Question Speed limiter

Anyone know how to get rid of the speed limiter on the lancer. Is stand alone the only way. Heard some piggy-back systems do this. Don't know where the limiter hits(probably 130MPH from what i've heard.) That and simple tooning is all i want but don't want to invest an arm and a leg if i don't have to! Any ideas???

i dont think it can go much faster without the limiter, cuz once i get to like 125 it doesnt seem like it will go much faster

Unless you're going so hard-core-*****-out (read "beyond 'simple tuning' ") that you're going to go faster than 130, I'd recommend leaving the speed limiter on unless you're making it a non-street-legal car. I think removing a limiter is a crime here in Jersey.

i think youd have to change your gear ratios to go faster than that

Got all the goodies with the best yet to come...Turbo, B&M, and Brakes. Think she'll push the 130 mark no problem! I know i've got big ones but i'm not pushing over 110 unless necessary to win. HA!

Check out the ride so far... Best of all(and to hell with those who disagree) i've kept the outside stock! Of course the springs took her down an inch but you'd have to know the car to tell. I'm going better on rubber to though same size as stock except 205 or 215 if will fit!

just cuz you have that stuff does not mean your top speed will be any higher, im pretty sure its all in the gears

Think of why you feel a lack when you get going that fast. The engine just doesn't have the power to overcome the damaging effects of aerodynamics, powertrain loss, traction, etc! Thus if you boost the HP+TQ you should get her up there! Noted you'll never go faster than the gear ratio's will allow but doing 125 at 4800-5000RPM seems like there is room for improvement. What ya think?

If you'd like i can direct you to a theoretical program that can back that. Just take any car in its list and run the simulated Quart. The top speed of the car will be listed on the right... note not top in Quarter but actual top given gearing, aero, etc. Now change the HP and Torque....See what happens! Of course download the free version unless you like the program after using it!

16.6QTR @84.4 Top theoretical 122... then at 225HP,235TQ and drivetrain changes(as i have) getting rid of wheelspin you get 13.8QTR @102.2 with a 151 theoretical top. It also shows graphs comparing mechanical/aero/clutch/accessory losses. Where they meet is how it gets the top speed. Pretty close seeing that at around 118-120 is where the big drop in MPH gain happens in my stock lancer. Unless i'm going down hill(cheat!)

ROCK can tell you that there is already a proven 14.4@99 using turbo/TB, Test Pipe, RRM Muffler, utilizing 7PSI on(don't quote this)93OCT. Guy said he spun tire forever! Need the LSD! YEUP!

My bad it was a 14.6

I hope this is not too simplistic...

Every 1000 rpm is good for about 23 miles per hour in 5th gear (this is an eyeball measurement based upon the tachometer and speedometer). With a redline of 6000 rpm, your top speed is going to be 138 mph.

Obviously the stock 120 horsepower is not going to be sufficient to push the car that quickly. Assuming the motor is putting out enough power to overcome aerodynamic drag at that speed and beyond, if you want to go faster you will need to:

A) Increase the actual gear ratio in the final drive
B) Increase the effective gear ratio with larger diameter tires
C) Increase the redline of the motor
D) Some combination of the above

The big question you need to ask is do you really want to be going 130+ in an economy car that is designed (by some very talented, intelligent engineers who more than likely know their business very well) to travel at speeds that will never exceed 110?

Yeah i would have to agree with Dannoh on this one because of the redline factor. I would love to remove my limiter but would find it pretty useless to do so Ive been above 130 and it is pretty dangerous/scarey and not the smartest thing to do....I dont plan on doing it again but then again who knows.

maybe the tracking on this is out... i asked if anyone knew how to, inexpensively, get around the speed limiter. I'm just looking for info on this as i don't know of a way other than going stand alone. As for all the other talk school is out and i don't care! WAHHHHH!! Seriously though, if anyone knows if it can be done let me know. Thanks!
