Whats the best time or average time 0-60 with a 2.8 auto. I have an 87, just tuned it, new plugs, wires, coil, pickup coil and distributer. Can bearly make it in 10 seconds. This seems slow? I'm not read lining it but I'm pushing it hard.

that seems really slow!
I wish i could help you but sorry, im not help here

hope you can figure it out

I would check your exhaust. I know a lot of us have had catalytic converters go bad. I took out my cat only to find it's entire contents had already been emptied into my muffler which I then had replace as well but it certainly made a big difference in the end. Good luck to ya,

'86 GT T-Tops 65K miles and lots of fun

The approximate time was around 6 to 7 seconds. Seems like 6.2 if I remeber some of my old specs from when I was a DSM for PMD in the 80's and kept up on the car mag reports.

hmm.. a 5-speed can make it 0-60 in about 7.2 seconds i believe.. why would auto be faster!?

Sorry I thought I said approximate time and now that you mention it I think it was 7.2 on a stock 5 speed. The auto would not be any quicker most likely but sometimes depends on the driver. 10 seconds is definetly a little slow.

0-60 in 7.4 sec, consistantly.

About four years ago I did a mild overhaul on my '86 2.8 auto. Nothing much more than a quality job done, no real hp enhancements.

Each year I put a 190 lb friend in the passenger seat with a stop watch, and we have averaged 0-60 in 7.4.

Most of the magazines of the time that tested the GT 4 or 5 spds came up with times from 7.5 to 8.0.....most nearer 8.0 from a NEW car.

I consistently get 6.8 0-60 on mine, but have reason to believe that the engine may have been swapped to a 3.1.....but not sure. It runs better than any 2.8 I've ever driven.

I would have to concur with Phil on the 0-60 test times reported by the auto magazines like Car and Driver. However, many of the times laid down were done with professional drivers so you may not be able to duplicate them easily. The zero to sixty time is also heavily dependent on FDR. In theory the Four Speed 85 GT notchback being lighter in weight than the GT but with the 4.10 FDR should be the fastest However,I'm not sure that the V6 ever came with this FDR gearbox.

I drove a 86 SE V6 for years...Around 10 sec is about right for 0-60 sec. They really were not as fast as quoted in the magazines. If anyone is interested I have it for sale.....

Mine also consistantly pulls mid to late 6 seconds.
Only mods are -:
Tubular exhaust manifolds, 2 separate systems, no crossover pipe, no EGR and no CAT.
And pulled the restriction out of the bottom of the air filter box.
Thats with the 4 speed manual.

I haven't timed my 86se auto yet. If I was to guess I would say like high 7's to low 8's. Just by the cars I'm able to hang with .

It's in good shape engine and trannie wise too...

I have run a best 0-60 in my auto 2.8 Formula of 8.65 seconds. It will run anywhere from upper eights to low nines depending on how well the motor is running that day. Thats not a magazine number, thats what the car will do if I lined up and timed it today. So be careful comparing it to magazine numbers, where they do whatever it takes to get the best time out of the car.

Speaking of that they do, I remember the review of the Honda S2000 when it came out. The magazine tester squeezed a 5.x run out of it to 60. They got that number by dumping the clutch on it from 7000K RPMS, or some similarly high number. If they didn't, the car was considerably slower. I don't think many owners of their S2000's are driving them like that. Just thought I'd share an example of how those numbers in the mags can be inflated... especially for the lower torque, high reving RPM cars.

My bone stock '87 GT runs 0-60 in 8.9 seconds consistantly according to a G-tech and also my old fashioned stopwatch method. And that GT has 120,000 miles and the motor is far past it's prime. Most seem to run in the mid-8's. If yours is truely taking 10 seconds, it's time to start looking the different systems (ignition, fuel delivery, engine internals, etc) over to find what is wrong. My coupe with the Iron Duke 4 banger and an auto hits 60 in the upper 10's.

Stock Fieros are not very fast compared to today's cars.

Mine is a stick so go ahead pass me up.

But for arguments sake, i run 6.7 sec in my 86 four speed fiero with a 95 camaro 3.4l, that was dumpin the clutch at 3k, and then ridein it to about 5k each gear, into third.

Somthing is amis w/ my motor though, it runs outa steam around 4k, so i think i have a plugged up muffler, cause when i took my cat off, low and behold there was hardly anything in there..... so i assume it is that....

BTW they are fast compared to todays car, considering if i put 500 dollars a mo. into the fiero i would spank my friends s2k, and considering he has no fun money, its all good for me.

Btw i rape him like a gorilla too 60

just my 02

Thanks for the info, it gives me a goal to work for. Lower 9s even sounds good but I would be thrilled with 7.5. Its possible my cat is bad, the only thing I haven't checked is the full pump.

Thanks guys!!

My stock 85GT Auto ran 7.5 all day long with just plugs and minor tuneing Once I took out all the extra weight and ran 7.0 but I like to have a spare tire on the street . It's a 3.1 now and runs around 6.5 full.

Tuned right a V6 Fiero should run atleast 7.5 but then again almost none of us keep our cars in perfect tune.

I'm looking for high 4's when I get my V8 done

Sorry to get this post off topic but I just wanted to post some benefical info.
The 3.4L in a Fiero DOES run out of steam bigtime beginning at 4000 RPM. By 4500 RPM the engine is really laboring. By 5000 RPM you have no more power than the 2.8L. Apparently Wester's did a dyno run on the 3.4L and this was the finding. The stock Fiero plenum/manifold just cannot flow enough air to support a 207 CI engine. The only way around this is a different intake system or a turbo.

This statement is profoundly true! There is absolutely no substitute for your own test data.

While you're at it, spend the $100 for a factory service manual. (Then use it.) It's probably the best investment you'll ever make in your car.

Yes at 4000rpm the restriction of the Fiero intake starts coming into play. You also need to upgrade the ignition system. Most GM HEI systems (with distributor) seem to run up to about 4500rpm but then the spark seems to stagnate and you have a weak spark for the higher RPM's.

My 86 SE with a slightly modded 2.8L (bored intake, Sprint manifolds, trans shift kit, and advanced timing) was running about 7.2 seconds 0-60 (measured with G-tech).
Can't wait to see what my 3.4L does.

Ok... Here we need to be careful and see what instrument people is using to measure 0-60. At least to me any stop watch, seat of the pants, won my neihgbor GT, etc. type of measurement is just pure BS good just for a gesstimate. Sorry. G-Tech & track slips are just the standard. I'm very skeptical of any below 7s 0-60 on a stock 2.8. Yes, out of 200K+ 2.8s out there some may be better than others but just a few. Stick cars depend a LOT on driver and launch. Saying all that, my best time for my stock 177K miles 2.8 auto Formula was 7.98s manual shifting at 6K rpm. When I added the 18" rims, F/X package, audio, dynamat, NX bottle 0-60 dropped to 8.7s. With bottle it drooped to 6.2s. With my stick shift red 3.4 Formula I have only managed 7.25s 0-60 with all the mods that you can imagine. Oh, and I forgot driver weight is important. Is not the same a heavy 285lbs person (don't ask who) than a 145lbs kido. Why do you think horse race jockeys are small & lightweight? To have more horse power!
