start speed

[yuhou411]

ok so i have a 325i.. it has intake, dinan chip, suspension strut bar and ect... im just wondering if you guys have tips on what to get to speed up my start up speed. im not that intrested in increases top speed but im not really satisfied with the acceleration. i know that a turbo and or supercharger are main parts to get but those arnt in my price range right now. so any other ideas would be great

[bimmerguy82]

is it auto or manual? do you have lsd? if it's auto then you're kinda screwed for acceleration unless you change the torque converter or gears.

[yuhou411]

its a manual, and im not sure what an lsd is.

[SHAHAB323IS]

lsd = limited slip differential

buy one

zionsville autosport sells used ones

just look under m3's and differentials

weight reduction, how heavy are your wheels? check the search we have thread about this.

lose unsprung weight... ltw flywheel and ltw rims could be a good start.

Differential change gives a better start off, however you'll loose top end speed and fuel economy. Even smaller tires and good shocks help acceleration.

Other things are a freer flowing intake, a cooler intake charge, hotter spark, and freer flowing exhaust.

And my personal favorite late ford 5.0L early 4.6L fuel injectors that offer better idle, faster starts, and over all performance.

Starmavin, Just for my curiosity, would having those 4.6l ford mustang injectors work on a 92 325i that only has an intake and chip + auto?

[yuhou411]

is there a way for me to find out if i already ahve a lsd or not? also wut is taht fuel injector peice? and around how much will it cost?

[yuhou411]

o and also what kind of lsd is a good choice to get? and why are ford fuel injectors good for my car?

[Starmavin]

Yes, they will work. They are physically identical, they have 4 pintle (disc) injector nozzles that offer better fuel atomization, although they flow about the same (yellow top 19lb/hr) On boosted cars the higher flowing ford 24lb/hr racing injectors (blue top) are needed.

if you want something basic you can get free flow exhaust, not to expensive and you gain a little bit of tourque (not alot though) but man it sounds nice
