rev that thing up tonight at mid-night should be one heck of show try and coordinate with the fireworks.

 

Yea after so many RPM you begin to loose power. Remember our cars are capable of 120bhp@5500rpms so reving any higher causes a lose of power.

 

There is no power that high in the rpm band due to the intake mani, exh mani, and cam profile.

 

From what I understand is that our motors can handle another 800 rpms without any probs. I think R/R set up there ECU reflash 500 over stock. Even thought the 4g94 is a balanced motor from the factory, 9000 rpms is going to kill someone. especially if they are close to the car. Did you see how skinny the rods are? But from I understand that up to about 700 rpm above stock the Lancer still pulls

 

im sure it'd still pull after that, but remember, after 5500 rpms were still loosing power based on every single stock dyno we have.

so safter so many RPM's it'd be better to shift up than to keep it in that gear...

i only know 2 cars runnin 9k rpm redlines....the s2000 and the rx-8

 

hey drive, even though we lose power after 5500rpm, we would still be pushing higher hp than if we shifted up. and if we had another 500rpm's or so, when we upshift, we would be at a higher rpm than normal. so we would shift into more hp than normal. so although we may lose some hp, essentially the extra rpm's would be beneficial. correct me if i am wrong, but shifting a little higher doesn't sound bad to me.

oh and i believe their are different rev limiter settings for each gear. no, i don't go around redlining all the time, but i did learn to drive stick on this car. so i have made mistakes, and from personal experience i think they have slighty different settings for each gear.

 

I think baha really hits it all right there. The intake manifold is to long to make effective high RPM power. It's designed for all around torque in the midrange. You'll never see runners that long on an Honda motor revving to the stratosphere. The stock exhaust manifold just needs to be pulled out since that first cat is quite is obviously the biggest issue (albeit that has me thinking of how effective a shorty manifold ala Focus' motors would be on this car). As far as the cam, I think that's one of the bigger if not biggest thing. Keeping those intake valves open paramount. Then things like timing (be it cam and/or ignition) need to get changed and then you need to make sure the car gets the fuel when/where it needs it. Then obviously there's the non-tuning portion where you simply have to upgrade the head hardware (lifters/springs/retainers) and build the low end to spin faster (rods, lightweight pistons, balancing) to make sure nothing flies apart on you. Import Racer magazine had gorgeous pics of a totally built ZETEC motor that could produce incredible horsepower in NA trim. Completely revised intake manifold with twin throttle bodies, completely built head and block and an only mildly tweaked exhaust (still retained the close couple cat). I believe the engine is capable of running high 12's from what I remember and this was with spending about 5k. A very good article for those people who can afford to extremes.

 

'afford to the extremes' they only spent $5k bro...

if u get the RRM Headers, a Test Pipe, Cat-back, and the intercooled turbo, u've spent $5k+ and are only in the 14's...lol

albeit im sure with the 4g94 you'd have to go ALL custom and it'd cost more than $5k to do it...but in the end performance wise were dropping $8k if we go RRM's way and were hitting high 13's like Boe used to....or just low 14's maybe

 

The RRM reflash raised the rev limiter to 6900, and I have not had any trouble after finding it a few times on autocross courses. But then again, I don't spend much time up there.
