GEAR RATIO FOR SPEED. plz help

I'm trying to make my Toyota Tacoma run faster
I have a V6 4.0 second gen Tacoma and I am thinking of regearing it.

I'm seeing a lot of different ways you can do this but no straight answers.

what year would be the best for speed. PLEASE HELP

 

Some useful tips in this recent thread: https://www.tacomaworld.com/threads/4-56-or-4-88.659478/

 

Deep pockets? Regear both ends, taller wheels and tires lower it cover the bed. You do realize it's capable of will over a 100MPH stock.

 

Hell I have 285s and can run 100 all day. Fast enough for me.

 

What do you mean?? Get to fastest top speed on interstate, faster mph. at XXX rpm.? Not really sure what you're saying.

Regear is best bang for the buck I’m full armored with almost a 34in E rated tire with 4.56. My truck definitely pulls harder than it did completely stock.
Best way to get it done it thru East coast gear supply and get a 3rd member and front clam shell already assembled comes with a warranty, Pricey but good customer service.
Otherwise you’d be looking at forced induction options which has its own aray of cost and issues.

 

Higher gear (numbers, lower ratio) faster off the line, lower gear (numbers, higher ratio) faster top speed. There is no straight answer.

 

Supercharger.........

 

It might not make sense but you have that backwards. A 3.73 is considered to be a higher gear than 4.56 for example. So a lower gear such as the 4.56 will provide more torque do to higher engine RPM at a given speed. That is what creates a (faster off the line) response but will also require a transmission to shift sooner. A higher gear (3.73) will not always provide a higher top speed. There is a lot of factors involved there. But in general a 3.73 would than a 4.56 especially with a stock or just slightly larger tire than stock tire. But with a 34-35 it may not. For instance with a 33" tire a 4.10 gear ratio is about as close as you can get to the stock overall gear ratio that a 3.73 with a 30" tire is. It is all about matching gearing and tire size with where the engine makes its power when it come to acceleration. Don't forget choosing a lower gear ratio such as that 4.56 is also chosen to help control acceleration on descents to avoid having to use excessive braking.

 

I was referring to the number itself. 5.13 is higher than 3.73, but yes, I should've elaborated.

 

Just asked my better half of we could put that in her Corolla. She gave me that, "what's that" look. I asked her if she wanted to feel the hand of God pushing her down the road... After a couple seconds, ummmm, yeah, NO thank you. Lol

 

The guys running in NASCAR are using gears around 6.50:1. I varies slightly depending on the track.

 

I could see that for a short track and with likely 600-700HP and the ability to run 8k plus rpms. The care and tolerances that go into the engines is way beyond what goes into any production engine. I had the opportunity to visit a number of Nascar shops with behind the scenes access eleven years ago and the extent to attention to details by the bigger teams was impressive. Not to the level of F1 but still impressive.

 

Riding around on the angry hand of God is what the KTM 1290 is for.

 

I'm doing a rear mount turbo just like STS..
I'm building my own kit and I want to put internals in my motor I just recently found a place where I can get camshafts Pistons rods all sorts of different things that would be really good for the internals..
I'm not really talking about top speed I'm talking about quickness and then after that top speed I can hit a hundred all day long but I would like to go 180 but the governor won't let me I want to upgrade my tachometer and get a 200 miles per hour gauge cluster and get real crazy

 

Are you for real?

 

yes I am yes sir

 

I'm trying to figure out if there's a tuner out there or a place I can go so they can tune up my truck I can hit a hundred miles an hour and pretty much 4th gear..
so if I can just get this thing tuned up I'm pretty sure I can go 150 160 easy I'd like to go real fast I'm building a race truck but I'm not getting much help as a lot of YouTube videos where people are going nuts with their tacomas but they're not sharing much information

 

The Ram SRT10 has been known to hit 150 with a long enough runway, but it has the advantage of four extra pistons pushing it there.

The only hope you have of coaxing a taco to 180 is a JATO.
