1999 Explorer ---Saleen XP8

ChuckyD, you have a good point there. I was only generalizing in the area of unmodified large blocks to unmodified small blocks. That S2000 is high tech and the 4.6 is not so it is a bit unfair, but you still do have a point about size.

You do the "identical" build on a 4 l motor and on a 7 l motor and see which one makes the most HP?

youre missing the point i was trying to make (though, i dont think its possible to do an "identical" build on a 4L ford as on a 6.6L pontiac.) i was just saying that displacement is not the final word. if someone has a pontiac 400, that doesnt mean its going to make more power than a, say, blown 350.

now, in theory, as far as an "identical" build goes, maybe youre right, maybe not. a 4.0 from a jeep cherokee has ~190 hp (or something like that), right? and ford has 2 4.0 motors; one makes 160 hp and the other makes 205 hp. yes, theyre all different setups (in line 6, OHV, and SOHC), but theyre all the same displacement.

Then there's Explorer Express

If you take a stock 5.0 X and add their supercharger and handling kits for appox $5,100. You get 0-60 in 7.3 and 8.2 g's!! (From Motor Trend)

That doesn't include any aero add-ons and thus it doesn't look as nice as a Saleen but hey, looks aren't everyting.

Too bad I've got a 4.0 OHV.

erg.. er, where are you getting your numbers??

the numbers I've heard for the s2000 are: 0-60 in 5.5-8 seconds, and quarter mile in the 14s. Those are the real numbers that I've seen at local tracks.

motor trend pushed a 99' stang gt, convertable even: 0-60 in 5.4 and 1/4 of 14seconds flat.

I can vouch for those numbers too, I've driven both of those cars several times, and they aren't that slow at all. I'd be embarrassed to deliver a 7 second 0-60 in either of those cars

Take into consideration weather conditions... aside from that these times change all the time when magazine report on them... as far as the track goes, your saying those guys that have these cars didnt do a thing to them? Exhaust or intake which are both very common in those cars especially!!

You are missing my point, I am afrade. I am simply saying that if you do an identical build up ( and of course it can't be identical ) on a 4 l motor and on a 7 l motor, the 7 l will produce more HP. In this build, both motors will be blueprinted and both supercharged. In this case the larger displacement will simply make more HP

Well, both sides of the argument can be.. er, argued.

As in, "there is no replacement for displacement," and "the replacement for displacement is technology." Both are true.

Ex., 1975 Corvette with an L48 engine (350 cubes) made 165hp@3800rpm and 255tq@2400 rpm. My explorer with the OHV 4.0l (243 cubes i think) makes 160hp and 220tq (not sure what rpms). 100 less cubes, yet very near same power.

So what I'm saying basically is that the best combination is technology and displacement -- can't go wrong. A la chevy's LS6 for example.. 5.7l with 405hp and 405tq from an extremely technically advanced OHV motor, I'd say about as much technology as you can put in an OHV motor, and with excellent results.

times those bad could only be contributed to er, rain or snow perhaps when it comes to weather conditions? or the driver..

As for those times, yup, those are stock times. Even down to the air filter. Friend's dad has an S2000, bone stock, and can pull those times.. talk about a fun car, handles great, nice little roadster, but anyways, thats a different topic. As for the stang, yeah, motor trend doesn't modify the cars for tests, other than testing eqiupment put on the car. They do have to return some to the manufacturer (with the exception of long-term tests, etc.), so its not like they're allowed to modify them.
