Oh heck no.... I have a range of about 15 miles. Very fast miles but only 15.
We are going to try the TEXAS MILE in Beeville Texas on Maqrch 23rd this year. Registration is complete and license applied for. Will try to do 150mph crossing the line. That will be at half current to keep heat down.
I know I was just giving you a hard time. It's very impressive but a hard claim at streetable.

If you can hold off until October I'll have my Northstar car there...
I wanted to hold the title for the fastest *documented* Fiero in the world for at least a little while

Well, this year is gonna be interesting as I can see. My first event is in Jun, so have to stand back till then. There is some serious mods underway right now, but all in the right time Teaser would be -300lb and fixing trans problems that netted me 2sec 60' times.
I am pretty sure he has timeslips photos here somewhere. As I said there is video of it on youtube if you search it.... nevermind here ya go... http://www.youtube.com/watch?v=5li6oojNCIM
So while he is kind of a wiseass and annoys a lot of folks here you cannot discount the fact that he is a major player in the fiero speed circles. I for one wish he would cut the bull and really let that car go on the track and let us all see the nine I think it has in it... would be awesome. Peace

Yea, I hate to be a pain, but I can't read anything in that video that upholds his time claim except the title.
I looked through the thread and didn't see a slip he had posted except for the one earlier. He is a pain to everyone here, and a jerk as well about this crap. I'm just saying he needs to post realistic proof like everyone else has to.
I see what you say about the 0-60 time. Were you just being careful or was there a complete loss of traction off the line?
Easing into the run in 1st, no traction in those first 2 gears at 1/3 throttle and finally being able to hammer it in third. Crossing the line in fourth and headlight lids popping open as soon as I go over 120...fiero airbrakes? Next time I will bring some duct tape and maybe launch in 2nd!

Just pop the hood and No Air Brakes. There are also a number of hood venting solutions too.
Get some good soft compound summer tires and bigger wheels 18's+. It makes for a faster launch because bigger tires are harder to spin and you are covering more ground. I can launch very good with my 18" wheels and street tires with no spin but I sure as hell ain't trapping 120+......that is until I go Turbo
Bigger as in overall diameter? Hurt, not really as with too much powah you WILL break traction. You need a handicap so you don't spin and Bigger and Heavier Diameter wheel\tires will do the trick. Moving forward is ALWAYS faster than standing still ask that ZR1 owner. Also, a Virtual gear ratio is created due to the bigger diameter netting a faster speed @ given RPM.

Wheel and tire are two different things. Tire diameter is not the same as wheel diameter.
Large diameter wheels just absorb more power (especially at the fast end of the strip).
It's also easier to get off-the-line bite with a taller more compliant sidewall.

Makes sence, as I was implying to reduce tire spin a bigger overall diameter will do the trick. As for asorbing more power does that equate to more speed too???

That means it takes more energy for the engine to spin up the larger diameter wheel, which means there's less energy leftover to make the car go faster.

Bigger wheels and hood vents means no more sleeper for my street car. I will have to try "hood popped" and taller rear tires on stock fiero GT wheels. I think with less tire spin I can get 2.0 in the 60 ft time and maybe 12.5. I am not going to be dragging the car all the time. I prefer it as a daily driver/show car that gets 20 miles per gallon combined city/highway and can embarrass most cars on the road with its innocent external look.

You should invest in some drag radials. Most people won't notice what kind of tire you have. I know I won't go back to anything less than a drag radial on the rear, it's just so much safer.

Couldn't Hold Off. We ran a 134.5mph 1/2 mile and a 155.0mph full mile. Video Here....

Congratulations on creating an incredibly fast fiero. In October, the outside temps should be cooler for the Texas Mile event on Oct 26-28 (if you plan to run again). Do you think CO2 cooling of the battery pack is wise to keep temps down? What theoretical top speed is the car geared for?

Thanks. Cooling, the batteries don't like cold temps. In fact, we usually warm them up on 1/4 mile days. On the mile it is a race between the motors I^R heating and the batteries I^R heating. They are both matched about the same for 1/4 mile racing at around 10 seconds at 2000 and 2500amps respectively. It would be cheaper to blow up the motors than the battery so I think I would prefer to put more battery in there and push the motors a little harder.
Gearing, Well, I have never had the car over 4400rpm. My modeling has the car heading to about 300ft lbs of torque at 5252rpm. The actual point at where the drag meets the rpm and torque with the current single gear and an overdrive 1/2 gear appears to be 180mph. But we take for ever to get their like an asymptote. So top speed in one mile with this gearing and pushing the pack a little more is predicted to be 175mph.
We could think about a second gear vendors overdrive called a "multi" they sell in their catalog. That might get us to 190???

A battery's "voltage performance", which is the voltage it puts out at a given state of charge, goes up with temperature. A warm fully charged battery will push more current to the motor than a cold battery.
The battery's self-discharge rate due to leakage current goes with temperature also. If you want a battery to stay charged longer, keep it cold. That's why we store flashlight batteries in the refrigerator... they last longer in storage. That's also why they don't put out much power when you take them right out of the fridge and put them into a flashlight.
That means it takes more energy for the engine to spin up the larger diameter wheel, which means there's less energy leftover to make the car go faster.
In your opinion, What is the Optimal Wheel\Tire size for the 1/4 in a Fiero?
I launch very well with my 18" and Corvettes come with 18" and 19" from the factory. I average 1.75 60' and evern have murdered cars with Slicks from a launch.
The ONLY street car that has held it own with me from a launch is an Nissan GTR. All other street cars get the smackdown from 0-60.
When I had the stock 15" I spun way too easily and my assesment was that they were too small and light. Also, the tire compound was probably a big factor too.
You want the smallest diameter wheel that will give you enough width to get a good contact patch.
It's difficult to run much wider than 7" in a 15" wheel. I'm running 16 x 8's on the rear of my car. I haven't personally looked into drag radials, but I'd suggest starting with a 16x8 and the widest DR that will go on an 8" wheel.

Where were you when I was shopping for my wheels?
Never mind, Don't answer that as I DID read the Threads!
I run a 27"X9" 225/60R16 Eagle GT on 16"X7.5" like on the 9.898 run.
or sometimes 255/50R16 BFG Drag Radials deflated to 16psi if the track is uber slick like after sundown at Baytown Royal Purple. A little shorter this is better for 1/8th mile ET.

I'm running 255 Mickey Thompsons on 16x8 grand prix mesh wheels on my 84 with coilovers.
I have those wheels. I used to run 255/50 Firehawk SZ50 EP's, but that size is getting harder and harder to find. I had to switch to 245/50's this time around.
The offset needs to be 25mm in order to fit the 16x8 on the available knuckles.

I have a video I can post up soon, it's not the greatest, but I will still post it up.

Congrats Lfiero67, I would bet we will be seeing a nine second NON-electric fiero on here REAL SOON!! Good luck tuning that monster man and please keep us posted on the progress. Very nicely done. Peace
Teaser would be -300lb and fixing trans problems that netted me 2sec 60' times.
I have been hard at work faking videos though.
