Chin spoiler enhance / help track performance?

[ibDursty]

I'm attending my first HPDE at NSXPO and was wondering about the chin spoiler. On my NSX the previous owner either removed the chin spoiler or it possibly could have been removed by 'accident', I'm not really sure. I've heard the chin spoiler helps a little with high speed stability which I'm assuming is a good thing. At this point I'm not sure I can get my chin spoiler replaced in time before NSXPO since I only have about week left. Is it going to be a problem at the track if I don't have the chin spoiler there? I'm not sure what kind of speeds we will be hitting on some of the straightaways where the spoiler would start having a positive effect on handling.

After having just come off my first HPDE (Roebling Road), I'll be the first to tell you that the level of your driving will pale in comparison to the available performance of the car, chin spoiler or not. You won't notice either way. Focus on tires, brake pad/fluid, and most importantly, learning...

Thanks, I was kinda concerned they would say something about it, more than my driving skills, LOL. I'm going ahead and getting fresh pads, new brake fluid, new front tires... hope that will cover it. I might try and see if the dealer can get a new chin spoiler anyway but I'm glad it's not really required.

Please don't worry about it.

Just make sure that your car is safe, and have a lot of fun!

I would be interested in knowing how much difference addition aerodynamics will make though..

For example, is driving an NSX Type-R a lot different from driving a standard NSX in terms of downforce, and do you only feel it at very high speeds? The main factor, is it worth spending a few grand on getting the NSX bits?

The new Ferrari 360 replacement has a load of downforce, whereas the NSX doesn't actually produce any as far as i know. I appreciate a chin spoiler by itself makes no difference but if you're doing trackdays/racing surely its worth adding bits..?

Items like R-rear wing, chin spoilers, vented hoods and side fins for the NSX are reducing the upforce a bit (due to some wind channel tests here in Germany at 200 km/h the stock NSX has some upforce, the NSX-R has less - I posted that numbers in another thread).

My subjective experience on some of the european F-1 tracks is that some of the items helped to stabilize the car in fast corners, such as Eau Rouge and Blanchimont in Spa or in the full throttle right corner after the hairpin in Hockenheim (about 200 km/h). Don't expect much effect at less than 160 km/h.

If you drive slow tracks you may not feel any difference.

Thanks for the post NSX Racer. So does the NSX-R still produce upforce?

I don't know much about aerodynamics, so excuse me if this is a stupid question, if i got a bigger wing that is on the NSX-R would it produce more downforce and also at lesser speed?

I had a look at your website and your NSX looks great!

Cheers,

Rob, you may look here for details.

The effect if the R wing is of course at the whole speed band but the difference at below about 160 km/h is marginal. OTOH the R wing doesn't cost you much top speed - well designed.

i don't think its worth fiddling with aero tuning unless you are doing some sort of competitive driving... and also until you have a good grasp of the baseline grip your car provides. Of course, once you are a experienced driver, you will likely be able to feel the progressive effect of the aero. Matching your aero components to the power and suspension setup would require a lot of experimentation or computer modeling... which is really not necessary until you HAVE to beat someone.
