3.73's in a boosted car. I hear people telling me to change them. May I ask why

traction and you dont have to shift into 5th before the traps

Because you will roast 1-3

3:73 here, 700+whp, lots of fun, not real practical

You're gonna want 3:55s for boost, so I hear.

I don't care about praticality

I have 3.73's and like them just fine. But, I don't go to the 1/4 mile drag strip. Nothing wrong with it, just not my thing. I'm a twists and turns kind of guy and maybe a little roll racing stuff so for that, the 3.73's are perfect for me.

Preference.
Mostly it’s the fact that first gear is incredibly short NA. FI, I’d imagine it’s about useless. Possible solution= start in 2nd if you intend on sending it? It’s not like you wouldn’t slip the clutch some starting in 1st for traction anyway. More expensive solutions = Tremec swap, gear changes, etc.

I haven't had mine to the strip yet but I agree 3.73's are a blast on the street. Having to shift into 5th isn't going to help my times but if I were chasing #'s I would of bought a auto. I just like having fun! Do it OP you wont be sorry!

I have full traction in 3rd gear with a e-force 2300 and indy 500's, I know it's not a crazy amount of power but it's still FI with 3.73's. OP, what are your power goals? The higher you go the more making a gear change makes sense. Some guys just upgrade the opg, sprockets, guides, chains and etc. and let her RIP all the way past 8,000+ rpm which let's you stay in 4th at the strip!

15-17 manual cars do really well boosted with 3.31 gears due to the shorter gears in the MT-82. The '18 up cars are ok boosted with 3.73 gears due to the longer gears in the MT-82D4. All depends on how you like to drive though.

The reality is that it makes your car more driveable, but it'll feel slightly less quick. It also depends on your power adder; imo taller gearing makes more of an impact with PD cars than centri cars, for example.

At the end of the day, it won't be a night and day difference. If you can't use 1st-3rd gear right now, 331s won't all of a sudden make all of those gears usable, but it might at least make 3rd usable again.

That’s pretty sad.

That’s pretty sad.

Spinning isn't winning!

All the power in the world will do nothing if you can't get it down to the ground. Suspension upgrades and a good summer tire is a must for a super charged manual s550.
