I bet your 0-60 times will gone up, as you'll have to shift to 2nd before 60 now....Just saying, if I were you, i'd do your pulley swap/other mods first just to see how you like it, as it will be such a huge difference in the way it feels....you may not want a lower gear..

ie..My car has stock 355's, and at the 600rwhp mark there is no way id go lower in a manual trans....just too much power and too short of gear IMO.....if i were auto, that would be different....Im curious to see how you like it a 373 in that car...

How do you find the new Michelin Pilots Sports? Most guys run at least a Drag Radial for street traction....


i would agree with the 3.73 choice.

My car stock has 3.45 gear and its too long for my car. I will be opting for 3.7x gear very soon as well.

It seems like with cars with our power and our weight on a manual trans, these would net the best results from our power levels. Now it can vary depending on the trans gearing which i am not familiar with in his car exactly but i know it uses a tremec which is the same as mine so it cant be that far off.

Finishing the 1/4 mile i have to shift into 4th gear, but i finish at a low rpm. My 4th gear tops out at around 165mph, which i will never see with my power levels. By going to a 3.73 gear, that brings my 4th gear top speed down to between 140-45 depending on redline.

What you have to see is where power is produced, I have a bunch of TQ as soon as my turbos spool which is around 3200 rpm, so this would be ideal launching rpm with sticky tires. What happens with a taller gear is the car will bog off the launch. So by putting a taller gear in will make me shift a lot quicker, (example: i can reach 61mph in my first gear now, after the gear swap it will be ~47mph) but it allows me us to get in our power band quicker and stay in it more.

but yes it would all depends on his power and torque curve and trying to match it up with gearing and tires. The 3.73 is the most popular gear for our style cars up until about 850whp+ then they opt for stock gearing.

But seeing as his is supercharged vs turbo, might be able to pull out a little hard from the whole. But i still vote a 3.73

Change "pull out a little hard from the whole" to roast the tires taking off at a light, shifting into 2nd, shifting into 3rd, etc.. I mean, the car can do that now.....I can't wait for 100hp more and lower gears, LOL.

I've seen John drive his Jeep though so I'm guessing him driving this thing is much different from my driving even when I think I'm driving good since it's John's car. LOL.

I would actually really like to see John drive this car while I ride shotgun, get the full experience.....

I'm not sure....I was wondering the same thing.



See, what I've heard more than anything from John is that "first gear is useless on this car, I spin out so easy."

And that's with how it sits now.

Now, I have no problems with first gear.......however adding ~100hp and 3.73s along with going to a tire with a higher treadwear rating is going to definitely make things more fun or challenging depending on driver skill level.

Personally, I agree with going with the wider tires.....however I would have gone with a stickier compound (lower treadwear generally). And probably would have tried to go bigger up front or at least matching brand/model tire (personal preference, two different tires bother me).
I'm not a Mustang owner so I don't know what all can be done to these things......beyond there being a lot of stuff to make mo powah. LOL

The truth is that I do drive very carefully most of the time, and don't really push vehicles to their limits unless I am on open highway. So my concern with too much power down low caused by swapping the gears out doesn't really affect me because I don't abuse the power. I know for a fact Dan would be a much more fun "driver" for this car if you wanted to be a passenger but I am ok with that.

Again, I am new to Mustangs and RWD and am figuring things out by trial and error. No one has to agree with my decisions, and I am not even positive whether I have made the right decision for me. I will find out by testing this setup and go from there.

from the "hole" sorry, autocorrect took over on my phone. That is correct if you are taking off from every red light with your foot the floor then the tires would spin. Fact is, you are right it would do it with the current gear too.

I am strictly referencing what will benefit at the drag strip.. Because on the street its all about disciplined driving.

Thats all you can do is test and tune. The suckiest part about these cars is traction.

i still think the 3.73 is a good choice. Get some stick tires in the back, do a second gear burnout to get the tires really sticky, and play with your RPM and let her go. The best trick is feathering the clutch. But it will all come with time.

I'd love to see what the car is capable of. I have seen videos of them, LOL. I just tool around when I've had to drive it for the tires and color matching and stuff.
I'm not new to RWD as all my trucks are.....I can actually break the rears loose on my 10,000lb F-450 shifting into 2nd when it's wet out, gotta love 4.88 gears. LOL

And don't get defensive Stuppy Puppy, LOL. It's a fun car. I know some people who know a thing or two about these if you ever want to get some advice. Was actually talking to a friend this morning who knows the guy who did the tune on your SCT. LOL

Actually you have to just barely be on the throttle not to spin in 1st right now. 1/3 to 1/2 pedal is enough to spin some at a red light. It's easy to take off without spinning in any gear IMO and still move out......all controlled by your feet as you know.

It's John's car so I've never been above half throttle in any gear and can break them loose in 1st, 2nd and 3rd if I wanted.
