Are all EVO IX's diffrent do to the MIVEC?
 

i bought my evo IX in august and since then i have done some things to including; BR turbo back,o2 housing, turbo manifold, intake, 255 walbro, 780 injectors, forge BOV, RR MBC and a flash and tune from road race (RR):) . know heres the question, when i was stock my freind had just bought his evo IX as well and for some reason he would beat me by two cars when racing to the end of 4th. Now i know what your thinking im just a ****ty driver. but we tested to see if thats what it was and it was not becuase of shifting. he would pull me half a car in 3rd at about 5000rpm's well after we had shifted and in 4th he would pull 1 1/2 cars deep in fourth:crap: . i was speech less. i swear he was on nitrous or something. but he is my good freind and i know he is not. we talked to Al at tunning tech and he told my freind it is becuase the mivec head and no 2 evo IX's are alike in that aspect. he said that there are fast ones and slow ones so pick wisely.
Has any one esle heard of this or had this problem. sure i beat him know but it took me a good amount of cash to do it.:D

You'd figure that the same car would be the same motor.... How would you decifer the fast from the slow ones? The engine code is stamped the same. "4G63"

^^ Lol

Do a smell test. The one that smells like perfume will be faster. I hear the perfume mod gives you 15awhp more than one without.

Maybe your friends car is a factory freak! No two cars come out of the factory the same. Did you ever try driving his car, and have him drive yours when you guys were doing your runs? There maybe also a difference in how you broke in your motor compared to how he broke his motor in.

No two cars are equal. It's normal to have factory fluctuations. Yours may have been pushing less boost than normal while his was normal, or maybe his was higher than normal while yours was normal. I've seen IXs run 16-17psi from the factory and others run 20psi, and the difference is noteworthy on the dyno. However, when both get the same mods, they usually go back to normal.

PS. Bad move on the injectors, but the rest of the mods are pretty good as long as that MBC is quality. I have never seen nor heard of an RRE MBC on an Evo, so I hope it's as good as a Forge or Hallman. Btw, a flash IS a tune...you said a "flash" AND "tune." Just a heads up...

or maybe you have a leaK...

All cars are pretty much the same. With equel drivers it should be no more than a half or car distance.

Tuning Tech = good shop {thumbup}

Oh, maybe I can beat u too besides your friend did to u and mine's only a VIII :cool::D

yeah i know the 780 was too big for the time but i bought them looking to the future.
sorry its not rre it was rr which stands for road race. they are the same people that tunned my car.

i thought his car was a freak but my freind nick is basiclly the same way. he would only beat me by one car but god damnit it was still a car.

and yes we did switch cars and still the same turnout.

RRE = Road Race Engineering. I've never heard of just Road Race.

780s will bw too small later if you get a big turbo and have no use now, so you didn't need to plan ahead. You could have waited until you did the turbo upgrade and gotten the proper injectors then.

RRE uses the Dejon power house MBC I believe.

Question: Can you tell me if you obeyed the breaking procedures? Did he?

What's the proper break in?

Proper break-in is in about 500 threads in the Newbie forum.

Mitsu says to not go above 5k rpm for the first 600 miles. It is also important to boost hard and boost often UP TO 5k rpm - just don't rev higher than that. If you baby it, then the piston rings may not seal properly.

Yah dats wha I heard I babied it for 800 miles then it was pedal to the floor when I found out best breakn is hard
