topped out ??

[blu808]

I use a gps system for dead on accurate speed readings.

The fastest we got my fd upto was 174 mph at the san jose grand prix. 6950 rpm in 5th gear. and it still had another gear (overdrive). Anyways. I want to build a silver state classic, or bonneville car if I ever have money.


Btw, all our cars create lift at speed. even if we have diffusers and gt wings.

What we really need is full undertrays.

Among many many other things.
Wont work.
Not even with a piggyback

very nice +1 for you my friend

Thats what im building right now, our cars have a few down falls but i want to at least hit the 200mph marker and get my red hat

The sensor in the tranny is the problem, the gear just goes haywire after about that speed.

[sillyvia13]

really!
fuck...that was the only real reason for me to install...I wanted to see a top speed numba!

[steve shadows]

Get a Haltech or Motec and a wheel speed sensor

[advin builtsr20]

I did 140+ multiple times in my s13 and the only time it was bad was with the cut springs I had on it. Knew it was 140mph cause I asked my buddy to stay next to me in my 2g GSX (speedo goes to 170mph). After a nice full coilover set up it wasn't too bad at all. I used the cusco coilovers. But one thing I will highly recommend if you plan on doing high speeds is a good brake set up!! something I wish I had done before I planned on going fast...after i sells my s14 my next s13 definitely gonna go foot work first then swap...

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.

A ROM tune isn't necessarily done across the country. I was more talking about someone spending $100 on some hardware and doing it themselves on a dyno vs. spending a retarded amount of money for all that Power FC crap to do essentially the same thing. Or getting someone local who can tune their ECU.

I guarantee you I can match any result you get out of a Power FC with a ROM tune for a fraction of the cost. The only time a Power FC makes sense is on an S14 setup that is hard to find daughterboards for.

MAP based setups are nice, but there is something to be said for the robustness of a MAF setup.

Got pics of where you were doing 174mph?

[240cracker]

if you do end up getting a power fc i have one a brand new in the box for s14 sr.
idk what u have

power fc is the shit

There is a little saying in business time is money.

How much time does it take the average car enthusiast to build his own ecu, or add a board to an ecu and learn how to properly tune it or buy all the supplies, hardware nessicary.

Proove all it will cost is 100 bucks. Then Ill believe you.

Robustness of a MAF setup? lol

Yeah I love stabbing in the dark when I am tuning a timing map.

I want to know PRESSURE if I am tuning a forced induction car that see's a race track.

( I would data log pressure over MAF readings at least )


PS. Power FC is not the shit, Haltech is the shit.

[xplicit240]

LOL. yeah man i shared the same experience. my needle was way passed the odometer. anyways i know you got the problem figured out but all you needed to do was buy a simple speedlimiter cut.

$40 burner and $60 for daughterboard and chips - I've even done it for cheaper before.

Yes, robustness of a MAF setup. I've seen blown motors because something caused the VE of the engine to change, and the AFR leaned out. Very easy to do with a MAP system. Issues with a MAF usually cause a lean mixture. I can't count the number of standalones I've seen that for whatever reason did not compensate well for ambient temperature/pressure differences and had funky drifting AFRs, or didn't adjust timing due to temperature well etc.

I know very accurately where on the map a car will be at a given power level, it's just something you learn after a while and can do some basic math. Don't feel bad though, I've been doing the whole tuning thing longer than you have. hahaha

main straight away at the san jose GP 2 years ago. Conrad grunewald was driving it at that point.

He said He hit 7200 rpm (limiter), but the radar gun from Champ car officials showed 174mph. which would be closer to 6950 rpm. Still fuckin fast for that small of a track.

[s13drob]

i think most cars can handle top speeds. all depends on suspension and downforce

yeah I have a sr power 240...s13...and at high speed sshe gets real light...
teh car tells me to slow down...at about 140 150...no aero at time...was front end more than rear...rear always feels light tho....

[jskateborders]

weird.. are these coupes that everyone is topping out?^^^
I went like 130 in my teg and it felt like it was gonna lose it.
145 in the s13 felt nice, solid, fully controlled.

[blu808]

110 in a 240sx feels like you are about to crash.


140 in my GTO feels like I can take my hands off of the wheel, set the cruise control, and text message people.


It is all about setup.

Hahaha.

Def, Steve's point is that having something custom for your setup will always beat the "guess and check" ROM tuning that = 99% of the ROM tuning biz. I know you know your shit, and apparently have had great success with ROM tunes, but for the majority of people, a standalone tuned on a dyno will be reasonable as far as time and money, and perform close to ideal.

I used a GPS on my bikes when I used to care about top speeds, and hit a GPS-verified 202mph on my 2004 GSXR1000. Scary shit, but showing people the GPS's memory for 'top speed' and watching their jaws drop is fun.

I've tuned standalones too, nothing against them, as they have cool stuff. They're just way more expensive than a daughterboard, which is really the only "hardware" you'd need to purchase if someone was tuning your car on the ydno.

I just don't see why you guys don't see an ECU as being capable of being ROM tuned on a dyno vs. a standalone. Yes, might not be an option for everyone, but there are more people out there that can tune Nissan ECUs than most think. I do agree that having something dyno tuned is preferable to a remote tune. I always want to see exactly how the car is behaving before going past a certain "point."

I have gone plenty of times past 110 in my 240 and never had problems with stability however the fastest I've taken it has been up to 140mph. Perhaps having a wide body kit, coilovers and wider tires 17x225 & 17x255 helps.

[blu808]

Prob. I used to drift my s14 at 110Mph no problem. But if I take my stock beater s14 on the freeway at 110mph I feel like im gonna die.

Again setup.

My ls1 turbo fc cant go straight at any speed under 140mph. Any speed over that is just ok. If I hit a little bump im dead. No question. Dead! The amount of unloading done by the tires, and suspension will ruin your day. lol

[s14unimog]

get a bike and stop driving your 240 that fast
