I was arguing about swapping an LSx motor being swapped into an FD and he throws out this:



LS1 RX7

LF 684lbs RF 695lbs (50.5% front)

LR 708lbs RR 645lbs (49.5% rear)

Total 2732lbs (55 lbs more over the rear of the car)



RX7 (R1 model)

LF 719lbs RF 718lbs (52.9% front)

LR 660lbs RR 618lbs (47.1% rear)

Total 2715lbs



I thought it had perfect 50/50. Also what kinda power are you guys running with pump gas and are driving it daily? Thanks.

 

The stock RX-7 had near perfect 50/50. Keyword is near. Also, for the LS1 guys, it's best just to let them be and not a argue with them. The only argument they'll listen to is if you top them.

 

triangle, i don't know who you were arguing with, but those are my numbers. i posted the video of me corner weighing my car, alongside my friends stock r1. so the #'s are real. but keep in mind its not an apples to apples comparison, because my car has some alterations that skew the #'s in my favor:

-i have no ABS

-i have no PS

-i have no AC

-my battery was mounted in passenger side bin



so those factors help my front/rear distribution.

if you'd like to see the vid, right click and "save as" on this link:

if you want to know more facts, i think i posted them in this forum; just search my username.

 

What's wrong with those numbers? Looks correct to me.

 

Thanks for the info. I wasn't doubting the weight on your car but I thought the rotary-powered one would have been closer to 50/50 than it did. Oh wells. The guy I was arguing with didn't post the video until after I made this thread.

 

no prob man whats the link of that discussion?

 

no one ever accounts for fuel when they calculate the weight ratio either... 20 gallons of gas behind the rear axle makes a HUGE difference also.

 

very true, considering a gallon of any liquid is 8 pounds right??

 

liquids vary in density, so no, a gallon of water does weigh 8lbs, but a gallon of gas does not

 

we both filled up prior to the event to avoid any fuel slosh issues. but i have reduced capacity tank (15 gallons) and he has stock tank (about 20 gallons?).
