This is a moron question so bare with me. I sound like a fast and furious kid, I know but I was reading though the honda prelude manual for my 95 base model and I see that the gearing is much higher then the si and vtec models, would that lead me to think that the acceleration wasnt a issue and it was just how high could the top out would the "S" top out higher or the vtec. I have driven a 4th gen vtec and its incredible but as for top speed...?
I have driven a friends "S" model and I hit 120 in it but that seemed like that was all she had even though it didn't redline it was out of power. But I have topped mine a lil over 130 and quit. Hope that helps a lil.
I believe the VTEC hits redline in 5th at 142mph. From the way mine pulled up to around 130 I'd say it would have plenty of go left to make it to 142, but I've never been quite there. I always seem to run out of open road or balls before I get all the way to the rev limiter
Originally posted by schrunk what was your model that topped out at 130?
That isn't what she topped out at that is just where I quit because that is lil to fast. I drive a boosted H23 and From where the needle was I think I could have hit about 135-140mph.
The base model gears are longer than the Si and VTEC so theorically it could get a higher top speed but it would probably need more power too.
These are the theorical top speed at redline:
S: 152.1MPH
Si: 132.0MPH
VTEC: 144.1MPH
The VTEC can only get a higher top speed than the Si because it's redline is at 7600RPM instead of 6500RPM. If it was limited to 6500RPM like the S and Si, it's top speed would be 123.2MPH
If a Si would have the same redline as the VTEC it's top speed would be 154.4MPH and if a S would have the same redline as the VTEC it would be 177.8MPH but then again it would also need the power to get there...
A friend of mine has a 93 Accord with an jdm H22a with the accord tranny and we did a top speed run on the dyno and his car hit dam near 180. It would never pull this on the street due to weight/aero dynamics, but the tranny/motor combo is capable of it. Here's a video. http://www.h22a.org/BS/topspeed.wmv I'm running a JDM h22a with a 93 p14 tranny and the car hits the stock speed govner in 4th gear. So I can see 150 or so being easily broken with this setup minus a speed govner

Yeah the Accord tranny is pretty much like the Prelude S that is if it doesn't have a longer final drive... so 180 would be possible to get but he'd need a lot more power what a stock H22 will give him...
Depends on the tires you have I believe 215/35/18 are the closest to the stock size look at the Tire Diameter section on www.preludecrazy.com If you tires have a larger diameter than the stock you then you're going faster than what's indicated if you have a smaller diameter you're going slower than what's indicated. But also keep in mind that the tach isn't that accurate, especially at high speed
There are two main factors to consider when determining top speed: aerodynamics and horsepower. Given that the VTEC Prelude has more hp than the base, I'd say that the VTEC one will top out higher. Yes, gearing plays a part, but mainly just how long it will take to get to the theoritical top speed.
I read a Car & Driver a few years back and they topped out the 4th gen VTEC at 140 exactly. I read (not sure about this) that the 5th gen's given their new shape and 5 more hp can hit 142~145.

where did you get these numbers from? at 6500 a si is at 127 so it can go a bit higher because fuel cut off is at 6800. i calculated this all out before and thought a vtec hits revlimiter lower than 144.
I used the www.autocrossing.com gearing calculator. Also don't forget that the stock gauge is off especially at high speed. I remember my Si the rev limiter was a bit over 6500RPM but I don't know what the offical Honda number is. Like if it's 6500RPM then when you hit the rev limiter at 6800RPM you're really at 6500RPM or whatever what's the real number. So I think those numbers make sense.

Speedo said ~125mph.

My Garmin eTrex is accurate to .01mph
I can actually hit the speed limiter in 4th gear.
Damn JDM limiter!
Since you have a JDM ecu, 112MPH seems right since 112MPH = 180KMH which is where the speed limiter is in the JDM cars.
