nevermind, I just read you were going to drop it.

 

well the whole ordeal is off now i think the 85 gsl i was gonna get is a total pos, its a shame someone would let their car get like that!

i was gonna use..

TH200-4r trans with b&m shifter

 

I thought that was my point ?!? Just because you can recover some semblance of stock weight distribution, doesn't make the car suddenly handle like stock.... Like manntis said, its not the added weight, it where it's been added that causes handling woes. The location will tend to over accentuate roll and yaw, especially up front. This lowers lateral grip, and ultimately make the car feel slow, and unresponsive, and causes both poor brake bias, and again loss of braking traction. The weight slows steering reaction due to the greater polar moment of rotation. The yaw will shift more weight to the rear during acceleration, which given the fixed anti-squat ratio of the cars rear suspension, actually could decrease the forward grip. And the list continues. "Simplfy and Lighten", not complicate and laden... that's the key to overall performance.

 

The way you describe it, I'd sooner put a 3 ft. high, tri-element carbon fiber wing on the rex before I'd urp a V8 in it....

 

your arguments are completely irrelevant, have to swapped a v8 into a 7? how do you come up with what exactly will happen, do you know the specific amount of weight and exactly where it will be and how the car will react in the real world, not just with your "theories", your talking like some genius physicist, you should THINK like one.. lol

 

ok whatever everyones feelings are about V8's in RX-7's
if its there car then they can do what they want, maybe they dont care as much about handling as the do about instant torque and high hp for not much $$$ it doesnt matter what you think its not your car

 

Dude, chill..... I don't know everything. But there are few things I do know, from there its easy to calculate the changes that would happen in terms of physical properties. Not everything has to be gained through direct expirementation to be sufficiently proven.

I've been doing a alot of reading/research on the handling dynamics. I live at the Unversity, and when I get bored/frustrated of my masters thesis, I grab a book about cars. I suprised at how complicated the whole thing is, and how small seemingly insigificant changes in weight location change the performance drastically. It doens't take a genius to figure out how much the center of gravity would change, or estimate the rotational moment either....

I mean you no harm, or ill will, but I think people on this forum should be informed when it comes to drastic decisions.

 

Quite right. And on that note, I'm gonna close the thread. Not because it's getting out of hand (you all have done pretty well with staying on topic and not flamming -- kudos), but because it's been pretty well beaten to death, and it's pretty clear nobody's mind is going to change on this issue. With that said, see the quote above
