I have a manual 2.4l and it's horrible how hard it is to accelerate at low rpm..... especially while shifting from 1st to 2nd....

I have to go down in 3rd gear at 60 mph to have decent accleration....

I guess I don't understand what you are saying about going from 1st to 2nd.....My car is the same and has plenty of pick-up through 3rd gear. Even 5th gear has decent pick-up once you are going about 60mph.

Without some mods, I really don't know what you can do. Please try and explain the 1st to 2nd comment and we might be able to help you better.

well, if I don't go up to 4000 rpm in 1st gear, accelaration in 2nd gear is very slow. In other gears it sees to be not as bad as going from 1st to 2nd.

But overall, I'd like to add some power at lower rpm than 4000.

Thanks

shit... just notice I should have wrote add and not had....

English is not my 1st language....

u gotta let the engine rev high to accelerate in any car . 3500 - 4000rpm is for normal driving. let your tach hit about 6500 before each gear shift and youll notice a big difference in acceleration. for more low end power get a short ram intake and exhaust. you gotta let that 2.4 breath.

where can I found more info about these :" short ram intake and exhaust"

I'm a computer guy... far from a car guy (IMG:style_emoticons/default/smile.gif)

a short ram intake replaces your stock air box. its supposed to let your engine suck more air in. most people on here have cold air intakes but they are only good for mid to high range power. as far as exhaust, the stock exhaust restricts flow. Therefore is you replace it with an aftermarket exhaust it will flow more freely. you can find more info on these mods in older post on this forum.

I agree with others here. Get a short ram intake, get an exhaust, put the pedal to the floor and redline it, that will get you better acceleration. Remember this a 4 cylinder, these engines get their power in the high rpm range. And also the mivec doesn't kick in until sometime after 3000 rpm (not sure exactly what rpm). Going from 1st gear to second on my 2.4l manual at 6000 rpm I spin the tires everytime. Use the higher rpm range, shifting at 3k rpm isn't going to cut it, it will however get you better gas mileage.

ok...

I'd love to get more power without downshifting while accelerating.....

Next car will have a turbo for sure.

MIVEC, I believe, kicks in at around 4.5K rpm..

Regards.

sorry for my ignorance, but what does mivec do?

What I noticed is that torque is really better at 4500 rpm....

Anyone compared the acceleration of the 2.4l vs the mazda3 2.5l ?

MIVEC = Mitsubishi Innovative Valve timing Electronic Control system
Someone may be able to explain it better, but in simple terms, it's code written into the ecu that allows the extending of the injection valve opening time and expanding the valve lift range which increases intake air mass and creates more power.

mazda vs lancer:

Mazda
0 to 60 mph in 8.1 seconds
1/4 mile in 16.0 seconds at 86.3 mph
167 hp, 168 ft/lbs torque

Lancer 2.4L manual:
0 to 60 mph in 7.7 (some reviews show 7.2, others show 7.8)
1/4 mile in 15.8 secs at 88.7
168 hp, 167 ft/lbs torque

Thanks.

Strange, i read a review of 3 cars in a Montreal Newspaper (Lancer vs Mazda3 vs Impreza) and they said that the Mazda had better acceleration.

I tried both the Mazda 2.5l and the Lancer (duh, I own one) and it was hard to say which one had better acceleration because I didn't try them directly one after the other. It was a few days apart.

here are the scores (in french, ask if you need some translation)

you still have to down shift with a turbo

I know... but I'll have more fun too (IMG:style_emoticons/default/smile.gif)

Spelling errors in titles????


Just ask....I'll fix (IMG:style_emoticons/default/thumbsup.gif)

cool thanks.... it was an ugly mistake.... I was ashame of it (IMG:style_emoticons/default/smile.gif)

I got the figures I posted for the lancer and the mazda from edmunds.
Car and driver ranked the 2009 Lancer GTS manual as the fastest car under 20,000. Not sure what the 3 base price starts at, but for under 20k, lancer wins.

The valves are controlled by hydraulic pressure. The T-lever will contact the high lift cam when the engine RPM is above a certain point, causing that cam to manage the valves from that point on. As well, ignition timing is controlled by ECU.
It's all one big happy family that becomes unnoticeable in 3rd gear.

what does turbo have to do with this? If you slap a turbo on the same 4cyl engine, you still would need to rev your to same RPM level. The only different between turbo and non turbo on same specific engine.. is that turbo engine will get you to that RPM level faster than non turbo. So for comparison sake, lets say you need to get to 5500 rpm in our lancer to really get it going between 1st and 2nd gear. On a non turbo car it will take you 2 senconds to get to 5500, on a turbo car it might take you 1.2seconds (this is all for argument sake dont take these numbers literally). Besides, dont forget, your turbo doesnt kick in right away either. Most 4cyl turbos kick in at around 3000-4000 rpm. The bigger turbo you put on your car, the higher RPM needed to spool the turbo and see the effect. The only true way to get low end torque boost would be a supercharger which provides forced air throughtough your rpm band 0-6500 because its belt driven and not exhaust driven. hope this made sense and help you understand it better.

P.S. the bigger the engine the better low end torque. v10 engine has a lot better low end torque than v8 for example, but has lower upper torque... In other words, racing v10 engine you get mose of your HP at (again for argument sakes) 1500-3500 rpm then start losing it, where as with V8 you get it from 2000-4000rpm, with v 6 you get 2500-45000and with 4cyl 3000-5500
