Stock spec v times

[slideways...]

theoretically, the only reason to get a smaller exhaust is to make full use of the scavenging effect of the headers, ect.

i have yet to see any proof that backpressure is needed at all for power...and i have seen dyno pulls on nearly stock hondas, ect. with nothing after the headers and power + torque is gained over a cat-back through the ENTIRE powerband

driveability is another issue. with no backpressure your car will run rough at idle.

what is the ideal piping size for the spec?

2.5 inch NA.......3 inch FI

No a newer Prelude cannot take a SPEC-V I had an Lude thank you, and the Spec-V is up on it. There is another post on here as well that goes over it and there is a concensus of about 18/20 people that the Spec will take the Prelude.

Sorry, just aint happening. The Prelude has nearly 50hp on the Spec, a redline that's nearly 2000rpm higher, and super SUPER-short gearing. It's a FACT that 1997-2001 Prelude SH's run a 15.0-15.1. A stock Spec is almost half a second slower. If anything, the Spec would have the Prelude through most of it's first gear and that's it.

[nismo_pilot]

then why did my stocker V crush a 99 lude with intake and exhaust, hondas make their power later in the band, by the time he shifted out of first i was already halfway through 3rd and pulling, that extra 50hp isnt made until higher in the band where i was already gone, it might take the spec from a roll where he would go right into peak power but other than that the lude loses dude. if the prelude made that power earlier in the band he would have stood a chance.



(before the flaming begins yes he knows how to drive, i taught the dude how to drive and he shifts exactly like i do so there isnt too much driver error)

[fugiot]

First of all, this is the H22 were talking about here. Not a B16. The torque curve on the H22 is VERY similar to the SR20VE's which is almost completely flat.

Second, there's no way you were going over 70mph by the time he barely got to 35mph. There's was something really wrong with that race.

Third, your story reeks of total horse crap. The Spec is an awesome car with a lot of potential, but it's not to be put on it's own shelf and be called invincible. Shit, a 1996 Buick Regal or an '89 Ford Taurus sho could beat a Spec. The Spec only bests a 138hp Ford Escort ZX2 by 0.3 in the quarter.

[Rowens V-Spec]

With all respect the escort only has 127hp for the GT had one of those. The prelude does have about 200+lbs on the Spec-V, and approx 20 hp, but lacks about 20lbs of torque too.

Just the numbers alone there says the Spec-V will win.

An extra 200lbs with only 20xtraHP and 20lessTq

Sounds close, but sounds like the Spec-V will win
Now to my knowledge this isn't the SH i don't know too much about it, but i know based on the SI Vtec H22 motor in it. I feel the difference. I just bought my Spec-V, and I got rid of my prelude last year about this time. I can't directly place the feel of it, but i can say. I feel as if i have a noticeable feel in the Spec-V than the prelude.

If you would like i will hit the track with my friend. He's got the 00' Prelude

[fugiot]

yes, but the only power you can FEEL is torque. You can't feel HP. It creates more of a "floaty" feeling than a pulling feeling. You're also forgetting of the MAJOR advantage that gearing provides. A Spec redlines at 6200rpm@38mph. The Prelude reds at 7800rpm@35mph. That's nearly a 2000rpm difference at the same speed meaning that the gears in the prelude are incredibly short. Shorter than even a B13 SE-R's. Now a weak power curve(if the H22's WAS weak), would only matter in 1st gear anyway. But since 1st is so incredibly tiny, it flies to redline before you know it. Smaller gears make the car seem dramatically lighter to the motor.

One thing I will say though, I'm sure the clutch and the low-end power in the Spec are better. It will definitely have the initial launch. But here's where things get tricky...the Prelude is meant as an "entry-level luxury car". If the Prelude has a terrible start, it won't catch up. Whereas the Prelude's 1st and 2nd gears are super tiny for around-town acceleration, it's also missing a gear to the Spec's 6-speed. The Spec is geared just like any other compact until 4th. 4th is a real small gear on the Spec and will pull HARD. I would actually be more inclined to believe the Spec winning from a roll or passing the 'Lude farther into the race(despite the trademark VTEC top-end), but not spanking a 'Lude in the first 2 gears.

[Rowens V-Spec]

I think we can agree on that, I'm not saying a Spec-V would spank a lude, as i refer to it as. But I think it would take it. And yes those High RPM's matter alot, but if you can really run through those gears on the 6 speed it well compensates. It is a tough match on paper, and in reallity, but i'll stick to my guns on the Spec-V, but a good argument either way. I think we could agree that much?

[fugiot]

Definitely good argument.

My voting in a race would be like a 60/40 - Prelude/Spec. Tough call. Especially when I remembered that the Preludes don't have 220hp.

[Rowens V-Spec]

Your thinking of the famed but rare as hell H23 Vtec in the JDM accord wagons. They got 220, plus if you put the ingenuity to it, and frankenstein the H23 block to the H22 head you get that HP too. Honest mistake man.
I'm not so much of an ameteur. I just am not as well versed as everyone else. I normally do a hell of alot of research on what i want before i buy it though.

[fugiot]

Naw, I was just thinking of a plain old 3rd gen Prelude. The number 220 was just stuck in my head for some reason. Never heard of the vtec H23, tho. Only the old 2nd gen 'lude's 160hp H23.

[Rowens V-Spec]

Ah, well being that I had a prelude, I had to be an enthusiast, and i got ito some deep research about it. You know how rare Accord wagons are. Not alot of them running around. So in Japan even less, and they carry the very powerful 220HP/167+lb H23 VTEC engine in it. Hard to find one at all. So most people make them by frankenstein the two, of corse you have to make additional oil ways in the block, and your good. Trust me I know my Ludes
hehe

[nismo_pilot]

have you ever driven a spec fugiot? granted i respect your opinion on things much more than anyone elses save slideways, but the spec pulls like a down syndrome patient at any speed over 65mph, also half way through 3rd puts me at about 55mph not 75......as for the h22, yeah its nice, but ive beaten one dropped into a crx hatch with intake, that motor is nice but not nice enough, and yes i know the spec gets beat by plenty of things, hell ive been pulled by a damn vibe gt from a roll, (we were doing about 80 though and i already told you about the down syndrome thing), drag racing is about initial acceleration anyways, ever watched a pro drag? they make 80% of their top speed before half track, the more power you put down earlier in the race, the better your chances of winning, hondas are not made to be drag cars. Period.
