I'm shooting for 240 whp and 160pounds of torque with my b series project. I was wondering the weight advantage on an EG and EK hatch. Does any know the weight of a full interior eg hatch without driver and the weight of a full interior ek hatch without driver? Also how drastic will the time slips be between the two in the quarter mile considering both with same mods, same driver, etc.

 

I think there is about 150lbs difference fully loaded.

 

how about gutted without ac, power steering, ect. Is there much of a difference? also with 150 pounds difference how does that affect the quarter mile time?

 

i would say that 100 lbs is good for a tenth.... but sometimes weight in the right areas will do wonders as well

Yes they say 100 lbs equals a tenth.

Depending on where the weight is is a big factor. Lets take the sunroof for example. Say you put a plug in it that saves 35 pounds. That weight is off the highest point in your car. Now take say your A/C off and thats 35 lbs. That is about mid/low car. Take a 10lb weight and run with it at waist level, very easy. Take that same weight and attach it to a 3 ft pole and try to run, a lot harder to get going. Hope that explained it, makes sense to me...

It all has to do with center of gravity

but does a lighter chassis always equal a faster time?

 

YES ... but again if you add weight to a light chassis in the right spots it could be faster.

 

amazing. Does anyone know the weight difference in a GUTTED eg and GUTTED ek. By gutted i mean no ac,power steering, rear seats panels all the way to the back hatch.

a gutted eg with no driver i would say is 1900

 

what you want is as least rear weight as possible and really stiff rear springs. when you launch and when you shift, weight is naturally going to tranfer to the back which sucks for front drive, cause drive wheels are up front. the springs in the back will stop some of that weight transfer. you can figure every 100 lbs equals a tenth added to your 1/4. if your so worried about weight get a crx

 

weel i was deciding between a ek and eg. Just wondering what the weight difference is gutted.

 

with all thing remaining even it would stand to reason that they would still be approximately 150lb different. I dotn know if an ek seat weighs more than an eg seat, etc .

 

What sucks is the EK's just look so much better.

 

150 pounds is not bad at all if you use the theory off adding 1 tenth of a second for every 100 pounds. unless you hit 13.14 in an ek

 

My track experience has shown that in out light cars, 100 pounds can mean 2 tenths. Its happened to me many times. This year im racing my turbo b16 del sol, so ill really be hurting.

 

i found 100lbs=2/10ths in my car. but then eventually you get into the land of diminishing returns and then 100lbs=1/10th. my biggest thing with weight off the car was driveline parts tended to be more reliable.

 

in a EG hatch with 150whp a 120lb addition added 2 tenths (.2x) to the ET
3 times in a row.
so the less power you have the more it shows up
