Why cant we just be one big happy japanese car owning family? I own a Supra, Im not arrogant, im not an *******, and I dont care at all if an rx7 is better then a supra or not. IMHO I like supras better, Im more of a power lover, and I gotta say 230 hp and 246 lbs torqe is pretty dam good .

 

Personally i couldn't give two donkey nuts where your car comes from.....japan, germany, france, england, detroit, or Ohio. If it's quick then it's fine by me

What amazes me here is the amount of Ignorance......FROM both parties. WEIGHT is NEVER good, if you're trying to go fast. NEVER. talk to anyone that does time trials. IF you don't know what time trials are....then just keep it to yourself.

OH yeah and with 207RWHP, and 199lbs/FT of torque i ran high 13's. So i don't know what kind of vegetables some of you are smoking.

 

i'm smoking carrots.

 

Hey guys Forum wars do nobody any good. RX-7's are beasts, Supras are beasts. Different cars are what makes owning them fun.

There are many people on the Supra forum who really know their $hit. I'm sure the same goes here. The one thing I would say about the Supra forum is stay away from the kills threads. Most of those posts are by wanabe 15 year olds who don't even own Supras or anything else.

I'm a 3rd gen (mkIII) Supra owner myself, and I think that crowd has the nicest ppl. The mkIV crowd tends to be a lot more arrogant (hell many of them look down on us mkIII guys). Especially since that damn Fast & Furious BS.

Anyhow we aren't all trolls and as far as I am concerned you guys can come post in the mkIII section anytime.

I ran across this thread here.

Anyhow, that's just my .02, and what do I know. I'm just a novice anyways. On the otherhand I can appreciate any car that performs.

ok wtf, weight doesnt do anyone good? Are u f'n stupid? ok, im not gonna bother talking anymore in this thread cuz u obviously dont know ur ****...

 

I think mommy called him to dinner.......

 

Gotta comment on this one.... so have you ever taken BASIC physics? maybe...
so do tell.. where does mass factor into top speed of a car?
(actually, if anything, more mass = increased normal force * coefficient of friction = increased force of friction = LOWER top speed)


And u know what? thats what it's all about... (I love my car, u love your car, we're both happy... the end)

 

actually i havent taken basic physics...

but i have learned some stuff from calculus and fixing/modifying cars...

u are right, i was thinking of it a downhill situation for the weight, but everything else i said, is tru...

Autocrash, being from a physics background, (i assume) u must admit that weight does have its advantage in high speed turning or banking (ie. road coarses)...

Who here has seen that rx-7 doing a top speed run and then just start flipping? That s because of poor aerodynamics, and not enuf weight to keep the car on the ground... the same applies to a lesser degree in real life...

Yup... I am from a physics background. However, my knowledge of vehicle dynamics is not as evolved as my knowledge of physics...

As far as heavy cars turning goes, I would assume that the extra weight would contribute to more stability through the turn. However, the increased weight would also mean that your tires are "holding" a larger force... not good for tire life...

I also agree that aerodynamics will make a car flip. Not neccisarily poor aerodynamics though. Has anyone seen LeMans Prototypes flip? ('cause I have) and those cars have got some amazing aero work done to them... and yes weight would decrease body lift at high speeds, so to would proper aero body work.... (the good ****, not the ricer **** )

(I think what I'm trying to say is that in most cases there is more than one way around a problem... but I can't really tell 'cause I'm still drunk and hungover from last night )

But hey... I love the look of supras... I'd like to own one at some point.... (80's cars rock! )

Hopefully that made some sense.... I'm going for pizza now....

 

cool, it did make sense.... enjoy ur pizza, BTW where in ontario u at?

Also those "ricer" gt wings, actually do help out our rwd cars on downforce, because when ur going fast, you want to get as much drive force on the drive wheels as possible, esp when going around turns... but in the 1/4 itll prolly slow u down...

 

Um, ok the 3rd gen RX-7 that flipped was doing 242MPH at the salt flat without even the stock spoilers. It didn't have enough down force.. it needed a spoiler..


The reason it did flip was because of aerodynamics NOT weight.


You seem to like to make up things. You obviously do not know much about RX-7s.

Study up more, because the supra's main competition is the RX-7. They are both great cars. The RX-7 is built for racing, the supra for touring.

If you guys are going to argue a point, at least get your facts right. The 13B's stated 1308cc capacity comes from the standard definition of engine capacity, being the difference in cylinder/chamber volume between TDC and BDC multiplied by the number of cylinders/rotors. But a single rotor sucks in that volume of air once per rev, whereas a single piston only does that once every two revs. So in theory a 1308cc rotary should inhale the same amount of air as a 2616cc piston engine, and hence make similar power. But in practice this doesn't quite happen, which is why a capacity factor of 1.8 is usually used in racing, giving a capacity of 2354cc (2.4L).

are you saying my smart a$$ comment was out of line? I thought is was a good one.....

 

umm.. no, weight does not have an advantage in high speed turning or banking.

Well, see the problem with that is that tires don't behave linearly.. when you double the weight on the tire, the tire gives you less than double the traction..

as for added weight giving you more stability- yeah.. it wants to keep going in whatever direction it was going, i.e. a straight line and NOT following the curvature of the course. It requires more work from the tires on corner turn-in, and once it starts to spin, it's tougher to stop it.

I'm not saying the Supra is a bad car, I like it just fine.. I'm just saying weight, in and of itself, is never your friend for road racing.. The people that legitimately race supras in sanctioned road racing competition aren't thinking to themselves, "Man, this car could really benefit from some more weight!"

 

In relation to the weight issue. Okay too much weight is bad but to little weight is also a bad thing. You just have to find the median in between. The Supra is a bigger car and obviously wants to shave weight off. The 7 just has a better weight distribution for its style.
- Steiner

 

please define "to [sic] little weight" or cite an example of it.. I imagine it's probably a weight balance issue, rather than a total weight issue.

(unless we are talking about traffic accidents or something not road-racing related..)

 

O'k maybe it's time to end this most informative of threads. For those that feel comfortable making statments like "all _______ are arrogant etc, I believe the term is bigot. All the forums are populated with people of varying IQ's,knowledge, and temperments. Unfortunately, many of the people on the low end of this scale tend to be the most vocal. All the car forums share a common interest, so why not build on that instead of slamming the ignorant few. It's not hard to find the misinformed and biligerant, and it's even easier to call them out. I wonder if thethe initial starters of this thread could have added something meaningful to one of the tech forums, or are they just like the guys that they are calling out? Anyway, as has been pointed out before, forum wars are not productive, and they certainly don't make our cars faster. One of the nicest meets I've been to lately was in SF Cali, and incuded all enthusiasts. we had over a hundred cars, ZO6 to Miata and everything in between. Everyone attending had a great time and know one walked up to me and told me I was arrogant because of the car I drove.

@ that thread

 

friction = normal force * coefficient of friction on surface.

Im glad i took physics..i understand what people are saying

 

hehe... I'm glad I took physics... 'cause then I can say things that make me look smart


MechE00:

As I said earlier, I don't know much about vehicle dynamics.... I'm not there yet... lol..

btw, does MechE00 stand for Mech. Engineer? ('cause thats what program I'm in right now)

SupraAng: well... I used to be from Peterborough, Now I'm living in Ottawa...
(damn there are a lot of Porsches in Ottawa )

 

Did one of those guys say 400lbs doesnt make a difference? Isnt it a general rule 100lbs = .1s in the quarter?

 

Yes that is correct. you shave off ~100lbs, then you save yourself ~.1sec in the 1/4 mile

looks like the 7 won, i dont see any sign of a video though
