:evilgrin:
So, I had my buddy that drives a 2001 mustang gt try out my clutch. He did a couple clutch dumps and banged on the gears a bit. He says it feels like I doubled my hp. I think that's a bit of an overstatement. It "feels" faster and more powerful, but there's a couple things I don't like. Having no tach, I have no idea how far I can take first. Having no speedo, I can't duplicate shift points. Haven't gotten close to the rev limiter, but you can feel its winding up too high and losing power.
Other then that, the car is awesome! I've got over 10hrs drive time on it right now. It feels like a completely different car, and is so much more fun to drive. It definately is getting way better gas mileage, when I keepp my foot out of it. You can tell 5th is an economy gear, but 4th is good for any freeway speed or grade. I took the car up parleys canyon, its a 3-6% grade the entire way. Car sucked it up at 1/4 throttle in 4th. 5th was basically useless for most of it.
Why no speedo
Congrats on the swap! I can totally relate:D
Well a stick over auto you will pick up some hp but not a whole lot
And unless you want to do this again any time soon I would take it ez lol
T5's are pos
But glad you got it all to work good
I agree a T5 cant pull a FAT GIRL OFF A BIKE WITHOUT BREAKING!! But the swap was good and thought out to a point. Just a point if i may. Fourth gear is one to one. But with an auto in high gear all that is different is converter slippage. But i think you did a good job on the project. Now the 68 thousand dollar question. What is the gear ratio of the TRANNY. That is the deciding factor on the difference in performance. Thanks
3.35 first, .68 od. Same 2.73 rear.
Auto should have been very close to the t-5, don't remember off of the top of my head.
No speedo because the 99+ mustangs combine the oss and vss speedo sensor. My dad is going to work on a basic stamp controller to convert it to a different frequency. Either that or a 1999+ dash swap ;).
I know that t-5's can let go fairly easy, but generally its someone with sticky tires drag racing. With stock sized tires and stock 190k 5.0 s.o. I'm really not worried about it. My boss actually has a stock t-5 behind a supercharged 5.0 mustang. He's put over 50k on it and beats the out of it and its fine. The 99+ v-6's are rated at 330lbft and are actually the strongest t-5's from the factory.
I like it because I no longer have a failing auto and it only costed me about $400, start to finish. $150 for the trans, $120 for the clutch kit, $50 for clutch cable and free pedals, $30 for a junk yard starter. I was only getting 200 miles of range on the auto city, and it overheated freeway with no overdrive. I have no accurate odometer, but I drove 222+ miles to the nevada border and back, and used less then half a tank, down shifting everytime I got the chance and beating the out of it in the city.
I'm going to brim the tank before the drive to montana, and shoot for a 550+ mile range. When I did freeway at 55mph with the auto in my last bird, I could average 35mpg freeway with a range of 650-700 miles. Total drive is approx 893 miles.
It's really rated at 330 ?
I just sold a z spec that's rated at that
You might have cooling issues if it's overheating on the highway with no OD. I've got a non lock up converter in mine so it spins about 2800 rpm in OD at 70mph. The engine never gets over 195* even in 90*+ weather on the highway. At 190K the original radiator might be shot ;).
It's possible he meant the transmission overheating. That's how I read it. Perhaps it was puking fluid.
The AOD is 2.4 first and 0.67 overdrive. 2.4 with 2.73s didn't provide much acceleration from a stop. Going to a wide ratio transmission like the 4r70w sure helps getting going with its 2.84 first gear. It gives me better torque multiplication in 1st gear with a 3.08 rear as an AOD with 3.55s in the back.
With a stick, I'd want a six speed with a really tall 6th gear while using 3.73s in the rearend. I don't remember if they go beyond 0.62. I'd love to get back to 33-34mpg while getting more gearing in the lower gears.
Edit: Yep, they go down to 0.5 for the 6th gear in the T-56...that's similar to running a stock AOD and 2.73s in terms of highway rpms.
Yup, 1st gear is fairly short. Still at least 35mph I think.
But no, the car never actually did overheat, but was close to the red freeway. I have a new thermostat, but it doesn't get above the r in "norm" now.
And yes, the v-6 trans is fairly close to the "z" spec trans. I think I'll blow up the 7.5 rear or u-joints before the trans will let go. I beat the out of it and haven't even smelled clutch yet.
Yeah, around 2000 Ford's v6 and v8 transmissions got pretty strong. I have no complaints about the 2003 v6 4r70w bolted to my 306. The aftermarket controller on the other hand...
I think the t-56 is the ultimate upgrade trans. Before the magnum series came out, I really wanted the viper spec tranny so I could run low gears and get a good od with the .5 ratio 6th.
Now I think I'll want some more engine before I need to worry about anything too much beefier. Gonna stick with stock sized tires and the 190k engine is a bit tired. I think if this job works out, I oughta be able to afford the trick flow top end kit, but now I'm thinking just a ford explorer intake and some aluminium heads and stock h.o. cam. But pleanty of little things I can do before that. I'm thinking full length subframes and replacing the shocks and dropping my sn-95 springs in the front to drop the nose a bit. I routinely have 500-600lbs of work tools in the trunk, and working out of town will only make that a more common occurance. Think I'm going to get air shocks and maybe a small -500lb sized trailer as time goes on. But we will see how this job works out.
As it sits now, i'd be happy with a 550 mile range, but calculating mileage will be about impossible till I get the speedo/odometer worked out. Hoping to do the 893 mile drive in about 2 tanks, gonna try to make it all in one solid run, only stopping for gas. I have managed 650-700 miles on a tank with the aod in my last bird. But that was 55mph and a reletively all flat highway run over the course of about 4 days.
Meh. Don't really need a tach - just shift when it stops pulling. After driving it for a bit you'll figure that point out just by the feel, and you'll know to upshift just before it happens. Few people that drive standards daily watch the tach while driving, it's all ears and ass. An SO 5.0 will pretty much smother itself before it spins itself apart (can't get enough air to rev high enough). About the only way you'd spin one apart would be to miss a shift or downshift into the wrong gear
I am doing the same swap on my Sport Coupe. Where did you find the harness connector to plug in the interlock switch on the pedal assembly?
I initually tried to hook the nss from the aod to the sensor on the quadrant. It was the opposite of what I needed though. It wouldn't start with the clutch down that way. I actually have a partial manual trans harness from a foxbody mustang, I only used the reverse lights plug and jumped the nss.
I have part of the sensor that goes right above the clutch pedal, but it was broken and didn't function so I just left it off.
I agree completely. But with no speedo, and no tach, I'm basically stuck with guessing speed or using gps for a speedo. I might just take my old kick stand phone case and sticky tape it to the dash to get me by. I'm really tempted to just run an aftermarket guage setup where this car just has the stupid base cluster. Not worth it for an anolog/digital swap. Plus I could just order the guage for a 99+ mustang for the speedo. Could always swap the 99+ dash cluster/dash or actually play with the electronics/speedo pickup to get it to read right. For now, I'm just gonna drive the shiznit out of it.
Ain't that the truth, even a stock HO falls on it's face around 5400, just wind it till she quits pullin' and grab another gear... RPMs are more limited by the wimpy valve springs vs air flow, my E6 headed '86 Stang with 5-speed would pull hard till around 5300 and lay down just like the E7 heads... What's fun is have a high revver with a good set of heads, my TW heads would pull hard all the way till the 6250 fuel cut off...
BTW congrats on a successful swap, sounds like you done good...
For max MPG, keep advancing the timing till it spark knocks at light throttle on the hills then back off slightly...
Thanks tom.
Initial mpg report... about 31.5 mpg with over 600lbs of tools and 75-85mph sustained, estimated.
No odometer till I get the speedo figured out. Google maps puts me at 480ish miles and 15.2 gallons put back in. I'm happy :).
That's really good mpg
had a t5 behind a 351 Cleveland in my 70 cougar , if you can drive and keep your clutch adjusted properly they are pretty reliable, if your clutch is not adjusted you start grinding your scryo cogs thats when every one starts breaking gears, send all you got my way ill take them.
ive never seen anyone get 35mpg before,,is that a typo?
Nope, but that's a straight freeway run, nice and easy on the hills.
35mpg is hard to believe, I know of many people on forums with 5.0 SO's in their cars, and none of them have ever reported that high of an mpg. Most I ever saw with my old 5.0 SO was 28mpg, and that was on a mostly straight highway run, 55-70mph, no hills, and with me driving like granny the whole time. It was lucky to see all of 14mpg in stop and go city driving though. The engine was fully tuned up, and running like a top at the time too.
I averaged between 14 and 19mpg city when I was doing pizza delivery. The key is to not use any extra throttle or downshift on hills, or use cruise.
Best I was able to calculate over a tank of gas was about 36mpg. That was doing 55 mph following work trucks with a 55mph top speed over about 50 miles each was for about a week straight, I got 693 miles to that tank before filling up, but it was running on fumes. The digi dash calculated a bit lowed due to idle time.
Doing 65-75mph I averaged about 28, but could dip as low as 25 if I maintained the speed limit and I could get 30mpg consistantly by slowing down to about 62mph.
On the way to montana, I went from salt lake to butte montana on 3/4 tank. I put about 15 gallons back in, and I had some around town driving on that tank before I left. I can't calulate exact mileage because my odometer doesn't work, but gps put me at about 450 miles I believe. That was loaded down with about 600lbs worth of tools. I actually got pulled over for an "obstructed rear window" in idaho and searched for drugs because my rear was sagging so bad.
Having 2.73 gears and a light foot helps. On the way back I would guess I only got 25mpg but I had my foot in it trying to get home before midnight so I could work the next day in utah.
I shoot for about 550 miles when I fill up generally. If I could keep my foot out of it, I think I could do much better then that with the stick then I used to get out of my old bird with the aod.
I actually practice hypermiling occasionally, and have pulled down some freakish mpg figures from certain vehicles, but have never got that high with the 5.0 so. There is a guy on Lincolns Online with a Mark 7, that claims to have knocked out 32mpg with an SO in front of a T-5, which is the highest mpg I have ever seen anyone claim before yours. So, if your calculations are correct, then you truly have a Freak of Ford motor there, and I would hang onto that one. Because nobody else on the web that I've seen, is getting that high of an mpg with an 5.0 so.
I can't stay out of teh boost for long enough to see any real MPG outta my lil 2.3. I usually average around 12-15mpg. No idea how high it could really go with hypermilling, as I've never driven it even close to easy enough to find out, lol.
I can have a pretty heavy foot at times.
My last bird I could hit the same numbers. I do advance the timing a bit and do a tuneup, but nothing more then that.
My crown vic I can't get above 22mpg no matter how I drive it, but it does a better 16-19 in the city, so I drive around town in that a lot more then the freeway.
