I went 14.38 and 92MPH 2.0 60ft with a series I S/C totally stock, & 5 speed getrag.
19" wheels street tires.

It was my 1st time at the track and it was 99 degrees and humid. THEN later I found out I had an NA computer chip!!!!! Thanks to Darth Fiero for fixing that!!!

Obviously should be better this year.

best time of 16.75 85 gt v6 3spd auto.

tonight in the humidity and yuckyness i only got down to 16.98 *eyeroll*

i need to get back to the track.

PS: I like the new format, kinda wish Cliff could start a dedicated section relating to performance and stats. For example it could list things like:

1/4 mile times
Top speed (drive at your own risk)
braking distance
lateral G's
road course track time (dunno how we could standardize this one but it is an idea)
weight
etc etc etc

Gonna give this a BUMP! I've been looking at engine swaps lately and this post is good refrence to decide on what motor. All depends on how fast you wanna go.

------------------

88 Coupe 3.2L V6
60* V6 Power Baby!

almost done with my 3-spd-auto to 4-spd-manual swap - should have a new time for this soon.

My 85GT actually posted 15.474 (@87.38) last season. It is now carbureted and untested.

It ran as a 4 speed Muncie, stock, CRX intake and MSD ignition.

Man , I only see 4 4.9 Caddy's listed. I'm wondering what mine would do. Hopefully will get a run done sometime. With all the talk about the 4.9's on the Forum , I figured more would post numbers. Kinda want to see how a stock 4.9 compares with the rest of the crowd.

well, hopefully, cplensdorf will have his 4.9 ready soon to, and we can go hit Milan together

I could add expand on my quarter mile list, but nobody seems interested. https://www.fiero.nl/forum/Forum1/HTML/042986.html

What RPM is your converter flashing at? Im thinking if it was higher you would see a better 60 foot. Your tranny has a "shift" kit im assuming.

Finally made it to the track with the new mods. The last time I was at the track, I ran a 12.79, but I have since upgraded to 3" mandrel bent exhaust and a bigger intercooler (modified stock GN).

Got to the track tonight, using 93 octane pump gas with Klotz Hitrate octane boost additive this was the result:

12.381 et @ 110.03 mph with a 1.784 60 foot.

I am thinking either a cam or rocker upgrade might be in the future...11's don't seem so far away now.

By "flashing" do you mean stall speed? It is set at 2100rpm for a stall speed. The shift kit just makes the shifts quicker but doesn't change when the shifts occur. I think the 60' time may also be the jets in the carb. I'm still using the .51 jets so it seems to be slightly rich at the low end. (New jets are on order, actually it's the entire tuning kit. )

Cool deal Darth! Great times. LILDevil just added an intercooler to his and ran 12.26@112mph in 90 degree weather! He should be in the 11's when the temps drop!

BTW, I will update the list when I get time, I must sleep now, 12 hours at the track without a car SUX!

Yea, I pulled a bone-headed move and didn't think to take a chip along with any more than 20 deg of timing. I was running 18 on the street but with the octane boost I was running 20 deg timing and 15lbs of boost with 0 KR so it could have been pushed a little more. Even that 1.784 60' time was with a little wheelspin launching at 2lbs of boost. I tried launching at 6lbs but I blistered the tires and came off the line sideways. I am thinking some drag radials and more timing should yeild a couple more tenths but I really want a cam because my MPH in the 1/4 is a little low which is telling me I am not making the HP I would like but the TQ is definately there. Still tho, 1.784 60' on 225 55R16 BFG Traction T/A's is not bad at all. These are definately the best street tires I have ever used.

Wanted to share the times of an impressive 84 SE "sleeper" that raced at the WheatStock Drags today. The times were witnessed by multiple forum members and I captured his best run on video. The owner is not a forum member yet but he said he would join soon.

Details:

Owner: Ralph Degenhardt ( works as a transmission mechanic)
Location: Heartland Park Raceway , Topeka, KS
Date: 6/26/2004

Car: 84 SE Notchback
Engine: 4.3 V6 with cam, Vortex heads, 500CFM Carter AFB carb, homebuilt 1.5" headers
Trans: 4T40 with 2100 stall, modified clutch packs, 3.06 Final drive
Tires: 215/60R-14 Street Tires ( Mud and Snow rating...NO KIDDING)

Performance:

ET: 12.504
MPH: 107.94
60' 1.783 sec.

Car was very plain looking but ran exceptionally well...

NO nitrous, turbo, blower, or racing gas. He drives this thing on the street almost daily.

His performance makes him the quickest and fastest naturally aspirated V6 Fiero that anyone has reported. There isn't another naturally aspirated V6 that is anywhere close to these times and speed.(12.50 vs.13.80's....)

Kerry

bump so i can find it.

NOS3800, My fiero is a 3.65 4 speed Muncie. Please update the list.

------------------
5 car lengths in front of you and still pulling...

Jesus Ryan. Thats an awsome 60ft. Im going out on the 9th, hopefully ill beat your time

Just a quick question for someone to answer. How do I find out which gear ratio my 4spd is on my 86 V6? I think there's only the 3.65, and 3.32?

post this is Tech and you'll have better luck - I wanna know this too

quote Originally posted by sqoach: Just a quick question for someone to answer. How do I find out which gear ratio my 4spd is on my 86 V6? I think there's only the 3.65, and 3.32?

The ratios are as follows:
1984
3.32 Base coupe only (muncie 4-spd)
4.11 Sport Coupe, SE and Indy (muncie 4-spd)

1985
3.35 for 4-cyl (Isuzu 5-spd)
3.65 for V-6 (muncie 4-spd)

1986
3.35 for 4-cyl (Isuzu 5-spd)
3.61 for V-6 (late 86 getrag 5-spd's only)
3.65 for V-6 (muncie 4-spd)

1987
3.35 for 4-cyl (Isuzu 5-spd)
3.61 for V-6 (getrag 5-spd)

1988
3.35 for 4-cyl (Isuzu 5-spd)
3.61 for V-6 (getrag 5-spd)

if your trans is a stock mated to a V6, then its the 3.65 FD. only about 6k 3.32FD trans were made and they were all in 84. The other 84's were 4.11FD which is most common.

I ran a 15.8 on a stock high milage formula. 5spd, 165k miles. At around 83mph. Same car is getting a better engine.

Here's a couple quad 4 cars for ya:
Me: 16.1 with a 2.44 60'
Comealongway: 15.9, with a 2.3 60' I think (not sure on the last one)
Hopefully I'll see some improvement over the summer.

Thanks guys. I guess there's no question as to which 4 spd I have

another personal best: 12.51 @ 107.87 mph 1.75 60 ft.
