We took my dads 88gt to the track yesterday.It ran a best of 15.6 at above 4000feet.AT the Fallon NV TopGun raceway.
His car has New High flow cat's and a flowmaster 2.5 exhaust.And a BBK cold air system.
His car as over 100000 miles on it.It's in great shape.It's a 5spd with 3.08 rear gears.
Dose that time 15.6 @ 88.5 MPH in the 1/4 seem slow to you guys?SCOOP ------------------

Well, it's hard to say without looking at it. Yes, a 5.0 in good shape should run faster than that(ex: before my 1.7's killed my factory springs I used to hit 100mph in the 1/4). However, the car could be in good shape but have a few things that could use replacement(wires, plugs, cap, rotor, coil, air filter). Check the car over, check the timing(I once couldn't get over 90mph and I found out my timing was at 4deg  . Make sure the clutch isn't slipping. Give her a lookover and let me know what you find. There are ALOT of things that can cause a car in overall good shape to turn poor trapspeeds. Let me know what you find.------------------

Wires could use to replaced all org.The cap and rotor are both new.New plugs the clutch is a great shape it only has about 5000miles on it.
His best 60's was a 2.4 no traction even leaving at idle.
The timing is at 10 degrees.
Coil is org,never replaced.
The air filter new K&N this summer.
Thanks for the help.He was not happy losing to me at the track.  SCOOP ------------------

10deg? Ahh, well the first thing I would do is advance the timing to around 14deg btdc or as much as the car will take w/o detonating. E7 heads make the most power just before detonation. Check the wires and make sure that they aren't arcin'. The coil is "probably" ok, but it also wouldn't hurt to replace it. You can have it tested at a local parts shop though. Don't buy into the TPS adjustment stuff that some people might tell you. It can improve your throttle response but it will do nothing WOT. The voltage that indicates WOT will remain the same regardless. It might also be worth while looking into some other basic tune up items, such as the fuel filter and other things that can decrease performance. A properly tuned 5.0 w/ good compression should turn around 96mph stock. You will probably get slightly lower trap speeds due to your altitude though. I *might* be able to tell more if you could post the whole timeslip. But currently I can't think of much else off the top of my head. If you are looking for mods that won't cost much: Underdrive pullies, short belt, cold air(if you do'nt have the K&N OUT of the engine bay already), and gears. None of these modifications are particuarly expensive, and most will yeild mild to moderate performance increases. The most bang for the buck though definatly comes from gears ------------------

Fishtail thnaks for the help.He was so unhappy to have added the new exhaust and CAT's 02 sensors and BBK cold air system.And run those times.Heres the whole slip. 2.387 60 foot
6.659
10.171 1/8th @ 69.88
13.199
15.74 @88.86mph 1/4 These times are all about 2-3ths faster then when he raced the car 7years ago,all stock.
He just put on this summer a cold air in fender system from BBK with a new K&N filter. He is thinking about going to a 3.27 gear.He dose not want to much gear.Being he drives his on long trips a couple of times a year.
I think with the corection he would be running about a 15.10 et? SCOOP ------------------

I've seen stock engine 5.0's run those exact times at Sac Raceway. One of the Mustangs I saw run a 15.1 belongs to a fellow Monterey Mustang club member. His 5.0 is a '94 or '95 and he has 4.10 gears, but no other major mods. No offense to yer pop, but is it possible a little practice might help? I dunno how much experience he has, but I've seen a buddy of mine practice so much he went from running his car in the mid-14's to getting into the high 13's on a consistent basis, with no changes to his car. I bet Alex could help with tweaking his suspension so as to get it more 1/4 mile friendly, and still be driveable on a daily basis.

Stewart you should know me enough by now to know you cant offend me that easy.I'm sure pops could use alittle pratice.He's an old time street racer from the Van Ness blvd area.He used to race his new then 66 GTO 4spd 4.56 gears alot.He really dose drive his car well.The guy can shift real fast,and smooth too.He's not looking to get into alot of mods,maybe some ET tires for the track,and some 3.27 gears.SCOOP ------------------

Well like Stewart said it's not unusal for stock 5.0 gts to run those times. However, they can be made to go faster. I know a few fellas around here with stock motors going 13's and one with a stock motored coupe that runs high 11s!!!(he races proff with that car though). Regardless my motor clicked off 100.67mph in stock form. Though be it at a much lower altitude. You can tune the car to run better, and the gears will help some. the slip looks fine, i was looking for an idication of something like a clogged intake tube(mine ran great unti the 1/8th) then it died. try some of the basic tune up stuff, see if it helps.------------------

Scoop I would tell dad to go with 3:55 instead .Cruising will be fine and it will ave more punch.You also said he drives it well and shifts fast but is he power shifting it? I mean is he holding it to the floor then stabbing the clutch and pulling his gear?It also helps to preload the shifter meaning after you pull say 2nnd gear put pressure on the shifter before your ready to pull third .Also only push in the clutch enough to shift gears.Its alot to remember but it helps.Some sticky tires will really help.Also does he have the stock headers ?If so they are restrictive as heck even for a stock 5.0 get some egual length 1 1/2" shortys 1 5/8" is a little big for a stock 5.0.
Hope I helped.

Bob very bit of advice helps.
Thanks he shifts dam fast and the car never seems to loose any any power.On the shifts,he dose not let up on the gas to shift.I cant beleive how well his car has held up.He drives his GT like it was built to be driven.I've been trying to get him to try the 3.55 gears instead too.
The headers sound like good advice too.

Hey Scoop,
Sounds like Pops is a speed shifter from waaay back!!! Those Fox bodied 5.0 hold up like you wouldnt believe.My buddy has an 89 and it was burning oil so he took it to the dealer for a warranty claim.They wanted to do an "oil consumption test" on it before thy would warranty a new motor.To make a long stry short we did everything in our power to blow that thing up and couldnt.We did get it to blow some serious smoke though.And he got a new short block out of it.Eve got them to install an e303 cam for him.

I'd recommend 3.73's over 3.55's. I read in some magazine awhile back that 3.73's are much better overall than 3.55's. ------------------

Boss302 I will say that 3:73's are a nice gear but, they are not for everyone.I dont think he wants to give up his ability to do some freeway cruising.If it was an auto I would definately say 3:73. I used to have 3:73's in my 93 lx and my buddy has 3:55's in his 89GT .I used to be able to pull him off the line a little but we would always end up evened out. we both had the same mods but the earlier 5.0's had a touch more horsies than the 93.I still think that the 3:55's are a better choice in my opinion for an all around street gear.

The elevation that you are racing at is not condusive with low et's, I have raced at Calgary which is also very high elevation. I was not able to break into the 14's there either.
I have grabbed my slips and this is what a couple of them were:
60......2.487
330.....6.600
1/8.....9.888
MPH.....75.24
1000....12.699
1/4.....15.087
MPH.....94.26
I had one better run as far as ET but do not have most of the numbers but here is what I have:
1/8.....9.766
MPH.....75.03
1/4.....15.002
MPH.....93.13This track was at 3500 feet (dont recall what the effective elevation was that day but it was not good) Here is a run less then a month earlier then the ones above, and this was at my home track which is around 1625 feet. 60.....2.211
1/4....14.686
MPH....93.757 This was with 2.73 gears. I dont honestly see anything wrong with your dads times at that elevation. But as far as the gear swap let me tell you a story 3 or 4 years ago a friend of mine (Lyle) was always talking about these friends of his from just outside of chicago. He told me that this man was a ford god, and if he didnt know the answer to my question, that there wasnt one. I would call this ford guru on the phone from my hotel room late at night and pick his brain about what i should do with my ragtop. The topic of gears came up one night, and he told me that I needed 4.10 gears to be able to make the car run the way it should. I had run 3.73 gears in the past, and thought that they would be the most that I would want to go with. I ended up going with a set of 3.55 gears which was for the most part very dissapointing even after having 2.73 gears at this point. Later on in the year I traded my 3.55 gears for a set of 4.10 gears, and could do nothing but kick myself for not having went with them in the first place. If you have not figured out yet who the ford guru is yet, it was the first I had to do with our very own Alex, it only got better from there(believe me he knows his stuff!!!). Personally I think that with a 5 speed a 3.73 gear is the very least that you should have, and go up from there. The best fuel economy I ever got was with the 3.73 gears. One common misconception about gears and fuel economy is that the less your motor is revving the better the fuel economy will be. This is not true, it is all about efficiency the motor is not running efficiently at 1400 rpm under load, it is lugging and not running at its fullest, add some gear, and get the cruising rpm up a little closer to 2000 rpm you will get a cleaner running motor, and along with that is better fuel economy. Dont Fear the Gear!!!! ------------------

Say it loud, Ed!Dont Fear the Gear!!!! Alex told me the same thing. And while he convinced me on the 4.10's, I'll end up having 3.73's put in only because they were FREE babeeeee! Free R&P gears thanks to Nancy (Stang4me)!!!! She gave them to me last year. I hope to have the rear rebuilt soon, and would like to upgrade to 5-lug while the 5.0 is down anyway, but either way, I'll have them puppies in there before it's completely back to daily driver status.

Thanks Ed,that helped out alot.
My pops dose not race his GT alot.So I dont see going to 4.1 gears.I keep telling to at least go for the 3.55 gears.He is building a 23T kit car that will be built for speed.
It's starting out with 4.11 gears,that was the 1st thing we did to it.Alex never let me call him late at night,or anytime. 
I know he knows what he's talking about.Thats why I try to do what he and few others on here say.So far it's all paid off big time. SCOOP ------------------

Scoop no matter what people tell you about a steep gear.Please keep in mind that with a mustang (stockish) you will never run out of gear before you run out of power with lower gears I had a higher top end in 4th gear with the 3.55 gears because you just dont have the power to overcome the wind resistance. You are in essence totally wasting a gear, instead of putting in a steep gear that will keep you in the powerband at all times. I love my 4.10s for regular street driving ( i am not sure about it now that I have the C4) with the 5 speed, and highway trips. So far the most I have on my car was a cruise to a neighboring town about an hour away, and it was a joy to drive Talk your dad into the gear, that way he doesnt have to kick himself for not doing it in the first place. ------------------

Checking the timing is critical. Most 5.0's respond nicely to 14 degrees and some can handle more. I run 16 degrees in mine using 93 octane without a problem. I have 3.55's in my car and love them - they made a huge difference in the cars performance over my stock 2.73's and are still a very easy cruise on the highway. Going from 3.08's to 3.27's is not worth the cost or effort IMO and yes you could get 3.08's in place of the 2.73's as a no charge option back in those days. If you can, buy or borrow a set of drag radials and see the difference they make - its amazing and they dropped my 60 ft times from the 2.30's into the 2.0 zone. This may sound dumb but if you have not checked it, make sure the throttle body opens fully. I bought my car new and drove it for 3 months before I discovered that with the pedal to the floor it was only opening about 80% of the way - cheapest "mod I ever made.Bone stock my car ran a best of 14.44. Adding a K+N, shorty headers, timimg bump, 21/2" Hi flo cats with 2 1/2" flos, underdrive pulleys, the 3.55's and a set of BFG drag radials it ran 13.89 with a 2.02 60 ft and it still has probably another tenth or so in it------------------
