That's why most Honda and Toyota VTEC fours are so sluggish at low speeds....the combustion characteristics inside the cylinders give mostly high-RPM horsepower and very little torque. Wind them out to 6000 RPM-plus, and then you notice a difference.
I have no idea how much torque it adds, thats why the dyno will tell. no other way to measure that.

I don't mind big horsepower SUV's. There are plenty of them safely on the road. The key is not having so much horsepower it's stupidly exceeding what the thing is capable of handling.
Look at the great Toyota tuner Gadget. He's built several 850whp+ 4runners. All were detuned down to 500-600whp. I have nothing against them. If O***s want to build some with 300-500 flywheel horsepower, they need to give them good suspensions, electronic trickery to keep people out of endless trouble & chassis that can handle it.
I had a buddy in college who use to auto-x his Jeep Grand Cherokee. It was quicker than some things (mild suspension upgrades) without any handling problems. (Other than expected, being a 2 ton SUV) It had around 300-320 horsepower.
If anything, all these 300-350bhp S/C 4runner/trucks & upgraded v8's of all kind with more than 300bhp are LESS safe than what the O***s would deliver with 450-500 horsepower.
I see no problem with any of it. If anything it's a hell of alot safer than the alternatives.
Neons are the worst thing out there.
The only thing worse were the early, early sunfire/cavy where you had to drop the engine to change the spark plugs because they shoved it in too tight (& we complain about the v6 Camry platform rear bank!)
SRT-4's are a different breed. While the stock 2003 isn't any faster than most modified/good output v6 Sedans, the 2004+'s will eat them for lunch @ corner infinitely better stock. God forbid you forget that checking off a few items from the factory MOPAR book will give you 400hp+.
At the end of the day the only important thing is wheel horsepower to weight ratio.
Torque is meaningless when trying to find something useful to know. You can't, with any precision, derive ANYTHING useful from a torque as a number. It is simply twisting motion. NOT acceleration, NOT speed, not even towing ability.
Horsepower is all that matters. Think I'm kidding? Simply look at what they are:
Torque can be thought of informally as "rotational force".
Horsepower is torque applied over both TIME and DISTANCE.
You can calculate, with precision:
Acceleration
Speed
Pulling ability
Fueling
Timing
Everything under the sun to do with the charge & it's flow.
All Horsepower. What can someone find useful to figure out with torque? Horsepower, anything else? No, everything useful is derived from knowing horsepower.
Again Horsepower = torque (Rotational force) Applied over both time & distance. In the end, all that matters is how much horsepower there is at the given time you want to have it.

15.6 stock, 15.4 for him sounds in-line with me. Admittedly I don't know that much about escorts...
AFA Army's escort goes, it's had enough & the right kind of mods to do what he told you he has for peak power. I'm sure if you were to find a bigtime escort website with some people on it that really know their stuff, you could come up to what he's talking about.
(Then again If josh would get a clutch that wouldn't fry on a big time launch, some slicks & learn to drive!!!! I don't see why he couldn't trap mid 14's. Every Honda I've ever seen with "relatively" low power, a strong clutch, warmed up slicks & a bigtime drop could do it)
It doesn't take power to run a good 1/4 mile. If it did stock Supra's, Every lexus car, Mitsubishi 3000 GT's, semi-trucks - (Just examples people) would all trap fast numbers. As it stands, they're not faster than many current sedans with a few mods.
It takes horsepower to weight. That's why every **** any 200-250bhp i4 N/A Honda with **** for torque runs 13-14's.
Hell at 200-220 horsepower most "run what you drive" A/T sedan/lexury cars are doing good to make 16.000.

15.4... in your stock 2 liter sohc 110 hp ford escort? do you have a time slip? is your car stock?... Edit I see some mods but I still question the time posted... maybe on a really cool day depending on location....
1998 Ford Escort ZX2 7.4 15.7

Thank you. 15.4 is nothing surprising, in fact, i was suprised how high the Number was. that was run when i still had the Goodyear eagle RSA's on the front, and i couldnt hook up for ****. I peeled through 1st and chirped in second. it was a bad run, but good enough to know that the car is quick.
the clutch is fine and will continue to be, it was engineered to take 200+HP dumping it at 5k all day long.
. when i hit 200+, stage 3 triple plate kevlar or ceramic clutch will go in, along with the new tranny i have in storage for it, its got steel synchronizers and better forks..
