acceleration mod

anything (except charger, nos ...) increases acceleration ? i found tat boostin the top speed and hp is less of a concern since i'd rarely or never reaches the max ... so the acceleration seems more important ~

uummm any mod that you can do to your engine to free up or add hp/ torque will increase your acceleration. Intake/headers/exhaust are some easy to find bolt ons for ya if that is what your looking for

that's true~ it's a nice car...

anywho, basically:
1) reduce the weight
2) get the engine to suck up more air, and fart smoothly

hardcore get a SC or TC~ lol thumbsup

to accerelrate better you need more hp adn more torque.

so you need things like intkae exhasut btu won;t help that much to get a big difference you need something liek nitrous or a Turbo or s/c

Uhm, NO. I dont know where you guys get these ideas. Intake will increase acceleration- or TORQUE. Or LOW END TORQUE.

or you know what? This is just a stupid repost, I've argued this already here:

https://www.celicahobby.com/ubbthreads/thread.f_1870091434_2_collapsed_5__1.html#1870091434

and people have already demonstrated that they have no idea what they're talking about.

The smaller wheels is a good suggestion- people rarely want to do it but a smaller rotational mass really helps the get up.

Someone here suggested a Turbocharger for low end torque/acceleration and they need to be smacked.

Supercharger would be good. Intake as well. Headers and Exhaust cause you to LOSE low end torque and acceleration in return for more high end hp.

Header - we only have 1 not 2 happywink

if Intake and header cause you to lose low end power/tourque I mustve been smoking crack or something when I made this dyno sheet with header on a stock celica ..

Linked Image

looks to me like it gained both lol maybe I just read your statement incorrectly rofl

Lucky, Intake will gain you low end torque, but a larger exhaust will cause you to lose it. If you buy a higher quality header that provides for better flow than the stock one, you'll gain both. But a larger exhaust/too large of a header will cause you to LOOSE low end torque. You can laugh all you want, but you can make fun of a plural s I put behind "header" (although frankly, since they're four pipes, headers is quite a correct term. Especially since you can get 4-2-1 headers with multiple parts, etc etc.)

^^ I was just givin ya a hard time about the plural wink also I wanted to poiint out that you also were making statements that were broad and not 100% true cool gotta practice what you preach. I've seen you on many threads makin comments about peoples posts and its not cool. especially when you fall victim to your own insults thumbsup

Lucky, I didn't fall victum to my own insults, you said adding an aftermarket header got you a gain in hp. cool smile but if you add an aftermarket header and an exhaust that's too large, you'll see a drop in low end torque. The biggest difference your header makes (if you look back at your dyno chart) is the smoothing out of the power curves- do you see it? That stuffs all from imperfections in the stock headers etc etc.

plain and simple if you want to just acelerate faster you dont need the header and exhaust and pully Bull shit. just upgrade the clutch and get a lighter flywheel. it wont increase power but itll repsond and allow you to move from a stop a lot quicker.

you never specified larger exhaust you simply said exhaust. I dont have fact yet as that header is no longer on the car (should be back on soon that was a prototype dyno)

I don't use an aftermarket exhaust I simply remove the stock muffler. lol I'm willing to bet I dont lose low end power or torque. thats not counting what I can tune smile

you said that headers and exhaust make you lose power which if you have too large of an exhaust yes, you are right however I bet the right combo would make power or at worst stay at stock level wink If I am wrong when it comes dyno time then so be it. athough I've dynoed my car quite a bit with many variations so I'm quite familiar how she acts in different situations. smile

It looks impressive for a prototype- I bet the finished one will be better, those were some smooth curves.

Anyway, your type of exhaust really proves my point- you didn't increase the exhaust size; all you did was remove the stock muffler (which leads to backpressure, it does not help gas scavenging). Without doing anything to the size of the piping in the exhaust, you won't have any lose of torque- what you've just proven is that the stock headers really suck smile yay!

I'm sorry I never specified larger exhaust, but I dont know of anyone who'd do their exhaust without going a little big larger- I wasn't counting just changing the muffler out as "exhaust" and I guess thats my fault for not specifying.

Also, you've stated that you use one of the ECU mods to handle your computers power- was it on when you made that dyno? A powerful engine management system has the power to learn the exhaust etc pretty friggin fast, and almost negate the lag it would make- it happens on Turbo lag, exhaust lag.

aftermarket Throttle Rotor. Less time to WOT will increase your acceleration for sure.

Never mash the pedal, instead, roll into the throttle, if you don't bog the motor in low revs you will accelerate better. If you have serious mods, this may not be an issue to you.

get better tires, lighter rims, use weight reduction every time you can. Relocate the battery to the back of the car.

keep underhood temps low, as well as oil , tranny fluid & coolant tems low as well. use a slightly thinner synthetic oil to reduce friction and resistance.

Butcher-grind the crank to let the engine rev up quicker, if you can, mod the tranny (clutch and flywheel, LSD for manual and Torque Convertor, valve body kit for the automatics.

Dampen the engine with a strut damper or motor mount inserts.

Fold your Mirrors in, close the windows & sunroof. Increase downforce to the front end (use a splitter).

Lots more I can think of besides this, but it's all been said before.

Just throwing ideas out there.

You move the battery wires around? not that hard, just a pain..

Tho, rave, I'd like to hear your reason on why this increases acceleration? (i'm all willing to jump behind it and say it will, but I want to know why smile

Well, to be honest, it's not so much for increasing your acceleration, although it may help a little since the front end will be a bit lighter, but relocating the battery to the back will shift some of that excess weight to the rear of the car, it will definitely change the handling charachteristics, and lessen the understeer problems a little, which is nice while you're driving at speed; an even weight distribution is almost as important as overall weight reduction.

You want to acheive as close to a neutral weight balance as possible (the vehicle's weight is distributed evenly front to back) This is why some enthusiasts love the old corollas so much, it's got a nearly perfect neutral weight distribution.

Besides, relocating the battery will free up space in the engine bay, which is a must when you're trying to shoe-horn engine mods (or an engine swap) under the Hood. also makes your underhood temps a little lower. The race battery swap idea is cool too, but just remember that it's for racing only. Heck, you could relocate the battery AND swap it for a racing cell for the biggest benifit, weight distribution AND reduction in one shot.

Which reminds me, reducing under Hood temps goes a long way. wrap your manifolds/headers, increase airflow under the Hood, make a radiator cool panel, get a colder thermostat. I think it's something like "For every five degrees of temperature reduction under the Hood, it's good for about 1HP, so, if you reduce underhood temps by 25 degrees or so, you would notice an improvement.

Fuel pump, FMU, injectors, etc etc. Ignore those, and you're going to keep running lean. If you run lean with NAWZZZZZ it'll blow. For a Turbo or s/c you have to upgrade the entire system depending on how much psi you're running.

It's not a "big mod" it's just something that should be done on every car when you begin modding it to hp levels above stock.

That's assuming you are running a Dry Nitrous system, if you go with a wet system, fuel is not an issue (wet systems inject both nitrous AND additional fuel simultaneously when you are squeezing the bottle...)

Only if you are running a dry nitrous kit do you need to worry about fuel enrichment; it's already accounted for in a wet system.
