1.The reason why Evolutions do so well with a flash or tune is because to pass U.S. emissions or whatever it is the car has to run rich right?

2.From a Stock IX to a car with a TBE, MBC, and a good tune or flash you can achieve AWHP numbers from 310-330?


Reason why is because some dur dur's on another site *cough* Fbody *cough* are saying that I am wrong and have no clue what im talking about. And I just want to make sure im clear with what im saying. Also links of dynos and/or articles would be good. I honestly wouldnt know what to search for in the search button. But the main reason why I posted this thread is because im sticking up for the Evo's instead of the Fbodys...wow, I am turning

 

Mostly run rich for safety.

 

But they do run rich right?

 

1) we run rich for safety. as for emissions i dont know an exact answer but when we lean out our engines we are using less gas...thats a plus for emissions. lol

2) a evo IX can hit 300hp on a really aggressive tune alone...however, no tuner will do this because it's really aggressive and somewhat dangerous. so yes, a evo ix with tbe and mbc can be thrown into 300+hp range. note that most tuners dont tune that agressively...one tuner i know that tuned his really aggressively said that he wouldnt tune a customers car like that because he doesnt want to be held responsible incase something happens to the car and he would have to charge more for that tune (due to it creating more power)

 

evos run pig rich...i think the IXs run more rich than the VIIIs

 

Thanks for the replys guys, keep em commin!


And when your talking about "for safety" safety from what?

 

Yes, they do run rich. When you get a tune, the map is leaned out which makes some of the power and timing is added which makes power. The stock ecu map is pretty conservative so there is a good amount of power to be made with a tune.

 

safety from blowing our engines. when we are rich it allows the engines to last longer since the engine isnt running at 100% full potential.
when our maps are leaned out the car uses up less fuel (better mpg) and makes for power...however, that will cause our engines to (exhaust gas temp) to be hotter. if its leaned out too much then bye bye engine. lol.

 

Safety from detonation....as the fuel/air mixture becomes less rich the cylinder/ exhaust temperatures go up. Engine failure on a turbocharged car is usually due going lean, detonation and breakage of rings and piston lands.

 

Yes this is correct, and some have even made more.

Hey did you ever read my thread on LS1tech.com in which my supervisor was a disbeliever also, at the time he had a stock LS1 Camaro SS. We challenged each other to three races, but we could only both have a limit of $1,000 worth of mods. Welll we both went over $1,000 (LOL) but not by a lot, but I needed a fuel pump to complete my tune, but I couldn't do it, because it would put me too much over the $1,000 limit. So I basically raced him w/ half a tune and almost still won and I should have won. I won the slow roll race, but he got me by a car on the high speed roll. But he beat me from a dig and he was on street tires, man that so sucked and proved how horrible of a drag racer I am, I should have beat him two out of three. But the point is, he gained a lot of respect for the IX.

 

No I never saw that thread on LS1tech, there is so much stuff going on at that site. Its hard to keep up with everything. All LS1 owners think their cars are gods. Yes, I too though so at one point with my big head but im way over that. And yes top end the LS1 will win, aerodynamics plays a big part in the top end.

 

so which vendor has the most aggressive tune? dynoflash?

 

1) The tune to run rich isn't to pass emissions standards, thats what cat's are for. The tune is set that way to be safe on the crappy gas we are alloted. You and me especially since we are in california in the land of 91 craptane..

2) The mivec engine seems to do a lot better with less which is good news for you. I wouldn't be at all surprised if you reached those numbers or better. Vishnu's 400hp package for the IX is basically a flash,TBE, and a boost pill module. If they can get 400bhp out of the motor with just that then 330whp shouldn't be an issue.
