PS: Back half mph has a lot to do with gear spacing, shift points, and where your power is. My car is a little tepid in the 1/8th, but picks up almost 27mph on the back half due to having to shift out of third just before the 660' trip lights.

 

Let me know how your car is doing couple of thousand miles from now!

 

+1 You need to get at least a few thousand on there before youre making max hp.

Outside of that.... stop trying to over-analyze the situation. This is what you need....

practice, practice, practice, and when youre done with that .... more practice.

 

if you would have gotten a 1.6 60', your time would have been 13.1 as drag racing is all about the launch. it can be done on the stock clutch but this will prematurely wear it out quickly.

use your stock 5500 rpm launch rev limiter & slip the clutch quickly like a bike-do it too fast car will bog, too slow clutch will smell REAL bad. if u do it right, you will NOT have any clutch smell.

shift quickly into 2nd after the launch & carry the rest of your gears out to about 7200rpm.

the stock Advan tire is more of a road race tire so run about 20-25psi of tire pressure.

remove the restrictor pill out of the clutch line.

hope these tips help...

 

The limited is @ 5000, not 5500.

Dont take your restrictor out & just dont listen to DJ.

Also, just for ***** and giggles, do a compression test. I think you might have started beating on the car too early, not completely sealing the rings, leading to lower or uneven compession (FYI, IXs have different rings then VIIIs). This is just a guess though, not saying its the answer.

 

The limiter is 5000 for the 03-05 VIII. It was raised to 5500rpm for the IX. I'm sure his power is fine. He just needs practice.

 

Not on my and others IXs, but that was a rumor at first. Maybe it has to do with the different ECU revisions.

 

 

To everyone else THANKS!! LOTS of GREAT INFO here to Digest!!!!

And Yes, I'm planning Soon on getting it tuned, at which point it'll be a mute point!

THANKS!!!! :-)

 

I can't say for sure because I had mine set to 6k with my tune. But virtually every review of the IX out there states it as 5500.

 

Actually he's right on this one. Nobody knows if it was due to warranty issues, but mitsubishi did in fact revise the 9's ECU mapping more than once.

Yeah bro, sorry to break it to you but everyone in here is right but you. Listen to Warr he is actually giving you some informative info. You're driving just plain sucks, and to be honest, is downright pathetic. That doesn't mean it can't be improved upon. I'm sure 90% of the people on this forum didn't drive that great the first time at the track with their Evo's also. Like others have said it is a difficult car to launch. So stop taking it so hard or making excuses as to why your times were slow, just accept it for what it is. And what it is, is that you drove you car poorly, therefore it performed poorly. No more, no less.

 

The limiter is 5000, not 5500.

There are always revisions, but they don't randomly make the cars much slower with those revisions. There are tons of different firmware udpates for 03-05s within the SAME year. Having potentially 3 for the IX so far is nothing special. Mitsu certainly didn't update the firmware to the point of making the IXs slower than 03s...

DJ, no way would he hit a 13.1@99 even with a 1.6 60'. You can't just subtract the 60' difference and multiply by 2...that isn't how it really works.

 

Yeah I think your correct.

 

You are right - the trap speed is not a driving skills issue. Your car is not making the power it should.
