acceleration

[Racing Rice]

Dez is right.. Its very hard to get improved 0-60 times without doing FI. I really doubt that I/H/E will help your 0-60 times much if at all, they could even hurt 0-60 times depending on what products you get. You want something that will give you lowend torque (which we all know is a problem in FWD cars..)

Turbos will help if you have a turbo with little or now lag. If your turbo is to big it will cause to much lag giving less lowend torque, because you are using exhaust gases to spool the turbo. The smaller turbo the faster it will spool up.

Superchargers are nice in that the fact the power is instant when you stomp on the gas. The problem with SC's is that they arent as tunable so you cant just crank the boost up changing turn the knob on the boost controller.

Nitrous is a good cheap way to add quick power but wont really help you out much when it comes to 0-60 times either. you only want to use N2O when you are WOT (wide open throttle) and over 3000 RPMs or so.

But to get cheap lowend torque, I wish I had an answer for you.

hmmm.... bummer, cuz low-end torque is what I like. Guess I should just go buy a torqueyer car eh? how good is a crx compared to a civic in LET (low end torque)?

thanks for the info though guys

[flylwsi]

well...
on a 3 gen prelude, cam gears are good for ten ft lbs of tq up to 3500 rpm... that is pretty good lowend pickup...
it just depends on your motor...
as previously stated, you have an econocar...
my prelude is a sports car, and a civic si is a sporty car... vs a dx civic... it is harder, but it is doable...
for example...
you get more lowend out of a cai, and headers are usually good... as well as a well designed exh
another thought is a lightened flywheel which will let you rev quicker, getting to the power quicker...
or you can launch at higher rpms...
if i am racin it on the street i launch much higher than if i am just drivin... gets me into the power quicker... its more in how you drive/take advantage of the power you got...

for example... if you are a better driver... you can take a vette off the line, b/c you may have better skills launching or reaction time... however, b/c of the sheer power it will eat you up...
but at least you know you got him where it counts.
any nerd can drive a nice car...
but it takes a good driver to use a car to its full potential

ALSO...

SPORTS CAR W/350S HAVE NOT BEEN THE NORM.
THE NORM HAS BEEN SMALL LIGHT CARS. LOTUS. FERRARI. JAGUAR. CARS LIKE THAT ARE THE NORM. YOU ARE LOOKIN AT AMERICA. GREAT. LOOK AT THE NORM AROUND THE WORLD.
NOT TO SAY A 350 IS A BAD MOTOR. BUT THERE ARE LOTS OF LITTLE MOTOR CARS THAT WILL KILL A 350 POWERED CAR, TRUCK, OR WHATEVER. PLEASE DONT BE AN IGNORANT DOMESTIC OWNER.
OH, YEAH. IM NOT SAYING YOU ARE. SO DONT FLAME ME. IM JUST ASKING THAT YOU OPEN YOUR EYES TO MOTORS THAT ARE HALF YOUR SIZE. WHICH ARE MUCH MORE ABUNDANT THAN WHATCHA GOT.

AND ONE MORE THING.
SIZE AND POWER DONT MATTER.
POWER TO WEIGHT IS IT MAN. I DONT CARE HOW BIG YOUR MOTOR IS.

Im glad we found that key

lightened flywheels on cars that are not F/I or high N/A tuned are not a good idea, unless it is a track car. There are risk factors to look at.
Cam gears for a SOHC is worthless, even cams w/ adjustable gear tuned on a dyno will be hard pressed to produce more than 5 useable HP.

What kinda of risk factors? I know about the RPMs falling to fast, and could make your car idle rough.. What else would it do?

They are the exact same.. The only difference between the 2 is the fact that the CRX is lighter then the civic. Now If you put a prelude motor in a CRX you would have a beast on your hands. The power to weight ratio would be unbelievable. It would make a perfect strip car. Wouldn’t be to great on the road though because the motor weighs so much, your weight distribution would be crappy.

sweet! I'm gonna do that! and to balance, I'll put some lead weights in the trunk! heck yeah! w00t!!!

Well, lightened flywheels on a car w/o a lot of power, namely our Civics, can cause some lagging low, that will cause us to rev higher to get the car going. Aluminum flywheels have a tendency to warp, which is dangerous, unless only track driven, warping is very common in the race field and scatter shields are a must, unless you want your trans blowing your chest off. The Chromoly steel flywheels like Jun have had problems with cracking due to the starter gear, an once those flywheels get a chip or crack, you are in trouble. Would you want your flywheel cracking in haldf in a trans spinning several 1000rpms?

thanks...
i reply at werk, and i am always in caps here...

No need to go for extremes but a slightly lightened flywheel will help.

Any body here weighed an H22A compared to a B series motor, it is heavier but not by enough to make a huge difference. Its just all that power in suspension thats not designeed for it...in a quality install with the suspension suitably modified it will not be a big factor

Its a good thing that I asked then..because Ive never heard that.

america doesnt have sports cars per se. that is what i meant. mustangs etc are muscle cars. there have been enough big motor mustangs through my garage to know that.
if you have seen my posts anywhere on this site you will note that i am not biased. but the simple post was that sports cars are not generally 350 cars. maybe here, and then those arent sports cars. they tie into the pony car/muscle car image. and the vette... that is a bit above a sports car. if anything, though, it is the closest.
to me a sports car is something along the lines of an old lotus or a small light weight car with a motor to match the car.this means that power to weight is the key. but that doesnt mean i dont know what a 5.7 is.and the corvette, which is actually smaller than 350, and has been for a while, weighs in at 5.3 liters.
also... find me a sports car made right now that is from chrysler with a 318 in it... the closest thing is a dakota r/t. which is not a bad option.
this is not a knock, just stating that i know my shiet and i dont post things like that w/o knowing both sides.

thus stated...
the sports car here is a muscle car. the rest of the world, however, runs around in smaller motor cars that have great power to weight ratios or turbos that kick all sortsa power. or in amazing little motors with some wild infinitely variable cams. like the porsche the ferrari and the bmw, not to mention vtec.
we americans are stuck on bigger is better.
until we get beat by a civic and scratch heads...

Good points flylwsi, I never really thought about it, but you are right, there are no "sports" cars made domestically here. Its interesting now that I think of it, just about every foriegn auto maker has the same basic lineups (SUV's, full/mid size sedan, smaller sedan/coupe) as domestic companies, but with one exception, they usually have a small roadster in the lineup as well. (theres your sports car )

Oh, and to focus on the question at hand, if you want more power on your Honda, forced induction seems to be the quickest way to do it. Supercharging may be good for you since you seem to want low end power, and SC's can offer linear power delivery throughout the rpm's. But dont rule out turbos, because Ive read that the right size turbo can perform just as well if not better, and turbos will always be more efficient. Finally, if you want more torque maybe a new engine is for you? Check out http://hybrid.honda-perf.org/ for info on that

[flylwsi]

thanks... i dint mean to put down american companies, but there are no true sports cars out there...

[Darkwing]

somebody mentioned changing gear ratios. will that work on an automatic? yeah yeah, I know, an automatic. It sucks, but I'm still learning how to drive. I'll get a manual someday...


edit: whoa! I just checked out that hybrid page! waaaaay to risky for me! maybe a heck of a lot cheaper for more power, but dang that's treading lightly on the legal stuff. If I'm going to have to go through a bunch of legal um stuff, to get a faster engine, forget it! I'll just take my little econo car and put put around town. I'll wait till I can buy a more legally secure car. holymoly...

Dodge Viper?
Chevy Corvette ZR-1?
DeLorean DMC-12 (I think that's American, GMC right?)?
Honda Civic? lol, just kidding

but the viper and ZR-1 are sportscars if you ask me!
