending it)
Was the rocker on the valve properly. The pics are hard to tell but looks like it lay have been hitting the spring retainer.

Can you push that lifter in?

Oh and if you decide to get rid of the AEM let me know, I am in the market.

 

Please post in english only.

Sergio, yes I know he went .2 sec slower but if we take the first run on pump gas we can see this guy already ran a 12.0 so the difference between the 11.64 to the 12 flat is a mere .3sec.

Anyway, what I trying to say here is that we are not sure why his car ran slower with the race gas and stock ECU. For the most part most of the EVO running higher OCT gas ussually run a few tenths quicker and a bit faster on the trap speed.

We can't determine for sure why he ran slower on the race gas stock ECU run, it could have been that he did not lauch well.

Most of the people on this forum would expect that if you are already doing 12 flat on stock ECU and pump gas that you would run a few tenth of a sec quicker and a couple of mph higher trap speed if someone does not believe ask Warrtalon or myself WE DO RUN FASTER ON STOCK ECU AND RACE GAS.

I am inclined to ssay that he had other issues with his car or that his car was not launch agressively or shifted properly.

Sergio, even you were telling me that you were planning on running quicker by adding some race gas on your 93 oct tunning.. the .6 sec of difference that you are refreing to, yes , it is there but does not make absolutely any sense what so ever.

Ask Warrtalon or myself wich have run at the track more than 100 passes and we will tell you that race gas most of the times improve your horsepower, top speed,1/4 mile times and trap speed.

Vishnutunning made an extra 8whp on a dynomustang on a 03 Evo by switching from 91 to 93 no tunning at all, just baseline. I have many reasons to believe there was something wrong with it.

Would you think your car could run .2sec faster on 89 or 87oct? That is my point, I can't really speculate on why Phillyevo ran slower but in normal conditions he should have run faster which brings me to the same topic. If he would have run in normal operating conditions he should have been in the 11's on stock ECU and race gas wich again it would demonstrate that the AMS $1700 toy would have give him a mere .1sec improvement


Last but not least, would that guy(Phillyevo) had his car tune for 100OCT on a dynoflash he would had run a 11.6 already.

Its sounds like a slight rod knock......

 

Sean, I think we have that covered thanks.
But If I need a hand I will let you know.

I remember that too If it was not for you my car would not be a bad a$$ toy today you tought me alot THANKS Al......

 

Michael just wanted to leave... he thought his motor was trashed, too. It was making no power on that map at all... AND it made some weird noises. But the compression test was perfect... and then we saw map 6 selected, lol! Needless to say, it ran like a raped ape after we put it back to #5.

Not to be cocky... but both of us hear that a lot. It saddens me to not see Subies do better than they do. Both our cars aren't exotic. Easily replicated set-ups. Oh well... thanks though!! Remember, the 2nd run, you beat me Dammit!!! lol!

Seeya Saturday...

I would almost be willing to bet that the noise started to be heard after the 4th gear misshiftThat sux,hope it is just something small in the top end,but like David B. said
not likely,sounds like all the info given=spun bearing,but lets hope not,just hope it is something Minor in top end.Good Luck

 

Just to be on the safe side I am going to get the whole motor done and putting the car back to all silver...........................

 

well, I guess it will be a nice christmas present, good luck with it!

anyone here run the 284 cams? whats the gain over the 272s?
