NSX-R vs BMW M6

[AR]

Even when it first came out it was no faster than the competing Carrera (964) and Ferrari (348) in a straight line

You sure about this I am sure it was faster than the 348. Well mine is.( where is the evil smiley ? )

[AR]

If brakes is the main weak point of the NSX, then why are Type R disc more better than OEM? I understand that they are the same diameter front & rear on the 1997+ or 3.2. I understand that the other factors such as harder/more performance pad material has its benefits, braided lines ensuring fluid pressure & air deflectors for channelling more cool air to the brakes.

Different metal and temper compounded with different pad compounds and better airflow.

Just my .2 p and all that.

Yes, most magazines recorded mid 5's (0-60) and 158-161mph for the early NSX while the 348 was low 5's and 165mph+. I'll dig out my copy of Car Magazine, circa Oct 1990, when they compared the NSX with the 348, Carrera 2 (964) as well with an Esprit Turbo.

The performance differance is barely enough to notice when running side by side but if either car is off colour it'll be the slower one.

Remember it's just as easy, probably easier, to release a few more ponies (or take some weight out) from the Porsche and Ferrari as it is the NSX.

There was a particularly fast 348 at one of the VMAX days. It ran 166mph into a strong headwind that reduced Carrera 993's and M3's to about 150mph!

Which adds up to 0.0001% improvement

I'm not sure I believe the metal temper story, did they dip them a slightly differant acid OR add one more heat/cool cycle OR hold the discs in for for 2 more secs? If this works so well why not do the same to the non grooved ones?

Airflow, for cooling, is the same i.e. same deflectors, disc ventilation. The grooves help the pad gases escape which is a slightly differant thing. Of course the grooves actually reduce the friction area.

Fundamentally the discs are too small to absorb then release the heat generated in hard circuit driving. You can fiddle around the details and find some small improvements but this is an occassion where bigger really is better

A marginal improvement can be made from 2 piece discs, but I'm not sure that even that makes enough difference. Heat dissipation is certainly improved.

Is this a question or question and part answer to your own question?

NSX-R for the 02 variant differs by having grooved discs, more aggressive pads and larger pistons in the calipers. Deflectors and hoses I beleive are as all other NA2.

MY set up is R discs, braided hoses, MU's and oversized deflectors. Nex tstep if I take it would be to increase disc sizes as previously discussed with Mark when looking at the AP and RB discs.

Mark,

On track at CC and Donnigton and due to the openess of both circuits, brakes have performed well. I agree that more track focussed tyres may well change the outcome. If only I had some sticky rubber I could use

Paul, I'm confused sometimes with my Q & A!

Should have known just to stick to the disc only!

Mark,

The disc guars were different on my NA1R than in my NA2 or my current NA1.

As for the 348 I can only speak from my experience. I have a few mags at home, but one mag even went as far as calling the NSX the better car and the 348 the better exotic. It seems most mag writers get all moist when it comes to Ferraris.

The BMW is a fat pile of junk(technical term), so was bound to have trouble getting off the line. The NSX-R can actually use all it's power. Further down the track I'm sure the fat pile of junk caught up and passed.
