Why is Wrx faster then a Gsx?

[h82lose]

I was just thinking about this today. Why can a wrx run a 1/4 mile in 14.3 while a mitsu gsx with same all wheel drive and turbo run only at 14.5 or 14.6? Isn't the wrx heavier? I believe the wrx has 217 hp and the gsx has 210.

No, WRX sedan-wise is lighter.

I looked in the GSX curb weight which was 3157 lbs, assuming a manual tranny. The WRX sedan curb weigt is 3085 lbs, which is also a MT. However, its wagon counterpart is 3165 lbs.

Wow thats suprising because the wrx just looks heavy while the eclipse doesn't. Now are there any reason why the wrx is faster then the gsx. bigger turbo better cooling what?

The WRX also puts a bigger portion of its power to the ground then the Mitsu. The Mitsu dynos stock around 175, and the WRX dynos about 190.

Those arent exact numbers, but its another general reason.

[SuBaRuRuLeS]

WRX has 217 of torque, and 227 of horses!!:smoker2:

Im talking about the dyno, we all know that 227 is at the crank, not on the ground.

Neither of those cars run those times. A GSX tested stock is clicking off low 15.1's-15.2's, what does a Subie test at? 14.9-15.0? I've ran many a Subie's & only found one that keep up on a decent launch.

i have seen numerous WRX's running 14.1's-14.3's or lower bone stock and the GSX's running 14.7's-15.2's anyways you are comparing apples and oranges.....GSX is a different class car

[mugenrsx]

wrx has more power and is lighter. end of story. and turbo wagon you should try pulling some thing else out of your ass, besides wrong numbers!! wrx with good driver runs 14.2 ALL DAY!! its been tested over and over again and agian by most magazines.... GSX suck...

You have to remember the WRX is a new car than the GSX, and so benifits from a more advanced engine design. The 4g63 in the Eclipse is not nearly as advanced as the newer versions in the latest EVO's which are even faster than the WRX.

The WRX also has notorisouly short gear ratios.
The 22b for example is limited by gear ratios to a top speed of only 180kph. (about 110-120mph)
I have no idea how Mitis set the GSX up for the US, but I assume it has tallish ratios to enable to cruise long distances.
Its possible the US spec WRX is set up defferntly to the rest of the world, but unlikely, and at the most I suspect it would only have a taller 5th gear.

SO basicly the WRX will have a more flexiable engine with more mid range Torque, and a G/box with a shorter set of ratios, all of which allow it to be that little bit faster down the 1/4.

better power curve? better gearing? just guesses, but those are common reasons why numbers dont ususally tell the whole story.

I'd say the rally gearing is more then half of it. The Gsx has much much taller gears.

Any one know the A/R on the Gsx turbo?

[mugenrsx]

The wrx tops out at 140 ish as tested. Its not the gearing its the 17HP and lighter body. Plus i can bet that the AWD drive system is better. The wrx has a good stock differential in rear. I mean think about it, weight is everything, the WRX being lighter is like having 20 more horsepower. I'm sure a GSX with 37 more horsepower would do the 1/4 in 14.2. if not than thats pretty sad.

[mugenrsx]

also the GSX could have a more restrictive motor than the wrx. could have a crappy intake system, worse exhaust, heavier wheels, bad suspention making the body mtion acward off the line.... Its like that other guy said the wrx is more advanced the GSX is old school.

[LjasonL]

i dunno man, my car has freakin short gears. im redlining 4th at 100mph. plus ive got a 3.9 final drive instead of the wrx's 4.11. its just got really close 1st-4th, then a long spaced out 5th for overdrive.
