You may have been going faster than you thought.

I don't know the height of your tires, but here's a calculator. Your rearend ratio should be 4.10.

I'm not sure what tires you have on the rear, but you could look up your tire on line or just measure. I'm not sure if the tire grows in height around 200 mph, but I'd imagine you could add a fraction of an inch.

24.7 inches tall 202 mph
25 inches tall 204 mph
26 inches tall 213 mph


Careful you're just about at the blow off the road speed. Though the FD has incredible coefficient of drag and minimal frontal surface area it's down force may be a bit challenged..

Sorry to be like a dad, but we care.

 

That is good to hear. These cars are fast & as Mr. TT posted, built like tin cans.

Have a good weekend

It was an FC that lifted off at 215mph. The speed record for an fd is 23X mph or something like that. Nifty **** thats for sure.

 

rear tires are 245 45 16 fronts are 225 50 16 dont know how big that would be

 

they would be 25 inches

 

it was actually an FD that got airborne at 215

 

^^ Correct it was RacingBeat's FD, airborne at 215Mph.

 

Nice!!!!

how much of a difference is there once you go over 170???? I'm gonna guess its pretty much the same...things just go by a bit quicker - lol

congrats on the huge set of cojones!!!!!

 

yeah, I'd say he has some ***** of steel going 204mph on a public road.....that would scare the living **** out of me....=O)

 

it wasent that bad well at least i dident think it was car felt preatty snug to the ground

 

yeah thats gnarly

I love topping cars out, then later I always scare the **** out of myself with hypothetical situations and what if's

 

Im not trying to act like a parent towards you cause you're an adult and you make your own decisions but its not only so much about your car "feeling" stable, you can have a tire blowout, lose control due a small imperfection in the road, or other things that can lead to a fatal crash.

I remember one time my friend was driving his 01 chevy extreme and those things are slow, he was trying to top it and it would only go 95mph. I guess that was the factory limit and he just tried to hit 100 and the truck shut off completely.

And you know when a car is off and you turn the wheel a bit, the steering wheel locks? Well that happened to him at freaking 95mph. The damn steering wheel locked on him and i dont know how he stopped safely. I guess it was an empty highway cause if there were some cars around, he would def crash into them.

Just be careful man.

 

steering wheel will not lock if the key is still in the on position....in which case if it just "turned off" It would still be in the on position.

....Interesting.

 

I know

Tell chevy to fix that problem.

 

crazy

 

Yeah it was, but if you watch the video, its on the salt flats, and the car lost traction due to the poor surface, then started to spin. Once it spun sideways and almost backwards the rear end has high lift in the wrong direction and flipped it onto the roof. So I dont think the FD is unstable at high speed, but many things could kill you going that damn fast!

 

 

lost traction was due to too much downforce on the nose...if it was from poor surface, then what about all the other cars that run on the flats? if you watch the vid in slow mo, you can see the nose dig.

 

WERD! If you watch the fender on the right front side youll see it start to go down over the top of the tire.

 

i drove my fd to 160 and the car felt very stable. im sure some R compound tires, a rear diffuser, a wing, and some front canards and you should be ok. i'm not saying do it but it would decrease the risk. i'm assumeing he had the GTC front when he did this which should by mazda design added down force to the front.

 

yes i had that ans mazda speed sides and c west rear

 

i did 160 n/p only thing that scared me was if i got caught.... yea u'll probably die if u crash but no point of driving a 'fast car' slow.
Nice vid, and even sexier FD

 

I didn't realize how much more gear the FD has. We had my buddy's CYM TII to a calculated 173. 9000rpm in 5th gear, speedo already wrapped around....lots o fun!
He had a ported motor, 3"dp and exhaust, hks bov, stock tmic, fpr, external wastegate, and a full suspension

 

hmmmmm....wouldn't it take about 300 rwhp in a TII to make that speed?

 

you got some ***** man.
