I just test drove a 1997 VTEC Prelude. I can't say I noticed any huge performance gap between it an

The last time I drove the new Lude, the Vtec kick-in was dramatic. But the car had a cold air intake and
performance exhaust (and dropped). In fact with the Lude, gearing from 5th into 2nd gear (which
instantly took the rpm to over 5500rpm) was more impressive when compared to RSX Type-S in the same
situation. I suspect the Ludes more sporty response was do to the minor performance add ons. However,
even with the performance add-ons, the Type-S was all round faster (being able to hold the Vtec till
8000rpm instead of 7000rpm makes a huge difference).

Obviously, the 97 Lude that you test drove is not a good example of that model's ability. Personally,
I'd take the 95 since the interior is more reminiscence of the CRX and the seating is more suited for my
larger frame.

Just compare the maximum torques per engines specs, you'll see the
extra torque is <3% if capacity ( cc ) is constant How can a little extra
torque give any *huge performance gap ? You need to drive a MaClaren
to get a *.
Even iVtec is insignificant compared to e.g. Saab's turbo or Mercedes's
super charger ( 12% extra torque ). Just a set of high efficiency plug
cables on my buddy's 9-97 CRV gives 15% extra torque.

Amazing.
Where did you dyno it, and what where the numbers?

Dunno if you missed it but this is the guy who goes on about all the power
lost to the digital clock.

Yeah, I know.
And battery terminals made out of copper and not silver.

I can never remember what name he posts under.

That's because your "buddy" is either a lying shite or he didn't have HT
leads / the old ones were buggered before he put the high efficiency ones
on. Tell him to compare his "high efficiency" leads to a set from the Honda
parts desk. Go and dyno the car and you will find no difference in power
beyond normal dyno errors.

You can put a massive coil on the car, or put shedloads of coils on, but as
long as your existing ignition system works, you won't gain any extra power.
The only time you'll need to put a different ignition system on is when
you're increasing the revs, so you need a spark more often, or you're
altering the charge / plugs so that it's harder for the spark to jump the
gap. You don't get any extra power to speak of on a modern normally
aspirated engine without messing with the internals.

Anyway, everyone who knows anything knows the point of V-tec is to switch to
a lairy cam at high engine speeds, so that you can have good low speed
running and fuel economy when you're tootling around town, and then when you
want to go fast you get some revs on, the hot cam comes on and you get more
top end power. It's all about the revs (and thus power) in a V-tec motor
rather than providing torque. If they were about torque they'd be 4 litre
motors instead of 2.

I suspect the difference between the Prelude and the RSX was because of the
differences in way the V-tec system is set up in both cars, rather than the
exhaust and intake fiddling.
The RSX is the Integra here in the UK, and it's a much sportier car than the
prelude. From what I understand the Type S is a slightly detuned Type R (the
hottest Integra/RSX) so that it can run on lower grade fuel. I'd expect the
standard (ie, pre vtec switch point) cam in the Type S to be designed for
more power than the standard cam in a Prelude, so the V-tec kick in the back
will be less pronounced.

Amazing, really. There's Honda spending, well, must be into the billions on R&D
to squeeze out maybe 1% extra torque here, or a few more bhp there, and all the
time all they had to do was put phat leads on to get a fifth more grunt.

Next, they'll add the magic air filter and double the power output.

Prelude may be too much car to feel any diff.
Try a Del Sol VTEC if you can find one. You will be surprised what a
difference 200 hp in that little thing.
