60 Mph at 2500 Rpms

[10thAnnivCB7]

This might not be a big deal to some of you guys but my car used to be at 3000 Rpms to hit 60 Mph.

I also hit 70 mph at 2800 rpms.



Cleaning your IACV can do wonders.

Anybody better than this ?

sounds like it has something to do more with lockup. iacv controls idle...

x2 your tcc or torque converter clutch is "locked up" to your impeller during highway speeds lowering rpms and improving MPG... "Over Drive"

[10thAnnivCB7]

the IACV is the only thing i worked on and the car is way better in gas and i do feel a gear that slows my rpms down and keeps the car goin fast as u said overdrive.

Im guessing that is good but wed3k doesnt seem to agree.

[jewelproject]

i can do 70mph at 2500rpms (5th)
also 90mph at 3200rpms (5th)
i have an h series intake. includes tb, plenum, intake manifold. plus short ram.
the iab is hooked to a vaccum line.
....i dont see what the big issue is?

[10thAnnivCB7]

i dont understand either ,, he is talking about TCC but i only cleaned my IACV ,, i dont know why but doing that made my overdrive work because i never saw the car do that

jewelproject is referring to a car with manual transmission. The automatics should run at about 2500 rpm in 4th with the torque converter completely locked up (according to the service manual, there are several stages of partial lockup, but it just may go through these while getting to full lockup). While working on the IACV did you mess with the throttle cable to the transmission? How long have you had the car?

[wed3k]

an iacv doesn't control lockup. thats like putting in an aftermarket deck makes me do better burnouts.

My manual 5 speed stock f22a1 with over 250k does 70 at 2800 or so. Well I do have cold air intake and exhaust but that's it right now.

Rpm at a certain speed has to do with gearing.

Ive had it for almost a year now. My stepdad actually got it about a year and a half but barely rode it because when we bought the car it had a fart can and shinny 18 inch rims.

I tried like 3 TCUs and this is the only time overdrive has ever kicked in.

I would waste a full tank of gas in 3 days and in the last 3 days i am a bit just under half. saving so much money

Did you happen to do anything to the coolant system? I noticed when I took my thermostat out (car never got up to operating temperature), overdrive never worked. Seems like it will only work once the vehicle is at normal operating temperature.

[10thAnnivCB7]

yup ,, new thermostat and coolant too ,, maybe that gave it the right operating temperature and made the overdrive work.

[Bad_dude]

So how many miles you get to the tank now?

[10thAnnivCB7]

not sure man ,, i dont know the way to figure it out or the formula.

i drive 78.9 miles to school and back and i drove 3 days and im just under half because i was having a little bit of fun on the streets after i left my girlfriend home.
