ug - we still here?
its 120 to 130 depending on many variables, including weather, gearing, tires, elevation, road slope, etc etc etc
we only have one documented speed by Toddster @ 123.77
gonna be hard to find a stock 2.8 to touch that, but stock was never in the question, so, this makes it even harder....
I know I could beat that....

Park your Fiero with the parking brake OFF and the tranny in neutral in front if a 60 mph wind and watch your Fiero go exactly....no where. The surface area of your Fiero prvides next to NO measurable area for wind to move it. Can we also try to remember that at 123 miles per hour you are outrunning your tailwind by 63 miles per hour! You might do better falpping yoru arms!

LMAO - wow, just.. wow..
using wind to accelerate a fiero from a state of static friction and moving it to a state of dynamic friction (you do know that static is much higher than dynamic)

second of all if you are traveling 123mph with no wind you have 123mph of wind resistance... if you travel 123mph with a 60mph tail wind you only have 63mph of wind resistance.. this means your tops speed formula will have two difference speeds.. windspeed(rolling speed - tailwind speed) to multiply with he CD and rolling speed to multiply with the CF.

thats what we all keep asking you..

I'm starting to think you are just playing devils advocate to stir up the nest for your own amusement..

Look, Toddster is either unwilling or unable to understand what we're trying to tell him. He's convinced he's right and we're wrong and nothing anyone can say will change that.

At this point it's like trying to teach a pig to dance. All you do is waste your time, and annoy the pig. Time to let this one go.

anyone have any actual non-speedo top speeds to speak of? we all know about wind resistance (to some degree or another ), rolling drag, gear ratios, tire sizes, etc....
I seem to remember someone mentioning a ~140 mph measured by on-board GPS - I expect its not a stock 2.8 tho...
I say, with a properly geared 6-spd trans, 140 from a 2.8 is no problem. just need to have a gear to get back into the power band. if you've ever tried hitting top speed, you see how sllooooowww the tach climbs past 4000. this is past the power band, and where the intake starts to suck (or not suck, whatever), and the coil barely sparks. next gear, drop back to 3000 RPM, and I bet you can get more. propably totally dog the motor before you make it to 4000 again tho....

All depends. At some point you will require more horsepower to overcome wind drag than the engine makes at peak, so no gearing change will matter after that. The highest possible top speed for a given engine will be with gearing that allows it to reach it's HP peak exactly at it's top speed.

i swapped a 1988 Honda Civic HF motor in my car with the stock tranny and now i can go 215mph!!! w00t!!!

guess what this is about how stupid this has gotten... the top speed of a STOCK fiero is in the 125-135 range... enough said supposedly my dad had his to 140 back in 86 with a STOCK 86SE auto but i seriously doubt it since ive only seen mine push about 117 and that was on about a 2% incline going strait. even my friends 91 240sx was pulling

right, thats why I was saying maybe 140. the gearing just to get back in the power band around 3000 RPM's. I dont have any math or science behind me - just using the force, luke

You really think you're that important? I stand by my posts until proven wrong in some experiment

I would've said the same things, whether it was you, Cliff Q. Pennock, or the Ogre making those posts.

"5/6 reasonable men agree, the fiero's top speed depends on many factors. The sixth man says 123.77mph period."

Teedertoddster took his ball and went home. To bad, this was amusing

I still think the top speed depends on how high you drop it from

That isn't called "top speed" It's called "terminal velocity"
