I would not go back to the stock ecu and karmen vortex sensor after driving an evo with aem and map sensor.

 

My previous EVO VIII, an '03 GSR was modded by Busted Solutions..... If you do a search or two you'll find plenty of history to support my experience..... Yeah, AEM EMS with AEM UEGO controller, HKS cams, camgears, big injectors, Walbro pump, TB exhaust with TP, big Greddy FMIC, fuel rail, Exedy twin plate clutch, etc....... The car ended up a total piece of ****....... I got so sick of it that I finally traded it. I'm extremely happy with my new '05 MR which really drives perfectly. Yeah it drives like stock which is as good as they can run driveability wise. The only issue I have is that the cat back I installed (saved from the car before) is a bit louder than I like. Otherwise it really drives perfectly and puts down 257 whp on a DD dyno. As I said before, I'm not hating or putting down your car of your efforts. I just flat out do not believe the BS about the driveability. I know better, some other guys might not know and others don't give a crap and accept whatever driveability they get after their mods. I've heard that song and dance before and I've actrually seen and driven modified EVOs. To the last one, if they were extensively modified and got stand alone EMS, they did not drive as well as stock. Maybe you have the one miracle car, but I'll only believe when I see it. In the meantime, I'd advise any newbie to expect serious driveability issues if they modify the car past a certain point.....

 

his torque is right on. all the stock turbo evos making 400tq take a crap right after they make it. they are also hitting around 27psi tapering to 21 on race or alky. hmm, i wonder where he would be if he was hitting 27 psi and tapering to 21 on race gas. and if he was at 400tq at 6k he would be making 460hp, 530hp at 7k, and if he could hold it to 8k he would be making 610hp. lets be realistic, this is PUMP GAS!!!! don't make stupid comments on this thread unless you know what your talking about and run something besides the STOCK TURBO!!!!

 

Silverevo8, you are right that a car cannot drive any better than stock...hands down. But I'm saying that my car runs as close to stock as possible right now. So much better than when I was running my emanage tuned by AMS(but thats cause the emanage is a POS). But when I was stock I put on an intake and bov a few days after I got my car and driveability was so ****ty. With the AEM EMS you can tune to accomodate a loopey idle due to a bov or you can even tune to accomodate 280 camshafts if desired. BTW, silverevo8 who was your aem tuned by?

 

Well it's not BS and my car drives better now on big turbo and aem ems then it did before on all the same mods except for injectors, big turbo and aem ems. I have not stalled once since the aem but it used to stall all the time becuase of the cams and bov so I like it much better now and do not regret it for one minute.

 

Thank you for the comments. I am getting sick of trying to defend my tuner and my car it's getting old. I will see soon what it will do on 27psi and some race gas.

 

Ditto .

 

Hey, now I can agree with you. I accept your comments about the driveability improved from the previous mods..... What I'm talking about is the driveability of any such modified car versus a stock car. There is simply no comparison.

I've been there, done that. My excursion into the big power mods did not start with the '03 GSR either I'm a veteran of adding forced induction to Miatas and Acura GSR... The EVO mods were by far thye most extensive I've tried and my experience was not good. As you say, you had all kinds of problems before and got some relief with the AEM EMS. I can believe that, but I still say that nothing has better driveability than a properly running stock car. No stand alone EMS will match it specially with more radical mods. If you and other guys are happy with your AEM EMS, more power to you (pardon the pun ). From my experience and point of view, I'll stay with what I have now thank you.

 

Just so we can settle this torque thing once and for all. I am going to put some links to threads so people can see what whp and torque other big turbos are making.

That's it for now, you will see a sizeable difference between horsepower and torque. But you will also notice the torque curves will keep going up instead of peaking and falling right off. I hope this will put the whole "omg your torque curve" thing to rest.

 

I will disagree though when you say "there is simply no comparison." Because my idle is better than a bone stock evo and my afr's are where they are supposed to be instead of pig rich.

 

If you turn off your A/C you might get numbers like mine. 515whp and 414.5ft lbs on 21-22psi. With less lag too.

Just a thought...

Dude those are some awesome numbers.

 

Nice photochop, you got me good on that one. I didn't look close enough at first.

 

On most of the larger turbos there is usually more of a difference with torque and horsepower. On smaller turbos like the stock one the hp and torque numbers are usually closer together.

 

Guys I think several of you are getting way off the point in why this thread was created. I cannot believe how some people just can't stop, I know that most of you don't mean to come across the way you do but go back and read this entire thread it sounds horrible. This was started becuase issues were lined out due to very minor things that several of us have encountered while installing a turbo kit. Now that they are lined out the HP numbers are up and very satisifying. Damn congradulate the guy, especially somone that put together his own kit and supported his locals.

But its very nice that several of you can comment on torque simply becuase maybe you think you have more, I don't know thats just a guess but the reasons have been explained above why this occurs with bigger turbos (especially on a stock block car with no intake/head porting) and only on pump gas. Race gas will be different but there is nothing wrong with being safe, it is just smart from my point of view and from his tuners I am sure. I know that some of you have gotten the shaft and or had bad experiences and I have read several of your threads, I know it sucks becuase customer service just isn't what it should be especially when spending as much money as several of us have but lets not micro manage Strongbear becuase he has everything taken care of.

Please no flame meant just wanted to make sure everyone realizes where this has ended up when the real outcome was great.
