Help me i beat my brother's bmw 318i only barely. my brother bmw is a 4 door saloon standard 1.8 litre injection, its a heavy car. we both raced each other thursday nite and i only barely beat him :oops: i should of pissed all over him we were neck and neck 1st, 2nd, 3rd, well i taught i would trash him. i think i'm not gettin the best out of my swift. if you click onto my garage and see my mods, i should be a least expecting 120BHP from my swift, it seemed nearly faster when i bought it totally standard a year ago :cry: . what should i do? and whats happenin :furious: :WTF: here it is Image

with the mods u have I ran a 15.7, At that point its all driver. Having said that. When my car was N/A i walked all over those 318 piggies. you have to work on your shifting. maybe your shifting to high or too low. Try shifting at around 7300rpms if u have stock cams. The stock cams make power up to around 6800rpms. You whine them up to 7300 so when you shift it won't drop to low in the power band.

What kind of octane can you get your hands on? try advancing your distributor a couple hair lines. makes a huge difference

also try cleaning your maf too the car runs much stronger with everything is tip top.


good luck on that.

sorry what do you mean by advancing your distributor a couple of hair lines :?: and cleaning your maf :?:

By rotating your distributor towards the firewall a bit you are advancing your timing. If you look on top of the distributor you see 2 markings 1 will be a arrow on the dizzy. loosen the distributor and move the arrow a couple mm towards the firewall. If you notice pinging its because you moved it too much. You can move it until you hear the motor ping and then back it off till it stops. Just make sure to run high octane fuel.


And cleaning the maf, you need to take the sensor(black piece with the connector) out of the maf housing (2 philip screws). When you remove the sensor you will see 2 hotwires with tiny resistors (be very gentle and careful not to damage them) , get some electrical contact cleaner and spray them till they are shiny or until they are not black anymore. If the hotwires are still dirty you can use a cotton swab (a q-tip?), spray the swab with the cleaner and very gentle wipe clean. Give it a few minutes for the cleaner to evaporate and reinstall you done.

You will notice the car runs much better overall.

Also try using a short ram and cone filter intake setup.

Bro your mods aren't going to yield that kind of power increase.

For starters having a wide-open (free-flowing) exhaust and a huge throttle body are probably killing your torque. As for a short-ram intake most of those end up breathing in warm engine bay air... Not exactly the best thing for making power.

You should have that beemer no problems, even with a stock car :shock:

My cars making 113.3bhp just with filter and a decatted exhaust system.. 2 dyno printouts too, just because I thought the first one was a bit too much.

120 shouldn't be toooo far off the mark for his mods?

Exactly.

Be carefull not to advance the timing too much. You should have a timing gun to do it.

When was your car last serviced? A dirty fuel filter or injectors can be very mean to the cars performance. How is your oil? is it clean? and the oil filter? The spark plugs?

I usually race without the air filter.

I get awesome accelaration without the filter, but when driving normally flat spots are all over the place, especially around 2k :(

13% - 13 hp - from a filter and a free flow exhaust? Sounds like that dyno is a little optimistic to me - did you do a before & after run or just two after?

They're two different dyno centres.

One was 113.3 one was 112.8

I like to think the first one was more accurate :lol:

Not sure what else the cars had done mind, because it was already a bit played with when I got it, but pretty sure that its not cammed or anything like that.

well my exhaust system has a center box and a exhaust doh. but ya i think my filter mite be taking in a lot of hot air, was thinking of shielding my air filter with aliminuim from the engine

ya just changed the oil and oil filter and the spark plug, maybe i mite change the injectors.

If it really is BHP then lets remember thats at the fly and not at the wheels so 120BHP is certainly more realistic than 120WHP.

Dont go near the injectors ya noobie.

What would ya change them for....???

Ya could get them cleaned but I doubt thats your problem.

Those BMW 318's may be big and heavy but they still haul ass for a german tank!

I think your exhaust is letting ya down a bit...any leaks?

ya true i'm just confused, i don't think my exhaust is leaking but i'll check, it's a second hand exhaust system from dublin could be wear and tear inside, is your car de-cated? because i'm worried after hearin 'TheINCride's comment :cry:

Did you replace the fuel filter? is the timing on spot?

Don't change your injectors. If you never had them cleaned, you should do it.

run a short ram and a 1 3/4"-2" exhaust. These are tried tested and true mods for our cars, The short ram improved my 1/4 time compared to the stock intake, your throtle response will also improve. Also the shortram is better then a full out cold air intake ( filter in the fender) again tested at the track. I find anything other then the shortram slows the air flow a bit. I know many ppl will have different opinions on the short ram setup with the warm air but... with what it frees up on air flow(with a cone filter)i think it still an awsome mod, there will be many that agree. At the end of the day just try it out and see what works best for you. Go to the track try a few things and record what u did and what made u faster.



the track.... or a G-TECH

Hey Leegti try this. I used to work with a guy who was a hardcore mustang guy. Monthly dyno runs and a massive ford racing tab. Anyways he told me one day that they ice packed the area around his air filter, or his buddies watever. Apparently they measured the charge or sumthing from the colder air and it yields a better perfomring vehicle. But everyone seems to see that there vehicle performs better in colder weather. I know someone will be able to better explain the whole cold air thing but basically cold air is better. Short ram is good but i personally think cold air is better. Now im not saying race him with an ice pack but try sticking your filter somewhere else. Wheel well is okay but gets dirty and is a pain if its raining. Before i bought my new car i was thinking of cramming the filter infront of the header. You'd have to remove the heatsheild and reduce the pipe to squeeze between the block and the body but it sure would look sharp and give you tons of cold air. Or you could keep the short ram and go t3 style with a hood scoop.
