top speed
its very annoying to be cruisin down the highway basically floored at 75mph. So I was wondering what I could do to get my top speed up so I could actually be able to driveon the highway. I have the 3 speed automatic transmission.

Well, a couple of questions. WHat is your gear ratio? 2wd or 4wd? Any Intake mods? Exhaust mods? Your 3 speed auto can only do so much. What kind of RPMs are you hitting at 75 mph? What is your tire size? ........:humm:Brain fart.......

pretty sure gear ratio is 3:08 its 4x4. Has a K&N intake filter, the exhaust is straight back but is still stock, and im hitting around 2500 rpm at that time. I can hit 90 if im really trying to torture my truck.
---AutoMerged DoublePost--- tires are 31 inch |
While not knowing the rolling radius of those tyres, 3:08 gears with direct drive will give you somewhere close to those speeds at 2500 rpm
|
so what are you suggesting I do?
|
Overdrive gears are about the only way you will get the engine rpm down.
Your maxxed out on final drive ratio. Being a 4X it may take some doing, different transmission with over drive is required. Sorry for the good news |
thanks man

x2. If ya wanna bring down the RPMs and increase speed, Look into an overdrive unit and split the gears. You will essentially end up with a 6 speed trans. Lower RPMs at 75 will also net you much better MPGs. Even better if you slow it down some. The good Lord gave us multi-lane highways and streets so others can pass if they think youre too slow.........:w2:
|
If you have enough driveline length you maybe able to squeeze an overdrive unit behind the trans but being 4x4 you will only be able to use it in high range 2 WD drive.
Sounds more like an overdrive setup out of a later model would be the easiest. |
