Will Hondata Not Solve Low End Torque?

Gday,

We all know that the S2K screams wonderfully and driven within the right band, is very rewarding.

I keep reading threads about people complaining the S2's low end torque is a severe downside.

Is it not a good idea then to perhaps get a Hondata and remap the curve and bring on a greater amount of torque?

Some people could argue it's a lot of money for little results, but then again, is it really?

You'd be putting in $1.5k all up (I've not checked the costs) for Hondata vs other possible mods (t/charging, s/charging, etc)?

Thoughts anyone?

To increase torque, you need to increase volumetric efficiency. There is only so much that you can do using ignition timing and fuel control to increase low rpm torque.

Hondata can only do so much to the stock engine, you can't expect it to just magically pull extra torque out of nowhere without any other sort of modifications.

As far as i know hondata doesnt offer anything for the s2000 pre 06 model.

Also if you want to increase lower end 'torque' or pull of the car invest in a final drive. Works out to be about $1k all up installed.

Please tell where from, for about $1k. As i'm struggling to find a gearset for that price let alone install price.

honda engines need to rev to make power?
do people expect 300nm+ of torque at like 3000rpm?

you can get the Kia 4.77 gear set for under $500.00 from KIA themselves.

this is normal for S2K, Supercharger is there to solve the problem for low end torque on S2K.

+1 gearing changes would be the best bfyb mod to get it to accelerate quicker (read: more low end).

the s2k is a highly strung car from factory, probably why it is such a fun car to drive. however this in turn means there is not much we can do to get more power out of them without spending a lot of money.

:thumbsup::thumbsup:

The S2000 doesn't actually lack low end torque. It just appears to because it has so much power up top. If you compare an MX5 and S2000 in the 0-6000 rpm range the S2000 lacks nothing.

+1. especially when compared to a rex the s2k down low is actually pretty good.

if you want more down low power there is a common saying "there is no replacement for displacement", a 2litre na which revs to 9000rpm will only have so much power down low

lmao amen to that Jaeyon lol "no replacement for displacement"
currently on the chopping block in my back yard is a 1969 XT Falcon sedan and im sourcing parts to build a Monster 408ci Windsor ;)

on the other hand the S2K is awsome and i wanna get that goin quick too by means of forced induction :D

super charge it !

i wouldnt bother abt the s2k having low end torque ... esp when it can rev to 9 k

Roots type supercharger, yes.

Centrifugal type supercharger like the Comptech, SoS and Vortech systems, no, unless you intend up the boost past the stock low boost 7psi, then you will notice a bigger torque difference down low.

Ofcourse, there is always the turbo option.

I agree with what you have said above.

However here's what gets me: the DC2R has a smaller engine (1.8L) and is much more torquey down low than the S2K - even with a 5 speed gearbox.

Is it the weight? Or is it the fact that its rev limiter is 500rpm lower and the engine is mapped slightly lower down?

DC2R VTEC engagement - 5600rpm (or is it 5400rpm?)
S2000 VTEC engagement - 62000rpm?

That's not really true. What you're "feeling" is not necessarily accurate. There are a few reasons why you may "feel" the DC2R is "much more torquey" down low.

- Yes, it's about 70 kilos lighter;
- It has much shorter gearing. It's final drive is also 4.40:1 stock versus 4.10:1 stock for the S2000;
- Brainwashing from journo's.

The F20C's torque curve is actually quite flat, and it produces more torque than the B18C5. Everywhere. Check out the dyno charts. It bewilders me why so many Australian mags crapped on about the S2000's "lack of torque". Compared to what?! It is only a NA 2.0L. Ever driven an RX8? It has much shorter gears and a 4.78:1 FD, and it's still gutless!

Firstly its about 180Kg lighter

My dad had an S2000 and used to drive it regularly. I now own a DC2R and am looking to sell and go back to the magical S2K.

The short gearing may contribute as well but its one thing to read about a car and its another to drive....

I found with the S2K that if you're in the right gear (not necessarily VTEC); there is no shortage of torque. you need to know how to drive it.

iv never driven one, but iv been in the passanger seat of one, and i dont know wat people want, its got enough go to get away from traffic with going past 4k.

do people want aussie six off idel tourqe with honda 9k redlines???

My bad - I mistakenly had the DC5's specs in mind. Almost 200 kilos and a 4.78:1 FD will make a big difference in responsiveness. Also, just to clarify, I meant to say that magazines over time can propagate generalisations and convince those none-the-wiser - even if the occasionally drive the car.

You are highlighting something important about the S2000 though - it does not reward lazy drivers.

Indeed. Thats why I love it. :) :thumbsup:
