Folks... I searched in our 3rd gen forum, and the time slips and dyno section, but no luck. I was just wondering if you all could inform me (us) what your best 0-60mph times are, especially those who have it heavily modded. How much did you improve over stock? I've seen anywhere from 4.9-5.3 for stock times. I've never really timed mine, but would probably want to go to a track sometime just to see...

 

Trying to time it yourself is almost surely a waste of time. You need a pretty good timing/speed setup to do it properly. It's better to compare 60', 1/8mi, and 1/4mi times, IMO, since those are accurate measurements that ordinary folks can check.

There is a calculator for figureing it out somwhere on the web. You pu in your 1/4 and trap speed and 60 foot time and it calculates it out, roughly.

 

true... it probably is just one of "those numbers" that manufacturers and magazines like throwing out to give their vehicles the wow factor. And like the above mentioned, there probably is a calculation for it. But still, anyone have any numbers? especially for a street driven FD?

 

I just have a downpipe and Apexi intakes. From what i can measure with my stopwatch I am getting 0-60 around 6 seconds. I have to say I'm a little dissapointed since it only has 1200 miles on the reman. I don't have a boost gauge yet so I can't really tell what's going on with the turbos. It's still good fun though.

 

Sell the stopwatch and use it to buy a boost gauge :o)

The reason why stopwatch timing isn't even close is simple: the common method of measuring 0-60 involves starting the timer the moment the car begins forward movement, unlike the tree at a drag race. It also stops timing the moment the car acheives 60mph. Both of these variables are hard to get correct with a hand timer, and if you want to have a chance of it, you need a helper to watch the speedo and do it. Even still, timing a 6 second event consistently is not possible - I've done enough hand timing of the 55m at track meets to confirm that you're lucky to consistently stay within .2s of the same time, and there you have very clear and instant reference points (smoke from gun, runner crossing the line). A sweeping speedo needle that's not directly in front of you is hard to read, as is judging the precise moment you start moving.

To do it the way the magazines do it, you need a radar gun pointed at the car and an integrated electronic timer.

As for the calculations, it only takes complete 0-60, 1/8mi, 1/4mi, and trap speeds for several cars to create a curve fit that will estimate the 0-60, given the other inputs. If I had the data on hand, I'd do it in Excel for you since it's an interesting exercise.

Yes. Boost gauge and AST are high priority. New Escort detector was slightly higher though. This is my high class stop watch. Timex. If I get really excited the horn beeps when I hit the buttons, but that's probably more than you wanted to know. At least I don't have to take my hand off the wheel!

 

LOL @ the stopwatch

at least get a gtech competition meter..its more accurate than a stopwatch thats for sure..or you can go to the track and get real times although you wont know your 0-60..you can only guess your 0-60 by 1/4 time..

 

Yea, that's on the list too. I swear this car is just a space in the garage in which to throw money.

 

I bought a Gtech accelerometer for 35 quid and suprisingly it seems very accurate.

Just plug it into the cigarette lighter and a suction cup holds it to the windscreen, so you can use it easy between vehicles.

It measures 0-60, standing 1/4, BHP, stopping distance, G force. ( I've never heard of timing 60ft runs before I saw it here, never seen it in UK).

Anyway, my R1 with induction and cat back (before I fitted mid pipe) gave me a best reading of 0-60 in 5.7 sec. 1/4 in 14.3 @ 100.
It should be alot lower now since I fitted a mid pipe last week but haven't tested it again yet. Certainly feels way quicker to drive.

Point to note is I found the launch made a big difference to the time. An average low RPM launch gave about 6.2sec 0-60, so to get down to 5.2 you need a damn good technique, sort of 5K rpm and a good clutch lol.

 

Wow... good info mate. I heard of those gadgets that can measure 0-60 times "quite" accurately. 6.2 seconds? That does sound about right though. I think folks who got times of 4.9 - 5.2 probably burnt the clutch off after a few runs

Let us know what numbers you get with your next bolt on...

 

this is what i got from http://www.albeedigital.com/supercou...0-60times.html

That's a big drop from '83 to '84 without a turbo involved.

 

I can hang with my co-workers 05' vette with a really good launch so I would say in the mid 4 sec range. That's with stock tire size and Goodyear F1's. He been drag racing for 20+ year and at the strip has run a 12.4. We've done it a few times and I lack his consistancy but with a good start we are door to door by the time I hit second. That with a fair amount of wheel spin if slip clutch he blow my doors off. The bitch is he doesn't have to shift until after 60.

 

corvettes rock wheather they are fast or not

you'll never be able to match the 60 foot of a vette in a rx-7 there's many many guys running 1.4 60 foot times on et streets all motor

 

My stock 94 fd will get to 100 km/h in around 6 seconds.
80-120 km/h in 3.9 seconds, no brake boosting.

Yes, that is interesting. I owned an 83 GS and the figure is correct, if you don't slip the clutch correctly. With a careful 2000 RPM drop, you can knock about .5 - .7 seconds off that time. I had an opportunity to drive an 84 GSL-SE and that number is pretty acurate as well. The difference, of course, is that the GS was carburated vs fuel injection for the GSL-SE. By the way, they were both tough little engines compared to the 13B we drive in our FDs.

 

GS is a 12A carbed, GSL-SE is a 13B fuel injected, thats why its was a lil faster.
