Maybe thats true, I remember hearing Tony from ME engineering stating something about driving the crap out of the car to put the ECU into "performance" mode.

 

ok i went to the mechanic and everything is ok with my car. My y pipe is not the problem and my car felt good today. We drove his G35 and even though his is modded more there wasnt that much of a diff. There was a little lag at 3 or 4th geat i think but nothen to serious, he said it might be comen with the g35 5AT. ohwell back to my boltons coming soon pulleys, hi flo cats, full fujitsboro exhaust

 

Rather than say 'why can't i do this/ why can' ti do that?', go read people's reviews on it - 99% of the time, people bitch about serious downlow losses w/ it and minimal uptop gains. The stock y is more than fine


T-U-N-E

 

^ please elaborate one what u mean by T-U-N-E. we hooked the computer up to it and saw everything was fine. what bolt should i tighten or loosen so that my T-U-N-E is finished?

 

lol...he means get a Tune...dyno tune or utec or some computer garbage you dont need....it aint that big of a deal...if people are saying the y pipe hurts em then take it off...i dont know...imho i jsut cant see ity hurting you...maybe hurt you down low and you car gain up high...or vie versa...im not sure...

 

answer u pm box. yea my pipe isnt doen much for my car and def isnt hurting it im getting hi flo cats and a exhaust anyway

 

dyno-tune. your a/f is probably skewed as is; adding more free-flowing stuff will just make it leaner and won't make optimal power at this pooint.

 

there is no problem here....3rd is where the power difference between the 2 cars really is...3,4,6 if im not mistaken.

 

Laughed My A*^ Off

On a more serious note, I got an AT. Let me know what happens as you get ur exhaust on...

 

should've saved that 50 bucks and spent it on a 6MT, you would've never asked this question. Since you asked, gearing is everything, old WRX are rated the same on the quarter as the 6MT G, if you raced a new one, you wouldn't even be close.

 

Huh? Stock, the old wrx wouldn't touch a 6mt g. I don't know about the new ones. Haven't raced one.

 

Simple answer: No

My 5AT sedan with a Z-pipe consistently saw 98mph traps. I expect it to be in the 14.1-14.2@99mph range with the spacer. That's more than enough ET and MPH to keep nearly all the stock and close to stock Rev Ups at bay.

You guys really need to take your cars to the track and see the real truth. Racing on the street proves VERY little. You need timers to really see what's going on.

 

Stop wasting your money on mods that don't work. The only NA mods worth a damn on the 5AT are:

1) MD spacer or Crawford plenum 10whp
2) Headers 5-7whp
3) True dual catback 5-6whp
4) TS ECU flash or piggy back ECU 8-10whp

Everything else is a waste of time and money. Some of the mods may actually hurt performance too.

You wanna be quicker? Shift the 2-3 and 3-4 at an indicated 6800rpms. Dump the 19s for a set of light 17s or 18s. That eye candy kills performance. Yank any excess weight from the car like thumping stereos, golf clubs, dead hookers, etc.

Finally, the 6MT does have the advantage from a roll. There's no way of getting around that. It puts more power to the ground and it has better gearing. From a stop is the 5ATs game. Putting a hole shot on most 6MT drivers is cake and the first 100' of a true drag race (1/4 mile) is the most crucial.

 

True, that's with a retarded 5000rpm clutch dump launch which is a risky action with the glass 5MT in the 02-05 WRX. Also, the 02-05 WRXs did run 14.1-14.4 in the mags, but look at the trap speeds. They're in the 93-95mph range. A G35 6MT should see 98-99mph easily. MPH is the indication HP. ET is the indication of traction.

As for the new 2.5T WRXs, they are pretty stout, but they're not that much quicker than the old 2.0T models. I have a friend that totaled his 12.5 second 04 STi and he purchased an 06 WRX. In stock form is did a 14.1@95mph with a 1.85 60 foot. That's hardly impressive to neither him nor I. He added an STi turbo, turboback, injectors, and a piggyback ECU. With $2500 in mods, the car now runs a more respectable 12.9s@104mph.

 

Ok, I read every post in the thread, but there's one phrase that I'm not familiar with that I don't understand...

Can someone be kind enough to explain to me "running lean up top" and "running lean"? What's that mean?
