Heel and toe/flywheel question

[TURBO2GO]

Guys I am wondering... am I the only one that is annoyed by how the stock engine "hangs" when I tap the throttle on heel and toe downshifting? I can't always be precise with my blips and sometimes the motor is actually revving TOO high. The engine drops RPM's VERY SLOWLY. Have any of you noticed this? I am kind of thinking a lightweight flywheel would feel a lot better! Right?

Exactly. Exedy or RPS twin discs and lightweight flywheel cure it. You'll be much happier.

So why does the factory make this heavy piece? What is better about it? My clutch is going anyway, I was thinking of going with the SOS sport clutch. But that is just mildly lighter than stock. Maybe enough. I don't know. I am just glad I am not the only one that finds the stock one downright annoying.

I just managed to get my pedals in order last year with some Autovation pedals that I drilled almnost at the EDGE of my gad pedal to get them a lot closer together. At WGI I was heel and toeing very smoothly finaly, I was proud of myself. LOL... I was following F430's and they were all heel and toe'ing and I was like wow these guys are all good coming into the corners... then realized its the computer of the F1 trans doing it all. Wussies...

More rotational mass makes starting from a stop easier without stalling. I don't have any supporting evidence but it might be cheaper to make, absorb vibrations, etc...

Just go with the RPS or OS Giken. Lighter, much stronger, good pedal feel.

wow dave heel and toe......probably more like big toe/little toe:tongue: Indeed the oem clutch/flywheel was designed to make the car smoother and more of a gt in its everday driving, which if you drive on the street alot is a good thing. I have been very happy with the sachs clutch resold over the years as the comptech powergrip 1. The lighter flywheel really will be a revelation for you if you are downshifting quickly and always in vtec on track:smile:

I have no experience with heel and toe shifting.
However, my current NSX is a NA2 with the single-disc clutch arrangement.
My previous NSX was a 1994 NSX with the dual-disc clutch and I can tell you that car responded IMMEDIATELY on every input I gave it.

Compared to the 1991-1996 I think the single disc clutch was simply NOT a very good design change that Honda put through in 1997.
Currently my clutch is still ok but whenever I will need to change it, I will most probably choose the SOS Sport Clutch package instead.
First of all, my car will loose some more weight, second, the engine will respond quicker.

Just to give you an idea, when Honda designed the 2002 NSX-R, they went back to the dual-disc clutch arrangement. I supposed engine response was the main reason they did this.

Dual-discs have more surface area and holding capacity for the same weight pressure plate (pedal effort). Has to do with alot more than just single vs. dual discs.

In the end, less rotational weight from a lighter clutch/flywheel arrangment will rev up quicker.

Dave you actually have to get to a track to make this modification worthwhile, maybe you should hold off for a bit to make sure you will actually get out there first.

Did you get your fancy Nurburgring tuned suspension installed yet? Wait, never mind that, did you take your car cover off yet?

If you think the stock NSX combo is bad, you should try heal/toe an 8L V10. It takes forever to come back from the moon if you overshoot the mark.

I'm going to install the SOS sport clutch once my stocker takes a dive. It slips on hard launches, hopefully it'll go sooner rather than later.

Don't know that I'd go spending 2-3k to improve my heel and toeing.....maybe more time spent practicing the technique would be more beneficial, certainly more economical! :biggrin:
