For me price is not an issue, I would just spend the money on something else. :-) I just wanted to know, gear's or Super Charger.

 

gears

 

If price is not an issue, get both

 

4.57 or even 4.77 gears will NOT make your car accelerate faster than having 300whp with a SC.

 

a buddy of mine with 4.77's and AEM CAI ran a 13.2 in the 1/4.... and i believe thats about right where a supercharged S runs....

 

Let's be realistic here..
I think many of you are relaying vaguely from where what you have learned elsewhere, which is the foundation of forums in general but I want to clear some things up...

We are talking about adjusting the gearing to a more favorable setup towards max acceleration vs supercharging a car for 100-200hp. Don't get my wrong, gears are a great mod under certain conditions, but even comparing a geared STOCK s2k vs a SC'd STOCK [relativetly speaking, I'm not an idiot] is dumb IMO.

You add ZERO power with gears, you just 'use' it more effectively, whereas with the SC or turbo or NOS you are pushing significantly more power from your drivetrain. Don't get me wrong, gearing is great, but lets not get carried away as if it is magical power.

Another way to put it, no one is going to confuse a SC's or turbo'd car with a s2k that just has gears. It still has 240hp even if you are redlining 6th gear at 90mph.

sc's are not more reliable than turbos, but turbo systems are usually more complex. User error causes reliability problems with turbo systems. How many japanese stock sc'd car are there? How many stock turbo cars are there? Why? Should be self explanatory from a cost/benefit evaluation.

Different platforms are better designed for sc or turbo applications by nature, this effects cost and reliability. The s2k is a poor choice for both compared to most cars, but with its over engineering and forged internals it can still survive.

If you want power, get forced induction or build your motor. If you are in it for pure acceleration, go buy a sportbike [I have 2] or a car with some torque and a stronger rear-end.

 

My $.02:

Gears are cheapest
SC is reliable
Turbo has greatest gains over all IF done correctly.

 

O.K.let's get this straight:
a-)-Stock,well driven S2K = 13.7 sec. 1/4 mile.
b-)-With 4.57,again,well driven,and otherwise stock,= 13.2 sec.1/4 mile.
c-)-With 4.57 +I/H/E,=13 sec.flat,1/4 mile.
d-)-With S.C.(at 5-7-p.s.i.)and otherwise stock,=13.10 sec.1/4 mile.
You can extrapolate the rest.!!!(SC+gears+I/H/E,etc...)
A Turbo could be faster,depending,on how many p.s.i.of boost,you run.!!!
Have a good Day.!!!

 

if a S topped out at 90 mph, that would be damn fast acceleration.

 

Ok, I think I need to clear up my question just a bit. I want to increase the acceleration performance of the S2000. Not for drag racing, but just for the rush of accelerating through the gears with the top down and having fun. Also, to make me feel as if the car will remain more competitive in the years to come. I would prefer not to install the lower gears, as this will affect my highway performance by raising the cruise rpm. So, if a Super Charger can give me all the acceleration of a car with 4.57, or 4.77 gears, but not affect my cruise rpm, than this would be preferable to me. If the Super Charger would not give me as much acceleration as the gears knowing that it cost much more than just gears, I would suck it up and get the gears and hope the increased rpm would not bother me on long freeway trips. But if the Super Charger would give better acceleration than the gears, coupled with the lower cruise rpm, then that would be worth the extra cost of the Super Charger to me. I am not interested really in doing both.

Thanks.
