Hey you should come down to Houston and have my guy help you out with your tuning. He's on ZZP's website as a preferred installer and he has a shop that specializes in 3800's. Your car should be able to hit the 11's with a really good tune I would think. Let me know and I'll forward his info to you, or actually just contact him on here, his name in Tengis.
Thanks, for the info. I have contacted him and am just trrying to work out a time to meet up. He was scheduled to come to dallas a few weeks ago but could NOT make it. I may need to go to Houston and get tuned along with some tuning lessons.

Yeah I remember him having plans to do the Dallas thing, don't remember why it didn't happen. Zack's a great guy and has a lot of talent. You won't be disappointed I'm sure. Depending on when you come down, you might even see him wrenching on my car.
I found a reference to a 370 hp fiero 4 cyl that turned a 9.72 at 134.41 at the keystone nationals on sept 15 1985 in a comparison of an 88 fiero to a 308 ferrari. Wouldn't there be a confirmation in the records of that event. If there is we're still trying to beat a record that was made 25 years ago.

Nice time man! Looks like a bit of tuning helped! The times I trapped 109-110mph I only ran in the 12.6-12.7 range. Looking at my old slips, it looks like your 60ft was about .1 faster than mine though. Nice launch! I miss cutting 1.7 60fts. I have a hard time getting a good launch with the turbo.
If all things go as planned, I'm hoping to be posting a new pb here in a few days...

The Vette did have a bad start because of a late reaction time but still....
That's why, the timers don't start until you start moving. You left before him so your timer started first. So, while you did beat him to the finish line, he traveled a 1/4 mile in less time.
Got to get out to Milan before the season ended. The engine has been back together and it has been back on the road for 3 weeks. A few minor bugs to works out.
Very happy with the results. Previous best was 13.32

The original 99 L67 spun a rod bearing. I got an L26 from a junkyard and used the short block. JustinBart and Darkhorizon did the wrenching, fabricating and some pretty clever 'on the fly' engineering.

hot D@mn! that is some great time Terrance... nice 60'!!
as for the tape job, it is definately true that the more slippery the car, the lower your CD, which should lower your time(s)... though I have never seen it done to a Fiero before, nor how much it would actually help.
It certainly would help at high speeds... and I reckon 112mph qualifies as high speed!
The other guy was pretty fast too... what was he running?

Did you find some race gas?... how much $$?
I came by your way (in the country) and picked up a few gallons of the 109. However, they had some @ the track and will get some there next time and save myself a trip.
The other guy was some kind of Vette, not sure which model 12.3 and a 1970 Ford pickup 12.5. I also ran a "real" Zo6 Vette and he ran a 11.5 while I spun tires @ the line. After I saw his 7.0L V8 with an upgrade Fast intake and CAI, I guess I got a little too exicted and over did it at the start.
I raced the same Vette as last time but this time the results were in reverse, I ran the 12.0 and he ran the 12.3 but he beat me to the finish line. I guess I need to stop winning because I trap better times.
Sounds ridiculous, but you'd be suprised how much aero drag works against you even at 60mph... as you go faster, drag force increases exponentially.... double your speed, quadruple your aero drag force.
0.017 seconds isn't much. Lower your coefficient of drag and you'd notice a difference. Wouldn't hurt your cooling system for one run down the track.
Man you are almost there....Some DR to take care of the spinning which will cut you a better 60' and you are in the 11s....
About to pass up my PB...can't let that happen....I better get to work on something......
I wish I had time to pick up those DR's before the weekend. Oh well, I am happy with my times although I am still positive I can run 11.88 with out them. I just have to prove it and then back it up with another run.
All you need is a tune, and 11's are "easy" for your setup. DHP powrtuner rules !!!

Sounds reasonable. What would you use, Duct tape? Also do you think the GT spoiler helps or hinders the Fiero in the 1/4 mile? Is it for show or go?
The GT spoiler at stock height probably doesn't have much of an effect. It sits low, usually in pretty turbulent air anyways. Probably more trouble than its worth to take it off.
I don't know if I would use duct tape on the front, not sure if its paint friendly. Maybe someone else can chime in with a better idea. I think it would be a cool experiement to do a couple of runs with it on and a couple with it off. See if there is a net difference.
I did not get to do alot of testing on this, but popping the hood on steve25's setup gave him about 1.5mph extra at the traps.
Terrance is running a vented hood... but nevertheless... that sounds like good thinking.
edit-- maybe that painters blue (masking style, the widest they sell) tape would work. Though not real stiff, it should not harm car paint. A lot of people put it behind the rear wheels to prevent burnout build up on their paint. Or run with a car bra--- put duct tape on that thing... it wouldn't care. Just clean up any sticky residue with some goof off or gasoline.

I have always used painters tape for track only mods like that. Toss some on the wheel wells to keep rubber off, and then some on your headlight doors.

Close. If you double the speed you square the force.

Its the same thing... If you take a number, square it, and then take the original number, multiply it by two and square that, you get 4 times the original value squared...

Interesting, and true, but unfortunately that is neither quadrulped nor relevant.
Speed is a scalar quantity commonly expressed for our interests as Miles Per Hour or Kilometers Per Hour
Aerodynamic friction, can be written as a force, -apAv2/2, where a is called the aerodynamic drag coeficient, p is air density, A is the effective frontal area (cross section) and v the speed.
We could not have a meaningful discussion of Aerodynamic Friction without involving Bernoulli's Principle and some fairly serious physics.
In an attempt to restate the discussion so that a layman might have a feel for the dynamics might I offer this admittedly oversimplified example:
If at XX MPH the effective force of Aerodynamic friction is resolved to and expressed as pounds of force per square inch of effective frontal area of the vehicle as YY PSI then at
2(XX) MPH the effective force of Aerodynamic friction will be (YY)^2 PSI

I think I speak for most of the people who have read this post when I say.... HUH?!?!?!?
I'm waiting til fall. Summer in Florida is not a very good time to go drag racing.
Not that my Fiero is really fast or anything, so it doesn't really matter. I doubt anyone is sitting on the edge of their seat, hoping to see me break into the 14's.
It would be cool to see what some of the faster guys are up to, though.

Both of you are correct, of course. Drag *FORCE* goes as (is proportional to) the square of speed. Double the speed and force goes up by a factor of four.
Drag *POWER* on the other hand, goes as the CUBE of speed. Double the speed and the required power goes up by a factor of EIGHT.
This is why a Bugatti needs eight times the power of a stock Fiero to go twice the speed.

I see sub 12's in my immediate future.
