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. https://www.nopistons.com/forums/pub...1047683473.gif

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 https://www.nopistons.com/forums/pub...IR#>/smile.png 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?).
