jsut wondering if the stock tranny gears are able to hit 200 mph? if not what would be a good gearing?

I'm pretty sure it has more to do with your rear end ( final drive ).

Manual FD's have a 4.10

A Auto has a 3.73 i think

So the Auto rear end would be better for top speed

But i dont see why a 4.10 cant hit 200 with enough power behind it.

4.10's might be pushing it a little. Do you plan on driving 200mph anytime soon?

rfreeman27 02-18-2005 07:05 AM

auto is 3.90



I think there is enough gear stock but good luck with that...



How fast have you been? 165-170 feels like you are in a time warp..

https://www.nopistons.com/forums/pub...withstupid.gif 200 MPH is insanely fast. Even at 156 (Fastest I've gone in the FD) things were coming up WAY faster than I expected. It felt like you saw a semi truck on the horizon and started braking when it's way out there, you might not hit it.. Point is - When you're going 100MPH faster than traffic you need to anticipate a whole lot more!

if you do the math, 200mph is something like 8500rpms. my buddy popped hs engine @188....

vosko 02-18-2005 12:07 PM

fastest i went in my old FD was 175 indicated......god that was dumb BUT FUN ! https://www.nopistons.com/forums/pub...#>/biggrin.png

what blew his engine? bad luck? or is there more stress on it at high speeds?

I think I read that the FD is geared for 201 mph.

GreyGT-C 02-18-2005 08:51 PM

had mine to about 175 indicated also. I need my ass kicked for that too. There is no reason the car needs to go that fast if not on a track or you're attempting to break the speed record for the FD class or something at Bonneville.



It's kinda scary at that speed. https://www.nopistons.com/forums/pub...DIR#>/wink.png If you are seriously gonna try to break 200 mph.... do some serious investment in some real aerodynamic work. (watch the racing beat video from about 1994-5)

GreyGT-C 02-18-2005 09:07 PM

wouldn't let me edit it again. but i think this should help you.

Talking about the video where the guy flips going 215? It looked like God himself had lifted that thing it was so easily tossed.

well for a long run like that the temps prolly got too high and it detonated. with the stock turbos, i'm not sure you can put enough cooling in the car to keep the oil water and intake air temps from getting too hot after a long run like that

Yeah, I'm not really sure that all the bolt on bodykit crap in the world will keep an FD planted at 200+ on the street when a side gust of wind comes outta nowhere and lifts the nose.. You only need a 1 degree change in pitch to make it soar.

You really need this car...

did you read the article? its a supercharged v12 making 700+ hp

CletusFD3S 02-19-2005 08:50 PM

so 200 seems a little high? ill do some reading, fastest ive gone in my fd was 135 and i thought i was doing 85.... serousily. But thanks for the feed back guys

CrassFC3S 02-19-2005 10:36 PM

have friends who raced at 180.... but 200 is pretty fast i guess its not reall that much faster than 180 but its still really fast haha... if i were you id invest in some nice ass safety equipment, a nicer gear set and rear end would make 200 pretty easy to attain just have to worry about cooling issues, at that point i dont know what **** you could buy to keep it cool enough to avoid it popping aside from race ****

Yeah. If you want to see an RX-7 fly, got o stupidvideos.com and watch the 215 mph video. Supposedly it's one of the Racing Beat cars going 215 mph.
