Does anyone know what a Iron Duke should run in the 1/4 mile and 0-60 time, with the Isuzu tranny. I was thinking it should run a 11 sec 0-60, but that might be with the 4.10 rear end.

For a second I thought you said 1/4 mile in 11 seconds, I was scared that you were crazy.

11 Seconds? Sounds, well, pretty right to me, a 4cyl guy should chime in real quick.

Im not too sure but I heard they run in the teens at least as for 1/4 mile time (18-19 sec???). I have one but have never taken it to a drag strip to test.

I've never taken mine to the strip but a sundial would be more appropriate for the 1/4 mile time.

A sundial huh?.....never thought about using that. Course, I don't see how I could with the Duke. Cuz, you know how fast that duke is.....I have timed a 0-60 mph run of around 19 seconds.

Befarrer has 1/4 mile time 18.6@70mph listed in the 1/4 mile thread. trans type not listed.
With stock auto, 84se, a good tail wind, running opposite the rotation of the earth, 1/8 tank of gas, passenger seat removed, int baffle removed and muffler removed, well, a dump truck pouring gravel on the return road beat me down the track. I still think he redlighted.

You can get a duke under 10sec in a 0-60 run if your good at slamin' through gears. The 4.10 trannie really helps.
Now if you have an auto, your kind of screwed.

I always wanted to get an 88 coupe, do a few little bolt on mods and run a 4.10 behind it. Would probably be a quick little 4 banger fiero!

I wonder what's wrong with my engine then. Cuz I just replaced it with one from Autozone I believe....What things might make a rebuilt engine not run as it should?

Let's give the Duke the respect it deserves. Mine has 133,000 on it and is clearly well worn. However, it'll easily leave your average ricer in the dust - and will pull away (slowly) from a 3 series BMW.

I suspect that the 1/4 mile time should be around 18 or 19 seconds; about the same as a V6 Toyota Camry.

Not bad at all for a worn-out 92 horse 4-cyl engine...

Top speed? Who knows - it'll bury the speedo without a problem.

Edited until we can better confirm (and prove) any times posted with better ability (by taking it to a track or a better controlled area).

Did the 84 SE come with a 4.10 or the 3.32 rear end? Or was it an option either way?

With around 130K miles on my 87 Duke I decided I would take it to the drags (Brotherhood Raceway in San Pedro) to have fun and try to sharpen my reaction times.

The best time I got with the whole treatment of taking out the spare tire, putting an ice bag on the air cleaner, (I even took out the air filter for this single run), straight pipe instead of water box and then turning on my radio REALLY loud was a blistering 17.1 seconds down the quarter mile.

I had the time slip in my Fiero note book for a while until the ink faded away. I can't remember the final speed (it wasn't that fast at all, maybe high 70s, low 80s.). I may have written it down somewhere but would have to dig it out of storage.

Bummer was that I never got to go back when I got my Hooker Tri-Y header. The place was torn down. It was actually down the street from where the final scenes (crashing of the Charger) of the Fast and the Furious was filmed.

It was turned into an asphalt plant....

Haha. You're not serious are you? You're telling me (and everyone else) that green 4 cyl Fiero is faster than any stock V6 Fiero?

Primer is my favorite color...

I'm only telling you what our Fieros can do. Only you know what your Fiero can do.

fiero5: It WON'T do a 6second 0-60.. It won't matter that much from car to car.. the rest do 10second+, and you got the freak car with 100 extra horsepower? Don't mean to sound like a total dick.>It's just not possible. What, are you just watching the speedo and counting? Your speedo is probably WAAAY off..

Rude of me, lets just say I doubt you have any connection with the concept of truth and reality.

i got a 2.5L 3 speed automatic fiero and it probably does like 1 minute in the 1/4m it can get to a nice top speed may be 115mph in the highway but it takes it a wile,but i guess you cant expect any better with close to 200,000 miles on the odometer, lol i guess i got the slowest fiero until i get the engine swaped for a 455ci pontiac engine. lol

------------------
mod it until is perfect.

fiero5: What does my car concern you of? I know cars.. and 92 horsepower will NOT give you a 6second car.. Are you sure you don't have a v6? It's just not possible. I challenge you to go to a track and get an actual 0-60 time. I bet you'll be shocked..

That is correct Mary Jane, 18.63 @ 70.14MPH was my best, I my 60' time was in the low 2.5's. I have the 3 speed auto, that I shifted manually (18.9 otherwise). That was my 3rd run out of 5, which was my first time at the track.

My car has 152000miles on it, with only a port matched and polished head and TB, with no cat (but a 20 year old stock muffler). On that run, had a full tank of gas (filled up 8 miles before the track), I had my spare, jack, tire wrench, interior, and everything else installed, and a 10 MPH headwind with 1200 ft of elevation. Plus 50lb of my stuff. Also, my car was dirty, shoulda polished it so it was more aerodynamic

EDIT: I dont know how to polush a car, so I corrected it to Polish

Times on a stock Iron Duke? Don't know.

My Duke is 'tweaked' about as much as one can be. My Friends G-tech says about 102hp/130ftlb to the ground, so that means 117/155 or so at the flywheel. 0-60 is in the high 8's, low 9's. 1/4 mile in the Around low 17's. More than adequate power if one can drive. (smile!) I don't find Fiero5's figures out of concept. But then, a Duke is not a "power engine".

But then, I don't drive a Fiero to impress people; I drive one cause I like to drive the car.

I gotta say 6 sec 0-60 times wow. Do you have any mods done to your 4cyl.

1984 Pontiac Fiero S/E 10.9 17.8
1986 Pontiac Fiero GT 8.0 16.2
1988 Pontiac Fiero Formula 8.0 16.0
1988 Pontiac Fiero GT 8.7 16.4

Found this http://www.angelfire.com/pa3/ford/performance1.htm

I have never heard of a stock v-6 doing better than 7s. If your 4cyl is stock I would have to say . Even with the 4:10 4spd the times were not that fast. Even this site which is very optimistic about Fiero performance does not show one as being that fast. http://www.60degreev6.com/download/fierofunfacts.txt
