Bhp Or Torque???
- Thread starter VtecTurbo
- Start date
hmmm thats what i thought too, well me and a friend have compared our cars, a 1.6 producing 160bhp and 120ft lbs of torque with a 2.0 150bhp with a 135ft lbs of torque, i thought that the 2.0 150bhp with a 135ft lbs vehicle would be alot faster after the first 2 gears, keeping in mind that they were both stock engines with similar shassy weight, its kind of confusing sometimes deciding whether a car with more bhp and less torque or a car with less bhp and more torque would b faster
pink_floyd what is your problem!!! nobody is forcing you to read these posts, its your own choice, by the way if you know how to read its BHP OR TORQUE, not BHP VS TORQUE.... FOOL! and what you talking about i never posted anything about vtec vs vanos, i think you've got something stuck up your backside, you better watch it or il force that thing up their further and cause u serious pain!
Take it easy “tough guy.” If you want to post your questions that’s fine, but don’t start insulting people. Unlike other places you may visit, this is a Family, we may have differences in opinion but insults are not welcome.
Just as panzershreck said they’re equally important, torque gets it’s started and HP finishes the job.

hey Ghost, i agree with you that this place is like a family, i said that in the other post but some people jus want to argue, im cool with everyone but this guy has been testing my patience! hes been calling me a retard n swearing at me in other posts, there was no need for it, obviously a man isnt going to keep taking shit!

I need both. My friend's GS-R is fun, but around town, I can get smoked by trucks/suvs cuz there may not be enough room to hit the high revs. When I had my Jeep, I smoked pretty much every Honda/Acura I came across at the stoplights cuz I had so much torque (after abotu 40 mph they'd kill me, but we have some short blocks in some areas where it's hard to get that fast).
My other friend had a Z28 Camaro. Tons of fun down low, but no upper range.

You want both, that was an easy answer. Cars with equal or more torque than hp will generally pull longer through the RPM bands.
I will use my car, and my best friends car as a comparison for ya (minus my mods);
A stock 323 3 series BMW - 170 hp, 182 torque - power band is 3000-5500 RPM, steady heavy pull. Redline at 6500 (on a stock car)
A stock Honda Civic si - 160hp, 132 torque - power band is about 4000-6000, pulls, then hits it's higher band and gets a super burst pull. redlines around 6800.
We used to run about neck and neck before I did a few things, his car is a great deal lighter for one, and when he hits his power band, he really pulls harder than me, whereas mine is a more constant solid pull once you hit the band.
Thats about as good as I can give you hp vs torque. You want both, and if you live in the mtns, you really want alot of torque...![[:D]](/images/smilies/biggrin.png "Big Grin [:D]")

Just quoting Honda's website, and my friends odometer and his reports to me. ![[screwy]](/images/smilies/icon_smile_screwy.gif "Screwy [screwy]")
But yes I believe he's a dohc vtec. (2002 civic si hatch) He has that down his bottom door trim if I recall correctly (he has 'SOMETHING' and Vtec on the side..)
So what you're saying, is that YOUR civic si w/ SOHC Vtec doesn't redline till 8000. What's the hp/torque for your car, different engine than a DOHC, or FI going on, or...? (Curious about the sohc, but not enough to go look again..)![[;)]](/images/smilies/wink.png "Wink [;)]")
Not looking for a chapter, but what are the differences from a SOHC to DOHC?

dohc means double over head cam, which means you have to camshafts working in an engine, sohc means sing over head cam, which means 1 cam working in an engine, yea my car is an dohc vtec, over here in the u.k they are called "vti vtec", in places like japan and america they are called "si vtec's"
Basically the dohc vtec produces 160bhp and around 130ft lbs of torque, im not sure about the figures on the sohc vtec but its alot less.
the dohc vtec si has a rev limit of 8500rpm, vtec engagement point at 5500rpm and start redline ar 8000rpm
the sohc si has a rev limit of 7200rpm, vtec engagement point at about 5000/5500rpm and start redline about 6500rpm

I only read the first post, but I'm going to say this: both are very important, but horsepower is more important.
Horsepower determines the car's rate of acceleration and torque determines the car's ability to accelerate. Torque becomes more or less important depending on the situation, but ultimately horsepower is the key to determining a car's 0-60 and 1/4-mile acceleration times.
Let's take two cars:
Car A: 200hp and 150 torque
Car B: 175hp and 175 torque
Let's assume that both cars are the same in terms of gear ratios, weight, tire/wheel setup, suspension, transmission (gear ratios), etc.
If racing on a flat road, Car A will be faster because there is more horsepower available. If racing on an uphill, Car B will probably be faster because that extra torque will help the car accelerate under heavier load. This is a general example with very general numbers but it's hard to be more specific.
Keep in mind that top end horsepower and top end torque are not the determining factors. It's also important how much horsepower and torque each engine produces all the way through the rev band. Now that I think about it, my example is probably not very good but I'm trying to make the point that torque matters depending on the situation.
There is a lot to this debate that I don't feel like explaining right now...lots of different things about horsepower and torque that you need to understand. Maybe I'll explain them later if I feel like doing more typing.

i totally agree with your point, but its just sometimes people confuse you, thanx guys for you replies i really appreciate it
