Hi - my question is how far will my 87gt go on 1 tank of petrol?
assuming everything is running in tip top condition with the only mods to the engine are a k&n air filter in the air canister and ported exhaust manifolds and y pipe.

all opinions welcomed

My best guess, without knowing anything about your driving style, if it is an automatic or manual, or if it be more city or highway driving, or equal amounts of both...... would be a rough educated guess of 446 Km on a single tank.

thanks john - it would be a steady 70 -80 mph on motorway/highway conditions and the car is a 5sp manual

jon

That would push it up, being both manual, as well as highway driving.... My second educated guess would now be around 510 Km / 317 miles.

It sounds like you are going in a road trip If you are, make sure to post back in this thread the distance you actually traveled on a tank. I have subscribed to this thread, so when you post back, I can come check and see just how grossly off my calculations were LOL!

Knowing the inaccuracy of a Fiero gas gauge I wouldn't push much over 250 miles. I can get around 30 mpg and with a poor pick up from the fuel pump trying to get the last gallon of gas out of the car can be a problem.

take a jerry can full of gas and try to run her dry. im sure you know already that running your tank dry is bad for your pump but im sure we have all ran at least on tank dry in our lives

I haven't, at least not yet! Im only 21 so who knows.
Im interested to see what this car gets for mileage.

5 speed, V-6 GT , 2,500 rpm=70 MPH. 28 MPG with cruise control on. I did push it to 270 miles.

I have stretched 250 miles at around 70 on trips, which would be about 402 kilometers in my 87 GT 2.8 but like I said I was stretching it and was a little worried.

I normally try to refuel at the 200 mark in my 3.4L Fiero. But I have pushed it to 250 miles.

I wont let it run dry - I just wanted to know so I can work out how much fuel would be used and yes John I am planning a road trip.

I will give you a basic run down and hopefully I wont bore you

when I was in my early 20's I got a job in Cyprus on a cruise liner working 10 months of the year.
At home I had a Ford escort XR3i which when I got it was a total wreck but I started to do it up - mainly because it was one of the first off the production line that ford offered with fuel injection in 1982.
when I got my time off at the end of each year I would work on the car - after my 2nd year at sea I had finished the car and got it sprayed up.
having to spend a lot of time away from home and the car completed I thought I would have a challenge.

My girlfriend at the time (who is now my wife) worked on the same ship took the easy option and flew over to meet our ship, which wintered near Athens Greece to have repairs etc.
Where as I decided to catch a ferry from my town in the U.K to Zeebrugge in Belgium and drive 935 miles to Ancona in Italy catch a ferry to patras in Greece and drive 2 hours and meet my ship which was a new ship to us but was a converted ferry with a car deck that didn't get used so the car went on there and shipped it to Cyprus. BTW My wife then said she would of loved to have done the trip with me.

The best part of the trip was Belgium to Italy going through the Mont Blanc tunnel the alps etc.

a couple of years ago a television chef entered a race in Italy called the Mille Miglia see here http://www.1000miglia.it/2014-Edition/
The rules are that cars can only enter the race if that model of car was in the original race years ago - he bought an old classic had the engine rebuilt and then decide to thrash it on the opening stage of the race which resulted in one of the valves failing.
The race starts in brescia and does a circular route via Rome and finishes back at brescia a few days later and a 1000 mile done.

now the providing I can time it with my job as I work at sea and my fiero is ready ( it wont be in mint condition as I would like it to be but never mind )
I plan to catch the ferry again to Belgium and do the same drive but stop at Brescia and watch the start and finish of the race then drive back and visit Lake Garda and surrounding area in between.

if I cant do it this year due to work commitments - I will do it next year

hope not to bore you but that's my plan and I will post pics and keep this thread up to date.

What about one with a 2.8/TH125?

I don't know, but where's that Kansas music coming from?

well as updates go - been trying to get the ac ready and working but yesterday while on a trial run the belt I think was little too tight on the compressor which seized it and nearly caught fire fortunately I was 2 miles from home after doing 150 mile trip.
and as the belt was that hot I was able to remove it without undoing a bolt (basically melted off)

So no a/c now - however this was the mileage I was getting every quarter of a tank equalled 50 miles the driving was very varied with a lot of gear changes and the roads were hilly in places (engine seemed to be lagging a little)

Today after a couple of checks and all seemed in order we went out for another drive and found that every quarter tank I was getting 65 miles again varied driving but mainly flat roads (probably engine didn't have to work hard as there wasn't an a/c belt)
and the engine seemed very smooth

I did however find the service engine light come on after cruising down the motorway at 90mph - however after I switched the engine off 10 mins later then restarted her the light went off (will check the codes later - but I am suspecting the pcv valve as there was a tiny bit of oil that had come out on the rubber tube.

so my plans next weekend are to remove the compressor (and maybe kick it around a little bit) and more test runs and hopefully it will be good for my road trip in may

A small vacuum leak will cause a code 32 at speed. Look for loose fitting elbows at the EGR valve and at the solenoid.

My car is a 5 speed manual and did around the same with the v6 as it does with the v8.

I know because I've take the same trip to Daytona with both engines and its around 258 to 289 miles to the tank at the speed you suggest.

Now granted it will do more but by the time it reaches that range I start worrying so I fill the tank up at that point.

I drove 485km yesterday on a single tank yesterday, and the gauge indicated I had just under ¼ tank left. That was almost entirely highway at about 100-110 km/h. I'm a five-speed 87 GT as well.

I tried to figure out how much fuel I used, but when I filled up, it took 33.38l, giving me an average of 6.88 l/100km, which is too low. I think I had filled the tank past where the gauge points to full before leaving, and only to full on the way back, so I might have snuck an extra few litres in that I didn't replace. I don't have the hang of filling this tank yet as the pump seems to want to stop pumping early and often.
