topped out ??

[jakethesnake]

iw as driving my 240sx on the freeway yesterday and i wanted to top it out and it wouldnt go any faster then 110... i jsut swaped my SR in..what are they suppose to top out at and what do you think the problem is??
im at stock boost, almost everythign stock, FMIC, and a few goodies..

[slider2828]

What exactly do you mean by wouldn't go any faster than 110? The revs wouldn't go any further, describe the experience more...

[sillyvia13]

factory speed limiter..
you can splice a switch in to remove speed limiter..but you will not see speed do to cutting limiter it is same signal from ecu and cluster.

you really do not need to go 170! but when you do ! you tube it

[Pink Slut]

you need 2 of these, by tonight





afermarket chip/ecu would resolve it

Yeah factory speed limiter is right.

Buy a Power FC or get a Haltech.

No more speed limiter than come get it tuned.

Fuck rom-tunes if your close to a dyno.

They are all just flat timing maps anyways, don't believe the hype

[garagelu]

Yea I have upgraded turbo with power fc and I got my car up to 150 mph the other day. Did it once and no need to ever do it again. Just wanted to see what it could do. I think I was at around 6800-7000 rpm. So still had a little more room to go.

[steve shadows]

exactly

Not this shit again.
it goes from VSS to cluster to ecu.
so cutting at the right place will not leave you w.o speed.

Also, I doubt that 170mph is possible with SR without ALOT of mods. Wind resistance is a bitch.



BTW this is me, on stock ecu and bald ass tires and tired suspension.

[jakethesnake]

do i really need to get the power FC or can i just chip my ECU??

[Mr. Jesse]

just get the fc

unless you know how to solder and remove solder like a pro

[jskateborders]

some dude was on here selling a speed limiter cut controller. But 110 on the freeway is hardly a good Idea

[DRFTSAINT]

If you don't have the funds for a FC or other tunable stand alone, buy a Greddy Speed Cut Controller they are like $80 tops on ebay

[HalveBlue]

OR...

you could just disconnect the wire that goes into the ECU.

Did it, speedo still works fine.

[ILoveMyRHS13]

Ah the advantages of an automatic... Well only one, no limiter! The rest SUCKS.

[blownmotor]

I did 140mph on my s13 and it was hella scary( did it just to see if the car could do it) And most likely you're watching too much Wangan Midnight. 240sx is not a top speed car. Oh and real racers don't use NOS

170 is pretty fast... what is the max speed the 240 can go with the stock gearing? (5spd)

no matter how much HP you have or aerodynamics...you will run out of gears if it is stock gearing

Constant timing per a given load does not correlate to a constant amount of ign timing at a given MAP on a MAF based setup - big difference there. That said, many of them are flat, but it honestly works best on most cars that have anywhere near "stock breathing."

Power FC sucks balls though, can't believe you're recommending that over a ROM tune. If you can play Gameboy forever to tune your car, just man up and learn to rom tune your own car.


BTW - my car on the factory speed limiter would shoot out a 3-4 ft flame out the exhaust on the track. Probably not healthy for the turbine to do for very long.

[WoolyS14DET]

disconnect the 5th gear switch on the tranny and see what happens ????

Really, Ive drivin alot of cars, and my s13 seems to be the smoothest when the speeds get up there. Everything else gets a little scary

[jspaeth]

It shouldn't be that hard to calculate/figure out top speed.

Cd*frontal area of many cars can be found online.
Multiply this by 1/2*speed^2 to get drag force.

Multiply drag force by velocity to get power (power is force multiplied by velocity, or power per time).

So essentially, hp required to overcome drag goes as v^3.

Look up some high performance cars, look up their Cd*area, and look up their wheel hp, and you can get an idea of top speed.

I believe, in theory it is higher than you think....240s have a lower Cd*area than Ferraris, so at high speeds, with identical hp, 240s can pull harder.

The caviat is that the reason Ferraris have more drag is bc you need drag to produce downforce.

Result: A 240 and Ferrari with the same hp, 240 could pull harder at high speeds, but is much more likely to flip over due to lack of downforce

6800 at 110 or whatever? What you think an extra 400 rpm will give you a bazillion miles more... Dun think so... Probably governor at 125. Extra 400 rpm is asking to blow at redline at that speed.... but heck whatever. cut the wires...

[IRN]

hit a bump and get a few inches of air at 110 with a 2 way lsd and your not going to like the landing. it gets pretty scary at high speeds.

What car are you talking about? I hit 110 mph at 4.7k RPM in 5th gear on my S13. That means I have almost 3k RPM more left before the rev limiter, which is about 65 mph more.

[Erjay1]

Damn 110? I can do 110 in 4th gear, maybe even 3rd...lol. Fastest Ive gone in my Z is 163mph.

[rowdogg03]

How the hell can you guys say your going 140-150 when the speedo tops out @ 110? Good guessers?

Just cut the VSS wire... and enjoy...

[Ineedparts]

I want a diargram and color of this wire, because i need to cut it also.

Data logit + Power FC + Dyno Always > Rom Tune (No Game Boy Involved fuck the hand commander) I'd throw it in the trash if I had one.

Haltech is the best. Hands down for the money. I have used AEM and I can personally say the software useability is stupid and over done, trys to make you feel like your doing something over complicated and insane. it's just maps. It's like stupid colored maps and aweful schemes to every drop down etc. Haltech and AEM are the only ones I reccomend period but no one on this forum is about to shell out for one or has the balls to run one.

I can't believe your suggesting thata Rom Tune done with some sort of generic saftey map from accross the country is better than a Power FC (which is just like a rom tune) don on a dyno specifically tuned for that car with the tuner in person monitoring the outcomes.

YOUR DOING IT WRONG
