Well not that I care, but can't 03/04 launch at 7K and 05's are limited to 5K stock? Should I assume that all of these great times were done launching above 5K on the 05's? It just seems really odd to me that 6hp and 13lb/ft can have such a great impact. In that case, after all my modding, I didn't really "feel" my car much faster after any mod thus far. And I'm sure I'd dyno at a lot higher than stock. I'm hoping this will change after my custom dynoflash and I probably got used to the extra power and don't notice it anymore.

There is a plug or something that can be taken out that allows the 2005s to launch at higher than 5K.

I had that happend to me when I was modifying my VR4, I just get use to the extra power and the car would feel like it wasn't as powerful anymore, so I kept adding more power.

Not hating bro. Just stating the fact. Hell I'm 21 and I can't spell for ****. Gotta love spellcheck.

You can believe what you want, my friend who drives the 05 MR was very impressed on how fast my car was with just the XEDE. Now if he had his car tuned then it would be different, but the XEDE also controls boost which I was running higher then what he runs stock. Also his MR seems to die around 5500 RPMs where my 03 (due to the XEDE) pulls like a rabid beast all the way to redline. I'm not saying the 03 is better then the MR or any 05 for that matter I'm just saying that even if the 05's have a 10.5, and more aggressive tune, etc. doesn't mean that the 03 can not be up there with just a few mods (ex. 10.5 hotside). Thats already been noted. All in all they are both the same 4G63.

I think I already mentioned that. The 10.5 hotside plays a BIG part in the 05's power, along with the more aggressive tune that they come with. That is why a lot of people were stuck on the fence about trading in their 03 for an 05 while others said screw paying the big dealer markup for the 05 and they went and bought a 10.5 hotside.

I'm very happy with my 03 and had even thought about trading in for the MR when it first came out I was just not happy with the markup and the improvements didn't really astound me as much as I thought they would have. I am looking forward to the IX MR.

I love the completely unrelated and random posts from users that just pop up in threads. We need to call the Orkin man every now and then.

On-Topic:
When I only had an intake and a BOV, I went at it with another 03 evo on a straight who had an intake and IC piping and walked him by quite a bit. He was surprised by how fast my car was. I think it has a lot to do with the 10.5.

ok about the power lost after 5500rpm. i also get that and yes sucks but what can change that so will pull all the way. like ecu or somthing or is it like... i dont know.

Someone can correct me if Im wrong but Im pretty sure the car dies up top because it is tuned to be ridiculously rich up there. Ive seen graphs where the A/F graph sinks off the chart around 5k to somewhere in the 9's. A good tune can get rid of that and bring back the top end.

No, you don't get power loss after 5500rpm. It's an illusion. That is right where the factory AFR starts to drop and there is a lull in power, but if you continue to hold down the accelerator you will feel a rush of power as you go over 6k, and it will hold all the way to redline. I used to think my MR was slow when I got it, because in my old DSMs, the power would come on extremely hard in an instant, and then die off at around 6k rpm (smaller 16g's), so I drove my MR the same way, expecting a huge rush of power followed by a fall-off then a shift. Well, the MR only appears to lose power due to the factory rich condition above 5200rpm. I guarantee if you go hold it to 7500 in every gear, your car will feel like a new beast. Then, once you tune out that lull, you will have full, linear power all the way to redline.

My dyno in stock form showed this lull, and it is quite amazing:

It's not a matter of believing or not believing...it's a matter of reality given the proper parameters. So, now you mention that your Xede is a tune + increased/controlled boost. Ok, so that's even more power over stock than I knew in the beginning, but still. If he thinks his MR seems to die around 5500rpms, then he doesn't know the car yet...he doesn't know how to drive it, because he needs to go to 7200-7300 in EVERY GEAR to optimize his power. Of course you're gonna run away from him if he shifts anywhere before 7k, because we make our MAX hp right around 7k. Also, if he shifts at or above 7k in each gear, then the next gear will be right in the sweet spot with no turbo lag and instantaneous power. I even go almost all the way to redline (7600) in some gears at the track, just because of how hard it pulls, and I don't even have cams yet. Driven properly, his car is capable of a 13.0@105. Your car with just the Xede would have trouble beating that, so I think this is a case of a new MR owner not yet understanding his car's power band.

guess i need a 10.5 hotside now. i would like to thank everyone who contributed to my credit card's demise.

so how far can you rev the 05 evo8 like 7500 in each gear for best times. and power. but like turbo like full boost at like 3000rpm or maybe less or more. but thats where i feel most power like 2800rpm to 4200rpm just around there and keeps going to 5500rpm but then dies and then from there almost feels like a v4 pull almost and then kind of goes again at like say 6200rpm and then like to 7000rpm and then next gear. but maybe thats the torque that i feel the pull and then the hp after for the speed.

My eyes are bleeding.

I feel no power at 2800, so I have no idea what that's all about. I don't start making any power until after 4000, and then it pulls like a raped ape all the way to redline (7600rpm). Yes, the turbo spools up before 4000, but that's just tht torque getting started like you said (I think). The HP doesn't peak until around 7000 rpm, and that's how high you should go every time that you want to go fast if you're racing.

For instance, at the drag strip, this is a rough estimate of my shift points:

1st - launch hard, full boost hits immediately but dies off quick - snapshift at 6800
2nd - already at 5400rpm, pulls hard until I powershift at 7300
3rd - already at 5600rpm, pulls hard until I powershift at 7300
4th - again at 5600 rpm, pulls hard to redline, which I hit 50 feet before the traps

5spd gearing is different, so you won't run out of gear in 4th, but your shifts points should be similar.

hehe well every car is diff i pull hard at 3000rpm and im stock. and there is one point i say from 5500rpm to 6500rpm lost of power but comes back but not as hard at from 3000rpm.
