Top speed
 

After researching Ive found that a bone stock FD has a top speed of 160. (170+ for Japanese models). Does anyone know if this is from the motor at redline, or limited by drag. If so what would the top speed be at 8000RPM (or more)?

If you had the ability to wind it up that far it may reach it...But the rx7 world record is 242mph

The top speed is limited by drag. The USA 5th gear tops out right around 200mph, but you will need quite a bit of power to get there.

honestly if i can hit 160-170 lol i doubt id have the balls to go faster than that..

i hit 150 once and i was crapping myself and i still think i coulc have went faster! i was scared of a deer or something running in front of me..

(this was done on a side road where nobody was) friends were at each end so nobody was going to drive ont he road for that 5 mins we had it.. everyone does it and the cops dont mind either for some reason they even come to watch sometimes and radar us just for fun.. no joke!!)

I assume we are talking about 170 Mph? If so, that's pretty good! (I'm a Canadian living in Tokyo we do Kph here!)

And why would the JDM version be faster?

Well, here is an FD going 215mph. Pretty sure it is a heavily modded 13b. It had a few aerodynamic issues.... :hahaha:

If you look closely you can see the front left corner lift.

top speed at redline is 202mph with non jspec gear ratios

doesn't the JDM have a speed limiter of 180 kph? i know the speedo only reads up to that speed and i've heard of a fuel cut but not sure if thats only on FCs

perhaps the stock ecu has a cut off.. but im sure if you upgrade that you can go as fast as you like..

The JDM cars have a shorter 5th gear than our USDM cars. At 160mph this allows them to be at a higher RPM which means the JDM car will be making more HP and thus will be able to reach a slightly higher top speed.

This is assuming that the speed limiter is bypassed, lol.

All JDM cars have a much shorter 5th gear. I found this quite annoying on long drives. My 180SX was always above 3800rpm at 65MPH. They gear there cars to be most fuel efficient at 85 kms/hr (53 MPH) as their max speed limit is 80kms/hr.
Their fuel cut is at 180kms/hr and at 107 kms /hr there is some stupid chime that goes ding *ding *ding until you decrease speed to 105.

All FDs top speed is drag limited.

when my car was almost bone stock with just intake and catback i got to a little over 160 after my car was done with a little bit of modding...... 170 and i ran out of room those tailights started getting close and getting there fast. i think i could have went a little more i dont think ill try it again 170 isn't too bad right :wink:

202????????
In your dreams. You can't even pull redline in 5th gear.

Reminds me of a bunch of high school kids trying to impress each other.

Heck the speedo goes up to 180, it must go that fast.

Published FACTS

Road & Track Feb 1992 issue..........

Top speed 159 mph (you need a mighty long & wide road to do it)

April 94 issue............

0-100-0 19.8 sec

To put it in prospective.....

A 2006 Porsche Carrera GT weights 3043 lbs & puts out 605 hp.
It only manages a top speed of 205

This kind of crap should be in the lounge

Theyre talking about mathematical top speed based on gear. Someone already posted that to reach the gear limited top speed you have to have a LOT of power. Theoretically 5th gear at 9k rpm is mathematically 200ish.
My old FD only had intake and exhaust, + downpipe. It certainly did not need a whole lot of room to hit 160, or about 6500 rpms in 5th. Had it up to 7200 once and its right around 167-8.


You are magazine racing. Not much better.

I took the fd on a road trip this past weekend and got her up to 110 several times but noticed strong throbbing engine vibrations coming through the engine bay and had to pull the plug. Honestly it didn't feel like it had much else in it. I guess over 110 ish you just need a LONG road to get going.

Something is wrong with your 7. Mine would pull smoothly up to those speeds. In fact if all you can do is 110 than you arent even getting out of 3rd gear... change to 5th at around 145-150mph. Still pulled, not as strong but Id say 10 miles an hour climb in around 7 or 8 seconds at those speeds.

110 was attainable in a standing 1/4 mile... Not much room.

i pulled to 140 nice and clean once, could gone faster but eitherway it was still smooth as silk at that speed.

i think i read that the JDM 5th gear will only reach 182mph instead of the US 202mph. theoretically that is.

Fastest I'd ever gotten mine when stock was around 155, this was with a long 3 - 4 mile run. I've not "topped" it out with my new engine with all the mods, all I know is 145 comes up REAL fast, and...I just don't have a whole lot of reason to run much faster than that.
I must be getting old....

take a look at the speed! IN KMH! 282=176mph!
this was 2 months ago. & the car kept going but it stopped there (thinking the motor blew. But it was a spark plug!




NOW THE SPEEDOMETER WENT PASS THE 180 MARK SO I WAS HITTING 182 (POWER FC IS OFF BY 6MPH)

forgot to mention I have an auto.

I have hit over 175 mph in a basically stock FD it felt good too, only think that felt better and went substantially faster was my yamaha R1, 187mph and it was SOLID, like i was on rails!!!!!

i never said it would get there... all i meant was at red line the car would be doing 202 in 5th


by the way i've done 180 in my FD

the pfc is reading correctly. you cant trust your speedometer at that speed. you must have hit your limit. we had a thread discussing this very topic a few months ago. i am shocked noone just posted that...

I know I did between 155 and 160 in mine with pettit ecu and bolt ons.
