well i received a 1988 rx7 when i was 13, it was a project car (this was 2 years ago) last month my brother got a 2001 mustang, both cars are stock, my rx7 is 5 speed and the mustang is automatic which would win in a race?

The Mustang's are pretty slow especially an auto, I think you should take him. You have the weight advantage though I believe he has 190hp. They are better than the earlier v6 mustangs but not by much.

Lies! 2001 3.8L v6 puts out nigh unto 200 hp. In coupe trim the Mustang is probably around 3200 lbs 3200/190 = 16.8 lbs/hp - an NA rx7 s4 is around 145hp and 2800 lbs - 2800/145 = 19.3 lbs/hp. So, stock for stock, sorry to say, in a straight line the Mustang wins unless your brother outweighs you by 300 lbs or better. I've done this run on the street myself in a modified NA and the v6 later model Mustang still walked me. :P

You're probably thinking of the earlier Mustangs - 94 to 98 the 3.8L made ~140hp stock and STILL weighed 3200 lbs-ish. You'd clobber the bodystyle before your brother.

TII of any year would trounce 'im though. Other than that, get him to autocross with you and you'll kick his butt unless he's good and you're awful.

I pulled up the data to check, mustang is 3110 lbs/193hp = 16.1. The RX7 (assuming N/A) is 2750 lbs/146hp = 18.8, so ya that is accurate. I was thinking the mustangs were more around the 3300 range, but regardless with that kind of power it should still be a drivers race, and the fact that he has an auto will slow it down. I guess it kinda depends on the type of race.

Maybe, but that's kind of a big margin to come back from. I know! Before you start, smack your brother in the head, HARD with a basketball! That might put you over the edge.

I was running with 3" exhaust, and a cone filter - so realistically I was probably about 160hp and he still pulled on me. At 160 hp, that puts the Rx7 down into the 17.1 range, but it still wasn't enough and I'm pretty sure it was an auto that I raced. Admittedly, we only raced to about 10 over the speed limit from a redlight, but if it was a full quarter it would have only gotten worse - I wasn't exactly "making a comeback" if you know what I mean.

Don't sweat it though - you don't have to win to have fun as long the people you run are good sports about it. I'll run people in my little 132 hp MTX Neon all the time just for fun. It's good times as long as someone doesn't get all testosteroned up over it.

1/8 mile track
Stock '88 GXL(white) 5 speed Vs. 2003 3.9L 'stang (yellow) 5 speed

I ran a slightly faster time than him the entire night, mostly because of my launching, but his best was only .1 seconds slower than mine.

dump the clutch and slow down before he catches up, you won!

dude im sorry but if you guys arent seriously raping v6 mustangs in your n/a fc's something is wrong. . . . i guess all i can say is make sure you keep up on maintanance and keep it tuned. go play around im sure you will get your brother

MechE00

Go to an autocross... you'll have a chance to learn a little about how to really drive for one thing, and you won't have to worry about cops or accidents.

If you think a straight line is all you can handle, then find a drag strip so you can get some reliable numbers about what you and your car are doing, and again not have to worry about law enforcement problems or injuring people.

A n/a FC is hardly an ideal straight line car, anyway...

But you're 15, so you will only hear what you want to hear...

Be safe, have fun, learn as much as you can...

Is the mustang V6 or GT...I'm looking at the 0-60 and 1/4 database from google and a 99 Vert V6 runs a 16.5...Say the coupe runs a high 15, race him from a dig to 120+ or start from a roll and you should slightly pull on him considering with all the torque and no top end he'll pull most out of the whole (which'll be hard in an auto). I can't guarantee that because its all in your shifting but you might as well...both cars are slow as ***** anyway, and hes your damn brother lol

For future reference, if you want to find out which cars faster go to google and type in 0-60 and go to the first link

Just because a car has a higher power to weight ratio doesn't mean it will be faster in a 'real world' race. You folks are forgetting all about gearing and torque multiplication.

Says the guy with the Lexus in is avatar - how many hp do you think a v6 Mustang has? You do know the new one has 210 hp as a v6 right?

If you're not stomping a 94-98 v6 then you need to figure out where you're losing power. If you're "seriously raping" a 1999 and up v6 Mustang then either he wasn't racing, or he's done a JDM B16 swap for reliability. I'm not being hateful to RX7's, I'm just speaking the truth - your 20 year old 146hp != 7 year old 195hp.

Oh, and as for "gearing and torque multiplication" if he has 2.73 gears, then you might be alright.

According to those dragtimes, it's almost exactly like I said - the Convertible v6 is doing 16.5, and the s4 NA GXL is doing 16.5 - the coupe underweighs the convertible by around 300lbs because of the added framework and conversion equipment.

edit: Oh, and if you'll notice, the S5 convertible Rx7 was a whole second slower than the s4 hardtop - and that's with extra hp - I wonder if the coupe Mustang could be as much as a whole second faster in the quarter than the convertible?

That sounds a whole lot like what someone said before -

Oh wait, it was ME!

The RX7 was not made to go fast in a straight line... when will people realize that?

bigdaddyp

from my experience, I would say that a stock 88 rx7 5speed could take a stock 01 3.8 mustang. My neighbor has a 04 3.9L auto mustang and has ran high 10s in the 1/8th mile, so that should give you an idea. My brother ran my rx7 at the same track, got a 11.2, but he bogged really badly at the line, and didnt take it to the buzzer on the shifts, so I would say it would be close, but the rx7 should take him.

Then I sure wish the world ran on your experience instead of the physics and numbers that it actually does run on. Having driven both vehicles though, and owning an s4 - I'm going to go with my original statement, which is that the v6 Mustang is going to win, but not by a huge amount.

I'm thinking 'Shortly after people realize that Civics aren't made to go fast... period.'

My5ABaby

iTrader: (7)

Yeah.

Rx-7's can go fast in a straight line, but they weren't originally made to. That'd be a better way to put it.

To paraphrase someone's signature I saw - "Drag racing an RX7 is like taking a hooker fishing - it may be fun but that's not what they're for."

I think it was originally about a Lexus IS300 or something.

Well my s4 na isnt stock but I think mine is pretty quick in a straight line, id take out that mustang v6 no problem with my car but then again im ported full exhaust intake ,upgraded flywheel/clutch, 100 lbs weight reduction.

My car has no problem quickly getting to the redline in 4th gear if i wanted though, though ive actually only redlined 4th gear twice...it seems to pull well even in the redline, the highest i prolly took it in 4th was around 7300rpm, which translates to 122 mph with the current tires i have, 5th gear would keep on pulling to the 150 mark but ive never tried but Ive been told it will by several members on here with similar mods to mine.

Richter12x2

Sure, as long he's stock, and not running one of their $150 true dual kits, $100 shorty header kits, or $25 cold air intake kits. This is a Mustang, mods are waaaaaay cheap - but if you find one that's stock as the day it was born, you'll probably do fine.

Dude is a stupid piston v6 3.8 litre that only has 190hp, that is weak sorry to say and even with true dual intake and all that crap i think hed be lucky to make 190whp (220hp at flywheel) and even with that i think it would be pretty much an even race , sorry but i think mustangs are a joke.

Cars with even 3.0 that are luxury cars usually make 200+ hp...if u compare that 3.8 to the 3.5 in the nissan 350z, the 350z is smaller and makes 280 hp ... just something to think about.

My brother use to race mustang gts with his eclipse gsx awd turbo and would pull them in 5th gear with a full boat of people in his car (4 people), so these v6 mustangs arent **** at least not to me..to me a v6 in a mustang is like a 1 rotor in a rx7, its just less power than youre suppose to have.

If the thing is stock 190hp, and that makes about 161whp which is about the same as my 1.3 litre 1988 model streetported s4 na (pretty sad when his engine is 3x the size). So basically the mustang will run high 15's stock whereas the stock s4 na will run low to mid 16's stock but if youre fixed up like me you can expect to run mid 14s to low 15's depending on if its tune and how i drive.

The only thing that may make my times not as good is not having a lsd, which I think may not make a difference of more than .1 of a second or so, but im not even sure.

Even if the mustang has 200whp and me with only 160whp , my car still has a better power/weight ratio by .1 according to rx7.com.

Now however if this was a v8 mustang, my opinion would be completely different but v6 is not the model to get when you are buying an american sports car if you want something fast and I dont even like v8 mustangs either but they are an improvement over the v6.

even the v8 1998 mustang gt is only 225 hp stock with a 4.6 litre...which i still consider to be quite weak for the engine size and according to rx7.com acceleration calc would only run a 15.02 1/4 mile which isnt the greatest time considering my rx7 would be an even race with it if it was stock and even if it was fixed up a little i think my rx7 would still be a good race for it in the 1/4 mile if my car was tuned and had max hp assuming 170whp id run about 14.5 or so 1/4 mile and if the mustang had 225whp hed run 14.3 so it would still be really close.
